CITY OF SAN LEANDRO RE: Exhibit A -CONSISTENCY MEMORANDUM FOR THE SLTC MIXED-USE PROJECT (PLN16-oo67) JULY 2.7, 2017 Paqe 18 Construction and Air Quality Impacts Construction activities would produce combustion emissionsfrom various sources, such as on-site heavy- duty construction vehicles, vehicles hauling materials to and from the site, and motor vehicles transporting the construction crew. Site preparation activities would produce fugitive dust emissions (PMio and PM2s) from demolition and soil -disturbing activities, such as grading and excavation. Air pollutant emissions from construction activities on-site would vary daily as construction activity levels change. Construction activities associated with the proposed projectwould result in emissions of reactive organic gases (ROG), nitrogen oxides (NOx), carbon monoxide (CO), and PM o and PM:.S. To determine potential construction -related air quality impacts, criteria air pollutants generated by project -related construction activities for the entire Scenario 3 are compared to the BAAQMD significance thresholds. Average daily emissions are based on the annual construction emissions divided by the total number of active construction days. As outlined in Table 5, criteria air pollutant emissions from construction equipment exhaust would not exceed the BAAQMD average daily thresholds.

Mitigation Mitigation Measures Measures Exceed BAAQMD Threshold? No No No No No No Source: CalEEMod version 2016.3.1. See AppendixA for emission model outputs. As shown in Table 4 above, projected emissions for the full SLTC would fall below the construction - related significance thresholds developed by the Bay Area Air Quality Management District (BAAQMD), the air pollution control officerfor the region. Therefore, as the project represents only a fraction of SLTC buildout, project emissions would also fall below BAAQMD thresholds. The project would not exceed the buildout proposed in the TOD Strategy and analyzed in the TOD Strategy EIR. The TOD Strategy EIR found that construction -related criteria pollutant emissions from exhaust associated with TOD Strategy buildout would be less than significant. Thus, no further analysis is needed, and the project is consistent with the City's TOD Strategy EIR.
