Initial Study and Negative Declaration
: � Town of Truckee—2014-2019 Housing Element '
1 .0 INTRODUCTION
The Town of Truckee (Town) encompasses approximately 34-square miles in the eastern portion of Nevada County,
in the Lake Tahoe region of northeastem California. The Town of Truckee Housing Element(Project)comprises one
of the seven State of California mandated General Plan Elements. The Housing Element provides for the
identification and analysis of existing and projected housing needs, and articulates the Town's o�cial policies for the
preservation, conservation, improvement. and production of housing.
Following preliminary review of the proposed Project. the Town of Truckee has determined that the Project is subject
to the guidelines and regulations of the California Environmental Quality Act (CEQA). This Initial Study addresses
the direct, indirect, and cumulative environmental effects associated with lhe Project, as proposed,
1.1 STATUTORY AUTHORITY AND REQUIREMENTS
In accordance with CEQA (Public Resources Code Sections 21000-21177) and pursuant to Section 15063 (Initial
Study)of Title 14 of the California Code of Regulations(CCR), the Town of Truckee, acting in the capacity of the lead
agency, is required to undertake the preparation of an Initial Study to determine whether the Project would have a
significant environmental impact. If, as a result of the Initial Study, the lead agency finds that there is evidence that
any aspect of the Project may cause a significant environmental effect, the lead agency shall further find that an
Environmental Impact Report (EIR) is warranted to analyze Project-related and cumulative environmental impacts.
Alternatively, if the lead agency finds that there is no evidence that the Project, either as proposed or as modified to ,
include the mitigation measures identified in the Initial Study, may cause a significant effect on the environment, the
lead agency shall find that the Project would not have a significant effect on the environment and shali prepare a
negative deGaration or mitigated negative declaration for the Project. Such determination can be made only if"there
is no substantial evidence, in light of the whole record before the lead agency"that such an effect may occur(Section
21080(c), Public Resources Code).
The environmental documentation, which is ultimately approved andlor certified by the Town in accordance with
CEQA, is intended as an informational document undertaken to provide an environmental basis of subsequent
discretionary actions upon the ProjecL The resulting documentation is not, however, a policy document, and its
approval andlor certification neither presupposes nor mandates any actions on the part of those agencies from which
permits and other discretionary approvals would be required.
The environmental tlocumentation and supporting analysis are subject to a public review period. During this review,
comments on the document relative to environmental issues should be addressed to the Town. Following review of
any comments received, the Town will consider these comments as a part of the ProjecYs environmental review and
indude them with the Initial Study documentation for consideration by the Town.
1.2 PURPOSE OF INITIAL STUDY
The purpose of the Initial Study is ta (1) identify environmental impacts; (2) provide the lead agency with information
to use as the basis for deciding whether to prepare an EIR or a negative declaration; (3)enable an applicant or lead
agency to modify a project mitigating adverse impacts before an EIR is required to be prepared; (4) facilitate
environmental assessment early in the design of the projeck (5) document the factual basis of the finding in a
negative declaration that a project would not have a significant environmental effect; (6)eliminate needless EIRs; (7) ,
determine whether a previously prepared EIR could be used for the project; and (8) assist in the preparation of an
EIR, if required, by focusing the EIR on the effects determined to be significant identifying the effects determined not

disclosure requirements for inclusion in an Initial Study:
(1) A description of[he project including the location o(the projecC
(2) An identification o(the environmen[al setting;
(3) An iden[ification of environmental effects by use of a checklis[, matrix, or other me[hod, provided [ha[
entries on a checklist or other (orm are briefly explained ro indicate [ha[ there is some evidence [o
support the entries. . .;
(4) A discussion of ways ro mi[igate significant ef(ects iden[ified, if any;
(5) An examination of whe[her the projec[is compa[ible with existing zoning, plans, and other applicable
land use con[rols;and

• Town of Truckee 2025 General Plan November 16, 2006. The Town of Truckee 2025 General Plan
(General Plan) is intended to guide development and conservation in Truckee through 2025, by establishing
a policy basis for decision making, particularly for land use antl development in the Town. The General Plan
identifies the ultimate amount of development that could theoretically occur under the land use designations
established in the Plan, the guiding principles, goals, policies, and actions of the Plan are based around
projections of growth over the next two decades, which, in the case of residential development, was
expected to be less than the ultimate buildout amounL General Plan Table 1-2, 2025 General Plan Buildout
Projections: Residen[ial Units, summarizes the General Plan's residential and nomresidential development
for the year 2025. As indicated in Table 1-2, growth projections for the 20-year General Plan estimated that
there would be approximately 19,901 housing units and a population of 2$263 persons at General Plan
buildout, which is estimated to occur in 2030. The General Plan includes an Introduction, as well as eight
separate "elements° that establish Guiding Principles, Goals, Poiicies, and Actions for each given subject.
Six of these elements (Land Use, Circulation, Housing, Conservation/Open Space, Noise, and Safety
Elements)cover each of the seven topics required by Govemment Code Section 65302, while the remaining
two elements (Community Character and Economic Development Elements) have been prepared by the
Town to meet local needs and concems. The General Plan was utilized throughout this Initial Study as a
fundamental planning document governing the proposed Housing Element, Background and policy
' information from the General Plan are cited in several sections of this Initial Study.

• Town of Truckee 2025 General Plan Draft Environmental Impact Report (DEIRI Mav 2006. The 2025
General Plan EIR (GPEII� is intended to provide an assessment of the potential environmental
consequences of adoption and implementation of the proposed 2025 Town of Truckee General Plan
Update. The assessment was designed to inform Town of Truckee decision-makers, other responsible
agencies, and the public-at-large of the nature of the General Plan Update (GPU) and its impact on the
environment More specifically, the Program EIR evaluates the potential individual and cumulative
environmental effects associated with implementation of the policies and programs of the General Plan.
DirecUprimary effects of the General Plan, as well as any potential indirecUsecondary impacts, which may
occur through the horizon year (2025) were evaluated. The GPEIR provides recommendations (i.e„
mitigation measures)to avoid or minimize potentially significant effects. and describes the consequences of
unavoidable emironmental impacts. Alternative General Plan options were evaluated.
The GPEIR concluded General Plan implementation would increase the Town's housing inventory from
approximately 1Q823 units (in 2004) to a total of 20,082 units at buildout (2030), which would be an
increase of approximately 9,259 units.� z Another 627 units would be located within the Sphere of Influence
(S01) at General Plan buildout. The 2025 General Plan proposed to accommodate projected grow�h by
allocating land for new residential development. An estimated 46 percent of all housing units at buildout are
expected to be seasonal or vacation homes.3 Similarly, the GPEIR concluded General Plan implementation
would increase the Town's population from approximately 15,311 persons(in 2005)to approximately 28,520
persons at buildout (2030), an increase of approximately 13,209 persons or 86.3 percent. Additionally, the
GPEIR concluded that significant and unavoidable impacts would occur regarding the folfowing issue areas:
- Aesthetics and Visual Quality: '
- Air Quality;
- Biological Resources:
- Noise:
- Population, Employment, and Housing; and
- Traffic and Circulation.
The GPEIR was utilized throughout this initiai Study as a fundamental planning document governing the
proposed Project. Background information and condusions from the GPEIR are cited in several sections of
this Initial Study. The GPEIR was also used in the Initial Study for the 2007-2014 Housing Element update.
• Town of Truckee Municipal Code. as amended, The Truckee Municipal Code consists of all ordinances
adopted by the Town Council, which are of a general and permanent nature. Title 18. Development Code,
of the Truckee Municipal Code. carries out the policies of the Truckee General Plan by classifying and

2.0 PROJECT DESCRIPTION
2.1 PROJECT LOCATION
The Town of Truckee (Town) is located in the Lake Tahoe region of northeastem California, in the eastern portion of
Nevada County. The Town is situated approximately 12 miles north of Lake Tahoe, 30 miles west of Reno, Nevada,
and 100 miles northeasl of Sacramento: refer to Exhibit 2-1. Reoional Contexc The Town lies just east of the Sierra
Nevada's crest at Donner Pass, within the Truckee River Valley and surrounding upland areas.
2.2 ENVIRONMENTAL SETTING
Exhibit 2-2, Proiec( Area. illustrates the precise Town of Truckee corporate limits (Project area) The Town is
situated in the Truckee River Valley and is surrounded by prominent peaks and ridgelines of the Sierra Nevada
mountain range. The Town's elevations range from 5,540 feet in the vicinity of Boca to nearly 7,500 feet in Tahoe
Donner. The abundance of undeveloped open space areas and natural features (i.e., Donner Lake in the Town's
westem portion, and the Truckee River, which drains from Lake Tahoe to the south to Pyramid Lake in Nevada)
serve as key elements contributing to the Town's physical character. Additional significant creeks and streams that
flow through Truckee are Trout Creek, Alder Creek, Cold Creek, Donner Creek, and Martis Creek. Significant
amounts of open space exist in the Town, encompassing two general areas: the relatively flat allwial areas in the
eastem portion of the Town, and the areas of steeper slopes and more varied terrain around Donner Lake, in the
' Tahoe DonnerArea, and north of Interstate 80.
Truckee's Town limits encompass an area of approximately 34 square miles. which includes the historic downtown
core, a newer regional retail and public service oriented area in the Gateway area along Donner Pass Road, and a
series of dispersed residential neighborhoods (i.e., Tahoe Donner, Donner Lake, Glenshire-Devonshire, Prosser
Lakeview, Olympic Heights. Sierra Meadows, and Ponderosa Palisades). Interstate 80 and the Union Pacific
Railroad, both major iranscontinental transportation routes, and the Truckee River, each traverse the Town in an east
to west orientation. The Nevada County line forms Truckee's southern boundary. The Town is bordered to the north
by public open space lands in unincorporated Nevada County, while incorporated areas in Placer County of very low
density and rural residentiai development, interspersed with undeveloped open space are located to the east and
west.
POPULATION
The Town of Truckee is one of three incorporated cities in Nevada County. The County has experienced growth in
population over the first decade of the 2000s and a decrease in population since. According to the Department of

Housing Inventory
In 201Q the U.S. Census reporled 12.803 housing units in Truckee, which was 221 percent of all units in Nevada
County; refer to Table 2-2, Housing Inventory 2000-2014. In 2010. Truckee's housing stock represented 24.3
percent of the Countys total housing stock. The U.S. Census estimated 12,803 housing units in Truckee in 2010, a
30.8 percent increase since 2000. In 2014, Truckee housing stock represented 24 4 percent of ihe County's total
housing stock. The Department of Finance estimated 12,936 housing units in Truckee in 2014. a 1.04 percenf
increase since 2010.

Vacancy Rates
Vacancy rates are a measure of the general availability of housing in a community and indicate how well the types of
available units meet the housing demand market. A low vacancy rate suggests that households may have difficulty
finding housing within their price range; a high vacancy rate indicates either the existence of a high number of units
undesired for occupancy, or an oversupply of units. In general, a vacancy rate of 5.0 percent indicates a housing
market where supply sufficiently satisfies demand, which is considered normal enough to minimize price pressures i
on rents. In 2010, Truckee's vacancy rate was 50.5 percent; refer to Table 2-6, Occupancy S[atus bv 7enure 2010
The Department of Finance estimates that the vacancy rate in Truckee has not changed since 2010 This number is
high because it reflects the large number of units that are used for seasonal or occasional use. The number of units
that are used for seasonal or occasional use (5,989) are subtracted from the number of vacant housing units ro
' determine a more accurate assessment of Truckee's vacancy rate. By this measure, 3.7 percent of Truckee's
housing units were vacant in 2010.

Age of Housing Stock
The age of housing is often an indicator of housing conditions. In generaL housing that is 30 years or older may
need minor repairs due to the expected lifespan of building materials Housing over 50 years old is more likely to
need major repairs. Approximately 30.8 percent (3.970 units) of Truckee's housing units were constructed prior to
1980 and 5.9 percent (764 units) were constructed prior to 1960 These housing units represent housing stock at-
risk of deterioration if the units are not rehabilitated Most of fhese units are located near ponner Lake and in the
Downtown area,
Housing Conditions ,
Housing is considered substandard when conditions are found to be below the minimum standard of living defined in
the Califomia Health and Safety Code. Households living in substandard conditions are considered as being in need
of housing assistance, even if they are not seeking altemative housing arrangement, due to threat of health and
safety.
In addition to structural deficiencies and standards, lack of infrastructure and utilities often serve as indicators for
substandard conditions. According to the 2010 U.S Census, 91 occupied units in Truckee lacked complete plumbing
facilities. A total of 137 occupied units lacked complete kitchen facilities These units are likely cabins used for
seasonaluse,
Regional Housing Needs Assessment
A local jurisdiction's "fair share" of regional housing need is the number of additional housing units neetled to
accommodate the forecasted grovrth in the number of households. to replace expected demolitions and conversion of
housing units to non-housing uses, and to achieve a future vacancy rate that allows for healthy functioning of the
housing markeL
The fair share is allocated into the four household income categories used in State and Federal programs: very low-.
low-. moderate- and above moderate-income. The Town must also plan for the growth needs of extremely low-
income households. The extremely low-income need is assumed to be 50 percent of the very low-income allocation.
The allocations are further adjusted to avoid an over-conceniration of lower income households in any one
, jurisdiction.
The allocation of housing needs begins with the Department of Finance projection of the rolal sfatewide housing '
demand which is fhen apportioned by the Sfate Departmenf of Housing and Communiry Development(HCD) to each

future housing needs.
The Sierra Planning Organization (SPO) is responsible for allocating housing in the region including the Town of
Truckee. The SPO prepared a Regionai Housing Neetls Assessment (RHNA) quantifying the existing and projected
growth needs for Truckee in the previous 4�" cycle planning period (2007-2014) and for the new 51b cycle planning

2.3 PROJECT CHARACTERISTICS
The Housing Element comprises one of the seven General Plan Elements mandated by the State of California, as
expressed in Sections 65580 to 65589.8 of the California Government Code. Califomia State Law requires that the
Housing Element consist of "identification and analysis of existing and projected housing needs and a statement of
goals, policies, quantified objectives, and scheduled programs for the preservation, improvement, and development
' of housing."
As required by State Housing Law, the Town of Truckee must plan for its share of the region's new housing needs in
five state-defined income categories by identifying an atlequate supply of land zoned at appropriate densities to
accommodate needs in each income category. The RHNA goals do not explicitly require the Town to construct the
identified housing need, but rather seek to ensure the Town has, or plans to add policies, programs, and regulations
that will accommodate new housing growth.
To address the Town's needs for very low- and low-income housing, Truckee must demonstrate that it has an
atlequate supply of land for higher density housing, Although zoning land for higher density development does not
guarantee the construction of housing that is affordable to low and moderate income families, without such higher
density zoning,the opportunity to provide housing for lower income households is limited.
The Town of Truckee 2014-2019 Housing Element identifies and analyzes existing and projected housing needs, and
articulates the Town's official policies for the preservation, conservation, improvement, and production of housing
within the Town. The Housing Element has been prepared in compliance with State Housing Element law. It
examines the Town s housing needs, as they exist today, and projects future housing needs. It sets forth statements
of community goals, objectives, and policies concerning those needs, and it includes a Housing Policy Program that
responds to current and future needs within the limitations posed by available resources. The Housing Policy
Program details a series of actions to achieve its goals and objectives. Upon adoption by the Truckee Town Council,
the updated Housing Element would serve as a comprehensive statement of the Town's housing policy and provide a
specific program of actions for implementation.
HOUSING POLICY PROGRAM
, Section C, Policy Program, of the Housing Element outlines the Town's Policy Program for the 2014-2019 Planning
Period. The Policy Program identifies the specific policy actions necessary to address present and future housing
needs, meet the specific requirements of State law, and consider the input by residents and stakeholders The

Section 65583(c)),
CAPACITY TO MEET REGIONAL SHARE GOALS
In order to meet the 302 unit shortfall from the 4�"cycle Housing Element, the housing element includes Program H-
1.1.1, which directs the Town to rezone six sites and include an overlay zone on an additional site by June 30, 2015.
The Town will rezone the six sites to a newly created Zoning District RM-18 that allows a minimum of 16 units per
acre and allows up to 18 units per acre.The Town is also proposing a new multi-family zoning overlay district)that
will allow multi-family housing at 16 units per acre by right on selected sites(OV-1 listed below).
Table 2-12, Candida[e Remne and Overlay Si[es lists the estimated units available for development at each site.
With the implementation of Program H-1.1.1,the Town will cover its shortfall and will meet its 2007-2014 RHNA
obligations. If all the proposed sites were rezoned, there would be a total of 543 estimated units for lower income
households. This is a surplus of 241 units over the 302 units required to fulfill the 2007-2014 RHNA requirements.

