Charles Jany May 19, 2011 Page 6 • Draft Traffic Impact Analysis • Phase 1 and 2 Environmental Site Assessment Shade and Shadow Analysis The applicant has provided a Shade and Shadow Analysis prepared by BDE Architecture. This study identifies potential shade and shadow impacts resulting from the project. This study would be reviewed for adequacy as it relates to fulfilling the requirements of CEQA. Air Quality and Greenhouse Gas Analysis The applicant has provided a preliminary CEQA air quality and greenhouse gas analysis. This analysis predicts air quality criteria air pollutant and greenhouse gas emissions from construction and operation of the project. Screening procedures were also used, and the analysis addresses community risk impacts associated with the proposed project. I &R would peer review the applicant's preliminary air quality and greenhouse gas analysis and provide an independent assessment of the overall approach to the study, the criteria used in the assessment, the predictive methods utilized in the analysis, and conclusions reached regarding potential air quality and greenhouse gas impacts. If necessary, a memo would be submitted summarizing our findings and a final review of the applicant's study would be made to confirm that any significant comments have been adequately addressed. Optional Task 2a: Address Potentially Significant Roadway TAC and Construction Impacts Our preliminary review of the analysis indicates potentially significant construction period impacts and potentially significant toxic air contaminant (TAC) exposure due to traffic on Veterans Boulevard. The following additional analyses are proposed as an optional task: a. The preliminary analysis was based on older, out of date, roadway screening tables that indicated potentially significant construction air quality impacts due to emissions above the Bay Area Air Quality Management District significance thresholds. Refined modeling would be conducted to verify the significance and identify mitigation measures to reduce the impacts accordingly. According to the BAAQMD screening tables for roadways, significant single- source TAC impacts may occur at portions of the project along the roadway. To address the community risk impacts posed by Veterans Boulevard traffic, we propose to conduct screening level modeling to predict cancer risk and PM2.5 exposure. This would involve developing emissions for traffic using the EMFAC model and dispersion modeling using the Cal3qhcr. Cancer risks, chronic and acute hazards and annual PM2.5 concentrations would be predicted at the project site. These levels would be compared to the BAAQMD thresholds for single source and cumulative source impacts.
