39 thresholds….” This would be a less-than-significant impact. With project component implementation of the standard BAAQMD-recommended dust control measures identified in the air quality analysis prepared as required by Focused GPU program EIR Mitigation Measure AIR-2 (above), construction and operational criteria air pollutant and toxic air contaminant emissions impacts would be less than significant. Potential for Cumulative Impacts As discussed above in Item III(b) – 1900 Broadway, impacts associated with the two project components were evaluated by Illingworth & Rodkin in a combined analysis of project component emissions for both the 1900 Broadway and the 847 Woodside Road project components (“1900 Broadway & 847 Woodside Road Combined Construction & Operational Emissions;” Memo from Illingworth & Rodkin, Inc. to Melinda Hue, City of Redwood City; June 11, 2024). The memo assessed the combined construction and operational emissions of both project components. Based on the anticipated construction schedule for 1900 Broadway to start in 2025 and end in 2028 and 847 Woodside Road to start in 2026 and end in 2028, Illingworth & Rodkin (p. 1) concluded that the two construction schedules would overlap for the years 2026 and 2027 and portions of 2028, resulting in simultaneous construction emissions. Illingworth & Rodkin used CalEEMod to estimate emissions from construction activity and operation for each project. The land use types and size, anticipated construction schedule, traffic, and other factors were input to CalEEMod for each project component as described above in Item III(b) – 1900 Broadway, and in the previous paragraphs in this item (b) – 847 Woodside Road. For construction emissions, Illingworth & Rodkin (pp. 1-2) determined that the combined construction period emissions do not exceed the BAAQMD thresholds of significance during any construction year (2025-2028). For operational emissions, Illingworth & Rodkin (p. 2) based its analysis on net increase in annual emissions and daily emissions, assuming 365 days of operation. The analysis determined that net increases in annual and daily operational emissions of ROG, NOX, total PM10, and total PM2.5 during operation of both projects would not exceed the BAAQMD thresholds of significance. The combined construction and operational impacts of both project components would be considered less than significant resulting in a less than significant cumulative impact, and no additional mitigations would be required. As noted above, the Focused GPU EIR found this impact to be significant and unavoidable with mitigation. However, as discussed previously, with project component implementation of the Focused GPU program EIR Mitigation Measure AIR-2. Therefore, the 847 Woodside project component would be consistent with the analysis of the Focused GPU EIR because it would not create new impacts or increase impacts and there is no new information of substantial importance for CEQA purposes. c. The Focused GPU program EIR (pp. 4.3-5, 4.3-7 and 4.3-8, 4.3-22 through 4.3-25) concluded that growth facilitated by the Focused GPU would result in exposure of existing and new sensitive receptors to substantial concentrations of criteria air pollutants and toxic air contaminant (TAC) emissions that could pose adverse health effects. According to the Focused GPU program EIR, the pollutants and pollutant concentrations posting substantial threats to health and property in the Bay Area Basin that were evaluated included: (1) carbon monoxide (CO) “hotspots” (known as areas of high CO concentrations such as areas where vehicular traffic exceeded the level for peak hour intersection traffic volumes), meaning that the potential CO concentrations could exceed State and/or Federal ambient air quality standards for CO; (2) construction emissions, which include particulate matter (PM10 and PM2.5) and especially diesel particulate matter (DPM), which is smaller than PM2.5 and typically comes from construction equipment exhaust; and (3) existing pollutant sources that are exacerbated by additional emissions generated as a result of new development (including such pollutants and sources as localized areas of DPM concentrations; emissions of TACs from stationary sources such as dry cleaning facilities, which emit perchloroethylene; and other pollutants such as mobile sources of benzene and 1,3-Butadiene and formaldehyde from a variety of sources). The Focused GPU program EIR also discussed the potential for operational emissions from future development facilitated by the Focused GPU to pose adverse health risks to sensitive receptors but determined that changes in the land use pattern of the city from development facilitated by the Focused GPU would “not reimagine the City in a manner that would substantially increase the quantity of highly polluting land uses (e.g., industrial facilities). Therefore, the changes in land use proposed by the Project [e.g., the Focused GPU] do not have the potential to alter the City-wide emissions profile in a manner that could exacerbate or contribute to significant health risks at or in proximity of the Planning Area” as discussed above in item (b) (Focused GPU program EIR, p. 4.3-23). The Focused GPU program EIR determined that: (1) CO Hotspots – because peak hour traffic in the city would not exceed the BAAQMD screening threshold of 44,000 ATTY/RESO.0074/CC RESO 847 WOODSIDE (CEQA) - EXHIBIT 1 - CEQA CONSISTENCY CHECKLIST REV: 10-23-24 VR Page 39 of 135
