of 0.3 μg/m3, and the BAAQMD single-source annual HI (“hazard index”) significance threshold of 1.0. Because none of these health risk categories exceeds their respective thresholds of significance, this would be a less- than-significant impact, and health risk reduction measures in Mitigation Measure AQ-3a would not be required and no additional mitigation would be required. Potential for Cumulative Impacts Illingworth & Rodkin (pp. 31-34) evaluated cumulative health risks due to the project component location and proximity to existing permitted stationary TAC sources and existing sensitive receptors. Illingworth & Rodkin identified existing health risks from nearby roadway and stationary sources, using BAAQMD geographic information systems screening maps, and 14 existing stationary sources of TACs identified with the potential to affect the project MEI. According to BAAQMD Permitted Stationary Source 2021 GIS data, the 14 existing sources identified within a 1,000-foot radius of the project component site include 10 as being listed for having a diesel-powered emergency generator, two identified as gas-dispensing facilities, and two treated as a “generic case” for conservative risk screening because no data were available. Based on BAAQMD screening data estimates, the results of the Illingworth & Rodkin analysis (pp. 31-34) determined that while the project’s unmitigated construction maximum cancer risk, annual PM2.5 concentration, and HI would not exceed the BAAQMD single-source thresholds, the combined sources maximum annual PM2.5 concentration would exceed BAAQMD cumulative source thresholds “…due to the MEI’s proximity to Facility ID #15544” (Illingworth & Rodkin, p. 33), which contributes “[o]ver 96 percent of the total annual PM2.5 concentration at the MEI....” Illingworth & Rodkin (p. 34) determined that the project contribution to the cumulative risk totals is not cumulatively considerable. