City of Pleasanton—Additional Housing Sites Rezonings Project CEQA Guidelines Section 15164 Addendum Addendum 53 d) Fish and Wildlife Movement Corridors Would the project: Interfere substantially with the movement of any native resident or migratory fish or wildlife species or with established native resident or migratory wildlife corridors, or impede the use of native wildlife nursery sites? Summary of Prior FEIR The Prior FEIR found that the Planning Area contains important wildlife movement features and that future development could interfere with native resident or migratory wildlife movement, wildlife corridors, or wildlife nursery sites. The Prior FEIR explained that wildlife corridors link otherwise separated habitat areas and are important for population replenishment, genetic exchange, escape from disturbance, and routine movement for food, water, shelter, and mates. It further described Wildlands Overlay areas as functioning, in most cases, as corridors for wildlife movement between major open space areas, and identified specific regional linkages among Pleasanton Ridge Regional Park, the Ohlone Wilderness area, San Francisco Watershed lands, Del Valle Regional Park, and the Southeast Hills. The Arroyo de la Laguna corridor is specifically described as a valuable wildlife corridor because its riparian woodland links major habitat areas. Against that setting, the Prior FEIR concluded under BIO-12 that development under the General Plan could interfere with the movement of native resident or migratory fish or wildlife species, established wildlife corridors, or nursery sites, but that this impact would be less than significant. Proposed Project Analysis and Conclusion Consistent with the evaluation of urban sites in the Planning Area analyzed in the Prior FEIR, the proposed sites have been previously developed and are generally devoid of habitat value. Tassajara Creek is the closest wildlife corridor to any of the proposed sites and is located approximately 0.30 mile east of Site B. Additionally, Tassajara Creek is separated from the site by commercial development, lowering any project-related impacts to this corridor. However, implementation of IM BIO-1 would be required to confirm the absence of nursery sites or sensitive natural communities and provide additional mitigation as needed consistent with the requirements of General Plan Conservation and Open Space Element Program 1.6 as described above. Accordingly, with implementation of IM BIO-1 and adherence to the applicable provisions of the General Plan, project-related impacts would be reduced to less than significant levels.
