1 4.0 Mitigation Monitoring and Reporting Program 4.1 Aesthetics allowed by the New General Plan could increase buildings heights in Downtown which could introduce new shadow effects. Mitigation Measure 4.1-1: The City shall incorporate a new policy into the New General Plan to address potential shadow impacts within the Mixed-Use Downtown area in order to mitigate shadowing impacts to adjacent shadow sensitive land uses, as described in the policy. The new policy shall be as follows: adoption of the New General Plan Carefully consider new shade, shadow, light, and glare effects from proposed development projects and comprehensive plans. The City shall incorporate a new implementation program into the New General Plan to implement the new policy in Downtown. The new program shall be as follows: Require all new development and redevelopment within the Mixed Use - Downtown land use designation to complete a shade and shadow study unless and until implementing zoning incorporates mitigation to address impacts as defined below, unless the City s Zoning Administrator determines, based on the scale and scope of the proposed project and the criteria set forth herein, that no shade and shadow study is 4-1

2 New General Plan necessary. Significant impacts shall be mitigated to the extent feasible. The following impacts will normally be considered significant: a. Introduction of landscape that would now or in the future cast substantial shadows on existing solar collectors. b. Casting of shadows covering more than 50 percent of Courthouse Square, Theatre Way, City Hall Park, Library Plaza, Hamilton Green, Depot Circle, Little River Park, Redwood Creek, or City Center Plaza 12:00 P.M. on the Spring Equinox. c. Casting of shadows that cause a solarsensitive character-defining feature (e.g. the stained-glass dome of the historic San Mateo County Courthouse building) of any historic resource to be more than 50 percent in shadow at 12:00 P.M. on the Spring Equinox. d. Casting of shadows from parcels with a higher maximum permitted height onto adjacent parcels with a lower maximum permitted height that cause solar-sensitive portions of the parcel with the lower maximum permitted height to be more than 50 percent in shadow at 12:00 P.M. on the Spring Equinox. e. Casting of shadows from parcels within the Mixed Use - Downtown area onto adjacent parcels designated Residential - Low, - Medium, - Medium High, and/or - High that cause solar sensitive portions of such residential parcels (e.g. private and common yards and balconies) to be more than 50 percent in shadow at 12:00 P.M. on the Spring Equinox. 4-2

3 New General Plan allowed by the New General Plan could increase building heights along the major transportation corridors including areas designated Mixed Use - Corridor and Mixed Use - Neighborhood and areas designated Mixed Use - Waterfront Neighborhood. The increased building heights could have the potential to introduce new shadow effects that could substantially alter the existing visual character of the areas. Mitigation Measure 4.1-2: The City shall incorporate a new policy into the New General Plan to mitigate potential shadow impacts within and around the City s major transportation corridors on adjacent shadow-sensitive land uses, as described in the policy. The new policy shall be as follows: Carefully consider new shade, shadow, light, and glare effects from proposed development projects and comprehensive plans.

Casting of shadows from parcels within the Public Facilities, Schools, and Neighborhood Commercial areas onto adjacent Low Density or Medium Density residential parcels that substantially impair the beneficial use of the Low Density or Medium Density residential parcels The increased density and intensity of urban development allowed in the plan area could introduce new sources of light and Mitigation Measure 4.1-5: The City shall incorporate a new policy and implementation program in the New General Plan to require all new development and redevelopment in the plan area to be in compliance with adoption of the New 4-6

7 New General Plan glare, specifically within Downtown, the Bayfront, and surrounding neighborhoods. Title 24 Lighting Zone (LZ-3) requirements. The policy and implementation program shall encourage the use of low mounted, downward casting exterior lighting for all new development in the plan area so as to reduce light trespass onto adjacent properties. Further, the policy and implementation program shall also require new developments to submit lighting and photometric site plans for City review and approval prior to the issuance of individual building permits. General Plan 4.2 Agricultural and Forestry Resources The project would not result in any significant agricultural or forestry resource impacts and thus no mitigation is included. 4.3 Air Quality The projected population growth allowed by the New General Plan would be inconsistent with growth projections in the current regional Clean Air Plan, in that the projected population allowed by the New General Plan would increase at a greater rate than regional projections utilized within the Clean Air Plan. There is no feasible mitigation for this impact. 4-7

