Home My WebLink About2014-02-24 Ordinance 5232Ordinance No. 5232 Ordinance of the Council ofthe City of Palo Alto Approving and Adopting A Plan of Improvements for the Reconfiguration of the Palo Alto Municipal Golf Course The Council of the City of Palo Alto does ORDAIN as follows: SECTION 1. Findings. The City Council finds and declares that: (a) Article VIII of the Charter of the City of Palo Alto and Section 22.08.005 of the Palo Alto Municipal Code require that, before any substantial building, construction, reconstruction or development is commenced or approved, upon or with respect to any land held by the City for park purposes, the Council shall first cause to be prepared and by ordinance approve and adopt a plan therefor. (b) Palo Alto Municipal Golf Course (the "Golf Course") is dedicated to park and recreational purposes. (c) The City intends to authorize the construction of park improvements (the "Project") within the Golf Course, as shown on the Golf Course Reconfiguration Project Site Plan (Exhibit "A"), and as described below. The Project will result in the reconfiguration of the layout of the entire Golf Course to a modified 18-hole, par 71, regulation-length course that will measure 6,685 yards from the back tees. Approximately 10.5 acres of the existing Golf Course will be reserved for use as a future recreational athletic facility, and 7.4 acres of the Golf Course will be incorporated in the adjacent San Francisquito Creek Flood Reduction Project (the "Flood Reduction Project"). The reconfigured Golf Course's size will be approximately 156 acres, which includes the clubhouse, parking lot and maintenance areas. The existing driving range will be expanded to the north by approximately 8,000 square feet to accommodate approximately six new driving stations or "bays." The Project will include new 6.5-foot-wide concrete golf cart paths, concrete footpaths at the practice putting green area, and compacted gravel maintenance path connections between the concrete cart paths. A pedestrian/bicycle trail will be constructed to link the Bay Trail to the Golf Course clubhouse area. The existing chain link fencei located along the west side of the Golf Course, will be removed and replaced with new chain link fencing as part of the Flood Reduction Project. The reconfigured Golf Course will not result in a change to lighting, operational hours, or number of employees. However, rounds of golf played per year are expected to rise to 67,900 rounds by 2015 and 75,700 rounds by 2017.1n 2011,65,653 rounds of golf were played. 140110 dm 00710332A The Golf Course's reconfiguration will result in the following changes: • Reconfiguration of 18 golf holes • Construction of 18 new greens on the course and 3 new practice greens • Creation of a par 71 course with the following yardages from each of the tees. o Championship Tee: 6,685 o Back Tee: 6,091 o Regular Tee: 5,374 o Forward Tee: 4,588 • Reconstruction or construction of all new bunkers • Transformation of 55 irrigated acres to naturalized areas (non-managed turf) plus 7.5 acres to the realigned San Francisquito Creek • Reduction in irrigated turf from 135 acres to 81.7 acres • Construction of new player development area/practice green/short game area and Youth Golf Area • Expansion of the practice range tee area • Installation of new sign age • Replacement of the entire Golf Course irrigation system • Construction of a new restroom that is accessible at Holes 4, 12 and 15 (d) The Project is consistent with park and recreation purposes. (e) The Council desires to approve the Project, described above, and as more specifically described in Golf Course Reconfiguration Project Site Plan, attached hereto as Exhibit "A." SECTION 2. The Council hereby approves the construction of the improvements at the Palo Alto Municipal Golf Course, and it hereby adopts the Golf Course Reconfiguration Project Site Plan as part of the official plan for the construction of the park improvements at the Palo Alto Municipal Golf Course. SECTION 3. The Council finds that the Project (to construct the improvements at the Palo Alto Municipal Golf Course) under the California Environmental Quality Act requires an Environmental Impact Report, which has been completed. II II II 140110 dm 00710332A SECTION 4. This ordinance shall be effective on the thirty-first day after the date of its adoption.

When a lead agency makes findings on significant effects identified in an EIR, it must also adopt a program for reporting or monitoring mitigation measures that were adopted or made conditions of project approval (Public Resources Code [PRC] Section 21081.6[a]; State CEQA Guidelines Sections 15091[d], 15097). This document represents the mitigation monitoring and reporting program (MMRP) prepared by the City of Palo Alto for the Project. This MMRP includes all measures required to reduce potentially significant environmental impacts to.a less-than-significant level. It also identifies the timing of implementation, the agency responsible for implementing the mitigation, and the agency responsible for monitoring the mitigation. The mitigation measures, timing, and responsibility are summarized in Tables 1 and 2, and the full text of the mitigation measures follows. Table 1lists the mitigation measures required for the Golf Course Reconfiguration and Table 2 lists the mitigation measures required for the Baylands Athletic Center Expansion. This MMRP has been prepared by the City of Palo Alto, with technical assistance from ICF International, an environmental consulting firm. Questions should be directed to Joe Teresi at the City of Palo Alto.

Lighting will conform to the City's applicable zoning regulations to minimize visual impacts (PAMC Section 18.23.030) and will be subject to Site and Design review approval (PAMC 18. 76) to ensure appropriate light pollution and glare reduction standards are achieved. To meet. City requirements, lighting will be designed using Illuminating Engineering Society's design guidelines and in compliance with International Dark-Sky Association approved fixtures. All lighting is to provide minimum impact to the surrounding environment and will use downcast, cut-off type fixtures that are shielded and direct the light only towards objects requiring illumination. Therefore, lights Will be installed at the lowest allowable height and cast low-angle illumination while minimizing incidental light spill onto adjacent properties, open spaces, or backscatter into the nighttime sky. The lowest allowable wattage will be used for all lighted areas and the amount of nighttime lights needed to light an area will be minimized to the highest degree possible. Light fixtures will have non-glare finishes that will not cause reflective daytime glare. All outdoor lighting will be with individual photocells. Lighting will be designed for energy efficiency, use high pressure sodium vapor lights with individual photocells, and have daylight sensors or be timed with an on/ off program. Lights will provide good color rendering with natural light qualities with the