To enable the Town to meet RHNA construction goals, the Town has evaluated its capacity to meet future needs
based on existing development capacities. Title 18 of the Truckee Municipal Code, Zoning, identifies six Residential
Zoning Districts (i.e., Rural Residential (RR), Single Family Residential (RS), Multi-Family Residential (RM),
Downtown Single Family Residential (DRS), Downtown Medium Density Residential (DRM), and Downtown High
Density Residential (DRH). Additionally, there are two Master Plan areas, Railyard Master Plan and Hilltop Master
Plan, and two Specific Plan areas (Coldstream PC-1 and Joerger Ranch PC-3 Specific Plans) that are anticipated ro
be adopted andlor implemented in the next planning period. The availability of land suitetl to accommodate the
various income levels is based upon the allowable density within these land use zones
Sites Currentiv Available to Accommodate Lower and Moderate Income Housinq Units, Table HC-10 of the Housing
Element, summarizes the sites in the Town of Truckee available to accommodate a portion of the Town's lower and
' moderate income RHNA need utilizing current zoning and development standards. Appendix HC-1 describes the
realistic capacity of each available site and considers all applicable land use controls, site improvement
requirements,existing uses, and infrastructure and environmental constraints.
These sites have the capacity for ihe development of 189 dwelling units(98 affordable to low-income households and
91 affordabie to moderate-income households). The Town's General Plan includes a policy that requires new
residential projects to develop at a minimum density equal to 90 percent of the maximum allowetl density in the
Zoning District. Through implementation of this policy, the Arnold DMU, Arnold DRH, and Winter Creek Multi-Family
sites can accommodate a portion of the Town's regional housing need for lower-income units consistent with the
criteria established by AB 2348. The Aspen Meadows, Jibboom Street DRM, and Tahoe Forest Hospital Gateway
sites allow densities appropriate to accommodate moderate-income units.
Candidate Sites for Rezoninq. After accounting for units constructed, under construction or approved, and sites
currently available to accommodate the lower- and moderate-income needs, the Town has a remaining RHNA need
of 181 units affordable to lower-income households.
Pursuant to AB 234$ jurisdictions with a remaining RHNA need must commit to a rezoning program to provide
adequate sites to meet its remaining need. To accommodate its remaining lower-income RHNA need, the Town
would need to rezone a minimum of 5.6 acres to permit by-right residential development at a minimum net density of
15 dwelling units per acre. Of the rezoned land, a minimum of 2.7 acres must permit exclusively by-right residential
uses to accommodate at least 50 percent of the Town's very-low and low-income growth need. As required by law,
each rezoned site would allow a minimum of 16 units,
The Town of Truckee has identified candidate sites for rezoning to meet the remaining RHNA need. Table HC-11 of
, the Housing Element summarizes these sites. These sites have the capacity for development of 1,102 dwelling units
' (573 affordable to lower-income households and 320 units affordable to moderate-income households). Based on
the proposed zoning and density standards, 209 Coldstream sites can accommodate units affordable to above
moderate income households, and 86 Coldstream sites and 102 Joerger sites can accommodate units affordable to

moderate income households. The remaining sites can accommodate lower-income units consistent with the criteria
established by AB 2348.Appendix HG2 of the Housing Element describes the proposed zoning and realistic capacity
of each candidate site and considers all applicable land use controls and site improvement requirements, existing
uses, infrastructure, and environmental constraints.
Sites Summarv. Table HC-12 of the Housing Element summarizes the construction achievements, units under
construction, approved units, and avaiiable sites for residential use that fulfill a portion of Truckee's RHNA need.
Table HG12 also indicates the capacity within candidate sites for rezoning. As indicated in Table HC-12, the Town
has the capacity to exceed its RHNA.
It is noted the candidate sites identified above are currently designated for commercial or high density residential
uses in the General Plan, thus. General Plan amendments would not be required. Moreover, densities and
intensities for each of the General Plan's land use designations reflect a Town-wide average.° In actuality, however,
the zoning of an individual parcel may be at a higher density provided that all parcels in the land use designation
Town-wide would have an average density consistent with that specified for that land use category. Therefore, the
rezonings would not be inconsistent with the General Plan or result in increased cumulative environmental impacts
not addressed in the GPEIR. Finally, without specifc housing project details, it is not possible to precisely determine
the environmental impacts resulting from the future residential development anticipated by the Housing Element. All
future residential development, including the future rezoning of candidate sites. would undergo separate
environmental review pursuant to CEQA Guidelines.
2.4 PROJECT OBJECTIVES/GOALS '

answer is explained where it is based on project-specific facrors, as well as general standards,
• Less Than Significant Impact: The project would have the potential for impacting the environment,
although this impact would be below established significance thresholds.
. Impact Adequately Analyzed in Earlier Analysis (i.e., GPEIR): Earlier analyses have been used where,
pursuant to ihe tiering, program EIR, or other CEQA process, an effect has been adequateiy analyzed in an
earlier EIR or negative declaration.
• Negative Declaration: Less Than Significant With Mitigation Incorpora[ed: The project would have the
potential to generate impacts that may be considered a significant effect on the environment, although the
incorporation of mitigation measures has reduced an effect from "Potentially Significant ImpacY' to a "Less
Than Significant Impact." Mitigation measures have been identified and an explanation provided on how
they reduce the effect to a less than significant level.
• Potentially Significant Impacr "Potentially Significant ImpacP' is appropriate if there is substantial
evidence that an effect may be significant If there are one or more "Potentially Signifcant Impacf' entries I

4.7.a. Have a substantial adverse effect on a scenic vista?
Impact Adequately Analyzed in GPEIR. GPEIR Figure 4.1-1, Scenic Resources, illustrates the locations of the
Town's, scenic corridors, scenic vistas, and prominent slope, ridge lines, bluff lines, and hillsides. As indicated in
Figure 4.1-1, scenic resources exist throughout the Town. The Town's housing needs would be accommodated
within vacant land permitted for residential use and redevelopment, which could potentially have a substantial
adverse effect on a scenic vista.
The GPEIR anticipated approximately 20,082 units within the Town, including redevelopment in existing community
areas and new development on currently vacant lands. The GPEIR concluded the 2025 General Plan contains
numerous goals, policies, and actions intended to preserve scenic views and vistas, including those of high mountain
ridges and peaks into the future, which would result in a less than significant impact to scenic vistas under the
proposed General Plan.s The proposed Housing Element was considered in the GPEIR analysis, since additional
residential development was assumed. Therefore, Project implementation would be consistent with the analysis
presented in the GPEIR, and would result in no greater impacts to scenic vistas than previously identified. Future
residential development would be subject to compliance with the General P�an Policies that would work in
conjunction with existing Town design and development standards to ensure that new residential development
complements the Town's and adjacent areas' existing aesthetic environment and does not impair scenic vistas.
Moreover, future residential development would be subject to compliance with Truckee Development Chapters 18.36
(Hillside Development StandardsJ and 18.46 (Open SpacelCluster Requiremen[s), which establishes regulations for
development within hillside and open space areas in order to preserve and protect the views to and from hillside and
open space areas, and preserve significant features of the natural topography (I e, swales, canyons, knolls,

ridgelines, and rock outcrops) and the Scenic Corridor . Project implementation would result in less than significant
impacts on a scenic vista.
Mitigation Program: No further mitigation is required beyond compliance with the following General Plan Policies:
Communitv Character Element
P2.1 Protect views of hillsides. prominent slope exposures, and ridge and bluff lines through a clustering
requirement for residential development that concentrates development on the most levei and least
visible portions of hiliside sites.
P2.2 Prevent development along ridge and bluff lines that disrupts the natural skyline or silhouette of the
landform.
P2.3 Prohibit intensive and visually obtrusive development on prominent hillsides, ridges, bluffs and steep
slope areas in Truckee.
P2.7 Require electric, telecommunications and cable television facilities serving new development to be
installed underground wherever possible. Where undergrounding is impractical, above ground
antennae and telephone and high voltage transmission lines shall be located out of significant scenic
vistas.
P3.1 Regulate the visual appearance and location of development within identified buffer areas along '
Interstate 80 and Highway 89 North in order to protect the visual quality of these corridors and the
views that are available from them.
P3,2 Require that all buildings at the existing Interstate 80IHighway 89 NorthlHighway 267 interchange be
substantially screened from sight from the interchange.
P3,4 Require preservation of existing vegetation on sites along I-80 to screen existing and new development
visible from Interstate 80. Where necessary, require additional landscaping to screen buildings and
other facilities. Accommodation shall be made to permit visibility of signage for approved Highway
Commercial uses in areas where such uses are specifically permitted.
P15.1 Ensure that new riverfront development along West River Street protects the scenic and environmental
quality of the Truckee River.
P16.1 Regulate development in the Donner Lake area to avoid or mitigate the visual impacts created by
construction of large homes on small lots along the lakefront and within adjacent neighborhoods.
P162 Regulate the design character of new discretionary development along Donner Pass Road in the
Donner Lake area, to ensure compatibility with the character and scenic quality of the wooded lake
shore. its rustic cabins,and the lake waters.
Circulation Element
P61 Locate, construct and maintain new roads and roadway improvements so as to prevent adverse �
impac(s to water quality and significant biological. scenic and historic resources.

P2.1 Prohibit development within established setback areas from the Truckee River, except as otherwise
allowed in the Development Code. Outside of the Downtown Specific Plan Area, development shall be
set back a minimum of 100 feet from the edge of the Truckee River 100-year floodplain. Within the
Downtown Specific Plan Area, development shall be set back a minimum distance from the edge of the
100-year floodplain that is equivalent to one foot above the base fiood elevation. Grading, landscaping
and drainage uses within the established setback area shall also be subject to strict controls.
Improvements for public access and use may be allowed within the established setbacks.
P2.6 Regulate development and land uses along the Truckee River corridor and Donner Lake to ensure
compatibility with their scenic, recreational and habitat values.
P2.8 Prohibit development within the established setback areas from Donner Lake, except as otherwise
allowed in the Development Code, and enhance degraded areas within the Donner Lake 100-year
floodplain and setback, possibly in association with a related project approval, or as off-site mitigation
for development projects.
4.1.b. Substantially damage scenic resources, including, but no[limited to, trees, rock outcroppings,
and historic buildings within a state scenic highway?
' Impact Adequately Analyzed in GPEIR. There are no State-designated scenic highways in or through Truckee.
However, there are two General Plan designated scenic corridors: the length of I-80 where it passes through the
Town limits(excluding the south side of the highway in the Downtown area); and SR 89 Norih, between Prosser Dam
I Road and the northem Town limits; refer to GPEIR Figure 4.1-2, Corridors and Gateways. The residential
development accommodated by the Project could potentially damage scenic resources within the Town's scenic
corridors, depending upon the developments' location and proximity to the corridors.
The GPEIR anticipated residential development throughout the Town and concluded development allowed under the
2025 General Plan would result in less-than-significant adverse aesthetic and visual impacts to the Town's scenic
highway corridors.b The proposed Housing Element was considered in the GPEIR analysis, since additional
residential development was assumed. Therefore, Project implementation would be consistent with the analysis
presented in the GPEIR, and would result in no greater impacts to the Town's scenic corridors than previously
identifed. Future residential development would be subject to compliance with the General Plan Policies that would
work in conjunction with existing Town design and development standards to ensure that new residential
development complements the Town's and adjacent areas' existing aesthetic environment and does not impact
scenic corridors. Compliance with the General Plan's Policies would regulate the visual appearance and location of
development along the corridors, thereby protecting the corridors' visual quality and the views that are available from
them. Project implementation would result in less than significant impacts on scenic resources within the Town's
corridors,
Mitigation Program: No further mitigation is required beyond compliance with the following General Plan Policies:

4.1.c. Substantially degrade the existing visual character or quality of the site and its surroundings?
Impact Adequatety Anatyzed in GPEIR. The Town's visual character is comprised of its mountain environment and
dramatic alpine setting. varied topography and extensive open space areas, as well as the character of its historic
center and dispersed residential neighborhoods. The residential development accommodated by the Project could
potentially degrade the existing visual character or quality of the site and its surroundings.
The GPEIR anticipated on-going growth and redevelopment in Truckee's established community areas, and the
extension of growth on some sites and into some areas that are currently undeveloped open space The GPEIR
concluded the impact to town-wide and community area visual character would be less than significant.' The I
proposed Housing Element was considered in the GPEIR analysis. since additional residential development was i
assumed. Therefore. Project implementation would be consistent with the analysis presented in the GPEIR, and
would result in no greater impacts to the Town's visual character than previously identified. Future residential
development would be subject to compliance with General Plan Policies, which set a Town-wide framework that '
would balance open space preservation with the new development, and would ensure that new development
supports high qualiry urban design and architecture and preserves and improves the Town's visual quality. Projecl
implementation would result in less lhan significant impacts to the existing visual charactedquality of the Town and its
surroundings.
Mitiga[ion Program: No fuRher mitigation is required beyond compliance with the following General Plan Policies:
Land Use Element
P1.1 All new development shall meet important community goals for design quality, open space
preservation, and promotion of a livable sustainabie community. Development that does not fulfill these
goals shall not be allowed,
P32 Discourage future subdivision of estate type parcels (2.5 to 10 acres in size) within the Town
boundaries outside of existing rural subdivisions.

