Ms. Nuri presented the project goals and objectives previously approved by the Board and described the purpose of the proposed PAWG. Chair Cyr opened the item to questions from the public who were in-person and present in the audience. Public comment opened at 1:14 p.m. Olga Bright asked the definition of cultural in the presentation. Ms. Nuri provided a definition of cultural resources as items that include non-natural components of the property such as those with archeological or historical significance. Public comment closed at 1:15 p.m. Planning and Natural Resources Committee Page 3 March 21, 2023 Ms. Nuri continued the staff presentation on the existing conditions and opportunities and constraints report, including public access, local and regional connectivity, historic and cultural resources, and operations and maintenance. Ms. Nuri also presented the transportation study objectives, data collection and background review, and the existing transportation conditions memo, including traffic volume, existing multimodal access, and line of sight assessments. Director Cyr requested and received information on the access to the driveways on Alpine Road and Los Trancos Road. Ms. Hugg explained additional analysis will need to be completed for the driveway. Director Gleason requested explanation of the public access analysis for the Los Trancos Road driveway. Ms. Nuri explained that the Los Trancos Road driveway is not appropriate for general public use, but other uses such as emergency or maintenance may be appropriate. Director Gleason requested clarification on bicycle accidents related to the automobile right-of- way as discussed in the traffic study list of accidents. Ms. Hugg confirmed that for the bicycle accidents related to the automobile’s right-of-way, they were related to automobiles having the right-of-way. Director Holman asked if the Town of Portola Valley provided comments on the access off Alpine Road. Ms. Nuri confirmed the District is in discussions with the Town of Portola Valley as part of the stakeholder and public engagement. General Manager Ana Ruiz explained the traffic study results for Alpine Road and Los Trancos Road were recently received and there are ongoing discussions with the Town of Portola Valley. The findings will need to be discussed with the Town given the scenic designation of Alpine Road. Ms. Hugg confirmed the Town of Portola Valley has not raised any issues thus far. Ms. Nuri continued the staff presentation on the public access framework, including considerations related to the protection of natural resources, cultural resources, and aesthetic resources, as well as important factors required for public access and operations and maintenance. Public comment opened at 1:39 p.m. Jerry Wittenauer spoke in support of the project as an equestrian trail rider. Public comment closed at 1:40 p.m. Planning and Natural Resources Committee Page 4 March 21, 2023 Ms. Hugg continued the staff presentation on the Hawthorns Public Access Working Group purpose, composition, and proposed working format. The composition will include representation from the County of San Mateo, County of Santa Clara, thematic working group members, board liaison, town liaison, and meeting facilitator. Director Holman inquired why one board liaison for the Hawthorns PAWG is proposed compared to two board liaisons for the La Honda PAWG. Ms. Hugg explained the Hawthorns project covers a smaller area than the La Honda project and staff scaled down the representation. Additionally, the Hawthorns PAWG will include representation from the Town of Portola Valley. Director Holman expressed gratitude in the explanation of the Hawthorns project area coverage and Town of Portola Valley representation. Ms. Hugg continued the staff presentation on the ward stakeholder recruitment process. Director Holman suggested each director submit a candidate and the Board of Directors would review all submissions to select the best qualified candidates. Director Cyr commented constituents in wards further away from the Hawthorns site may not have as much stakeholder interest compared to constituents who live closer to the Hawthorns site. Director Cyr agreed with the suggested inclusion of constituent representation from all wards to provide a diverse point of view. Director Cyr expressed support for the same format with a larger working group, with the Board selecting a representative from their ward. Director Gleason suggested Director selection of a constituent with a higher stakeholder interest even if not residing within the Director’s ward. Ms. Ruiz stated the property is smaller in terms of acreage but there are elements that are attractive to members of the public not living in the area, including it is accessible via roads and highways, and the grades are gentle and less strenuous. Director Holman agreed the property is attractive and explained the location is in an urbanized area of the Hawthorns property. Director Holman suggested staff present the process and explain the two options to the full Board. Ms. Hugg requested Committee confirmation for the options to present to the full Board for the ward representatives: (1) Each Director submits a candidate to be automatically appointed to the ward stakeholder working group; or (2) Each Director proposes a candidate, and the Board reviews the seven candidates and selects a certain number of stakeholders to be appointed to the ward stakeholder group. Planning and Natural Resources Committee Page 5 March 21, 2023 Ms. Ruiz provided additional information on the La Honda PAWG on the deliberate intent to have both local and broader geographical voices represented in working group to ensure robust deliberations that include a wide array of perspectives. Ms. Hugg confirmed the proposed intent is to have representation of both local and broader geographical perspectives in the working group, hence the ward representatives. Director Gleason expressed concern finding a person to nominate who resides further away from the Hawthorns project site. Director Gleason mentioned constituent proximity. Director Cyr expressed concern with balancing representation amongst local community members and those who can represent the broader District. Director Holman requested staff present the revised proposal that incorporates Committee feedback. Ms. Hugg confirmed the revised ward stakeholder recruitment process proposal, with Committee feedback, is as follows: 1. Each Director selects one person and the person is automatically appointed to the PAWG.* * Question for the full Board’s consideration: Does the person need to represent the Ward or is this at each Director’s discretion? 2. Each director nominates a representative and the full Board interviews and/or reviews an application/interest form and selects the top four candidates.* * Question for the full Board’s consideration: Does the person need to represent the Ward or is this at each Director’s discretion? Director Holman supported an application or interest form process over interviews. Director Cyr stated the full Board would appreciate having input on the process. Ms. Hugg continued the staff presentation on the working group member recruitment process, including the application, virtual informational meetings, public outreach efforts, and candidate selection for interviews. Candidate Selection for Interviews Scenario 1: Less than or Equal to 10 Application • The full Board would review all applications and interview all applications (approx. 15 min per interview). Scenario 2: More than 10 Applications • Option A: Staff would review the application and recommend the top ten applicants to interview with the full Board. • Option B: Each Board Director would review the applications and select the top ten applicants to interview with the full Board. • Option C: The Board would approve the formation of an Ad Hoc Committee to review the applications and select the top ten applicants to interview with the full Board. Planning and Natural Resources Committee Page 6 March 21, 2023 Director Gleason expressed support for Scenario 2: Option A. Director Holman requested and received information on the process of application review and legibility. Ms. Hugg explained current applications do not have limits on sections. Director Holman suggested illegible applications are discarded; the applications state applications not clearly readable will be discarded; and page limitations, including font size. Director Holman stated applicants should focus on qualification and experience that marries the task at-hand. Ms. Hugg stated staff will take the Director suggestions and check the online form for character and word limits, and staff will have a format that captures the limit and legibility. Director Cyr expressed agreement with Director Holman’s suggestions. Director Gleason asked if the application can be exclusively online. Ms. Hugg explained the District will offer a hard-copy application form for diversity, equity, and inclusivity, and previously applicants did mail an application for the La Honda PAWG. Director Holman expressed support for Scenario 2: Option B or Option C, as it is representative process. Director Cyr asked how many applications were reviewed of La Honda PAWG. Ms. Hugg stated La Honda PAWG received eleven applicants with two selected as stakeholders and the Board selected nine. Ms. Ruiz and Ms. Hugg explained there is a higher level of interest in the Hawthorns project. Ms. Ruiz states the neighborhood meeting had 60 attendees. Director Holman requested applications include verbiage on how to obtain assistance with completing the application, and on expected level of commitment for the PAWG (number and hours of meetings). Directors Cyr, Gleason, and Holman discussed the best options to forward to the Board and the threshold of applications. Director Holman suggested Option B for a lower number of applications and Option C for above the threshold. Directors Cyr, Gleason, and Holman agreed to forward to the full Board Scenario 2: Options B and C, with Scenario 2: Option C having a conditional formation of an Ad Hoc Committee if the applications reach above a threshold. General Counsel Hilary Stevenson stated previously the Board of Directors authorized the General Manager to call the formation of the Ad Hoc Committee when the time is right. Planning and Natural Resources Committee Page 7 March 21, 2023 Director Cyr expressed agreement with Ms. Stevenson. Ms. Stevenson reminded the Committee that the Board President has the ability to select the Ad Hoc Committee members. Ms. Hugg confirmed forwarding Scenario 1 and Scenario 2: Options B and C, with Scenario 2: Option C having a conditional formation of an Ad Hoc Committee if the applications reach above a threshold. Ms. Hugg continued the staff presentation explaining the interview and appointment process, candidate interviews, and working group appointments. Following Working Group Formation, Ms. Hugg explained the operations of the working group, tentative meeting schedule, and meeting objectives. Ms. Hugg explained the inclusion of Town of Portola Valley staff in the process thus far. Director Holman requested and received additional information on the Town of Portola Valley Ad hoc and interface with the District’s process. Ms. Hugg provided additional information on the Town of Portola Valley’s ten committees and six of the key committees each have one representative aggregated into an Ad Hoc Committee. Staff will meet with the Town of Portola Valley Ad Hoc Committee. Ms. Hugg explained the presentations of materials will be materials previously presented to the District’s Planning and Natural Resources Committee or Board. Director Holman asked if the meetings were public. Ms. Hugg confirmed the meetings are not public. Director Holman asked and received clarification on the Town of Portola Valley Ad Hoc Committee input. Ms. Hugg explained the Town of Portola Valley Ad Hoc Committee is part of the engagement process and will be invited to the District working group meetings. Director