minimum intensity feasible for security, safety, and personnel access. Lighting, including light color rendering and fixture types, will be designed to be aesthetically pleasing. Lights along pathways and safety lighting at building entrances and loading areas will employ shielding to minimize offsite light spill and glare and be screened and directed away from residences and adjacent uses to the highest degree possible. The amount of nighttime lights used along pathways will be minimized to the highest degree possible to ensure that spaces are not unnecessarily over-lit. For example, the amount of light can be reduced by limiting the amount of ornamental light posts to higher use areas and by using hooded wall mounts or bollard lighting on travel way portions of pathways. Stadium lighting will employ spill and glare control features to minimize off-site light pollution. Luminaires will be chosen for the ability to provide horizontal and vertical beam control for better control in directing what is illuminated. In addition, shielding, such as a visor, will be used to further direct light and reduce light spill and ambient light glow. Luminaires will also incorporate photometric reflector systems that are designed to reduce light pollution. All design measures used to reduce light pollution will employ the technologies available at the time of project design to allow for the highest potential to reduce light pollution and meet City standards. These technologies may be available through information and products endorsed by the Illuminating Engineering Society and International Dark-Sky Association in addition to the actual Palo Alto Municipal Golf Course Reconfiguration and Baylands Athletic Center Expansion Project MMRP 9 January 2014 ICF 00631.12 City of Palo Alto Mitigation Monitoring and Reporting Program products that lighting manufacturers have developed to improve lighting technologies and reduce light pollution and glare. Mitigation Measure AES-2: Reconfigure Baseball and Softball Field Lighting to Meet or Reduce Existing Levels Any reconfiguration of the baseball and softball field lighting will conform to the lighting standards described in PAMC Section 18.23.030 and will, at a minimum, be designed to create no net increase in the amount of light spill and ambient light glow produced when compared to existing conditions. If feasible, measures will be taken to reduce the amount of light spill and ambient light glow produced through the reconfiguration when compared to existing conditions using measures specified in Mitigation Measure AES-1. Air Quality Mitigation Measure AQ-1: Implement Tailpipe Emission Reduction for Project Construction The City of Palo Alto will require all construction contractors to implement the BAAQMD' s exhaust Basic Construction Mitigation Measures and Additional Construction Mitigation Measures recommended by BAAQMD to control exhaust emissions. Emission reduction measures will include at least the following measures and may include other measures identified as appropriate by the Air District and/or contractor: • Idling times shall be minimized either by shutting equipment off when not in use or reducing the maximum idling time to 2 minutes. Clear signage shall be provided for construction workers at all access points. • All construction equipment shall be maintained and properly tuned in accordance with manufacturer's specifications. All equipment shall be checked by a certified visible emissions evaluator. • The simultaneous occurrence of excavation, grading, and ground-disturbing construction activities in the same area at any one time shall be limited. Activities shall be phased to reduce the amount of disturbed surfaces at any one time. • The construction contractor shall develop a plan for submittal to the City that demonstrates that the off-road equipment (more than 50 horsepower) to be used in construction of the Project (i.e., owned, leased, and subcontractor vehicles) will achieve a Project-wide fleet-average 20 percent NOX reduction. Acceptable options for reducing emissions include the use oflate-model engines, low-emission diesel products, alternative fuels, engine retrofit technology, after- treatment products, add-on devices such as particulate filters, and/ or other options as such become available. • All construction equipment, diesel trucks, and generators shall be required to be equipped with Best Available Control Technology for emission reductions of N OX and PM. • All contractors shall be required to use equipment that meets CARB's most recent certification standard for off-road heavy-duty diesel engines. Palo Alto Municipal Golf Course Reconfiguration and Baylands Athletic Center Expansion Project MMRP 10 January 2014 ICF 00631.12 City of Palo Alto Mitigation Monitoring and Reporting Program Mitigation Measure AQ-2: Implement BAAQMD Basic Construction Mitigation Measures to Reduce Construction-Related Dust The BMQMD will require all construction contractors to implement the Basic Construction Mitigation Measures recommended by BMQMD to reduce dust emissions. Emission reduction measures will include at least the following measures and may include other measures identified as appropriate by the Air District and/or contractor: • All exposed surfaces (e.g., parking areas, staging areas, soil piles, graded areas, and unpaved access roads) shall be watered two times per day. • All haul trucks transporting soil, sand, or other loose material off-site shall be covered. • All visible mud or dirt track-out onto adjacent public roads shall be removed using wet power vacuum street sweepers at least once per day. The use of dry power sweeping is prohibited. • All vehicle speeds on unpaved roads shall be limited to 15 mph. • All roadways, driveways, and sidewalks to be paved shall be completed as soon as possible. Building pads shall be laid as soon as possible after grading unless seeding or soil binders are used. • A publicly visible sign shall be posted with the telephone number and name of the person to contact at the lead agency regarding dust complaints. This person shall respond and take corrective action within 48 hours. The BMQMD's phone number shall also be visible to ensure compliance with C;lpplicable regulations. Biologica I Resources Mitigation Measure 810-1: Develop and Implement Worker Awareness Training Prior to construction, Worker Awareness Training will be conducted by a qualified biologist to inform construction project workers of their responsibilities regarding sensitive environmental resources. The training will include environmental education about sensitive plant species (Alkali milk vetch, San Joaquin spearscale, Congdon's tarplant, Point Reyes bird's-beak, lost thistle, fragrant fritillary, woodland woollythreads, hairless popcorn flower, California seablite, Showy Rancheria clover, and saline clover), western pond turtles, nesting raptors and migratory birds including western burrowing owl, California clapper rail, California black rail, salt marsh harvest mouse, salt marsh wandering shrew, California red-legged