Communitv Character Element
P1.1 Utilize the mechanisms and strategies identified in the Conservation and Open Space Element of the
General Plan as a tool to actively protect open space in Truckee, including that containing or
contributing to the town's scenic mountain qualities.
P1.2 Ensure that all new development, occurring at all scales and densities, maximizes the provision of all
types of open space, including scenic open space that contributes to and enhances the town's
community character
P1.3 Cluster new development so as to preserve the maximum amount of desired types of open space. as
identifed in the Conservation and Open Space Elemen(.
P1.4 Create a wnnected network of open spaces in Truckee that is accessible to the community for outdoor
recreation and other use and enjoyment, as a key aspect of local community character.
P2.4 Ensure that new development in Truckee's lowland areas, including its forested areas and
meadowlands, and the Truckee River Valley, contributes to and enhances the scenic quality and visual
harmony of the built environment that comprises the Truckee townscape.
P2.5 Preserve the scenic qualities of the Truckee River and other natural waterways through setback
' standards, as identified in the Conservation and Open Space Element, and by ensuring that new
development respects and enhances the aesthetic qualities and natural environment of these river
corridors and waterways.
P2.6 Protect the scenic qualities of Donner Lake, including views of the Lake itself from public ways and
Donner Memoriai State Park, and views from the Lake to the shoreline and the mountain slopes and
ridges beyond.
P2.9 Encourage the planting and maintenance of roadside landscaping and the use of landscaping elements
where appropriate along major public thoroughfares.
P2.10 Encourage the preservation of trees and native vegetation, including specimen trees, in development
projects.
P5.1 Ensure that planning and development decisions are oriented towards the maintenance of Truckee's
unique character, reflecting the following considerations:
. Identification of specific types of centers, residential neighborhoods, employment districts, corridors
and gateways.
• Respect for the quality, character and conte# of existing development within these different areas
of the town.
• Ensuring that new development enhances the desired character of each of these areas.
• Discouraging new architecture that directly mimics or is derivative of the buildings of the historic
downtown.
• Encouraging the retrofit or rehabilitation of existing buildings to more closely comply with Town
' • policies, standards and guidelines for high quality architecture and design.
Consideration of the relationship of the built environment to the qualities and conte# of the
landscape and natural environment in which it is situated.

P52 Require all new development to incorporate high quality site design, architecture. and planning so as to
enhance the overall quality of the built environment in Truckee and create a visually interesting and
aesthetically pleasing town environment
P5 8 For all new development in Truckee, consider how the integration of trees and native landscaping can
contribute to the overall quality of development-specific design and the town's unique character.
P8.7 Encourage landscaping of private propeRies, and planting of street trees along the public right-of-way
so as to facilitate an overall"greening"of the corridor.
P11 J Encourage new residential developments adjacent in appropriate locations (e.g. planned community
areas) and with appropriate site conditions to include the use of neo-traditional site design and
architectural elements. These encompass elements such as a grid, or modified grid street layout,
narrower streets, street trees, detached sidewalks, and neo-traditional house designs in keeping with
Truckee architecture and design.
P11,2 Discourage architectural monotony between individual units withln a suburban subdivision or residential
development project.
P11.3 Regulate the design of new development in residential neighborhoods in the Downtown area to ensure
compatibility between the new development and the existing residential areas.
P11.5 Create a clearly defned transition or edge between the "town" and "country" in all Truckee's town '
residential neighborhoods.
P12.1 Preserve the open space and natural features that contribute to the character of rural residential
neighborhoods through the clustered development requirement and other strategies described in the
Open Space and Conservation Element.
P122 Require new rural residential development projects to incorporate materials, color schemes and
architectural styles that allow it to blend inio the landscape and rural and mountain environment and be
less visible from adjacent roadways. The use of rustic and natural material such as stone and wood,
and color palettes that reflect the natural environment should be encouraged.
P12 3 Create "soft" or feathered edges to rural residential neighborhoods that transition into adjacent
undeveloped open space areas. Soft edges provide a gradual spatial shift from the buitt to the natural
environment at the urban fringe (e.g. a home with formal landscaping close to the residence that shifts
ro a more"natural landscape" and ultimately to undeveloped areas beyond) rather than the"hard edge"
or more abrupt transition created by buildings edges or walls.
P12,4 Provide sidewalks along at least one side of major roadways in Truckee's rural residential
neighborhoods, except those of the most rural character. where sidewalks should be minimized and
pedesfrian connections enhanced instead through development of off-road trails.
P12,5 Retain an expansive open space and mountain landscape quality as the dominant feature of Truckee's
rural residential neighborhoods.
P15 1 Ensure that new nverfront development along Wesf River Street protects the scenic and environmental '
quality of the Truckee River.

Truckee and the guiding principles, goals and policies of the General Plan.
• Preserve open space that, to the greatest possible extent, occurs in large blocks and is contiguous
and connected.
. Provide the greatest possible level of public access while respecting private property rights,
sensitive habitat values, and safety concems.
. Provide maximum benefit in terms of habitat preservation.
• Enhance the overall character of Truckee as a scenic, mountain community.
P7.4 Coordinate with the California Department of Forestry in the review of all timber harvesting and
conversion plans relative to potential impacts on visual, biological and recreational resources.
4.l.d. Create a new source of substantial light or glare, which would adversely aflect day or nighttime
views in the area?
Impact Adequately Analyzed in GPEIR. The Town's housing needs would be accommodated within vacant land
permitted for residential use and redevelopment. Residential development in accordance with ihe Housing Element
would introduce new sources of light, including light from building interiors passing through windows and light from
building exteriors(i.e., street lighting, building illumination, security lighting, and landscape lighting). Depending upon
the location of the light source and its proximity to adjacent light sensitive uses, light introduction can be a nuisance,
affecting adjacent areas and diminishing the view of the clear night sky. Lighting may cause spillover impacts to
nearby sensitive receptors,
' The GPEIR concluded development implemented under the proposed General Plan could increase the amount of
light and glare. however. implementation of the policies and actions would reduce potentially signifcant impacts of
light and glare on the Truckee community to a less than significant level. The proposed Housing Element was

' Setting. The Project site is located within the Town of Truckee, which is paR of the Mountain Counties Air Basin
(MCAB) and is under the jurisdiction of the Northem Sierra Air Quality Management District (NSA�MD). Air quality
assessments estimate emissions of air pollutants associated with short-term construction and long-term operation of
a proposed project. Both the State of California and the Federal government have established health-based Ambient
Air Quality Standards (AAQS)for the following six criteria air pollutanis. carbon monoxide(CO), ozone(03); nitrogen
oxides (NOx); sulfur oxides (SOx); particulate matter up to 10 microns in diameter(PM,o) and lead (Pb). 03 (smog)
is formed by a photochemical reaction between NOx and reactive organic gases (ROGs). Thus, evalualing impacts
from NOx and ROGs assesses impacts from 03. The net increase in pollutant emissions determines the impact on
regional air quality as a result of a proposed project. The results also allow the local government to determine
whether a proposed project would deter the region from achieving the goal of reducing pollutants in accordance with
the air quality management plan (AQMP) in order to comply with Federal and State AAQS
4.3.a. Conflict with or obstruct implementation ol the applicable air quality plan? i

The Town's housing needs would be accommodated within land permitted for residential use and redevelopment.
Construction activities for residential projects woultl generate pollutant emissions from activities, including but not
limited to, site grading, operation of construction equipment, and vehicle activities. The future housing units would
generate pollutant emissions due to uses of stationary equipment, new vehic�lar lrips, off-site power, natural gas
generation,etc.
The Town collaborated with the NSAQMD to develop the Particulate Matter Air Quality Management Plan
(PMAQMP), which was adopted in 1999. The purpose of the PMAQMP was to assess the extent of particulate
' matter (PM) pollution in the Town; establish PM pollution attainment goals; identify short-term and long-term
implementing measures, and establish guidelines for monitoring the effectiveness of adopted control measures, The
PMAQMP identifes wootl smoke from residences. dust from roadways, and consVuction activities as the primary

sources of PM emissions The GPEIR stipulates that new residential development that would occur with
implementation of the Housing Element would be required to meet the Town's standards for wood burning devices
and would minimally affect PM increases. Town roadways are sanded regularly throughout the wintec and sand is
re-emitted into the air by moving vehicles, creating a substantial amount of PM. The additional vehicles associated
with residential development could increase the amount of PM emitted into the air. However, the PMAQMP has
identifed the adoption of street sanding guidelines for Iocai roads and cooperation with the Califomia Department of
Transportation as its next major goal. The General Plan requires all new deveiopment to be consistent with the
PMAQMP. including those covered under the proposed Housing Element. The General Plan and the Development
Code also conlain policies and standards regarding construction emissions.
The proposed Housing Element was considered in the GPEIR analysis, since additional residential development was
assumed. Implementation of the Housing Element is consistent with the Land Use Element, which ensures that
growth in the Town is consistent with the PMAQMP. Individual residential development proposals would be
evaluated in detail to determine their consistency with the PMAQMP. Implementation of the proposed Project would
be consistent with the analysis presented in the GPEIR. and would result in no greater impacts than previously
identified. Therefore, Project implementation would result in less than significant impacts in this regard.
Mitigation Program: No mitigation is required.

Short-Term Construction Impacts
The Town's housing needs would be accommodated within vacant land permitted for residential use and
redevelopment, Construction activities for residential proiects would generate pollutant emissions, inGuding but not
limited to site grading, operation of construction equipment, and vehicle activities. The future housing units would
generate pollutant stationary and mobile source emissions due to uses of stationary equipment, new vehicular trips,
I off-site power and naturai gas generation, etc. As the Housing Element addresses housing units as a collective
whole and not a specific development project, no emission calculations are necessary in the preparation of this
document. Notwithstanding, residential development anticipated by the Housing Element could violate air quality
standards or contribute substantially to an existing or projected air quality violation, The GPEIR concluded shoR-term
impacts from construction and grading activities would be less than significant with compliance with State and
Federal mandated regulations and the Town's Development Code requirements (which are consistent with
NSAQMD's guidelines for mitigation), and implementation of the General Plan's goals and policies,
Long-Term Operational Impacts
Long-term impacts associated with implementation of the Housing Element could further air quality violations.
Nevada County currently exceeds State standards for ground levei ozone and PM,o Implementation of the Housing
Element would result in an increase in traffic, which could result in increased levels of ozone antl particulate matter.
The General Plan includes policies addressing reduction of vehicle miles traveled (VMT) which would reduce the
amount of pollutants emitted into the air from mobile sources. The proposed Housing Element was considered in the
GPEIR analysis, since additional residential development was assumed. Therefore, implementation of the proposed
Project would be consistent with the analysis presented in the GPEIR, and would result in no greater air quality '
impacts than previously identified Individual project proposals would be subject to review under CEQA. which would

specifically evaluate potential impacis to air quality. Therefore, long-term operational impacts from implementation of
the Housing Element would be less than significant. i
Mitigation Program: No further mitigation is required beyond compliance with the following General Plan Policies.
Land Use Element
P5,1 Strongly encourage mixed use development in appropriate locations, including the Downtown, Gateway
area and Donner Lake.
P5.6 Require that ihe feasibility of residential uses, including affordable housing, be considered as part of
any new mixed use development proposal for the Downtown, and to the extent feasible, be
incorporated into final project design.
Communitv Character Element
P6.5 Promote new mixed use and infill development in the Downtown, including at the Railyard antl Hilltop
sites.
P6,12 Preserve existing housing and encourage new housing in the Downtown, including through
incorporation of housing in projects within the Mixed Use district.
' P82 Reinforce the commercial and mixed use qualities that contribute to the "town" orientation of the
Gateway corridor.
P8.8 Encourage new mixed use development in the Gateway Area, particularly projects that incorporate both
a residential and commercial component. Uses that support and provide opportunities for community
interaction should be encouraged, such as coffee houses, restaurants, and places for children and
families.
P9.1 Promote redevelopment and infill of existing auto-oriented commercial centers and corridors with
pedestrian-friendly mixed use development.
P92 Encourage all existing and new mixed use centers to create a'park once environment`that provides a
variety of uses within walking distance.
P9.3 Require new mixed use centers to provide housing of a variety of types and affordability, including
employee housing, unless determined to be incompatible.
P9 4 Enhance pedestrian connections from nearby residential areas to local shopping centers so as to
enhance the mixed use quality of Truckee's commercial centers and their surrounding residential areas;
reduce the need to drive to access daily needed goods and services; and provide safe and wnvenient
pedestrian connections.
P9,5 Require new mixed use centers to incorporate site planning and design that reflects walkability and
opportunities for indoor and outdoor social interaction, including clustered buildings, parking dispersed
' in smaller lots, as well as pedestrian scale design features.
P13,3 Create live-work opportunities,as appropriate, within employment districts.

