The Town of Truckee (Town) is the lead agency for the environmental review of the proposed Coldstream Specific Plan (proposed project) and has the principal responsibility for approving the project. This FEIR assesses the expected environmental impacts resulting from approval and implementation of the proposed project, as well as responds to comments received on the Draft EIR (DEIR). 1.1 BACKGROUND AND PURPOSE OF THE EIR OVERVIEW OF CEQA REQUIREMENTS FOR PREPARATION OF AN EIR The Town, acting as the lead agency, has prepared this EIR to provide the public and responsible/trustee agencies with information about the potential environmental effects of the proposed Coldstream Specific Plan. As set forth in the provisions of CEQA and implementing regulations, public agencies are charged with the duty to consider the environmental impacts of proposed development and to minimize these impacts where feasible while carrying out an obligation to balance a variety of public objectives, including economic, environmental, and social factors. CEQA Guidelines Section 15121(a) states that an EIR is an informational document for decision- makers and the general public that analyzes the significant environmental effects of a project, identifies possible ways to minimize significant effects, and describes reasonable alternatives to the project that could reduce or avoid its adverse environmental impacts. Public agencies with discretionary authority are required to consider the information in the EIR, along with any other relevant information, in making decisions on the project. CEQA requires the preparation of an environmental impact report prior to approving any project, which may have a significant effect on the environment. For the purposes of CEQA, the term “project” refers to the whole of an action which has the potential for resulting in a direct physical change or a reasonably foreseeable indirect physical change in the environment (CEQA Guidelines Section 15378[a]). With respect to the proposed Coldstream Specific Plan, the Town has determined that the proposed development is a “project” within the definition of CEQA. BACKGROUND OF ENVIRONMENTAL REVIEW PROCESS OF THE PROJECT The following is an overview of the environmental review process for the proposed Coldstream Specific Plan that has led to the preparation of this FEIR. Notice of Preparation and Initial Study In accordance with Section 15082 of the CEQA Guidelines, the Town prepared a Notice of Preparation (NOP) of an EIR for the proposed Coldstream Specific Plan on June 5, 2009. The Town was identified as the lead agency for the proposed project. The notice was circulated to the public, local, state, and federal agencies, and other interested parties to solicit comments on the proposed project. The 30-day comment period closed on July 6, 2009. A scoping meeting was also held on June 30, 2009, to solicit input from interested agencies and the public. Concerns raised in response to the NOP and at the scoping meeting were considered during preparation of the Draft EIR. The NOP, responses by interested parties, and comments received at the scoping meeting are presented in Appendix A of the Draft EIR. The NOP’s conclusions supported preparation of an EIR for the proposed project. Town of Truckee Coldstream Specific Plan March 2014 Final Environmental Impact Report 1.0-1 1.0 INTRODUCTION Following release of the original NOP, changes were made to the project description that necessitated release of a revised NOP and a re-release of the DEIR (see below). The revised NOP was issued January 4, 2011, and the comment period ended on February 4, 2011. A scoping meeting was held by the Town on January 27, 2011, to solicit comments on the scope of the analysis that should be prepared for the revised project. The revised NOP, responses by interested parties, and comments received at the scoping meeting are presented in Appendix A of the Draft EIR. Draft EIR The Draft EIR (DEIR) was released for a 45-day public and agency review on June 17, 2011, with the review period set to end on August 1, 2011. The DEIR contains a description of the project, description of the environmental setting, identification of project impacts, and mitigation measures for impacts found to be significant, as well as an analysis of project alternatives. The DEIR was provided to interested public agencies and the public and was made available for review at the Town offices and on the Town’s website. Partially Revised Draft EIR The Partially Revised Draft EIR (PRDEIR) was prepared to address refinements to the project design made by the project proponent as well as additional technical information produced as part of the Clean Water Act (CWA) Section 404 permitting process. The PRDEIR was released for a 45-day public and agency review on October 9, 2013, with the review period set to end on November 22, 2013. The PRDEIR contains an introduction section and two technical sections including descriptions of the environmental setting, identification of project impacts, and mitigation measures for impacts found to be significant. The PRDEIR was provided to interested public agencies and the public and was made available for review at the Town offices and on the Town’s website. Final EIR Following the close of the public review period for the DEIR, the Town received 39 individual comment letters from agencies, interest groups, and the public regarding the Draft EIR. Following the close of the public review period for the PRDEIR, the Town received 2 additional comment letters from agencies. This document responds to the written comments received as required by CEQA. This document also contains minor edits to the Draft EIR as well as an analysis of modifications of the proposed project design. Certification of the Final EIR/Project Consideration The Town will review and consider the Final EIR. If the Town finds that the Final EIR is “adequate and complete,” the Town may certify the Final EIR. Upon review and consideration of the Final EIR, the Town may act upon the proposed Coldstream Specific Plan. A decision to approve the project would be accompanied by written findings in accordance with CEQA Guidelines Section 15091 and, if applicable, Section 15093. The Town would also adopt a Mitigation Monitoring and Reporting Program (MMRP) for mitigation measures that have been incorporated into or imposed upon the project to reduce or avoid significant effects on the environment. The MMRP will be designed to ensure that these measures are carried out during project implementation.

Town of Truckee Coldstream Specific Plan March 2014 Final Environmental Impact Report 1.0-3 1.0 INTRODUCTION This page intentionally left blank Coldstream Specific Plan Town of Truckee Final Environmental Impact Report March 2014 1.0-4 2.0 EXECUTIVE SUMMARY 2.0 EXECUTIVE SUMMARY Town of Truckee Coldstream Specific Plan March 2014 Final Environmental Impact Report 2.0-1 This section provides an overview of the proposed Coldstream Specific Plan and its environmental analysis. For additional detail regarding specific issues, please consult the appropriate section (4.1 through 4.14) of the Draft EIR or (4.8 through 4.9) of the PRDEIR. 2.1 PURPOSE AND SCOPE OF THE FINAL ENVIRONMENTAL IMPACT REPORT This Final EIR, which consists of the Draft EIR, the PRDEIR, and comments and responses to comments as well as minor revisions made in this document, provides a reasonably thorough analysis of the potential environmental effects associated with the implementation of the proposed project, pursuant to CEQA. This Final EIR analysis focuses on potential environmental impacts that could arise from implementation of the proposed project through development of the land uses within the project site, as regulated and guided by Specific Plan policies and actions. The EIR adopts this approach in order to provide a credible worst-case scenario of the impacts resulting from project implementation. 2.2 PROJECT SUMMARY The proposed project is the adoption and implementation of the Coldstream Specific Plan for the 178.6-acre project site located approximately 2 miles west of the Town of Truckee’s historic downtown at the entrance of Coldstream Canyon, just south of Interstate 80 in Nevada County, California. The originally proposed Coldstream Specific Plan that the Draft EIR evaluated included the following components:  Commercial uses are identified in the Village Mixed-Use Commercial zone. A total of 8.6 acres allowing up to 70,000 square feet of retail and commercial uses and lodging are proposed for this zoning district. Residential land uses are also encouraged in this district.  Residential uses are proposed for 54.4 acres total, providing up to 345 residential units (including affordable housing) in the following residential districts: Village Green Residential (11.4 acres), Village Green Residential Small Lot (7.0 acres), Lakeside Residential (25.5 acres), and Forest Residential (10.5 acres).  Recreation is proposed for 7.0 acres of the project site, and 108.6 acres are proposed for Open Space.  The proposed Coldstream Specific Plan includes a wide variety of housing types including mixed-use residential, attached triplex and duplex units, detached residential, and lakeside homes. The proposed project includes a public gathering area located in the heart of the Village Mixed-Use Commercial zoning district.  Another major component of the proposed Coldstream Specific Plan is enhancement of former mining pond areas and restoration of Cold Creek and Donner Creek. This aspect of the proposed project presents preservation, restoration, and enhancement opportunities.  The project also proposes to create a connection from Coldstream Road to Deerfield Drive (with a re-designation of Deerfield Drive) and to construct a new vehicular bridge over Cold Creek to facilitate access throughout the project site. 2.0 EXECUTIVE SUMMARY Coldstream Specific Plan Town of Truckee Final Environmental Impact Report March 2014 2.0-2  A trail network is proposed to connect residential, commercial, and recreational areas in and outside of the project site by providing a linked system of bikeways and recreational trails. The trails system includes a major link to the Truckee Legacy Trail that will ultimately connect to Donner Memorial State Park and Coldstream Canyon through the project site via possible off-site trails. Since release of the Draft EIR, the project applicant has prepared two new land use diagram and roadway design options (Option A and Option B see Figures 3.0-1 and 3.0-2) for the proposed Coldstream Specific Plan in response to feedback provided during a joint workshop held with the Planning Commission and Town Council in September 2011. Project modifications included the following:  The Village Mixed-Use Commercial zone acreage was increased to a total of 9.6 acres, but now included a reduce extent of retail, commercial and lodging development (30,000 square feet) Residential land uses are still encouraged in this district.  Residential uses are reduced to provide up to 300 residential units and changes includes elimination of the Village Green Residential Small Lot and Forest Residential areas.  Recreation has been reduced 3.8 acres under Option A and 6.5 acres under Option B.  The project consists of only two options associated with connection to Deerfield Drive (full access – Option A and emergency only access – Option B).  The General Plan would be amended to re-designate Cold Stream Road from a Local Road to a Minor Collector from the project site to Donner Pass Road. 2.3 PROJECT ALTERNATIVES SUMMARY State CEQA Guidelines Section 15126.6 requires that an EIR describe a range of reasonable alternatives to the project that could feasibly attain the basic objectives of the project and avoid and/or lessen the environmental effects of the project. Further, CEQA Guidelines Section 15126.6(e) requires that a “no project” alternative be evaluated in an EIR. The Draft EIR evaluates the following alternatives:  Alternative 1A – No Project No Development Alternative. Under this alternative, no development of the project site would occur. The project site would remain in its current undeveloped state. This alternative would not meet the objectives of the proposed project, the Town of Truckee General Plan, or the Truckee Redevelopment Plan, but analysis of the No Project Alternative is required under CEQA Guidelines Section 15126.6(e).  Alternative 1B – No Project Consistent with General Plan Alternative. Under this alternative, the project site would be developed consistent with the existing General Plan land use designation for PC-1, which allows 300 residential units and 70,000 square feet of commercial uses.  Alternative 2 – Reduced Residential Development and Reconfigured Roadway Alternative. This alternative would reduce the number of residential units proposed on the project site by 50 dwelling units east of Cold Creek in the Forest Residential zoning district, resulting in 295 residential units. The roadway system would be modified to provide only emergency access to Deerfield Drive east of the project site (see Figure 6.0-1 of the Draft EIR). All other aspects of this alternative would be the same as the proposed project. 2.0 EXECUTIVE SUMMARY Town of Truckee Coldstream Specific Plan March 2014 Final Environmental Impact Report 2.0-3  Alternative 3 – Wetland Impact Minimization Alternative. This alternative would retain the same overall site design; however, the site design would be modified to avoid wetland impacts in the southern portion and eastern portion of the site (see Figure 6.0-5 of the Draft EIR). This would result in a reduction of 15 residential units for a total of 330 units. In addition, the roadway system would be modified to provide only emergency access to Deerfield Drive east of the project site. All other aspects of this alternative would be the same as the proposed project.  Alternative 4 – Reduced Development Potential Alternative. This alternative would substantially redesign the project through the reduction in the number of residential units by 85 units for a total of 260 residential units, as well as the elimination of 70,000 square feet of commercial uses (see Figure 6.0-6 of the Draft EIR). The roadway pattern for this alternative would be reconfigured to provide an emergency-only access to Deerfield Drive. This reduction in site development would minimize impacts to wetlands as well as avoid project traffic impacts to the I-80 Westbound Ramps/Donner Pass Road intersection. 2.4 SUMMARY OF ENVIRONMENTAL IMPACTS Table 2.0-1 displays a summary of the impacts of the proposed Coldstream Specific Plan and proposed mitigation measures that would avoid or minimize potential impacts. In the table, the level of significance is indicated both before and after the implementation of each mitigation measure. The mitigation measures have been changed based on the analysis provided in Section 3.3 of this document as well as Appendix B to match the modifications to the project design (Options A and B) since release of the Draft EIR. These revisions (as well as revisions based on responses to comments on the EIR) are shown in underline/strikeout format. For detailed discussions of all mitigation measures and of proposed Specific Plan policies and action items that would provide mitigation for each type of environmental impact addressed in the EIR, refer to the appropriate environmental topic section (i.e., Sections 4.1 through 4.14 of the DEIR and Sections 4.8 and 4.9 of the PRDEIR). 2. 0 EXE C U T I V E SUM M A R Y LS – L e s s T h a n S i g n i f i c a n t S – S i gn i f i c a n t B – B e n e f i c i a l PS – P o t e n t i a l l y S i g n i f i c a n t SU – S i g n i f ic a n t a n d U n a v o i d a b l e NI – N o I m p a c t LC C – L e s s T h a n C u m u l a t i v e l y C o n s i d e r a b l e PC C – P o t e n t i a l l y Cu m u l a t i v e l y C o n s i d e r a b l e CC – C u m u l a t i v e l y C o n s i d e r a b l e CB – C u m u l a t i v e l y B e n e f i c i a l Co l d s t r e a m S p e c i f i c P l a n Town of Truckee Fi n a l E n v i r o n m e n t a l I m p a c t R e p o r t March 2014 2 . 0 - 4 TAB L E 2. 0 - 1 EXE C U T I V E SUM M A R Y Im p a c t Le v e l o f Si g n i f i c a n c e Wi t h o u t Mi t i g a t i o n Mi t i g a t i o n M e a s u r e Resulting Level of Significance 4. 1 L a n d U s e Im p a c t 4 . 1 . 1 Th e p r o j e c t s i t e f o r t h e p r o p o s e d C o l d s t r e a m Sp e c i f i c P l a n i s l o c a t e d so u t h o f I - 8 0 a n d e a s t of D o n n e r L a k e .

In addition, further details on the proposed restoration of Cold Creek have been provided for consideration in the Final EIR. PROPOSED MODIFICATIONS TO THE COLDSTREAM SPECIFIC PLAN LAND USE DIAGRAM Since preparation of the Draft EIR, the project applicant has prepared two new land use diagram and roadway design options (Option A and Option B see Figures 3.0-1 and 3.0-2) for the proposed Coldstream Specific Plan in response to feedback provided during a joint workshop held with the Planning Commission and Town Council in September 2011. Table 3.0-1 provides a summary of proposed land use changes as compared to the originally proposed Coldstream Specific Plan.

Residential land uses are also encouraged in this district. 9.6 acres allowing up to 30,000 square feet of retail and commercial uses and lodging. Residential land uses are also encouraged in this district. 9.6 acres allowing up to 30,000 square feet of retail and commercial uses and lodging. Residential land uses are also encouraged in this district. Residential Residential 54.4 acres total providing up to 345 residential units (including affordable housing) including the following residential districts (Note – while not identified in the Specific Plan, the Draft EIR assumed that up to 141 second units could be developed on the site – Draft EIR page 4.0-2): 60.2 acres total providing up to 300 residential units (including affordable housing), and up to 75 secondary dwelling units, including the following residential districts: 56.8 acres total providing up to 300 residential units (including affordable housing), and up to 75 secondary dwelling units, including the following residential districts: Village Green Residential (VGR) 11.4 acres 20.4 acres 20.4 acres Village Green Residential Small Lot 7.0 acres 0 acres 0 acres Forest Residential 10.5 acres 0 acres 0 acres Lakeside Residential (LR) 25.5 acres 39.8 acres 36.4 acres Recreation Recreation 7.0 acres 3.8 acres 6.5 acres Open Space Open Space 108.6 acres 105.3 acres 106 acres Source: Stonebridge Properties, April 2012 Option A As shown in Figure 3.0-1 and Table 3.0-1, proposed Option A would have a reduced intensity of residential and commercial development as well as provide a full connection to Deerfield Drive to the east through the project site utilizing a circuitous roadway system to discourage vehicle trips that pass through the site to access Deerfield Drive and State Route 89 south of Interstate 80. Modifications to the project design also include the following: Town of Truckee Coldstream Specific Plan March 2014 Final Environmental Impact Report 3.0-7 3.0 EVALUATION OF PROJECT MODIFICATIONS AND EIR COMMENTS AND RESPONSES • The Lakeside Residential area has been expanded to generally follow the revised street pattern, and the previously proposed Forest Residential has been eliminated; a portion of these lots is now proposed to be located directly east of the Recreation area. • The Village Green Residential area has been modified to increase buffer areas between the proposed home sites and Donner Memorial State Park consistent with the requirements of Draft EIR mitigation measure MM 4.1.3; a portion of these lots has been shifted to include around the MUC area of the project. • Provision of on-site trailhead parking. • The General Plan would be amended to re-designate Cold Stream Road from a Local Road to a Minor Collector from the project site to Donner Pass Road. All other aspects of Option A are similar to the original Coldstream Specific Plan. Option B Option B would have the same reduced intensity of development and development pattern as Option A. However, Option B would consist of an emergency-only access to Deerfield Drive and the development of a neighborhood park at this location. All other aspects of Option B are similar to the original Coldstream Specific Plan. COLDSTREAM RESTORATION AND MANAGEMENT PLAN/COLD CREEK FLOODPLAIN RESTORATION PLAN As described in Section 3.0, Project Description, of the Draft EIR, a key component of the proposed Coldstream Specific Plan is enhancement of former mining pond areas and restoration of Cold Creek and Donner Creek (see Draft EIR pages 3.0-20 through -27). This information is included in Chapter 3, Section 3.2, of the Coldstream Specific Plan. In addition, Appendix B in the Coldstream Specific Plan provides additional detailed information regarding the proposed project’s Restoration and Management Plan, which includes mitigation and enhancement objectives, design criteria for slope stabilization and wetland creation and enhancement, habitat enhancement, monitoring programs, and long-term management. Since preparation of the Draft EIR, the project applicant provided 25 percent submittal plans for the Cold Creek Floodplain Restoration, and the plans have been included as Appendix A of the Final EIR. The plans provide details for restoration of approximately 2,300 linear feet of Cold Creek. Construction activities include demolition and replacement of the existing bridge located on the project site, channel bank grading, placement of log and boulder structures, and revegetation with native riparian species. The objectives of the restoration work include restoring geomorphically appropriate channel dimensions, restoring vegetation density along the creek channel, improving habitat by creation of inset floodplain and in-stream structures, and reduction in erosion of the stream banks to improve water quality. The plan set includes detailed topography, locations for material stockpiling and equipment staging, plan view and cross-section details of in-stream and floodplain work areas, cross-section details of in-stream work areas, best management practice (BMP) notes and details, and revegetation details. The plans were prepared in consultation with the Truckee River Watershed Council and the California State Department of Parks and Recreation, and a portion of the work is proposed to occur on State Parks property located south and west of the proposed Coldstream Specific Plan area boundaries. Coldstream Specific Plan Town of Truckee Final Environmental Impact Report March 2014 3.0-8 3.0 EVALUATION OF PROJECT MODIFICATIONS AND EIR COMMENTS AND RESPONSES 3.3 ENVIRONMENTAL EFFECTS OF MODIFICATIONS TO THE PROPOSED PROJECT Although the proposed Coldstream Specific Plan has been modified since circulation of the Draft EIR (as described above), no new significant impacts were identified as a result of the modifications. CEQA Guidelines Section 15088.5(a) (Recirculation of an EIR Prior to Certification) states, “New information added to an EIR is not ‘significant’ unless the EIR is changed in a way that deprives the public of a meaningful opportunity to comment upon a substantial adverse environmental effect of the project or a feasible way to mitigate or avoid such an effect…” Significant new information includes: 1) A new significant environmental impact resulting from the project or from a new mitigation measure proposed to be implemented. 2) A substantial increase in the severity of an environmental impact unless mitigation measures are adopted that reduce the impact to a level of insignificance. 3) A feasible project alternative or mitigation measure considerably different from others previously analyzed would clearly lessen the significant environmental impacts of the project, but the project’s proponents decline to adopt it. 4) The Draft EIR was so fundamentally and basically inadequate and conclusory in nature that meaningful public review and comment were precluded. As none of the above scenarios resulted from modifications of the project, recirculation of the EIR is not necessary, consistent with the provisions of CEQA Guidelines Section 15088.5. An analysis of the environmental effects of the modifications for each issue area is provided in the following discussion. Minor modifications to the mitigation measures have been made to match Options A and B and are shown in Table 2.0-1 and Section 4.0. Land Use The Draft EIR identified one potentially significant land use impact associated with potential land use conflicts with the operation of the Donner Memorial State Park that would be mitigated to less than significant with the modification of the site design with the provision of a enhanced buffer and fencing (see Draft EIR pages 4.1-17 through -22 and mitigation measure MM 4.1.3). As shown in Figures 3.0-1 and 3.0-2, proposed Options A and B would incorporate the modification to the site design and would minimize this impact originally identified in the Draft EIR. Transportation and Circulation A revised Traffic Impact Analysis prepared by LSC has been prepared to evaluate these options and is included in Appendix B of the Final EIR. Options A and B would generate the same number of vehicle trips and would result in 369 total summer PM peak hour trips (see Appendix B page 14) as compared to the originally proposed Coldstream Specific Plan that was estimated to generate 491 total PM peak hour trips (see Draft EIR page 4.2-32). Construction Impacts Draft EIR Impact 4.2.1 identified that project construction activities could temporarily generate construction traffic volumes that could exceed Town LOS standards on area intersections (I-80 Eastbound Ramps/Coldstream Road/Donner Pass). This impact would be mitigated through Town of Truckee Coldstream Specific Plan March 2014 Final Environmental Impact Report 3.0-9 3.0 EVALUATION OF PROJECT MODIFICATIONS AND EIR COMMENTS AND RESPONSES implementation of mitigation measure MM 4.2.1 that requires the development and implementation of a Construction Management Plan. Proposed Options A and B could result in the same impact, but would not result in any changes or increased severity of the identified impact given that development potential is less than the original project design. Intersection Operational Impacts for Year 2010 and 2030 Conditions Draft EIR Impacts 4.2.2 and 4.2.11 identified significant LOS impacts to the following intersections: • SR 89 South/Donner Pass Road – for all Specific Plan options under 2010 and 2030 conditions • I-80 Westbound Ramps/Donner Pass Road (western interchange) – for Specific Plan options 2, 3, and 4 for 2010 conditions and all Specific Plan options under 2030 conditions • I-80 Eastbound Ramps/Donner Pass Road/Coldstream Road – for all Specific Plan options under 2010 and 2030 conditions Option A would avoid year 2010 impacts to the I-80 Westbound Ramps/Donner Pass Road intersection, while Option B would not. All other significant intersection impacts identified in the Draft EIR for year 2010 and 2030 conditions would also occur for Option A and B. However, these options would reduce their contribution to summer P.M. peak hour traffic at the intersections from 2 to 6 percent as compared to the original project design (see Appendix B pages 52 through 56 as compared to Draft EIR pages 4.2-58 and -59). Implementation of mitigation measures MM 4.2.2a, b, and c would mitigate these impacts for Options A and B. LSC conducted a phasing analysis of project development under year 2010 conditions to determine at what extent of development would mitigation be required to address deficient level of service operation (full access connection to Deerfield Drive or improvement to the I-80 Westbound Ramps/Donner Pass Road [western interchange] – mitigation measure MM 4.2.2b). The analysis identified the following (see Appendix B): • Assuming all of the proposed project commercial uses are constructed, all of the PC-1 dwelling units to the west of Cold Creek could be constructed. In addition, approximately 37 dwelling units (assumed to consist of 33 primary residences and 4 vacation homes) could be constructed in PC-1 to the east of Cold Creek. A total of about 13 secondary units are estimated to be included to the east of the creek. • Assuming all of the proposed project dwelling units to the west of Cold Creek are constructed, all of the project commercial uses could be constructed in 2010. • Conversely, if all of the project dwelling units are constructed in 2010 without the commercial uses, either the Deerfield Drive connection or improvement to the I-80 Westbound Ramps/Donner Pass Road would be needed, due to an exceedance of the LOS threshold at the I-80 Westbound Ramps/Donner Pass Road intersection. Intersection Queuing Exceeding Storage Capacity Under 2010 and 2030 Conditions Draft EIR Impacts 4.2.3 and 4.2.12 identify potential queuing issues where traffic volumes would exceed available storage lengths at intersections that would obstruct driveways and through lanes at the following intersections: Coldstream Specific Plan Town of Truckee Final Environmental Impact Report March 2014 3.0-10 3.0 EVALUATION OF PROJECT MODIFICATIONS AND EIR COMMENTS AND RESPONSES • SR 89/Deerfield Drive (year 2010 and 2030 conditions) • I-80 Westbound Ramps/Donner Pass Road (year 2030 conditions) • I-80 Eastbound Ramps/Donner Pass Road/Coldstream Road (year 2010 and 2030 conditions) Options A and B would avoid significant queuing impacts under year 2010 conditions for the I-80 Eastbound Ramps/Donner Pass Road/Coldstream Road intersection, but would result in significant queuing impacts for the SR 89/Deerfield Drive. Under 2030 conditions Options A and B result in significant queuing impacts to the SR 89/Deerfield Drive intersection, while only Option B would result in significant queuing impacts to the I-80 Westbound Ramps/Donner Pass Road and the I-80 Eastbound Ramps/Donner Pass Road/Coldstream Road intersections. These queuing impacts would be mitigated through the implementation of mitigation measures MM 4.2.2c and 4.2.3b that include intersection improvements, pavement marks and signage. Options A and B would have reduced queue lengths in comparison to the original project design. Exceedance of Level of Service Thresholds at Study Roadways Draft EIR Impacts 4.2.4 and 4.2.13 identified that the proposed project would not result in an exceedance of LOS for project area roadways under 2010 or 2030 conditions. Options A and B would result in the same LOS conditions (LOS D) under 2010 and 2030 conditions similar to the proposed project (though traffic volumes would be reduced). Conflicts with Existing Goals and Policies Draft EIR Impact 4.2.5 identified that the proposed project options 2, 3, and 4 would conflict with General Plan Circulation Element Policy 2.4 and Goal CIR-4 and result in a significant impact. Under Option A, average daily traffic (ADT) one-way trips on the local roadway segment of Deerfield Drive east of the project area would be reduced to 950 trips and would be consistent with Policy 2.4 and Goal CIR-4. Option B would conflict with these policy provisions similar to originally proposed Coldstream Specific Plan options 2, 3, and 4. This impact would remain significant and unavoidable for Option B. Inadequate Emergency Access Draft EIR Impact 4.2.6 identified that the proposed project would be consistent with the Town’s emergency access standards. Options A and B would also be consistent with these standards. Inadequate Parking Capacity Draft EIR Impact 4.2.7 identified that the proposed project would provide adequate parking. Options A and B would also provide adequate parking. Pedestrian/Bicycle Conflicts and Consistency with Trails and Bikeways Master Plan Draft EIR Impact 4.2.8 identified that the proposed project would not result in substantial conflicts between motor vehicles and pedestrians/bicyclists and is consistent with the Town of Truckee’s Trails and Bikeways Master Plan. Options A and B include the same proposed trail system design as the originally proposed Coldstream Specific Plan as well as trailhead parking that was not originally proposed. Town of Truckee Coldstream Specific Plan March 2014 Final Environmental Impact Report 3.0-11 3.0 EVALUATION OF PROJECT MODIFICATIONS AND EIR COMMENTS AND RESPONSES Conflicts with Transit Policies, Plans or Programs Draft EIR Impact 4.2.9 identified that the proposed project would not result in substantial conflicts with policies, plans, or programs for transit service. Options A and B would also not result in any substantial conflicts. Exacerbation of an Existing Traffic Safety Deficiency Draft EIR Impact 4.2.10 identified that the proposed project may exacerbate an existing traffic safety deficiency within the project site. Mitigation measures MM 4.2.10a through d were identified to address this impact. Options A and B would also result in the same potential traffic safety impacts. In addition to mitigation measures MM 4.2.10a through c, LSC has identified an additional mitigation measure that would require the project site’s Primary Road internal “T” intersection to be either modified as through movement or provide signage directing through traffic away from the cul-de-sac. Noise The Draft EIR identified the following significant noise impacts for the proposed project: • Construction Noise Impacts (Impact 4.3.1) – reduced to less than significant by implementation of mitigation measures MM 4.3.1a and b • Exterior Traffic Noise Impacts at the Project Site Under Project and Cumulative Conditions (Impacts 4.3.3 and 4.3.9) – reduced to less than significant by implementation of mitigation measure MM 4.3.3 • Interior Traffic Noise Impacts on the Project Site (Impact 4.3.4) – reduced to less than significant by implementation of mitigation measure MM 4.3.4 • Traffic Noise Impacts to Existing Residents along Deerfield Drive for Option 1 Under Project and Cumulative Conditions (Impacts 4.3.5 and 4.3.9) – reduced to less than significant by implementation of mitigation measure MM 4.3.5 • On-Site Retail/Commercial Noise Source Impacts Under Project and Cumulative Conditions (Impacts 4.3.8 and 4.3.9) – reduced to less than significant by implementation of mitigation measures MM 4.3.8a through c While Options A and B would reduce the overall development intensity on the project site, it would still result in the same significant but mitigable noise impacts. Options A and B would reduce the extent of future resident exposure to traffic noise as well as reduce the potential extent of retail and commercial noise. Air Quality The Draft EIR identified the following significant air quality impacts for the proposed project: • Construction Air Quality Impacts (Impact 4.4.1) – reduced to less than significant by implementation of mitigation measures MM 4.4.1a and b • Operational Air Quality Impacts (Impacts 4.4.3 and 4.3.9) – reduced to less than significant by implementation of mitigation measure MM 4.4.3a and b Coldstream Specific Plan Town of Truckee Final Environmental Impact Report March 2014 3.0-12 3.0 EVALUATION OF PROJECT MODIFICATIONS AND EIR COMMENTS AND RESPONSES • Exposure to Mobile-Source Toxic Air Contaminants (Impact 4.4.6) – reduced to less than significant by implementation of mitigation measure MM 4.4.6 • Cumulative Air Quality Operational Impacts (Impact 4.48) – significant and unavoidable even with implementation of mitigation measures MM 4.4.3a and b While Options A and B would reduce the overall development intensity on the project site and associated air pollutant emissions (stationary and mobile), it would still result in the same significant air quality impacts. However, no new air quality impacts would occur beyond what was identified in the Draft EIR. Geology and Soils The Draft EIR identified the following significant geologic impacts for the proposed project: • Geologic and Seismic Stability Impacts (Impacts 4.5.2 and 4.5.3) – reduced to less than significant by implementation of mitigation measures MM 4.5.2a and b • Stability Issues Associated with Shallow Groundwater (Impact 4.5.4) – reduced to less than significant by implementation of mitigation measure MM 4.5.4a and b • Radon Exposure (Impact 4.5.5) – reduced to less than significant by implementation of mitigation measure MM 4.5.5 The development areas of Options A and B are substantially the same as those analyzed in the Draft EIR for the originally proposed Coldstream Specific Plan and would not result in new or increase severity of geologic impacts beyond what was identified in the Draft EIR. Hazards and Risk of Upset As described in the Draft EIR, the project site is located within an area designated as a very high fire hazard area (see Impact 4.6.4). This impact would be reduced to less than significant with the implementation of mitigation measure MM 4.6.4. Development of Options A and B would also place residents and structures in this very high fire hazard area (though less development would occur) would not result in new or increase severity of fire hazard impacts beyond what was identified in the Draft EIR. Hydrology and Water Quality The Draft EIR identified the following significant hydrologic impacts for the proposed project: • Construction Water Quality Impacts (Impact 4.7.1) – reduced to less than significant by implementation of mitigation measures MM 4.7.1a through c • Increase in Stormwater Runoff Rates (Impact 4.7.2) – reduced to less than significant by implementation of mitigation measure MM 4.7.2a and b • Operational Water Quality Impacts (Impacts 4.7.3 and 4.7.4) – reduced to less than significant by implementation of mitigation measures MM 4.7.3a and b • Flood Hazards (Impact 4.7.5) – reduced to less than significant by implementation of mitigation measures MM 4.7.5a through c Town of Truckee Coldstream Specific Plan March 2014 Final Environmental Impact Report 3.0-13 3.0 EVALUATION OF PROJECT MODIFICATIONS AND EIR COMMENTS AND RESPONSES • Cumulative Hydrologic Impacts (Impact 4.7.6) – reduced to less than significant by implementation of mitigation measures MM 4.7.1a through c, MM 4.7.2a and b, MM 4.7.3a and b, and MM 4.7.5a through c Project modifications would result in similar construction water quality impacts to those identified in the Draft EIR and would not substantially increase project water quality impacts beyond those that were disclosed and mitigated in the Draft EIR, given the land area to be developed under Options A and B would be similar. Stormwater runoff rates and volumes would increase under Options A and B compared to existing conditions; however not beyond those analyzed in the Draft EIR. Development of Options A and B would increase local runoff production and would introduce constituents (sediments, heavy metals, petroleum hydrocarbons, pesticides, and fertilizers) into stormwater that are typically associated with urban runoff. However, impacts to surface water quality and groundwater quality would not be greater than those identified in the Draft EIR due to the reduced development intensity of the proposed project modifications. Since preparation of the Draft EIR, the project applicant has provided additional detail on project-proposed restoration, which consists of 25 percent submittal plans for the Cold Creek Floodplain Restoration (see Appendix A). The plans provide details for restoration of approximately 2,300 linear feet of Cold Creek. The construction water quality impact of this restoration activity was addressed in Draft EIR Impact 4.7.1 and mitigation measure MM 4.7.1c specifically addresses this water quality impact with the identification of Best Management Practices. No new or increased severity of environmental effects from the proposed restoration would occur beyond what was addressed in the Draft EIR. As with the proposed project evaluated in the Draft EIR, some of the proposed site development areas in Options A and B would place structures in the Special Flood Hazard Area (100-year floodplain) and within and adjacent to areas currently occupied by ponds associated with prior aggregate mining activities. See Figure 4.7-5 in the DEIR for the areas of the project site that are within the currently designated FEMA 100-year floodplain. However, as described in the Draft EIR, Brown and Caldwell (2002) performed a hydraulic analysis utilizing USACE’s HEC-RAS computer model to determine the boundaries of the 100-year floodplains for Donner Creek and Cold Creek in greater detail than the level of detail employed to develop the Flood Insurance Rate Maps (FIRMs). The analysis utilized updated and detailed topographic mapping (1-foot contour interval, which is of substantially greater detail than was used by FEMA) as a basis for modeling the passage of the 100-year discharge and for mapping the boundaries of the 100-year floodplain. In particular, the hydraulic analysis and mapping of the 100-year floodplain for Cold Creek was substantially more detailed than the analysis performed by FEMA. Brown and Caldwell utilized the 100-year discharges for Donner Creek published in the FEMA FIS and an estimated 100-year discharge magnitude of 2,480 cfs for Cold Creek as a basis for completing their hydraulic analysis. The flood boundaries determined per the Brown and Caldwell analysis are depicted on Draft EIR Figure 4.7-6, which consists of Plate 1 from the Brown and Caldwell analysis report. The flood boundaries resulting from this more detailed analysis utilizing updated topographic mapping were generally narrower and more confined to channel areas, particularly along Cold Creek, than the boundaries represented on the FEMA Flood Insurance Rate Maps. In addition, Options A and B would include safety factors built into the proposed site design that would be adequate to address greater variability in flow regimes in Cold Creek that could occur in association with climate change. Coldstream Specific Plan Town of Truckee Final Environmental Impact Report March 2014 3.0-14 3.0 EVALUATION OF PROJECT MODIFICATIONS AND EIR COMMENTS AND RESPONSES Biological and Natural Resources The Draft EIR identified the following significant project and cumulative biological resource impacts for the proposed project: • Impacts to Habitats and Individuals of Endangered, Threatened, and Rare Plant and Wildlife Species (Impacts 4.8.1 and 4.8.8) – reduced to less than significant by implementation of mitigation measures MM 4.8.1a through g • Impacts to Habitats and Individuals of “Fully Protected” Plant and Animal Species (Impacts 4.8.2 and 4.8.8) – reduced to less than significant by implementation of mitigation measure MM 4.8.2a through c • Impacts to Sensitive Biological Communities (Impacts 4.8.3 and 4.8.8) – reduced to less than significant by implementation of mitigation measure MM 4.8.3a through c • Wetland Impacts (Impacts 4.8.4 and 4.8.8) – reduced to less than significant by implementation of mitigation measure MM 4.8.4 • Tree Removal Impacts (Impacts 4.8.7 and 4.8.8) – reduced to less than significant by implementation of mitigation measure MM 4.8.7a through c While Options A and B result in less development intensity than the originally proposed Coldstream Specific Plan evaluated in the Draft EIR, the development footprint and associated habitat disturbance would be substantially similar. However, impacts to biological resources would not be greater than those identified in the Draft EIR. Since preparation of the Draft EIR, the project applicant has provided additional detail on project-proposed restoration consisting of 25 percent submittal plans for the Cold Creek Floodplain Restoration (see Appendix A). The plans provide details for restoration of approximately 2,300 linear feet of Cold Creek. The construction water quality impact of this restoration activity was addressed in Draft EIR Impact 4.7.1, and mitigation measure MM 4.7.1c specifically addresses this water quality impact with the identification of Best Management Practices. In addition, Draft EIR Impacts 4.8.1, 4.8.2, 4.8.3, and 4.8.4 and associated mitigation measures also address potential restoration impacts. No new or increased severity of environmental effects from the proposed restoration would occur beyond what was addressed in the Draft EIR. Historic and Cultural Resources The Draft EIR identified the following significant project and cumulative cultural resource impacts for the proposed project: • Impacts to Undiscovered Prehistoric and/or Historic Resources (Impacts 4.9.2 and 4.9.5) – reduced to less than significant by implementation of mitigation measures MM 4.9.2a and MM 4.9.2b • Impacts to Paleontological Resources (Impacts 4.9.3 and 4.9.6) – reduced to less than significant by implementation of mitigation measure MM 4.9.3 • Impacts to Human Remains (Impacts 4.9.4 and 4.9.5) – reduced to less than significant by implementation of mitigation measures MM 4.9.2a, MM 4.9.2b, and MM 4.9.4 Town of Truckee Coldstream Specific Plan March 2014 Final Environmental Impact Report 3.0-15 3.0 EVALUATION OF PROJECT MODIFICATIONS AND EIR COMMENTS AND RESPONSES Options A and B could potentially impact prehistoric, historic and paleontological resources, and human remains in the project area on both a project-specific and cumulative level to a similar extent as identified in Section 4.9, Historic and Cultural Resources, of the Draft EIR. However, the reduction in proposed development intensity would not result in greater impacts than those identified in the Draft EIR. Visual Resources/Light and Glare The Draft EIR identified no significant visual impacts associated with the originally proposed Coldstream Specific Plan. Options A and B could reduce the overall development intensity on the project site including the mixed-use commercial area. In addition, the project modifications include increased buffer areas along the western boundary of the project site adjacent to Donner Memorial State Park. Due to implementation of extensive design guidelines provided for in the Coldstream Specific Plan and standards contained in the Town of Truckee Development Code, impacts to degradation of visual character or a scenic vista, nighttime lighting and daytime glare, and cumulative degradation of scenic resources are considered less than significant, as discussed in the Draft EIR. No mitigation measures are required. Community Services The Draft EIR identified the following significant project community service impacts for the proposed project: • Increased Demand for Fire Protection and Emergency Medical Services (Impact 4.11.1.1) – reduced to less than significant by implementation of mitigation measure MM 4.6.4 • Impacts From Increased Recreation Use of Donner Memorial State Park (Impact 4.11.3.2) – reduced to less than significant by implementation of mitigation measure MM 4.11.3.2 Options A and B reduce the overall development intensity on the project site and would not increase the number of residential units or amount of commercial square footage that may require fire protection and emergency medical services beyond what was addressed in the Draft EIR. Potential increase the use of existing trails and associated facilities in Donner Memorial State Park would also be reduced under Options A and B. No new or increased severity of environmental impacts would occur beyond what was addressed in the Draft EIR. Utilities and Service Systems The Draft EIR did not identify any significant environmental effects associated with utility service for the proposed project. Options A and B would result in reduced utility service demand as compared to the originally proposed Coldstream Specific Plan. No new or increased severity of environmental impacts would occur beyond what was addressed in the Draft EIR. Population, Housing, and Socioeconomics The Draft EIR did not identify any significant environmental effects associated with population/housing or employment for the proposed project. Options A and B would result in reduced population and employment generation potential as compared to the originally proposed Coldstream Specific Plan. No new or increased severity of environmental impacts would occur beyond what was addressed in the Draft EIR. Coldstream Specific Plan Town of Truckee Final Environmental Impact Report March 2014 3.0-16 3.0 EVALUATION OF PROJECT MODIFICATIONS AND EIR COMMENTS AND RESPONSES Greenhouse Gases and Climate Change The Draft EIR identified that the proposed project may conflict with the greenhouse gas (GHG) emission reduction goals of AB 32 and identified that implementation of mitigation measure MM 4.14.1 would reduce this impact to less than significant. Options A and B reduce the overall development intensity on the project site that would result in reduced GHG emissions. No new or increased severity of environmental impacts would occur beyond what was addressed in the Draft EIR. 3.4 LIST OF COMMENTERS ON THE DRAFT EIR AND PARTIALLY REVISED DRAFT EIR The following individuals and representatives of organizations and agencies submitted written comments on the Draft EIR and the Partially Revised Draft EIR.