Holman asked, and Ms. Hugg confirmed, the Town of Portola Valley Ad Hoc Committee members are appointed and thus could not serve on the District’s Hawthorns working group. Director Holman asked, and Ms. Hugg confirmed, Town of Portola Valley Ad Hoc Committee members would be able to provide feedback during the District’s Hawthorns working group meetings. Director Gleason asked, and Ms. Hugg confirmed, the Town of Portola Valley Ad Hoc Committee is for the Hawthorns area. Planning and Natural Resources Committee Page 8 March 21, 2023 Director Holman asked if the Town of Portola Valley Ad Hoc Committee reports to the Town of Portola Valley Board and Commissions for feedback, and how will the District receive information and feedback. Ms. Hugg explained the Town of Portola Valley Ad Hoc Committee members would take updates back to their committees. The Town of Portola Valley Ad Hoc Committee will send alternates if the primary representative is unable to attend. The exact logistics and coordination with the Town of Portola Valley is in development. Director Holman requested clarification if there will be work product from Town of Portola Valley Ad Hoc Committee for presentation and utilization by the PAWG. Ms. Hugg explained that feedback from the Town of Portola Valley Ad Hoc Committee and the District’s Hawthorns PAWG will be included in staff reports and received by the Board of Directors. Director Gleason asked clarification of formal representative of the Town of Portola Valley Ad Hoc Committee on the District’s Hawthorns PAWG. Ms. Hugg explained the Town of Portola Valley Ad Hoc Committee is a conduit to the Town of Portola Valley committees and the Town of Portola Valley Ad Hoc Committee will provide feedback at the District’s PAWG meetings. The Town liaison is the official Town of Portola Valley representative on the District’s Hawthorns PAWG and is a Town of Portola Valley Council member. Ms. Hugg stated the Town of Portola Valley Town Manager felt this was the most effective way to share information and gather feedback from the various Town of Portola Valley committees. Director Cyr expressed support for inclusion of the Town of Portola Valley Ad Hoc Committee in the District’s Hawthorns process. Public comment opened at 2:54 p.m. Bonnie Crater stated she serves on the Town of Portola Valley Nature and Science Committee and spoke on her attendance on the District’s process thus far. Ms. Crater explained the Nature and Science Committee is interested in building a modest nature center on the property. Ms. Crater expressed appreciation for the staff report. Dave Evans asked the committee for the selection criteria of applicants (local family, mountain bikers, etc.) and the various perspectives that applicants can bring to the working group. Mr. Evans suggested setting criteria to represent a wide view point. Kristi Corley stated she did not see the Planning and Natural Resources Committee meeting on the Town of Portola Valley calendars and requested the District meetings be listed on the town calendar so attendees can provide comments. Ms. Corley asked for the District’s Town contact. She requested project planning keep housing sites and residences of Alpine Road in mind. She is not aware of the Town of Portola Valley Ad Hoc Committee formation. She spoke in support of open space, bike and pedestrian safety, and trails. Planning and Natural Resources Committee Page 9 March 21, 2023 In response to public comments, Ms. Hugg explained the District communicated with Town Manager Jeremy Dennis, and activities and events with Town Clerk Melissa Thurman. However due to Town of Portola Valley staffing changes, the current contact is now the Interim Town Manager Corie Stocker. Staff will discuss with the Town on how best to notify Town citizens about future meetings. Ms. Hugg explained the application criteria is mentioned in Attachments 5 and 6 of the agenda report. Ms. Hugg explained the Town of Portola Valley Ad Hoc Committees are the Town Meetings and will share feedback received today to Town of Portola Valley staff. Staff noted Alpine Road is in the scenic corridor, which is included in the existing conditions and opportunities and constraints analysis report. The Town of Portola Valley Ad Hoc Committee representation includes Open Space; Nature and Science; Historic Resources; Trails and Paths; Conservation; Bicycle, Pedestrian, and Traffic Safety; and Parks and Recreation. The Town of Portola Valley Ad Hoc Committee was formed by the Town Manager. Ms. Ruiz reminded members of the public can view the packet with attachments on the District’s website. Ms. Hugg stated there is a Hawthorns Area Plan project website with additional information. Public comment closed at 3:06 p.m. Chair Cyr called for a recess at 3:08 p.m. Chair Cyr resumed the meeting at 3:14 p.m. All committee members were present. Ms. Hugg continued the staff presentation for conclusion and next steps. Director Holman asked for an explanation on the interface between the public access working group and the site planning for the historic complex, and the timing of the historic complex. Ms. Hugg explained that the PAWG will look at trail connections to the historic complex and that trails to the historic complex will likely be phased. Director Holman requested clarification on Phase II. Ms. Hugg explained Phase I is the Hawthorns Area Plan and Phase II is the connection to the complex. Ms. Ruiz explained the current status of investigations regarding the Hawthorns Historic Area, including the completion of a structural assessment for each building and various disposition options with costs estimates for all 13 buildings. Staff is currently reviewing the information and is preparing to solicit input on the various options from the Town of Portola Valley staff. All of this information will be brought to the Board of Directors for consideration. Director Holman inquired on the timing. Ms. Ruiz stated the goal is to bring forward the information to the Town of Portola Valley in Fall 2023, and, unless there are additional studies, bring the information to the Board by end of 2023. Director Holman asked about the potential partner. Planning and Natural Resources Committee Page 10 March 21, 2023 Ms. Ruiz explained that a potential partner is interested in potential public programming for the site.

ROLL CALL VOTE: 3-0-0 ADJOURNMENT Chair Cyr adjourned the meeting of the Planning and Natural Resources Committee at 3:25 p.m. Loana Lumina-Hsu Acting Deputy District Clerk Rev. 3/15/21 PLANNING & NATURAL RESOURCES COMMITTEE R-23-38 April 4, 2023 AGENDA ITEM 2 AGENDA ITEM Highway 35 Multi-Use Trail Crossing and Parking Feasibility Study located at and near the North Ridge Parking Area of Purisima Creek Redwoods Open Space Preserve – Review of Project Goals and Existing Conditions/Site Opportunities and Constraints Analysis GENERAL MANAGER’S RECOMMENDATIONS 1. Receive a presentation on the Highway 35 Multi-use Trail Crossing and Parking Feasibility Study, including Project Goals and the Existing Conditions/Site Opportunity and Constraints Analysis. 2. Provide feedback on parking capacity and multimodal access elements to evaluate through the next phase of Project work as part of the development of parking area conceptual design alternatives. SUMMARY The Highway 35 Multi-Use Trail Crossing and Parking Feasibility Study (Project) is a partnership between the Midpeninsula Regional Open Space District (District), San Francisco Public Utilities Commission (SFPUC), Bay Area Ridge Trail Council (Ridge Trail Council) and Peninsula Open Space Trust (POST). The Project is evaluating a multi-use trail crossing location and connector trail in the northeastern reaches of Purisima Creek Redwoods Open Space Preserve (Purisima, Preserve), as well as the potential expansion of the North Ridge parking area. At the April 4, 2023 Planning and Natural Resource (PNR) Committee meeting, staff will present the Project goals and the initial findings of the feasibility study, including results from the Existing Conditions/Opportunities and Constraints Analysis. In addition, staff will seek feedback from the PNR Committee on the parking capacity and multimodal access elements to evaluate through the next phase of Project work as part of developing the parking area conceptual design alternatives. BACKGROUND The District is conducting a feasibility study to identify a trail crossing location from the Purisima North Ridge parking area across Skyline Boulevard (Highway 35) to connect existing segments of the Bay Area Ridge Trail within Purisima, west of Highway 35, to a new segment of the Bay Area Ridge Trail planned on the east side of Highway 35 (Ridge Trail Extension). The feasibility study will also analyze the potential expansion of the North Ridge parking area to serve visitors to both the existing Preserve trailhead and to the proposed Ridge Trail Extension. R-23-38 Page 2 The Highway 35 Multi-use Trail Crossing and Parking Study (Project) is a partnership between the District, SFPUC, Ridge Trail Council, and POST. DISCUSSION Project Goals The intent of the Project is to enhance regional connectivity through a multi-use trail crossing that will allow access to trails on both sides of Highway 35 and to identify ways to reconfigure and increase parking capacity at the North Ridge parking area. Project goals and strategies have been identified to guide the development of Project elements and evaluate Project success. Goal 1: Support the implementation of the regional Bay Area Ridge Trail. Strategies: • Identify a multi-use trail crossing and trail spur location to connect the SFPUC’s new segment of the Bay Area Ridge Trail to the Preserve and the existing Ridge Trail segment within the Preserve. • Maximize safety and minimize neighbor impacts when evaluating multi-use trail crossing locations and infrastructure. • Develop the multi-use trail crossing and spur trail to accommodate low-intensity recreational use by hikers, bicyclists and equestrians, consistent with Bay Area Ridge Trail corridor goals. • Collaborate with partner agencies to complete the planning, design and implementation of the multi-use trail crossing and spur trail. Goal 2: Improve public access and visitor experience at Purisima’s North Ridge trailhead using ecologically sensitive design, construction practices, and long-term maintenance and management. Strategies: • Add parking capacity through the reconfiguration of existing parking spaces and expansion of the North Ridge Parking Area. • Improve the existing trailhead amenities, such as replacing the existing restroom with a new ADA compliant vault restroom, replacing dated signboards with current standard design, and adding bicycle parking. • Incorporate Transportation Demand Management Strategies consistent with the Board-approved Purisima Multimodal Access Study. • Design recreational amenities to protect the scenic corridor. • Maximize safety and minimize neighbor impacts when evaluating the multi-use trail crossing, parking enhancements and vehicle circulation. • Maintain routine patrols and maintenance and use adaptive management to address unforeseen issues that arise from increased visitation to the North Ridge trailhead. Existing Conditions The Project site includes an area west of Highway 35 within Purisima, comprised of the existing North Ridge parking area and adjacent open areas west of the parking area. The Project site also includes the Caltrans Highway 35 right-of-way and approximately four acres of SFPUC Watershed lands east of Highway 35 for the spur trail study area. R-23-38 Page 3 The North Ridge parking area and trailhead is the northernmost entry point into Purisima, located along Highway 35, and currently provides public access to hiking, biking, and equestrian trails within the Preserve. Purisima also contains existing segments of the Bay Area Ridge Trail, of which these segments contribute to over 400 miles (and counting) of existing multi-use trail that follow the ridgelines encircling the San Francisco Bay. A new alignment