frog, and San Francisco garter snake, as well as sensitive resources (e.g., trees, wetlands). The training will include information regarding protected status of the resource, visual aids to assist in identification of regulated biological resources, and actions to take should protected wildlife and biological resources be observed within the Project site. Qualified biologists will be on call and will regularly survey the site during construction. Palo Alto Municipal Golf Course Reconfiguration and Baylands Athletic Center Expansion Project MMRP 11 January 2014 ICF 00631.12 City of Palo Alto Mitigation Monitoring and Reporting Program Mitigation Measure BI0-2a: Conduct Preconstruction Botanical Surveys The City will retain a qualified botanist to survey suitable habitat in the Project site for the presence of special-status plants. Surveys will be conducted during the appropriate blooming periods as indicated in Table 3.3-4. Table 3.3-4. Timing of Surveys for Special-Status Plants Species Blooming Period Alkali milkvetch March-June San Joaquin spearscale April-October Congdon's tarplant June-November Point Reyes bird's-beak June-October Lost thistle June-July Fragrant fritillary February-April Woodland woollythreads February-July Hairless popcorn-flower April-May California seablite July-October Showy rancheria clover April-June Saline clover April-June Period Surveys Should Occur• April-May July-August July-August July-August June-July February-April February-July April-May July-August April-May April-May a Exact timing of surveys should account for annual variations in climate and weather; surveys should be timed to coincide with blooming periods of known local populations whenever possible. Surveys will follow the CNPS Botanical Survey Guidelines (California Native Plant Society 2001) and occur 1 year prior to the start of construction. Since historical and recent routine disturbance has occurred on the project site, the potential for special-status plants to occur is reduced and only one season of surveys is expected to be necessary. Special-status plants identified during the surveys will be mapped using a handheld global positioning system unit and documented as part of the public record. A report of occurrences will be submitted to the City and the CNDDB. Surveys will be completed before ground-disturbing activities begin; survey timing will allow for follow-up mitigation, if needed. This may include seed collection or transplanting. If it is determined that individuals of identified special-status plant species could be affected by construction traffic or activities, Mitigation Measure BI0-2b and, if necessary, Mitigation Measure BI0-2c, will be implemented. Mitigation Measure BI0-2b: Confine Construction Disturbance and Protect Special-Status Plants during Construction Construction disturbance will be confined to the minimum area necessary to complete the work, and . will avoid encroachment on adjacent habitat. If special-status plants are found, a setback buffer will be established around individuals or the area occupied by the population, based on judgment of a qualified botanist. The plants and a species-appropriate buffer area determined in consultation with Palo Alto Municipal Golf Course Reconfiguration and Baylands Athletic Center Expansion Project MMRP 12 January 2014 ICF 00631.12 City of Palo Alto Mitigation Monitoring and Reporting Program agency (CDFW and USFWS) staff will be protected from encroachment and damage during construction by installing temporary construction fencing to make crews visually aware of the plant population. Fencing will be brightly colored and highly visible. Fencing will be installed under the supervision of a qualified botanist to ensure proper location and to prevent damage to plants or the seed bank during installation. Fencing will be installed before site preparation or construction work begins and will remain in place for the duration of construction. Construction personnel will be prohibited from entering these areas (the exclusion zone) for the duration of Project construction. Fencing installation will be coordinated with fence installation required by other mitigation measures protecting wetlands, riparian habitat, and mature trees. If special-status plant species cannot be avoided during construction activities, then both Mitigation Measures BI0-2c and BI0-2d will be implemented. Mitigation Measure BI0-2c: Compensate for Loss of Special-Status Plants If any individually listed special-status plant is present and cannot be effectively avoided through implementation of Mitigation Measure BI0-2b, the City will develop and implement a compensation plan. The compensation plan will preserve an offsite area containing individuals of the affected species. The plan will be implemented so that there is no net loss of special-status plants. If an offsite population is not available for preservation, the City will employ a qualified nursery to collect and propagate the affected species, collected at the appropriate time of year, prior to population disturbance at the affected areas of the Project. Transplantation will also be implemented if practicable for the species affected, including mature native plants to the extent feasible. The compensation plan will be developed by a qualified botanist in coordination with and approval of CD FW or USFWS, depending on whether the plant has state or federal status, respectively, or . both. The compensation area will contain a population and/or acreage equal to or greater than that lost as a result of Project implementation and will include adjacent areas as needed to preserve the special-status plant population in perpetuity. The quality ofthe population preserved will also be equal to or greater than that of the affected population, as determined by a qualified botanist retained by the City. Compensation sites and populations will be subject to CDFW and USFWS approval. The City will be responsible for ensuring that the compensation area is acquired in fee or in conservation easement, maintained for the benefit of the special-status plant population in perpetuity, and funded through the establishment of an endowment. A monitoring and adaptive management plan will also be developed for each compensation site and will be similarly be subject to CDFW and USFWS approval. Mitigation Measure BI0-2d: Develop and Implement Special-Status Plant Species Monitoring Plan If any special-status plants are present and cannot be effectively avoided through implementation of Mitigation Measure BI0-2b, the City will develop and implement a monitoring plan. The monitoring plan will cover a span of 5 years beginning when construction is complete. The City will hire a qualified biologist or botanist to conduct the monitoring plan. Special-status plants found during the preconstruction botanical surveys for Mitigation Measure BI0-2a will be mapped and identified. The qualified biologist will monitor the status of those same populations once a year for five years, during the respective blooming seasons for each