The commenter further states that the California State Parks owns and operates Donner Memorial State Park adjacent to the proposed project site and owns another parcel adjacent to the project that is isolated from access by Cold Creek and the Stonebridge properties. The comment does not pertain to the adequacy of the Draft EIR. The comment is noted. Response F-2: The commenter states that on page 2.0-6 of the Draft EIR, the first bullet under mitigation measure MM 4.1.3 should be revised to read Donner Memorial State Park. The indicated text in the Draft EIR has been revised. The reader is referred to Section 4.0, Minor Revisions to the EIR. Response F-3: The commenter notes that on page 3.0-2 of the Draft EIR, text indicates that the Specific Plan shall include policies and design measures to ensure development on the project site is compatible with and shall not adversely affect the historic or natural character of Donner Memorial State Park. The commenter then states that while some modifications to the proposed project have been made to address this, they believe that Donner Memorial State Park will be adversely affected by the proposed project if additional mitigation measures are not addressed. The commenter does not provide specific information regarding the adequacy of the Draft EIR and does not provide additional recommended mitigation measures to address their concerns. Town staff has determined that the Draft EIR provides an adequate analysis of the proposed project’s physical environmental impacts to Donner Memorial State Park. Response F-4: The commenter summarizes the discussion on page 3.0-20 of the Draft EIR related to enhancements of the former mining areas (pond areas) and restoration to Cold Creek and Donner Creek, and claims the Draft EIR’s statement regarding the lack of detailed improvement plans being prepared resulted in this aspect of the project being analyzed at a programmatic level is inaccurate. The commenter further states they have been working with the project applicant over the past several years to develop floodplain enhancements for Cold Creek, and the 25 percent design report for the Final Cold Creek Floodplain Enhancement project prepared in August 2010 by Waterways and River Run Consulting is sufficient for the impact analysis and inclusion in the EIR. The commenter further states that the enhancement components are proposed for Phase I of project as noted on page 3.0-50 of the Draft EIR and that these improvements should be constructed prior to other site improvements and in conjunction with the bridge replacement. Coldstream Specific Plan Town of Truckee Final Environmental Impact Report March 2014 3.0-50 3.0 EVALUATION OF PROJECT MODIFICATIONS AND EIR COMMENTS AND RESPONSES Since preparation of the Draft EIR, the project applicant has provided additional detail on project-proposed restoration consist of 25 percent submittal plans for the Cold Creek Floodplain Restoration (see Appendix A). The plans provide details for restoration of approximately 2,300 linear feet of Cold Creek. The construction water quality impact of this restoration activity was addressed in Draft EIR Impact 4.7.1 and mitigation measure MM 4.7.1c specifically addresses this water quality impact with the identification of Best Management Practices. In addition, Draft EIR Impacts 4.8.1, 4.8.2, 4.8.3, and 4.8.4 and associated mitigation measures address potential restoration impacts as well. No new or increased severity of environmental effects from the proposed restoration would occur beyond what was addressed in the Draft EIR. Response F-5: The commenter notes that Number 4 (Cold Creek) on Figure 3.0-7 of the Draft EIR should not be referred to as “potential future enhancement,” as this aspect of the project is included in Phase I and provides water quality, flood protection, and habitat benefit, along with aesthetic and recreational enhancements to the proposed project. The commenter is referred to Response F-4. Response F-6: The commenter notes discussion on page 3.0-39 of the Draft EIR pertaining to the project’s proposed new bridge to be constructed over Cold Creek, replacing the existing bridge. The commenter states they have been working with the applicant and its consultants (Waterways and River Run) to coordinate the bridge replacement, and HECras modeling has determined the existing 40-foot-long bridge will need to be replaced with a 60-foot-long bridge to accommodate a broader floodplain, along with other proposed enhancements for Cold Creek. The commenter further states this component of the project must be analyzed in the EIR. The Draft EIR analyzed the development footprint of the proposed primary road to be constructed between Coldstream Road and Deerfield Drive, including the bridge crossing over Cold Creek. The length specific design details of the bridge are not required for evaluation in the Draft EIR, as the Draft EIR assumed impacts to the development footprint area wherein this roadway and bridge crossing will be constructed. The fact that the bridge crossing would be 60 feet long instead of 40 feet long does not affect the analysis in the Draft EIR, because the roadway on either side of the bridge crossing would be reduced by a total of 20 feet. However, it is still within the development footprint analyzed in the Draft EIR. Response F-7: The commenter notes the discussion on page 3.0-40 and Figure 3.0-15 of the Draft EIR pertaining to trail connections from the proposed project to Donner Memorial State Park. The commenter supports mitigation measure MM 4.11.3.2 regarding the project’s requirement to coordinate with the California Department of Parks and Recreation staff and Town staff on future trail alignments and compatibility of uses, as well as on signage. The commenter is acknowledging support of mitigation measure MM 4.11.3.2 being required as part of the proposed project. The comment is noted. Town of Truckee Coldstream Specific Plan March 2014 Final Environmental Impact Report 3.0-51 3.0 EVALUATION OF PROJECT MODIFICATIONS AND EIR COMMENTS AND RESPONSES Response F-8: The commenter notes the discussion on page 3.0-49 of the Draft EIR pertaining to soil import. The commenter states that the discussion does not include material that will be imported to the proposed project site from the adjacent CA State Park Floodplain Creation project. The excavated material is approximately 7,000 cubic yards of clean gravels and sands that will be transferred to a disturbed area on the proposed project site by truck less than ¼ mile in distance all on internal roads not used by the public, and will be used by the proposed project at a later date as subgrade and fill material. The addition of 7,000 cubic yards of material, on top of the 60,000 cubic yards described in the Draft EIR, constitutes results in an increase of approximately 12 percent of additional imported soil material. Spread out over the developed areas of the project site, this amount of imported soil material does not result in a significant increase in project soils. The material would be clean gravels and sand, and therefore pose no risk from hazardous materials. Importing the soil material from the adjacent CA State Park Floodplain Creation project would not result in impacts to traffic on local roadways or additional construction air quality impacts as the materials would be moved internal to the project site using on-site construction equipment already anticipated as part of Phase 1. The commenter is referred to Appendix A of this document for plans showing the storage location of the material The indicated text in the Draft EIR has been revised. The reader is referred to Section 4.0, Minor Revisions to the EIR. The revisions made to the text do not alter the analysis or conclusions contained in the Draft EIR and would not result in additional or more severe environmental impacts than those addressed in the Draft EIR. Response F-9: The commenter states that the Mixed-Use Commercial (MUC) area of the proposed project needs to incorporate a 100-foot defensible space area around structures per Public Resources Code 4291 and that the California State Parks will not allow this defensible space to occur on park land. Draft EIR mitigation measure MM 4.6.4 includes Town and Truckee Fire Protection District requirements for fuel modification, access, hydrant location and fire flow. No defensible space for the project is proposed on State Park lands. Response F-10: The commenter requests that native conifer trees and shrubs be established between the MUC area and Coldstream Road for visual screening from Donner Memorial State Park. As noted on pages 4.10-26 and -27 of the Draft EIR, the existing recreational uses (campsites) in Donner Memorial State Park west of the MUC zoning district are set back from Coldstream Road and are at a substantially lower grade than Coldstream Road and the project site. Existing trees and vegetation, coupled with the project’s proposed landscape buffer along the western boundary of the project site, would provide a visual screen of future development in the MUC area from Donner Memorial State Park. In addition, Draft EIR Figure 4.10-4d depicts a Coldstream Specific Plan Town of Truckee Final Environmental Impact Report March 2014 3.0-52 3.0 EVALUATION OF PROJECT MODIFICATIONS AND EIR COMMENTS AND RESPONSES visual simulation of future vegetation along the project’s western boundary adjacent to the VGR zoning district. No additional mitigation is required. The commenter is also referred to the modifications in the project design (Options A and B) since release of the Draft EIR shown in Figures 3.0-1 and 3.0-2. Response F-11: The commenter requests that a continuous fence be installed along the project boundary between the proposed project and Donner Memorial State Park so future residents and visitors are aware of private and public property jurisdictions. The commenter further states the fence should be constructed at the start of the first phase of the development’s construction and maintained in perpetuity by the project. The commenter is referred to Figures 3.0-1 and 3.0-2 in this document associated with new project design Options A and B since release of the Draft EIR that include fencing between the project and Donner Memorial State Park. Response F-12: The commenter provides suggested changes to the Draft EIR text on page 4.1-18, second paragraph, to include additional language regarding adjacent land uses west of the project site. The indicated text in the Draft EIR has been revised. The reader is referred to Section 4.0, Minor Revisions to the EIR. The revisions made to the text do not alter the analysis or conclusions contained in the Draft EIR and would not result in additional or more severe environmental impacts than those addressed in the Draft EIR. Response F-13: The commenter notes that mitigation measure MM 4.1.3 on page 4.1-21 of the Draft EIR modifies the western buffer and residential parcels along the Village Green Residential Small Lot area on the western boundary of the proposed project adjacent to Donner Memorial State Park to include a 100-foot residential setback and 6-foot durable fence. The commenter supports mitigation measure MM 4.1.3 as long as the 100-foot setback is provided and fencing is maintained in perpetuity by the project or its homeowners association. The commenter is acknowledging support of mitigation measure MM 4.11.3.2 being required as part of the proposed project. As the 100-foot setback will be from the western property line of the project site, maintenance of this area will be the responsibility of the current and future property owners. This mitigation measure has been incorporated into the design of Option A and B that have modified the project design and reduced the intensity of development (see Figures 3.0-1 and 3.0-2). Response F-14: The commenter notes that mitigation measure MM 4.1.3 on page 4.1-21 of the Draft EIR provides for gated access to the proposed project’s Recreation parcel from the California State Parks property for use only by the California State Parks and requests a legally recorded, deeded access easement across the proposed project’s property. Town of Truckee Coldstream Specific Plan March 2014 Final Environmental Impact Report 3.0-53 3.0 EVALUATION OF PROJECT MODIFICATIONS AND EIR COMMENTS AND RESPONSES The commenter is acknowledging support of MM 4.1.3 being required as part of the proposed project. Mitigation measure MM 4.1.3 has been modified to include the easement language. The commenter is also referred to Figures 3.0-1 and 3.0-2 associated with the new project designs for Options A and B that now show this access point. Response F-15: The commenter notes that there is a typo on Figure 4.1-5 of the Draft EIR and requests the state park located west of the proposed project be referred to as “Donner Memorial State Park.” The indicated text in the Draft EIR has been revised. The reader is referred to Section 4.0, Minor Revisions to the EIR. Response F-16: The commenter suggests an Open Space Management Plan needs to be expanded beyond the document submitted in the Coldstream Specific Plan, Appendix B, Cold Stream Restoration and Management Plan. The commenter suggests that the Open Space Management Plan document existing conditions and address issues that can threaten the integrity of the preserved and enhanced areas of the development including processes that influence or maintain the habitats, detection and eradication/control of invasive non-native terrestrial and aquatic invasive species, and management of upland vegetation and forest health, as well as administrative aspects, such as identification and responsibilities of the open space manager(s), long-term funding sources, etc. The commenter offers to work cooperatively with the open space manager(s) to provide consistent open space management for the adjacent properties. The comment pertains to preparation of the proposed project’s Specific Plan Restoration and Management Plan and does not pertain to the adequacy of the Draft EIR. These comments are noted. Mitigation measures identified in Sections 4.7, Hydrology and Water Quality, and 4.8, Biological and Natural Resources, address several of the concerns identified by the commenter. Response F-17: The commenter states that noise associated with permitted and temporarily permitted events occurring in the proposed project’s various zoning districts should not impact Donner Memorial State Park and that the noise associated with events should be no greater than the park’s existing ambient noise levels when in Donner Memorial State Park. This comment is associated with the Specific Plan and is noted. No specific special events have been identified as part of the project. Draft EIR Section 4.3, Noise, provides an analysis of the project’s potential impact to existing ambient noise conditions in relation to Town noise standards. Response F-18: The commenter expresses concerns with noise being transferred between the proposed project site and Donner Memorial State Park, and cites a demonstration that was conducted in May 2011 wherein a chainsaw was started on the park’s campground property as an example of noise transfer (in addition to noise associated with Caltrans operations). The Coldstream Specific Plan Town of Truckee Final Environmental Impact Report March 2014 3.0-54 3.0 EVALUATION OF PROJECT MODIFICATIONS AND EIR COMMENTS AND RESPONSES commenter suggests installing a noise berm similar to the one proposed in mitigation measure MM 4.3.3 between the proposed boundary fencing and the Village Green and Small Lot Residential uses to decrease transfer of noise between the park and the proposed project as well as address vehicle headlight impacts on the park. Noise associated with the current operation of Donner Memorial State Park and Caltrans are part of the existing setting and are not considered impacts of the project under CEQA. As shown in Draft EIR Table 4.3-2, ambient noise measurements of the project site generally showed that on-site noise levels are within the Town’s noise standards. The noise analysis prepared for the Draft EIR did not identify any ambient noise impacts associated with uses at Donner Memorial State Park operation. While occasional chainsaw noise coming from the campground site on the park property may be audible at the proposed project’s Village Green and Small Lot Residential uses, this type of noise source is considered temporary, thus does not require a permanent mitigation measure such as that proposed in mitigation measure MM 4.3.3. The commenter is also referred the visual simulation on Draft EIR Figure 4.10-4d that demonstrates adequate screening to avoid any potential lighting impact in addition to the fact that the residential lots face the park rather than the project roadway. Response F-19: The commenter states that pursuant to mitigation measure MM 4.3.1a, they would like to be notified with information on the construction schedule and telephone number for noise complaints. Mitigation measure MM 4.3.1a requires the proposed project to designate a “disturbance coordinator” responsible for responding to any local complaints about construction noise and includes a requirement that the project applicant send a notice to neighbors in the project vicinity with information on the construction schedule and the telephone number for noise complaints. This would include California Department of State Parks and Recreation, as they are a neighbor of the proposed project. Response F-20: The commenter refers to mitigation measure MM 4.3.1b and requests additional restrictions be placed on the proposed project’s construction activities adjacent to Donner Memorial State Park’s campground between Memorial Day and Labor Day to be between the hours of 8 AM to 5 PM Monday through Friday, with no construction activity on Saturdays, Sundays, or holidays. The commenter states this will reduce noise impacts to the campground during the summer months when camping activities are occurring, which generates money to help keep the park open and operating. As described in mitigation measure MM 4.3.1a, construction activities associated with the proposed project shall adhere to the requirements of the Town of Truckee with respect to hours of operation, muffling of internal combustion engines, and other factors which affect construction noise generation and its impacts on noise-sensitive land uses such as the park’s campground. Additional restrictions on construction periods are not required to mitigate this temporary noise impact. Town of Truckee Coldstream Specific Plan March 2014 Final Environmental Impact Report 3.0-55 3.0 EVALUATION OF PROJECT MODIFICATIONS AND EIR COMMENTS AND RESPONSES Response F-21: The commenter requests text changes to Impact 4.4.3 on page 4.4-22 of the Draft EIR pertaining to exposure to wood smoke from prescribed burns at Donner Memorial State Park. The indicated text in the Draft EIR has been revised. The reader is referred to Section 4.0, Minor Revisions to the EIR. Response F-22: The commenter describes ongoing prescribed fire suppression activities related to thinning vegetation at Donner Memorial State Park. The commenter states that smoke generated by the prescribed fire suppression activities (pile and understory burning) settles in low-lying areas such as the proposed project, exposing sensitive receptors (humans) to smoke. Comment noted. Mitigation measure MM 4.3.3b provides disclosure to future residents regarding this activity. Response F-23: The commenter states that they disagree with the statement on page 4.4-22 of the Draft EIR related to exposure to wood smoke from prescribed burns at Donner Memorial State Park which states, “The occurrence of such events is expected to be infrequent and not an ambient air quality condition in the project.” The commenter further indicates they conduct prescribe burns under permit when weather and other environmental conditions are met. As noted by the commenter prescribed burns are only conduct on specific environmental conditions and are not a year-round or ambient condition. No change to the Draft EIR is recommended. Response F-24: The commenter states that they would like the proposed project to cooperatively work with the California Department of State Parks and Recreation in an effort to educate future residents about the benefits of prescribed fire. The commenter is referred to mitigation measure MM 4.4.3b on pages 4.4-23 through -24 of the Draft EIR. Response F-25: The commenter requests that the word “occasional” be dropped from the last sentence of the first paragraph on page 4.4-24 under mitigation measure MM 4.4.3b of the Draft EIR. The indicated text in the Draft EIR has been revised. The reader is referred to Section 4.0, Minor Revisions to the EIR. The revisions made to the text do not alter the analysis or conclusions contained in the Draft EIR and would not result in additional or more severe environmental impacts than those addressed in the Draft EIR. Response F-26: The commenter refers to the third bullet under mitigation measure MM 4.6.4 of the Draft EIR under the subheading Wildland Fire Protection, stating this mitigation measure needs to include a 100-foot defensible space buffer around structures in the proposed project and that this Coldstream Specific Plan Town of Truckee Final Environmental Impact Report March 2014 3.0-56 3.0 EVALUATION OF PROJECT MODIFICATIONS AND EIR COMMENTS AND RESPONSES defensible space is not allowed to be located on Donner Memorial State Park land. Mitigation measure MM 4.6.4 is consistent with the fire protection standards of the Town and the Truckee Fire Protection District and does not require a 100-foot defensible space buffer. The commenter is also referred to Response F-9 above. Response F-27: The commenter refers to Impact 4.7.2 of the Draft EIR related to stormwater runoff generation and surface water drainage patterns, and states that the entire development shall not drain water or have surface water runoff onto California State Parks property. The commenter is referred to mitigation measures MM 4.7.2a, MM 4.7.2b, and MM 4.7.3a of the Draft EIR pertaining to stormwater runoff and surface water drainage. These mitigation measures ensure that the proposed project shall be designed to result in drainage flow conditions below pre-project flow rates and would not discharge to the park. Response F-28: The commenter refers to mitigation measure MM 4.7.5b on page 4.7-39 of the Draft EIR regarding a new bridge crossing of Cold Creek and to their comment made related to page 3.0-39 of the Project Description. The commenter is referred to Response F-6. Response F-29: The commenter suggests the use of native plant species for seeding, planting, or revegetating disturbed areas adjacent to Donner Memorial State Park. The commenter is referred to Table 4-2, Restoration Plant Palette, in Chapter 4 of the Coldstream Specific Plan for a list of plant materials suitable for preservation, restoration, and enhancement activities that are proposed to be used within the project area. Response F-30: The commenter requests avoidance of using non-native invasive plants for all plant palettes. The commenter further requests that Russian olive (Elaeagnus angustifolia) and cranberry cotoneaster (Cotoneaster apiculatus) be removed from the Community Plant Palette due to their invasive nature and that this be included in mitigation measure MM 4.8.1g on page 4.8-61 of the Draft EIR. The indicated text in the DEIR was revised in the PRDEIR. The reader is referred to page 2.0-8 and 4.8-61 of the PRDEIR. Response F-31: The commenter suggests adding language to mitigation measure MM 4.8.2c of the Draft EIR to include additional measures and best management practices to avoid accidental transport and spread of invasive species and weeds. The indicated text in the DEIR was revised in the PRDEIR. The reader is referred to page 2.0-11 and 4.8-64 of the PRDEIR. Town of Truckee Coldstream Specific Plan March 2014 Final Environmental Impact Report 3.0-57 3.0 EVALUATION OF PROJECT MODIFICATIONS AND EIR COMMENTS AND RESPONSES Response F-32: The commenter provides a comment to item b. on page 3.7 of the Coldstream Specific Plan with regard to “snags” being provided throughout the project site. The comment is associated with the Specific Plan and not the Draft EIR. The comment is noted. Response F-33: The commenter recommends the Plant Communities and Habitat Types section under Subsection 4.8.1 Existing Setting of the Draft EIR only including plant and animal species that are local to the area to characterize plant communities and habitat types. Subsection 4.8.1 on page 4.8-1 (see Section 4.8, Biological and Natural Resources) of the Draft EIR properly describes the existing conditions of the project site, which have been altered over time by the extensive aggregate mining and reclamation activities occurring on the site. The environmental setting of the project site is properly described as required by Section 15125 of the CEQA Guidelines. Response F-34: The commenter states that black oak does not occur in the project vicinity. The reference to black oak acorns providing a forage resource essential for wildlife on page 4.8-17 of the Draft EIR references its existence in a range of mixed conifer forests that typically occurs at various elevations in the Sierra Nevada. Response F-35: The commenter states that while western scrub jay and American crow are identified as a native species that occur in ruderal communities, these species are not known to occur in the Town of Truckee. The reference on page 4.8-20 of the Draft EIR to native species occurring in ruderal habitat, including the western scrub jay and American crow, is describing the existing setting for species typically occurring in ruderal (disturbed) habitat areas. Response F-36: The commenter states that both kokanee salmon and mackinaw were introduced species, not native species as stated on page 4.8-21 of the Draft EIR. The commenter further states that mackinaw is strictly a lake species. The indicated text in the DEIR was revised in the PRDEIR. The reader is referred to page 4.8-21 of the PRDEIR. Response F-37: The commenter refers to Table 4.8-6 of the Draft EIR and states that while both the mountain yellow-legged frog and the Sierra Nevada yellow- legged frog are listed, they are not independently occurring species but rather a change in taxonomy. The commenter further states the mountain yellow-legged frog was split into the Sierra Nevada and the southern Sierra, of which only the Sierra Nevada has the potential to occur in the project area. Coldstream Specific Plan Town of Truckee Final Environmental Impact Report March 2014 3.0-58 3.0 EVALUATION OF PROJECT MODIFICATIONS AND EIR COMMENTS AND RESPONSES All references to mountain yellow-legged frog were stricken from the Draft EIR text, and Table 4.8-6 was amended as part of the PRDEIR. The reader is referred to Section 4.8, Biological and Natural Resources, of the PRDEIR. Response F-38: The commenter asks why the California spotted owl is addressed in the appendices, but not in the text of the Draft EIR. As stated in the Table B-1 in Appendix H, California spotted owl was not considered in the analyses due the following reasons: “Suitable habitat is not present within the Plan Area. There are no previously recorded occurrences within a ten mile radius of the Plan Area.” Response F-39: The commenter suggests that special-status bat species should appear under all vegetation types and that they may roost in various forest types and forage above the open water and wetlands. Table 4.8-6 of the Draft EIR was amended to address this comment in the PRDEIR. The reader is referred to page 4.8-31 of the PRDEIR. Response F-40: The commenter notes that the scientific name for osprey is misspelled on page 4.8-33 in the Draft EIR. The commenter further states the osprey described in the Draft EIR as foraging in June 2009 must have been an adult, as young hatch around the first of June, and that ospreys nesting in the vicinity of the proposed project regularly forage at the existing ponds on the project site. The indicated text in the Draft EIR was revised in the PRDEIR. The reader is referred to page 4.8-33 of the PRDEIR. Response F-41: The commenter notes that there is another reference on page 4.8-34 of the Draft EIR to a juvenile osprey observed foraging in June. The commenter is referred to Response F-40 above. Response F-42: The commenter references an informal consultation letter from the US Fish and Wildlife Service (USFWS) regarding Lahontan cutthroat trout that determined impacts to this fish are unlikely, but states the letter does not include potential for in-stream work associated with the proposed project. The commenter requests that an updated consultation with USFWS be completed and that it also address the potential for fuel entering the water system, as described on page 4.8-51 of the Draft EIR under the discussion of yellow-legged frog. Prior to beginning restoration work in Cold Creek, the applicant will coordinate with the U.S. Army Corps of Engineers and the U.S. Fish & Wildlife Service to determine whether a new or updated Section 7 consultation is required to address potential impacts to Lahontan cutthroat trout as a result of those restoration activities. If the agencies determine that such consultation is required, the applicant will comply with any conditions which result from that consultation. The indicated text in the Draft EIR was revised in the PRDEIR. The reader is referred to page 4.8-51 of the PRDEIR. The commenter is also referred to Section 3.3, Town of Truckee Coldstream Specific Plan March 2014 Final Environmental Impact Report 3.0-59 3.0 EVALUATION OF PROJECT MODIFICATIONS AND EIR COMMENTS AND RESPONSES Environmental Effects of Modifications to the Proposed Project, in this document that identifies that mitigation measures in Draft EIR Sections 4.7, Hydrology and Water Quality, and 4.8, Natural and Biological Resources, specifically address and mitigate impacts associated with restoration work on Cold Creek and Donner Creek. Response F-43: The commenter requests additional discussion in the Draft EIR related to impacts on the yellow-legged frog from proposed restoration work, as the discussion regarding minimal direct impacts to the creeks on page 4.8-51 is insufficient. The commenter provides no addition data to support the conjecture that analysis is insufficient. The commenter is referred to Section 3.3, Environmental Effects of Modifications to the Proposed Project, in this document that identifies that mitigation measures in Draft EIR Sections 4.7, Hydrology and Water Quality, and 4.8, Natural and Biological Resources, specifically address and mitigate impacts associated restoration work on Cold Creek and Donner Creek. The indicated text in the Draft EIR was revised in the PRDEIR. The reader is referred to page 4.8-51 of the PRDEIR. Response F-44: The commenter requests that the bald eagle nest minimum buffer described on page 4.8-51 of the Draft EIR be increased from 500 feet to 1,500 feet. The appropriate nest avoidance criteria are dependent on specifics of the nesting circumstance and include the physical context of the nest location, the species involved, the timing of the impact, the type of impact, and timing of the impact relative to the reproduction cycle. Specific active nest set backs are provided for guidance. As identified in mitigation measure MM 4.8.1c, if active nests are found, the California Department of Fish and Game (CDFG) and/or USFWS shall be notified and these agencies will determine the avoidance conditions, including buffer, that are necessary specific to the active nesting circumstances. Response F-45: The commenter requests that surveys for the absence of active raptor nests described in mitigation measure MM 4.8.1c on page 4.8-59 of the Draft EIR be increased from 500 feet outside of the project site boundaries to 1,500 feet. The commenter is referred to Response F-44 above. Response F-46: The commenter believes the maximum allowable structure height for the proposed MUC, VGR, and VSL uses adjacent to Donner Memorial State Park will cause substantial degradation of the visual character as viewed by park visitors. The commenter requests that structures on the boundary to the park be limited to one story in height for the VSL and REC zoning districts and two stories in height for the MUC and VGR zoning districts. The commenter does not provide any technical analysis related to their concern about substantial visual degradation of the site’s visual character. The commenter is referred to discussion on pages 4.10-15 through -27 and Figure 4.10-4d of the Draft EIR related to substantial Coldstream Specific Plan Town of Truckee Final Environmental Impact Report March 2014 3.0-60 3.0 EVALUATION OF PROJECT MODIFICATIONS AND EIR COMMENTS AND RESPONSES degradation of visual character. The Draft EIR concludes that views of the project site from surrounding existing uses would be adequately screened by existing and proposed vegetation, walls and/or fences, naturally vegetated setbacks, and landscaped buffers. In addition, the proposed roadway improvements, landscaping, and undergrounding of existing telephone and utility poles could result in beneficial changes to existing views from the surrounding uses. Furthermore, the project site’s natural features would be restored and enhanced to create significant visual amenities throughout the site that better represent the surrounding natural environment of the region. Existing trees would be preserved where feasible and some would be replaced through implementation of mitigation measure MM 4.8.7b. Finally, implementation of the extensive design guidelines provided in the proposed Coldstream Specific Plan (see Chapters 3 and 4 of the Specific Plan) and the standards contained in the Town of Truckee Development Code would ensure that the proposed development would meet the Town’s high visual and architectural standards. The commenter is referred to Section 3.2, Modifications to Project Characteristics, of this document that identifies modification of the project design since release of the Draft EIR. The now proposed Options A and B consist of reduced development potential as compared to the originally proposed Coldstream Specific Plan. Response F-47: The commenter requests the use of colors that blend in with the natural environment to disguise all buildings and structures constructed adjacent to Donner Memorial State Park, and references colors listed on page 4.22 in the Coldstream Specific Plan document. The comment refers to the design of the proposed project and is not related to the adequacy of the Draft EIR. No further comment is required. Response F-48: The commenter references the post-project views on Figures 4.10-4a, -4b, and -4c and requests that the proposed project retain existing evergreen conifer trees where possible and plant more native evergreen trees than native deciduous trees to provide year-round visual screening of the project. The comment refers to the design of the proposed project. This comment is noted. Response F-49: The commenter references Section 3.6, Lighting Program, of the Coldstream Specific Plan document and supports efforts to protect the night sky and decrease the potential for lighting impacts to Donner Memorial State Park. The comment on Section 3.6 of the Specific Plan is noted. Response F-50: The commenter references pages 3.42, 3.53, and 3.55 of the Coldstream Specific Plan document related to residential exterior lighting and questions the rationale of having residential porch lights automatically Town of Truckee Coldstream Specific Plan March 2014 Final Environmental Impact Report 3.0-61 3.0 EVALUATION OF PROJECT MODIFICATIONS AND EIR COMMENTS AND RESPONSES turn on and off at predetermined times, as this seems contrary to the lighting plan and the desire to decrease light pollution. The comment on the exterior lighting provisions of the Specific Plan is noted. Project nighttime lighting impacts are addressed in the Draft EIR on pages 4.10-27 through -29 and include consideration of Town Development Code lighting standards. Response F-51: The commenter references page 3.58 of the Coldstream Specific Plan document and questions whether the Forest Residential Zone lighting will be similar to the automatic lighting scheme as defined in other residential zones. The comment on the exterior lighting provisions of the Specific Plan is noted. Project nighttime lighting impacts are addressed in the Draft EIR on pages 4.10-27 through -29 and include consideration of Town Development Code lighting standards. Response F-52: The commenter requests that the proposed project minimize the potential reflection/glare from windows, skylights, photovoltaic panels, etc., that would impact the viewshed from higher elevations in Coldstream Canyon at Donner Memorial State Park. Project nighttime lighting and daytime glare impacts are addressed in the Draft EIR on pages 4.10-27 through -29 and include consideration of Town Development Code lighting standards. Response F-53: The commenter references mitigation measure MM 4.11.3.2 on page 4.11-15 of the Draft EIR and supports working cooperatively with the Town of Truckee on finalization of connection points for the proposed project’s trails and signage notifying trail users when entering State Park property. The commenter further requests that the California Department of Parks and Recreation be removed from the enforcement/monitoring obligation under this mitigation measure due to lack of funding to fulfill this obligation. The commenter is acknowledging support of mitigation measure MM 4.11.3.2 being required as part of the proposed project. The indicated text in the Draft EIR has been revised. The reader is referred to Section 4.0, Minor Revisions to the EIR. Response F-54: The commenter references mitigation measure MM 4.11.3.2 on page 4.11-15 of the Draft EIR and is concerned that users of the Truckee Legacy Trail Recreational Segment would park within the boundaries of the proposed project, thereby not paying daily vehicle parking fees at Donner Memorial State Park’s parking areas, which generate revenue that support the operations and maintenance of the park’s facilities. The comment refers to the design of the proposed project and potential economic impacts on the State associated with trail connectivity from the proposed project to Donner Memorial State Park. Economic impacts are not considered physical effects on the environment that subject to Coldstream Specific Plan Town of Truckee Final Environmental Impact Report March 2014 3.0-62 3.0 EVALUATION OF PROJECT MODIFICATIONS AND EIR COMMENTS AND RESPONSES consideration under CEQA and thus are not considered in the Draft EIR (CEQA Guidelines Section 15131). Response F-55: The commenter indicates that the Town of Truckee could contribute Quimby Act funding generated by the proposed project to the State to help fund a portion of the maintenance costs of Donner Memorial State Park to offset increased use from the proposed project. The commenter further states that this funding could provide the monetary support for enforcement and monitoring by the State under mitigation measure MM 4.11.3.2. Economic impacts are not considered physical effects on the environment that subject to consideration under CEQA and thus are not considered in the Draft EIR (CEQA Guidelines Section 15131). Response F-56: The commenter suggests that the proposed project’s common areas include playground areas and equipment for the youth of the project’s future residents to use. The commenter further states the proposed project should allow recreational access to the ponds onsite, thereby reducing the potential to increase use and resource damage at the Donner Memorial State Park pond located south of the proposed project. The proposed project provides a Recreation zoning district that includes 3.8 to 6.5 acres (depending on which project option design is approved) of future recreation uses for residents of the proposed project, and trails connecting to and located around the pond features as depicted on Figures 3.0-1 and 3.0-2 for Options A and B. The recreational amenities included as part of the proposed project will reduce the potential increase use and resource damage at Donner Memorial State Park. Response F-57: The commenter states that they are conceptually in favor of Project Alternative 4 – Reduced Development Potential; however, they request additional information regarding the buildout of this alternative because the Draft EIR description on pages 6.0-54 through -61 lacks details regarding the density and type of housing that would occupy the MUC zoning district and regarding changes in traffic circulation. The intent of Project Alternative 4 is to provide information regarding a reduction of impacts from the proposed project associated with reduced development. Providing the specific location where residential housing units would be reduced is not a required detail for evaluation of the environmental impacts of this alternative. As discussed under Alternative 4 in the Draft EIR, the proposed project would reduce the number of residential units by 85 units and eliminate 70,000 square feet of commercial uses. This reduction would minimize impacts to wetlands as well as avoid project traffic impacts to the I-80 Westbound Ramps/Donner Pass Road intersection. Traffic circulation patterns would remain the same as shown on Draft EIR Figure 6.0-6, with the exception of providing emergency access only to Deerfield Drive. The commenter is also referred to Section 3.2, Modifications to Project Characteristics, of this document that identifies modification of the project Town of Truckee Coldstream Specific Plan March 2014 Final Environmental Impact Report 3.0-63 3.0 EVALUATION OF PROJECT MODIFICATIONS AND EIR COMMENTS AND RESPONSES design since release of the Draft EIR. The now proposed Options A and B consist of reduced development potential as compared to the originally proposed Coldstream Specific Plan. Response F-58: The commenter states that if no further information is provided for Alternative 4 of the Draft EIR and the MUC area becomes residential housing, the California State Park’s previous comments related to the VGR and VSL zoning districts adjacent to Donner Memorial State Park would apply. Residential housing is proposed as an encouraged use in the MUC zoning district of the Coldstream Specific Plan. The commenter is referred to Responses F-13, F-18, and F-46 above regarding concerns associated with residential uses adjacent to Donner Memorial State Park. The commenter is also referred to Section 3.2, Modifications to Project Characteristics, of this document that identifies modification of the project design since release of the Draft EIR. The now proposed Options A and B consist of reduced development potential as compared to the originally proposed Coldstream Specific Plan.

