SAN LEANDRO SHORELINE DEVELOPMENT EIR ADDENDUM PROJECT CITY OF SAN LEANDRO TABLE 3-1 SAN LEANDRO SHORELINE DEVELOPMENT CONSTRUCTION -RELATED CRITERIA AIR POLLUTANT EMISSIONS Note: Emissions may not total to 100 percent due to rounding. BMP: Best Management Practices; NA: not applicable a. Construction phasing is based on the preliminary information provided by the City. Where specific information regarding Project -related construction activities was not available, construction assumptions were based on CalEEMod defaults, which are based on construction surveys conducted by South Coast Air Quality Management District of construction equipment and phasing for comparable projects. b. Includes implementation of best management practices for fugitive dust control required by BAAQMD as mitigation, including watering disturbed areas a minimum of two times per day, reducing speed limit to 15 miles per hour on unpaved surfaces, and street sweeping. c. Average daily emissions are based on the construction emissions divided by the total number of active construction days. The total number of construction days is estimated to be 1,041 days. Source: CalEEMod 2013.2.2. Construction emissions associated with the Original Project were found to be less than significant with mitigation. The Modified Project includes the development of residential, recreational, and retail uses in the Project Site. Construction of the modified project would generate criteria air pollutants associated with construction equipment exhaust and fugitive dust from demolition, site preparation, grading, building construction, pavement of asphalt and non -asphalt surfaces, and architectural coating over the course of 48 months. As seen on Table 3-1, construction air pollutant emissions would be less than their respective regional significance threshold values. Additionally, as discussed above, incorporation of Mitigation Measure AIR -2, as prescribed in the Certified EIR would be applicable to the Modified Project and would reduce construction -related fugitive dust impacts to less than significant levels. Overall, construction of the Modified Project would result in similar regional construction impacts as the Original Project and impacts would remain less than significant with incorporation of mitigation.
