Significant Impact Impact 4.3-2: The project would result in the loss of habitat for the California tiger salamander and individual California tiger salamanders may be taken during construction of the project. Finding Changes or alterations have been required in, or incorporated into,the project which mitigate or avoid the significant effects on the environment. Facts in Support of Finding The City of Pleasanton has adopted the following measures which will reduce potential impacts to California tiger salamander to a less-than-significant level: Mitigation Measure 4.3-2a: To mitigate for the loss of aestivation habitat and potential impacts to any aestivating California Tiger Salamander(CTS)on-site, the project applicant shall permanently preserve and manage potential CTS upland aestivation habitat located on the project site between the proposed development area and Pond 2, located on the adjacent Oak Grove property. The amount of such preserved and managed habitat shall be not less than the amount of land developed as a result of project construction (i.e., 1:1 acreage ratio). The applicant shall preserve such habitat through the recording of a deed restriction, conservation easement, or other equivalent instrument which precludes future development or the construction of physical barriers to the movement of CTS across the preserved habitat. The applicant shall also develop, and arrange for the implementation of a habitat management plan for the preserved habitat. Prior to the issuance of a grading permit, the applicant shall provide a copy of the recorded instrument(which will identify the precise size and location of the permanently preserved habitat),the habitat management plan and the federal and state take authorizations to the City. The applicant shall also provide copies of the incidental take authorizations secured for the project from the USFWS and CDFW to the City. Mitigation Measure 4.3-2b: To avoid and minimize the loss of individual California Tiger Salamander (CTS), the applicant shall be responsible for implementing the following measures prior to and during construction: • Prior to ground disturbance, an employee training program for operators/contractors shall be conducted by a qualified biologist to explain the endangered species concerns at the project site; • Site grading shall be conducted outside of the rainy season months during which CTS would be breeding or migrating; • A qualified biologist shall conduct a preconstruction survey prior to the onset of site grading. All suitable habitat features that may be used by aestivating CTS shall be identified,marked and mapped during the preconstruction survey. The removal or destruction of suitable habitat features shall be conducted under the direct supervision of the qualified biologist prior to the onset of site grading. Any observed CTS shall be turned over to the USFWS or CDFW personnel for relocation, or shall be relocated by a biologist possessing an Endangered Species Act l0(a)(1)(A)permit as directed by the USFWS and CDFW; • Best Management Practices shall also be implemented to minimize the potential mortality, injury or other impacts to CTS. Any installed erosion control materials shall not include small-mesh plastic netting. All trash items shall be removed from the project site to reduce the potential for attracting predators of CTS, such as crows and ravens. LUND RANCH II(PUD-25)RESIDENTIAL,PROJECT 6 FINDINGS
