Pleasanton Gateway— Environmental Checklist c) Involve other changes in the existing environment, 1 LJ LI1 which, due to their location or nature, could result in conversion of Farmland, to non - agricultural use? Discussion a -b) The proposed project is an infill development consistent with the Bernal Property Specific Plan, PUD development plan, and Development Agreement. The subject property is classified as "Urban and Built -up Land" by the California Department of Conservation. It is not covered by Williamson Land Conservation contract. No continuous agricultural activity, e.g., the cultivation of crops, orchards, etc., has taken place or is now taking place on the property that the development of this property will affect. All necessary infrastructures are available to serve the proposed development. Therefore, this would be considered no- impact. c) The proposed project will not result in the conversion of any other producing farmland in the general vicinity of the site. Therefore, this would be considered no- impact. 3. AIR QUALITY Environmental Setting The Pleasanton Gateway site is within the San Francisco Bay Area Air Basin and, therefore, under the jurisdiction of the Bay Area Air Quality Management District (BAAQMD). The Livermore - Amador Valley forms a smaller sub - regional air basin that is distinct from the larger Bay Area Air Basin, surrounded by terrain that influences both the local climate and air pollution potential. BAAQMD The Bay Area Air Quality Management District (BAAQMD) is the main permitting agency for air pollutant sources and regulates air quality in the Bay Area Region through its permit authority over most stationary emission sources and through its planning and review activities. The BAAQMD document, "California Environmental Quality Act Air Quality Guidelines" (CEQA Air Quality Guidelines), provides a guide for lead agencies and consultants on evaluating the air quality impacts of development projects for CEQA review, determining whether an impact is significant and, if significant, mitigated. On June 2, 2010, BAAQMD adopted new thresholds of significance for analyzing air quality and greenhouse gas emission impacts and published a June 2010 version of the Guidelines consistent with these adopted thresholds, which recommends screening levels and methods of analysis. ABAG Growth Assumptions A project is determined to conflict with or obstruct implementation of the regional air quality plan if it would be inconsistent with the growth assumptions derived from the Association of Bay Area Governments assumptions for population, employment, or regional growth in Vehicle Miles Traveled. These ABAG assumptions utilize the information provided in City and County General Plans. Page 20 of 52 Pleasanton Gateway Initial Study August 2, 2010