of the Bay Area Ridge Trail (Ridge Trail Extension) will be constructed on SFPUC Watershed lands east of the North Ridge trailhead, posing an opportunity to connect Purisima and its Bay Area Ridge Trail segment to the new trail extension through the Project’s multi-use trail crossing on Highway 35. With the implementation of this multi-use trail crossing, the North Ridge parking area can also serve as the southern staging area for future visitors of the Ridge Trail Extension. The North Ridge trailhead is surrounded by a rural, forested setting, primarily comprised of redwood forest with some annual grassland and Monterey cypress woodland. The area in the vicinity of the Project site is also sparsely populated with single family residences and businesses along the Highway 35 corridor. The existing North Ridge parking area is an unstriped gravel lot that can accommodate 41 standard parking spaces and 2 ADA parking spaces. Equestrian parking at the North Ridge lot is accommodated along the northwest boundary of the parking area, with space for approximately two equestrian trailers. The North Ridge trailhead includes standard trailhead amenities such as an equestrian hitching post, map and sign boards, a boot brush, and a single-stall vault restroom. As with many other District Preserves, the North Ridge trailhead receives peak visitation on weekends and the parking area, which currently only serves visitors to Purisima, frequently reaches capacity during peak visitation. Adjacent to the North Ridge parking lot is an open, flat area (upper expansion area) that is currently used as a helicopter landing zone for CalFire emergency response. Further west of this open area, the land slopes down and levels out to another open, flat area (lower expansion area) adjacent to a District employee residence. This lower expansion area can be accessed from the existing North Ridge parking lot via a separate driveway along the Preserve’s north property boundary. Technical Studies District staff contracted with professional consulting firms to complete various technical studies to analyze the biological, cultural, traffic, and topographic characteristics of the Project area. The findings of these studies are summarized below: Biological Resources Survey AECOM conducted a thorough Biological Resources Survey to identify any existing or potential biological resources within the Project area. This survey did not uncover any special-status wildlife species, nesting birds or raptors, aquatic resources, roosting bats, or other sensitive biological resources within the Project area. A Dusky-Footed Woodrat midden was found at a distance, about 250 feet from the Project area, which is unlikely to be affected by the Project. Due to the Project site’s proximity to Huddart County Park, which is designated critical habitat for the endangered marbled murrelet, District staff also conducted a site assessment for marbled murrelet and consulted with California Department of Fish and Wildlife (CDFW) about the potential need for special species protections. However, based on results of the site assessment and discussions with CDFW, both the District and CDFW staff confirmed that no suitable murrelet habitat is located within or in the vicinity of the Project area. R-23-38 Page 4 Phytophthora Risk Assessment AECOM also prepared a Phytophthora Risk Assessment in February 2023 to identify any risk of soil pathogen infection related to Project and to provide specific mitigation and best management practices. Analysis from this study found that the Project area within Purisima has relatively low levels of contamination risk, while areas east of Hwy 35 are highly receptive to potential contamination and are considered sensitive sites. Cultural and Historic Resource Surveys Cogstone Resource Management, Inc., conducted cultural and historic resource surveys in the fall and winter of 2022 to determine if any cultural or historic resources were present within the Project area that may be affected by the Project. No archaeological resources were observed during the survey and the background research did not find any previously recorded cultural or historical resources located within the Project area. A Sacred Lands File search identified one tribal band, which the District will contact for further information and guidance on any tribal cultural resources that may be present in the vicinity of the Project. The District will contact the tribe directly once preliminary concept plans are available and again when a design alternative is selected and the Project proceeds into the environmental review phase, as required by the California Environmental Quality Act (CEQA) and in accordance with Assembly Bill (AB) 52 consultations. No archaeological monitoring is anticipated due to the geological age of the soils as well as the absence of any known cultural resources within the Project area. In addition, a pedestrian survey of the Project site performed by Cogstone in the fall of 2022 did not identify archaeological resources within the Project site. An Historic Resources Evaluation was also conducted for the nearby onsite employee residence that was built over 50 years ago (circa 1948) given its proximity to the parking area. The residence includes Ranch style architectural elements such as a low pitch roof with a wide eave overhang. Due to a lack of significance and notable architectural alteration, the residence was not found eligible for listing at the local, state, or national level, and no further evaluation is recommended. No changes are proposed for this residence, which would remain in place as part of the Project and continued to be used as an employee residence to maintain onsite presence and vigilance of the property. Traffic Study TJKM Transportation Consultants (TJKM) evaluated the sight distance conditions for the two existing parking area driveways and the feasibility/design of a new on-grade trail crossing on Highway 35. Data collection from April 2022 was used to determine if adequate sight distance is available for vehicles exiting the existing driveways, and if northbound and southbound vehicles on Highway 35 have adequate stopping sight distance for a new on-grade trail crossing. TJKM also reviewed five years of traffic collision data within the vicinity of the project site to inform the final recommendations. Based on the available information, TJKM concluded that there is a feasible on-grade trail crossing location immediately adjacent to the existing exit driveway. TJKM recommends improvements within the right-of-way to maintain site distances and enhance visibility of the crossing. Furthermore, TJKM concluded that the existing driveway configuration is the most favorable for ingress and egress. TJKM has sought concurrence with the California Department of Transportation (Caltrans) on their findings and recommendations. Caltrans reviewed the findings and requested additional information in the final report, which was provided by TJKM. Caltrans does not have any further comments at this time. Additional coordination with Caltrans will be required for future encroachment permits, which would occur after a Board-approved alternative is selected and analyzed as part of the CEQA environmental review process. Additional details of the recommended crossing location and roadway improvements are shown in Attachment 1c. R-23-38 Page 5 Public Engagement From 2021 to 2022, the District engaged with stakeholder groups and partners as part of Project- focused meetings and at meetings that included the Purisima-to-the-Sea project and the Purisima Multimodal Access Study. These engagement activities were used to gather initial feedback on existing challenges at the North Ridge parking area and any desired amenities that should be considered for this parking area. The feedback received during the stakeholder engagement process has been incorporated into the opportunities and constraints analysis. Key engagement activities specific to the Highway 35 Multiuse Crossing and Parking Expansion project included: • Peninsula Trails Team (comprised of regional trails partners and land managers) – October 19, 2022 • Kings Mountain Association – March 15, 2022 and November 9, 2022 • Fisher Investments (neighboring property) – November 9, 2022 • Stakeholder group meetings – November 15 & 17, 2022 Feedback received includes the following 1: Theme/Topic General Feedback/Comments Traffic and Safety • Concerns related to providing a safe pedestrian roadway crossing due to current vehicle speeds on Highway 35. • Neighbors would like to see roadway striping and advanced warning beacon for the trail crossing. • Concerns related to roadside parking that create potentially unsafe roadway conditions for pedestrians and vehicles. • Suggestion to modify the parking area entrance to allow vehicles to turn into the parking area quickly. • Suggestion to provide historic traffic accident data in the vicinity of North Ridge to better understand safety issues. • Concerns related to foggy conditions on Highway 35 that could limit visibility. Parking and Visitor Capacity • Allowing E-bikes within the Preserve may reduce parking demand. • Request for better equestrian parking and access at this trailhead. • Better/clearer roadway parking signage can discourage parking along the roadway, which is impacting neighboring properties. Amenities • Support for the proposed trailhead amenities. • Suggestion to include emergency response information on trailhead signage. General • General support for the Project if concerns are addressed. • New regional trail connection may result in additional traffic and trash. • Concerns regarding relocating the CalFire helicopter landing zone and how this would impact fire response. 1 This feedback has been received in addition to previous feedback that was presented to the PNR Committee and the Board as part of the Purisima Multimodal Access engagement on August 2nd, 2022 (see attachment 5) . R-23-38 Page 6 Site Opportunities and Constraints Opportunities and Constraints for the Project are developed by analyzing the results of the technical studies and identifying site conditions that need to be considered for the multi-use trail crossing, spur trail, and North Ridge parking expansion. Key opportunities and constraints are summarized below, and additional details can be found in Attachment 1. Natural Resources: The biological survey did not uncover any special-status wildlife species, nesting birds or raptors, aquatic resources, roosting bats, or other sensitive biological resources within the Project area. Best Management Practices (BMPs) are recommended to avoid any impacts to nearby biological resources from future construction of the Project, including nesting bird surveys, San Francisco dusky-footed woodrat midden avoidance buffer, marbled murrelet avoidance and mitigation measures, BMPs to prevent Phytophthora and other pathogen contamination, and BMPs related to construction runoff and drainage. Public Access: The North Ridge parking area and trailhead currently provide public parking and access to Purisima, and the overall types of uses at this parking area and trailhead will not significantly change with the implementation of the Project. The traffic study identified a suitable multiuse crossing location on Highway 35 as well as roadway improvements to establish a safer crossing with sufficient lines of sight at this location. The North Ridge trailhead has two potential onsite locations that can provide additional parking; expansion of the parking area coupled with multimodal access strategies are expected to significantly alleviate parking demands and potentially meet anticipated parking needs at this trailhead. Local and Regional Connectivity: Existing segments of the Bay Area Ridge Trail within Purisima can be accessed from the North Ridge trailhead, which makes a multi-use trail crossing at Highway 35 from the planned Ridge Trail Extension to the North Ridge trailhead a natural and direct connection point. Cultural and Historic Resources: The