P15.3 Encourage the reorientation of the West River Street corridor from a location for industrial uses to a
mixed use commercial and residential area. particularly at West River StreeYs east end.
Circulation Element
P9.2 Promote land use and transportation strategies that will reduce automobile trips, particularly
implementation of compact pedestrian-oriented development, mixed uses, live-work projects,
neighborhood-serving commercial and mixed use centers. and clustered and infill development.
Conservation and Open Space Element
P13,1 Require multi-family residential, commercial, industrial, subdivisions and other discretionary
development to maintain consistency with the goals, policies and control strategies of the Town's
Particulate Matter Air�uality Management Plan.
P13.2 Existing non-paved roads within new development and subdivision, and existing off-site non-paved
roads that serve new development and subdivisions shall be paved to the e�ent necessary to offset
emissions generated by the development and subdivision traffic to the degree feasible. New non-paved
roads shall not be allowed for new development and subdivisions except for single family residences,
secondary residential units and duplexes on existing lots. New paving shall take into consideration the
policies under Goal COS-11 concerning minimization of impacts to water quality and groundwater
recharge that may result from increases in paved areas. ,
Pt3.3 Require all construction projects to implement dust control measures to reduce particulate matter
emissions due to disturbance of exposed top-soils. Such measures would include watering of active
areas where disturbance occurs, covering haul loads, maintaining clean access roads, and cleaning the
wheels of construction vehicles accessing disturbed areas of the site.
P14.3 Reduce automobile dependence, thereby reducing greenhouse gas emissions, by encouraging mixed
land use pattems that locate services such as banks, child care facilities, schools, neighborhood
shopping centers and restaurants in close proximity to employment centers and residential
neighborhoods.
P14,8 Require developers of projects that would locate sensitive receptors such as residences within the
California Air Resource Board's recommended buffer of 500 feet of I-80 and the railway to prepare a
health risk assessment to determine the significance of the impact, and to incorporate project-specific
mitigations to minimize or avoid this risk.
P14.9 Require new development with the potential ro generate significant quantities of ozone precursor air
pollutants to be analyzed in accordance with guidelines provided by the NSAQMD and appropriate
mitigation be applied to the project to minimize these emissions.
P15.5 Encourage new private and public development to maximize opportunities for use of passive or natural
heating and cooling and encourage sites with solar opportunities to be designed with natural heating
and cooling principles, I

4.3.d. Expose sensitive receptors to substantial pollutant concentrations?
Less Than Significant Impact. Refer to Response 4.3.b. In adtlition, the consiruction of individual residential
projects could potentially lead to fugitive emissions and other pollutants affecting sensitive land uses. Increased
traffic volumes on Town streets could also lead to increases in traffic congestion and associated vehicle emissions,
which could impact sensitive receptors. However, as future residential development would occur throughout the
Town, substantial localized pollutant concentrations are unlikely ro be produced Thus, less than significant impacts
are anticipated in this regard. It is also important to note the conceptual nature of the anticipated residential
development associated with the Housing ElemenL Future development proposals would be anatyzed individually
for potential impacts to air quality and to determine compliance with applicable State and Federal ambient air qua�ity
standards. If necessary, mitigation would be recommended to reduce potential air quality impacts to a less than
signifcant level,
Mi[igation Program: Refer to Response 4.3.b.
' 4.3.e. Crea[e objectionable odors aKecting a substantial number of people?
Less Than Signi(icant Impact. Odors are one of the most obvious forms of air pollution to the general public.
Odors can present significant problems for both the source and the surrounding community. Although offensive
odors seldom cause physical harm, they can agitate and alarm the general public Most people determine an odor to
be offensive(objectionable) if it is sensed longer than the duration of a human breath, typically two to five seconds.
Construction activities associated with residential projects anticipated by the Housing Element may generate
objectionable odors from heavy-duty equipment exhaust or from application of paint and asphalt. All new
development would be subject to compliance with standards established for the NSAQMD for odor control. Projects
would require consistency with NSAQMD Rule 205, Nuisance, which prohibits the discharge of air contaminants or
other materials (including odors), which can cause injury, detriment, nuisance, or annoyance to any considerable
number of persons or to the public at large. Also,the General Plan includes policies which call for the minimization of
problematic odor sources, and prohibit locating sensitive uses in the vicinity of odor-generating uses.
Any impacts to adjacent land uses would likely be short-term and are considered less than signifcant.
Notwithstanding, due to the conceptual nature of the future residential development, proposals would be analyzed
indivitlually to evaluate the potential creation of objectionable odors. If necessary, mitigation would be required to
reduce potential air quality impacts to a less than significant level,

Impact Adequately Analyzed in GPEIR. The Project area and adjacent upland and mountain areas are rich in
biological resources. The General Plan identifes several special status habitats, plant species, and wildlife species
in the Truckee area. The Town's impoRant biological resources and habitat areas are illustrated on GPEIR Figure ,
4.3-1, Biological Resources and Habi[at Areas, and outlined in GPEIR Tables 4.3-1 and 4.3-2. These vegetation and
habitat areas host a wide range of flora and fauna, some of which are designated as special status species. Other
impoRant habitat that exists within the Project area is assceiated with riparian, aquatic. and wetland resources, refer
to GPEIR Figure 4.3-2. Public and Permanen[ly Pro[ected Open Space. These include the Truckee River and
supporting riparian habitat; creeks and watenvays. and open waters The residential development accommodated by
the Project could potentially have a substantial adverse impact on species/habitats identified as a candidate. ,

sensitive, or special status. Similarly, future residential development could potentially adversely impact a riparian
habitat,other sensitive natural community, or federally protected wetlands,
The GPEIR concluded development occurring under the General Plan (inclusive of residential deveiopment) could
potentialry adversely impact:
. Habitat supporting special status plant species or destroy individuai occurrences or stands of these plants;
• A number of special status animal species, if they were present within areas permitted for future
development;
. Riparian habitat where streamside development and removal of vegetation occurs in and along the banks of
the Truckee River, Donner Lake and other streams; and
• Wetlands or waters of the U.S. in local water bodies, given the proximity of these resources to future
development areas.
The General Plan goals, policies, and actions would reduce potentially significant impacts to special status plant and
animal species and riparian and wetland habitats to a less-than-significant level.e The proposed Housing Element
was considered in the GPEIR analysis, since additional residential development was assumed. Therefore, Project
implementation would be consistent with the analysis presented in the GPEIR, and woultl resu�t in no greater impacts
to the Town's biological resources than previously identified. It is noted the Housing Element would not directly
remove sensitive species, habitats, or vegetation communities, because the Housing Element does not infer direct
development righls, Notwithstanding, future residential development would be subject to compiiance with General
' Plan Policies that protect and preserve biological resources, including requiring biological resource assessments for
all development in areas where special status specieslhabitats may be present. If necessary, mitigation would be
identifed to reduce potential biological impacts to a less than significant level, Future residential development
accommodated by the Project would be subject to compliance with the regulations and guidelines set forth in the
General Plan, Truckee Municipal Code, and development review process. Future residential development would
require further review for compliance with federal, state, and local requirements, as necessary. Project
implementation would result in less than significant impacts on specieslhabitats identified as a candidate, sensitive,
or special status, riparian habitats, other sensitive natural community, or federally protected wetlands
Mitiga[ion Program: No further mitigation is required beyond compliance with the following General Plan Policies:

interference with a wildlife movement corridor. Refer also to Response 4.4.a.
Mitigation Program: No further mitigation is required beyond compliance with the General Pian Poiicies ouUined in
Response 4.4.a and as follows.
Conservation and Open Space Element
P4.1 Provide for the integrity and continuity of biological resources open space, habitat and wildlife
movement corridors and support the permanent protection and restoration of these areas, particularly
those identified as sensitive resources.
P9.4 Preserve existing open space corridors, and connections to adjacent open space areas, and integrate
publicly accessible trails and open space corridors into new development to the extent feasible,
4.4.e. Conflic[ wi[h any local policies or ordinances pro[ecting biological resources, such as a tree
preservation policy or ordinance?
' Less Than Significant Impact. The Conservation and Open Space Element includes numerous goals and policies
intended ro protect biological resources, refer to Conservation and Open Space Element Section E, Goals, Policies,
and Actions. There are no locally-established ordinances for ihe specifying the preservation of trees or habitats.
However, the Truckee Development Code includes provisions relevant to riparian habitat and wetlands. Truckee
Development Code Chapter 18.3$ Lake and RivedStream Corridor Development, specifes standards for
development adjacent to Donner Lake, the Truckee River, and other significant streams throughout the Town, in
order to provide appropriate buffer areas. Truckee Development Code Section 18.46.040, Open SpacelCluster
Requirements, specifies that wetlands are environmentally sensitive areas that should be preserved, and that
wetlands removed or destroyed as part of new development require mitigation through restoration or creation of
wetland habitat at a rate of 1.5 units of restored habitat for each unit of habitat removed or destroyed. Future
residential development would be subject to compliance with all relevant General Plan Policies and Truckee
Development Code standards intended to protect and preserve biological resources. Therefore, Project
implementation would not conflict with local policies or ordinances protecting biological resources. Project
implementation would result in less than significant impacts involving potential conflicts with local policies or
ordinances protecting biological resources.
Mi[iga[ion Program: No mitigation is required.
4.4.f. Conflic[ wi[h [he provisions of an adopted Habitat Conserva[ion Plan, Natural Community
Conservation Plan, or other approved local, regional, or state habitat conservation plan?
No Impact. The Town of Truckee does not have an adopted Habitat Conservation Plan, nor is it subject to a County
Plan. Thus, implementation of the Housing Element would not conflict with provisions of an adopted Habitat
Conservation Plan, Natural Community Conservation Plan, or other approved local, regional, or state habitat
, conservation plan.
Mitigation Program: No mitigation is required.

Se[[ing. Historic. archaeological, and paleontological resources are present within Truckee and the surrounding
area According to GPEIR Section 4.4, Cul[ural Resources. it is estimated that only between 8.0 and 20 percent of
the Town had been inventoried for cultural resources: records associated with these surveys indicate more than 100
historic, prehistoric, and historic-prehistoric sites within the Town limits. Moreover, an estimated 65 buildings were
considered individually eligible for the NRHP and contributory to the proposed downtown Historic Distnct, and 89 '
buildings/structures were considered not individually eligible for the NRHP, but still contributory to the proposed
District. The residential development accommodated by the Project could potentially cause a substantiai adverse
change in the significance of a historical, archaeologicai, or paleontological resource.
The Town of Truckee lies within the ethnographic territory of ihe Washoe Tribe of Nevada and California. In the
1850s, when non-natives began moving into their lemtory, the Washoe homeland surrounded Lake Tahoe and the i
Sierra Nevada, south from Honey Lake, through Antelope Valley and the West Fork of the Walker River; and east '
from the westem slopes to the top of the Pine Nut Mountains in the Great Basin. The traditional way of life was based
on seasonally harvested resources —fish, animals and plants —from catchments tefhered to areas associated with
specific lineages.
After initial and sporadic resistance ro Euro-Americans appropriating camping and resources areas by "gradual
encroachmenY' during the 1860s-1870s. Washoe leaders are said to have advised a strategy of accommodation and I
negotiation. They distanced themselves from the Pyramid Lake Paiute War of 1860. for instance, and sought �
assistance from federal agents for protection of their fsheries. pine nut groves. and other resources. The Washoe
tribe achieved federal recognition in 1936 after establishing a government and constitution untler authority of the
Indian Reorganization Act of 1934.
Several themes dominate historic-period events within the Project Area, including mining an dice production, which
are both directly relevant to significant archaeological remains located within the project corridor. In their quest for
gold in 1849. man Gotd Rush immigrants passed through the Truckee Basin. as they followed the Truckee Route of
the Emigrant Traii. and crossed the Sierra in the vicinity of Donner Pass. The discovery of silver in Nevada in 1859
prompted a reverse migration, with many east-bound miners heading back through the Truckee Basin from the gold
fields of the Mother Lode to the mines of the Comstock 10 '

Although mining was carried out on an exploratory basis in the Truckee Basin, no ore bodies of any economic
importance were found. There is no doubt that the focus was on hard-rock mining and silver ore; there is no mention
of placer mining in ihe primary literature. Nonetheless, it is probable that some industrious miners engaged in limited
placer mining along waterways in search of free gold washed down from the ore deposits. While several mine
exploration pits (representative of hard-rock mining during this early era) have been recorded in the hilis surrounding
Martis Valley, no placer mining features have been formally recorded in the Truckee Basin until this project. The
rudimentary technology represented by the placer workings discovered in the project area resembles shallow hand
mining andlor ground sluicing.
By the mid-1880s, the Truckee River and its tributaries had become a focus for the Sierra Nevada ice industry,
Attractetl by the steady flows of Martis Creek and its close proximity to the railroad and the existing infrastructure
in place at Martis Creek Station, the Truckee Ice Company set up operations at the mouth of the creek in 1884. The
company was acquired by Union Ice Company by 1891, and operations closetl in 1898. In 1886, a second ice
company, the Tahoe Ice Company, commenced simultaneous operations a short distance upstream. Like the
Truckee Ice Company, in 1915 they sold out at the tum of the twentieth century to a large competitor,the National Ice
Company. Operations closed a few years later due to river pollutants and competition with manufactured ice
companies.

' Impact AdequatelyAnalyzed in GPEIR. The GPEIR notes development could occur in areas containing buildings
with potential historic significance. Changes to building exteriors or demolition would have the potential to impact
historic resources. Similarly, development allowed under the General Plan would also involve construction activities
that could result in the disturbance of undiscovered archaeological or paleontological resources during grading or
other on-site excavation activities. The GPEIR concluded implementation of General Plan Policies would reduce
impacts to historic, archaeological, and paleontological resources to less than significant levels." The proposed
Housing Element was considered in the GPEIR analysis. since additional residential development was assumed.
Therefore, Project implementation would be consistent with the analysis presented in the GPEIR, and would result in
no greater impacts to the Town's cultural resources than previously identifed. Future residential development would
be subject to compliance with General Plan policies that identify, preserve, enhance, and protect cultural resources,
Such policies would require an evaluation of impacts to historic resources for projects involving substantial site
disturbance, demolition, or alteration of known historic building, as well as archaeological or paleontological
surveying, testing, research, documentation, monitoring, and safe retrieval of archaeological and cultural resources,
as part of the development review process. Moreover, future residential development would be subject to
compliance with Truckee Development Code Chapter 18.26, Hismric Preservation Design Guidelines, and Truckee
Development Code Section 18.30.040, ArchaeologicallCultural Resources. Truckee Development Code Chapter
18.26 is intended to assist property owners and project designers in understanding the Town's goals for attaining
high quality development that is sensitive to and compatible with the historic character of the Downtown area,
Truckee Devetopment Code Section 18.30.040, Archeological/Cultural Resources, specifies the following:

for human remains. Specifically, Health and Safety Code Section 7050.5 describes the requirements if any human
remains are accidentally discoveretl during excavation of a site, As required by State law, the requirements and
procedures set forth in Section 5097.98 of the Califomia Public Resources Code would be implemented, including
notification of the County Coroner, notification of the Native American Heritage Commission, and consultation with
the individual identified by the Native American Heritage Commission to be the "most likely descendant." If human
remains are found during excavation, excavation must stop in the vicinity of the find and any area that is reasonably
suspected to overly adjacent remains until the County coroner has been called out, and the remains have been
investigated and appropriate recommendations have been made for the treatment and disposition of the remains,
Following compliance with State regulations, which detail the appropriate actions necessary in the event human
remains are encountered, impacts involving potential disturbance to human remains would be less than significant.