species. Golf Course staff will be aware of the Palo Alto Municipal Golf Course Reconfiguration and Baylands Athletic Center Expansion Project MMRP 13 January 2014 ICF 00631.12 City of Palo Alto Mitigation Monitoring and Reporting Program location of the special-status plant species to ensure that no operation and maintenance activities will disturb the existing populations. If the certain plant species' populations are unsuccessful, the City will reseed/plant suitable habitat and resume monitoring activities until the success criteria established by the monitoring plan are fully satisfied. Mitigation Measure BI0-2e: Deposit Landscape Waste Exclusively in Developed or Ruderal Areas Absent of Special-Status Plant Species Training will take place after Project construction is complete to educate Golf Course staff in the importance of the presence of special-status plant species. The training will include a handout of pertinent special-status plant species' pictures, relevant regulations and legal protections, and an in- person meeting with Golf Course staff and a qualified biologist/botanist. Golf Course staff will only be permitted to deposit landscape waste in developed or ruderal areas absent of special-status plant species (including the proposed 25-foot buffer between the Golf Course and the Athletic Center), as determined through the botanical surveys proposed in Mitigation Measure BI0-2a during the construction phase. Special-status plant species will be marked and protected clearly, so Golf Course staff will be aware of appropriate deposit areas, as well as sensitive areas to avoid. Mitigation Measure BI0-3: Establish Buffer Zones for Nesting Raptors and Migratory Birds Prior to the start of construction activities that begin during the migratory bird nesting period (between February 1 and August 31 of any year), the City will retain a qualified wildlife biologist to conduct a survey for nesting raptors and migratory birds, including special-status species such as salt marsh common yellowthroat, Alameda song sparrow, northern harrier, and white-tailed kite, at a time(s) of day most opportune for active nest identification. Surveys will cover all suitable raptor and migratory bird nesting habitat that will be impacted directly or indirectly through disturbance, including habitat potentially used by ground-nesting migratory bird species. If an active nest is discovered during these surveys, the qualified wildlife biologist will establish a no-disturbance buffer zone around the nest tree (or, for ground-nesting species, the nest itself). The no-disturbance zone will be marked with flagging or fencing that is easily identified by the construction crew and will not affect the nesting bird. In general, the minimum buffer zone widths will be 25 feet (radius) for non-raptor ground-nesting species; 50 feet (radius) for nonraptor shrub- and tree-nesting species; and 250 feet (radius) for all raptor species. Buffer widths may be modified based on discussion with CD FW, depending on the proximity of the nest, whether the nest would have a direct line of sight to construction activities, existing disturbance levels at the nest, local topography and vegetation, the nature of proposed activities, and the species potentially affected. Buffers will remain in place as long as the nest is active or young remain in the area. No construction presence or activity of any kind will be permitted within a buffer zone until the biologist determines that the young have fledged and moved away from the area and the nest is no longer active. If monitoring of active nests indicates that disturbance is affecting active nests, buffer widths will be increased until the disturbance no longer affects the nest(s) as determined by the biologist. If the buffer cannot be extended further, then work within the area will stop until the nest is no longer active. Palo Alto Municipal Golf Course Reconfiguration and Baylands Athletic Center Expansion Project MMRP 14 January 2014 ICF 00631.12 City of Palo Alto Mitigation Monitoring and Reporting Program Mitigation Measure BI0-4: Implement Survey and Avoidance Measures for Western Burrowing Owls Prior to Construction Activities Prior to any construction activity planned to begin during the fall and winter nonnesting season (September 1-January 31 ), the City will retain a qualified wildlife biologist to conduct a preconstruction survey for burrowing owls. Surveys will follow the protocol outlined by the California Burrowing Owl Consortium (CBOC) (1993) and the 2012 CDFW staff report. If any burrows occupied by western burrowing owls are found within the disturbance area during the survey or at any time during the construction process, the City will notify CD FW and will proceed under CDFW direction. If construction is planned to occur during the nesting season (February 1- August 31 ), sutveys for nesting owls will be conducted by a qualified wildlife biologist in the year prior to construction to determine if there is breeding within 2 50 feet of the construction footprint. This prior-year survey will provide the Project team advance notice regarding nesting owls in the Project site and allow ample time to discuss with CDFW the appropriate course of action if nesting owls are found. In addition, same-year preconstruction surveys for nesting western burrowing owls will be conducted no more than 7 days prior to ground disturbance in all suitable burrowing owl habitat to ensure owls can be avoided. If the biologist identifies the presence of a nesting burrowing owl in an area scheduled to be disturbed by construction, a 250-foot no-activity buffer will be established and maintained around the nest while it is active. Surveys and buffer establishment will be performed by qualified wildlife biologists, will be coordinated with CDFW, and will be subject to CDFW review and oversight. Mitigation Measure 810-5: Implement Survey and Avoidance Measures for California Clapper Rail and California Black Rail Prior to Construction Activities If work is to be conducted during California clapper rail and California black rail breeding and rearing seasons (March 1-August 31) within 700 feet of suitable habitat, the City will retain a permitted biologist to conduct protocol-level surveys at the Project site including rail call surveys and rail-track surveys in appropriate habitat for California clapper rail and California black rail (California Coastal Conservancy 2011). The surveys will be conducted no more than 48 hours prior to commencement of construction and maintenance activities and will be performed at dawn or dusk, the vocalization periods of highest intensity. Project activities occurring within 700 feet of active nests will be postponed until after young have fledged, unless activities are behind a levee and will not affect any active nests as determined by the biologist. Outside of breeding season, the City will retain a permitted biologist to conduct surveys of appropriate habitat for California clapper rail and California black rail within the work area, including all