cultural resources survey did not identify any previously recorded cultural resources within the Project area and no archaeological resources were encountered during the pedestrian survey. Aside from consultations with the recommended tribe for review of the preliminary concept plans and during the CEQA environmental review process, no further action is recommended regarding cultural or archaeological resources. The historic resource evaluation for the onsite employee residence found that the structure was not eligible for listing at the local, state, or national level and no further action is necessary for this structure (residence would remain in place and continue to be used as an employee residence). Aesthetics: Highway 35 is a state scenic highway and is therefore subject to both State of California and San Mateo County policies regulating development along scenic corridors. The Project will direct new development (parking areas and vault restroom) to areas away from the Highway 35 scenic corridor zone. There is also an existing vegetated barrier between the Caltrans right-of-way and the existing parking area, partially screening it from the highway. Changes visible from the highway may include the upper parking expansion area and the replacement vault restroom, which would be relocated to a more central location to address ADA barriers. The lower parking R-23-38 Page 7 expansion area is set further back from the roadway and at a lower elevation as compared to the existing parking area, making this area less visible from Highway 35. Operations and Maintenance: The North Ridge trailhead currently has electrical and cellular service available, which could support the implementation of new trailhead amenities and infrastructure, such as electric vehicle charging and real-time parking sensors. The existing vault restroom is in deteriorating condition and requires replacement with an ADA-accessible model and accessible path to meet ADA standards. Staff have reached out to the agencies and organizations that may utilize the landing zone at the upper expansion area, including CalFire, San Mateo County Fire, and the Kings Mountain Volunteer Fire Department. These organizations are aware of the Project and have not requested further coordination at this time. In addition, there are other landing zones located in the vicinity of the Project area that are currently used by these organizations. These nearby alternative landing zone locations include private properties on Cyprus Ridge Road, less than a mile north of the Project site, and Tunitas Creek Road, approximately two miles south of the Project site. The nearest alternative landing zone on District lands is located at El Corte de Madera Creek Preserve, approximately five miles south of the Project site. Should a Project alternative be selected for CEQA review that would change the use of the landing zone, District staff will engage in additional coordination with these agencies at that time to confirm the landing zone can be formally retired. Spatial Analysis and Parking Capacity The Project proposes to expand parking for passenger vehicles and horse trailers. The trailhead would have amenities typical to District preserves, including a vault restroom, trailhead signboards, boot brush, bike racks, and equestrian mounting block. The parking lot, trailhead, and restroom would meet ADA accessibility requirements. The Committee is asked to provide feedback on the share of passenger vehicle, horse trailer, and shuttle spaces that should be accommodated as part of the proposed parking expansion design. The share of spaces is based on the expansion potential that exists at the Upper Area, comprised of the existing parking area and the adjacent vacant area to the west, and the Lower Area, comprised of the vacant area adjacent to the employee residence. Staff completed a spatial analysis for the Upper and Lower Areas, which is detailed below (refer also to Attachment 1c). The Upper Area could accommodate any of the following scenarios: Capacity Scenarios Number of Passenger Vehicle Parking Number of Horse Trailer Parking Number of Shuttle Bus Parking Scenario 1 65 0 0 Scenario 2 45 4 0 Scenario 3 45 0 4 The Lower Area could accommodate any of the following scenarios: Capacity Scenarios Number of Passenger Vehicle Parking Number of Horse Trailer Parking Number of Shuttle Bus Parking Scenario 1 15 0 0 Scenario 2 0 2 0 Scenario 3 0 0 2 R-23-38 Page 8 Staff seeks the Committee’s direction on the scenarios to develop final parking program alternatives, which may be a combination of the scenarios listed above and may include other parking elements. For example, one possible combination of these scenarios that maximizes all three uses is to provide 45 passenger vehicles, 2 horse trailer spaces and 2 shuttle spaces in the Upper Area; and 15 passenger vehicle spaces in the Lower Area. The above scenarios are only to demonstrate maximum available space at each expansion area and are not the only parking alternatives that should be considered for the Project. In addition, the Project will consider the following Transportation Demand Management strategies (TDMs) recommended in the Purisima Multimodal Access Study that the Board approved on November 9, 2022. The expectation is that many of these strategies will be suitable for the site and be incorporated into the design and long-term management of the parking area: Highest priority TDMs • Peak period parking reservations/priority parking • Bicycle parking and facilities (including bicycle repair stations) • Temporarily redesignate spaces on specific days/times to best meet demands o May include designating special parking areas temporarily for carpool, equestrian, shuttle pick-up/drop-off, or other uses • Real-time parking lot occupancy sensors and signage • Electric Vehicle (EV) charging infrastructure Lower priority TDMs • Vehicle wayfinding signage • Clearly identify permitted on-street / shoulder parking • Accommodate future shuttle / transit systems FISCAL IMPACT The Fiscal Year 2022-23 budget includes $95,000, which covers consultant, site engineering, and geotechnical costs through the end of the fiscal year. The Project received $114,000 in grant funding from the SFPUC for completion of the feasibility study, which was authorized by the Board in 2020 (Res. 20-32). This project is not currently funded by Measure AA as it is still within a feasibility stage. However, implementation of capital improvements may be eligible for Measure AA reimbursements. PRIOR BOARD AND COMMITTEE REVIEW • September 29, 2020: The Legislative, Funding and Public Affairs Committee (LFPAC) reviewed the partnership agreement and recommended the Board adopt a resolution authorizing the General Manager to accept $114,000 in grant funding from the SFPUC for the Project. o Board Report (R-20-101) o Minutes R-23-38 Page 9 • October 28, 2020: The Board adopted a resolution authorizing the General Manager to accept grant funding for the Project. o Board Report (Res. 20-32) o Minutes PUBLIC NOTICE Public notice was provided as required by the Brown Act. In addition, public notices were sent to Preserve neighbors along Highway 35 and interested parties of the Preserve and hiking, biking, equestrian, accessibility, and regional trails interested parties’ lists. CEQA COMPLIANCE The Highway 35 Multi-use Trail Crossing and Parking Feasibility Study is not a project subject to the California Environmental Quality Act (CEQA). Environmental review is anticipated to occur in a future fiscal year, pending Board selection of a project design alternative as the CEQA project description.

Parking Expansion 2 1.0 Project Background and Goals 1.1 Project Background The District is conducting a feasibility study to identify a trail crossing location from the Purisima Creek Redwoods (Purisima, Preserve) North Ridge parking area across Skyline Boulevard (Highway 35) to connect existing segments of the Bay Area Ridge Trail within Purisima, west of Highway 35, to a new segment of the Bay Area Ridge Trail planned on the east side of Highway 35 (Ridge Trail Extension). The feasibility study will also analyze the potential expansion of the North Ridge parking area to serve visitors to both the existing trailhead and to the proposed Ridge Trail Extension. The Highway 35 Multi- use Trail Crossing and Parking Study (Project) is a partnership between the District, San Francisco Public Utilities Commission (SFPUC), Bay Area Ridge Trail Council (Ridge Trail Council), and Peninsula Open Space Trust (POST). The intent of the Project is to enhance regional connectivity through a multi-use highway crossing allowing access to trails on both sides of Highway 35 and to identify ways to reconfigure and increase parking capacity of the North Ridge parking area. The North Ridge parking area and trailhead is the northern-most entrance to Purisima, located on the west side of Highway 35, approximately midway between Highway 92 to the north and Highway 84 to the south (see Figure 1). To the east of Highway 35 are SFPUC’s watershed lands, where SFPUC is planning to construct a new segment of the Bay Area Ridge Trail (Ridge Trail Extension). The Ridge Trail Extension would run approximately six miles south from Highway 92 on SFPUC watershed lands and terminate near the boundary of the Golden Gate National Recreation Area (GGNRA) Phleger Estate property. As part of the Ridge Trail Extension project, SFPUC will construct a new parking area at the north end of the new trail, just south of the intersection of Highways 92 and 35. The Purisima North Ridge parking area will be the nearest parking location to the south end of the six-mile Ridge Trail Extension and is likely to attract future trail users looking to access the new trail segment. Lack of a nearby highway crossing location from the North Ridge parking area to the east side of Highway 35 may potentially create safety concerns for users of the Ridge Trail Extension attempting to cross Highway 35 from the North Ridge parking area. In addition, an increase in visitors to the North Ridge parking area may exacerbate parking congestion in a lot that is prone to exceeding capacity on weekends from current visitors to Purisima. To address these potential impacts from the Ridge Trail Extension, the District and its project partners (Ridge Trail Council, POST, and SFPUC) identified the need to study the feasibility of a crossing location on Highway 35 and an expansion of the existing North Ridge parking area. This Project will analyze expanded parking and multimodal access options at the North Ridge parking area, identify a multi-use trail crossing area on Highway 35, and an alignment of a spur trail to connect the Highway 35 crossing location directly to the SFPUC’s planned Ridge Trail Extension. The North Ridge trailhead provides access to an existing segment of the Bay Area Ridge Trail within Purisima and the multi-use trail crossing and spur trail would connect it with the planned Ridge Trail Extension. Providing connections between Purisima and the Ridge Trail Extension will contribute an important regional connection for multiple trail users, including hikers, bicyclists, and equestrians. The Project is occurring in parallel with two other planning studies at Purisima to improve public access and complete regional trail connections. In 2022, District staff completed the Purisima Creek Multimodal ATTACHMENT 1 Highway 35 Multi-use Trail Crossing and Parking Expansion 3 Access Study, which evaluated existing visitation at Purisima and developed a plan to address parking and traffic congestion issues, increase greener modes of transportation, and better manage visitation at the preserve. The Multimodal Access Study recommends a series of Transportation Demand Management strategies (TDMs) to be implemented preserve-wide as well as some strategies specific to the North Ridge parking area, in order of priority. Planning for the Purisima-to-the-Sea Trail and Parking Area project is also underway, which is studying the addition of five miles of new trail within Purisima to link the California Coastal Trail to the Bay Area Ridge Trail. The project also includes planning of a new parking area to improve capacity for coastal access to Purisima. The District is supporting the implementation of a regional trail network through the efforts of these projects and through ongoing partnerships to provide access to important trail connections. Purisima is located at a significant junction for regional trails that will provide north-south corridors along the Bay Area Ridge Trail, as well as east-west corridors through the Bay to Sea Trail with the Purisima-to-the-Sea component. These regional trail networks not only provide opportunities to connect trail users to a variety of open spaces, but also to understand the importance of regional conservation efforts and contiguous open spaces for maintaining natural ecosystems. 