Cartleridge Trailhead Addendum As indicated in the biological assessment, the oak woodland is dense and well-developed within the properties that comprise the Pleasanton Ridge Regional Park, but is not as dense on the subject property. The biological assessment for the Meadowlark Development evaluated the possibility of special- status plant species (those listed as Endangered, Threatened, Rare, or species proposed by listing by the U.S. Fish and Wildlife Service (USFWS), the California Department of Fish and Wildlife (DFW), and the California Native Plant Society (CNPS)), and the possibility of special-status animal species (those listed by the USFWS under the Endangered Species Act and by the DFW under the California Endangered Species Act). Of the 29 special-status plant species that have at least some potential to occur within the region or have been recorded historically in the project vicinity, 17 are not expected to occur on the site because no suitable habitat is available, or the project site is not within their range. While the remaining 12 species have some potential to occur within the study area, the assessment concluded the likelihood of their existence was low due to the lack of quality habitat. Of the 23 special-status animal species that have at least some potential to occur within the region or have been recorded historically in the project vicinity, 5 species are not expected to occur on the project site due to the absence of suitable habitat, or because the subject site is outside the known range of the species, 17 species have a low potential to occur on the site, and one species has only a moderate potential to occur on the site. Therefore, the biological assessment concluded there are no known endangered, threatened, or rare species of flora or fauna known to inhabit the project site, nor is the site considered to be habitat area for said species. The proposed parking and circulation improvements would have minimal impacts on these biological resources because these facilities would be located within or adjacent to the existing roadway, an area of minimal ecological sensitivity. As noted above, the wetlands on the site are located approximately 350 feet to the south of the proposed trailhead and would not be adversely affected by associated development activities. In addition, the proposed restroom and water fountain facilities have been designed to minimize grading, site disturbance, and vegetation removal. No wetlands,creeks, swales, significant trees,or other sensitive plant/animal communities would be adversely affected by the project. 5.5. CULTURAL RESOURCES The footprint of the proposed trailhead consists of former grazing land and contains no identified cultural resources. Similar to the project analyzed in the IS/MND, if archaeological resources or human remains are discovered during grading, trenching, or other site improvement work, the City will require an archaeologist to evaluate the finds and establish additional protective measures, as warranted. Therefore, any impacts to previously unidentified cultural resources would be reduced to a less-than-significant level. 5.6. GEOLOGY AND SOILS The proposed circulation, site improvements, and grading may slightly accelerate natural erosion in and around the project site. However, the scope of the project is deliberately designed to have June 9,2016 11
