3.0 ENVIRONMENTAL CHECKLIST <br />1388 Bancroft Avenue Project City of San Leandro <br />Initial Study/Mitigated Negative Declaration November 2018 <br />3.0-16 <br />• The project conforms to applicable control measures from the plan and does not disrupt or hinder the implementation of any Clean Air Plan control measures. <br />The primary goals of the Clean Air Plan are compliance with the state (California) and <br />national ambient air quality standards. As discussed in checklist item b) below, the <br />project’s emissions are below all of the thresholds of significance listed in Table 2-1 of the BAAQMD’s (2017a) CEQA Guidelines for short-term construction emissions and the project meets all of the screening criteria listed in Table 3-1 of the BAAQMD’s (2017a) CEQA Air <br />Quality Guidelines for long-term operational emissions. The thresholds of significance and <br />screening criteria provide a conservative indication of whether the proposed project could result in potentially significant air quality impacts. Therefore, the project would <br />support the primary goals of the Clean Air Plan. <br />BAAQMD air quality planning control measures are developed, in part, based on the <br />emissions inventories contained in the Clean Air Plan, which are derived from projected population growth and VMT for the region. These inventories are largely based on the <br />predicted growth identified in regional and community general plans, including <br />associated development projects. Projects that result in an increase in population or <br />employment growth beyond that identified in regional or community plans could result in increases in VMT and subsequently increase mobile source emissions. As discussed in <br />subsection 3.16, Transportation/Traffic, the project would generate fewer daily trips than <br />the existing medical office buildings on the project site. In addition, the project has been evaluated for consistency with the GreenTRIP program and awarded conditional GreenTRIP certification. The GreenTRIP analysis concluded that project residents would <br />drive 33 miles per day per household, which is 34 percent less than the Bay Area regional <br />average (Rizzo 2018). Therefore, the project would not result in increased regional VMT and would not conflict with or obstruct implementation of the applicable air quality plan. This <br />impact would be less than significant. <br />b) Less Than Significant Impact with Mitigation Incorporated. <br />Short-Term Construction Period Emissions <br />The project would generate short-term criteria air pollutant and ozone precursor emissions from construction activities such as demolition, site grading, asphalt paving, building <br />construction, and architectural coatings (e.g., painting). Common sources of construction <br />emissions include fugitive dust from soil disturbance, fuel combustion from mobile heavy-duty diesel and gasoline-powered equipment, portable auxiliary equipment, and worker commute trips. During construction, fugitive dust, the predominant source of PM10 and <br />PM2.5 emissions, would be generated when wheels or blades disturb surface materials. <br />Uncontrolled dust from construction can become a nuisance and potential health hazard to those living and working nearby. Demolition can also generate fugitive dust PM10 and PM2.5 emissions. Off-road construction equipment is often diesel-powered and can be a <br />substantial source of NOx emissions, in addition to exhaust PM10 and exhaust PM2.5 emissions. Worker commute trips, material hauling trips, and architectural coatings are dominant sources of ROG emissions. Predicted unmitigated maximum daily construction- <br />generated emissions for the project are summarized in Table 3.3-4.
