AUGUSTIN BERNAL MOUNTAIN BIKE TRAIL PROJECT DRAFT INITIAL STUDY <br /> 12956 <br />DUDEK 68 April 2022 <br />d) In flood hazard, tsunami, or seiche zones, would the project risk release of pollutants due to project <br />inundation? <br />Seiche and tsunami are short duration earthquake-generated water waves in large enclosed <br />bodies of water and the open ocean, respectively. The extent and severity of a seiche or tsunami <br />would be dependent upon ground motions and fault offset from nearby active faults. The project <br />site is not located adjacent to any large bodies of water and is not located downstream of a dam. <br />In addition, the project site is not located within a 100-year or 500-year flood hazard zone (FEMA <br />2021). Therefore, the project is not located within a flood hazard, tsunami, or seiche zone, and is <br />not expected to be inundated. The project would have no impact. <br />e) Would the project conflict with or obstruct implementation of a water quality control plan or <br />sustainable groundwater management plan? <br />The project would have no impact on groundwater and would therefore have no impact on a <br />groundwater management plan. As discussed above, the project would not require the use of <br />groundwater, would not interfere with groundwater recharge, and would not introduce water <br />pollutants into stormwater runoff. Therefore, the project would not adversely affect water quality or <br />groundwater supplies. The project would have no impact due to conflicting with or obstructing <br />implementation of a water quality control plan or sustainable groundwater management plan. <br />Mitigation Measures <br />See Section 3.7 for MM GEO-1 and Section 3.9 for MM HAZ-1. <br />3.11 Land Use and Planning <br /> <br />Potentially <br />Significant <br />Impact <br />Less Than <br />Significant <br />Impact With <br />Mitigation <br />Incorporated <br />Less Than <br />Significant <br />Impact No Impact <br />XI. LAND USE AND PLANNING – Would the project: <br />a) Physically divide an established <br />community? <br />b) Cause a significant environmental <br />impact due to a conflict with any land <br />use plan, policy, or regulation adopted <br />for the purpose of avoiding or mitigating <br />an environmental effect? <br /> <br />Setting <br />The project site is surrounded by existing park and recreational facilities. The majority of the trail would be <br />contained within Augustin Bernal Community Park, and a portion of the trail would cross Golden Eagle HOA <br />property, subject to an access easement. To the west, north, and south is Pleasanton Ridge Regional Park,