1.2 Project Goa ls The intent of the Project is to enhance regional connectivity through a multi-use highway crossing allowing access to trails on both sides of Highway 35 and to identify ways to reconfigure and increase parking capacity of the North Ridge parking area. Project goals and strategies have been identified to guide the development of Project elements and evaluate Project success. Goal 1: Support the implementation of the regional Bay Area Ridge Trail. Strategies: • Identify a multi-use trail crossing and trail spur location to connect the SFPUC’s new segment of the Bay Area Ridge Trail to the Preserve and the existing Ridge Trail segment within the Preserve. • Maximize safety and minimize neighbor impacts when evaluating multi-use trail crossing locations and infrastructure. • Develop the multi-use trail crossing and spur trail to accommodate low-intensity recreational use by hikers, bicyclists and equestrians, consistent with Bay Area Ridge Trail corridor goals. • Collaborate with partner agencies to complete the planning, design and implementation of the multi-use trail crossing and spur trail. Goal 2: Improve public access and visitor experience at Purisima’s North Ridge trailhead using ecologically sensitive design, construction practices, and long-term maintenance and management. Strategies: • Add parking capacity through reconfiguration of existing parking spaces and expansion of the North Ridge Parking Area. ATTACHMENT 1 Highway 35 Multi-use Trail Crossing and Parking Expansion 4 • Improve the existing trailhead amenities, such as replacing the existing restroom with a new ADA compliant vault restroom, replacing dated signboards with current standard design, and adding bicycle parking. • Incorporate Transportation Demand Management Strategies consistent with the Board- approved Purisima Multimodal Access Study recommendations. • Design recreational amenities to protect the scenic corridor. • Maximize safety and minimize neighbor impacts when evaluating the multi-use trail crossing, parking enhancements and vehicle circulation. • Maintain routine patrols and maintenance and use adaptive management to address unforeseen issues that arise from increased visitation to the North Ridge trailhead. 2.0 Existing Conditions The Project site includes an area west of Highway 35 within Purisima Creek Redwoods Open Space Preserve, comprised of the existing North Ridge parking area and adjacent open areas west of the parking area. The site of the existing North Ridge parking area was purchased as an addition to the Preserve in 1983 (R-83-05). Prior to this land purchase, the District had acquired a public easement over the area that allowed for vehicular access and parking as part of the original Whittemore Gulch purchase, the first acquisition to form what is now called Purisima Creek Redwoods Open Space Preserve (R-82-30). The site was identified as having the potential to allow for a parking area adjacent to Skyline Boulevard to provide Preserve access. In 1988, with grant funds from the State of California, the North Ridge parking area was enlarged to the current capacity for passenger vehicles and horse trailers and trailhead improvements were completed. According to a review of the Use and Management Plan for the Preserve in 1989, public use of the Preserve increased sharply with the new public access improvements and the available parking associated with the three Preserve trailheads (North Ridge, Purisima Creek/Higgins Road, and Redwood) reached capacity on weekends (R-89-20). The boundaries of the existing parking area and proposed parking expansion areas follow the Purisima property boundary with Fisher Investments to the north and Highway 35 right of way to the east. The employee residence defines the west boundary of the lower parking expansion area, and the southwest boundaries of the project site are defined by dense forest and other vegetation that signal the start of the preserve (see Figure 2). The Project site also includes the Caltrans Highway 35 right of way and approximately four acres of SFPUC Watershed lands east of Highway 35 for the spur trail study area. 2.1 Natural Resources North Ridge trailhead is located along the upper ridge of a watershed that flows west into the preserve and into Purisima Creek. Due to the location of the trailhead on a ridge bordering two watersheds, many aquatic features such as creeks, rivers, and wetlands do not occur near the trailhead, but further west into the preserve where the topography slopes toward the coast. 2.2 Public Access The North Ridge parking area and trailhead is the northern most entry point into Purisima Creek Redwoods Open Space Preserve and is located along Highway 35, approximately 4.5 miles south of its intersection with Highway 92 (Figure 3). From the North Ridge trailhead, visitors can access the 5,400- acre Purisima preserve located on the western slopes of the Santa Cruz Mountains. Purisima offers ATTACHMENT 1 Highway 35 Multi-use Trail Crossing and Parking Expansion 5 twenty-two miles of public trails with access for hikers, bicyclists, and equestrians as well as views of the coast from various trails along the ridgelines that slope toward the coast from east to west. The parking area is adjacent to the west side of Highway 35 with a vegetated barrier between the parking area and the highway right-of-way. The gravel parking area can accommodate perpendicular parking for 41 standard vehicle spaces and two ADA spaces. The parking area is unstriped and does not delineate parking stalls, except for the two ADA spaces that are identified by ADA parking signs and a blue curb. Wheel stops line the west and east sides of the parking area and help to define the boundaries of the existing lot. While the North Ridge parking area does not include designated equestrian parking spaces, approximately two equestrian trailers can be accommodated for parallel parking along the split-rail fencing on the northwest side of the parking lot. The North Ridge trailhead includes standard trailhead amenities such as an equestrian hitching post, map and sign boards, a boot brush, and a single-stall vault restroom. The vault restroom, installed in 1999, is in deteriorating condition and requires improvements and an accessible path to meet ADA accessibility standards. The North Ridge parking area is accessible by a one-way entrance on the south end of the parking area and a one-way exit at the north end of the parking area, which circulate traffic in a single direction through the parking area from south to north. There are no entry or exit signs visible from Highway 35, aside from a “do not enter” sign at the north driveway that indicates that it is an exit only. Within the parking area, an exit sign is posted near the north driveway and a “not an exit” sign is posted near the south driveway. A preserve sign for Purisima Creek Redwoods is located next to the North Ridge entrance and is visible from Highway 35. Of the four parking areas available for visitors to Purisima, the North Ridge parking area can accommodate the largest number of on-site vehicle parking. All four parking areas frequently exceed capacity on the weekends, during peak visitation, and visitors often use informal, roadside parking when the lots are full. The Purisima Multimodal Access Study (2022) found that during the peak summer months, the North Ridge parking area alone averaged between 225 to 525 vehicles and 500 to 1,225 pedestrians per day1, despite its maximum 41-car capacity. 2.3 Local and Regional Connectivity Highway 35 provides key access points not only to Purisima, but also to the greater Skyline region, including direct access to seven other preserves within the District and many other open spaces that together act as a protected, regional greenbelt throughout the mid-peninsula. Among the many trails and open spaces accessible from Highway 35 are a series of existing and planned regional trails that provide connections throughout the Bay Area. Purisima will provide important trail connections for many regional trails, including the Bay Area Ridge Trail and the planned Bay to Sea trail, lead by POST, which will be an approximately 40-mile regional trail that is envisioned to connect communities from the San Francisco Bay to the Pacific Ocean. A key component of the Bay to Sea trail will be the development of the District’s Purisima-to-the-Sea trail, which will create a five-mile trail connection through Purisima to the California Coastal Trail along Highway 1. Purisima also contains existing segments of the Bay Area Ridge Trail, of which these segments contribute to over 400 miles (and counting) of existing multi-use trail that follow the ridgelines encircling the San Francisco Bay. The alignment of the Ridge Trail 1 Purisima Creek Multimodal Access and Transportation Demand Management Study. Attachment 1, page 10. ATTACHMENT 1 Highway 35 Multi-use Trail Crossing and Parking Expansion 6 Extension on SFPUC Watershed lands poses an opportunity to connect Purisima and its Bay Area Ridge Trail segment to the new trail extension through the Project’s multi-use trail crossing on Highway 35. 2.4 Cultural Resources The Project area is within a region that was historically occupied by tribes of the Ramaytush Ohlone people. Ohlone territory spanned from areas north of the San Francisco Bay down the coast as far as Carmel Valley, and inland to the coast range. San Mateo County is home to numerous historic Ohlone sites and villages, whose boundaries were typically defined by topographic features such as rivers, watersheds, and ridgelines. The nearest known cultural site of the Ramaytush Ohlone is a well-known and historically significant village site located at what is now the private Filoli Estate, approximately two miles northeast of the Project area on the eastern slope of the Santa Cruz Mountains. 2.5 Aesthetics The North Ridge trailhead is surrounded by a rural, forested setting, primarily comprised of redwood forest with some annual grassland and Monterey cypress woodland. The area is also sparsely populated with single family residences and businesses along the Highway 35 corridor. The North Ridge trailhead is accessible from Highway 35, a rural, two-lane highway providing north and south-bound travel along the ridgeline of the Santa Cruz Mountains. The California Department of Transportation (Caltrans) has designated Highway 35 as a scenic highway, which is meant to preserve the visual character of highways and manage new development to preserve the scenic and natural features visible from the highways. The stretch of Highway 35 in the vicinity of the North Ridge trailhead is lined with heavy vegetation that contributes to its scenic beauty, but can also make roadway visibility challenging at high speeds. 