Regional Geology. The Truckee area, situated east of the Sierra Nevada Crest, lies within the eastern portion of the
Sierra Nevada Geomorphic Province. The Sierra is a tilted fault block nearly 400 miles long. its east face is a high,
rugged multiple scarp, contrasting with the gentle westem slope, The project area lies within the Sierra Nevada
Ecological Section and the Tahoe-Truckee Ecological Subsection, Cenozoic volcanic rocks predominate in this
subsection. There are some Mesozoic granitic rocks, Jurassic marine sedimentary rocks, and Jurassic and older
metavolcanic rocks. The Cenozoic volcanic rocks are mostly Pliocene andesite, basalt and pyroclastic rocks and
Pleistocene basalt'�.
Regional Seismicity. Geologic hazards present within the Truckee area are primarily associated with seismic activity,
although this risk is relatively low compared to other regions of California. Faults located near Truckee include: the
Polaris Fault, which lies approximately 5 miles east of the Project site near the MaRis Creek Dam: the Mohawk Valley
Fault, the southem section of which lies approximately 20 miles northwest of Truckee; and the Dog Valley Fault. which ,

extends from Dog Valley (approximately 20 miles northeast of Truckee) southwest to near ponner Lake. Several
small trace faults are also located within the Town limits. None of these faults are designated as Alquist-Priolo Special
Study Zones.Active fault zones at the eastem base of the Sierra Nevada have a history of producing moderate to great
earthquakes. The surface geology of the project has been mappetl by George J. Saucedo (2005�. The mapping
indicates there is a fault running east and west along the south side of the Truckee River and anotherfault running noRh
and south at the base of the talus slope just east of Martis Creek. According to this map, these faults' locations are
inferred.
Liquefaction Potential. Liquefaction is a type of ground failure most likely to occur in water-saturated silts, sands.
and gravels, having low to medium density. When a soil of this type is subjected to vibration, it tends to compact and
decrease in volume If the groundwater is unable to drain during the vibration, the tendency of the soil to decrease in
volume results in an increase in pore-water pressure.When the pore-water pressure builds up to the point where it is
equal to the over-burden pressure (effective weight of overlying soiq, the effective stress becomes zero. In this
condition, the soil loses its shear strength and assumes the properties of a heavy liquid.
There is a lack of published historic evidence of liquefaction in the area. However, strong ground shaking from
earthquakes should be anticipated in the Project Area. which could result in differential settlement due to soil
compression or liquefaction.
Subsidence. Subsidence is the gradual settling or sinking of the earth's surface with little or no honzontal motion.
Subsidence is caused by groundwater withdrawal, gas withdrawal, hydrocompaction or peat oxidation.
' Erosion. Erosion is a natural geological process by which landforms are worn down or reshaped by wind and water and
the eroded material is deposited elsewhere.The highest potential for erosion to occur is a result of construction activity
, where soils may be exposed for some length of time.
RegulatorySetting
State Regulations
Alquist-Priolo Geologic Hazards Zone Ac[. The Alquist-Priolo EaRhquake Fault Zoning Act (formerly the Alquist-
Priolo Special Studies Zone Act), signed into law December 1972, requires the delineation of zones along active faults
in Cal'rfomia, The purpose of the Alquist-Pnolo Act is to regulate development on or near active fauli iraces to reduce
the hazard of fault rupture and to prohibit the location of most structures for human occupancy across these traces.
Cities and counties must regulate certain development projects within the zones, which includes withholding permits
until geologic invesligations demonstrate that development sites are not threatened by future surface displacement13,
Surfacefault rupture is not necessarily resiricted to the area within an Alquist-Priolo Zone.
Seismic Hazards Mapping Act. The Seismic Hazards Mapping Act was developed to protect the public from the effects
of strong ground- shaking, liquefaction, landslides, or other ground failure, and from other hazards caused by
earthquakes. This act requires the State Geologist to delineate various seismic hazard zones and requires cities,
counties, and other local permitting agencies to regulate certain development projects within these zones. Before a
development permit is granted for a site within a seismic hazard zone. a geotechnical investigation of the sile
has to be conducted and appropriate mitigation measures incorporated into the project design.

could suffer damage in the event of an earthquake and related soil failure,
� The residential development accommodated by the Project could expose people or structures to adverse effects
involving seismic hazards, including strong seismic ground shaking, seismio-related ground failure (i.e . liquefaction),
and landslides. The intensity of ground shaking would depend upon the magnitude of the earthquake, distance to the
epicenter, and the geology of the area between the epicenter and the Town. The possibility of moderate to high
ground acceleration or shaking in the Town may be considered as approximately similar to the Southem California
region. as a whole. Refer to Response 4.6.c below for a discussion regarding landslide hazards.

Impact Adequately Analyzed in GPEIR. According to fhe GPEIR. much of the soil underlying the Town consists of
glacial tilL moraines and outwash. which can be described as siltylsandy gravels or gravellylsilty sands contain large
quantities of sediments. Soil depths typicalty range from 20 to 60 inches. Clearing and grading for construction
associated with future residential developments could result in short-term soil erosion by wind and water. and bss of
topsoiL The potential for soii erosion in any location would be largely determined by the soil type and its susceptibility
to erosion, slope, and degree of exposure to weather, especially wind and rain. Erosion of soils in Truckee that could
result in a significant loss of topsoil would largely depend on the location of that development, the properties of
underlying soils, the extent of vegetative cover, and the prevailing weather pattems.
Expansiveness refers to the potential to swell and shrink with repeated cycles of wetting and drying and is a common
feature of fne-grained clayey soils. This wetting and drying causes damage due to differential settlement within
buiidings and other improvements. Since all of the soils in the Truckee area are mainly comprised of sand,they pose
a very low risk of expansion,�s Notwithstanding, depending upon the location of the development site, future
residential development accommodated by the Project could be exposed to expansive soils, creating risk to life or
property, unless proper engineering techniques are implemented,
The GPEIR concluded soil erosion and expansion are possible risks associated with weak soils that could jeopardize
the safety of the public, however, compliance with the General Plan Policies would ensure that the hazards
associated with soil conditions would be reduced to a less than signifcant level,�� The proposed Housing Element
was considered in the GPEIR anarysis, since additional residential development was assumed. Therefore, Project
implementation would be consistent with the analysis presented in the GPEIR, and would result in no greater impacts
involving soil erosion or soil expansion than previously identified. The potential hazards from soil expansion would '

Impact Adequately Analyzed in GPEIR.
Slope Stabilitv Hazards. Threats from slope stabiiily hazards such as land subsidence and landslideslground failure
exist in the Town. Land subsidence. or settlement, is a slow-to-rapid downward movement of the ground surface that
can be caused by a variety of factors. Typically, signifcant subsidence occurs only in areas underlain by soft soils or
in areas susceptible to liquefaction. Because the sedimentary soils underlying the Town of Truckee are not
susceptible to liquefaction,the risk of land subsidence is considered to be low.
Landslides and ground failure are triggered by certain natural causes such as earthquakes, weak materials, stream
and coastal erosion, and heavy rainfall. These causes of ground failure, which normally produce landslides and
differential settlement, are augmented during earthquakes by strong ground motion. Areas along the Truckee River.
' the ridges and hilisides north and west of Downtown; the ridges north of Gateway and north and west of Donner
Lake; and areas around Alder Hill contain steep slopes of thirty percent or greater. These steep slope areas.
particularly where they occur in conjunction with weak soils, may present a significant landslide or ground failure.

consideration of the location of new residential development in relation to steep slopes and areas of unstable soils
and that soils reporls be completed for new development in areas where geologic risks are known to exist and that
these reports include recommendations for appropriate engineering and other measures to address identified risks.
Less than significant impacts would occur involving geologic units or soils that are unstable, or that would become
unstable as a result of the project
Avalanche Hazards. Figure 4,6-2, Avalanche Hazard Areas, maps the three avalanche hazard areas that exist in
Truckee, the area at the west end of Donner Lake:the area south of the lake just west of the Donner Memorial State
Park; and a smaller area at the southeast edge of Tahoe Donner. The degree of poiential hazard from snow '
avalanche would be related to a number of localized conditions, including steepness of slope, exposure, snow pack
composition, wind, temperature, rate of snowfail. and other interacting factors. Future residential development
accommodated by the Project could be located in an avalanche hazard area.
The GPEIR concluded that an avalanche event could result in signifcant impacts to public health and safety, given
that avalanche hazard areas are immediately adjacent to areas identified for residential uses in the General Plan.
However. compliance with the General Plan Policies would ensure that avalanche hazards would be reduced to a
less than significant IeveL19 The proposed Housing Element was considered in the GPEIR analysis, since additional
residential development was assumed. Therefore, Project implementation would be consistent with the analysis
presented in the GPEIR, and would result in no greater impacts involving avalanche hazards than previously
identifed. Future residential development would be subject to compliance with General Plan Policies intended to
reduce risks from avalanches. Less than significant impacts would occur involving avalanche hazards.
Mitigation Program: No further mitigation is required beyond compliance with the following General Plan Policies.

Setting. California is a substantial contributor of global greenhouse gases, emitting over 400 million tons of COZ a
year. Climate studies indicate that California is likely to see an increase of three to four degrees Fahrenheit over the
next century. Methane is also an important greenhouse gas that potentially contributes to global dimate change.
Greenhouse gases are global in their effect which is to increase the earth's ability to absorb heat in the atmosphere.
As primary greenhouse gases have a long lifetime in the atmosphere. accumulate over time, and are generally well-
mixed,their impact on the atmosphere is mostly independent of the point of emission.
The impact of anthropogenic activities on global climate change is apparent in the observational record. Air trapped
by ice has been extracted from core samples taken from polar ice sheets to determine the global atmospheric
variation of COz, methane. and nitrous oxide from before the start of the industrialization (approximateiy 1750), to '
over 650.000 years ago. For that period, it was found that COz concentralions ranged from 180 parts per million
(ppm)to 300 ppm. For the period from approximately 1750 to the present,global CO2 concentrations increased from
a pre-industrialization period concentration of 280 ppm to 379 ppm in 2005. with the 2005 value far exceeding the
upper end of the pre-industrial period range.
The Intergovernmental Panel on Climate Change (IPCC) constructed several emission trajectories of greenhouse
gases needed to stabilize global temperatures and climate change impacts. It concluded that a stabilization of
greenhouse gases at 400 to 450 ppm carbon dioxide-equivalent concentration is required to keep mean global
warming below 2°C. which in turn is assumed to be necessary to avoid dangerous climate change.
Requlations and Siqnificance Criteria
California Governor Arnold Schwarzenegger issued Executive Order S-3-05 in June 2005. which established the
following greenhouse gas emission reduction targets,
• 2010: Reduce greenhouse gas emissions to 2000 levels
• 2020: Reduce greenhouse gas emissions to 1990 levels
• 2050: Reduce greenhouse gas emissions to 80 percent below 1990 levels
AB-32 requires that the California Air Resources Board (CARB) determine what the statewide greenhouse gas
emissions level was in 1990, and approve a statewide greenhouse gas emissions limit that is equivalent to that level,
to be achieved by 2020, CARB has approved a 2020 emissions limit of 427 metric tons of COz equivalents
(MTCO2eq).

Global Climate Change Gasses
The natural process through which heat is retained in the troposphere is called the "greenhouse effect."2° The
greenhouse effect traps heat in the troposphere ihrough a three fold process summanzed as follows: Short wave
radiation emitted by the Sun is absorbed by the Earth; the Earth emits a portion of this energy in the form of long
wave radiation, and greenhouse gases in the upper atmosphere absorb ihis long wave radiation and emit this long
wave radiation into space and toward the EaRh. This "trapping° of the long wave (thermal) radiation emitted back
toward the EaRh is the underlying process of the greenhouse effect.
Without the greenhouse effect the Earth's average temperature would be approximately -18 degrees Celsius (°C)
(0° Fahrenheit [°f]) instead of its present 14°C (57°F). The most abundant greenhouse gases are water vapor and
carbon dioxide. Many other trace gases have greater ability to absorb and re-radiate long wave radiation; however,
these gases are not as plentiful. For this reason, and to gauge the potency of greenhouse gases. scientists have
established a Global Warming Potential (GWP)for each greenhouse gas based on its ability to absorb and re-radiate
long wave radiation. The GWP of a gas is determined using carbon dioxide as the reference gas with a GWP of one
(1).
Greenhouse gases include, but are not limitetl to,the following:21
• Ca�bon Dioxide (COz). COz is primarily generated by fossil fuel combustion in stationary and mobile
sources. Due to the emergence of industrial facilities and mobiie sources in the past 250 years, the
, concentration of COz in the atmosphere has increased 35 percent.22 COz is the most widely emitted
greenhouse gas and is the reference gas (GWP of 1) for determining GWP s for other greenhouse gases.
In 2004, 83.8 percent of Callfomia's greenhouse gases emissions were CO2.23
• Nitrous Oxide (Nz0), N20 is produced by both natural and human related sources Primary human related
sources include agncultural soil management, animal manure management, sewage treatment, mobile and
stationary combustion of fossil fuel, adipic acid production, and nitric acid production. The GWP of N20 is
310.
. Methane ICH,1. CH, is emitted from biogenic sources, incomplete combustion in forest fires, landfills,
manure management. and leaks in natural gas pipelines. In the United States, the top three sources of CHa
come from landfills, natural gas systems, and enteric fermentation. CH, is the primary component of natural
gas, which is used for space and water heating, steam production, and power generation The GWP of CH,
is 21.
Other greenhouse gases include, but are not limited to, chlorofluorocarbons, sulfur hexafluoride, hydrofluorocarbons, I
and perfluorocarbons.
�� The�roposphere is the botlom layerof the atmosphere,which varies in height from Ihe Earth�s sudace to 10 to 12 ktlometers.