The indicated text in the Draft EIR has been revised. The reader is referred to Section 4.0, Minor Revisions to the EIR. Response G-2: The commenter states that the North Donner Pump Station should be referred to as Lift Station 1A on page 4.12-10 of the Draft EIR. The indicated text in the Draft EIR has been revised. The reader is referred to Section 4.0, Minor Revisions to the EIR. Response G-3: The commenter states that the Deerfield Pump Station should be referred to as Sub O on page 4.12-10 of the EIR. The indicated text in the Draft EIR has been revised. The reader is referred to Section 4.0, Minor Revisions to the EIR. Response G-4: The commenter states that Sub O discharges directly into the 10-inch force main, not into the 12-inch gravity main as indicated on page 4.12-10 of the Draft EIR. The indicated text in the Draft EIR has been revised. The reader is referred to Section 4.0, Minor Revisions to the EIR. Response G-5: The commenter states that the gravity main to the south of Lift Station 1A has a 6-inch diameter, not an 8-inch diameter. The indicated text in the Draft EIR has been revised. The reader is referred to Section 4.0, Minor Revisions to the EIR. Response G-6: The commenter states that there cannot be any connection of a gravity main directly into the 10-inch force main. It is not clear from the commenter’s comment where the Draft EIR indicates a gravity main is called out as connecting directly into the 10- inch force main. The comment is noted. Response G-7: The commenter states that for approximately 700 feet underneath Cold Stream, the 10-inch force main is split into two parallel pipes of 8-inch and 12-inch diameter. The indicated text in the Draft EIR has been revised. The reader is referred to Section 4.0, Minor Revisions to the EIR. Response G-8: The commenter indicates there are five bypass ports located on the force main as it passes through the project site and that all bypass ports must be protected. Town of Truckee Coldstream Specific Plan March 2014 Final Environmental Impact Report 3.0-67 3.0 EVALUATION OF PROJECT MODIFICATIONS AND EIR COMMENTS AND RESPONSES The comment does not pertain to the adequacy of the Draft EIR. It is assumed that the requirement for protecting existing bypass ports associated with sewer facilities serving the project site will be protected, and this can be made a requirement on future underground improvement plans during the plan check process. Response G-9: The commenter states that the proposed realignment of the 10-inch force main from Lift Station 1A may create the need to upgrade the pump and generator at Lift Station 1A, and that the current diesel-powered generator at Lift Station 1A operates under a permit from the Air Resources Board. The comment does not pertain to the adequacy of the Draft EIR. It is assumed that the potential requirement for upgrading the pump and generator system at Lift Station 1A can be made a requirement on future underground improvement plans during the plan check process. Response G-10: The commenter references the discussion on page 4.12-11 of the Draft EIR and states that the TSD uses a fixture count to estimate commercial flows, but the proposed flow from the commercial units of 0.08 gallons per day per square foot is not a value TSD utilizes. The comment’s statements regarding this flow rate is correct. The Draft EIR utilized this flow rate for analysis given that the number of fixtures in the commercial development is not known at this time. Response G-11: The commenter indicates that on page 4.12-14 of the Draft EIR, the current TSD Code should reference Ordinance 1-2008. The indicated text in the Draft EIR has been revised. The reader is referred to Section 4.0, Minor Revisions to the EIR. Response G-12: The commenter references Figure 3.0-17 and states the sewer pipeline shown in the southwest portion of the map as an 8-inch pipe is only 6 inches in diameter. The commenter also indicates that if an 8-inch pipe is required, the 6-inch pipe will have to be upgraded by the project developer. Draft EIR Figure 3.0-17 has been revised to reflect that the existing sewer pipe in this location is 6 inches in diameter. The reader is referred to Section 4.0, Minor Revisions to the EIR. Response G-13: The commenter references Figure 3.0-17. The commenter states that the map indicates there will be a connection to the existing 10-inch force main on the northern portion of the project site and that no connection can be made to the 10-inch force main. Figure 3.0-17 uses the term “connect to existing/begin realignment,” indicating the existing line will begin realignment at this location. This does not include a new connection, but simply realigns the existing 10-inch force main through the proposed project site to be located under the future roadway alignment in this area of the project site. In addition, sewer Coldstream Specific Plan Town of Truckee Final Environmental Impact Report March 2014 3.0-68 3.0 EVALUATION OF PROJECT MODIFICATIONS AND EIR COMMENTS AND RESPONSES service improvement plans will be prepared and submitted to the Truckee Sanitation District for review and approval, along with payment of appropriate fees, prior to any physical sewer improvements being installed for the proposed project. Response G-14: The commenter references Figure 3.0-17 and states that the proposed new lift station at the northeast portion of the project site will require a new force main to be installed along Deerfield Drive to the beginning of the 12-inch gravity main. Based on information provided by the proposed project’s civil engineer, a force main would be designed and installed from the new lift station to a point of connection with the existing 12-inch gravity main in Deerfield Drive located approximately 400 feet east of the eastern project site boundary. In addition, sewer service improvement plans will be prepared and submitted to the Truckee Sanitation District for review and approval, along with payment of appropriate fees, prior to any physical sewer improvements being installed for the proposed project. Response G-15: The commenter references Figure 3.0-17 and states that it is unclear what is meant by the “end realignment of 10-inch sewer line” in the note in the northeast portion of the map. The “end of realignment of 10-inch sewer line” note refers to the potential need to realign the existing sewer line within the proposed project site boundaries. Response G-16: The commenter references Figure 3.0-17 and states that any relocated sewer facilities will need to be placed within sanitary sewer or public utility easements. The comment does not pertain to the adequacy of the Draft EIR. It is assumed that the potential requirement for placing relocated sewer facilities within sanitary sewer or public utility easements can be made a requirement on future underground improvement plans during the plan check process. Town of Truckee Coldstream Specific Plan March 2014 Final Environmental Impact Report 3.0-69 3.0 EVALUATION OF PROJECT MODIFICATIONS AND EIR COMMENTS AND RESPONSES Coldstream Specific Plan Town of Truckee Final Environmental Impact Report March 2014 3.0-70 3.0 EVALUATION OF PROJECT MODIFICATIONS AND EIR COMMENTS AND RESPONSES Letter H Ken Chiang, P.E., California Public Utilities Commission Response H-1: The commenter describes the Commission’s jurisdiction over highway-rail crossings and states that the Commission has received the PRDEIR. The Town acknowledges the Commission’s jurisdiction over highway-rail crossings in the project area. Response H-2: The commenter states that the project area includes active railroad tracks. The commenter further recommends that the Town amend the Specific Plan to consider the safety of the rail corridor including pedestrian/bike circulation patterns and compliance with the Americans with Disabilities Act. The commenter provides suggested mitigation measures including the planning for grade separations for major thoroughfares, improvements to existing at-grade crossings, and the use of appropriate barriers to limit access of trespassers onto the railroad right- of-way (ROW). Page 3.0-1 of the DEIR, Surrounding Uses, states that the Union Pacific Railroad (UPRR) is located along the southern boundary of the project site. As described in DEIR Section 4.2, Transportation and Circulation, and as shown on DEIR Figure 3.0-29, the Specific Plan provides for a safe and efficient circulation plan that considers the existing circulation network including roadways, trails and the UPRR line. The site would be accessed from the north via Donner Pass Road and Deerfield Drive. All project traffic traveling south of the site would be directed to SR 89 which currently has a grade-separated crossing of the UPRR line. No new railroad crossings are proposed and no increase in traffic would occur at an existing at-grade crossing. Furthermore, as shown on Figure 3.0-16 of the DEIR, existing and proposed trails do not cross the UPRR line. Proposed residential and commercial uses would be separated from the UPRR line by open space limiting access to the railroad ROW.

The commenter further states that the California State Parks owns and operates Donner Memorial State Park adjacent to the proposed project site and owns another parcel adjacent to the project that is isolated from access by Cold Creek and the Stonebridge properties. The comment is noted. Response I-2: The commenter states that archaeological resource CA-NEV-13/H is listed on the National Register of Historic Places, not Donner Memorial State Park as is stated in the PRDEIR. The indicated text on Page 4.9-4 of the PRDEIR has been revised. The reader is referred to Section 4.0, Minor Revisions to the EIR. Response I-3: The commenter provides a description of archaeological resource CA- NEV-13/H. The comment is noted. Archaeological resource CA-NEV-13/H is not located within the project site and would not be impacted by project implementation. Therefore, a detailed description of this resource is not warranted in the PRDEIR. Response I-4: The commenter states that one additional archaeological resource, Coldstream-01-2007, is located southwest of the project site near the boundary of Donner Memorial State Park and the adjacent Caltrans property. The comment is noted. Archaeological resource Coldstream-01-2007 is not located within the project site and would not be impacted by project implementation. Therefore, the resource is not discussed in the PRDEIR. Response I-5: The commenter requests a copy of the Archaeological Inventory Report prepared for the proposed project by Genesis Society. The Archaeological Inventory Report prepared for the proposed project is a confidential document. All pertinent information from the report was provided in Section 4.8 of the DEIR and PRDEIR.

Section 4.2, Traffic and Circulation, of the Draft EIR addresses all options in detail in regards to traffic impacts. The commenter is also referred to Section 3.2, Modifications to Project Characteristics, of this document that identifies modification of the project design since release of the Draft EIR. The now proposed Options A and B consist of reduced development potential as compared to the originally proposed Coldstream Specific Plan (see Figures 3.0-1 and 3.0-2). Both options reduce the extent of development on the site. Option A would retain the open roadway connection to Deerfield Drive, but would modify the site design to provide a circuitous roadway system to discourage vehicle trips that pass through the site to access Deerfield Drive and State Route 89 south of Interstate 80. The reduced development intensity and site design would reduce the average daily traffic one-way trips on Deerfield Drive east of the project site to 950 trips (as compared to the originally proposed Coldstream Specific Plan that would generate 2,340 trips). Option B would consist of an emergency-only access to Deerfield Drive and the development of a neighborhood park at this location. Response 1-2: The commenter states that an open connection to Deerfield Drive would make their front yard as noisy as their back yard (noisy due to I-80). Section 4.3, Noise, of the Draft EIR provides a noise analysis for the proposed project and includes a series of mitigation measures that would ensure that noise impacts from construction and operational sources are less than significant under the proposed project. The commenter is also referred to Section 3.3, Environmental Effects of Modifications to the Proposed Project, of this document that identifies Option A and B would result in reduced development potential and its impacts in relation to the originally proposed Coldstream Specific Plan. Response 1-3: The commenter expresses concern about use on Deerfield Drive when I-80 gets congestion, leading to congestion on Donner Pass Road and Deerfield Drive. Section 4.2, Transportation and Circulation, of the Draft EIR provides a traffic analysis for the proposed project and includes a series of mitigation measures that would ensure traffic impacts, including those to local roadways, are less than significant under the proposed project. The revised Traffic Impact Analysis prepared for the newly proposed Options A and B resulted in similar conclusions. The Draft EIR identified a significant and unavoidable impact regarding General Plan Circulation Element consistency, but it was only found to be significant and unavoidable for Options 2, 3, and 4. The newly proposed Option B would also result in a significant and unavoidable impact regarding General Plan Circulation Element consistency, as this option does not provide a through roadway Town of Truckee Coldstream Specific Plan March 2014 Final Environmental Impact Report 3.0-77 3.0 EVALUATION OF PROJECT MODIFICATIONS AND EIR COMMENTS AND RESPONSES connection to Deerfield Drive east of the project site. The commenter is also referred to Response 1-1 above. Response 1-4: The commenter states that pedestrian and bicycle access would be a sufficient connection between the neighborhoods and would allow for safer, quieter streets in an area already noisy from vehicle use. The environmental effects of the construction and operation of pedestrian and bicycle trails have been addressed in the technical sections of the Draft EIR, including a Class III bike route along Deerfield Drive connecting this existing neighborhood with the proposed project.

Smith Response 6-1: The commenter requests that Option One not be considered in the Town’s final decision. The commenter is referred to Section 3.2, Modifications to Project Characteristics, of this document that identifies modification of the project design since release of the Draft EIR. The now proposed Options A and B consist of reduced development potential as compared to the originally proposed Coldstream Specific Plan (see Figures 3.0-1 and 3.0-2). Both options reduce the extent of development on the site. Option A would retain the open roadway connection to Deerfield Drive, but would modify the site design to provide a circuitous roadway system to discourage vehicle trips that pass through the site to access Deerfield Drive and State Route 89 south of Interstate 80. The reduced development intensity and site design would reduce the average daily traffic one-way trips on Deerfield Drive east of the project site to 950 trips (as compared to the originally proposed Coldstream Specific Plan that would generate 2,340 trips). Option B would consist of an emergency-only access to Deerfield Drive and the development of a neighborhood park at this location. Response 6-2: The commenter asks that an option where Deerfield Drive is kept closed be considered. The commenter is referred to Response 6-1 above. Response 6-3: The commenter states that the increase in traffic associated with the proposed project does not comply with the General Plan standards. The Draft EIR identified a significant and unavoidable impact regarding General Plan Circulation Element consistency, but it was only found to be significant and unavoidable for Options 2, 3, and 4. The newly proposed Option B would also result in a significant and unavoidable impact regarding General Plan Circulation Element consistency, as this option does not provide a through roadway connection to Deerfield Drive east of the project site. The physical effects of connecting Deerfield Drive with the project site as a through roadway have been analyzed in the various technical sections of the Draft EIR and the revised Traffic Impact Analysis prepared for Options A and B, and no new significant environmental effects were identified. Response 6-4: The commenter states that potentially significant roadway noise on Deerfield Drive is proposed to be mitigated in the Draft EIR with a rubberized asphalt surface on the roadway. Comment noted. Response 6-5: The commenter states that potentially significant impacts regarding hazards to pedestrians and trail users are proposed to be mitigated using sidewalks.