2.6 Operations and Maintenance Adjacent to the west boundary of the existing parking lot is an approximately 0.3-acre (13,000 square foot) open, flat area (Upper area) that is vacant aside from the hitching post. This Upper area is used as a helicopter landing zone by the California Department of Forestry and Fire Protection (CalFire) for emergency response. Further west of the Upper area, moving into the preserve, the land slopes down to another open, flat area (approximately 1.2 acres or 52,000 square feet) where a employee residence and separated garage are located (Lower area). This Lower area previously hosted an experimental fog collector, a device installed in 2016 to conduct initial studies of moisture collection from fog that occurs over the Santa Cruz mountains. The fog collector was removed in December of 2022 after the data collection ended in 2018 and the device was left idle for many years. The slope separating the two open areas west of the North Ridge parking area is also covered with dense vegetation, which provides visual and physical separation between the trailhead and the employee residence. The employee residence is accessed by a gated, gravel driveway along the north boundary of the preserve that connects the property to the North Ridge parking area. The adjacent property to the north of the North Ridge parking area is owned and occupied by a private company, Fisher Investments. Their property is highly developed with offices and other support buildings as well as a parking area accessible from Highway 35. To the east of the North Ridge parking area and of Highway 35 are SFPUC watershed lands, which are undeveloped and primarily consist of dense redwood forest. Adjacent properties to the south of the North Ridge trailhead are private, single- family homes. The closest private driveway is 400 feet south of the entry driveway to the North Ridge trailhead. ATTACHMENT 1 Highway 35 Multi-use Trail Crossing and Parking Expansion 7 The posted speed limit is 50 mph at the North Ridge trailhead, however, many nearby residents and frequent preserve visitors have provided public comments that vehicles often go at much higher speeds. The District is aware of safety concerns regarding the speed of vehicles travelling along Highway 35 and the feasibility study aims to identify potential safety concerns related to the Project. 3.0 Technical Studies District staff contracted with professional consulting firms to complete various technical studies to analyze the biological, cultural, traffic, and topographic characteristics of the Project area (including both the Upper and Lower parking expansion areas). The methodology, key findings, and recommendations from these studies are summarized below. 3.1 Biological Resources Survey and Phytophthora Risk Assessment In June, 2022, AECOM conducted a thorough Biological Resources Survey to identify any existing or potential biological resources within the proposed Project area. In particular, the survey was conducted to identify all San Francisco dusky-footed woodrat (SFDFW) middens present within the project area, any substantial or permanent nesting bird resources (e.g. suitable nesting trees) in the area, any aquatic features including jurisdictional wetlands or other waters, the presence of any bat maternity roosts within the onsite residence, and the suitability of the Project site for special-status wildlife habitat. A daytime biological survey analyzed an area consisting of the Project site, traffic survey area, spur trail study area, and included three buffer areas of up to 1,000 feet for nesting birds. A bat emergence survey was also conducted during the evening to monitor any bat activity near the employee residence and garage. The surveys found one active SFDFW midden at a distance approximately 250 feet from the project area, which is unlikely to be affected by the Project. No active raptor, accipiter, or passerine bird nests or nesting platforms were found in the vicinity of the Project site; however, a Monterey cypress tree being used as an acorn woodpecker granary was found in the Spur Trail study area. The survey found no evidence of aquatic resources or jurisdictional wetlands and special status species within the Project area, nor was there evidence of the presence of bat maternity roosts within the onsite employee residence or garage. Due to the project site’s proximity to Huddart County Park which is a designated critical habitat for the endangered marbled murrelet, District staff conducted a site assessment for marbled murrelet and consulted with California Department of Fish and Wildlife (CDFW) about the potential need for special species protections. However, based on results of the site assessment and discussions with CDFW, both the District and CDFW staff confirmed that no suitable murrelet habitat within the project area and within the project vicinity, therefore the project will have zero species impacts. Noise and visual disturbance avoidance measures will likely not be necessary. In February 2023, AECOM prepared a Phytophthora Risk Assessment in order to identify the modality of soil pathogen infection and to provide specific mitigation and best management practices to minimize the introduction or spread of Phytophthora species at the site. Analysis found that the project area has ATTACHMENT 1 Highway 35 Multi-use Trail Crossing and Parking Expansion 8 relatively low levels of contamination risk; however, areas east of Hwy 35 are highly receptive to contamination and are considered sensitive sites. 3.2 Traffic Survey TJKM Transportation Consultants (TJKM) evaluated the sight distance conditions for the two existing parking area driveways and the feasibility/design of a new on-grade trail crossing on Highway 35. TJKM performed a Sight Distance analysis using standards in “Highway Design Manual”, 2020 7th Edition by the California Department of Transportation, a policy on Geometric Design of Highways and Street, 2018 7th Edition, from the American Association of State Highway and Transportation Officials (AASHTO) and the California Manual on Uniform Traffic Control Devices (CA-MUTCD). In April 2022, TJKM measured vehicle speeds in the vicinity of the North Ridge parking area to determine the project design speed. The project design speed is the 85th percentile of actual speeds measured on the roadway; it is used to determine if adequate sight distance is available for vehicles exiting the existing driveways, and if northbound and southbound vehicles on Highway 35 have adequate stopping sight distance for the new on-grade trail crossing. Although the posted speed limit is 50 mph, the design speed measured on the road was 51.7 mph northbound and 51.0 mph southbound. TJKM rounded these findings up to 55 mph as the final design speed used in the feasibility analysis. TJKM also reviewed five years of traffic collision data within the vicinity of the project site to inform the final recommendations. There were no reported incidents directly in front of the parking area to prompt additional recommendations. The traffic collision data can be found as an appendix to the traffic report. Based on the available information, TJKM concluded that there is a feasible on-grade trail crossing location immediately adjacent to the existing exit driveway. TJKM recommended improvements within the right-of-way to preserve site distances and enhance visibility of the trail crossing (see Figure 4). Furthermore, TJKM concluded that the existing driveway configuration is the most favorable for ingress and egress. TJKM has sought concurrence with the California Department of Transportation (Caltrans) on their findings and recommendations. Caltrans reviewed the findings and requested additional information in the final report, which was provided by TJKM. Caltrans does not have any further comments at this time. Additional coordination with Caltrans will be required for future encroachment permits, which would occur after a Board-approved alternative is selected and analyzed as part of the CEQA environmental review process. Refer to roadway trail crossing graphics for more details (Figure 4). 3.3 Cultural and Historic Resources Survey Cogstone Resource Management, Inc. conducted cultural and historic resource surveys in the fall and winter of 2022 to determine if any cultural or historic resources were present within the Project area that may be affected by implementation of the Project. Cogstone conducted background research involving a search for archaeological and historical records at the Northwest Information Center (NWIC) as well as a request for a Sacred Lands File (SLF) search from the Native American Heritage Commission (NAHC). Cogstone also conducted a pedestrian survey of the Project area to determine whether any archaeological resources were present. No archaeological resources were observed during the survey and the background research did not find any previously recorded cultural or historical resources located within the Project area. The boundary of one historic resource, the Filoli Estate, was located within the half mile search radius, but is outside of the Project area and is unlikely to be affected by the proposed Project. The SLF search identified one tribal band and the NAHC recommended they be contacted for information on any tribal cultural resources in the vicinity of the Project. The District will ATTACHMENT 1 Highway 35 Multi-use Trail Crossing and Parking Expansion 9 will contact the tribe directly once preliminary concept plans are available and again when a design alternative is selected and the Project proceeds to the environmental review phase, as required by the California Environmental Quality Act (CEQA) and in accordance with Assembly Bill (AB) 52 consultations. No archaeological monitoring is anticipated due to the geological age of the soils as well as the absence of any known cultural resources within the Project area. Cogstone also conducted an Historic Resources Evaluation for the nearby onsite employee residence that was built over 50 years ago (circa 1948) given its proximity to the parking area. The residence includes Ranch style architectural elements such as a low pitch roof with a wide eave overhang. The entire exterior of the single-family residence was photographed and recorded on the Department of Parks and Recreation 523 (DPR 523) forms. Due to a lack of significance and notable architectural alteration, the residence was not found eligible for listing at the local, state, or national level. No further evaluation is recommended. No changes are proposed for this residence, which would remain in place as part of the Project and continued to be used as an employee residence to maintain onsite presence and vigilance of the property. 