k MOUNTAIN HOUSE NEIGHBORHOODS KAND L INITIAL STUDY 5.ENVIRONMENTAL CHECKLIST f3.AIR QUALITY AND GREENHOUSE GAS EMISSIONS i Mountain House—Neighborhoods K&L(ENVIRON,2011),which is included in this document as Appendix C. The project inventory considers GHG emissions from energy use associated with residential buildings and non-residential buildings,mobile sources,area sources, solid waste,water and wastewater, swimming pools at recreational facilities, and vegetation. Promulgated regulations that would affect the project's emissions are accounted for in this inventory. In particular,the Pavley Standards and the Renewable Portfolio Standards(RPS)would be in effect at the anticipated time of buildout of the project, and therefore are accounted for in the project emission calculations.Table 5.3-4 below presents baseline and project scenario GHG emissions, as well as the percentage reduction of the project over baseline. The project's GHG emissions, after incorporation of BPS(Mitigation Measure AIR-2)and other GHG reductions described in Appendix C, such as improved r� vehicle fuel efficiency and cleaner electricity generation (due to promulgated 1 �I regulations)would be 42,951 metric tons of carbon dioxide equivalent per year (MT CO2elyr)and the baseline GHG emissions would be 61,019 MT CO2elyr.. Therefore,the project's GHG emissions would be approximately 29.6 percent Ibelow business as usual emissions.Thus,the project would not exceed the SJVAPCD GHG threshold, and the impact would be considered less than significant after mitigation. !F t } Mitigation Measures Mitigation Measure AIR-2: The applicant shall incorporate the following Best Performance Standards(BPS)into the project design: ■ Minimization of Pedestrian Barriers. Site design and building placement shall minimize barriers to pedestrian access and interconnectivity. Physical barriers such as walls, berms, landscaping, and slopes between residential and non-residential uses that impede bicycle or pedestrian circulation shall be avoided whenever possible. Barriers to pedestrian access of neighboring facilities and sites shall be minimized. - This measure is not meant to prevent the limited use of barriers to ensure public safety by prohibiting access to hazardous areas, etc. (Credit: 1.0 percent reduction over baseline)7 ■ Neighborhood Electric Vehicle Access. Physical development shall be consistent with requirements for neighborhood electric vehicles(NEV). I Current studies show that for most trips, NEVs do not replace gas- fueled vehicles as the primary vehicle. For 1.0 percent reduction, a neighborhood shall have internal and external connections to i surrounding neighborhoods. (Credit: 1.0 percent reduction over baseline) 7 Credit is defined as an anticipated reduction applied to project GHG emissions associated with the implementation of a specified SJVAPCD BPS. i 5-43