staging and access routes, no more than 7 days prior to initiation of work within suitable habitat. If individuals are observed during this survey, a biologist will conduct an additional survey immediately prior to initiation of construction activities. If individuals are observed within or near the work area, a no-disturbance buffer (minimum 50 feet) will be implemented. If the daily work area is expanded, then a qualified biologist will survey the suitable habitat prior to initiation of work and movement of equipment that day. No work will occur within the buffer until the biologist verifies that California clapper rail or California black rail individuals have left the area. If individuals are routinely detected in the work area, a species avoidance plan will be developed in coordination with USFWS and CDFW. If no individuals are detected during surveys, no buffers will Palo Alto Municipal Golf Course Reconfiguration and Baylands Athletic Center Expansion Project MMRP 15 January 2014 ICF 00631.12 City of Palo Alto Mitigation Monitoring and Reporting Program be required. All vegetation removal within suitable habitat of these species, as determined by a biologist, will be done by hand to the extent possible. If movement of heavy equipment in necessary in suitable habitat or within 50 feet (audibly or visually) of habitat, then a biological monitor will observe the area in front of the equipment from a safe vantage point. If these species are detected within the area in front of the equipment, then the equipment will stop and the biologist will direct the equipment on an alternative path. If this is not possible, then equipment will stop until a clear path can be identified. Mitigation Measure BI0-6: Implement Survey and Avoidance Measures for Salt Marsh Harvest Mouse and Salt Marsh Wandering Shrew Prior to Construction Activities Prior to initiation of work within suitable habitat, a permitted biologist will be retained to monitor the hand removal of pickleweed to avoid impacts on salt marsh harvest mouse and salt marsh wandering shrew. Monitoring will occur for the duration of all clearing work within suitable habitat, and all clearing of pickleweed will be conducted by hand. If salt marsh harvest mouse or salt marsh wandering shrew are observed during clearing activities, clearing will cease and workers will move to a new area. Clearing work may begin in the area of the observation 1 day or more after the observation date. During the survey, if salt marsh harvest mouse or salt marsh wandering shrew individuals are observed, or if active nests of these species are observed, proposed Project activities within 100 feet of the observation will be postponed and a no-disturbance buffer will be established. The buffer will remain in place until the biologist determines that the individuals have left the area and are not present in or near (100 feet) of the work area. If no individuals are observed in accordance with the survey protocols, no buffers will be required. If salt marsh harvest mouse or salt marsh wandering shrew are observed within wetlands proposed to be affected by the Project, then a habitat avoidance, impact minimization, and compensation plant will be developed, in coordination with USFWS and CDFW, prior to alteration of occupied habitat. If neither species is observed during preconstruction surveys, then no further mitigation associated with this measure is necessary. If salt marsh harvest mouse or salt marsh wandering shrew are observed within the Project Area, construction and maintenance work, including site preparation, will be avoided to the extent possible within suitable habitat for these species during their breeding seasons (February 1 to November 30). As work during the species' breeding seasons will be necessary, a species avoidance plan will be developed in consultation with USFWS and CDFW, and implemented. The avoidance plan, at a minimum, will include the following. • Hand removal of vegetation will start at the edge farthest from the largest contiguous salt marsh area and work its way towards the salt marsh, providing cover for salt marsh harvest mice and allowing them to move towards the salt marsh as vegetation is being removed. • In consultation with CD FW, exclusion fencing will be placed around a defined work area immediately following vegetation removal and before Project activities begin. The final design and proposed location of the fencing will be reviewed and approved by CD FW prior to placement. Palo Alto Municipal Golf Course Reconfiguration and Baylands Athletic Center Expansion Project MMRP 16 January 2014 ICF 00631.12 City of Palo Alto Mitigation Monitoring and Reporting Program • Prior to initiation of work each day within 300 feet of pickelweed habitats, a qualified biologist will thoroughly inspect the work area and adjacent habitat areas to determine if saltmarsh harvest mice are present. The biologist will ensure the exclusion fencing has no holes or rips and the base remains buried. The fenced area will be inspected daily to ensure that no mice are trapped. Mitigation Measure 8I0-7: Avoid and Protect Jurisdictional Wetlands during Construction The City will ensure that a qualified resource specialist (biologist, ecologist, or soil scientist) will clearly identify wetland areas to be preserved and wetland areas outside of the direct impact footprint with temporary orange construction fencing before site preparation and construction activities begin at each site or will implement another suitable low-impact measure. Construction will not encroach upon jurisdictional wetlands identified by the wetland specialist. The resource specialist will use the Project's wetland delineation (ICF International 2013) to confirm the location of wetland boundaries based on existing conditions at the time of the survey. Exclusion fencing will be installed before construction activities are initiated, and the fencing will be maintained throughout the construction period. No construction activity, traffic, equipment, or materials will be permitted in fenced wetland areas. Mitigation Measure 8I0-8: Compensate for Impacts to Jurisdictional Wetlands and Waters of the United States prior to Project-Related Impacts during Construction The City will develop a wetland/waters of the United States mitigation monitoring plan (MMP), subject to approval by the USACE, that will ensure no net loss of wetlands will result from the Project's impacts. The details of site restoration, monitoring, and adaptive management will be included in the MMP in compliance with the Clean Water Act. The MMP will include success criteria that will be assessed by comparing performance during the monitoring period against objective and verifiable, ecologically-based success criteria that reflect the goals and objectives of the site. Examples of success criteria may include, but are no.t limited to: (1) period of inundation similar to other wetlands of the same type in the South Bay region, (2) percent vegetation cover, and (3) plant species composition similar to other wetlands of the