Burrowing Owl The burrowing owl is a diurnal owl that inhabits open, dry flat grassland and desert habitats of California. The owl utilizes old rodent burrows, artificial burrows, or rubble habitat for nesting and roosting, and perches for hunting and predator watch. Since the project site contains suitable burrow habitat and owls are known to occur on adjacent parcels, burrowing owls have a high potential for occurrence at the project site and could be affected by site development. Burrowing owls are protected. Alameda Whipsnake The Diablan sage-scrub community present in the southeast corner of the project site and adjacent offsite slopes provide suitable habitat for Alameda whipsnake. In addition, the lands south of the project site are undeveloped and movement corridors for this species, if present, are likely to be intact. The closest known whipsnake occurrence is approximately three miles south of the project site. The whipsnake is not likely to occur in the remaining portions of the project site due to the lack of scrub habitat and potential movement corridors. Blue Oak Woodland Community/Heritage Trees Blue oak woodland is the dominant plant community within canyons and swales on the project site and is considered to be sensitive habitat. The Lin property includes approximately 237 acres of blue oak woodland. A total of 58 Heritage- and non-Heritage and blue oak woodland size trees would be removed with the development of this site. Of these trees, 29 are classified as Heritage-size trees by the City's Heritage Tree Preservation Ordinance. Impact on the Movement of Any Species The project would not substantially interfere with the movement of native resident/migratory fish/mammal species, with established native resident/ migratory wildlife corridors for such species, or impede the use of native wildlife nursery sites. As stated previously, the project could interfere with the movement of California Tiger Salamander or California Red Legged Frog species from known onsite breeding habitat to potential breeding habitat east of the project site. Movement of these species across the extension of Hearst Drive on the project site could result in direct mortality. Mitigation Measures As conditioned, the applicant is required to retain licensed or registered biologists to prepare and submit the following biological reports/analyses and/or plans with the first final subdivision map application for review and approval by the Planning Director and the United States Fish and Wildlife Service (USFWS): A California Tiger Salamander (CTS) Mitigation and Monitoring Plan shall be prepared in consultation with the USFWS to address the potential significant impact on California tiger salamander populations due to the disturbance or removal of their upland or dispersal habitat area.