4.0 Opportunities and Constraints This section describes the opportunities and constraints for the Project site, which are related to important attributes of the site and require consideration for Project program development. Opportunities and constraints are categorized by topic area (such as Natural Resources or Public Access) and some attributes may be listed as both an opportunity and a constraint based on their relationship to the Project goals. In addition, several policies and best management practices (BMPs) that may be relevant to the Project are listed below. Potential applicable policies, guidelines, or regulations: • Caltrans Highway Design Manual • District Best Management Practices • District Good Neighbor Policy • District Resource Management Policies • Purisima Multimodal Access Study • San Mateo County Active Transportation Plan • San Mateo County General Plan. 4.22 Scenic Corridors. Protect and enhance the visual quality of scenic corridors by managing the location and appearance of structural development. • San Mateo County General Plan. 4.24 Rural Development Design Concept. Regulate the location and siting of structures in rural areas to encourage positive visual quality in relation to the scenic character of the natural landscape. • San Mateo County Heritage/Significant Tree Ordinance • San Mateo County Trails Plan • San Mateo Water Pollution Prevention Program *Relevant policies, guidelines or regulations are shown with corresponding opportunities or constraints and labeled with and asterisk. ATTACHMENT 1 Highway 35 Multi-use Trail Crossing and Parking Expansion 10 4.1 Natural Resources Attribute Opportunities & Constraints Discussion Biological Resources O The biological survey conducted for the Project site did not uncover any special-status wildlife species, nesting birds or raptors, aquatic resources, roosting bats, or other sensitive biological resources within the Project area. A Dusky-Footed Woodrat midden is present about 250 feet from the Project area, which is well beyond the minimum avoidance buffer of 3-10 feet established by the District. It is unlikely that midden would be affected by the Project at this distance. It is unlikely that marbled murrelet protections will be required during construction. Construction activities should avoid direct impacts to trees within the spur trail study area during bird nesting season (between March 15 and August 30). * District wildlife BMPs: nesting bird surveys, SF dusky-footed woodrat midden avoidance buffer, marbled murrelet AMMs Biological Resources C There is dense vegetation along the east side of Highway 35 (on SFPUC Watershed lands), which may affect the spur trail alignment as well as the line of sight for the multi-use crossing. Some vegetation may need to be removed and/or trimmed back to improve line of sight for the crossing as well as develop the spur trail connection to the Ridge Trail Extension. *San Mateo County Heritage/Significant Tree Ordinance Hydrology C Drainage from the existing parking area and trailhead flows west, into the preserve, while drainage on the east side of Highway 35 flows east, contributing to the SFPUC watershed. An existing drainage culvert is located just south of the North Ridge trailhead and parking entrance. Drainage from the site may be affected by construction activities related to parking expansion as well as an increase in impervious surfaces. Potential runoff from an expanded parking area will need to be evaluated to ensure there will be no impacts to water quality and buffers implemented where/if necessary. *San Mateo Water Pollution Prevention Program Pathogens O/C The Phytophthora risk assessment determined that the project site has relatively low levels of pathogen contamination west of Highway 35. However, movement of Phytophthora pathogens may also migrate from the Project area and construction activities (e.g. reseeding) to SFPUC property east of Highway 35 and some sensitive areas will require particular protection from infection. *Phytophthora Risk Assessment BMPs and AMMs ATTACHMENT 1 Highway 35 Multi-use Trail Crossing and Parking Expansion 11 4.2 Public Access Attribute Opportunities & Constraints Discussion Parking Area O The existing North Ridge parking area and trailhead are frequently visited and familiar to visitors of Purisima, as it is currently the largest parking area available for the preserve. Expansion of the parking area coupled with multimodal access strategies are expected to significantly alleviate parking demands and potentially meet anticipated parking needs at this trailhead. The Project will maintain the existing vegetated buffer and berm between the parking lot and Highway 35 to minimize visibility of the parking area from the highway. The separate driveway for entrance and exit will also be preserved to better accommodate larger vehicles such as shuttle buses, emergency vehicles, and equestrian trailers. This will save space by not requiring a turn-around area. Minor improvements to signage may be implemented to better identify the entry and exit to vehicles travelling along Highway 35. Parking Capacity C Although expansion of the parking area would add much needed parking at the North Ridge trailhead, the available expansion areas are limited in size. Future expansion will likely not fulfill the maximum parking demand at peak visitation hours and TDM strategies should be considered to manage parking. *Good Neighbor Policy *Purisima Mulitmodal Access Study Trail Crossing Location O Based on the traffic study conducted at the North Ridge trailhead, an adequate line of sight was identified that would allow for a safer crossing location just south of the exit driveway. The adequate line of sight indicates that vehicles traveling north and south bound along Highway 35 will have enough warning, visibility, and space to yield to trail users crossing at the recommended location. The traffic study also recommended the use of crossing signage that is consistent with many other highway crossing locations along Highway 35 and would be familiar to trail users and vehicles approaching the crossing. *Caltrans Highway Design Manual Policy 405.1 *SMC Active Transportation Trail Crossing Safety C During the stakeholder engagement process neighbors expressed concern over current excessive vehicle speeds along Highway 35 that are perceived to be much higher than the posted speed limit. While the traffic study analysis used current traffic data and accounted for greater vehicle speeds along Highway 35 in its recommendation of the highway crossing location, further consultation with Caltrans is required to determine the final crossing design and signage that would be appropriate for the recommended crossing location. Parking O On the west side of Highway 35, the existing parking area and adjacent upper expansion area are generally flat with a very gradual ATTACHMENT 1 Highway 35 Multi-use Trail Crossing and Parking Expansion 12 slope to the west, into the preserve. Adjacent to this area, a steep, vegetated slope separates the upper parking expansion area from the lower expansion area and employee residence. The terrain levels out again at the lower expansion area and residence with just a gradual slope to the southwest. The existing topography will influence the parking capacity for both the upper and lower parking expansion areas and neither expansion area will require significant grading. During the stakeholder engagement process, interest was expressed in adding designated equestrian parking at the North Ridge trailhead. Although equestrian parking is currently permitted at North Ridge, equestrians must share the space with standard vehicle parking and there is rarely enough available space to park equestrian trailers during peak visitation hours. Reconfiguring and expanding the parking area will provide an opportunity to address public interest in adding designated equestrian parking to the North Ridge parking area. Parking C The steep, vegetated slope creates a barrier between the upper parking expansion area and the lower expansion area and employee residence. This slope limits the area that can be used for on-site parking expansion as well as internal circulation if the lower expansion area is utilized. The addition of designated equestrian parking would mean reducing the number of additional standard vehicle parking that could be accommodated onsite. Although feedback from the stakeholder engagement process showed interest in designated equestrian parking, it’s unclear how many spaces are required to meet the demand for equestrian parking and whether this should be prioritized over the addition of standard vehicle parking, which is in high demand at this location. Proximity to Adjacent Properties O There are limited adjacent properties and driveways in the vicinity of the Project site that could be impacted by an increase in visitation to the North Ridge parking area. The Fisher Investments property, adjacent to the north boundary of the North Ridge parking area, has an opposite visitation schedule from visitors to North Ridge where most Fisher Investments employees are working on site during the weekdays, while Purisima has peak visitation on weekends. *Good Neighbor Policy Proximity to Adjacent Properties C The lower parking expansion area is adjacent to the existing employee residence. Use of the lower parking expansion area for additional visitor parking may require a buffer from the residence for privacy and to maintain District operational access to and from the residence. Although the Fisher Investments property is busiest on weekdays when visitation to Purisima is lower, the Ridge Trail Extension may increase weekday visitation that could contribute to more traffic congestion in the vicinity of the private property. *Good Neighbor Policy ATTACHMENT 1 Highway 35 Multi-use Trail Crossing and Parking Expansion 13 4.3 Local and Regional Connectivity Attribute Opportunities & Constraints Discussion Trail Crossing Location O Existing segments of the Bay Area Ridge Trail within Purisima can be accessed from the North Ridge trailhead, which makes a multi-use trail crossing at Highway 35 from the planned Ridge Trail Extension to the North Ridge trailhead a natural and direct connection point. *San Mateo County Trails Plan 4.4 Cultural and Historic Resources Attribute Opportunities & Constraints Discussion Cultural Resources O The cultural resources survey conducted for the Project site did not identify any previously recorded cultural resources within the Project area and no archaeological resources were encountered during the pedestrian survey. A Sacred Lands File search identified one Native American Tribe that will be consulted when preliminary concept plans are available and during the planning and CEQA environmental review process to obtain more information about any potential cultural resources within the Project site. Due to the results of the pedestrian survey, background research, and soil analysis, archaeological monitoring is not recommended during development of the Project. *District Cultural Resources Policies Historic Resources O The historic resources evaluation thoroughly documented and analyzed the site’s existing employee residence to determine if it is historically significant. Despite the age of residence, originally constructed sometime between 1941 and 1948, this building is not recommended as eligible for listing at the local, state, or national level due to lack of significance and the notable architectural alterations made to the residence since it was originally built. *District Cultural Resources Policies 4.5 Aesthetics Attribute Opportunities & Constraints Discussion Caltrans Scenic Highway Designation O Caltrans designates portions of Highway 35 as a state scenic highway, including the portion of Highway 35 adjacent to the Project site. Caltrans and San Mateo County have developed policies that regulate development along scenic corridors and provide guidance for other ATTACHMENT 1 Highway 35 Multi-use Trail Crossing and Parking Expansion 14 visual resources. The existing North Ridge parking area is adjacent to Highway 35 and partially visible from the highway. A barrier of redwood trees along the east boundary of the parking lot separates the existing parking area from the highway right-of-way and provides a natural visual barrier, which will remain regardless of the final parking area program. In addition, the proposed lower parking expansion area is set back from the roadway and is lower in elevation as compared to the existing parking area, which will help to reduce visibility of the expanded parking area from the highway. The Project proposes to maintain the existing entry and exit driveways to the parking area along Highway 35 to minimize the Project’s visibility from the scenic highway. * San Mateo County General Plan. 4.22 Scenic Corridors California Streets and Highways Code Division 1, Chapter 2, Article 2.5 Caltrans Scenic Highway Designation C Although the Project will direct new development to areas away from Highway 35, there is potential for changes to be visible from the highway, including the upper parking expansion area and the replacement vault restroom, which would be relocated to a more central location to address ADA barriers. In addition, the Project will require a crossing sign and two crossing warning signs to be installed along Highway 35 to identify the multi-use trail crossing location. While these traffic features will be minimal, they are meant to be highly visible to vehicles travelling on Highway 35 to promote safer crossing. Vegetation clearing along Highway 35 right-of-way will also occur, both to support the traffic study recommendations for improving line of sight to the multi-use