same type in the South Bay region, all aimed at replacing the functions and values that were lost in the wetland that was removed. The monitoring period will be a 5-year period; the success criteria for this period must be satisfied in at least 3 of the 5 years, but if the success criteria are not so satisfied, then the monitoring period will be extended from year to year until the success criteria are satisfied within a consecutive period of 3 years. The City will retain a qualified biologist to conduct annual monitoring to assess establishment of wetland vegetation and wetland function, and if necessary, implement adaptive management actions (including replanting, nonnative species removal, etc.) to ensure that there is no net loss of wetland habitat. Wetland compensation habitat will be set aside and protected in perpetuity through appropriate legal means, consistent with U.S. Army Corps of Engineers' requirements and as specified in permits. The City will be responsible for all associated costs and logistics. The Project proposes to create and restore existing wetlands within the Golf Course, resulting in a total of 12.168 acres of wetlands. The plan will detail the amount and type of wetlands (based on the Project's wetland delineation once verified) that will compensate (through preservation, creation, and/or restoration) for Project impacts to existing wetlands/waters of the United States, and outline Palo Alto Municipal Golf Course Reconfiguration and Baylands Athletic Center Expansion Project MMRP 17 January 2014 ICF 00631.12 City of Palo Alto Mitigation Monitoring and Reporting Program the monitoring and success criteria for the compensation wetlands/waters of the United States. Once the plan is approved, the City will implement its wetland/waters of the state compensation measures. Wetland creation and enhancement activities will be completed concurrent with the completion of the Project, after which the City will retain a qualified biologist to monitor the compensation features per the MMP. Mitigation Measure 810-9: Compensate for Loss of Protected Landscape Trees by planting both On-Site and Off-Site, Consistent with Applicable Tree Protection Regulations Regulated trees that are removed will be replaced through a combination of on-site replacement with native Baylands-appropriate trees, protection of naturally-generated oak saplings in the Arastradero Preserve andjor other Foothills locations, and restoration of native Bay ecosystem areas to a total of 1 acre in close proximity to the Project The landscaping plan for tree mitigation will specifically identify the locations where replacement trees, oak sapling protection, and native Bay ecosystem restoration areas are to be planted; mitigation will occur both on-site and offsite. Offsite locations include Baylands locations near the Project site, the Arastradero Preserve and/or other locations in the foothills. The on-site tree replacement will consist of the planting of 300 native trees on the reconfigured golf course as part of the Project. The off-site tree protection will consist of the placement of protective cages around 500 naturally-occurring oak saplings on the Arastradero Preserve in order to prevent browsing by deer until the trees have matured adequately to ensure their long-term survival. The off-site native Bay ecosystem restoration will consist of the planting of 1 acre or more of native grasses and shrubs at a site or sites within the Baylands in close proximity to the Project site. The final mitigation landscaping plan will be subject to review and approval by the City. Newly planted trees, protected saplings, and restored native Bay ecosystem areas will be monitored by the City staff and/or a contactor at least once a year for 3 years. Each year, any vegetation that does not survive will be replaced consistent with the City of Palo Alto Tree Technical Manual. Any vegetation and/or native plant material that does not survive will be replaced and monitored for an additional 3 years. Mitigation Measure 810-10: Protect Remaining Trees from Construction Impacts Trees not designated for removal will be protected from damage during construction by the installation of temporary fencing and other methods determined necessary and prescribed in the City of Palo Alto Tree Technical Manual such as, but not limited to, trunk wrapping, root mulching, and access route gravelling, consistent with International Society of Arboriculture tree protection zone recommendations. Fencing will be installed outside of the tree's drip line to keep construction equipment away from trees and prevent unnecessary damage to or loss of regulated trees on the project site. Any regulated trees retained on the site and located adjacent to construction activities will be monitored monthly during the term of construction and replaced off-site if they do not . survive through the monitoring period. Consistent with Section 2.30 in the City of Palo Alto's Tree Technical Manuall, an ISA certified arborist will conduct monthly inspections to monitor tree health conditions and document such observations in a monthly inspection report.

Cultural Resources Mitigation Measure CUL-l: Conduct Worker Awareness Training for Archaeological Resources Prior to Construction Prior to the initiation of any site preparation and/or start of construction, the applicant will ensure that all construction workers receive training overseen by a qualified professional archaeologist who is experienced in teaching nonspecialists, to ensure that forepersons and field supervisors can recognize archaeological resources (e.g., areas of shellfish remains, chipped stone or groundstone, historic debris, building foundations, human bone) in the event that any are discovered during construction. Mitigation Measure CUL-2: Stop Work if Cultural Resources, Including Human Remains, are Encountered during Ground-Disturbing Activities The applicant will ensure the construction specifications include a stop work order if prehistoric or historic-period cultural materials are unearthed during ground-disturbing activities. All work within 100 feet of the find will be stopped until a qualified archaeologist and Native American representative can assess the significance of the find. Prehistoric materials might include obsidian and chert flaked-stone tools (e.g., projectile points, knives, scrapers) or tool making debris; culturally darkened soil ("midden") containing heat-affected rocks and artifacts; stone milling equipment (e.g., mortars, pestles, handstones, or milling slabs); and battered-stone tools, such as hammerstones and pitted stones. Historic-period materials might include stone, concrete, or adobe footings and walls; filled wells or privies; and deposits of metal, glass, and/ or ceramic refuse. If the find is determined to be potentially significant, the archaeologist, in consultation with the Native American representative, will develop a treatment plan that could include site avoidance, capping, or data recovery. Mitigation Measure CUL-3: Conduct a Preconstruction