This comment is noted. The commenter is referred to Section 3.2, Modifications to Project Characteristics, of this document that identifies modification of the project design since release of the Draft EIR. The now proposed Options A and B consist of reduced development potential as compared to the originally proposed Coldstream Specific Plan (see Figures 3.0-1 and 3.0-2). Both options reduce the extent of development on the site. Option A would retain the open roadway connection to Deerfield Drive, but would modify the site design to provide a circuitous roadway system to discourage vehicle trips that pass through the site to access Deerfield Drive and State Route 89 south of Interstate 80. The reduced development intensity and site design would reduce the average daily traffic one-way trips on Deerfield Drive east of the project site to 950 trips (as compared to the originally proposed Coldstream Specific Plan that would generate 2,340 trips). Option B would consist of an emergency-only access to Deerfield Drive and the development of a neighborhood park at this location. Response 7-2: The commenter states that the economic downturn and increased cost of fuel should be considered in the transportation study for the project. Economic impacts are not considered physical effects on the environment that subject to consideration under CEQA and thus are not considered in the Draft EIR (CEQA Guidelines Section 15131). Response 7-3: The commenter asks why the project is proposing large commercial space when more suitable space exists in the downtown core area. The commenter question is noted. The commenter is referred to Response 7-1 regarding modifications to the project since release of the Draft EIR that includes a reduction in the retail/commercial square footage. Response 7-4: The commenter quotes the project’s Economic Impact Analysis in regard to the proposed project’s ability to support a modest amount of retail demand, even though projections indicate insufficient demand to support all of Truckee’s approved retail projects by 2020. The commenter’s input on the project’s economic analysis is noted. The commenter is referred to Response 7-1 regarding modifications to the project since release of the Draft EIR that includes a reduction in the retail/commercial square footage. Response 7-5: The commenter asks why the project is proposing lodging development when there are already struggling hotel rooms within the town and other lodging units that are already approved. Town of Truckee Coldstream Specific Plan March 2014 Final Environmental Impact Report 3.0-95 3.0 EVALUATION OF PROJECT MODIFICATIONS AND EIR COMMENTS AND RESPONSES The comment’s questions on lodging development are noted. The commenter question is noted. The commenter is referred to Response 7-1 regarding modifications to the project since release of the Draft EIR that includes a reduction in the retail/commercial square footage. Response 7-6: The commenter states that Alternative 4 provides a better, less dense housing plan. The commenter’s support of Alternative 4 is noted. Response 7-7: The commenter states that the Lakeside units should be eliminated from the project, as the Town of Truckee already has a sufficient amount of high-end housing opportunities. The comment input on the project design is noted. The commenter is referred to Response 7-1 regarding modifications to the project since release of the Draft EIR. Response 7-8: The commenter states that the proposed project would be subject to constant loud highway noise near houses and further states that the lakeside area should be used as recreation space for the development. Exposure to traffic noise from Interstate 80 is addressed in Draft EIR Section 4.3, Noise. As shown in Draft EIR Table 4.3-2, ambient noise measurements of the project site generally showed that on-site noise levels are within the Town’s noise standards. However, mitigation measure MM 4.3.3 and MM 4.3.4 would require noise attenuation features for the project. Regarding access to the lakeside area for recreational use, the commenter is referred to Figure 3.0-1 and 3.0-2 for Options A and B depicting the proposed trail system, including trails around the entire lake frontage for recreational purposes. Response 7-9: The commenter states that using Deerfield Drive as a through street would encourage additional use on the road and is inconsistent with the General Plan policy regarding accommodating and encouraging alternate forms of transportation. Appendix B of the Draft EIR presents an analysis of the project’s consistency with the Town of Truckee 2025 General Plan. This analysis found that the project, with the mitigation proposed in the Draft EIR, would be consistent with all applicable General Plan policies. The Draft EIR identified a significant and unavoidable impact regarding General Plan Circulation Element consistency, but it was only found to be significant and unavoidable for Options 2, 3, and 4. The newly proposed Option B would also result in a significant and unavoidable impact regarding General Plan Circulation Element consistency, as this option does not provide a through roadway connection to Deerfield Drive east of the project site. Response 7-10: The commenter states that the project should consider a multi-use trail and bikeway system rather than open Deerfield Drive. Coldstream Specific Plan Town of Truckee Final Environmental Impact Report March 2014 3.0-96 3.0 EVALUATION OF PROJECT MODIFICATIONS AND EIR COMMENTS AND RESPONSES The proposed project (as modified by Options A and B) include trail connections to Deerfield Drive (see Figures 3.0-1 and 3.0-2) Response 7-11: The commenter restates their support for Alternative 4 and their opposition to using Deerfield Drive as a through street.

Both options reduce the extent of development on the site. Option A would retain the open roadway connection to Deerfield Drive, but would modify the site design to provide a circuitous roadway system to discourage vehicle trips that pass through the site to access Deerfield Drive and State Route 89 south of Interstate 80. The reduced development intensity and site design would reduce the average daily traffic one-way trips on Deerfield Drive east of the project site to 950 trips (as compared to the originally proposed Coldstream Specific Plan that would generate 2,340 trips). Option B would consist of an emergency-only access to Deerfield Drive and the development of a neighborhood park at this location. The Draft EIR identified a significant and unavoidable impact regarding General Plan Circulation Element consistency, but it was only found to be significant and unavoidable for Options 2, 3, and 4 (see also the General Plan consistency analysis provided in Appendix B of the Draft EIR). The newly proposed Option B would also result in a significant and unavoidable impact regarding General Plan Circulation Element consistency, as this option does not provide a through roadway connection to Deerfield Drive east of the project site. The physical effects of connecting Deerfield Drive with the project site as a through roadway have been analyzed in the various technical sections of the Draft EIR and the revised Traffic Impact Analysis prepared for Options A and B, and no new significant environmental effects were identified. Response 17-2: The commenter states that they do not want a through street on Deerfield Drive, as it will increase noise and traffic hazards. Draft EIR Section 4.2, Traffic and Circulation, does not identify any traffic operational issues associated with the connection to Deerfield Drive. However, it does identify potential safety concerns on Draft EIR pages 4.2- 70 and -71 and identifies mitigation measures MM 4.2.10b through d to address this impact. Noise impacts associated with the proposed Deerfield connection were addressed on Draft EIR pages 4.3-25 and -26 and include the implementation of mitigation measure MM 4.3.5 to reduce the increase in traffic noise with the use of rubberized or open- gap asphalt. The commenter is also referred to Response 17-1 regarding modifications to the project since release of the Draft EIR.

Morris Response 19-1: The commenter states that they are in support of the proposed project, with the exception of converting Deerfield Drive to a through roadway. The commenter further states that other Deerfield Drive residents and the developer oppose the through road design and that Town Planning staff appear to be the only people pushing for a through road design. This comment is noted. The commenter is referred to Section 3.2, Modifications to Project Characteristics, of this document that identifies modification of the project design since release of the Draft EIR. The now proposed Options A and B consist of reduced development potential as compared to the originally proposed Coldstream Specific Plan (see Figures 3.0-1 and 3.0-2).

Option B would consist of an emergency-only access to Deerfield Drive and the development of a neighborhood park at this location. Response 19-2: The commenter states that the project goes against the Truckee General Plan, as it requires an amendment to the General Plan. The Draft EIR identified a significant and unavoidable impact regarding General Plan Circulation Element consistency, but it was only found to be significant and unavoidable for Options 2, 3, and 4 (see also the General Plan consistency analysis provided in Appendix B of the Draft EIR). The newly proposed Option B would also result in a significant and unavoidable impact regarding General Plan Circulation Element consistency, as this option does not provide a through roadway connection to Deerfield Drive east of the project site. The physical effects of connecting Deerfield Drive with the project site as a through roadway have been analyzed in the various technical sections of the Draft EIR and the revised Traffic Impact Analysis prepared for Options A and B, and no new significant environmental effects were identified. Response 19-3: The commenter states that the quiet nature of Deerfield Drive would be destroyed by the project. Noise impacts associated with the proposed Deerfield connection are addressed on Draft EIR pages 4.3-25 and -26 and include the implementation of mitigation measure MM 4.3.5 to reduce the increase in traffic noise with the use of rubberized or open-gap asphalt. Response 19-4: The commenter states that converting Deerfield Drive to a through road would be a major impact to all properties along Deerfield Drive. Coldstream Specific Plan Town of Truckee Final Environmental Impact Report March 2014 3.0-124 3.0 EVALUATION OF PROJECT MODIFICATIONS AND EIR COMMENTS AND RESPONSES This comment is noted. The commenter is referred to Response 19-1 regarding modifications to the project since release of the Draft EIR. Response 19-5: The commenter states that property values along Deerfield Drive would decrease due to the street being turned into a through road. This comment is noted. The commenter is referred to Response 19-1 regarding modifications to the project since release of the Draft EIR. Economic impacts are not considered physical effects on the environment that subject to consideration under CEQA and thus are not considered in the Draft EIR (CEQA Guidelines Section 15131). Response 19-6: The commenter states that I-80 runs parallel within 100 yards of Deerfield Drive and is an existing and significantly better roadway for accessing Donner Lake and Coldstream. This comment is noted. The project’s impacts on traffic are addressed in Draft EIR Section 4.2, Traffic and Circulation, as well as in Appendix B of this document for Options A and B (referred to as “Options 1 and 2”). Response 19-7: The commenter states that the Draft EIR does not analyze commercial trucks traveling between the existing Crossroads Center and the commercial area to be developed by Coldstream. The commenter is referred to Response 19-1 above. As shown under the newly proposed Option A, the Deerfield Drive connection is proposed to be reconfigured into a more circuitous route, with the intention of discouraging through traffic between Deerfield Drive east of the project site and the proposed project. Utilizing I-80 between the SR 89 and Donner Pass Road interchanges provides a more direct and feasible route for commercial truck traffic traveling between the Crossroads Commercial Center and the proposed project’s commercial area. In addition, the re- designation of Deerfield Drive to a “minor collector” will still result in this roadway having travel restrictions to commercial vehicles on Deerfield Drive due to applicable weight limits of a maximum of 8 tons for this roadway designation and signage directing drivers of commercial vehicles away from Deerfield Drive due to the residential nature of this roadway. Response 19-8: The commenter suggests that allowing Deerfield Drive to remain a dead- end street will encourage bicyclists and pedestrians to use the trails to travel back and forth between the existing residential area on Deerfield Drive and the proposed project, thus minimizing vehicle trips between the neighborhoods and commercial areas on either end. This comment is noted. As noted in Response 19-1, Option B would provide a pedestrian and bicycle connection while keeping the connection to Deerfield closed to vehicle traffic. Response 19-9: The commenter states that Alternatives 2, 3, and 4 would be preferable to the proposed project, as they maintain the residential integrity of Deerfield Drive by having a road connection for emergency access only.

The commenter is referred to Section 3.2, Modifications to Project Characteristics, of this document that identifies modification of the project design since release of the Draft EIR. The now proposed Options A and B consist of reduced development potential as compared to the originally proposed Coldstream Specific Plan (see Figures 3.0-1 and 3.0-2).

The physical effects of connecting Deerfield Drive with the project site as a through roadway have been analyzed in the various technical sections of the Draft EIR and the revised Traffic Impact Analysis prepared for Options A and B, and no new significant environmental effects were identified. Response 20-2: The commenter states that the Draft EIR fails to adequately address safety, noise, and health issues and that changing Deerfield Drive to a collector road is inconsistent with the General Plan. Draft EIR Section 4.2, Traffic and Circulation, does not identify any traffic operational issues associated with the connection to Deerfield Drive. However, it does identify potential safety concerns on Draft EIR pages 4.2- 70 and -71 and identifies mitigation measures MM 4.2.10b through d to address this impact. Noise impacts associated with the proposed Deerfield connection are addressed on Draft EIR pages 4.3-25 and -26 and include the implementation of mitigation measure MM 4.3.5 to reduce the increase in traffic noise with the use of rubberized or open- gap asphalt. The commenter is referred to Response 20-1 regarding General Plan consistency concerns. Response 20-3: The commenter states that the rubberized asphalt surface proposed to mitigate noise impacts resulting from additional traffic on Deerfield Drive would still result in a 14.6 percent increase in noise levels. Coldstream Specific Plan Town of Truckee Final Environmental Impact Report March 2014 3.0-130 3.0 EVALUATION OF PROJECT MODIFICATIONS AND EIR COMMENTS AND RESPONSES The commenter misinterprets the Draft EIR noise analysis. As noted on Draft EIR page 4.3-3, exposure to noise is based on changes in decibel levels. A 3 dBA change in noise levels is considered just perceivable by the human ear. Draft EIR page 4.3-25 identifies that the change in traffic conditions on Deerfield Drive would result in a 6 dBA increase in traffic noise levels and implementation of mitigation measure MM 4.3.5 would reduce this increase in noise level of 4 dBA. Thus, mitigation measure MM 4.3.5 would reduce project traffic noise levels below human ear perception levels. The commenter is also referred to Response 20-1 regarding modifications to the project design since release of the Draft EIR. Response 20-4: The commenter states that adding sidewalks to the proposed project would require tree removal, which would change the residential character of Deerfield Drive and reduce property values. As identified on Draft EIR page 4.2-71, potential tree removal would be mitigated through implementation of mitigation measure MM 4.8.7b that requires onsite replacement of the black cottonwood trees proposed for removal. Economic impacts are not considered physical effects on the environment that subject to consideration under CEQA and thus are not considered in the Draft EIR (CEQA Guidelines Section 15131). Response 20-5: The commenter states that the project would result in increased noise and traffic impacts to local residents and that the roadway will be used more often. The Draft EIR evaluates the traffic and physical environmental effects of this connection to Deerfield Drive. The commenter is also referred to Response 20-1 regarding modifications to the project design since release of the Draft EIR. Response 20-6: The commenter states that the project will result in increased traffic- related hazards to residents, pedestrians, and bicyclists on Deerfield Drive. Draft EIR Section 4.2, Traffic and Circulation, does not identify any traffic operational issues associated with the connection to Deerfield Drive. However, it does identify potential safety concerns on Draft EIR pages 4.2-70 and -71 and identifies mitigation measures MM 4.2.10b through d to address this impact. Response 20-7: The commenter states that the use of Deerfield Drive by large trucks and cars will increase as a result of the proposed project, which would destroy the roadway and increase danger for the residents along this roadway. As shown under the newly proposed Option A, the Deerfield Drive connection is proposed to be reconfigured into a more circuitous route, with the intention of discouraging through traffic between Deerfield Drive east of the project site and the proposed project. Utilizing I-80 between the SR 89 and Donner Pass Road interchanges provides a more direct and feasible route for commercial truck traffic traveling between the Crossroads Commercial Center and the proposed project’s commercial area. In addition, the re-designation of Deerfield Drive to a “minor Town of Truckee Coldstream Specific Plan March 2014 Final Environmental Impact Report 3.0-131 3.0 EVALUATION OF PROJECT MODIFICATIONS AND EIR COMMENTS AND RESPONSES collector” will still result in this roadway having travel restrictions to commercial vehicles on Deerfield Drive due to applicable weight limits of a maximum of 8 tons for this roadway designation and signage directing drivers of commercial vehicles away from Deerfield Drive due to the residential nature of this roadway. The commenter is also referred to Response 20-6 regarding traffic safety. Response 20-8: The commenter states that adding sidewalks to Deerfield Drive would encroach onto landowners’ properties, resulting in decreased property values, removing established trees, and negatively impacting the community character of this established neighborhood. The commenter is referred to Response 20-4. Response 20-9: The commenter states that the increased number of vehicles using Deerfield Drive will result in increased air and noise pollution in this residential area and that accessing the project from the commercial area to the west of the project would result in the same disadvantages to future project residents. The commenter is referred to Response 20-3 regarding noise. In addition, Section 4.4, Air Quality, of the Draft EIR provides an air quality analysis for the proposed project and includes a series of mitigation measures that would ensure that air quality impacts from construction and operational sources are less than significant under the proposed project. Response 20-10: The commenter states that using the commercial area to the west of the project as an access road and not turning Deerfield Drive into a through roadway would be advantageous because these streets are designed to handle high-volume traffic and the commercial area is more appropriate for such use. This comment is noted. The commenter is referred to Response 20-1 regarding modifications in the project design since release of the Draft EIR. Response 20-11: The commenter states that making Deerfield Drive an emergency-only access would eliminate the negative impacts described above. This comment is noted. The commenter is referred to Responses 20-1, 20-6, 20-7, 20-8, and 20-9 above. Response 20-12: The commenter states that making Deerfield Drive an emergency-only access would limit intrusion on Deerfield Drive to pedestrian and bicycle traffic, not increased vehicle traffic. This comment is noted. Response 20-13: The commenter states that making Deerfield Drive an emergency-only access makes the design of the road system in the proposed project and to the west better (numerous curves and “T” intersections), as traffic speeds are kept slower and safer than if vehicles were allowed to travel Coldstream Specific Plan Town of Truckee Final Environmental Impact Report March 2014 3.0-132 3.0 EVALUATION OF PROJECT MODIFICATIONS AND EIR COMMENTS AND RESPONSES east out of the project onto Deerfield Drive, which is a straighter road resulting in increased speeds and increased hazards to pedestrians and bicyclists. The commenter is referred to Response 20-1 regarding modifications to the project design since release of the Draft EIR. Response 20-14: The commenter states that using the commercial area to the west of the project as an access to the project area would eliminate traffic congestion along Deerfield Drive, permit easy access to I-80 at the Donner Pass/Cold Stream Road interchange, direct traffic through the project’s business district rather than the residential area, and provide easy access to businesses on Donner Pass Road and downtown Truckee. This comment is noted. The commenter is referred to Response 20-1 regarding modifications to the project design since release of the Draft EIR. Response 20-15: The commenter asks that Alternatives 2, 3, or 4 be considered since they would not disrupt the safety and serenity of the residential areas along Deerfield Drive.

This comment is noted. The commenter is referred to Section 3.2, Modifications to Project Characteristics, of this document that identifies modification of the project design since release of the Draft EIR. The now proposed Options A and B consist of reduced development potential as compared to the originally proposed Coldstream Specific Plan (see Figures 3.0-1 and 3.0-2). Both options reduce the extent of development on the site. Option A would retain the open roadway connection to Deerfield Drive, but would modify the site design to provide a circuitous roadway system to discourage vehicle trips that pass through the site to access Deerfield Drive and State Route 89 south of Interstate 80. The reduced development intensity and site design would reduce the average daily traffic one-way trips on Deerfield Drive east of the project site to 950 trips (as compared to the originally proposed Coldstream Specific Plan that would generate 2,340 trips). Option B would consist of an emergency-only access to Deerfield Drive and the development of a neighborhood park at this location. Response 22-2: The commenter supports Option 4 as it provides easy access to I-80 and the best bike path alignment to Donner Lake. The commenter further states that the closed Deerfield connection is more bicycle-friendly, and the two river crossings improve the development’s circulation and emergency vehicle options traveling down Deerfield Drive. This comment is noted. The commenter is referred to Response 22-1 regarding modifications to the project design since release of the Draft EIR. Response 22-3: The commenter refers to the economic study, timing of commercial development, and the need for jobs that pay well enough to afford local living expenses. The commenter further states that by reducing the commercial component there would be room for more residential use. This comment is noted. Economic impacts are not considered physical effects on the environment that subject to consideration under CEQA and thus are not considered in the Draft EIR (CEQA Guidelines Section 15131). Response 22-4: The commenter states that there is no economic analysis of the need for residential lots and inquires about the effect of eliminating the interest tax credit for second homes on the local economy. The commenter further states that the commercial services at the proposed project could meet some of the needs of Donner Lake, Armstrong, and Tahoe Donner residents, as this location seems better than other commercial developments proposed downtown.

The commenter is referred to Section 3.2, Modifications to Project Characteristics, of this document that identifies modification of the project design since release of the Draft EIR. The now proposed Options A and B consist of reduced development potential as compared to the originally proposed Coldstream Specific Plan (see Figures 3.0-1 and 3.0-2). Both options reduce the extent of development on the site. Option A would retain the open roadway connection to Deerfield Drive, but would modify the site design to provide a circuitous roadway system to discourage vehicle trips that pass through the site to access Deerfield Drive and State Route 89 south of Interstate 80. The reduced development intensity and site design would reduce the average daily traffic one-way trips on Deerfield Drive east of the project site to 950 trips (as compared to the originally proposed Coldstream Specific Plan that would generate 2,340 trips). Option B would consist of an emergency-only access to Deerfield Drive and the development of a neighborhood park at this location. The Draft EIR identified a significant and unavoidable impact regarding General Plan Circulation Element consistency, but it was only found to be significant and unavoidable for Options 2, 3, and 4 (see also the General Plan consistency analysis provided in Appendix B of the Draft EIR). The newly proposed Option B would also result in a significant and unavoidable impact regarding General Plan Circulation Element consistency, as this option does not provide a through roadway connection to Deerfield Drive east of the project site. The physical effects of connecting Deerfield Drive with the project site as a through roadway have been analyzed in the various technical sections of the Draft EIR and the revised Traffic Impact Analysis prepared for Options A and B, and no new significant environmental effects were identified. Response 23-2: The commenter states that the Town of Truckee General Plan CIR 3, and CIR P2.2 and P2.4, call for minimizing impacts of new development on existing roadways and that lower roadway classifications should not be redesignated to higher roadway classifications. The commenter further states that amending the General Plan to change roadway classifications is backwards planning and is not a minimal impact. This comment is noted. The commenter is referred to Response 23-1. Response 23-3: The commenter sites General Plan Circulation Element Guiding Principles related to minimization of negative impacts on community character, local neighborhoods, and the environment. The commenter states that introducing a high-volume road to the front of the Deerfield Drive properties destroys neighborhood character and reduces property values and quality of life. Coldstream Specific Plan Town of Truckee Final Environmental Impact Report March 2014 3.0-142 3.0 EVALUATION OF PROJECT MODIFICATIONS AND EIR COMMENTS AND RESPONSES The commenter is referred to Response 23-1. Under the newly proposed Option A, and as stated on pages 4.2-54 and -55 of the Draft EIR, the proposed project includes the re-designation of Deerfield Drive to a Minor Collector, rather than a Local Road. If the Town were to implement such an action, the threshold under the General Plan would be different. As shown in Draft EIR Table 4.2-8, a development can be allowed if collectors operating at existing acceptable levels of service will not degrade LOS to unacceptable levels. As indicated in Table 4.2-15 of the Draft EIR, the addition of the proposed project to existing traffic would not result in exceedance of the LOS threshold for Deerfield Drive. As such, the proposed project would be allowable under this newly proposed option. Response 23-4: The commenter states that for Option 1, the Draft EIR describes hazards for pedestrians as potentially significant due to increased traffic. The comment also indicates that there are existing provisions within the Town’s Vision Statement and General Plan calling for safe trails and bikeways that promote opportunities to reduce automobile travel demand. The commenter further states that Option 1 does not provide safety nor does it encourage pedestrian and bike use. Draft EIR Section 4.2, Traffic and Circulation, does not identify any traffic operational issues associated with the connection to Deerfield Drive. However, it does identify potential safety concerns on Draft EIR pages 4.2-70 and -71 and identifies mitigation measures MM 4.2.10b through d to address this impact. As shown in Figures 3.0-1 and 3.0-2, Options A and B of the new project design provides an extensive trail system. Response 23-5: The commenter states that there is a conflict between the Town of Truckee General Plan noise goals related to minimizing exposure to excessive noise and traffic noise associated with Option 1. Noise impacts associated with the proposed Deerfield connection are addressed on Draft EIR pages 4.3-25 and -26 and include the implementation of mitigation measure MM 4.3.5 to reduce the increase in traffic noise with the use of rubberized or open-gap asphalt. Response 23-6: The commenter references the proposed alternative circulation options for the project and the Draft EIR’s evaluation of GP CIR 4. The comment also states that the Draft EIR is not consistent with regard to pointing out when other GP goals are in fact met with the alternative options or Option 1 inconsistencies with the General Plan. As shown in Figures 3.0-1 and 3.0-2, Options A and B of the new project design includes an extensive trail system that interconnects project features and adjoining areas. Draft EIR Appendix B provides a General Plan consistency analysis for the project. The commenter is also referred to Response 23-1 regarding General Plan consistency concerns. Response 23-7: The commenter cites page 70 of the Traffic Impact Analysis in Appendix C of the Draft EIR, which states that the traffic volumes on Deerfield Drive would constitute an arterial road designation. The commenter Town of Truckee Coldstream Specific Plan March 2014 Final Environmental Impact Report 3.0-143 3.0 EVALUATION OF PROJECT MODIFICATIONS AND EIR COMMENTS AND RESPONSES recommends that this information be included in Section 4.2, Transportation and Circulation, of the Draft EIR. The commenter is referred to Response 23-1 regarding modifications in the project design since release of the Draft EIR. As stated in the revised Traffic Impact Analysis (see Appendix B), the newly proposed Option A is estimated to result in 950 average daily trips on the segment of Deerfield Drive east of the project site at full buildout of Option A. Therefore, according to Town engineering standards, this segment of Deerfield Drive would fall under the definition of a collector. Therefore, the roadway is proposed to be designed as a minor collector. A design consistent with the Town’s collector standard is appropriate, as it would accommodate the forecast traffic volumes while moderating traffic speeds and minimizing right-of-way impacts. In addition, the newly proposed Option A, as described previously in this section, would further reduce average daily trips from the project area traveling on Deerfield Drive compared to Option 1 in the Draft EIR due to the reduction in proposed residential units and commercial square footage. Response 23-8: The commenter cites page 70 of the Traffic Impact Analysis in Appendix C of the Draft EIR regarding the suggestion to remove any traffic calming measures to convenience drivers and save trip times. The comment states that this information should be included in Section 4.2, Transportation and Circulation, of the Draft EIR. The information on Page 70 of the Draft EIR Traffic Impact Analysis identified by the commenter regarding traffic calming measures is in relation to the consideration of measures to reduce traffic volumes. The commenter is referred to Response 23-7 regarding modifications to the project design since release of the Draft EIR and the re-analysis of traffic impacts for Options A and B. Response 23-9: The commenter asks that the 2025 General Plan be carefully considered for direction regarding the future connection of Deerfield Drive. This comment is noted. Interpretation of the policy provisions regarding connection to Deerfield Drive for purposes of the Draft EIR traffic impact analysis is provided on Draft EIR pages 4.2-66 and -77 as well as Draft EIR Appendix B. Response 23-10: The commenter states that the proposed project’s Traffic Impact Analysis does not clearly point in the direction of an open road on Deerfield Drive. The comment also cites information from the Traffic Analysis Executive Summary and the Draft EIR regarding roadway levels of service being acceptable on all study roadway segments under current and future conditions with or without the proposed project, including Alternative 2. The commenter is correct that the Draft EIR Traffic Impact Analysis Report and the Draft EIR analysis itself does not advocate for an open connection to Deerfield Drive. The purpose of the Draft EIR is to disclose the physical environmental effects of the proposed Coldstream Specific Plan, including the four roadway design options proposed. Coldstream Specific Plan Town of Truckee Final Environmental Impact Report March 2014 3.0-144 3.0 EVALUATION OF PROJECT MODIFICATIONS AND EIR COMMENTS AND RESPONSES Response 23-11: The commenter states that there are many examples of emergency-only gates in the Town of Truckee and that Option 1 does not match the direction from the General Plan regarding Deerfield Drive. The commenter further states the Town should consider Alternatives 2, 3, or 4. This comment is noted.

As shown in Figures 3.0-1 and 3.0-2 (new project design options A and B), the trail is substantially set back from existing residential parcels along Deerfield Drive. No safety issues are expected from trail use that would require mitigation. Town of Truckee Coldstream Specific Plan March 2014 Final Environmental Impact Report 3.0-147 3.0 EVALUATION OF PROJECT MODIFICATIONS AND EIR COMMENTS AND RESPONSES Coldstream Specific Plan Town of Truckee Final Environmental Impact Report March 2014 3.0-148 3.0 EVALUATION OF PROJECT MODIFICATIONS AND EIR COMMENTS AND RESPONSES Letter 25 Sharon Raney Response 25-1: The commenter states that opening Deerfield Drive to a through roadway would do irreparable harm to the neighborhood and that the road is too narrow to support added traffic. The commenter is referred to Section 3.2, Modifications to Project Characteristics, of this document that identifies modification of the project design since release of the Draft EIR. The now proposed Options A and B consist of reduced development potential as compared to the originally proposed Coldstream Specific Plan (see Figures 3.0-1 and 3.0-2). Both options reduce the extent of development on the site. Option A would retain the open roadway connection to Deerfield Drive, but would modify the site design to provide a circuitous roadway system to discourage vehicle trips that pass through the site to access Deerfield Drive and State Route 89 south of Interstate 80. The reduced development intensity and site design would reduce the average daily traffic one-way trips on Deerfield Drive east of the project site to 950 trips (as compared to the originally proposed Coldstream Specific Plan that would generate 2,340 trips). Option B would consist of an emergency-only access to Deerfield Drive and the development of a neighborhood park at this location. Draft EIR Section 4.2, Traffic and Circulation, does not identify any traffic operational issues associated with the connection to Deerfield Drive. However, it does identify potential safety concerns on Draft EIR pages 4.2-70 and -71 and identifies mitigation measures MM 4.2.10b through d to address this impact. Response 25-2: The commenter expresses concerns with safety, additional traffic, and added noise on Deerfield Drive if it were to become a through roadway, and further states their opposition to Option 1 in favor of making the road emergency-only access. Noise impacts associated with the proposed Deerfield connection are addressed on Draft EIR pages 4.3-25 and -26 and include the implementation of mitigation measure MM 4.3.5 to reduce the increase in traffic noise with the use of rubberized or open-gap asphalt. The commenter is referred to Response 25-1 regarding modifications to the project design since release of the Draft EIR and anticipated reduced traffic volumes.