8 New General Plan Although the New General Plan provides adequate buffers between new or existing sources of air pollutants (toxic air contaminants) and new or existing residences or sensitive receptors, the New General Plan does not address recent BAAQMD guidance on protecting people from the risks of TACs. Consequently, allowable development under the New General Plan may result in exposure of sensitive receptors to TACs Mitigation Measure 4.3-1: New General Plan Public Safety Element Implementation Program PS-6 shall be revised to require that the potential air quality impacts from new development projects in the City be evaluated pursuant to the applicable BAAQMD CEQA Guidelines in effect at the time the City commences the air quality evaluation, including, as applicable, the establishment of specific overlay zones around existing and planned sources as TACs. adoption of the New General Plan 4.4 Biological Resources allowed by the New General Plan could result in the loss of habitat, mortality, or indirect impacts to special status species. Mitigation Measure 4.4-1a: Modify Implementation Program NR-22 to read as follows: Program NR-22: Sensitive Biological Resources Identification. For development applications proposed for sensitive biological resource areas, require qualified biologists to identify and map all sensitive biological resources on the project site, including local, State and federally sensitive, rare, threatened and endangered plant, fish and wildlife species and their habitats; using methods and protocols in accordance with the USFWS, CDFG, and California Native Plant Society; and make recommendations for avoiding sensitive biological resources to the maximum extent feasible and pursuant to program BE-2 in Urban Form and Land Use Chapter of the Built Environment Element. These requirements shall be satisfied prior to approval of any development proposal for the site. adoption of the New General Plan 4-8

9 New General Plan Mitigation Measure 4.4-1b: Modify Implementation Program NR-23 to read as follows: Program NR-23: Mitigate Adverse Impacts of. For new development proposals in the City in which unavoidable harm or removal of sensitive biological resources could occur, require the development of a compensation plan prior to City approval of any development proposal for the site. Compensation could include purchase of mitigation credits for the affected habitat types at an established mitigation bank, or preservation and enhancement of in-kind habitat types (preferably onsite). Required compensation ratios will be developed on a case-by-case basis in consultation with U.S. Army Corps of Engineers, California of Fish and Game, San Francisco Regional Water Quality Control Board, and/or the U.S. Fish and Wildlife Service. adoption of the New General Plan Mitigation Measure 4.4-1c: Obtain Permits and Implement Conditions of State and Federal Permits for Impacts on Riparian Habitat, Wetlands, and Other Waters of the United States. Potential impacts to wetlands are regulated by the USACOE under Section 404 the CWA; CDFG under Section 1600 of the California Fish and Game Code, and San Francisco Bay RWCQB. Prior to any ground disturbing activities, and prior to the issuance of any grading or building permits within the plan area, the City shall require the project proponent to obtain all necessary permits pertaining to affected riparian habitat or Waters of the United States, including wetlands, stream channel, and open-water habitat regulated by the USACOE, CDFG, and San Francisco Bay RWQCB. Discharge of fill into Waters of the United States will require Prior to any ground disturbing activities and the issuance of a grading or building permit within the plan area 4-9

10 New General Plan a CWA Section 404 permit from the USACOE and CWA Section 401 certification from the San Francisco Bay RWQCB. The permitting process will also require compensation for impacts to wetlands allowed by the New General Plan could result in the loss of habitat, mortality or indirect impacts to special status plant species. Mitigation Measure 4.4-2a: Avoid Impacts to Special Status Plants. The loss of special status plants should be avoided or reduced to the extent feasible for each project site associated with a sensitive biological resource area. Prior to consideration of any development or public improvement proposal for the site, the project proponent shall retain a qualified botanist approved by the City to conduct a special-status plant survey, according to protocols established by the CNPS, CDFG, or the USFWS, to identify and map special status plants and make recommendations for avoiding or mitigating impacts to all special status plants on the project site. The botanist will coordinate placement of protective temporary fencing outside of special status plant populations to be preserved. of field surveys and fencing should correspond with the blooming period when target species are most conspicuous and easily recognizable. consideration of any development or public improvement proposal within the plan area Mitigation Measure 4.4-2b: Compensate for Loss of Special Status Plants. For each project that removes special status plants, the City shall require the development of a compensation plan, including compensation for impacts to special status plant species through preservation, enhancement, and/or restoration of habitat to assist in the recovery of the species. The City shall require that any such compensation plans are incorporated in project plans and conditions of project approval. Prior to any project approval within the plan area 4-10