Methodology
Per the Attorney General's Office. fheir recommended General Plan (including the Housing Element) measures will
reduce greenhouse gas emissions and the effects of global warming �d Additionally. the Climate Action Team Report
to Govemor Schwarzenegger at the Legislature (CAT Report) provides "overarching recommendations considered
essential by the (Climate Action Team) in meeting the statewide climate change emissions reduction targets" and
"lays out a path fonvard to ensure that California's climate change emission reduction targets are met." The CAT
Report identifies strategies designed to reduce California's greenhouse gas emissions and meet AB 32 and EO S-3-
05 goals. Therefore, compliance with all applicable CAT Report strategies and Attorney General's General Plan
recommendations wouid ensure the proposed Housing Element Project would help achieve the AB 32 and EO 5-3-
05 goals to reduce greenhouse gas emissions for Califomia and would result in a less than significant impact. ,
The California Air Pollution Control Officers Association (CAPCOA) identifes various approaches to global climate
change. The CAPCOA approach utilized in this analysis is identified below:
The emissions associated with a [general plan] are assumed to have a significant impact unless one can
arrive a[a less-than-significant finding by... the[methodology] below:
1 Demonstrate that a General Plan(GP)or a Regional Plan(RP)is in Compliance with AB 32:
• For most GPs or RPs [his will require demonstration [hat projected ... emissions will be equal
to or less than 1990 emissions.
• GPs or RPs are expected to fully document 1990 and[future] GHG�greenhouse gas�emission '
inventories.
• Projection of... emissions is complicated by the lact that CARB is expected to promulgatc
emission reductions in the short term. Until explicit CARB regulations are in placc,
unmitigated GP... emission inven[ories represent business-as-usual scenarios.
• EIRs for GPs or RPs which demonstrate[future) mitiga[ed emissions are less [han or equal to
7990 emissions are considered less[han significant.
Global Climate Change Analysis
Population growth anticipated to occur under the Housing Element which was anticipated by the General Plan, is
expected to result in increased emissions of greenhouse gases. largely due to increased vehicle miles traveled
(VMTs). as well as increased energy consumption and waste generation. As discussed previously, increased
emissions of greenhouse gases could contribute to global climate change pattems and the adverse global
environmental effecfs thereof. Increased concentrations of greenhouse gas emissions could also potentially conflict
with the requirement of AB 32 to reduce Statewide greenhouse gas emissions to 1990 levels by 2020.
Construction Emissions
CEQA does not require an agency ro evaluate an impact that is "too speculative," provided that the agency identifies
the impact, engages in a "thorough investigation" but is "unable to resolve an issue," and then discloses its
conclusion that the impact is too speculative for evaluation. (CE�A Guidelines Section 15145, Offce of Planning and
Research Commentary). Additionally, CEQA requires that impacts be evaluated at a Ievel that is "specific enough to
permit informed decision making and public participation" with lhe "production of information sufficient to understand
the environmenlal impacts of the proposed Project and to permit a reasonable choice of altematives so far as '

An EIR on a project such as [he adoption or amendment o(a comprehensive mning ordinance or a local
general plan should focus on the secondary effects that can be expected [o lollow (rom the adop[ion or
amendmenG but[he EIR need not be as detailed as an EIR on the specific cons[ruction projects tha[might
follow.
Construction of future residential new and infill development projects would result in greenhouse gas emissions from
the use of construclion equipment However, details of these future construction activities are unknown at this time,
and therefore, cannot be quantified. Compliance with General Plan policies and implementation measures would
reduce construction-related emissions to a level below"business as usual."
Operational Emissions
Area sources include emissions from natural gas combustion, hearth (wood stovelfireplaces), landscaping
equipment, consumer products, and architectural coatings Indirect sources include emissions from energy
consumption and water conveyance. Mobile sources include emissions from passenger vehicles and delivery trucks.
Typically, mobile sources are the primary contributor of greenhouse gas emissions. However, consistent with the
General Plan, the Housing Element wouid discourage sprawl, encourage mixed use development, and encourage
public transportation.
' Comoliance with ihe Attomev Generai's Recommendations
The California Office of the Attorney General has established recommended measures for projects to mitigate
greenhouse gas emissions.25 A list of the Attomey Generafs recommended measures and the projecYs comp�iance
with each measure are listed in Table 4.7-1, Housinc�Element Update's Compliance with the Attorney General"s
Recommendations.
According to CEQA Guidelines Section 15002(a)(1), one of the basic purposes of CE�A is to, "Inform governmental
decision makers and the public about the potentiaL significant environmental effects of proposed activities." Senate
Bill 97 requires the Califomia Office of Planning and Research (OPR) to develop CEQA Guidelines for anarysis and,
if necessary, the mitigation of greenhouse gas emissions or the effects of greenhouse gas emissions ro the
Resources Agency by July 1, 2009. Additionally, it is the position of the State Legislature (as expressed in its
adoption of AB 32, The California Climate Solutions Act of 2006)that global climate change poses significant adverse
effects to the environment of the State of California and the entire world. Additionally, the State Legislature adopted
the public policy position that global climate change is, "a serious threat to the economic well-being, public health,
natural resources,and the environment of Califomia"(Health and Safety Code Section 38501).

The State Legislature has determined thaf, 'the potential adverse impacts of global warming include the exacerbation
of air quality problems, a reductlon In the quality and supply of water to the State from the Sierra snowpack, a rise in
sea leveis resulting in the displacement of thousands of coastal businesses and residences, damage to marine
ecosystems and the natural environment and an increase in the incidences of infectious disease, asthma and other
human health-related problems" and that, "Global warming will have detrimental effects on some of California's
largest industries, including agriculture, wine, tourism, skiing, recreational and commercial fishing, and forestry
(and)...will also increase the strain on electricity supplies necessary to meet the demand for summer air-conditioning
in the hottest parts of the State" (Health and Safety Code Section 38501). These public policy statements became
law with the enactment of Assembly Bill 32, Statutes of 2006.
AB 32 requires that the CARB determine what the statewide greenhouse gas emissions level was in 1990, and
approve a statewide greenhouse gas emissions limit that is equivalent to that level, to be achieved by 2020. The
CARB has approved a 2020 emissions limit of 427 metric rons of COz equivalent (COzeq).26 By January 2009,
CARB must adopt mandatory reporting rules for significant sources of greenhouse gases and also a plan indicating
how reductions in significant greenhouse gas sources would be achieved through regulations, market mechanisms
and other actions. The relevant General Plan Policies that are designed to reduce VMT's, energy consumption, and
water consumption,and promote an overall level of reduced emissions, are outlined below.
It is noted that there are no established quantitative thresholtls of significance or methodologies in place to analyze
and determine the significance of global climate change with respect to a Housing Element. This analysis has been
formulated to comply with the purpose and intent of CEQA, as well as the guidance issued from CAPCOA and the
' Califomia's Attorney GeneraPs Office. Consistent with the General Plan, the Housing Element anticipates infll
residential and mixed-use development. Although, the automobile would continue to dominate as the main
iransportation mode, alternative transportation modes would be promoted through the General Plan's existing
policies and implementation measures. The Housing ElemeN would promote a range of affordable housing choices
near jobs, services, and transit, which would inherently reduce sprawl and thus total VMTs. The General Plan
estabiishes policies and implementation measures to reduce greenhouse gases by adopting and implementing the
PMAQMP, encouraging transportation demand management, improving traffic flow, encouraging energy
conservation, and reducing work trips. The General Pian also calls for the Town to minimize energy use, maximize
waste reduction and diversion, and implement water conservation measures. As indicated in Table 4.7-1, the
proposed Project woultl be in compliance with the recommended measures and strategies identified by the Attorney
General's Office.
4.7.a. Generate greenhouse gas emissions, either directly or indirectly, that may have a signfficant impact

Less Than Significant Impact See Section 4.3 (Air Quality) for additional information. Neither the Town nor
NSAQMD has a quantitative plan to measure requirements or significance thresholds established for greenhouse gas
emissions. Greenhouse gas emissions will be assessed when future residential development accommodated by this
Project is proposed. Mitigation measures will be adopted at the time of residential development approval. If the Town
adopts a Climate Action Plan or new measurement methods are established future residential development will be
required to meet the adopted standards.

Additionally. the lwo main generators of GHG emissions from land use development are vehide emissions and
building operations, In general. decreasing the expected amount and distance of vehicle trips can significantly reduce
the expected GHG emissions. The majority of the residential development accommodated by this Project is expected
to be infill development. Infill development increases tlensity and encourages residential developments to be built
close to existing services and destinations. Denser developments would create larger areas of people in need of
transportation which may lead to a higher demand of alternative transportation systems which would also reduce the
amount of vehicle trips generated in the future. In order to reduce greenhouse gas emissions through building
operations, all new developments will be constructed to meet or exceed the Califomia Building Energy Standards.

P14,3 Reduce automobile dependence, thereby reducing greenhouse gas emissions, by encouraging mixed
land use patterns that locate services such as banks, child care facilities, schools, neighborhood
shopping centers and restaurants in close proximity to employment centers and residential
neighborhoods.
P14.9 Require new development with the potential to generate significant quantities of ozone precursor air
poliutants to be analyzed in accordance with guidelines provided by the NSAQMD and appropriate
mitigation be applied to the project to minimize these emissions.

significant due to the limited amount of hazardous materials that would be generated by individual households.2' The
proposed Housing Element was considered in the GPEIR analysis, since additional residential development was
assumed. Therefore, Project implementation would be consistent with the analysis presented in the GPEIR, and
would result in no greater impacts involving the routine use of household hazardous materials than previously
identified. Future residents would have seasonal access to the household hazardous materials drop-off facility at the I
Eastern Regional Landfill in order to facilitate the proper disposal of household hazardous materials within the area.
Additionally,future residential development would be subject to compliance with the General Plan Policies that would
enable the safe disposal of household hazardous waste, With proper use and disposal, household hazardous
materials associated with future residential development would not create a significant hazard to the public or the
environment.
Mitigation Program: No further mitigation is required beyond compliance with the following General Plan Policy:

4.8.6. Create a significant hazard [o the public or the environment through reasonably foreseeable
' upset and accident conditions involving the release of hazardous materials into the
environment?
Less Than Significan[Impac[. The Town's future housing neetls woultl be accommodated within vacant land and
redevelopment Therefore, construction activities from future residential development accommodated by the Project
could release hazardous materials into the environment through reasonably foreseeable upset and accitlent
conditions.
Demolition. Since residential development would involve urban infill and redevelopment, existing structures may
need to be demolished prior to construction of new buildings. Although, specific development projects have not been
identifed, it is assumed that older buildings could potentially be demolished as residential uses are redeveloped.
Demolition of strucWres could expose construction personnel and the public to hazardous substances such as
asbestos containing materials(ACM) or lead-based paints(LBP), depending on the age of the structure. Further, the
potential exists that construction activities may release potential contaminants that may be present in building
materials (e g., mold, lead, etc.). In addition, the disturbance of soils and demolition of structures could expose
construction workers or employees to heatth or safety risks in the event contaminated structures andlor soils are
encountered during construction. Exposure couid occur from ACM or LBP in older buildings, or unknown
contaminants that have not previously been identified. Federal and State regulations govem the renovation and
demolition of structures where ACMs and LBPs are present. All demolition that could release ACMs or LBPs must
be conductetl acwrding to Federal and State standards. Adherence to existing regulations, which require
appropriate testing and abatement actions for hazardous materials, would ensure that impacts are less ihan
signifcant.
Soil and Groundwater Contamination Unknown Contaminated Sites. Grading and excavation for future development
under the proposed Housing Element could expose construction workers and the public to unidentified hazardous
' substances present in the soil or groundwater. Exposure to contaminants could occur if the contaminants migrated

to surrounding areas or if contaminated zones were disturbed at the contaminated location. Exposure to hazardous
substances would be considered significant unless mitigated. Additionally. the potential exists for unidentifed
underground storage tanks (USTs) to be present on a development site. Removal activities could pose risks to
workers and the public. Potential risks would be minimized by managing the tank according to existing Nevada
County standards, as enforced and monitored by the Environmental Health Department Health. Potenliai impacts to
groundwater would be dependant on the type of wntaminant, the amount released, and depth to groundwater at the
time of the release. If groundwater contamination is identified, remediation activities would be required by the
Regional Water Quality Control Board prior to the commencement of construction activities. Compliance with
measures established by Federal. State, and local regulatory agencies is considered adequate to offset the potential
negative effects related to the reasonably foreseeable upset and accident conditions involving the release of
hazardous materials.
Mitigation Program: No furlher mitigation is required beyond compliance with the following General Plan Policy:

No Impact Future residential development accommodated by the Project would not emit or handle hazardous or '
acutely hazardous materials. Therefore. no impacts(o school facilities would occur in this regard.
Mitigation Program: No mitigation is required. ��
4.8.d. Be located on a site which is included on a lis[of hazardous materials sites compiled pursuant
to Government Code Section 65962.5 and, as a result, would it create a significant hazard to the
public or the environment?
Less Than Significan[ ImpacL As discussed in Response 47 b, above, the potential exists that adverse
ernironmental conditions were created by previous uses on the future residential development sites. Also, the i
potential exists that some housing developments may be located on or near hazardous materials sites Through the
Town's environmental review process, it would be determined if a Phase 1 Environmentai Site Assessment would be
needed to assess whether hazardous materials, on or within the vicinity of the future residential sites,would pose any
significant hazards to the public or the environment. If necessary, mitigation would be identified to reduce potential
hazardous materials impacts to a less than signifcant level.
Mitiga[ion Program: No mitigation is required.
4.8.e. For a project located within an airport land use plan or, where such a plan has no[ been
adopted, within two miles o(a public airport or public use airport, would the project result in a

Impact AdequatelyAnatyzed in GPEIR. The Truckee Tahoe Airport. which serves as a regional center for private
and charter flights. is located outside of Truckee Town limits. straddling the boundary between Nevada and Placer '
Counties In December 2004. the Foothill Airport Land Use Commission adopted the Truckee Tahoe Airport Land

ensuring the orderly expansion of the airport and the adoption of land use measures that minimize the public's
exposure to excessive noise and safety hazards within areas around the airport to the extent that these areas are not
already devoted to incompatible uses. The ALUC describes a series of land use safety and compatibility zones and
associated guidelines for development around the Truckee Tahoe Airport that are intendetl to safeguard against
incompatible development adjacent to the airport. The influence area for the Truckee Tahoe Airport, as tlefined by
the ALUC, extends approximately 27 miles from the airport runways. Future residential development could
potentially occur within the airport influence area, thus, could result in a safety hazard for people residing in the future
housing.
The GPEIR concluded General Plan implementation would involve development within 2.0 miles of the Truckee
Tahoe Airport, resulting in potential impacts related to airports or airstrip safety. However, as a result of General Plan
Policies, General Plan implementation would not result in a significant impact on safety related to operation of the
airport or airstrip.2e The proposed Housing Element was considered in the GPEIR analysis, since additional
residential development was assumed. Therefore, Project implementation would be consistent with the analysis
presented in the GPEIR, and would result in no greater impacts involving airport safety hazards than previously
identifed. Future residential development would be subject to compliance with the General Plan Policies intended to
minimize risks associated with Truckee Tahoe Airport operations and including setback and height requirements
consistent with the adopted ALUC, in order to protect public safety. Moreover, future residential development would
be subject to compliance with Truckee Development Code Chapter 18.64, Truckee-Tahoe Airport Area Restric[ions,
which regulates land uses in the vicinity of the Truckee-Tahoe Airport and below areas where aircraft perform
approach and departure maneuvers, in order to protect people and property both in the air and on the ground (and to
� minimize noise and other conflicts between airport operations and surrounding land uses),
Mitigation Program: No further mitigation is required beyond comptiance with the following General Plan Policies:

4.8.1. For a project within the vicinity of a private airstrip, would the project result in a sa/ety hazard
for people residing or working in the project area?
No Impact There are no private airstrips located in the Town's vicinity. Therefore. Project implementafion would not
result in a safety hazard associated with a private airstrip for people residing in the area.
Mitigation Program: No mitigation is required.
4.8.g. Impair implementation of or physically interfere with an adopted emergency response plan or
emergency evacuation plan?
Impact Adequately Anatyzed in GPEIR. The Town has drafted an Emergency Operations Plan (EOP), which
identifies the Town's emergency planning, organization, and response policies and procedures. The EOP addresses
how the Town will respond to extraordinary events or disasters, from preparation through recovery, and identifies the
responsibility of each department based on each Identifed hazard or threat. Future residential development could
impair implementation of or physically interfere with the Town's EOP.
The GPEIR concluded the General Plan could result in new development and population growth, which could affect
the implementation of adopted emergency response and evacuations plans during disasters. The General Plan
Policies and actions would reduce the potential emergency preparedness impact to a less than significant level.�
The proposed Housing Element was considered in the GPEIR analysis, since additional residential development was
assumed. Therefore, Project implementation would be consistent with the analysis presented in the GPEIR, and '
would result in no greater impacts involving emergency preparedness than previously identified. Future residential
development would be subject to compliance with General Plan Policies, which plan for adequate emergency
response to protect existing and future development in Truckee, and support the Truckee Fire Protection District.

the Project could potentially expose people or structures to a significant risk of loss, injury, or death involving wildland
fires. Calculation of threat from wildfire hazartl would be based on a number of combining factors induding fuel
loading (vegetation), topography, and climatic conditions such as winds, humidity, and temperature.
The GPEIR concluded new development, particularly in more outlying and rural areas, could expose new populations
to wildfire hazards, however, implementation of the General Plan goal and policies would reduce potential impacts to
a less than significant level.30 The proposed Housing Element was considered in the GPEIR analysis, since
additional residential development was assumed. Therefore, Project implementation would be consistent with the
analysis presented in the GPEIR, and would result in no greater impacts involving wildland fires than previously
identified. Future residential development would be subject to compliance with General Plan Policies, which are
aimed at minimizing loss of Ilfe and property from wildfires, and include requirements for new development to I
incorporate adequate emergency water flow, emergency vehide access, and evacuation routes Policy compliance
would ensure that the development review process addresses wildland fire risk, including assessment of both
construction- and project-related fire risks, particularly in areas of the Town most susceptible to fire hazards, Future
residential development accommodated by the Project would not expose people or structures to a significant risk
involving wildland fires.

Safetv Element
, P4.2 Continue to cooperate with the Fire Protection District to implement fire safety ordinances to minimize
wildland fire hazards, including incorporation of fire resistant building and roofing materials, and
attainment and maintenance of "defensible space." Defensible space may include revegetation with

prevent erosion on bare soi�.
P4.3 Promote fire hazard reduction through cooperative fuel management activities in association with the
Truckee Fire Protection District, the California Department of Forestry and the U.S, Forest Service.
Such strategies may include identifying and implementing opportunities for fuel breaks in very high fire
hazard severity zones, and ensuring that fire breaks are provided where necessary and appropriate.
P4,4 Require new development to incorporate adequate emergency water flow, emergency vehicle access
and evacuation routes.
P4.5 Continue to suppoR the mitigation fee program for the Fire Protection District to ensure that the District
is able to meet the future fire protection needs of the community as it grows.
P4.6 Support, as appropriate, efforts to implement the recommendations of the 2005 Nevada County Fire

P4.7 Ensure that the development review process addresses wildland fire risk, including assessment of both
construction- and project related fire risks particularly in areas of the Town most susceptible to fire
hazards. Cooperate with the TFFPD in reviewing fire safety plans and provisions in new development,

Short-Term Construction. The SWRCB adopted NPDES General Permit No. CAS000002, Waste Discharge
Requirements (WDRs) for Discharges of S[ormwater Runofl Associated With Construction Activiry (General
Construction Permit). Construction sites with 1.0 acre or greater of soil disturbance or less than 1.0 acre, but part of
a greater common plan of development, are required to apply for coverage for discharges under the General
Construction Permit by submitting a Notice of Intent (N01) for coverage, developing a Stormwater Pollution
Prevention Plan (SWPPP), and implementing Best Management Practices (BMPs) to address construction site
pollutants, Construction activity subject to this permit includes clearing,grading, and disturbances to the ground such
as stockpiling or excavation, but does not indude regular maintenance activities.
Construction of future residential developmeN has the potential to produce typical pollutants such as nutrients, heavy
metals, pesticides and herbicides, toxic chemicals related to construction and cleaning, waste materials including
wash water, paints, wood, paper, concrete, food containers and sanitary wastes, fuel and lubricants. Additionally,
grading and construction activity can cause erosion, which can increase the sediment load of runoff. These non-
point source pollutants may flow into local surface waters or seep into the groundwater table and incrementally
degrade water quality.
Lonq-Term Operations. The SWRCB is responsible for issuing NPDES permits to cities and counties through
regional water quality control boards (RWQCB). The California SWRCB elected to adopt a statewide general permit
' (Water Quality Order No. 2003-0004-DWQ) for Small Municipal Separate Storm Sewer System (MS4s) operators to
efficiently regulate stormwater discharges under a single permit Permitees must meet the requirements in Provision
D of the General Permit, which require development and implementation of a Storm Water Management Plan
(SWMP) with the goal of reducing the discharge of pollutants to the maximum extent practicable. Currently. Truckee
is not subject to NPDES permit requirements because of its size.
Construction of future residential development would increase impervious areas and would increase the level of the
Town's activity. As a result, impacts to stormwater quality would occuc The Project would increase pollutant
loadings immediatety offsite and would potentially violate water quality standards. The pollutants that would be
expected with future residential development include typical pollutants found in stormwater runoff (i.e., sediment,
nutrients, trace metals.oxygen-demanding substances, bacteria, oil and grease, etc.j.
The GPEIR concluded that although the General Plan would allow new development that could contribute to erosion
and adtlitionai urban pollutants that may end up in the surface or groundwater systems, implementation of the Town's �
existing Development Code Standards, The Town of Truckee Downtown Specific Plan, The Downtown River
Revitalization Strategy, and the General Plan Policies and Actions would resuft in a less than signifcant impacts to
water quality.31 The proposed Housing Element was considered in the GPEIR analysis, since additional residential
development was assumed. Therefore. Project implementation would be consistent with the analysis presented in
the GPEIR, and would result in no greater short-term construction-related or long-term operational impacts to water
quality than previously identified. Future residential development would be subject to comptiance with General Plan
Policies, which control general erosion and runoff pollutants. Future residential development would be subject to
compliance with the Truckee Development Code, which contains specific requirements related to Best Management
Practices (BMPs) and other approaches designed to minimize erosion and runoff during construction and operation
of new development. More specifically, Truckee Development Code Section 18,30.050, Drainage and Smrm Water

Impact Adequately Analyzed in GPEIR. Water service in Truckee is provided by the Truckee Donner Public Utility
District (TDPUD), which operates three water systems in the Truckee area: the Hirshdale System, Truckee System
and Lahontan System. The TDPUD acquires its water from the Martis Valley Groundwater Basin. The basin
encompasses approximatery 57 square miles that are completely contained within a larger watershed of
approximately 167 square miles. The basin has a total subsurface storage volume of 484,000 acre-feet. Infiitralion
from surface water and precipitation supplies the upper unconfined aquifer system, which in tums feeds adjacent
wetland areas. Annual groundwater recharge depends heavily on snowmelt in the late spring and early summer.
The basinwide annual recharge is estimated at 29.165 AFY. Future residential development could impact
� groundwater supplies or interfere with groundwater recharge.
The GPEIR concluded available water is estimated to be adequate for the nexl 20 years, under General Plan
' implementation,32 Given the total subsurface storage and sustainable yield of 24,000 AFY, there would be enough
water available to serve projected buildout of the TDPUD service area (including Truckee), even if no recharge
occurred. Since recharge would in fact contribute additional water to the groundwater basin, actual water supplies
would be available beyond this 20-year horizon. The proposed Housing Element was considered in the GPEIR
analysis, since additional residential development was assumed. Therefore, Project implementation would be
consistent with the analysis presented in the GPEIR, and would result in no greater impacts to groundwater supplies
or recharge than previously identified. Future residential development would be subject to compliance with General
Plan Policies intended to conserve water. Project implementation would not substantially deplete groundwater
supplies or interfere substantially with groundwater recharge.

4.9.c. Substantialiy alter the existing drainage pattern of the site or area, inciuding through the
alteration of the course of stream or river, in a manner that would result in substantial erosion
or siltation on-or off-site?
Impac[Adequately Analyzed in GPEIR. Stormwater collection within the Town occurs through a mix of culverts,
drainage easements along propeRy lines, and roadside ditches that eventually discharge into the Truckee River
andlor Trout Creek Additionally, a formal storm drainage system exists within the Town's Downtown District lhat
discharges into the Truckee Rivec Future residential development would occur on vacant parcels. Drainage
pattems could be altered due to project-related grading and increases in the sites' impermeable surface areas from
structures and other areas (i.e.. parking lots, driveways, walkways, etc.). Grading and construction activity can cause
erosion, which can increase the sediment load of runoff, Altered drainage patters couid increase runoff voiumes and
velocities, which could create nuisance flooding in areas with inadequate drainage facilities.
The GPEIR concluded additional development and related construction allowed by the General Plan could impact
Truckee's drainage system by increasing storm water. which could require additional storm water drainage facilities.
The alteration of drainage patterns could also result in substantiai erosion, siltation or flooding on- or off-site.
However. implementation of General Plan Policies in concert with the Truckee Development Code's other
development standards and requirements would reduce the potential for impacts associated with drainage system
changes and increased runoff to a less-than-significant level.33 The proposed Housing Element was considered in
the GPEIR analysis, since additional residential development was assumed. Therefore Project implementation
would be consistent with the analysis presented in the GPEIR. and would result in no greater impacts involving

completed for new development in areas where geologic risks are known to exist and that these reports inclutle
recommendations for appropriate engineering and other measures to address identifed risks. General Plan Policies
also require that stormwater drainage systems be incorporated into development projects to effectively control the
rate and amount oi runoff, so as to prevent increases in downstream flooding potential. Requirements for new or
upgraded facilities would be determined largely by the scale of a specific project and its demand on existing storm
water drainage infrastructure. Additionally, future residential development would be subject to compliance with
various Truckee Municipal Code provisions that address drainage and soil erosion. Truckee Development Code

Boundary or Flood Insurance Ra[e Map or other flood hazard delineation map?
Impact Adequately Analyzed in GPEIR. The Federal Emergency Management Agency (FEMA) prepares and
maintains Flood Insurance Rate Maps (FIRMs), which show the extent of Special Flood Hazard Areas (SFHAs) and
other thematic features related to flood risk, in participating jurisdictions To receive insurance benefits in the event
of flood, participating agencies must recognize these offcial flood boundaries and establish appropriate land use
policy for the flood zones. GPEIR Figure 4]-1, Areas Subject ro Flooding, identifes flood prone areas within the
100-year floodplain along the banks of the Truckee River, around the Donner Lake shore, along Donner Creek, lower
Trout Creek, and Coldstream Creek. The 100-year floodplains for other minor streams have also been identified.
The 100-year flood (one percent annual chance flood), also known as the base flood. is the flood that has a one
percent chance of being equaled or exceeded in any given year. This SFHA is the area subject to flooding by the
one percent annual chance flood. The 100-year floodplain of the Truckee River varies in width and location. In some
locations, the floodplain is contained within the river banks, while in others, extensive flooding could extend inland by
as much as 300 feet. In the event of a storm of greater intensity than the 100-year flood, extensive flooding could
extend inland by as much as 300 feet in additional locations. Future development accommodated by the proposed ,
Project would not place structures or housing within a 100-year flood hazard area since the LRWQCB regulations

prohibit the construction of buildings or parking lots within the 100-year floodplain. Notwithstanding,the potential for
flooding exists beyond the floodplain.
The GPEIR concluded flooding is a serious concem in several paris of Truckee, particularly within those areas within
FEMA 100-year flood zones, however, the potential for impacts associated with flooding are reduced to a less than
significant level, given the Truckee Development Code's existing provisions and implementation of General Plan
Policies and Actions.34 The proposed Housing Element was considered in the GPEIR analysis, since additional
residential development was assumed. Therefore, Project implementation would be consistent with the analysis
presented in the GPEIR, and would result in no greater impacts involving potential flooding than previously identified.
Future residential development would be subject to compliance with General Plan Policies that minimize the risk of
flooding including policies that discourage development within the Truckee River floodplain and adjacent to other
waterways and prohibit development within established setback areas from the Truckee River and other blueline
streams. Future residential development would also be subject to compliance with Truckee Development Code
Chapter 18.34. Floodplain,which provides regulations for development within areas of potential flood hazard, in order
to protect, conserve, and promote the orderly development of landlwater resources, protect human life and health,
and preserve the natural characteristics of stream corridors in order to moderate flood and stormwater impacts. The
potential impacts associated with flooding are considered less than significant given required compliance with
General Plan Policies and Truckee Development Code standards.
Mitigation Program: No further mitigation is required beyond compliance with the following General Plan Policies:

Mitigation Program: Refer to Response 4.9.g.
4.9.i. Expose people or structures to a significant risk of loss, injury or death involving (looding,

Impac[ Adequately Anatyzed in GPEIR. There are five dams in the Truckee area: the Prosser. Boca, and
Stampede Reservoir Dams are located north of Truckee, and the Donner Lake and Martis Creek Lake Dams are
located to the south. Structural failure at any of these could result in flooding, Future development accommodated
by the proposed Project could expose people or structures to risk irnolving fiooding, as a result of dam failure.
The GPEIR concluded that, aithough each dam has the potential to faii and to release a volume of water that could
result in severe short-term flooding. Truckee would not be significantly affected by potential inundation, and therefore,
release of water from them poses minimal risk.35 Given existing Truckee Development Code provisions and
implementation of General Plan Policies and Actions, the potential for impacts associated with dam inundation are
reduced to a less-than-significant level.� The proposed Housing Element was considered in the GPEIR analysis. '
since additional residential development was assumed. Therefore. Project implementation would be consistent with
the anatysis presented in the GPEIR, and would result in no greater impacts involving potential flooding due to dam
failure than previously identified. Furthermore, Flooding nsk for Truckee is addressed in the Town's EOP. Future
residential development accommodated by the Project would result in less than significant impacts involving the
exposure of people or structures to risk involving flooding as a result of dam failure.
Mitigation Program: No mitigation is required.
4.9 j. Inundation by seiche, tsunami, or mud(low?
Impact Adequa[ely Analyzed in GPEIR. A tsunami is a very large ocean wave caused by an undenvater
earthquake or volcanic eruption. Truckee is not at risk from tsunami due to its inland location.
A seiche is a surface wave created when a large body of water is shaken, often by an earthquake. Dams located in
seismically active regions may overtop due to seiching during seismic activity or from seismically-induced landsliding.
The resulting disaster couid affect downstream communities located in the dam inundation area. The risk of a seiche
occurring on Donner Lake during a strong seismic event is considerable given the size of the lake and its location on
the southwestern edge of the Town.3i Hillsides and slopes of unconsolidated material could pose a risk of mudflows
to the Town if these areas become saturated due to loss of brush cover combined with the subsequent accumulation
of water on the ground preceded by a period of heavy or sustained rain. As discussed in Response 4.6.c, steep
slopes (30 percent or greater) occur in several areas of Town. These steep slope areas, particularly where they
occur in conjunction with weak soils and vegetation loss. may present a significant hazard in Truckee Based on
these existing conditions,future residential development could be exposed to inundation by seiche or mudflow.