Paleontological Resources Field Survey and Paleontological Resources Inventory and Evaluation The City will retain qualified personnel with experience in vertebrate fossil monitoring and salvage at construction sites to conduct a paleontological resources field survey with native soils to determine whether significant resources exist within the Project site. The inventory and evaluation will include the documentation and result of these efforts, the evaluation of any paleontological resources identified during the survey, and paleontological resources monitoring, if the survey identifies that it is necessary. Mitigation Measure CUL-4: Conduct Worker Awareness Training for Paleontological Resources Prior to Construction · Prior to the initiation of any site preparation and/or start of construction, the applicant will ensure that all construction workers receive training overseen by a qualified professional paleontologist Palo Alto Municipal Golf Course Reconfiguration and Baylands Athletic Center Expansion Project MMRP 19 January 2014 ICF 00631.12 City of Palo Alto Mitigation Monitoring and Reporting Program who is experienced in teaching nonspecialists, to ensure that forepersons and field supervisors can recognize paleontological resources in the event that any are discovered during construction. Mitigation Measure CUL-5: Stop Work if Paleontological Resources are Encountered during Ground-Disturbing Activities If paleontological resources are discovered during ground-disturbing activities, work will stop in that area and within 100 feet of the find until a qualified paleontologist with experience in vertebrate fossil monitoring and salvage at construction sites can assess the significance of the find and, if necessary, develop appropriate treatment measures in consultation with the City and other agencies as appropriate. Equipment operators, supervisors, inspectors, and other field personnel will be required to report to the paleontology monitor any suspected fossil discoveries. The paleontologist will have authority to halt or redirect excavation operations in the event of discovery of vertebrate, plant, or invertebrate fossils until such time as their probable significance can be assessed and, if potentially significant, appropriate salvage measures have been implemented. The paleontologist will properly collect and document any large vertebrate remains and recognize and appropriately sample and document any sedimentary bodies revealing small vertebrate remains. Large bulk samples may be appropriate. Minimum documentation includes exact location (GPS data), orientation, depth (elevation), and detailed geologic setting of any large-or small- vertebrate finds, including detailed diagrams showing microstratigraphy in nearby excavations supplemented with good-quality field photographs. If vertebrate fossils are discovered in spoils piles during excavation, the paleontologist will make every effort to locate and record the original site of the specimen( s) prior to disturbance. Salvage of potentially significant specimens discovered in situ in excavated surfaces will be conducted by the paleontologist in compliance with all safety regulations and with implementation of all feasible precautions. The onsite safety inspector will hold final authority to determine whether each proposed salvage operation is consistent with established safety policies at the site. Excavation equipment and operators will be made available for short periods to remove overburden above in situ specimens, to improve safety conditions during salvage operations, or to aid in transport within the site boundaries of any large salvaged specimens which cannot be safely transported by hand. Any potentially significant fossils recovered during the monitoring and salvage phase will be cleaned, repaired, and hardened to the level required by the repository institution, and will be donated to that institution. Any collected bulk sediment samples having the potential for small fossil vertebrate remains will be wet-or dry-screened and processed as necessary for recovery of the included fossils. Details of requirements and conditions for transfer of salvaged specimens to the repository museum will be arranged with the museum as soon as the scope of the salvaged· collection becomes apparent, and will be in accordance with the recommendations outlined in the SVP Guidelines (1995). On completion of the above tasks, the supervising paleontologist will prepare a final report on the implementation of the mitigation plan and results and submit it to the appropriate parties, institutions, and government agencies. Palo Alto Municipal Golf Course Reconfiguration and Baylands Athletic Center Expansion Project MMRP 20 January 2014 ICF 00631.12 City of Palo Alto Mitigation Monitoring and Reporting Program Geology and Soils Mitigation Measure GE0-1: Stockpile Topsoil during Earthwork Activities and Reuse the Topsoil Onsite during Revegetation as Needed The contractor( s) retained for construction and re-vegetation of the proposed Project will be required to stockpile excavated native topsoil so it can be reused for re-vegetation on the Project site as needed. To ensure maximum topsoil recovery, topsoil will be stockpiled separately from other excavated materials. Greenhouse Gas Emissions and Climate Change Mitigation Measure GHG-1: Implement BAAQMD Best Management Practices for Construction The City will require all construction contractors to implement the BMPs recommended by the BAAQMD to reduce GHG emissions. Emission reduction measures will include, at a minimum, the following measures. • Use local building materials of at least 10 percent; and • Recycle or reuse at least 50 percent of construction waste or demolition materials. Hazards and Hazardous Materials Mitigation Measure HAZ-1: Preparation and Implementation of a Spill Prevention, Control, and Countermeasure Plan The project applicant with prepare and implement a Spill Prevention, Control, and Countermeasure (SPCC) Plan to minimize the potential for, and effects from, accidental spills of hazardous, toxic, or petroleum substances during construction of the project. The SPCC will be completed before any construction activities begin. Mitigation Measure HAZ-2: Require Proper Storage and Handling of Potential Pollutants and Hazardous Materials The storage and handling of potential pollutants and hazardous materials, including, but not necessarily limited to, gasoline, diesel, oils, paint, and solvents, will be in accordance with all local, state and federal laws and other requirements. Temporary storage enclosures, double walled tanks, berms, or other protective facilities will be provided as required by law. All hazardous materials will be stored and handed in strict accordance with the Material Safety Data Sheets for each product. A copy of each Materials Safety Data Sheet will be submitted to the Project Engineer at the time of delivery of the products to the Project site. Palo Alto Municipal Golf Course Reconfiguration and Baylands Athletic Center Expansion Project MMRP 21 