7.B. - Page 50 2 Environmental Analysis <br /> Appendix C for more detail). The modeling analysis found that the average daily construction <br /> emissions would be well below the BAAQMD significance thresholds. <br /> Average Daily Emissions (lbs/day) <br /> Project Construction BAAQMD Significance <br /> Emissions Threshold for Construction <br /> Reactive Organic Gases (ROG) 1.4 54 <br /> Nitrogen Oxides (NO.) 9.8 54 <br /> PM10 (exhaust) 0.6 82 <br /> PM25 (exhaust) 0.6 54 <br /> PM10—respirable particulate matter less than 10 microns in diameter <br /> PM25—fine particulate matter less than 2.5 microns in diameter <br /> The BAAQMD considers emissions of PM10 and PM 25 less than significant if emissions from <br /> mobile sources are less than the significance levels and identifies Best Management Practices as <br /> the significance threshold for control of fugitive dust (see Appendix C). <br /> Operational Emissions. Once construction is complete, the operation of both the <br /> replacement pump station and the joint-use path would have no regular emissions of criteria or <br /> toxic pollutants, except for the testing of the emergency diesel generator up to 50 hours per year <br /> and occasional maintenance and landscaping. The estimated emissions from landscaping and <br /> maintenance and the proposed 250-kW Tier 3 diesel generator for 50 hours per year with <br /> particulate emissions of 0.13 grams/brake horsepower (bhp) hour are more than 100 times <br /> lower than the average daily and annual significance levels for ozone precursors and particulates <br /> (see Appendix C). <br /> The proposed joint-use path would enable residents of approved and proposed Bayfront <br /> development projects to have shorter, more direct non-vehicular access to the Downtown area. <br /> Residents would be able to walk or ride bicycles to jobs and retail and entertainment destinations <br /> as well as have shorter access to public transportation networks. Currently,the driving distance <br /> from One Marina to the center of Downtown is 1.5 miles. The proposed joint-use path would <br /> reduce the walking and biking distance to 0.75 miles,a 15-20 minute walk. The path would <br /> reduce the distance to the Caltrain station from 1.6 miles to 0.9 miles. <br /> Point Impact Analysis modeled the mobile source emissions from traffic at One Marina <br /> development,with and without the proposed path,using CalEEMod 211.1.1,assuming <br /> 231 residential units,three parks, a 14-acre marina, the waterfront esplanade and village walkway, <br /> 200 hotel rooms, and 10,000 square feet of retail space. The modeling shows that with the <br /> addition of the joint-use path, the improved pedestrian network and the shorter walking <br /> distances would result in at least a 2.4 percent reduction in mobile source emissions. This <br /> estimate does not take credit for future development in the Bayfront, including Pete's Harbor, or <br /> the shorter distances to destinations on Convention Way and Main Street.
