<br />;7~ - /4 <br /> <br /> <br />Potentially Significant <br />Unless Mitigation <br />Inco oration <br /> <br />c) <br /> <br />Involve other changes in the existing environment which, due to their location <br />or nature, could result in conversion of Farmland, to non-agricultural use? <br /> <br />Currently, a commercial nursery and several multi-family residential units <br />occupy the site. There are no current or planned agricultural activities in the <br />project area. See all responses to items II.(a) and II. (b). <br /> <br />x <br /> <br /> <br />a) <br /> <br />Conflict with or obstruct implementation of the applicable air quality plan? <br /> <br />The project would not conflict with or obstruct implementation of any air <br />quality attainment plan established by the California Air Resources Board, the <br />Bay Area Air Quality Management District (BAAQMD) or the Federal <br />Environmental Protection Agency (EPA). <br /> <br />x <br /> <br />b) Violate any air quality standard or contribute substantially to an existing or <br />projected air quality violation? <br /> <br />The project would not violate any air quality standard or contribute <br />substantially to an existing or projected air quality violation. <br /> <br />x <br /> <br />c) <br /> <br />Result in a cumulatively considerable net increase of any criteria pollutant for <br />which the project region is non-attainment under an applicable federal or state <br />ambient air quality standard (including releasing emissions that exceed <br />quantitative threshold for ozone precursors)? <br /> <br />There would be no direct air emissions associated with the re-zoning of the <br />existing parcels. Because the operational activities would not result in direct <br />air emissions, no permits would be requiredfrom BAAQMD for the proposed <br />project and no mitigation is necessary. <br /> <br />x <br /> <br />d) Expose sensitive receptors to substantial pollutant concentrations? <br /> <br />Although the re-zoning of the existing parcels would not directly result in the <br />production of substantial pollutant concentrations, it may result in the City <br />requiring additional street and right-of-way improvements (such as street <br />trees along Woodside Road and/or curb and gutter improvements to Lucerne <br />Avenue) that may result in minor construction activities. These related <br />construction activities would generate fugitive dust. Excavation and fill <br />activities associated with the improvements would entail earth disturbance <br />and potential dust generation. These activities could result in localized dust <br />nuisances near the construction activity. The largest dust particles would be <br />expected to settle out very close to the construction site, but some quantities of <br />dust would be windborne beyond the construction site toward adjacent land <br />uses. There is a slightly increased health risk from breathing such benign dust <br />due to small amounts of active micro-organisms in soil, but the risk factor is <br />considered low. <br /> <br />Project construction would also result in increased levels of equipment <br />exhaust emissions (nitrogen oxides), and to a lesser extent carbon monoxide, <br />sulfur dioxide, and hydrocarbons or reactive organic gases (ROG). <br />Construction employee vehicles and on-site use of pick-up trucks and small <br />vehicles would also result in air pollutant emissions, but the levels would be <br />negligible compared to emissions from on-site heavy equipment andfrom off- <br />site trucks. Equipment exhaust contains both pulmonary irritants as well as <br /> <br />x <br /> <br />5 <br />