trail crossing as part of the Project and separately through Fire Safe San Mateo County to support fuel reduction efforts for wildfire prevention. *San Mateo County General Plan. 4.24 Rural Development Design Concept. California Streets and Highways Code Division 1, Chapter 2, Article 2.5 4.6 Operations and Maintenance Attribute Opportunities & Constraints Discussion Utilities and Services O Above-ground power lines run along Highway 35 adjacent to the Project site and underground electric lines currently serve the employee residence, garage, and the existing parking area entry and exit gates. A water main line also runs beneath Highway 35, including a water distribution line that serves the employee residence. Cellular service is also available at the existing North Ridge parking area. Utilities and Services C Sewer service is not available at the employee residence nor at the North Ridge trailhead. The trailhead provides a vault restroom for public use. Relocating the vault restroom would be a challenge due to ATTACHMENT 1 Highway 35 Multi-use Trail Crossing and Parking Expansion 15 the existing topography and vegetation near the trailhead that limits alternative locations. The vault restroom will be replaced with an ADA-accessible model. Vault restrooms, as opposed to plumbed restrooms, are only permissible on a case-by-case basis through an exemption with the County of San Mateo. Preliminary inspection by District staff indicates that the site meets the criteria to allow the exemption. CalFire Landing Zone C District staff have reached out to the agencies and organizations that may utilize the landing zone at the upper expansion area, including CalFire, San Mateo County Fire, and the Kings Mountain Volunteer Fire Department. These organizations are aware of the Project and have not requested further coordination at this time. In addition, there are other landing zones located in the vicinity of the Project area that are currently used by these organizations. These nearby alternative landing zone locations include private properties on Cyprus Ridge Road, less than a mile north of the Project site, and Tunitas Creek Road, approximately two miles south of the Project site. The nearest alternative landing zone on District lands is located at El Corte de Madera Creek Preserve, approximately five miles south of the Project site. Should a Project alternative be selected for CEQA review that would change the use of the landing zone, District staff will engage in additional coordination with these agencies at that time to confirm the site can be formally retired. 5.0 Public and Stakeholder Engagement From 2021 to 2022, the District engaged with stakeholder groups and partners as part of the Project focused meetings and at meetings that included the Purisima-to-the-Sea project and the Purisima Multimodal Access Study. These engagement activities were used to gather initial feedback on existing challenges at the North Ridge parking area and any desired amenities that should be considered for this parking area. Feedback received includes the following 2: Theme/Topic General Feedback/Comments Traffic and Safety • Concerns related to providing a safe pedestrian roadway crossing due to current vehicle speeds on Highway 35 • Neighbors would like to see roadway striping and advanced warning beacon for trail crossing • Concerns related to roadside parking that create potentially unsafe roadway conditions for pedestrians and vehicles • Suggestion to modify parking area entrance to allow vehicles to turn into the parking area quickly 2 This feedback has been received in addition to previous feedback that was presented to the PNR Committee and the Board as part of the Purisima Multimodal Access engagement on August 2nd, 2022 (see attachment 5) . ATTACHMENT 1 Highway 35 Multi-use Trail Crossing and Parking Expansion 16 • Suggestion to review historic traffic accident data in the vicinity of North Ridge to better understand safety issues • Concerns related to foggy conditions on Highway 35 that could limit visibility Parking and Visitor Capacity • Allowing E-bikes within the Preserve may reduce parking demand • Request for better equestrian parking and access at this trailhead • Better/clearer roadway parking signage can discourage parking along the roadway that impacts neighboring properties Amenities • Support for the proposed trailhead amenities • Suggestion to include emergency response information on trailhead signage General • General support for the Project if concerns are addressed • New regional trail connection may result in additional traffic and trash • Concerns regarding relocating the CalFire helicopter landing zone and how this would impact fire response 5.1 Partner and Agency Meetings On October 19th, 2022, District staff made a presentation at a monthly meeting of the Peninsula Trails Team, a working group made up of regional trails partners and land managers, including representatives from POST, SFPUC, Ridge Trail Council, California Coastal Conservancy, County of San Mateo, National Parks Service, Golden Gate National Recreation Area, and the District. Following the presentation of the Project scope, updated schedule, and the results of the completed technical studies, the group discussed regional implications for the new trail connection as well as the potential timing for future planning and CEQA environmental review. 5.2 Neighborhood Meetings District staff met with representatives from local organizations including members of the Kings Mountain Association, a neighborhood association, and the facilities manager of Fisher Investments, the neighboring property to the north of the Project site. District staff presented the Project to the Kings Mountain Association in March and November of 2022 and engaged in group discussions. District staff also provided a presentation to the facilities manager of Fisher Investments on November 9th, 2022 to notify them of the Project, answer questions, and receive initial feedback. 5.3 Stakeholder Group Meetings District staff invited individuals who were familiar with Purisima and other District preserves to participate in focused virtual stakeholder meetings held on November 15th and 17th, 2022. The individuals invited to the stakeholder meetings were identified from their previous participation in public engagement activities with the District and represented a range of user groups, including hikers, cyclists, equestrians, ADA-accessibility interests, and District docents and volunteers. The virtual ATTACHMENT 1 Highway 35 Multi-use Trail Crossing and Parking Expansion 17 stakeholder meetings were organized with a brief presentation by District staff, followed by polling questions and open discussion. 5.4 Prior Board and Committee Meetings To date, the Highway 35 Multi-use Crossing and Parking Expansion Feasibility Study has been brought before the District’s Legislative, Funding and Public Affairs Committee (LFPAC) at the following meetings: • September 29, 2020: The LFPAC reviewed the partnership agreement with SFPUC and provided comments. The LFPAC voted unanimously to forward a recommendation to the full Board of Directors to adopt the resolution authorizing the General Manager to execute the grant agreement. (R-20-101, Meeting Minutes) The Highway 35 Multi-use Crossing and Parking Expansion Feasibility Study has also been brought before the full District Board at the following meetings: • October 28, 2020: The Board adopted a resolution authorizing the General Manager to accept grant funding from SFPUC for the proposed Project. (R-20-32, Meeting Minutes) 6.0 Program Elements The Project proposes to expand parking for passenger vehicles and horse trailers. The trailhead would have amenities typical to District preserves, including a vault restroom, trailhead sign boards, boot brush, bike racks, and an equestrian mounting block. The parking lot, trailhead, and restroom would meet ADA accessibility requirements. The Committee is asked to provide feedback on the share of passenger vehicle, horse trailer, and shuttle spaces that should be accommodated as part of the proposed parking expansion design. The share of spaces is based on the expansion potential that exists at the Upper Area, comprised of the existing parking area and the adjacent vacant area to the west, and the Lower Area, comprised of the vacant area adjacent to the employee residence. District staff completed a spatial analysis for the Upper and Lower Areas, which is detailed below (refer also to Figure 5). The Upper Area could accommodate any of the following scenarios: Capacity Scenarios Number of Passenger Vehicle Parking3 Number of Horse Trailer Parking4 Number of Shuttle Bus Parking 5 Scenario 1 65 0 0 Scenario 2 45 4 0 Scenario 3 45 0 4 3 AASHTO Geometric Design of Highways and Streets Exhibit 2-3 Passenger Car (P) 4 AASHTO Geometric Design of Highways and Streets Exhibit 2-21 Passenger Car and Trailer (P/T) 5 AASHTO Geometric Design of Highways and Streets Exhibit 2-8 Conventional School Bus (S-BUS-11 [S-BUS-36]) ATTACHMENT 1 Highway 35 Multi-use Trail Crossing and Parking Expansion 18 The Lower Area could accommodate any of the following scenarios: Capacity Scenarios Number of Passenger Vehicle Parking Number of Horse Trailer Parking Number of Shuttle Bus Parking Scenario 1 15 0 0 Scenario 2 0 2 0 Scenario 3 0 0 2 Staff seeks the Board’s direction on the scenarios to develop final parking program alternatives, which may be a combination of the scenarios listed above and may include other parking elements. For example, one possible combination of these scenarios that maximizes all three uses is to provide 45 passenger vehicles, 2 horse trailer spaces and 2 shuttle spaces in the Upper Area; and 15 passenger vehicle spaces in the Lower Area. The above scenarios are only to demonstrate maximum available space at each expansion area and are not the only parking alternatives that should be considered for the Project. 6.1 Purisima Multimodal Recommendations The Purisima Multimodal Access Study, approved by the Board on November 9, 2022, recommends a series of transportation demand management strategies (TDMs) for the preserve’s parking areas, including the North Ridge parking area. The TDMs considered for the North Ridge parking area are categorized by priority level based on a variety of factors such as ease of implementation, overall effectiveness for improving public access, and interest from the public. The expectation is that many of these strategies will be suitable for the site and be incorporated into the design and long-term management of the parking area TDMs that are being considered for the North Ridge trailhead include the following: Highest priority TDMs • Peak period parking reservations/priority parking • Bicycle parking and facilities (including bicycle repair stations) • Temporarily redesignate spaces on specific days/times to best meet demands o May include designating special parking areas temporarily for carpool, equestrian, shuttle pick-up/drop-off, or other uses • Real-time parking lot occupancy sensors and signage • Electric Vehicle (EV) charging infrastructure Lower priority TDMs • Vehicle way-finding signage • Clearly identify permitted on-street / shoulder parking • Accommodate future shuttle / transit systems ATTACHMENT 1 Highway 35 Multi-use Trail Crossing and Parking Expansion 19 7.0 Figures Figure 1: Project location Figure 2: Project area Figure 3: Existing Conditions Figure 4: On-grade Crossing Recommendations Figure 5: Spatial Analysis ATTACHMENT 1 Midpeninsula Regional Open Space District (Midpen) 3/7/2023 Hwy 35 Multi-Use Trail Crossing and Parking Expansion Feasibility Study Pa t h : G : \ P r o j e c t s \ P u r i s i m a _ C r e e k _ R e d w o o d s \ O u t r e a c h \ P C R _ O u t r e a c h _ 2 0 2 3 0 2 0 6 . m x d Cr e a t e d B y : a c o s t a n z a Midpen preserves Private property While the District strives to use the best available digital data, these data do not represent a legal survey and are merely a graphic illustration of geographic features.