11 New General Plan Prior to construction, individual special status plant species within the work areas that may be impacted shall be enumerated, photographed, and conspicuously flagged to maximize avoidance, as well as to determine the total number of individuals affected. Seed collection from individuals with mature seed that are likely to be impacted should be collected and properly stored for postconstruction propagation and re-establishment. The first six inches of topsoil within occupied habitat should be stored separately on site and protected from exotic weeds seed dispersal for the purpose of returning this soil horizon to its appropriate place in the profile in an attempt to salvage any viable seeds in the seed bank allowed by the New General Plan could result in the loss of habitat, mortality or indirect impacts to special status animal species. Mitigation Measure 4.4-3a: Consult with USFWS if Federally-Protected Species or Habitats are Identified. If habitats that potentially support special status species are found within or adjacent to a project area, the project proponent must consult with the USFWS under Section 7 of the federal Endangered Species Act (or Section 10 if the project involves a federal action) and obtain all required federal permits and approvals and comply with all applicable federal requirements. Prior to any project approval within the plan area Mitigation Measure 4.4-3b: Consult with CDFG if Habitats Potentially Supporting Southwestern Pond Turtle are Identified. If aquatic habitats, riparian habitats, ponds, canals, creeks, or other drainages or water bodies with adjacent upland habitats that potentially support southwestern pond turtle are found in a project area, the City shall require that the project proponent avoid these habitat areas to the extent practicable, and implement mitigation required by the CDFG. Prior to any project approval within the plan area 4-11

12 New General Plan Mitigation Measure 4.4-3c: Avoid Impacts on Active Burrowing Owl Nesting and Wintering Burrows. If active burrowing owl nesting or wintering burrows are found on or in the vicinity of a project area, the project proponent will implement mitigation strategies to avoid, reduce or mitigate impacts to burrowing owls, as required by the CDFG. Prior to any project approval within the plan area Mitigation Measure 4.4-3d: Compensate for Impacts to Habitat for Special status species. The City shall require compensation for impacts to special status species habitat through preservation, enhancement, and/or restoration of habitat or assist in the recovery of the species.

Mitigation Measure 4.4-4a: Avoid Impacts on Active Nest for Special Status Avian Species. If nests for special status avian species are found on or in the vicinity of a project area, or if there are potential effects related to the loss of foraging habitat on nesting raptors, the project proponent will consult with the CDFG to develop appropriate site-specific mitigation strategies to avoid impacts on active nests and rookeries. Mitigation measures may include establishing protective nondisturbance buffer zones, timing restrictions, or compensation through acquisition of replacement nesting habitat. t Prior to project approval and on-going through project operation within the plan area 4-12

13 New General Plan Mitigation Measure 4.4-4b: Avoid Impacts to Active Migratory Bird Nests. If active migratory bird nests are found on or in the vicinity of a project area, the project proponent shall consult with the USFWS Migratory Bird Permit Office and the CDFG to develop appropriate sitespecific mitigation strategies to avoid impacts on active nests. Mitigation measures may include establishing protective non-disturbance buffer zones, timing restrictions, and monitoring restrictions. The City shall require that project plans and conditions of approval incorporate mitigation acceptable to the USFWS and/or the CDFG. Prior to project approval and on-going through project operation within the plan area allowed by the New General Plan could result in the loss or disturbance to active bat roosts and habitat of special status bat species. Mitigation Measure 4.4-5a: Avoid Impacts to Active Bat Roosts. If active bat roosts are found on or in the vicinity of a project area, the project proponent will consult with the CDFG to develop and implement site-specific mitigation strategies to avoid impacts on active roosts, if feasible. Active bat roosts are protected under the California Fish and Game Code, Section 4150 (non-game mammals) and under CEQA. Mitigation measures may include establishing protective non-disturbance buffer zones, timing restrictions, and exclusion devices implemented prior to or after the maternity season. Prior to project approval and on-going through project operation within the plan area Mitigation Measure 4.4-5b: Compensate for Impacts to Active Bat Roosts and Habitat of Special Status Bat Species. When impacts to active bat roosts cannot be feasibly avoided, the City shall require compensation for impacts to bat roosts and habitat of special status bat species through preservation, enhancement, and/or restoration of habitat or assist in the recovery of the species. The City shall require that project plans and conditions of approval incorporate mitigation acceptable to the CDFG. Prior to any project approval within the plan area 4-13