January 2014 ICF 00631.12 City of Palo Alto Mitigation Monitoring and Reporting Program Mitigation Measure HAZ-3: Stop Work and Implement Hazardous Materials Investigations and Remediation in the Event that Unknown Hazardous Materials Are Encountered In the event that unknown hazardous materials are encountered during construction monitoring or testing of soil suitability, all work in the area of the discovery will stop and a Phase II hazardous materials investigation will be conducted to identify the nature and extent of contamination and evaluate potential impacts on Project construction and human health. If necessary, based on the outcomes of the Phase II investigation, the City of Palo Alto will implement remediation measures consistent with all applicable local, state, and federal codes and regulations. Construction in areas known or reasonably suspected to be contaminated will not resume until remediation is complete. If waste disposal is necessary, the City of Palo Alto will ensure that all hazardous materials removed during construction are handled and disposed of by a licensed waste-disposal contractor and transported by a licensed hauler to an appropriately licensed and permitted disposal or recycling facility, in accordance with local, state, and federal requirements. Mitigation Measure HAZ-4: Implement Engineering Controls and Best Management Practices during Construction During construction the contractor shall employ use of engineering controls and BMPs to minimize human exposure to potential contaminants. Engineering controls and construction BMPs shall include but not be limited to the following. • Contractor employees working onsite shall be certified in OSHA's 40-hour Hazardous Waste Operations and Emergency Response (HAZWOPER) training. • Contractor shall monitor area around construction site for fugitive vapor emissions with appropriate field screening instrumentation. Mitigation Measure HAZ-5: Prevent Mosquito Breeding During Project Construction To prevent mosquito breeding during Project construction, the Contractor will ensure that standing water that accumulates on the construction site is gone within four days (96 hours). All outdoor grounds will be examined and unnecessary water that may stand longer than 96 hours will be drained. Construction personnel will property dispose of unwanted or unused artificial containers and tires. If possible, any container or object that holds standing water that must remain outdoors will be covered, inverted, or have drainage holes drilled. Hydrology and Water Quality Mitigation Measure HYD-1: Use of Artificial Turf with High Permeability for Athletic Fields In order to ensure for adequate groundwater infiltration as part of the Athletic Center Expansion, which includes up to five full size athletic fields, the type of artificial turf (synthetic grass) in the athletic fields could be changed to a design that allows for increased surface-ground penetration (City of Palo Alto 2012b ). While artificial turf coating often allows for water to quickly pass through Palo Alto Municipal Golf Course Reconfiguration and Baylands Athletic Center Expansion Project MMRP 22 January 2014 ICF 00631.12 City of Palo Alto Mitigation Monitoring and Reporting Program the turf system, the overall drainage depends heavily on the quality of the underlying base. The City may choose an artificial turf with a highly permeable base. Mitigation Measure HYD-2: Installation ofLID Measures to Improve Drainage in Detention or Low-lying Areas New detention or low-lying areas may require additional measures for drainage improvements. If the depth and the area of the low-lying areas are not adequate, underground detention facilities or additional drainage facilities would be implemented to improve drainage. Examples of drainage improvements are storm chambers, or semi-elliptical shaped barrels with drain rocks for flow dissipation. Water would be stored underground in the barrel through an inlet, and excess water comes up to the surface and is discharged through the existing storm drain system. Land Use and Planning Mitigation Measure LU -1: Seek a voluntary referral or ensure that the provisions of the CLUP are met. Prior to construction of the Athletic Center Expansion, the City will seek a voluntary referral from the Airport Land Use Commission (ALUC) regarding the design ofthe athletic center facilities. Alternatively, as a member agency of the ALUC, the City will ensure that the provisions of the Comprehensive Land Use Plan are met. Recreation Mitigation Measure REC-1: Provide Clearly Signed Detour for Pedestrians and Bicyclists A clearly signed detour for the Bay Trail and Juan Bautista de Anza NHT will be provided during closures of the Athletic Center parking lot and trail access point to maintain continuous access and to avoid confusion for trail users. Notice regarding closure and/or detour will be provided 30 days in advance. At a minimum, this notice will be provided at the trailhead, Friendship Bridge, City Hall, and on City's website. Transportation and Traffic Mitigation Measure TRA-1: Develop and Implement a Construction Traffic Control Plan Prior to issuance of grading permits, the construction contractor will develop the traffic control plan in accordance with City's policies and submit for City approval. The plan will be implemented throughout the course of Project construction and may include, but not be limited to, the following elements. Palo Alto Municipal Golf Course Reconfiguration and Baylands Athletic Center Expansion Project MMRP 23 January 2014 ICF 00631.12 City of Palo Alto Mitigation Monitoring and Reporting Program • Limit truck access to the Project site during peak commute times (7 :00 a.m. to 9:00 a.m. and 4:00 p.m. to 6:00 p.m.). • Restrict construction truck routes to truck routes designated by the cities of Palo Alto and East Palo Alto. Heavy construction vehicles will be prohibited from accessing the site from other routes. • Provide access for emergency vehicles at all times. • Provide adequate onsite parking for construction employees, site visitors, and inspectors as feasible. • Maintain bicycle/pedestrian access and circulation during Project construction where safe to do so. If construction encroaches on a bicycle lane, then warning signs will be posted that indicate bicycles and vehicles are sharing the roadway. If construction encroaches on a sidewalk, then a safe detour will be provided for pedestrians at the nearest crosswalk. • Require traffic controls in the Project area and the Project entrance driveway, including flag persons wearing bright orange or red vests and using a "Stop/Slow" paddle to control oncoming traffic. • Post standard construction warning signs in advance of the construction area and at any intersection that provides access to the construction area. • Repair or restore the road right-of-way to its original condition or better upon completion of the work. • Coordinate construction haul and delivery traffic with the affected cities to identify overlap with other area construction projects.