The commenter further cites Table 4.3-2 of the Draft EIR indicating a measurement date by Bollard in August 2002 and states that 70 dB 550 feet from the center of I-80 is considered “normally unacceptable” by the Truckee Noise Element policies. The Environmental Noise Assessment prepared for the project site by Bollard Acoustical Associates and dated September 12, 2007, used noise measurement surveys conducted in August 2002 as noted in Table 4.3-2 of the Draft EIR. The Draft EIR is incorrect in stating that the noise measurements were conducted at approximately 550 feet from the centerline of I-80. Upon scaling the distance from the noise measurement location C referred to in the Bollard study, the correct distance is approximately 185 feet from the centerline of Interstate 80. The indicated text in the Draft EIR has been revised. The reader is referred to Section 4.0, Minor Revisions to the EIR. In addition, mitigation measure MM 4.3.3 on page 4.3-23 of the Draft EIR has been included to address noise impacts on the project associated with traffic on I-80. Implementation of mitigation measure MM 4.3.3 would reduce noise impacts from I-80 to proposed residences on the project site to a less than significant level. Response 26-2: The commenter cites Table 4.3-2 of the Draft EIR and expresses concerns with the conclusion of noise measurements in the 2007 Bollard study compared to the FHWA modeling program used by JC Brennan & Associates in 2010 to model noise levels 550 feet from the center line of I-80 wherein the results were 6 dB lower than conclusions in the 2007 Bollard study. The commenter is referred to Response 26-1. The JC Brennan & Associates analysis was based on 550 feet. Response 26-3: The commenter cites page 4.3-25 of the Draft EIR related to noise impacts at existing Deerfield residences and disagrees with the conclusion that only “some” of the residences are in excess of the Town of Truckee’s generally accepted exterior noise level standard of 60 dBA CNEL primarily due to I-80 traffic noise. The commenter further states that on page 4.3-25 of the Draft EIR, text states that residents along Deerfield Drive are exposed to traffic noise levels of approximately 61 to 62 dBA CNEL due to I-80 traffic, and all but one of the homes on Deerfield Drive are closer than 550 feet to I-80. The commenter is referred to Response 26-1 above. It is correct that all residents (not “some”) along Deerfield Drive are exposed to existing traffic noise levels which exceed the “normally acceptable” exterior noise level standard of 60 dB CNEL. As previously stated, the Draft EIR inaccurately stated that the measured noise level was 70 dB CNEL at a distance of 550 feet; the distance should be have cited as 185 feet. The indicated text in Town of Truckee Coldstream Specific Plan March 2014 Final Environmental Impact Report 3.0-157 3.0 EVALUATION OF PROJECT MODIFICATIONS AND EIR COMMENTS AND RESPONSES the Draft EIR has been revised. The reader is referred to Section 4.0, Minor Revisions to the EIR. Response 26-4: The commenter references Option 1 and noise levels not exceeding the Town of Truckee’s noise standards under this proposed through roadway option, and provides an opinion that most residents on Deerfield Drive already exceed Town standards from I-80 noise. The commenter further states that the rubberized asphalt proposed for Deerfield Drive in mitigation measure MM 4.3.5 of the Draft EIR is unproven. When adding traffic noise levels from Deerfield Drive and I-80, the increase in traffic noise from the proposed project is less than significant with mitigation outlined in the Draft EIR. The use of rubberized or open-gap asphalt has been successfully used in the United States to reduce traffic noise. The comment provides no countering evidence that mitigation measure MM 4.3.5 would not reduce this impact to less than significant. Response 26-5: The commenter states that opportunities to interact with neighbors would be lost if traffic levels were to be increased by 2,340 trips per day under Option 1, thus adding more noise and danger to the street. The commenter is referred to Section 3.2, Modifications to Project Characteristics, of this document that identifies modification of the project design since release of the Draft EIR. The now proposed Options A and B consist of reduced development potential as compared to the originally proposed Coldstream Specific Plan (see Figures 3.0-1 and 3.0-2). Both options reduce the extent of development on the site. Option A would retain the open roadway connection to Deerfield Drive, but would modify the site design to provide a circuitous roadway system to discourage vehicle trips that pass through the site to access Deerfield Drive and State Route 89 south of Interstate 80. The reduced development intensity and site design would reduce the average daily traffic one-way trips on Deerfield Drive east of the project site to 950 trips (as compared to the originally proposed Coldstream Specific Plan that would generate 2,340 trips). Option B would consist of an emergency-only access to Deerfield Drive and the development of a neighborhood park at this location. Draft EIR Section 4.2, Traffic and Circulation, does not identify any traffic operational issues associated with the connection to Deerfield Drive. However, it does identify potential safety concerns on Draft EIR pages 4.2- 70 and -71 and identifies mitigation measures MM 4.2.10b through d to address this impact. Noise impacts associated with the proposed Deerfield connection are addressed on Draft EIR pages 4.3-25 and -26 and include the implementation of mitigation measure MM 4.3.5 to reduce the increase in traffic noise with the use of rubberized or open- gap asphalt. Response 26-6: The commenter requests that Option 1 in the Draft EIR not be considered and that one of the other options be supported. Coldstream Specific Plan Town of Truckee Final Environmental Impact Report March 2014 3.0-158 3.0 EVALUATION OF PROJECT MODIFICATIONS AND EIR COMMENTS AND RESPONSES This comment is noted. The Draft EIR provides an equal-level of analysis for all four options. The Final EIR now includes analysis of the project modifications since release of the Draft EIR that consists of Option A and B. Response 26-7: The commenter expresses concern with the Draft EIR’s preference toward Option 1, specifically with regard to the discussion on page 4.2-66 related to conflicts with existing goals and policies of the General Plan. The Draft EIR identified a significant and unavoidable impact regarding General Plan Circulation Element consistency, but it was only found to be significant and unavoidable for Options 2, 3, and 4 (see also the General Plan consistency analysis provided in Appendix B of the Draft EIR). The newly proposed Option B would also result in a significant and unavoidable impact regarding General Plan Circulation Element consistency, as this option does not provide a through roadway connection to Deerfield Drive east of the project site. The physical effects of connecting Deerfield Drive with the project site as a through roadway have been analyzed in the various technical sections of the Draft EIR and the revised Traffic Impact Analysis prepared for Options A and B, and no new significant environmental effects were identified. Response 26-8: The commenter states that the Draft EIR appears to be written such that it evaluates the Circulation Element of the General Plan from the perspective that the General Plan has already been amended to change Deerfield Drive into a minor collector. CEQA requires that an EIR evaluate the physical environmental impacts of a project as proposed. As identified in Section 3.0, Project Description, of the Draft EIR, the originally proposed Coldstream Specific Plan included the consideration of four roadway design options. The commenter is referred to Response 26-5 regarding modifications to the project design since release of the Draft EIR. Response 26-9: The commenter cites language from Town of Truckee General Plan Policy 2.4. This comment is noted. Response 26-10: The commenter states that General Plan Policy 2.4 conflicts with Option 1 proposed in the Draft EIR, that an increase in traffic by 2,340 ADT would negatively impact the local neighborhood character of Deerfield Drive, and restates his belief that the Draft EIR appears to be written such that it evaluates the Circulation Element of the General Plan from the perspective that the General Plan has already been amended to change Deerfield Drive into a minor collector. The commenter is referred to Responses 26-7 and 26-8. Response 26-11: The commenter states that the Draft EIR is misleading in that it refers to the Deerfield Drive reclassification as a minor collector when in reality the roadway will change to arterial status and just the design of the road would be kept at minor collector conditions. Town of Truckee Coldstream Specific Plan March 2014 Final Environmental Impact Report 3.0-159 3.0 EVALUATION OF PROJECT MODIFICATIONS AND EIR COMMENTS AND RESPONSES The Draft EIR does not identify Deerfield Drive as proposed to be converted to an arterial as the commenter suggests. Response 26-12: The commenter indicates that the Draft EIR indicates Option 2 presents the greatest compatibility with the current General Plan and that Option 1 would result in the proposed project controlling the General Plan rather than the General Plan guiding the project. This comment is noted. The commenter is referred to Response 26-5 regarding modifications to the project design since release of the Draft EIR. Response 26-13: The commenter asks why the FHWA 108 model was used for the noise analysis rather than the newer FHWA TNM model. The FHWA RD77-108 traffic noise model is still a widely used traffic noise prediction model, and the algorithms are still valid for predicting generalized traffic noise levels. The TNM model was developed to provide a more accurate prediction of traffic noise levels when complex geometry of roadways and interchanges are available as inputs to the model. The model allows for evaluation of elevated roadways or shielding from an overpass. In addition, the TNM model does not allow for the prediction of CNEL. The model predicts peak hour traffic noise levels consistent with the Caltrans and FHWA criteria. Response 26-14: The commenter states there is no indication that the noise model takes into account road surfaces or the effect deteriorating road surfaces have on noise. It is an accurate statement that there will always be variations in traffic noise due to pavement types, aging pavement, changes in traffic mix, or increases in travel speed. However, the FHWA RD77-108 model is generally very accurate in predicting overall traffic noise levels, when the inputs to the model for the day/night distribution of traffic, travel speed, and traffic volumes are correct. Response 26-15: The commenter requests information regarding the margin of accuracy for the noise model due to noise levels being close to Town of Truckee limits. The FHWA model is generally considered to be accurate within 1 to 2 dBA. However, shielding of traffic, elevated receivers, or elevated roadways can affect the actual predicted noise levels. Response 26-16: The commenter questions whether a 6-foot berm will mitigate sound levels from I-80 to acceptable levels. The commenter is referred to Responses 26-1. Response 26-17: The commenter questions placing residential uses in close proximity to I-80 when mitigation for impacts associated with roadway noise is needed. Coldstream Specific Plan Town of Truckee Final Environmental Impact Report March 2014 3.0-160 3.0 EVALUATION OF PROJECT MODIFICATIONS AND EIR COMMENTS AND RESPONSES The commenter is referred to Response 26-1 and Response 26-5 regarding modifications to the project design since release of the Draft EIR. Response 26-18: The commenter references the Draft EIR language that calls for a 1 dB increase in noise levels on I-80 by 2025 when the Town of Truckee General Plan calls for a 2 dB increase, and further states both numbers seem low as Caltrans has contingency plans to increase I-80 to six lanes if needed. The increase in traffic noise levels discussed in the Draft EIR is simply a function of the overall increase in traffic volumes. If Caltrans considers changing the lane geometry on I-80 in the future, they will conduct a noise analysis and determine whether mitigation is required. Response 26-19: The commenter states there is no indication that the Town of Truckee will mitigate noise levels from I-80 for existing Deerfield Drive residences that may be over the threshold as suggested in the General Plan. This comment is noted. Existing noise levels from Interstate 80 are part of the existing environmental conditions that the Draft EIR considers as part of its analysis of project impacts. CEQA does not require the project or the Town to mitigate for existing noise impacts that are not associated with the project. Response 26-20: The commenter states that the traffic analysis shows an increase of 11 non-local trips per hour under Option 1 in the Draft EIR and that this number seems low. The Draft EIR traffic analysis is based on computer traffic modeling and research on traffic generation rates and likely distribution of traffic volumes based on travel times and destinations (see Draft EIR Appendix C and Appendix B of this document). The comment provides no technical analysis to counter the conclusions of the Draft EIR. Response 26-21: The commenter indicates a total ADT for Deerfield Drive under Option 1 in the Draft EIR is not given and calculates 3,420 ADT using the noise analysis numbers (1,080 ADT) added to the traffic analysis increase (2,340 ADT). The commenter is referred to Response 26-5 regarding modifications to the project design and re-evaluation of project traffic volumes on Deerfield Drive (see also Appendix B of this document). A revised Traffic Impact Analysis was prepared for the newly proposed Option A. In this analysis, the total increase in peak-hour trips on Deerfield Drive from the proposed project is estimate at 79 trips, plus an additional 17 “cut though” trips to Donner Lake for a total of 96 peak hour trips. ADT calculated under Option A along this segment of Deerfield Drive was estimated by applying a factor of 10.15 to the peak hour volume increase generated from the proposed project and 8.61 to the peak hour volume increase generated from the “cut through” trips, which is consistent with the ADT factor applied in the Truckee General Plan Traffic Study for other roadways in the area. When multiplying the peak hour trips by the factors listed above (10.15 x 79 and 8.61 x 17), Option A yields an increase of about 950 ADT to Deerfield Drive. In addition, this segment of Deerfield Drive has an existing Town of Truckee Coldstream Specific Plan March 2014 Final Environmental Impact Report 3.0-161 3.0 EVALUATION OF PROJECT MODIFICATIONS AND EIR COMMENTS AND RESPONSES ADT of about 350 trips on a typical summer day. When added together (950 + 350), the ADT on this segment of Deerfield Drive under Option A would be approximately 1,300 average daily trips. Response 26-22: The commenter references the proposed 20-foot landscape buffer between the Village Green Residential zoning district and the Caltrans property, and indicates that while this may provide a visual screen, it will not block dust from prevailing winds and noise coming from the Caltrans property. Operations from the Caltrans property south of the project site are part of the existing environmental conditions and are associated with the impacts of the proposed project. However, Caltrans operations are temporary (as part of current roadway improvements to Interstate 80). The Draft EIR did not identify any significant noise issues associated with the Caltrans property based on noise studies of the project site. Response 26-23: The commenter states that property values on Deerfield Drive would decrease under Option 1. This comment is noted. Economic impacts are not considered physical effects on the environment that subject to consideration under CEQA and thus are not considered in the Draft EIR (CEQA Guidelines Section 15131). Response 26-24: The commenter references travel times estimated in the Draft EIR and suggests the use of I-80 should be encouraged rather than the use of local roadways to reduce travel times and reduce the occurrence of accidents. The commenter states that use of local roadways involves more safety concerns such as cars backing out of driveways. This comment is noted. Draft EIR Section 4.2, Traffic and Circulation, does not identify any traffic operational issues or safety issues with vehicles backing out from driveways associated with the connection to Deerfield Drive. However, it does identify potential safety concerns on Draft EIR pages 4.2-70 and -71 and identifies mitigation measures MM 4.2.10b through d to address this impact. Response 26-25: The commenter takes exception to the argument that the additional trips resulting from a through roadway on Deerfield Drive under Option 1 in the Draft EIR are justified because it allows for a local roadway connection in the community. The commenter further references pages 53–54 of the Traffic Impact Analysis in Appendix C of the Draft EIR and states that the reduction in use of Donner Pass Road in 2030 under Option 1 is negligible compared to Options 2, 3, and 4 which do not allow through traffic on Deerfield Drive. This comment is noted. Response 26-26: The commenter states that allowing Deerfield Drive to be a through roadway accommodating local road access between the project area and SR 89 does not promote community togetherness, as it places an undue burden on Deerfield Drive residents. Coldstream Specific Plan Town of Truckee Final Environmental Impact Report March 2014 3.0-162 3.0 EVALUATION OF PROJECT MODIFICATIONS AND EIR COMMENTS AND RESPONSES This comment is noted. The Draft EIR does evaluate the physical environmental effects of the connection to Deerfield Drive as an option of the project and this Final EIR evaluates this environmental effect for Option A associated with the modifications to the project design since release of the Draft EIR. Response 26-27: The commenter states that Option 1 will do nothing to enhance the Deerfield Drive neighborhood and will lower the quality of life for these residences. This comment is noted. Town of Truckee Coldstream Specific Plan March 2014 Final Environmental Impact Report 3.0-163 3.0 EVALUATION OF PROJECT MODIFICATIONS AND EIR COMMENTS AND RESPONSES Coldstream Specific Plan Town of Truckee Final Environmental Impact Report March 2014 3.0-164 3.0 EVALUATION OF PROJECT MODIFICATIONS AND EIR COMMENTS AND RESPONSES Letter 27 Charles & Lisa Smith; Ralph & Brenda Coronado Response 27-1: The commenter does not support amending the Town of Truckee General Plan by changing Deerfield Drive from a local road to a minor collector to accommodate a larger volume of traffic associated with Option 1. The commenter also states that Option 1 conflicts with General Plan policies and further impacts the neighborhood which is already impacted by noise. The comment supports one of the other options in the DEIR. The commenter is referred to Section 3.2, Modifications to Project Characteristics, of this document that identifies modification of the project design since release of the Draft EIR. The now proposed Options A and B consist of reduced development potential as compared to the originally proposed Coldstream Specific Plan (see Figures 3.0-1 and 3.0-2). Both options reduce the extent of development on the site. Option A would retain the open roadway connection to Deerfield Drive, but would modify the site design to provide a circuitous roadway system to discourage vehicle trips that pass through the site to access Deerfield Drive and State Route 89 south of Interstate 80. The reduced development intensity and site design would reduce the average daily traffic one-way trips on Deerfield Drive east of the project site to 950 trips (as compared to the originally proposed Coldstream Specific Plan that would generate 2,340 trips). Option B would consist of an emergency-only access to Deerfield Drive and the development of a neighborhood park at this location. Noise impacts associated with the proposed Deerfield connection are addressed on Draft EIR pages 4.3-25 and -26 and include the implementation of mitigation measure MM 4.3.5 to reduce the increase in traffic noise with the use of rubberized or open-gap asphalt.

The commenter is referred to Section 3.2, Modifications to Project Characteristics, of this document that identifies modification of the project design since release of the Draft EIR. The now proposed Options A and B consist of reduced development potential as compared to the originally proposed Coldstream Specific Plan (see Figures 3.0-1 and 3.0-2). Both options reduce the extent of development on the site. Option A would retain the open roadway connection to Deerfield Drive, but would modify the site design to provide a circuitous roadway system to discourage vehicle trips that pass through the site to access Deerfield Drive and State Route 89 south of Interstate 80.

Draft EIR Section 4.2, Traffic and Circulation, does not identify any traffic operational issues associated with the connection to Deerfield Drive that would require widening of the roadway. However, it does identify potential safety concerns on Draft EIR pages 4.2-70 and -71 and identifies mitigation measures MM 4.2.10b through d to address this impact. Response 28-2: The commenter states that opening Deerfield Drive as a through roadway is not a viable solution for access to the project area and requests that this option be eliminated. This comment is noted.

The commenter further states that Figure 3.0-7 on page 3.0-21 of the Draft EIR references the creek enhancement project as “potential,” and it should be a planned element of the project The commenter is referred to Section 3.2, 3.3 and Appendix A of this document that addresses the proposed restoration of Cold Creek. Section 3.3 identifies that the additional details on the proposed restoration do not result in any new significant environmental impacts or a substantial increase environmental impacts that were identified in the Draft EIR. Response 29-2: The commenter states that the Cold Creek Enhancement element of the proposed project will provide significant water quality, habitat, aesthetic, and flood protection benefits. The commenter further states that the proposed Cold Creek Enhancement, in combination with a similar enhancement project conducted upstream by the California Department of Parks and Recreation, will assist in significantly reducing sediment loading into the Truckee River, which is listed as impaired for excess fine sediment. This comment is noted. The commenter is referred to Response 29-1.

The commenter asks that the alignment and ingress/egress studies be completed and that the Truckee Trails Foundation be included in trail alignment discussions. Potential trail alignments and associated connections into Donner Memorial State Park have been identified (see Figures 3.0-1 and 3.0-2). However, the commenter is correct that the final trail alignment has not been determined. Mitigation measure MM 4.11.3.2 on page 4.11-15 of the Draft EIR requires that prior to finalization of exact trail alignments through the project site and connection points to Donner Memorial State Park, the project applicant shall coordinate with California Department of Parks and Recreation staff and Town of Truckee staff to ensure compatibility of trail alignment and compatibility of uses on the connected trails.

Yang, Taylor & Wiley Response 31-1: The commenter states that regarding the proposed enhancements to the onsite ponds, Cold Creek and Donner Creek, the Draft EIR analysis was prepared at a programmatic level due to insufficient details; however, the proposed restoration and management plan for the ponds and 25 percent construction drawings for the restoration plan for Cold Creek were previously provided for consideration and should have been analyzed on a project level. The commenter requests that the EIR be revised to analyze the proposed restoration plan on a project level. The commenter is referred to Sections 3.2 and 3.3 and Appendix A of this document that addresses the proposed restoration of Cold Creek. Section 3.3 identifies that the additional details on the proposed restoration do not result in any new significant environmental impacts or a substantial increase environmental impacts that were identified in the Draft EIR. Response 31-2: The commenter acknowledges that the Draft EIR assumed the proposed project could result in a total of 486 dwelling units, consisting of 345 primary dwellings and 141 secondary dwellings. The commenter suggests the assumption of 141 second dwelling units likely results in a gross overestimation of this aspect of the project and requests that the Draft EIR’s analysis be updated based on the assumption that a maximum of 75 second dwelling units would be constructed. The commenter is referred to Section 3.2, Modifications to Project Characteristics, of this document that identifies modification of the project design since release of the Draft EIR. The now proposed Options A and B consist of reduced development potential as compared to the originally proposed Coldstream Specific Plan (see Figures 3.0-1 and 3.0-2). Both options reduce the extent of development on the site. Option A would retain the open roadway connection to Deerfield Drive, but would modify the site design to provide a circuitous roadway system to discourage vehicle trips that pass through the site to access Deerfield Drive and State Route 89 south of Interstate 80. Option B would consist of an emergency- only access to Deerfield Drive and the development of a neighborhood park at this location. Section 3.3 and Appendix B of this document provides an updated traffic impact analysis for Options A and B. This analysis has determined that extent of traffic impacts would be reduced and no new significant environmental impacts or an increased severity of identified environmental impacts would occur beyond what was evaluated in the Draft EIR. The Draft EIR was prepared based upon a reasonable assumption of allowable development under the Town of Truckee Development Code. The newly proposed Options A and B considers both a maximum of 300 residential dwelling units and up to 75 secondary dwelling units which could be constructed as part of the project. Response 31-3: The commenter refers to an attachment to their letter containing comments submitted by Fehr & Peers regarding Institute of Traffic Engineers (ITE) trip generation rates, and requests that the Draft EIR’s Town of Truckee Coldstream Specific Plan March 2014 Final Environmental Impact Report 3.0-193 3.0 EVALUATION OF PROJECT MODIFICATIONS AND EIR COMMENTS AND RESPONSES assessment of impacts and mitigation be based on a maximum of 75 second dwelling units and locally valid trip generation rates used in the Town of Truckee General Plan EIR and documented in the TransCAD Model Calibration Memorandum prepared by LSC Consultants dated April 20, 2006. Appendix B contains an updated traffic impact analysis prepared by LSC in response to changes to the project since release of the Draft EIR as well as consideration of traffic analysis assumptions. Response 31-4: The commenter requests that the EIR be augmented to include an alternative to the proposed project that would allow for a maximum of 300 dwelling units, including a maximum of an additional 75 secondary dwelling units, and 30,000 square feet of commercial uses. The commenter further requests that this alternative be analyzed using the locally valid trip generation rates used in the Town of Truckee General Plan EIR and ITE trip generation rates. The commenter is referred to Responses 33-2. Response 31-5: The commenter refers to the first paragraph on page 1.0-1 in Section 1.0, Introduction, Subsection 1.2 of the Draft EIR and requests that the EIR be revised to provide a project-level analysis of the proposed pond and creek restoration. The commenter is referred to Response 31-1. Response 31-6: The commenter references the ministerial approvals included in the Draft EIR on page 1.0-2 in Subsection 1.3 and states that the project is proposed to be constructed in phases; therefore, the permits listed should be plural instead of singular. The indicated text in the Draft EIR has been revised. The reader is referred to Section 4.0, Minor Revisions to the EIR. Response 31-7: The commenter references the Hydrology and Water Quality heading for Table 1.0-1 on page 1.0-9 and suggests Section 4.8 be referenced in the “Response” column for comments that pertain to wetlands and waters of the U.S. because some of the comments in this section pertain to biological resources.

The indicated text in the Draft EIR has been revised. The reader is referred to Section 4.0, Minor Revisions to the EIR. Response 31-22: The commenter references the third paragraph on page 3.0-19 of the Draft EIR and indicates the statement “While secondary units are allowed per code, none are proposed as part of the project” conflicts with the Draft EIR’s assumption that up to 141 secondary dwelling units could be constructed as part of the project. The commenter is referred to Response 33-2. The Draft EIR was prepared based upon a reasonable assumption of allowable development under the Town of Truckee Development Code. The newly proposed Options A and B considers both a maximum of 300 residential dwelling units and up to 75 secondary dwelling units which could be constructed as part of the project. Response 31-23: The commenter references text under the Improved Commercial Interface subheading on page 3.0-20 of the Draft EIR and suggests language be added indicating the project applicant acquired the property that formerly housed Madigan’s Restaurant and demolished the Coldstream Specific Plan Town of Truckee Final Environmental Impact Report March 2014 3.0-196 3.0 EVALUATION OF PROJECT MODIFICATIONS AND EIR COMMENTS AND RESPONSES vacant building in an effort to improve the viability of the proposed commercial uses.