14 New General Plan allowed by the New General Plan could result in the potential spread of invasive weeds in the hillsides, creekside and waterfront areas. Mitigation Measure 4.4-6a: Identify Invasive Weeds in Proposed Project Area. Prior to consideration of any development proposal where the City finds evidence of the presence of invasive weeds, the City will require a botanist to identify and map the invasive weed populations on the proposed development site prior to construction activities. Invasive weeds are defined as those species rated as A, B, or C by California of Food and Agriculture or rated High Threat by the California Invasive Plant Council. consideration of any development proposal within the plan area Mitigation Measure 4.4-6b: Monitor and Control Invasive Weeds in Proposed Project Area. After construction, sites will be monitored to detect the spread or establishment of new populations of invasive non-native weed populations. On-going 4.5 Cultural Resources Construction activities, including site preparation and grading, associated with new development allowed under the New General Plan could adversely impact previously undiscovered archaeological resources due to uncovering or unearthing these resources. Mitigation Measure 4.5-1a: approval of any ground-disturbing activities in the City s jurisdiction under the New General Plan, the City shall adopt a resolution approving a standard condition of approval on all ground-disturbing activities, which condition shall require all of the following: (a) Work stoppage in the event sensitive cultural resources are identified. Specifically, if deposits of prehistoric or historic archeological materials are encountered during project construction activities, all work within an appropriate buffer area around the discovery shall be stopped and a approval of any grading permit; ongoing through grading and construction activities. 4-14

15 New General Plan qualified archeologist meeting federal criteria under 36 CFR 61 shall be contacted to assess the deposit(s) and make recommendations. (b) If deposits of prehistoric or historic archeological materials cannot be avoided by project activities, the City shall confirm that the project applicant(s) have retained a qualified archaeologist to evaluate the potential historic significance of the resource(s). If the deposits are determined to be nonsignificant by a qualified archeologist, avoidance is not necessary. If the deposits are determined to be significant by the qualified archeologist, the resources shall be avoided if feasible. If avoidance is not feasible, project impacts shall be mitigated in accordance with the recommendations of the qualified archaeologist, in coordination with the City and CEQA Guidelines Section (b)(3)(c), which requires implementation of a data recovery plan. The data recovery plan shall include provisions for adequately recovering all scientifically consequential information from and about any discovered archeological materials and include recommendations for the treatment of these resources. In-place preservation of the archeological resource is the preferred manner of mitigating potential impacts, as it maintains the relationship between the resource and the archeological context. Inplace preservation also reduces the potential for conflicts with the religious or cultural values of groups associated with the resource. Other mitigation options include, but are not limited to, the full or partial removal and curation of the resource. The City shall confirm that the project applicant(s) have retained a qualified 4-15

16 New General Plan archeologist for the preparation and implementation of the data recovery plan, which shall be conducted by prior to any additional earth-moving activities in the area of the resource. The recovery plan shall be submitted to the project applicant, the City, and the NWIC. Once the recovery plan is reviewed and approved by the City and any appropriate resource recovery completed, project construction activity within the area of the find may resume. A data recovery plan shall not be required for resources that have been deemed by the NWIC as adequately recorded and recovered by studies already completed. Mitigation Measure 4.5-1b: issuance of grading permits within the plan area, the City shall confirm that any development applicant has required all construction crews to undergo adequate training for the identification of federal or state-eligible cultural resources, and that the construction crews are aware of the potential for previously undiscovered archaeological resources within the plan area, of the laws protecting these resources and associated penalties, and of the procedures to follow should they discover cultural resources during projectrelated work. To the extent that individual development projects are found to have the potential to disturb or destroy archaeological resources, subsequent environmental documentation may be required, including mitigation measures to address any identified significant impacts. issuance of a grading permit within the plan area 4-16

