PUD-74 Environmental Checklist BAAQMD nor any other agency has adopted significance criteria or methodologies for estimating a project's potential contribution of GHGs or evaluating its significance, if any, no individual development project, such as the proposed project, could, by itself, generate sufficient emissions of GHGs to result in a significant impact in the context of the cumulative effects of GHG emissions globally. The proposed project would also be required to meet Title 24 energy efficiency standazds and the City's Green Building Ordinance, both of which would help to reduce future energy demand. In addition, since the subject site is limited to residents aged 55 years and older, the proposed project would produce fewer vehicle trips and, therefore, fewer GHGs, than typical detached single-family home developments that are not age restricted. While these measures would not eliminate all project GHG emissions, their inclusion in the project would result in a lower GHG emissions level than had they not been incorporated into the project. It is also important to note that future state actions taken pursuant to Califomia Global Warming Solutions Act of 2006 (Assembly Bill No. 32) including requirements for lower carbon-content in motor vehicle fuels, improved vehicle mileage standards, and increased share of renewable energy in electricity generation will also serve, over time, to further reduce GHG emissions related to the proposed project. Therefore, project effects on GHG emissions would not be cumulatively considerable, are negligible, and, therefore, the cumulative effects would be less than significant. 4. BIOLOGICAL RESOURCES Environmental Setting The site had historically been farmed for several decades. Approximately 10 yeazs ago the farming ceased, and since that time the site has remained vacant except for a temporary constmction yazd with construction access road and several soil stockpiles. Therefore, the site has not supported a natural habitat component for several decades. Wetlands are regulated under federal, state and local laws, regulations and policies. Primary wetland regulatory compliance is under the Federal Clean Water Act, the Califomia Department of Fish and Game (CDFG), United States Fish and Wildlife Service (USFWS) and California Environmental Quality Act (CEQA). The Clean Water Act requires avoidance of wetlands whenever a practicable alternative exists. For unavoidable impacts, the regulatory agencies have policies calling for mitigation to provide "no net loss" of acreage or habitat value. Under Section 404 of the Clean Water Act, a permit must be obtained for the discharge of dredged or fill material into waters of the United States. Under the CDFG code, Sections 1601-1607 regulate projects with divert, obstruct, or change the natural flow, bed, channel, or bank of a river, stream, or lake. Proponents of such projects must notify DFG and enter into a streambed alteration agreement. DFG normally exerts jurisdiction over natural streams and artificial channels that have habitat value for wildlife species. The jurisdiction extends to the bank top. 13