The indicated text in the Draft EIR has been revised. The reader is referred to Section 4.0, Minor Revisions to the EIR. Response 31-25: The commenter references the last paragraph on page 3.0-20 and the first paragraph on page 3.0-27 of the Draft EIR regarding enhancements to the ponds, Cold Creek, and Donner Creek. The commenter requests that the restoration and enhancement plans associated with the onsite ponds, Cold Creek, and Donner Creek be analyzed at a project level. The commenter states that information was previously provided to permit such analysis. The commenter further states that the Draft EIR should include reference to the proposed pedestrian bridge crossing of Cold Creek located north of the vehicular bridge. The commenter is referred to Responses 33-1, F-4 and F-5. In addition, the indicated text in the Draft EIR has been revised. The reader is referred to Section 4.0, Minor Revisions to the EIR. Response 31-26: The commenter references Figure 3.0-7 on page 3.0-27 of the Draft EIR regarding buffer areas for the project and suggests inserting and referencing Figure 3-23 from the Coldstream Specific Plan to better depict proposed buffer areas. Figure 3-23 from the Coldstream Specific Plan is included in Section 4.1, Land Use, of the Draft EIR as Figure 4.1-4 and was used to analyze the project’s proposed buffer areas. Response 31-27: The commenter references pages 3.0-27 to -28 of the Draft EIR regarding Option 1 and the connection to Deerfield Drive, and asks that sidewalk construction on the south side of the roadway only be confirmed. The analysis contained within the Draft EIR evaluated construction of a sidewalk on the south side of Deerfield Drive only and not on the north side of this roadway. Response 31-28: The commenter references Figure 3.0-16 and the discussion in the Draft EIR on page 3.0-40 regarding a Class I Bicycle Trail or Path, indicates these improvements were not proposed by the project applicant, and suggests a note be added that construction of offsite segments of these trail and path improvements will be the responsibility of the Town of Truckee or by a third party. Town of Truckee Coldstream Specific Plan March 2014 Final Environmental Impact Report 3.0-197 3.0 EVALUATION OF PROJECT MODIFICATIONS AND EIR COMMENTS AND RESPONSES While it is acknowledged that the Town of Truckee would be involved with the construction of off-site trail segments within public right-of-way, the trail improvements are a component of the project and would involve the project applicant. Response 31-29: The commenter references page 3.0-40 of the Draft EIR regarding recreational trials and requests the width of proposed recreational trails be listed as 2 to 8 feet, not 4 to 8 feet. The indicated text in the Draft EIR has been revised. The reader is referred to Section 4.0, Minor Revisions to the EIR. Response 31-30: The commenter references page 3.0-49 of the Draft EIR regarding soil import and requests an update to this discussion indicating fill material from the adjacent State Parks property would be imported to the project site as part of the Cold Creek restoration and enhancement work on the State Parks property. The commenter further requests that the second to last sentence of this discussion be revised to note that imported fill material would be placed at various locations throughout the project area, not solely in the Lakeside Residential and Forest Residential areas. The indicated text in the Draft EIR has been revised. The reader is referred to Section 4.0, Minor Revisions to the EIR. The commenter is also referred to Response F-8. Response 31-31: The commenter states that the fifth reference on page 3.0-57 of the Draft EIR should refer to Kenkay Associates, not Kenkay Association. The indicated text in the Draft EIR has been revised. The reader is referred to Section 4.0, Minor Revisions to the EIR. Response 31-32: The commenter references buildout assumptions under the Coldstream Specific Plan on pages 4.0-2 and -3 of the Draft EIR and requests that the EIR be revised to analyze a maximum of 75 secondary dwelling units The commenter is referred to Responses 31-2. Response 31-33: The commenter references the second paragraph under the General Assumptions heading on page 4.0-3 of the Draft EIR and indicates the statement regarding secondary units not being proposed as part of the project conflicts with the Draft EIR’s assumption that up to 141 secondary dwelling units could be constructed. While secondary dwelling units are not specifically proposed in the Coldstream Specific Plan’s Section 1.4 Project Description, as stated in the Draft EIR, secondary units are allowed per the Town of Truckee Development Code and therefore a reasonable assumption was made that up to 141 secondary dwelling units could be developed as part of the proposed project. This information was considered in the technical analyses prepared for the Draft EIR. Since release of the Draft EIR, the project applicant has proposed two revised project alternatives (Options A and B), both of which include up to 75 secondary dwelling units. Coldstream Specific Plan Town of Truckee Final Environmental Impact Report March 2014 3.0-198 3.0 EVALUATION OF PROJECT MODIFICATIONS AND EIR COMMENTS AND RESPONSES Response 31-34: The commenter references the third paragraph under General Assumptions on page 4.0-3 of the Draft EIR and requests that the discussion reflect that soils material from the adjacent State Parks property would also be imported to the project site as part of the Cold Creek restoration and enhancement work occurring on the State Parks property. The commenter further references an exhibit from State Parks depicting the stockpile location for material to be exported. The commenter is referred to Response F-8 and 31-30. The indicated text in the Draft EIR has been revised. The reader is referred to Section 4.0, Minor Revisions to the EIR. Response 31-35: The commenter references the second paragraph under the Surrounding Land Uses heading on page 4.1-2 of the Draft EIR and requests that information regarding the most recent list of proposed State Park closures be reflected. According to a news release from the California Department of Parks and Recreation dated May 13, 2011, Donner Memorial State Park is not listed as a State Park to be closed in order to meet the State’s 2011/12–2012/13 General Fund reductions. No changes to the Draft EIR are required. Response 31-36: The commenter references Figure 4.1-2 on page 4.1-5 of the Draft EIR and indicates that this figure is missing the northern portion of the project site. The indicated text in the Draft EIR has been revised. The reader is referred to Section 4.0, Minor Revisions to the EIR. Response 31-37: The commenter references the third paragraph under the Planned Community 1 subheading on page 4.1-9 of the Draft EIR and indicates that the reference to 50 acres of developable area is incorrect and should be revised to reflect 70 acres as shown in Table 4.1-1 on page 4.1-9. The indicated text in the Draft EIR has been revised. The reader is referred to Section 4.0, Minor Revisions to the EIR. Response 31-38: The commenter references mitigation measure MM 4.1.3 on pages 4.1-21 and -22 of the Draft EIR and states that Donner Memorial State Park is incorrectly referenced twice in this mitigation measure, that the timing of providing a gated access point to the State Parks property should be prior to approval of a final subdivision map for the Lakeside Residential area, and that the provision of an access point will require that State Parks provide indemnification and insurance requirements to the satisfaction of the property owner. The commenter is referred to Section 4.0, Minor Revisions to the EIR, associated with changes to this mitigation measure to address this issue as well as modifications in the project design since release of the Draft EIR. Indemnification and insurance requirements are not a State CEQA Guidelines related issue and are therefore not included in this mitigation measure. Town of Truckee Coldstream Specific Plan March 2014 Final Environmental Impact Report 3.0-199 3.0 EVALUATION OF PROJECT MODIFICATIONS AND EIR COMMENTS AND RESPONSES Response 31-39: The commenter refers to an attachment to their letter containing comments submitted by Fehr & Peers regarding Institute of Traffic Engineers (ITE) trip generation rates, indicates that the Draft EIR likely overestimated the project’s trip generation, and requests that the Draft EIR’s assessment of impacts and mitigation be based on a maximum of 75 second dwelling units and locally valid trip generation rates used in the Town of Truckee General Plan EIR and documented in TransCAD Model Calibration Memorandum prepared by LSC Consultants dated April 20, 2006. The commenter is referred to Response 31-3 and Appendix B. Response 31-40: The commenter references the discussion under Deerfield Drive on page 4.2-5 of the Draft EIR and requests that peak hour two-way volume of 110 and peak hour peak direction volume of 60 be revised to reflect the traffic volumes in Table 4.2-1 on page 4.2-7. The indicated text in the Draft EIR has been revised. The reader is referred to Section 4.0, Minor Revisions to the EIR. Response 31-41: The commenter references the second paragraph on page 4.2-27 of the Draft EIR and requests that the discussion of Options 1 through 4 should also refer to Figures 3.0-11 through 3.0-14 of the Draft EIR. The indicated text in the Draft EIR has been revised. The reader is referred to Section 4.0, Minor Revisions to the EIR. It should be noted that Options 1 through 4 are no longer under consideration as project components. Response 31-42: The commenter references the discussion under the Trip Generation subheading on pages 4.2-27 to -28 of the Draft EIR and refers to an attachment to their letter containing comments submitted by Fehr & Peers regarding trip generation rates and land use assumptions used in the Draft EIR. The commenter expresses concern that using 141 secondary dwelling units occupied by a full-time resident exaggerates the project’s traffic impacts and fair-share responsibility for traffic mitigation. The commenter is referred to Responses 31-2. Response 31-43: The commenter expresses concern with the Draft EIR’s use of full ITE generation rates. The commenter indicates that more valid locally collected trip generation rates are available as contained in the Town of Truckee General Plan EIR and states that use of ITE rates in this circumstance appears to be inconsistent with the best practices recommended by ITE. The commenter is referred to Response 31-3. Response 31-44: The commenter refers to mitigation measure MM 4.2.2a on pages 4.2-57 and -58 of the Draft EIR and refers to comments attached to their letter from Fehr & Peers. The commenter indicates that Table 4.2-13 of the Draft EIR shows the SR 89 South/Donner Pass Road/Frates Lane intersection would operate at LOS E with or without the project, the project would not Coldstream Specific Plan Town of Truckee Final Environmental Impact Report March 2014 3.0-200 3.0 EVALUATION OF PROJECT MODIFICATIONS AND EIR COMMENTS AND RESPONSES contribute more that a 5 percent increase to traffic volume at this intersection per the threshold of significance listed on page 4.2-25, and the project impact to this intersection should be deemed less that significant. The commenter further states that no mitigation should be required at this intersection and that since the Notice of Preparation was issued, the improvements identified in mitigation measure MM 4.2.2a have since been constructed. With or without the newly proposed Options A and B, the SR 89/Donner Pass Road/Frates Lane intersection is forecast to exceed the LOS threshold for 2010 and 2030 summer peak hour conditions. The signal Improvements and roundabout improvement options (see mitigation measure MM 4.2.2a) to mitigate this impact would provide acceptable LOS conditions. The signal improvements were installed subsequent to 2010. However, the proposed project contributes to this level of service impact and therefore is responsible for its fair share cost of short term signal improvements and long term roundabout improvements. The proposed project’s fair share percentage of the costs for these improvements is calculated in the revised traffic impact analysis provided in Appendix B of this document. Response 31-45: The commenter refers to mitigation measure MM 4.2.2b on pages 4.2-58 to -59 of the Draft EIR and refers to comments attached to their letter from Fehr & Peers. The commenter believes that under Option 1 there would be no existing-plus-project impact to the I-80 Westbound Ramps/Donner Pass Road intersection and opines that mitigation measures MM 4.2.2b should be revised to clarify that the proposed roundabout does not apply to Option 1. While the commenter is correct in stating that the LOS threshold in the 2010 summer PM peak hour would not be exceeded under the newly proposed Option A, the referenced mitigation measure would still be required in year 2030. In this instance, the proposed project contributes to total future growth in summer PM hour traffic at this intersection between 2010 and 2030. In addition, according to Table CIR-6 in the Town of Truckee 2025 General Plan Circulation Element, the proposed project would meet the criteria for an allowable development so long as it constructs this improvement. Therefore, the proposed project is being required to construct this improvement and pay the applicable Town of Truckee traffic impact fees. The project would then be reimbursed its fair share portion of the improvements over time from future development pursuant to Town standards. Response 31-46: The commenter refers to mitigation measure MM 4.2.2c on page 4.2-59 of the Draft EIR regarding the requirement for construction of a roundabout at the I-80 Eastbound Ramps/Donner Pass Road/Coldstream Road intersection. The commenter further states that this intersection already operates at LOS F under the 2010 no project conditions and that this deficiency should be clearly noted in the EIR. The commenter recommends impacts at this intersection be evaluated in accordance with the LOS thresholds in the Highway Capacity Manual for signalized intersections and the analysis be included in the EIR. Town of Truckee Coldstream Specific Plan March 2014 Final Environmental Impact Report 3.0-201 3.0 EVALUATION OF PROJECT MODIFICATIONS AND EIR COMMENTS AND RESPONSES The commenter is correct in stating that there is an existing deficiency under the 2010 no project condition at the I-80 Eastbound Ramps/Donner Pass Road/Coldstream Road intersection. As stated under Impact 4.2.2 on page 4.2-56 of the Draft EIR, the I-80 Eastbound Ramps/Coldstream Road/ Donner Pass Road intersection exceeds the Town’s LOS thresholds under 2010 without project conditions. This condition is also shown in Table 4.2-13 on page 4.2-48. Evaluating the impacts at this intersection using the Highway Capacity Manual’s LOS thresholds for signalized intersections is not appropriate, as this intersection is currently stop-controlled, not signalized. Under existing plus project and future plus project conditions with the roundabout, and applying signalized intersection LOS thresholds, the intersection was found to operate at an acceptable level of service. Response 31-47: The commenter refers to mitigation measure MM 4.2.3a on page 4.2-65 of the Draft EIR and requests that more detail be provided regarding the nature and scope of proposed improvements related to the southbound left turn lane and increasing the capacity of the existing Coldstream Road Bridge. Under the newly proposed Option B, the revised traffic impact analysis (see Appendix B of this document) determined that the increase in traffic under this option would result in exceeding the available storage length by 5 feet during peak periods on Cold Stream Road. Based on this analysis at the Cold Stream Road/Deerfield Drive intersection, mitigation measure MM 4.2.3a is still required, but has been modified given the reduced extent of the impact (see Section 4.0 for revisions to this mitigation measure. Response 31-48: The commenter refers to Impact 4.2.5 on page 4.2-66 of the Draft EIR pertaining to the significant and unavoidable impact related to conflicts with existing goals and policies of the Town of Truckee General Plan Circulation Element Policy 2.4 and Goal CIR-4. The commenter disagrees with the Draft EIR’s conclusion that Options 2, 3, and 4 would create a development that is not integrated into the circulation network due to not allowing open roadway access between the project and the adjoining Deerfield Drive neighborhood. The commenter cites other guidance in Circulation Element Policy 2.4 and Goal CIR-4, believes the four roadway options are consistent with the Circulation Element with respect to the connection with Deerfield Drive, and states that the Draft EIR’s conclusion with respect to Impact 4.2.5 should be revised accordingly. This interpretation of General Plan Circulation Element Policy 2.4 and Goal CIR-4 is based on consultation with Town staff and is consistent with the intent of these policies of interconnecting neighborhoods in the Town. Response 31-49: The commenter refers to mitigation measure MM 4.2.10c on page 4.2-71 of the Draft EIR and seeks clarification regarding reference on page 4.3-22 to a potential sidewalk along the south side of Deerfield Drive and whether this is the same sidewalk as that referred to in mitigation measure MM 4.2.10c. Coldstream Specific Plan Town of Truckee Final Environmental Impact Report March 2014 3.0-202 3.0 EVALUATION OF PROJECT MODIFICATIONS AND EIR COMMENTS AND RESPONSES The sidewalk on the south side of Deerfield Drive referenced in the discussion under Impact 4.3.1 on page 4.3-22 of the Draft EIR is in fact the same sidewalk as referenced in mitigation measure MM 4.2.10c, but has removed as a result of project redesign. Section 4.3, Noise, of the Draft EIR has been revised to reflect this clarification. The reader is referred to Section 4.0, Minor Revisions to the EIR. Response 31-50: The commenter refers to Table 4.3-9 on page 4.3-15 of the Draft EIR related to the Option 1 traffic noise levels and states that under the Deerfield Drive “To end of pavement” segment, the change in noise level appears to be +5dBA, not +6dBA as listed in the Change column after Existing and +Option 1 columns. The indicated text in the Draft EIR has been revised. The reader is referred to Section 4.0, Minor Revisions to the EIR.

Response 31-81: The commenter references the third paragraph on page 4.11-14 of the Draft EIR and indicates that since release of the Draft EIR, public outreach and coordination with the TDRPD has occurred, resulting in the likelihood that the project will include some dedication of parkland to meet its Quimby Act obligations. The commenter further requests that the reference to payment of fees for compliance with Quimby Act obligations also include the potential for parkland dedication. The indicated text in the Draft EIR has been revised. The reader is referred to Section 4.0, Minor Revisions to the EIR. Response 31-82: The commenter references the second paragraph under the Methodology subheading on page 4.11-19 of the Draft EIR and states they have the same comment as their previous comment regarding the Methodology subheading on page 4.11-5 in Section 4.11, Community Services, pertaining to the EIR’s assumptions on secondary dwelling units. The commenter is referred to Response 31-33. Response 31-83: The commenter references the first paragraph on page 4.11-20 of the Draft EIR and indicates that there is a typographical error in the fourth sentence, which should state “purpose of funding,” not “purpose or funding.” The indicated text in the Draft EIR has been revised. The reader is referred to Section 4.0, Minor Revisions to the EIR. Response 31-84: The commenter references the second paragraph under the Methodology subheading on page 4.12-7 of Section 4.12, Utilities and Service Systems, in the Draft EIR and indicates that the statement regarding no secondary units being proposed as part of the Coldstream Specific Plan conflicts with the Draft EIR’s assumptions that up to 141 secondary dwelling units could be constructed as part of the project. The commenter is referred to Response 31-33. Coldstream Specific Plan Town of Truckee Final Environmental Impact Report March 2014 3.0-208 3.0 EVALUATION OF PROJECT MODIFICATIONS AND EIR COMMENTS AND RESPONSES Response 31-85: The commenter references the second paragraph on page 4.12-8 of the Draft EIR and indicates there would likely be some limited use of water associated with recreation and open space properties for irrigation, dust suppression, restoration, and maintenance activities, etc. The commenter recommends that an appropriate water demand factor be applied to these properties with pond acreage of the open space zone netted out. Currently there are details within the Specific Plan regarding the type of uses in the recreation and open space areas that a reliable irrigation factor could be applied. Any estimation of such water demand would be speculative. Given the limited amount of recreation land area proposed and proposed retention of much of the open space area in its current condition, the additional water demand is expected to be minor in relation to the overall project water demands identified on Draft EIR page 4.12-8. Response 31-86: The commenter references the seventh paragraph on page 4.12-8 of the Draft EIR and states that the minimum fire flow requirements quoted (1,000 gallons per minute [gpm] for residential uses and 1,500 gpm for commercial uses) are inconsistent with the minimum requirements outlined on page 4.11-3 of the Draft EIR. Pursuant to a letter received from Bob Bena (DCFM) of the Truckee Fire Protection District dated July 8, 2009, regarding the Coldstream Specific Plan, residential areas shall have a minimum fire flow of 1,500 gpm for residential areas and 2,500 gpm for commercial areas. The information on page 4.12-8 of the Draft EIR will be revised to reflect these requirements. The reader is referred to Section 4.0, Minor Revisions to the EIR. Response 31-87: The commenter references the second paragraph under the Methodology subheading on page 4.12-15 of the Draft EIR and states that they have the same comment as their previous comment regarding the Methodology subheading on page 4.12-7 in Section 4.12, Utilities and Service Systems, pertaining to the EIR’s assumptions on secondary dwelling units. The commenter is referred to Response 31-33. Response 31-88: The commenter references the second paragraph under the Methodology subheading on page 4.12-21 of the Draft EIR and states that they have the same comment as their previous comment regarding the Methodology subheading on page 4.12-7 in Section 4.12, Utilities and Service Systems, pertaining to the EIR’s assumptions on secondary dwelling units. The commenter is referred to Response 31-33. Response 31-89: The commenter references the first paragraph under the Methodology subheading on page 4.12-26 of the Draft EIR and states that they have the same comment as their previous comment regarding the Methodology subheading on page 4.12-7 in Section 4.12, Utilities and Town of Truckee Coldstream Specific Plan March 2014 Final Environmental Impact Report 3.0-209 3.0 EVALUATION OF PROJECT MODIFICATIONS AND EIR COMMENTS AND RESPONSES Service Systems, pertaining to the EIR’s assumptions on secondary dwelling units. The commenter is referred to Response 31-33. Response 31-90: The commenter references the discussion under the Ownership Affordability subheading on page 4.13-5 in Section 4.13, Population, Housing, and Socioeconomics, of the Draft EIR and states that the first sentence regarding median housing prices in Truckee being shown on Table 4.13-6 is not correct. Rather, Table 4.13-16 provides affordable rent and purchase price income by category in Nevada County. The commenter’s comment is not clear as there is no Table 4.13-16 in the Draft EIR. As shown in the Draft EIR, Table 4.13-6 provides information on affordable rent and purchase price by income category for Nevada County. As stated in the discussion under the Housing Costs and Rents subheading on page 4.13-4 of the Draft EIR, the median sales price for housing in Truckee was $469,500. This price exceeds the affordability range for all income categories except above moderate-income households as defined in Table 4.13-6. The text in the Draft EIR has been revised to remove the reference to Table 4.13-6 under the Ownership Affordability discussion on page 4.13-5. The reader is referred to Section 4.0, Minor Revisions to the EIR. Response 31-91: The commenter references the second paragraph under Impact 4.13.1 on page 4.13-14 in the Draft EIR and indicates that the statement regarding no secondary units being proposed as part of the Coldstream Specific Plan conflicts with the Draft EIR’s assumptions that up to 141 secondary dwelling units could be constructed as part of the project. The commenter is referred to Response 31-33. Response 31-92: The commenter references the second paragraph under Impact 4.13.2 on page 4.13-15 of the Draft EIR and states that there is currently only one residence on the project site, not a “few” as indicated in the discussion. The commenter acknowledges the existence of another residence in the area, but states it is located on the parcel that is shown as not a part of this project in Figure 3.0-2. The comment further states that the location of the residence is inaccurately described as the “unpaved portion of Deerfield Drive” and offers suggested language revisions to this paragraph. The indicated text in the Draft EIR has been revised. The reader is referred to Section 4.0, Minor Revisions to the EIR. Response 31-93: The commenter references mitigation measure MM 4.14.1 in Section 4.14, Greenhouse Gases and Climate Change, on page 4.14-17 of the Draft EIR. The comment states that they are unclear as to whether this measure requires a minimum 15 percent reduction in current Title 24, Part 6 standards or from future energy efficiency standards that are in effect at the time of building permit issuance. The commenter further suggests revised language for the measure to provide clarification. Coldstream Specific Plan Town of Truckee Final Environmental Impact Report March 2014 3.0-210 3.0 EVALUATION OF PROJECT MODIFICATIONS AND EIR COMMENTS AND RESPONSES The indicated text in the Draft EIR has been revised. The reader is referred to Section 4.0, Minor Revisions to the EIR. Response 31-94: The commenter makes reference to Section 6.0, Alternatives to the Project, in the Draft EIR and to their general comment contained in their comment letter related to an additional alternative. The commenter requests that the EIR be augmented to include an alternative to the proposed project that would allow for a maximum of 300 dwelling units, including a maximum of an additional 75 secondary dwelling units, and 30,000 square feet of commercial uses. The commenter further requests that this alternative be analyzed using the locally valid trip generation rates used in the Town of Truckee General Plan EIR and ITE trip generation rates. The commenter is referred to Response 31-2. Response 31-95: The commenter includes a memorandum attached to the Taylor & Wiley letter dated August 26, 2011, prepared by Chris Breiland and Alan Telford of Fehr & Peers, and summarizes Fehr & Peers’ initial review of the transportation analysis conducted as part of the Coldstream Project (PC-1) EIR in support of transportation and circulation related comments provided by Taylor & Wiley. The memorandum states the following: • The technical analysis contained in the transportation section of the EIR relies on some very conservative assumptions. • The use of these assumptions makes the project impacts appear much worse than they would be if the more accurate and locally valid assumptions from the General Plan EIR analysis or the Town TransCAD model were used. • The Draft EIR should identify the Coldstream project as being held to a much more rigorous standard than was assumed in the General Plan EIR analysis, TransCAD model development, and AB 1600 Fee Program. The memorandum further states that there should be no project-related impacts to SR 89 South/Donner Pass Road based on the thresholds of significance identified on page 4.2-25 of the Draft EIR (5 percent increase in trip generation standard) and reiterated on page 4.2-56 of the Draft EIR. The memorandum further states that Option 1 does not result in an existing plus project (project-specific) impact at the I-80 Westbound Ramps/Donner Pass Road intersection as noted on page 4.2-56 of the Draft EIR, and therefore mitigation measure MM 4.2.2b related to the upfront requirement to build the roundabout at this intersection is not applicable and should be removed. The memo acknowledges cumulative impacts at this intersection under Option 1 and the requirement for the project to pay its fair share of traffic impact fees to help fund the roundabout construction is warranted. The commenter is referred to Response 31-44, 31-45, and the revised traffic impact analysis provided in Appendix B of this document. Town of Truckee Coldstream Specific Plan March 2014 Final Environmental Impact Report 3.0-211 3.0 EVALUATION OF PROJECT MODIFICATIONS AND EIR COMMENTS AND RESPONSES Response 31-96: The commenter includes an attachment to the Fehr & Peers memorandum that is an additional memorandum prepared by LSC Transportation Consultants dated April 20, 2006, documenting the development of a computer-based transportation model for the Town of Truckee (TransCAD) and presents an explanation of the development of land use quantities used in the model. The Draft EIR traffic analysis and the revised traffic analysis provided in Appendix B of this document is consistent with the Town’s standards for traffic impact analyses for projects. Coldstream Specific Plan Town of Truckee Final Environmental Impact Report March 2014 3.0-212 3.0 EVALUATION OF PROJECT MODIFICATIONS AND EIR COMMENTS AND RESPONSES Town of Truckee Coldstream Specific Plan March 2014 Final Environmental Impact Report 3.0-213 3.0 EVALUATION OF PROJECT MODIFICATIONS AND EIR COMMENTS AND RESPONSES Letter 32 Douglas Creech Response 32-1: The commenter asks that the Town consider alternative options 2, 3, and 4 rather than Option 1, as Option 1 does not comply with the 2025 General Plan and it unnecessarily impacts existing and future Deerfield/Coldstream residents. The commenter is referred to Section 3.2, Modifications to Project Characteristics, of this document that identifies modification of the project design since release of the Draft EIR. The now proposed Options A and B consist of reduced development potential as compared to the originally proposed Coldstream Specific Plan (see Figures 3.0-1 and 3.0-2). Both options reduce the extent of development on the site. Option A would retain the open roadway connection to Deerfield Drive, but would modify the site design to provide a circuitous roadway system to discourage vehicle trips that pass through the site to access Deerfield Drive and State Route 89 south of Interstate 80. The reduced development intensity and site design would reduce the average daily traffic one-way trips on Deerfield Drive east of the project site to 950 trips (as compared to the originally proposed Coldstream Specific Plan that would generate 2,340 trips). Option B would consist of an emergency-only access to Deerfield Drive and the development of a neighborhood park at this location. The Draft EIR identified a significant and unavoidable impact regarding General Plan Circulation Element consistency, but it was only found to be significant and unavoidable for Options 2, 3, and 4 (see also the General Plan consistency analysis provided in Appendix B of the Draft EIR). The newly proposed Option B would also result in a significant and unavoidable impact regarding General Plan Circulation Element consistency, as this option does not provide a through roadway connection to Deerfield Drive east of the project site. The physical effects of connecting Deerfield Drive with the project site as a through roadway have been analyzed in the various technical sections of the Draft EIR and the revised Traffic Impact Analysis prepared for Options A and B, and no new significant environmental effects were identified. Response 32-2: The commenter asks that traffic from the proposed project not be placed on Deerfield Drive. This comment is noted. The commenter is referred to Response 32-1. Coldstream Specific Plan Town of Truckee Final Environmental Impact Report March 2014 3.0-214 4.0 MINOR REVISIONS TO THE DRAFT EIR 4.0 MINOR REVISIONS TO THE EIR 4.1 INTRODUCTION This section includes minor edits to the Draft EIR and Partially Revised Draft EIR. These modifications resulted from responses to comments received during the Draft EIR and Partially Revised Draft EIR public review periods as well as staff-initiated changes. Revisions herein do not result in new significant environmental impacts and do not constitute significant new information, nor do they alter the conclusions of the environmental analysis. Changes are provided in revision marks (underline for new text and strikeout for deleted text). 4.2 MINOR CHANGES AND EDITS TO THE EIR 1.0 INTRODUCTION The following text changes have been made to page 1.0-2, second paragraph, of the DEIR: Town of Truckee Ministerial Approvals: • Improvement Plans • Grading permits • Encroachment permits • Occupancy permits • Building permits The following text changes have been made to pages 1.0-10 through -11 of the DEIR: TABLE 1.0-1 NOP COMMENTS RECEIVED AND REFERENCES TO REPRESENTATIVE INFORMATION IN THIS EIR Hydrology and Water Quality Habitat buffers and building setbacks should be increased beyond 50 feet along Cold Creek to allow for a wider stream zone. Impacts to Cold Creek from the proposed project are discussed in Section 4.7, Hydrology and Water Quality. Mitigation measures are incorporated where impacts to the creeks and to the project uses are identified. The proposed replacement of the Cold Creek Bridge should be lengthened and an inset floodplain constructed and vegetated to reduce flood and erosion hazards as well as to improve habitat. See above. The proposed project should include a stormwater management plan. As stated in Section 4.7, Hydrology and Water Quality, a stormwater pollution prevention plan is required prior to site disturbance. The water setback should be increased to 100 feet to mitigate for flooding. See above. The watershed upstream of the project is “severely impaired and is incapable of slowing runoff.” The resulting “severe flood risk” should be addressed in the EIR. Flooding impacts as a result of the existing condition of Cold Creek and Donner Creek are addressed in Section 4.7, Hydrology and Water Quality. The existing drainage condition of the two creeks was considered. Town of Truckee Coldstream Specific Plan March 2014 Final Environmental Impact Report 4.0-1 4.0 MINOR REVISIONS TO THE EIR Impacts on streams, ponds, and wetlands should be included in the study. Impacts to these resources are addressed in both Section 4.7, Hydrology and Water Quality, and Section 4.8, Biological and Natural Resources. EIR should address potential impacts to the pond to the southwest from increased ease of access, increased use of recreational facilities, and potential hazards from future residents. Increased impacts on recreational resources are a required consideration in EIRs (see Section 4.11, Community Services). Additionally, see Section 4.7, Hydrology and Water Quality, for a discussion of water quality impacts on these ponds from the proposed project. It should be determined whether the proposed project is subject to Clean Water Act Section 401 Water Quality Certification. Discussion of regulations and programs to which the proposed project is subject is included in Section 4.8, Biological and Natural Resources. Quantification of water quality impacts should be as definitive as possible, using appropriate modeling and adequate data. Section 4.7, Hydrology and Water Quality, includes as much quantification of water resource impacts as possible under the type of EIR prepared. In the case of the park uses and creek/pond enhancements, sufficient detail was not available to produce a project-level analysis. These features were addressed programmatically in this EIR. Cumulative water quality impacts should be addressed in the EIR. Section 4.7, Hydrology and Water Quality, includes a discussion of cumulative water quality impacts resulting from the proposed project combined with anticipated growth in the Town of Truckee. All affected waters should be identified by the EIR, including identification of Water Board jurisdiction, acreage affected, and linear feet impacted. Any affected waters, including a wetland delineation, are included in Section 4.7, Hydrology and Water Quality, and Section 4.8, Biological and Natural Resources. Isolated wetlands or other waters not subject to federal jurisdiction and the projected reach of floodwaters during a 24-hour storm event with a 100-year return frequency for all surface water bodies should be included in the analysis. The commenter is referred to Section 4.7, Hydrology and Water Quality, regarding water resources, and Section 4.8, Biological and Natural Resources, regarding wetlands. Construction-related direct impacts to surface waters will likely require Waste Discharge Requirements. The commenter is referred to Section 4.7, Hydrology and Water Quality, regarding water resources. Principles of avoidance required of federal CWA Section 404(b) (1) guidelines should be considered. The commenter is referred to Section 4.7, Hydrology and Water Quality, regarding water resources. Any discharge of waste earthen materials or other project- related pollutants to any surface waters other than in properly managed stormwater conveyance is prohibited. The commenter is referred to Section 4.7, Hydrology and Water Quality, regarding water resources. The EIR should include a [U.S. Army] Corps-verified wetland delineation, including measures to prevent discharge of pollutants to wetland areas. The EIR includes a wetland delineation for both on- and off-site impacts (see Section 4.7, Hydrology and Water Quality, and Section 4.8, Biological and Natural Resources). Water quality is addressed in Section 4.7. Low impact development (LID) techniques are recommended. The commenter is referred to Section 4.7, Hydrology and Water Quality, regarding water resources.

The Open Space Management Plan must be expanded to include existing conditions and to address integrity of preserved and enhanced areas. The open space management plan is not an aspect of the EIR. However, impacts to preserved and enhanced areas are addressed in Section 4.8, Biological and Natural Resources. EIR should address impacts to wildlife, including impacts from residents’ pets entering the State Park and human-bear interactions. The commenter is referred to Section 4.8, Biological and Natural Resources. Plant species table should be split to show acceptable species on one and species to avoid on another. The proposed change would have no functional effect on the environmental impact of the proposed project as stated in the EIR, as the same plants would be discouraged. Cirsium sp. should be eliminated from the restoration plan palette since many species of this plant can be invasive. Invasive species have been considered in Section 4.8, Biological and Natural Resources. A mitigation measure has been included to prevent planting of this particular genus. The proposed project will require a Timberland Conversion and Timber Harvest Plan, as per California Code of Regulations, Section 1103. Mitigation measures included in Section 4.8, Biological and Natural Resources, require such a plan if timber is to be removed for sale. Impacts on wildlife travel should be studied. Impacts to movement corridors are addressed in Section 4.8, Biological and Natural Resources.