17 New General Plan Earth moving activities, particularly deep grading, associated with the construction of new development allowed under the New General Plan could have the potential to destroy paleontological resources. Mitigation Measure 4.5-2: approval of any ground-disturbing activities in the City s jurisdiction under the New General Plan, the City shall adopt a resolution approving: As a standard condition of approval on all ground-disturbing activities, which condition shall require all of the following: (a) Work stoppage in the event sensitive paleontological resources are identified. Specifically, prior to the issuance of grading or demolition permits, the City, in consultation with a qualified paleontologist, shall assess individual development project proposals within the plan area for the potential to destroy unique paleontological resources. The City Housing and shall require development proposals entailing significant earthworks or deep foundations with the potential to penetrate sedimentary rock layers to incorporate a study by a professional paleontologist to assess the potential for damage of paleontological resources. Should the paleontologist determine that the proposal has the potential to damage resources, the study shall include detailed provisions for the protection of these resources to the City. These provisions may include the complete avoidance of the resource, in-place preservation, and/or complete data recovery as discussed in Mitigation Measure 4.5-1a. approval of any grading permit; ongoing through grading and construction activities Ground-disturbing activities associated with construction of new development allowed under the New General Plan could impact previously undiscovered Mitigation Measure 4.5-3a: For future development projects permitted by the City under the New General Plan, if human remains are encountered during grounddisturbing activities within specific project sites, the project contractor and/or on-site supervisor shall provide approval of any grading permit; ongoing 4-17

18 New General Plan human remains. certification to City that work within 50 feet of the discovery is stopped. The project contractor shall immediately notify the San Mateo County Coroner (Coroner) upon the discovery of any human remains. At the same time, a qualified archaeologist meeting federal criteria under 36 CFR 61 shall be contacted by the project applicant(s) and project contractor, in coordination with the City to assess the situation and consult with the appropriate agencies. If the human remains are of Native American origin, the Coroner shall notify the NAHC within 24 hours of this identification. The NAHC will identify a Most Likely Descendant (MLD) to inspect the site and provide recommendations for the proper treatment or disposition, with proper dignity, of the remains and any associated grave goods. Upon completion of the assessment, the qualified archaeologist shall prepare a report documenting the background to the finds, and providing recommendations for the treatment of the human remains and any associated cultural materials, as appropriate and in coordination with the recommendations of the MLD. The report shall be submitted to the project applicant, the City Planning, and the NWIC. Once the report is reviewed and approved by the City Planning, and any appropriate treatment completed, project construction activity within the area of the find may resume. through grading and construction activities. If the MLD does not make recommendations within 48 hours the project applicant(s) shall reinter the remains in an area of the property secure from further disturbance. If the project applicant(s) does not accept the MLD s recommendations, the applicant(s) or the MLD may request mediation by the NAHC. 4-18

19 New General Plan Mitigation Measure 4.5-3b: issuance of grading permits within the plan area, the City shall confirm that any development applicant has required all construction crews to undergo a training session to inform them of the presence and nature of federal or state-eligible cultural resources and the potential for previously undiscovered archaeological resources and human remains within the project area, of the laws protecting these resources and associated penalties, and of the procedures to follow should they discover cultural resources during project-related work. issuance of a grading permit within the plan area 4.6 Geology and Soils The plan area is subject to a number of potential seismic hazards, including ground shaking, landslides, liquefaction, and lateral spreading that would affect future development allowed under the New General Plan. Mitigation Measure 4.6-1: On sites where threats from seismic hazards cannot be adequately mitigated through the application of existing regulatory requirements and New General Plan policies and implementation programs, the City shall use open space easements and/or other related regulatory measures to limit development and thus avoid public safety hazards. Ongoing 4.7 Hazards and Hazardous Materials The project would not result in any significant hazard or hazardous material impacts and thus no mitigation is included. 4.8 Hydrology and Water Quality The project would not result in any significant hydrology and water quality impacts and thus no mitigation is included. 4.9 Land Use and Planning The project would not result in any significant land use impacts and thus no mitigation is included. 4-19

