City of San Leandro <br />Housing Element Update (2015-2023) Project <br />Initial Study and Environmental Checklist <br />Less Than <br />Significant <br />Potentially With <br />III. AIR QUALITY <br />Significant Mitigation Less Than No <br />Would the project: Impact Incorporated Significant Impact <br />b) Violate any air quality standard or contribute substantially to <br />❑ <br />❑ <br />® <br />❑ <br />an existing or projected air quality violation? <br />c) Result in a cumulatively considerable net increase of any crite- <br />ria pollutant for which the project area is in non -attainment <br />under applicable federal or State ambient air quality standards <br />❑ <br />❑ <br />® <br />❑ <br />(including releasing emissions which exceed quantitative <br />thresholds for ozone precursors)? <br />d) Expose sensitive receptors to substantial pollutant concentra- <br />❑ <br />❑ <br />® <br />❑ <br />tions? <br />e) Create objectionable odors affecting a substantial number of <br />❑ <br />❑ <br />❑ <br />people? <br />a) Mould the project conflict with or obstruct implementation of the applicable air quality plan? <br />The Bay Area Air Quality Management District (BAAQMD) is the regional air quality agency for the San <br />Francisco Bay Area Air Basin (SFBAAB), which comprises all of Alameda, Contra Costa, Marin, Napa, San <br />Francisco, San Mateo, and Santa Clara Counties; the southern portion of Sonoma County; and the south- <br />western portion of Solano County. Accordingly, the City is subject to the rules and regulations imposed by <br />BAAQMD, as well as the California ambient air quality standards adopted by the California Air Resources <br />Board (CARB), and national ambient air quality standards adopted by the United States Environmental Pro- <br />tection Agency (USEPA). The applicable air quality plan is the 2010 Bay Area Clean Air Plan. <br />Implementation of the Housing Element is not anticipated to result in potential future development that <br />would meet or exceed the current BAAQMD standards for air quality impacts given the level of development <br />accommodated by the Housing Element is consistent with the 2013 projections prepared by the ABAG, <br />which in turn guide the Bay Area Air Quality Management District's air quality planning programs. <br />Given the proposed Project is consistent with the adopted 2010 Bay Area Clean Air Plan and compliance <br />with applicable and mandatory regulation (i.e. CEQA, BAAQMD thresholds), potential future development <br />that could occur under the proposed Project would have no impactwith respect to air quality. <br />b) Would the project violate any air quality standard or contribute substantially to an existing orprojected air quality viola - <br />lion? <br />San Leandro meets federal ambient air quality standards, except national standards for ozone and state stand- <br />ards for ozone, coarse inhalable particulate matter (PM1o), and fine inhalable particulate matter (PM2.5). How- <br />ever, the state ambient standards of ozone, PM1o, and PM2.5 are regularly exceeded (CARB, 2011). <br />General Plan Policy 31.04, Design, Construction, and Operation, requires construction and grading practices <br />that minimize airborne dust and particulate matter. In addition, potential future housing would be required to <br />comply with General Plan policies related to air quality and with Zoning Code requirements regarding odor, <br />conform to the 2010 Bay Area Clean Air Plan, and meet National Ambient Air Quality Standards (NAAQS) <br />and BAAQMD thresholds during both construction and operation activities. <br />Page 118 <br />