In addition, inclusion of the CH property in the proposed project provides the opportunity for an integrated master plan for the area and eliminates the possibility of creating a remnant incompatible parcel at the west end of Deerfield Drive. The project applicant acquired the property that formerly housed Madigan’s Restaurant and demolished the vacant building in an effort to improve the viability of the proposed commercial uses. Enhancements to Pond Areas, Cold Creek, and Donner Creek A major component of the proposed Coldstream Specific Plan is enhancement of former mining pond areas and restoration of Cold Creek and Donner Creek. Preservation, restoration, and enhancement opportunities are shown in Figure 3.0-7 and Figure 3.0-8 and are summarized below: • Recontouring of pond fringe areas to allow for softer slopes, which improve vegetative habitat for wildlife and the general water quality of the ponds. • Construction of a .65+ acre wetland which allows for seasonal wetland habitat. • Removal of large industrial berms separating pond areas to create a larger pond surface area and habitat opportunities. • Creation of habitat “islands” to attract local wildlife and migratory waterfowl. • Restoration and enhancement of the section of Cold Creek along the Coldstream and State Park properties. Improvements would reduce erosive material along the stream banks and enlarge the stream channel. The improvements would also provide downstream water quality benefits in Donner Creek and the Truckee River. • Replacement of existing Cold Creek Bridge to improve free flow of the creek and reduce the erosive effects of backwater on creek banks. • Proposed construction of a pedestrian bridge crossing of Cold Creek located north of the vehicular bridge. • Creation of an outfall structure to regulate and maintain water levels in the southern pond (Figure 3.0-9). The outfall structure is proposed to be installed concurrent with enhancement and restoration efforts for the pond and open space areas (as a part of Phase II). It is considered an enhancement (not necessary) for the project because it is intended to maintain a more stable water surface elevation in the pond area which is currently being maintained by a small beaver dam/earthen dam. The outfall structure would be engineered to minimize seepage and protect against instability in order to maintain the hydrologic regime of the existing wetlands. Existing drainage patterns would be maintained with no diversion of flow in order to protect the integrative nature of wetland and floodplain communities. Town of Truckee Coldstream Specific Plan March 2014 Final Environmental Impact Report 4.0-7 4.0 MINOR REVISIONS TO THE EIR The following text changes have been made to page 3.0-40, last paragraph, of the DEIR: Recreational Trails A variety of recreational trails are proposed in the Coldstream Specific Plan. These trails are intended to serve as recreational connections to the primary Class I and Class III trail facilities that connect the project site to Donner Memorial State Park and the larger Truckee community. Recreational trails may consist of a variety of earthen and soft surface trails ranging in width from 2 4 to 8 feet. The following text changes have been made to page 3.0-47 of the DEIR: Figure 3.0-17 has been revised to state “Connect to existing 6″ sewer line” rather than 8″ on the western portion of the project site. See the following page for the corrected figure.

Overhead electrical transmission lines are located within the existing Deerfield Drive right-of- way north of the project site. Electrical service is discussed further in Section 4.12, Utilities and Service Systems. Natural Gas and Other Gas Facilities Southwest Gas Corporation provides gas service to the project site. Natural gas is available from a 6-inch polyethylene gas main within the Deerfield Drive right-of-way. Additionally, Kinder Morgan operates a liquid petroleum natural gas pipeline located along the northern boundary of the project site. Natural gas service is discussed further in Section 4.12, Utilities and Service Systems. The following text changes have been made to page 3.0-49, third paragraph, of the DEIR: SOIL IMPORT As part of site preparation, approximately 60,000 cubic yards of soils would be imported to the project site. The soil is anticipated to be imported from Teichert Aggregates’ Martis Valley Plant, which is licensed and permitted for excavation processing and trucking. Soil import and earthwork is anticipated to occur during Phase I of the project. The soil is needed to establish subgrade for roadways, driveways, and building pads. Existing low-lying areas that were previously graded for aggregate mining would be filled as necessary to achieve the minimum required gradients for roadway access and utility infrastructure and would be in compliance with regulatory agencies. Imported fill material would be placed at various locations throughout the project area Lakeside Residential area and Forest Residential area. In accordance with the use permit for Teichert Aggregates’ Martis Valley Plant, all excavated material would meet or exceed regulatory requirements for containment level and compliance before it is imported to the project site. Material that will be exported from the adjacent California State Park Floodplain Creation project to the Stonebridge site excavated from floodplain creation in the California State Parks’ reach will be processed on the immediately adjacent disturbed area on the project property, and approximately 7,000 yards of material (clean gravels and sands) will be transferred to their ownership for later use. The transport of this material is less than 1/4 mile and is internal to the project site. The following text changes have been made to page 3.0-51, third paragraph, of the DEIR: OFF-SITE UTILITY IMPROVEMENTS The following utility improvements would occur off site, but have been included in the environmental analysis: Town of Truckee Coldstream Specific Plan March 2014 Final Environmental Impact Report 4.0-11 4.0 MINOR REVISIONS TO THE EIR • Water, electric, telephone, and cable underground improvements within Coldstream Road • Water improvements within Donner Pass Road and Deerfield Drive • Realignment of existing utilities at the intersection of Donner Pass Road and Coldstream Road • Extension and/or upsizing of overhead telephone and cable lines along Deerfield Drive • Sewer pump station improvements at existing North Donner Pump Station No. 1A (near the Chevron Station) • Sewer force main improvements along Deerfield Drive The following text changes have been made to page 3.0-57 of the DEIR: SCO Planning & Engineering, Kenkay Associates Associations, and Ward-Young Architecture & Planning. 2009. Coldstream Specific Plan. 4.0 INTRODUCTION TO THE ANALYSIS AND ASSUMPTIONS USED The following text changes have been made to page 4.0-3, third paragraph, of the DEIR: To accommodate construction of the proposed project, approximately 60,000 cubic yards of soil would be imported to the project site. Approximately 5,000 truckloads of soil would be brought to the project site over a period of 15 days from Teichert’s Martis Valley Plant located approximately 5.2 miles away. The soil import would occur during Phase I of the proposed project. Material from the adjacent State Parks property would also be imported to the project site as part of Cold Creek restoration and enhancement work that will occur on the State Parks property. The stockpile would be located on the southwest corner of the proposed project site in the Village Green area. 4.1 LAND USE The following changes have been made to page 4.1-5 of the DEIR: Figure 4.1-2 has been modified to include the northern portion of the Specific Plan site. See the following page for the corrected figure.

A total of 70 50 acres is assigned for development of all allowed uses on the site in recognition of the physical constraints to development that exist over much of the site’s area. This acreage is a guideline to be used in specific plan development and may vary based on the results of detailed studies completed prior to site development. The following text changes have been made to page 4.1-18, second paragraph, of the DEIR: Donner Memorial State Park is located immediately to the west of the project site separated by a 60-foot-wide Nevada County road easement for Coldstream Road and adjacent land with a pond to the southwest of the project. The park contains a campsite approximately 150 feet from the project site’s western boundary. The closest land use within the project site to the campgroundsite area is Village Green Residential Small Lot. The following text changes have been made to page 4.1-21 of the DEIR: MM 4.1.3 The project applicant shall modify the project design western buffer and residential parcels along the Village Green Residential Small Lot area in the following manner as shown in Figure 4.1-5: o Eliminate residential lots along the western project boundary adjacent to Donner State Memorial State Park. o Increase the size of the buffer in this area to provide a 100-foot setback from the western property line. o Provide a 6-foot durable (winter-resistant) fence along the western boundary to the recreation parcel with no gates or openings (except as noted below). Final design of the fence shall be approved by the Town Planner prior to installation. o Provide a gated access point at the recreation parcel to the California Department State Parks and Recreation parcel immediately to the west for use only by the California Department State Parks and Recreation. State Parks and Recreation shall be provided a legally recorded, deeded easement for access across the Coldstream development property. Timing/Implementation: Prior to approval of tentative maps for the Village Green Residential Small Lot area and Recreation parcel Enforcement/Monitoring: Town of Truckee Planning Division Implementation of the above mitigation measure would expand the buffer area between Donner State Memorial State Park campsites and residential uses to a total of 250 feet and would provide a barrier to avoid trespass from the residential area into the park. This additional buffering and barrier provision would mitigate this impact to less than significant. Town of Truckee Coldstream Specific Plan March 2014 Final Environmental Impact Report 4.0-15 4.0 MINOR REVISIONS TO THE EIR 4.2 TRANSPORTATION AND CIRCULATION The following text changes have been made to page 4.2-5, second paragraph, of the DEIR: Deerfield Drive While originally a through roadway, currently Deerfield Drive consists of two sections, separated by Donner Creek. To the east of the creek, it is a two-lane roadway extending westward from SR 89 South for approximately one-half mile. Near SR 89 South, Deerfield Drive serves commercial land uses including the Crossroads Center, while farther west the lanes narrow slightly as the roadway serves a residential neighborhood and church. Adjacent to the northern edge of the Crossroads Center, Deerfield Drive is improved to a 46-foot cross section with curb, gutter, and attached sidewalks. Adjacent to the Boulders condominium development and the Inn at Truckee, the total pavement width is about 36 feet, and sidewalk, curb, and gutter are provided along the north side of the street. This segment of Deerfield Drive has a summer PM peak hour total two-way volume of about 108 110. A rural residential street standard is provided through the residential neighborhood to the west, with approximately 24 feet of pavement width, graveled shoulders, and a posted speed limit of 25 miles per hour. This segment of Deerfield Drive has a summer PM peak hour total two-way volume of up to 63 60. To the west of the creek, Deerfield Drive consists of a cul-de-sac roughly 650 feet in length. It provides access from Coldstream Road to a fast-food restaurant with drive-through, a service station, and commercial office space. The following text changes have been made to page 4.2-27, second paragraph, of the DEIR: It is important to note that a total of four project options were evaluated based on whether the Deerfield Drive extension would provide full access or emergency vehicle access only and different configurations of the proposed project’s internal roadway network. The four options (as depicted in Figures 3.0-11 through 3.0-14) are defined as: The following text changes are made to mitigation measures MM 4.2.2a through c starting on Draft EIR page 4.2-57: MM 4.2.2a One of two options shall be implemented for all project roadway alignment options to improve the LOS at the SR 89 South/Donner Pass Road/Frates Lane intersection: • Signal Improvements: Either provision of an eastbound right-turn overlap phase or reconfiguration of the northbound approach to provide an exclusive left-turn lane and a shared through/right-turn lane would improve the total intersection LOS to an acceptable LOS D in 2010, with or without the project. The level of traffic growth that can be accommodated in the short term before both of these improvements would be needed was evaluated. Based on the results, the total intersection PM peak hour traffic volumes can increase by about 7 percent before both improvements would be needed. In 2030, both improvements would be needed in order to achieve an acceptable LOS D, with or without the project. Or Coldstream Specific Plan Town of Truckee Final Environmental Impact Report March 2014 4.0-16 4.0 MINOR REVISIONS TO THE EIR • Roundabout: Constructing a two-lane roundabout with double-lane northbound, westbound, and eastbound approaches, and a single-lane southbound approach, would improve LOS at the intersection to a worst movement LOS E or better with the proposed project. This analysis assumes a 90-foot central island diameter for the no project alternative, as well as Options 2 through 4. For Option 1, a slightly larger roundabout (100-foot central island diameter) is necessary to attain LOS E on all approaches. While either option would provide acceptable LOS conditions, the roundabout would provide shorter queue lengths and less impact on traffic flow at nearby driveways and intersections. However, A detailed roundabout design will be required to evaluate right-of-way and utility relocation requirements. The signal improvements are considered short-range improvements, which are not included in the Town of Truckee Traffic Impact Fee Program. The project applicant shall perform a detailed intersection analysis, at the applicant’s expense, to determine the combination of short-range improvements that will maximize intersection capacity at this location. The detailed analysis may identify other combinations of re-striping and/or signal phasing improvements beyond those identified in this study which will maximize the short-range future capacity of this intersection within the existing roadway widths. The intersection improvements identified through the detailed intersection analysis will be determined during review of the improvement plans, and approved by the Town Engineer, prior to building permit issuance. Prior to temporary or final Certificate of Occupancy of any buildings, the project applicant shall implement the approved intersection improvements, at the applicant’s expense. The project applicant may request reimbursement of a fair-share portion of the short-range improvements from future discretionary Category 3 and 4 projects (as defined by General Plan Table CIR-6) that add traffic to the SR 89 South/Donner Pass Road/Frates Lane intersection. It is the intent of the Town to include language requiring such projects to reimburse this project for their fair-share cost of the short-range improvements as a part of the future land use conditions of approval; however, it will be the responsibility of this project applicant to request that such a condition be placed on applicable projects prior to project approval. Provision of a two-lane roundabout is considered a long-range improvement, and it is included in the Traffic Impact Fee Program. The proposed project’s payment of Traffic Impact Fees would mitigate LOS impacts to this intersection only for the roundabout option, not for the signal improvements option. It should be noted that the proposed project contributes the following percentages to total future growth in summer PM peak hour traffic at this intersection between 2010 and 2030: • Option A 1: 1917% • Option B s 2, 3, and 4: 2119% Timing/Implementation: Prior to issuance of building recordation of final map Enforcement/Monitoring: Town of Truckee Engineering Division Town of Truckee Coldstream Specific Plan March 2014 Final Environmental Impact Report 4.0-17 4.0 MINOR REVISIONS TO THE EIR MM 4.2.2b One of two options shall be implemented to improve the LOS at the I-80 Westbound Ramps/Donner Pass Road (western interchange) intersection for both options under 2030 conditions and only Option B for 2010 conditions: • Lane Improvements: Provision of an acceleration lane along Donner Pass Road for left turns made from the off-ramp would improve the worst movement LOS to an acceptable LOS D or better in 2030 with the project alternatives. At least 300 feet of acceleration lane length would need to be provided, plus a 180-foot taper. As the distance from the beginning of the acceleration lane to the existing overpass bridge is about 275 feet, the acceleration lane would extend along the overpass. The existing pavement width on the overpass is about 40 feet. As the existing overpass does not provide adequate pavement width to accommodate two travel lanes, the potential acceleration lane, and the existing Class II bike lane and sidewalk, this improvement may not be feasible. Or • Roundabout: Constructing a single-lane roundabout would provide a worst movement LOS C or better at the intersection in 2030 with the project. A preliminary design and layout for this roundabout was prepared by LSC and is presented in Draft EIR Figure 4.2-7. An inscribed circulating diameter of 120 feet is assumed, with a circulating roadway width of 20 feet. The access leg to the Caltrans staging area will be configured in such a way that it discourages use by the general public but allows full access by authorized equipment and vehicles. Considering the shorter queue lengths that can be achieved by a roundabout at this location, as well as the disadvantages of the pavement widening required under the acceleration lane alternative, construction of a roundabout is the recommended mitigation measure. Furthermore, a roundabout would improve driver sight distance conditions by reducing traffic speeds along Donner Pass Road. Improvements to this intersection are included in the Town of Truckee Traffic Impact Fee Program. The project contributes the following percentages in total future growth in summer PM peak hour traffic at this intersection between 2010 and 2030: Option 1: 51% Options 2–4: 67% The details of intersection improvements will be determined during review of the improvement plans, and approved by the Town Engineer, prior to building permit issuance. Prior to temporary or final Certificate of Occupancy of any buildings, the project applicant shall implement the approved intersection improvements, at the project applicant’s expense. The project applicant shall will be reimbursed a fair-share portion of for the improvements pursuant to Town standards.

A preliminary design of this roundabout is shown in Figure 4.2-8. An inscribed circulating diameter of 110 feet is assumed, with a circulating roadway width of 20 feet. Improvements to this intersection are included in the Town of Truckee Traffic Impact Fee Program. The project contributes the following percentages in total future growth in summer PM peak hour traffic at this intersection between 2010 and 2030: Option 1: 65% Options 2–4: 74% The details of intersection improvements will be determined during review of the improvement plans, and approved by the Town Engineer, prior to building permit issuance. Prior to temporary or final Certificate of Occupancy of any buildings, the project applicant shall implement the approved intersection improvements, at the project applicant’s expense. The project applicant shall will be reimbursed a fair-share portion of for the improvements pursuant to Town standards. Timing/Implementation: Prior to issuance of building permits recordation of final map Enforcement/Monitoring: Town of Truckee Engineering Division The following text changes are made to mitigation measure MM 4.2.3a and b on Draft EIR page 4.2-65: MM 4.2.3a The project applicant shall construct an adequately sized 50-foot southbound left-turn lane at the Coldstream Road/Deerfield Drive intersection that will not obstruct traffic as well as provide pavement markings and signage indicating “Do Not Block.” MM 4.2.3b Should the Town Engineer determine it necessary, the project applicant shall fund the installation of a “Do Not Block” box to be painted in the intersection of SR 89/Deerfield Drive accompanied by appropriate signage. This mitigation measure only applies to Option A. pavement markings and signage indicating “Do Not Block” at the SR 89/Deerfield Drive intersection. The following text changes are made to Impact 4.2.5 on Draft EIR page 4.2-66: Town of Truckee Coldstream Specific Plan March 2014 Final Environmental Impact Report 4.0-19 4.0 MINOR REVISIONS TO THE EIR Impact 4.2.5 Implementation of project would not result in a traffic condition that would conflict with General Plan Circulation Element Policy P2.2 and Policy P2.4. However, Option B s 2, 3, and 4 would create a development that is not integrated into the circulation network, as required by General Plan Circulation Element Policy 2.4 and Goal CIR-4. The following text changes are made to mitigation measures MM 4.2.10a, b and c on Draft EIR pages 4.2-70 and -71. Mitigation measure MM 4.2.10c was deleted based on redesign of the project: MM 4.2.10a Existing brush along Donner Pass Road in the southeast quadrant of the I-80 Westbound Ramps/Donner Pass Road intersection shall be maintained trimmed or removed in order to increase the sight distance from the off-ramp looking to the east. In addition, the final landscaping plans for the project shall provide adequate driver sight along the Primary Road through the site. during the winter season, snow berms shall be removed from this area. MM 4.2.10b If Deerfield Drive is opened to through traffic into/out of the project site (Option A1), trees obstructing the sight of the Class I trail as it crosses Deerfield Drive immediately east of the current western terminus of Deerfield Drive, as it exists immediately east of the project site, shall be removed or trimmed to allow for adequate site distance. This includes any vegetation under those trees which would impede driver sight distance. Tree/vegetation removal shall be conducted to the extent that an unobstructed sight line exists for a distance of at least 275 feet.

The significant increases in traffic noise levels occur along Coldstream Road from Deerfield Drive to the project site access where a 10 dBA increase in the CNEL occurs, and along Deerfield Drive from 1,000 feet west of State Route (SR) 89 to the end of the pavement where the increase in traffic noise levels is 5 6 dBA CNEL. Table 4.3-10 shows the increase in existing traffic noise levels without the Deerfield connector (Options 2, 3, and 4). The significant increases in traffic noise levels occur along Coldstream Road from Donner Pass Road to Deerfield Drive and from Deerfield Drive to the project site access. The increases in traffic noise levels are 4 dBA and 11 dBA, respectively. Table 4.3-11 shows the increase in year 2030 traffic noise levels with the Deerfield connector (Option 1). The significant increases in traffic noise levels occur along Coldstream Road from Deerfield to the project site access where a 9 dBA increase in the CNEL occurs, and along Deerfield Drive from 1,000 feet west of SR 89 to the end of the pavement where the increase in traffic noise levels is 5 6 dBA CNEL. The following text changes have been made to page 4.3-22, second paragraph, of the DEIR: Activities associated with construction would result in elevated noise levels within the immediate vicinity of the project site, including some construction noise associated with the construction of possible off-site Class I trails along Donner Pass Road and portions of Deerfield Drive and a potential sidewalk along the south side of Deerfield Drive under Option 1 (as described in mitigation measure MM 4.2.10c in Section 4.2, Transportation and Circulation). Activities involved in construction would typically generate maximum noise levels ranging from 85 to 90 dB at a distance of 50 feet. Construction activities could result in periods of elevated noise levels at existing residences located along Deerfield Drive as well as to campers at Donner Memorial State Park. Though construction would occur for a limited period of time and would result in temporary intermittent increases in noise, anticipated noise levels would exceed standards for residential uses. Since existing residents along Deerfield Drive as well as campers at Donner Memorial State Park could be exposed to construction noise in excess of standards, construction noise impacts are considered potentially significant. The following text changes have been made to page 4.3-23 of the DEIR: Temporarily Temporary vibration may occur on the project site during construction. The presence of heavy equipment on the site and techniques used for soil compaction during site preparation could cause vibration on the site and may be detectible at distances within 50 feet. While vibrations may be felt, the vibration levels anticipated in association with construction are not expected to result in any type of structural damage to existing buildings in the vicinity of the project site. Therefore, construction vibration impacts are considered less than significant. Mitigation Measures None required. Town of Truckee Coldstream Specific Plan March 2014 Final Environmental Impact Report 4.0-23 4.0 MINOR REVISIONS TO THE EIR Exterior Traffic Noise Impacts at the Project Site for All Options Impact 4.3.3 Implementation of the proposed Coldstream Specific Plan would expose proposed residential uses on the project site to noise levels in excess of Town of Truckee noise standards. This impact is considered potentially significant. The main source of traffic noise near the project site is I-80 to the north. Based on the analysis shown in Table 4.3-3, the predicted future I-80 traffic noise levels could exceed acceptable levels for the proposed Forest Residential uses on the northern portion of the project site. Although the General Plan depicts the project site as being located within the 70 dBA contour, predicted noise levels, which account for intervening buildings and topography, are approximately 63 dBA to 64 dBA CNEL at a distance of 550 feet from the centerline of I-80. The following text changes have been made to pages 4.3-24 through -25 of the DEIR: Mitigation Measures MM 4.3.3 A noise berm with a minimum height of 6 feet to 7 feet shall be constructed along the north lot lines of the Forest Residential portion of residential portion of the site south of I-80. The berm shall be landscaped in accordance with the Town’s landscaping standards. Final review and approval of the landscaped berm shall occur when a tentative map for the Forest Residential residential area of the proposed Coldstream Specific Plan south of I-80 has been completed and will be incorporated into the design of the Coldstream Specific Plan Interstate 80 Buffer in order to blend with the adjacent environment. Timing/Implementation: Upon completion of tentative map for the Forest Residential residential area of the proposed Coldstream Specific Plan south of I-80/as a condition of approval Enforcement/Monitoring: Town of Truckee Planning Division Implementation of mitigation measure MM 4.3.3 would reduce noise impacts from I-80 to proposed residences on the project site to a less than significant level. Interior Traffic Noise Impacts on the Project Site for All Options Impact 4.3.4 Implementation of the proposed Coldstream Specific Plan would result in interior exterior traffic noise levels below 65 dBA CNEL for all options. However, interior noise levels could exceed 45 dBA CNEL if doors and windows on residential uses are open. Therefore, this impact is considered potentially significant. In addition to traffic from I-80, uses on the project site would also be exposed to noise generated by internal traffic on the project site. Typical construction practices, including building materials, dual-pane windows, and building orientation, will result in an exterior-to- interior reduction in traffic noise levels of 20 dB to 25 dB. Predicted traffic noise levels at proposed residential uses are not expected to exceed 65 dBA CNEL. Therefore, interior noise levels are anticipated to comply with the 45 dBA CNEL standard, provided that windows and Coldstream Specific Plan Town of Truckee Final Environmental Impact Report March 2014 4.0-24 4.0 MINOR REVISIONS TO THE EIR doors are in the closed position. However, if residents wish to leave windows and doors open, the interior noise levels may exceed 45 dBA CNEL. Therefore, this may be a potentially significant impact. Mitigation Measures MM 4.3.4 Residential uses designated as Village Mixed Use Commercial and Forest Residential shall be designed to orient noise-sensitive sleeping areas and living areas away from I-80 to allow residents to open windows and achieve an interior noise level of 45 dBA CNEL. AND An acoustical analysis shall be provided to determine if interior noise levels can comply with an interior noise level standard of 45 dBA CNEL with the windows and/or doors in the open position. The acoustical analysis shall include recommendations for reducing any interior noise above 45 dbA. These recommendations shall be implemented. Timing/Implementation: Prior to approval of any building permits for Village Mixed Use Commercial and Forest Residential uses Enforcement/Monitoring: Town of Truckee Planning Division Implementation of mitigation measure MM 4.3.4 would reduce interior noise levels for residential uses on the project site to a less than significant level. Traffic Noise Impacts at Existing Residences Due to Increased Traffic from the Project Site for Option 1 Impact 4.3.5 Construction of the proposed Coldstream Specific Plan associated with Option A1 with open access to Deerfield Drive would result in increased noise levels at existing residences along Deerfield Drive. This impact is considered potentially significant. Option 1 includes the Deerfield connector as a part of the project. Based on Table 4.3-9, a 10 dBA increase in the CNEL would occur along Coldstream Road from Deerfield Drive to the project site access, and 5 6 dBA CNEL increase would occur along Deerfield Drive from 1,000 feet west of SR 89 to the end of the pavement. No noise-sensitive uses are located along Coldstream Road. In addition, the traffic noise levels at a distance of 75 feet from the roadway centerline do not exceed the Town of Truckee 60 dBA CNEL noise level standard. Currently, there are existing residences located in close proximity to Deerfield Drive from 1,000 feet west of SR 89 to the existing roadway terminus. The increase in Deerfield Drive traffic noise levels is 5 6 dBA CNEL. Currently, residents along Deerfield Drive are exposed to traffic noise levels of approximately 61 dBA to 62 dBA CNEL due to I-80 traffic. The 5 6 dBA CNEL increase in traffic noise levels from Deerfield Drive is considered to be substantial and results in a potentially significant impact. One can expect a minimum of a 20 dBA exterior to interior traffic noise level reduction at the residences along Deerfield Drive with the windows in the closed position. This would result in interior traffic noise levels of approximately 40 dBA CNEL at residences along Deerfield Drive between SR 89 and approximately 1,000 feet west Town of Truckee Coldstream Specific Plan March 2014 Final Environmental Impact Report 4.0-25 4.0 MINOR REVISIONS TO THE EIR of SR 89. The interior traffic noise level would be approximately 34 dBA CNEL at residences along Deerfield Drive at a point 1,000 feet west of SR 89 to the end of the pavement. One can expect a minimum of a 10 to 12 dBA exterior to interior traffic noise level reduction at the residences along Deerfield Drive with the windows in the open position. This would result in interior traffic noise levels of approximately 50 dBA CNEL at residences along Deerfield Drive between SR 89 and approximately 1,000 feet west of SR 89. The interior traffic noise level would be approximately 44 dBA CNEL at residences along Deerfield Drive at a point 1,000 feet west of SR 89 to the end of the pavement. Although some all residences along Deerfield Drive are currently exposed to traffic noise levels in excess of the Town’s generally accepted exterior noise level standard of 60 dBA CNEL, the traffic noise levels are dominated by and primarily due to I-80 traffic. The project is not expected to result in an increase in traffic noise along I-80. The project will not result in an exceedance of the traffic noise level standards along Deerfield Drive. Mitigation Measure MM 4.3.5 Deerfield Drive shall be resurfaced with rubberized or open-gap asphalt to reduce overall traffic noise levels by approximately 4 dBA. Timing/Implementation: Prior to project occupancy of Phase II Phase I/as a condition of approval Enforcement/Monitoring: Town of Truckee Planning Division and Engineering Division The following text changes have been made to pages 4.3-28 through -29 of the DEIR: Cumulative Increases in Ambient Noise Levels Impact 4.3.9 Implementation of the proposed Coldstream Specific Plan, in combination with existing, approved, proposed, and reasonably foreseeable development, could result in significant traffic noise exposure for existing residents along Deerfield Drive east of the project site under Option 1 (now Option A) roadway design as well as expose future project residents to excessive noise levels under cumulative conditions. This would be a cumulatively considerable impact. The proposed project’s contribution to future cumulative noise levels would be primarily associated with potential increases in vehicle traffic noise along area roadways and stationary noise sources associated with the commercial component of the project. Area roadways primarily affected by the proposed project include portions of Donner Pass Road, Coldstream Road, and Deerfield Drive. While the proposed project may include off- site pedestrian/bicycle improvements to Donner Pass Road and Deerfield Drive, these improvements by their nature as pedestrian/bicycle facilities will generate little additional noise after construction is complete. Predicted future cumulative traffic noise levels with and without implementation of the proposed project are summarized in Tables 4.3-11 (Option 1 – now Option A) and Table 4.3-12 (Options 2, 3, and 4 – now Option B). As depicted, implementation of the proposed project alternatives would result in projected increases of less than 4 dBA along these primarily affected roadway segments, with the exception of Coldstream Specific Plan Town of Truckee Final Environmental Impact Report March 2014 4.0-26 4.0 MINOR REVISIONS TO THE EIR Coldstream Road from Deerfield Drive to the project entrance, which would experience increases up to 11 dBA in exterior traffic noise due solely to traffic on Coldstream Road (Table 4.3-12). The one exception would occur in association with Option 1 A, which includes the Deerfield Drive connection. Coldstream Road from Deerfield Drive to the project entrance is currently a short “stub road” that serves the proposed residential development at the project site. With implementation of the proposed project, the increase in traffic noise along this roadway segment will not affect any existing noise-sensitive receivers, and the background exterior noise levels will continue to be dominated by traffic along I-80. As noted in the discussions for Impacts 4.3.5 and 4.3.6, the traffic noise generated on this roadway segment would not exceed any applicable Town of Truckee exterior noise level standards. Option 1 A includes the Deerfield connector as a part of the project. Based on Tables 4.3-9 and 4.3-10, the significant increases in traffic noise levels occur along Deerfield Drive from 1,000 feet west of SR 89 to the end of the pavement where the modeled increase in Deerfield Drive exterior traffic noise levels is 5 6 dBA CNEL. The overall measured noise levels, shown in Table 4.3-2 for Site B, along this segment of Deerfield Drive are already between 61 dB CNEL and 62 dB CNEL due to I-80 traffic, as compared to the predicted Deerfield Drive noise levels of 54 dB CNEL with implementation of Option 1 A. Therefore, although the increase in traffic volumes along Deerfield Drive would result in changes to the Deerfield Drive exterior traffic noise levels, traffic along I-80 would continue to be the dominant noise source in this area. No noise-sensitive uses are located along Coldstream Road. In addition, the traffic noise levels at a distance of 75 feet from the roadway centerline do not exceed the Town of Truckee 60 dBA CNEL noise level standard as shown in Table 4.3-4. Currently, there are existing residences located in close proximity to Deerfield Drive from 1,000 feet west of SR 89 to the existing roadway terminus. For Option 1 A, which includes the Deerfield Drive connection, the increase in Deerfield Drive traffic noise levels is 5 6 dBA CNEL. Noise levels associated with the commercial portion of the project site would add to the future background noise environment. The potential for this impact is specific to Donner Memorial State Park located to the east of the project site. 4.4 AIR QUALITY The following text changes have been made to pages 4.4-18 to -19 of the Draft EIR: MM 4.4.1b The project applicant shall submit to the NSAQMD for approval of an Off- Road Construction Equipment Emission Reduction Plan prior to groundbreaking, demonstrating that all off-road equipment (portable and mobile) meets or is cleaner than Tier 2 engine emission specifications unless prior written approval for any exceptions is obtained from the NSAQMD. Note that all off-road equipment must meet all applicable state and federal requirements. The project applicant shall submit to NSAQMD for approval an Off-Road Construction Equipment Emission Reduction Plan prior to groundbreaking demonstrating that the heavy-duty (greater than 50 horsepower) off-road vehicles to be used in the construction project, including owned, leased, and subcontractor vehicles, will achieve a project-wide fleet-average 20 percent NOx reduction and 40 percent particulate reduction compared Town of Truckee Coldstream Specific Plan March 2014 Final Environmental Impact Report 4.0-27 4.0 MINOR REVISIONS TO THE EIR to the most recent CARB fleet average at time of construction. Acceptable options for reducing emissions may include use of late-model engines, low-emission diesel products, alternative fuels, engine retrofit technology, after-treatment products, and/or other options as they become available. The plan shall include a comprehensive inventory of all off-road construction equipment, equal to or greater than 50 horsepower, that will be used an aggregate of 40 or more hours during any portion of the construction project. The inventory shall include the horsepower rating, engine production year, and projected hours of use or fuel throughput for each piece of equipment. The inventory shall be updated and submitted monthly throughout the duration of the project, except that an inventory shall not be required for any 30-day period in which no construction activity occurs. At least 48 hours prior to the use of subject heavy-duty off-road equipment, the project representative shall provide NSAQMD with the anticipated construction timeline including start date and name and phone number of the project manager and on-site foreman. Construction contracts shall stipulate the following: • Emissions from on-site construction equipment shall comply with NSAQMD Regulation II, Rule 202, Visible Emissions. • The primary contractor shall be responsible to ensure that all construction equipment is properly tuned and maintained. • Idling times shall be minimized either by shutting equipment off when not in use or reducing the maximum idling time to 5 minutes when not in use (as required by California airborne toxics control measure Title 13, Section 2485 of California Code of Regulations). Clear signage shall be provided for construction workers at all access points. • All construction equipment shall be maintained and properly tuned in accordance with manufacturers’ specifications. All equipment shall be checked by a certified mechanic and determined to be running in proper condition prior to operation. • Utilize existing power sources (e.g., power poles) or clean fuel generators rather than temporary power generators. Timing/Implementation: The Off-Road Construction Equipment Emission Reduction Plan shall be submitted and approved prior to issuance of building permits for the first phase of construction. The plan shall be implemented during all phases of construction. Enforcement/Monitoring: Town of Truckee Planning Division; NSAQMD Coldstream Specific Plan Town of Truckee Final Environmental Impact Report March 2014 4.0-28 4.0 MINOR REVISIONS TO THE EIR The following text changes have been made to page 4.4-21, second paragraph, of the DEIR: Exposure to Wood Smoke from Prescribed Burns at Donner Memorial State Park While not an emission source attributed to the project, future project residents may will be exposed to occasional wood smoke from prescribed fires by California Department of State Parks for areas of Donner Memorial State Park where removal and transport of excess vegetative fuels is not feasible. The occurrence of such events is expected to be infrequent and not an ambient air quality condition in the project area. The following text changes have been made to page 4.4-24, first paragraph, of the DEIR: Implementation of mitigation measure MM 4.4.3a, as well as traffic improvements identified in Section 4.2, Transportation and Circulation, would require preparation of an emissions reduction plan to include NSAQMD-recommended mitigation measures. Implementation of NSAQMD-recommended mitigation measures would result in substantial reductions in project- generated emissions. For instance, prohibiting the use of wood-burning heating devices would reduce combined area-source winter emissions to a total of approximately 30 lbs/day of ROG, 9 lbs/day of NOx, and 0.3 lbs/day of PM10. In total, project-generated winter emissions from both area and mobile sources would be reduced to approximately 84 lbs/day of ROG, 89 lbs/day of NOx, and 224 lbs/day of PM10. Emissions offsets for project-generated emissions of PM10 would also be required, sufficient to meet the requirements of the Town’s Particulate Matter Air Quality Management Plan. With implementation of the above mitigation measure, project-generated emissions would be reduced to below NSAQMD significance thresholds. Mitigation measure MM 4.4.3b would ensure that residents are informed of occasional wood smoke from prescribed fires at Donner Memorial State Park. With mitigation, this impact would be considered less than significant. 4.7 HYDROLOGY AND WATER QUALITY The following text changes have been made to page 4.7-33, last paragraph, of the DEIR: MM 4.7.2b Site development areas (excluding open space and recreation) that are located adjacent to existing or proposed on-site ponds within designated open space areas shall be designed and constructed to direct excess runoff to drain into ponds and shall not discharge directly to existing creeks. Discharge shall be allowed into detention/retention ponds and the storm drain system required under mitigation measure MM 4.7.2a above. This requirement shall be incorporated into drainage improvements identified under mitigation measure MM 4.7.1a. Timing/Implementation: Design of drainage facilities shall be completed prior to approval of site grading and drainage plans. Construction to be completed prior to issuance of building permits.