20 New General Plan 4.10 Noise and Vibration Ground vibration levels resulting from railroad train operations at the setback of proposed residences could exceed appropriate vibration thresholds and could expose people to groundborne vibration. Mitigation Measure : The City shall revise the New General Plan to include a new or revised policy and implementation program that requires vibration-sensitive buildings (including but not limited to residential buildings) to be sited at least 100 feet from the centerline of railroad tracks, whenever feasible. The policy and implementation program shall also require the preparation of a site-specific vibration study for any residential or vibration-sensitive development proposed within 100 feet of the centerline of the railroad tracks. The study shall include recommended measures to reduce vibration to meet City-wide vibration standards, as defined per Program PS-65 of the New General Plan. Potential measures to reduce vibration include, but are not limited to, modifications in site planning or building construction. The City shall include the recommendation(s) of site-specific vibration studies as conditions of any subsequent project approvals involving potentially significant vibration impacts. adoption of the New General Plan Aircraft noise over proposed areas where residential use would be allowed under the New General Plan would exceed City noise thresholds, which could expose individuals living and working within the plan area to excessive noise levels. Mitigation Measure : The City shall revise New General Plan Policy PS-14.2 to include a threshold for noise impact mitigation for development within the identified aircraft noise contours. The revision shall be as follows: Policy PS-14.2: Require that proposed land use policy actions (such as a General Plan Amendment, zoning amendment, or a Precise Plan) within the identified aircraft noise contours for San Carlos Airport are: adoption of the New General Plan Reviewed by the Airport Land Use Commission (C/CAG Board) 4-20

21 New General Plan Mitigated for potential noise impacts, as appropriate to applicable City noise standards, by the developer; Consistent with the Aircraft Noise/Land Use Compatibility Standards in the San Mateo County Airport Land Use Plan Population and Housing Adoption of the New General Plan would allow development of up to 9,103 additional dwelling units in the plan area and potentially create 28,002 jobs, which would directly and/or indirectly induce population growth. Mitigation Measure : Modify Program BE-22 to read as follows: Program BE-22: New and Available Water Resources Tracking. Track the number of new residential units and non-residential development and limit new development to available water resources. adoption of the New General Plan 4.12 Public Services The project would not result in any significant public services impacts and thus no mitigation is included Recreation, Parks, and Open Space The project would not result in any significant recreation, parks, and open space impacts and thus no mitigation is included Transportation New development allowed under the New General Plan could cause an increase in traffic that is substantial in relation to the existing traffic load and capacity of the roadway system and result in unacceptable service levels on some roadway segments based on current LOS policy. There is no feasible mitigation for this impact. 4-21

22 New General Plan The reduction of the number and/or width of travel lanes along specified roadway segments ( pedestrian enhancement design ) would result in an unacceptable service level at one of the proposed locations. Mitigation : The City shall revise Program BE-52 of the New General Plan to the following: Program BE-52: Pedestrian Enhanced Design (PED) Criteria. Establish criteria to identify roadways for implementing pedestrian enhanced design. Conduct engineering studies to determine feasibility of implementing PEDs that provide multi-modal amenities within the public right-of-way by reducing the number and/or width of travel lanes on the following streets that are projected to have excess vehicle capacity: adoption of the New General Plan Veterans Boulevard (from 6 lanes to 4 lanes east of Brewster Avenue) Middlefield Road east of Woodside Road (from 4 or 5 lanes to 3 lanes) Jefferson Avenue between Hudson Street and Alameda de Las Pulgas and between Marshall Street and Veterans Boulevard (from 4 lanes to 3 lanes), and potentially between Hudson Street and Clinton Street if traffic signals on El Camino Real can be appropriately timed to accommodate it. Broadway between Maple Street and a quarter-mile east of Douglas Avenue where Broadway already provides a three lane cross-section (from 4 lanes to 3 lanes) Brewster Avenue from El Camino Real and Elwood Street (from 4 lanes to 3 lanes) 4-22

23 New General Plan 4.15 Utilities allowed by the New General Plan could generate an increase in future demand for water supply that is not anticipated to be fully met by the City s existing and future water supplies. See Mitigation Measure There is no feasible mitigation for this impact Greenhouse Gas Emissions The New General Plan would allow for new development to occur in areas that may be subjected to tidal inundation if sea level rises; this could place additional people and structures at elevated risk of exposure to flood hazards associated with long-term sea level rise. There is no feasible mitigation for this impact Energy The project would not result in any significant energy impacts and thus no mitigation is included. Source: CirclePoint,