Regulatory Setting. All development within the Town limits must conform to the land use designations outlined in
the Truckee General Plan. Goals, policies. actions, and implementation measures contained in the Land Use
Element of the General Plan provide additional direction on how the various land use designations should be
developed in order to contribute to the overall character of Truckee. Per state law, the Town's General Pian is the
primary planning document and all other Town plans and policies must be consistent with it.
In addition to the Truckee Generai Plan, The Town of Truckee Development Code (Truckee Municipal Code. Title 1 S) '
is the main reguiatory documem ihat affects land use pianning in Truckee, It is the primary regulatory mechanism I
used by the Town to carry out the goals, objectives. and policies of the General Plan. The Development Code, which �
was adopted in November 2000, and last amended in September 2013. contains regulations concerning the Town's
zoning, land use, and subdivisions. These regulations include most of tne Town's requirements for the development
and use of private and public land, buiidings, an structures within the Town.
The Truckee-Tahoe Airport,which is owned and operated by the Truckee-Tahoe Airport District, is located outside of
Truckee limits. Maintaining land uses compatible with safe airport operations is an important consideration. The
Airport Land Use Compatibility Plan was adopted in December 2004 and descnbes a series of land use safety and
compatibility zones and associated guidellnes for development around the Airport that Intended to safeguard against
development that is incompatible with airport operations.
4.10.a. Physically divide an es[ablished community?
Impact Adequately Analyzed in the GPEIR. Existing land use pattems in Truckee are reflective of the community's
historic development pattems. the land use planning that occurred prior to Truckee's incorporation. and the more
recent policies established through the Town's own land use policy framework. Figure 4.8-1. 2006 Exis[ing Land
Use, illustrates the Town's existing land uses. Approximately 30 percent of the Town is vacant or undeveloped, and
another 25 percent is in open space. Remaining land within the Town limits is developed with residential,
commercial, industrial, and institutional development. Future residential development is not anticipated to physically
divide the community, since it would be located primarily to achieve consistency and continuity with the existing
residential land uses.
The GPEIR concluded the General Plan's land use designations have been made, in part. to achieve consistency '
and continuity between various land uses. Additionally. lhe Town has spatially grouped similar types of land uses
through the 2025 General Plan Lantl Use Map, General Plan implementation would result in less than significant

land use impacts associated with the physical division of an established community, as a result of the General Plan
Goals and Polices 35 The proposed Housing Element was considered in the GPEIR analysis, since additional
residential development was assumed. Therefore, Project implementation would be wnsistent with the analysis
presented in the GPEIR, and would result in no greater impacts involving the physical division of an established
community than previously identified. Future residential development would be subject to compliance with General
Ptan Policies that were developed in large part to address some of the Town's existing discontinuous development
pattems and the physical barriers that divide the community.
Mitigation Program: No further mitigation is required beyond compliance with the following General Plan Policies:
Communitv Character Element
P5.1 Ensure that planning and development decisions are oriented towards the maintenance of Truckee's
unique character, reflecting the following considerations:
• Identification of specific types of centers. residential neighborhoods, employment districts, corridors
and gateways
• Respect for the quality, character and context of existing deveiopment within these different areas
of the town.
• Ensuring that new development enhances the desired character of each of these areas.
• Discouraging new architecture that directly mimics or is derivative of the buildings of the historic
' downtown.
• Encouraging the retrofit or rehabilitation of existing buiidings to more closety comply with Town
policies. standards and guidelines for high quality architecture and design.
• Consideration of the relationship of the built environment to the qualities and context of the
landscape and natural environment in which it is situated.
P52 Require all new development to incorporate high quality site design, architecture, and planning so as to
enhance the overall quality of the built environment in Truckee and create a visually interesting and
aesthetically pleasing town environment.
P5.5 Enhance physical connections between adjacent uses and between different parts of Truckee,
Circulation Element
P2.4 Improve connectivity throughout the Town's roadway network, through roadway improvements, while
minimizing environmental,circulation,and residential neighborhood impacts. This should include:
. New and improved links between roadways of the same classification.
• New andlor improved links between higher and lower capacity roadways where such connections
would not negatively impact the lower capacity roatlway's operations or local neighborhood
character, would be consistent with community character and environmental goals described
elsewhere in the General Plan, and would not result in redesignation of a lower classification
roadway to a higher classification, unless shown as such on the Circulation Plan.
• Discouraging the use of local and residential neighborhood roadways as through routes.

Impact Adequately Analyzed in GPEIR. The Town did not complete the rezones required to meet the 4� Cycle
Housing Element RHNA requirements. During the 2007-2014 Housing Element Cycle, the Town of Truckee was
assigned a RHNA of 1259 rotal units, The Town approved or constructed 1.365 units affordable to very low, low,
moderate and above moderate incomes, however not all income categories were adequately addressed. Given the
current number of units, buiit, approved, or under construction, the Town is required to accommodate an additional
493 units affordable to very low, low, and moderate income levels. The Town currently has land capacity to
accommodate at least 98 units that would be affordabfe to very low antl low income households and 91 units
affordable to moderate incomes. Based on the current land capacity. the Town must rezone additional land to meet
the RHNA shortfall of 302 lower income units for the 2007-2014 planning penod. In order to meet this RHNA need.
the Town will rezone up to seven sites to high-density residential. This would require additional steps to amend the
Zoning Map and to ensure consistency among all Town documents. However, all the sites identified to meet this �
need are designated as high density residential or commercial in the General Plan. '
Additionally, the Town is required to meet the RHNA goals for the 5�^ Cycle Housing Element(2014-2019). To enable '
the Town to meet RHNA construction goals. the Town has evaluated its capacity to meet future needs based on
existing development capacities. There are sites in the Town currently available to accommodate a portion of the
Town's lower and moderate income RHNA need utilizing current zoning and tlevelopment standards These sites
have the capacity for the development of 189 dwelling units (98 affordable to low-income households and 91
affordable to moderate-income households). After accounting for units constructed, under construction or approved.
and sites currently available to accommodate the lower- and moderate-income needs, the Town has a remaining
RHNA need of 181 units affordable to lower-income households. To accommodate its remaining lower-income RHNA
need, the Town would need to rezone a minimum of 12.1 acres to permit by-right residential development at a
minimum nel density of 15 dwelling units per acre. Upon approval of future residential development. Town
documents may need to be updated to ensure consistency,
The GPEIR concluded, where current Town documents may become inconsistent, the proposed General Plan
includes actions to update these planning documents and to conduct further. more detailed planning for sites and
properties.°0 All fulure residential projects would be subject ro review under the Town's environmental and design
review process. Additionalty, due to the conceptual nature of the future residential development, proposals would
require individual assessments to ensure consistency with the Town's General Plan, Development Code, and other
relevant planning documents. If necessary. appropriate mitigation would be identifed to avoid or reduce impacts.
Califomia Govemment Code Section 65300.5 requires intemal consistency among various elements of the General
Plan. Town staff has reviewed the other elements of the General Plan and has determined that the proposed �
Housing Element provides this necessary consistency. The Town would maintain this consistency, as future General
Pian amendments are processed, by evaluating proposed amendments for consistency with all General Plan
Elements.

Impact Adequately Analyzed in GPEIR. GPEIR Figure 4.5-2, Mineral Resources, maps the locations of the
important mineral resource areas (as defned by the State of California) that exist in Truckee. As illustrated in Figure
4.5-2, these resources are generally associated with alluvial deposits along the length of the Truckee River Valley,
, although some mineral resources are associated with volcanic features, such as the Hirschdale cinder cone. Alluvial
aggregates consist of gravel. sand. and broken stone that are used in production of concrete and asphait;cinders are
also used for building and road construction materials. The residential development accommodated by the Project I
could result in the loss of a mineral resource. �
The GPEIR concluded General Plan implementation could result in a significant impact if it would result in the loss of
availability of a mineral resource identified as being of local or statewide impoRance. This could occur if development
were permitted that created land use incompatibilities with mining operations or othenvise preciuded access to
mineral resource areas. Potential impacts on the use and development of mineral resources were concluded as less
than significant, as a result of the General Plan Policies and Actions.^� The proposed Housing Element was
considered in the GPEIR analysis, since additional residential development was assumed. Therefore. Project
implementation would be consistent with the analysis presented in the GPEIR, and would result in no greater impacts
involving mineral resources than previously identifed. Future residential development would be subject to
compliance with General Plan Policies that protect economically viable mineral resources and related industries in
Truckee, while avoiding land use conflicts and environmental impacts from mining activities. It is further noted the
General Plan assigns the Public land use designation lands containing mineral resources. This designation would
generally not permit sensitive land uses such as residential development to occur in these areas. Project
implementation would result in a less than significant impact involving mineral resources.

State of California Guidelines
The State of California Office of Planning and Research (OPR) Noise Element Guidelines include recommended
interior and exterior level standards for local jurisdictions to identify and prevent the creation of incompatible land
uses due to noise The OPR Guidelines describe the compatibility of various lantl uses with a range of
environmental noise levels in terms of dBA CNEL The State of California Office of Noise Control has established
guidelines for acceptable wmmunity noise levels. The State Office of Noise Control defines an outdoor level of 60
dBA CNEL or less as being "normally acceptable"for residential uses.
Table 4 12-1, Noise and Land Use Comoati6ilitv Matrix, illustrates the State guidelines established by the State
Department of Health Services for acceptable noise levels for each county and Town. These standards and criteria
are inwrporated into the land use planning process to reduce future noise and land use incompatibi6ties This table
is the primary tool that allows the Town to ensure in(egrated planning for compatibility between land uses and
outdoor noise.
As shown in Table 4.12-1, the acceptable noise levels for residences are up to 65 A-weighted decibels (dBA) on the
community noise equivalent level (CNEL) scale, up to 70 dBA CNEL for schools, churches, libraries, hospitals, and
' nursing homes: and up to 75 dBA CNEL for office and commercial uses. The exterior noise standard is 65 dBA; the
interior noise standard is 45 dBA.

� Normally Acceptable-Specific land use is satisfactory,based on the assumption lhat any building is of normal conventional
construction,without any special noise insulation requirements.
� Conditionally Acceptable- New consiruction or development should be undertaken only after a detailed analysis of noise reduction
requirements is made and needed nase insulation feaNres included in design. Conventional constmction,but with closed windows and
fresh air supply systems or air conditioning,will normally suHice.
� Normally Unacceptable-New construction or development should generally be discouraged. If new construction or development does '
proceed, a detailed analysis oi noise reduction reqwrements must be made and needed noise insulation feaWres must be included in
the design.

Town of Truckee Noise Standards
Truckee Development Code Chapter 18.44, Noise, establishes standards for the elimination and regulation of noise
disturbances, in order to protect the health, safety. welfare, and living/working environments of those living and
working in the Town. According to Truckee Development Code Section 18.44.040. Exterior Noise Standards. "it shall
be unlawful for any person. at any location within the Town, to create any noise or to allow the creation of any noise
on property leased, occupied. owned, or othenvise controlled by the person, which does not comply with the
provisions of this Section, unless the provision of either Section 18.44.050 (Residential Interior Noise Standards) or
18.44.070 (Exceptions), below have been met." E�erior noise level criteria specified in Truckee Development Code
Section 18.44.040 are outlined in Table 4.11-2, Noise Standards By Receiving Land Use.
Pursuant to Truckee Development Code Section 18,44,070,A, Exceptions—Construction. The provisions of Truckee
Development Code Chapter 18.44 shall not apply to noise sources associated with non-single family residential
construction, provided the activities do not lake place before 7 00 AM or after 9:00 PM on any day except Sunday, or
before 9:00 AM or after 6:00 PM on Sunday The review authority may impose fuRher limitations on the hours and
day of construction or other measures ro mitigate signifcant noise impacts on sensitive uses.

Significance of Changes in Ambient Noise Levels
' Changes of 5.0 dBA or greater may be noticed by some individuals and, therefore, may be considered an
environmental impact, since under these conditions sporadic complaints may occuc Changes in community noise
levels of less than 3.0 dBA are normally not noticeable and are therefore considered less than significant.d2 Areas
where ambient noise levels exceed the established standards or where sensitive land uses are exposed to levels in
excess of 60 dBA These areas generally occur along freeways, toll roads, arterial and secondary roadways where
noise barriers have not been constructed.
4.12.a. Exposure o(persons to or generation of noise levels in excess o(standards es[ablished in the
local general plan or noise ordinance, or applicable standards ol other agencies?
Impact Adequately Analyzed in GPEIR. The Housing Element anticipates the development of additional housing
units, the construction and operation of which would generate both short-term and long-term noise impacts Short-
term noise impacts could occur during grading and construction. Construction activities have the potential to expose
adjacent land uses to noise levels between 70 and 90 decibels at 50 feet from the noise source. Construction
activities associated with future residential projects are anticipated to temporarily exceed the Town's noise standards.
The degree of noise impact would be dependent upon the distance between the construction activity and the noise
sensitive receptor. Long-term noise impacts would be associated with vehicular traffc tolfrom the site (including
residents and visitors), outdoor activities, and stationary mechanical equipment on site. To determine noise levels
and project-related impacts, specific information is needed for a particular project.
The GPEIR concluded residential development is proposed near I-80, SR 89, and SR 267, and also near the
Truckee-Tahoe Airport under the General Plan. Noise exposure along I-80 and the railroad, and near the airport,
could exceed "normally acceptable" levels for sensitive land uses. However, the General Plan Goals, Policies, and
Actions would reduce potential impacts associated with noise and land use compatibility fo a less-than-significant