If the agencies determine that such consultation is required, the applicant will comply with any conditions which result from that consultation. Timing/Implementation: Prior to creek restoration activities Enforcement/Monitoring: Town of Truckee Planning Division 4.9 HISTORIC AND CULTURAL RESOURCES The following text changes have been made to page 4.9-4, first paragraph, of the PRDEIR: Donner Memorial State Park is located adjacent to the western side of the project site. The park contains archaeological resource CA-NEV-13/H, which is listed on the National Register of Historic Places and is also National Historic Landmark #66000218. In addition, the park, along with the Donner (or Pioneer) Monument, is also listed on the California Register of Historical Resources as California Historical Landmark #134. The park memorializes the Donner Party’s 1846–1847 ill-fated attempt to travel over Walker Pass by wagon and the resulting suffering and loss of life. This park offers opportunities for camping, picnicking, boating, fishing, water-skiing, and hiking. In winter, visitors can cross-country ski and snowshoe on trails. The park includes the Emigrant Trail Museum and Pioneer Monument, built to commemorate those who emigrated to California from the east in the mid-1800s. Included in the museum are displays and information about the Donner Party. The park encompasses Scallenberger Ridge to the south of Donner Lake. The Pioneer Monument, Emigrant Museum, and historical Murphy Cabin are located approximately 600 feet to the west of the western boundary of the project site 4.10 VISUAL RESOURCES/LIGHT AND GLARE The following text changes have been made to page 4.10-1, last paragraph, of the DEIR: Uses adjacent to the project site vary from undeveloped open space to urban uses (see Figures 3.0-3 and 4.10-2). On the north, Interstate 80 (I-80) borders the site but is shielded from view by substantial vegetation and stands of trees. There is some commercial development immediately northwest of the project site including two gas stations, a Holiday Inn, and another small motel. In addition, the Deerfield Drive and Boulders residential neighborhoods are located northeast and east of the project site, respectively. These neighborhoods are characterized by older suburban homes, and in the case of Boulders, newer attached residential units. South of the project site are undeveloped, naturally vegetated land and the Union Pacific railroad line.

The following text changes have been made to page 4.10-26, third paragraph, of the DEIR: The existing commercial uses northwest of the project site would not be significantly buffered from the proposed commercial and retail development within the Village Mixed-Use Commercial (MUC) zoning district. The existing uses include two gas stations that are each one story and a Holiday Inn of two three stories (see Figure 4.10-2). The maximum height of the proposed uses within the MUC zoning district would be 50 feet or 3.5 stories. Although the proposed uses could be taller than the existing uses, they would be similar in nature and would be compatible in terms of aesthetics. 4.11 COMMUNITY SERVICES The following text changes have been made to page 4.11-7, last paragraph, of the DEIR: TTPD has mutual assistance agreements with the California Highway Patrol (CHP), which provides policy police protection on all state and county roadways in Nevada County. The CHP and the Town of Truckee Police Department provide reciprocal backup protection as needed. The following text changes have been made to page 4.11-14, third paragraph, of the DEIR: The proposed project would pay a recreation impact fee for each newly created parcel (including residential and nonresidential parcels) rather than dedicating parkland meet its Quimby Act obligations through payment of recreational impact fees and/or dedication of parkland. Additionally, the TDRPD would receive property tax revenue from all types of development on the project site. The recreation impact fee program would help reduce impacts to TDPRD facilities. Therefore, impacts to parks and recreational facilities are considered less than significant. The following text changes have been made to page 4.11-15 of the DEIR: MM 4.11.3.2 Prior to the finalization of exact trail alignments through the project site, the project applicant shall coordinate with California Department of Parks Coldstream Specific Plan Town of Truckee Final Environmental Impact Report March 2014 4.0-32 4.0 MINOR REVISIONS TO THE EIR and Recreation staff and Town staff to ensure compatibility of trail alignment and compatibility of uses on the connected trails. If deemed necessary, trail alignments shall be modified in cooperation with the California Department of Parks and Recreation. Trail connection points to Donner Memorial State Park trails will include signage notifying trail users of their entrance to Donner Memorial State Park and the associated rules and regulations of the park. Timing/Implementation: Prior to finalization of project trail alignments Enforcement/Monitoring: Town of Truckee Planning Division; California Department of Parks and Recreation The following text changes have been made to page 4.11-20, first paragraph, of the DEIR: The TTUSD is authorized by state law (Government Code Section 65995-6) to levy a school facility impact fee. The fee for new residential construction is $2.63 per square foot of residential construction. The fee for commercial construction is $0.42 per square foot. The fees are used for the purpose or of funding the reconstruction or construction of new school facilities. The school facility impact fee schedule is based on current state law and Government Code 65996, which states that the “development impact fees authorized by SB 50 are deemed to be ‘full and complete school facilities mitigation’ for the impact caused by new development on school facilities.” This applies regardless of school capacity or overcrowding issues. 4.12 UTILITIES AND SERVICE SYSTEMS The following changes are made to page 4.12-1, third paragraph, of the DEIR: A portion of Truckee River water is stored in federal and non-federal reservoirs located in California. The federal reservoirs are Lake Tahoe and Prosser Creek, Boca, Stampede, and Martis Creek reservoirs. The non-federal reservoirs (natural lakes with some storage created by man-made dams) are Independence Lake (owned and operated by Sierra Pacific) and Donner Lake (owned and operated by the Truckee Meadows Water Authority Sierra Pacific and the Truckee-Carson Irrigation District). Collectively, these reservoirs are referred to as Truckee River reservoirs. Operation of the reservoirs allows distribution of water in the Truckee River system throughout the year (Bureau of Reclamation, 2008). The following changes have been made to page 4.12-2, second paragraph, through page 4.12-4, fourth paragraph, of the DEIR: TRUCKEE DONNER PUBLIC UTILITY DISTRICT Water service to the project site would be provided by the Truckee Donner Public Utility District (TDPUD). TDPUD operates three two water systems in Truckee: the Hirschdale System, and the Truckee System, and the Lahontan System. The Lahontan System is owned by Placer County Water Agency (PCWA) and is operated by TDPUD under contract with PCWA. In addition to the three systems operated by TDPUD, there are two other water systems within the Truckee, The Donner Lake and Glenshire, and Lake systems, which are owned and operated by other districts, were acquired by TDPUD in 2001 and 2002, respectively, and have both been integrated in TDPUD’s Truckee system. Projects have been under way since 2005 to combine all of these systems into one single entity under TDPUD (TDPUD, 2004). The Town of Truckee Coldstream Specific Plan March 2014 Final Environmental Impact Report 4.0-33 4.0 MINOR REVISIONS TO THE EIR water system serving the Lahontan subdivision is owned by the Placer County Water Agency (PCWA) and is currently operated by the Northstar Community Services District (NCSD) under contract with PCWA. It is known as the PCWA Zone IV system. TDPUD has prepared a Water Master Plan, which serves as a planning tool to assist TDPUD to identify existing deficiencies and budgeting for corrections of such deficiencies; anticipate areas where growth is likely to occur, consistent with the general plans of the Town, Nevada County, and Placer County, and identify system improvements necessary to serve such growth; and analyze TDPUD’s current facilities fees and set future fees. Service Area The Water Master Plan divides the Town of Truckee into several planning areas. The project site is located in the Deerfield Drive Gateway Planning Area, which encompasses the area south of the Tahoe Donner subdivision, west of the downtown area, and east of Donner Lake. TDPUD provides water service to most of the Town of Truckee as well as to the nearby areas of Nevada County and Placer County outside of the Town of Truckee boundaries. TDPUD utilizes groundwater exclusively as its source of water supply. Water Sources TDPUD acquires water from the Martis Valley Groundwater Basin. This low-lying basin consists of approximately 57 square miles and is completely contained within the larger watershed of approximately 167 square miles. The Martis Valley Groundwater Basin has a total subsurface storage volume of 484,000 acre-feet and is made up of three aquifers composed of sediments and volcanic deposits nearly 1,000 feet thick (TDPUD, 2005). Infiltration from surface water and precipitation supplies the aquifer systems, which in turn feed the wetland areas. Annual groundwater recharge depends heavily on snowmelt in the late spring and early summer. The basin-wide annual recharge is estimated at 29,165 acre-feet per year (Town of Truckee, 2006). Water Supply Facilities The TDPUD currently utilizes groundwater exclusively as its source of water supply. Historically, TDPUD used a series of springs for water, but due to water quality various concerns, these springs are no longer in active service. The TDPUD holds water rights to these sources and reserves the right to utilize them in the future if necessary. TDPUD prepared a Ground Water Management Plan in 1995, which identifies the safe yield of the Martis Valley Aquifer, TDPUD’s primary source of groundwater. Given the occupancy and water use characteristics, TDPUD determined that the aquifer will provide adequate supply to meet the project’s demands through buildout (SCO et al., 2009, pg. 5.2). In January 2011, preparation began on an updated groundwater management plan and a finite element model for the Martis Valley Groundwater Basin. This project is jointly funded by NCSD, PCWA, TDPUD, and the US Army Corps of Engineers. Completion of this work is currently expected by the end of 2012. On April 6, 2011, TPTUD’s Board of Directors adopted a resolution of intent to update the Martis Valley Groundwater Management Plan. TDPUD also maintains 1,530 line valves, 870 fire hydrants, 130 air release valves, 100 blow-off valves, and 20 pressure-reducing stations (TDPUD, 2005). Coldstream Specific Plan Town of Truckee Final Environmental Impact Report March 2014 4.0-34 4.0 MINOR REVISIONS TO THE EIR The water distribution system in the Town of Truckee includes pipes ranging in size from 14-inch mains down to 2-inch mains. The entire distribution system consists of approximately 195 miles of pipe. Single-family residential uses are charged a flat rate for monthly services. Unlike single- family units, multi-family units and commercial units are billed monthly based on individual meter readings. TDPUD provides water service to nearby areas of Nevada County and Placer County outside of the Town of Truckee boundaries. The TDPUD system includes about 216 miles of pipe ranging from 2 inches to 24 inches in diameter. Approximately 90 percent of the TDPUD’s connections are equipped with a water meter. TDPUD bills these customers (including single- family residential) on a volumetric basis in accordance with AB 2572. TDPUD has also undertaken a program to install meters on the remaining properties within the next few years. Well Facilities TDPUD has several 13 potable water wells in service, including the Prosser Heights Well, Prosser Annex Well, Glenshire Drive Well, and Sanders Well. TDPUD will determine which wells would be used for the proposed project upon construction. These wells are used to supply water throughout the service area, including the project site. Pumping Facilities The water system includes a number of pumping facilities serving the various pressure zones throughout the TDPUD water supply boundaries. There are 27 25 pumping stations with a total of 66 pumps including 12 well pumps, 40 booster pumps, and 14 hydro-pneumatic system pumps. Storage Facilities There are 26 33 storage tanks in the TDPUD water system with a total capacity of ±6,2359,500,000 gallons. All of the tanks, except one, are constructed of steel, either welded or bolted. In conjunction with these storage tanks, there are a number of pumping facilities serving the various pressure zones throughout TDPUD water supply boundaries. Treatment Facilities Because TDPUD relies solely on groundwater sources of generally very high quality, extensive treatment is not required. With one exception, the only treatment process used is chlorine disinfection. All but one of the chlorination installations uses All disinfection facilities utilize liquid sodium hypochlorite solution., with one gas chlorine installation at Hirschdale. TDPUD is considering options for arsenic treatment systems in anticipation of reductions in state and federal maximum concentration levels for arsenic (SCO et al., 2009, pg. 5.2). Arsenic removal equipment is installed at the Hirschdale and Northside wells to ensure that the finished water supplied to customers is in compliance with state and federal standards. Supervisory Control and Data Acquisition (SCADA) TDPUD’s water system includes a computerized Supervisory Control and Data Acquisition (SCADA) system to aid in system operation. The SCADA system allows operators to remotely check system status, collect and store important system data, and actually operate the system from computer workstations in the TDPUD office or in the field using portable computer equipment. The system uses radio communication between water system facilities Town of Truckee Coldstream Specific Plan March 2014 Final Environmental Impact Report 4.0-35 4.0 MINOR REVISIONS TO THE EIR and the SCADA control center. Virtually all water system facilities are connected to the SCADA system including wells, pumps, and storage tanks. Operators can access information in real time such as which wells and booster pumps are in operation and the water level in each of the tanks. WATER SUPPLY DEMANDS TDPUD Service Area Water Supply Demands As part of the Water Master Plan, TDPUD predicted present and future water demands for its entire service area. For the purpose of the Master Plan, a maximum day demand of 900 gallons per day (gpd) per single-family residential unit was adopted. Equivalent dwelling units (EDUs) for both residential and commercial water uses were computed for present and buildout conditions for TDPUD. In 1997, TDPUD’s projected water system demand at buildout was 20,583 EDUs. TDPUD adopted an Urban Water Management Plan (UWMP) in November 2005 (TDPUD, 2005)2011. The UWMP provides information on the current water supply and water use, as well as demand figures for the Town of Truckee, which is used in this Draft EIR. According to the 2005 2011 UWMP, average annual water use in the Town of Truckee in 2005 2010 was 6.64 10.17 million gallons per day (mgd), with a peak of 12.61 21.88 mgd. Town per capita water use has been trending upward for 20 years. Water demand increased at an average rate of 7.2 percent per year from 1997 through 2001. The demand greatly increased in 2001 and 2002 because the Donner Lake and Glenshire water systems were acquired by TDPUD at that time. TDPUD gives the following average day water demand values utilized by the district for planning purposes: TABLE 4.12.1-1 PLANNING-LEVEL WATER DEMANDS Type Unit Demand Hotel/Lodging 234 gal/room/day Commercial/Retail 0.4 gal/SF/day Multi-Family Residential 455 gal/unit/day Single-Family Residential 505 gal/unit/day Source: Kaufman, 2009 TDPUD has a current had a 2010 requirement for source of supply of ±4,731 6,600 gallons per minute (gpm) averaged over the maximum use day. TDPUD currently has source capacity of 7,879 9,740 gpm. However, due to limitations in pumping and transmission, only 5,824 gpm are available to the water system. This supply is not limited by pumping or transmission facilities. At buildout, the source demand is estimated to be ±12,25514,100 gpm. The Water Master Plan anticipated the construction of additional sources of supply for a total capacity of 13,974 gpm at buildout (SCO et al., 2009, pg. 5.1). The following changes are made to page 4.12-8, third through seventh paragraphs, of the DEIR: Coldstream Specific Plan Town of Truckee Final Environmental Impact Report March 2014 4.0-36 4.0 MINOR REVISIONS TO THE EIR The existing TDPUD water system extends in a long radial system. Development of the project site would provide the opportunity for TDPUD to loop TDPUD’s Deerfield Drive Gateway planning area (which includes the project site) system (SCO et al., 2009, pp. 5.1–5.2). Water service to the project site would be supplied from TDPUD’s well system. A new transmission line would need to be constructed from the well to the project site. The proposed location would require off-site improvements along the northern portion of the project site. As shown in Figure 3.0-17, connections to the existing 12-inch water lines occur in the northwestern portion of the project site, and a realignment connecting to the existing 8- inch water lines occurs along the northern portion of the project site. North Donner Pump Station Number 1a and a water line upgrade from the Donner Lake system would be located along the northwestern portion of the project site. Finally, the Deerfield Pump Station, which lies on the northeastern side of the project site, is planned to be replaced upon project implementation (SCO et al., 2009, p. 5.4). Off-site improvements would occur within the existing roadways (Donner Pass Road, Coldstream Road, Deerfield Drive), would not result in any impacts to natural resources, and would be subject to construction mitigation measures identified in this Draft EIR. The proposed project’s water distribution system would be designed in conformance with the provisions of the TDPUD Water Master Plan. The system would also be designed to be compatible with the future regional distribution facilities as identified in the Town of Truckee General Plan for the project site. Each portion of the overall water system would be constructed and installed during each phase of development within the project site. Wells and distribution lines of 6-, 8-, 10-, and 12- inch water mains would be required. These lines would be located within the roadway right- of-way. The final configuration of wells may vary depending upon water quantity requirements of development phasing. Fire flow requirements for the proposed project would be a minimum of 1,000 1,500 gallons per minute (gpm) for residential uses and 1,500 2,500 gpm for commercial uses sustained over a two-hour period (Bena, 2009). One or more water storage tanks may be required to provide fire protection, pressure regulation, and diurnal supply (TDPUD, 2009). If these tanks are required, installation will be subject to separate environmental review. The proposed project’s water distribution system design would be required to meet TDPUD and Truckee Fire Protection District standards for fire flow. The following changes are made to page 4.12-10, first through fourth paragraphs, of the DEIR: The Truckee Sanitary District (TSD) currently operates under the Sanitary District Act of 1923. TSD is the public agency responsible for the collection and conveyance of wastewater in the Truckee Basin, an area of approximately 38 square miles. Wastewater collected by TSD is conveyed to the Tahoe-Truckee Sanitation Agency (TTSA) facilities located east of the Town of Truckee. TSD operates and maintains approximately 300 miles of gravity pipelines containing 4,5002,700 manholes, 8 miles of pressure pipeline, 139 main lift stations, and 2822 smaller lift stations. TSD is a public agency, governed by a five-member board of directors. Funding is accomplished in the following manner (SCO et al., 2009, p. 5.4): • Administrative costs are funded through tax revenues received from Nevada and Placer counties. Town of Truckee Coldstream Specific Plan March 2014 Final Environmental Impact Report 4.0-37 4.0 MINOR REVISIONS TO THE EIR • Operation and maintenance costs are funded through the collection of user fees, which are collected semiannually. • Capital improvement projects are funded through the collection of connection fees, which are collected at the time of connection to the sanitary sewer system. As illustrated in Figure 3.0-17, TSD presently has facilities within the project site. These facilities consist of a 12-inch line that extends from the Donner Lake area east to Lift Station 1A the North Donner Pump Station on Deerfield Drive. A 10-inch force main then continues east from the pump station along the north boundary of the project site and connects to a 12- inch gravity line near the northeast corner of the property. A separate Sub O pump station Deerfield Pump Station is located west of the end of the paved section of Deerfield Drive. From the Deerfield Pump Station, a 6-inch force main extends east and discharges directly into connects to the 12-inch gravity line near the 10-inch force main connection. The 10-inch main This 12-inch gravity line then continues east, intersects with another line north of Interstate 80, and continues along Donner Creek and West River Street, eventually crossing the Truckee River. TSD staff has indicated that there is adequate capacity in the existing wastewater collection infrastructure to serve the project site (Tresan, 2009). This statement is supported in a detailed Sewer Capacity Analysis of these facilities prepared by GW Consulting Engineers dated May 2002 (SCO et al., 2009, p. 5.4). TSD staff has advised that once improvements are installed within the project site, the Deerfield Pump Station would be abandoned and the small number of lots currently served by that pump station would tie into the Coldstream sewer system by way of a new sewer line. The new sewage lift station proposed on-site would manage sewage generated by the proposed project and pump it to the 12-inch gravity line. Future sewer improvements within the project site are anticipated to be constructed as shown in Figure 3.0-17. These improvements include two connections to existing 68-inch sewer lines in the northwestern portion, a realignment and connection to of an existing 10- inch sewer line in the northern portion, and a proposed sewer lift station in the northwestern portion of the project site, along with the proposed pump stations mentioned above. For approximately 177 feet underneath the proposed project site, the 10-inch force main is split into two parallel pipes of 8-inch and 12-inch diameters. There are five bypass ports located on the force main as it passes through the project site. The following changes are made to page 4.12-12, last paragraph, of the DEIR: Standards for construction of sanitary sewer facilities are found in the TSD Code, Ordinance 1-982008. The TSD Code outlines TSD policy, provisions and regulations, fees and charges, installation, inspection, and maintenance of sanitary sewer facilities. The following changes are made to page 4.12-24, first paragraph, of the DEIR: ELECTRIC SERVICE Electric service in the area is currently provided by the Truckee Donner Public Utility District (TDPUD), which has a diversified portfolio of electricity sources and obtains wholesale power from a number of different entities, including Utah Associated Municipal Power Systems, Northern California Power Agency, and Western Area Power Administration. receives its electricity from Idaho Power. Electricity would be supplied from TDPUD’s Truckee substation with a backup supply from the Martis Valley substation. Electric service will be supplied from the District’s Donner Lake Substation. During contingencies, backup supply can be provided Coldstream Specific Plan Town of Truckee Final Environmental Impact Report March 2014 4.0-38 4.0 MINOR REVISIONS TO THE EIR from the District’s Tahoe Donner, Truckee, or Martis Valley substations as required. TDPUD typically requires that applicants cover all costs associated with the design and installation of electrical infrastructure, including TDPUD materials and labor. Per District policy, all costs associated with the extension of electric service including design and installation costs, shall be at the expense of the applicant. These costs include District labor, materials, connection fees, and facility fees. TDPUD currently has overhead electrical transmission lines within the existing Deerfield Drive right-of-way, on the north end of the project site. There is another overhead tap line perpendicular to the Deerfield line that crosses Donner Creek and continues on to the north. TDPUD staff has indicated that the project site can be served from existing facilities. Additional electrical conductors may be required to serve the project site depending on the extent of commercial components ultimately constructed. The District’s existing electric facilities in the project area include overhead three-phase 12.47kV distribution lines along Deerfield Drive and Coldstream Road, and an overhead crossing of Interstate 80 and Donner Creek connecting to the distribution line on Deerfield Drive. These existing overhead distribution lines will be required to be placed underground through the project area due to substantial changes to the Deerfield Drive and Coldstream Road corridors as proposed by the project. This work will be required in addition to the new underground electric facilities necessary to serve the proposed commercial and residential portions of the project. All new commercial and large-scale residential development requires the installation of underground facilities (Schlosser, 2009). Per District policy, all multi-family dwellings, commercial buildings, and land parcels that are to be divided into four or more individual lots require the installation of underground electric facilities, regardless of location. Underground electric facilities include below-grade and aboveground components. Components that are located at grade or below include vaults, pull boxes, conduits, and cables. Aboveground equipment generally consists of padmount switches, cable junction enclosures, padmount transformers, and risers. The following changes are made to page 4.12-25, first and second paragraphs, of the DEIR: California Public Utilities Commission The California Public Utilities Commission (CPUC) is the state agency that regulates investor- owned utilities only. The CPUC has no jurisdiction over public utility districts such as the Truckee Donner Public Utility District. The District is governed by a five-member Board of Directors elected by the ratepayers. The Board has authority to set rates and fees for electric service. However, the District has voluntarily adopted CPUC safety standards General Order 95 and General Order 128 for overhead and underground electric line construction. regulates privately owned electric, natural gas, telecommunications, water, railroad, rail transit, and passenger transportation companies, in addition to authorizing video franchises. The CPUC grants operating authority, regulates service standards, sets rates, and monitors utility operations for safety, environmental stewardship, and public interest (CPUC, 2007, p. 10). Traditionally, general rate cases have been the major form of regulatory proceeding for the CPUC. General rate case applications may be filed every three years, and take about a year to complete. The utility bases its revenue request on its estimated operating costs and revenue needs for a particular future year. Customer rates will be based on the CPUC’s determination of how much revenue the utility reasonably requires to operate (CPUC, 2007, p. 10). Town of Truckee Coldstream Specific Plan March 2014 Final Environmental Impact Report 4.0-39 4.0 MINOR REVISIONS TO THE EIR 4.13 POPULATION, HOUSING, AND SOCIOECONOMICS The following changes are made to page 4.13-5 of the DEIR: Ownership Affordability The median price of housing in Truckee, as shown in Table 4.13-6 above, exceeds the affordability range for all income categories except above moderate-income households. To be able to afford to purchase a home at the median sales price, a household would need to have an annual income of approximately $130,000 or 200 percent of the Nevada County median family income. This indicates that there is an affordability gap for ownership housing, even for above moderate-income households. Lower- and moderate-income households may have trouble finding housing that they can afford to purchase (Town of Truckee, 2009a). The following changes are made to page 4.13-15, fifth paragraph, of the DEIR: The project site has largely been used for mining in the past and does not contain a significant number of existing residential units. There are a few is one residential units located in the northern portion of the project site along the unpaved road extending from the western terminus of Deerfield Drive. portion of Deerfield Drive, each of which is currently occupied. These units This sole unit would be demolished as part of the proposed project, resulting in the displacement of their the current occupants. However, the displacement of these units this unit is not considered substantial, and the construction of replacement housing would not be needed elsewhere. While possible off-site trails to the east would be located adjacent to existing homes, installation of the trail would not necessitate the removal of any housing. 4.14 GREENHOUSE GASES AND CLIMATE CHANGE The following changes are made to page 4.14-17, last paragraph, of the DEIR: MM 4.14.1 The project applicant shall include the following energy-efficient building measure, to be applied to site development for each structure: • Exceed California minimum energy efficiency standards (Title 24, Part 6) by 15 percent or more at the time of building permit issuance. • Comply with standards that are in effect at the time of building permit issuance or provide a 15 percent reduction from current (2011) Title 24, Part 6 standards, whichever is more stringent.
