Hacienda Mixed Use Rezoning Initial Study Particulate Matter (PM 3.02 2.52 17 Carbon Monoxide (CO) 295.45 83.34 72 Carbon Dioxide (CO 21.19 28.1 33 Source: Illingworth Rodkin, using Emfac2007 V2.3 Nov. 2006, 2007. In 2005, ozone was the only pollutant for which the Bay Area was in non attainment. It is anticipated that in the future the Bay Area will be in non attainment for particulate matter. Because the proposed project is a zoning change, no construction would occur as a result of this project. At the time a development plan is considered for any of the three project sites, the City will conduct environmental analysis under CEQA to consider the potential for carbon monoxide, ozone, and particulate air quality impacts due to project construction and operation, and will identify mitigation measures, as warranted. The project site exceeds 4.0 acres. Thus an enhanced dust control program during construction would be applicable to development resulting from this project. Future development due to the zoning change may contain residential land uses, the closest of which would be about 500 feet from 1 -580. Thus any future residential development would be in compliance with the California Air Resources Board's Air Quality and Land Use Handbook: A Community Health Perpective, April 2005 and with programs contained in the Air Quality Element of the General Plan. Air quality impacts due to nearby mobile sources on residential development would be less than significant. Table 1, above, shows that greenhouse gas emissions (carbon dioxide or CO will increase in Alameda County. Table 2, below, shows the expected increase of greenhouse gas emissions in the Planning Area in the future. Although the table below considered development from this project in the cumulative total, it did not consider the reduced traffic impacts of locating high- density housing close to the BART line. Such housing would help reduce vehicle trips and trip lengths in the future. This issue will be addressed in the environmental review documents at the time development plans are proposed for the project sites.

Residential development resulting from the proposed zoning change would not generate objectionable odors; some automobile exhaust odors from on -site vehicles could be expected but would have a less th n siggruScant environmentaiiimpact.
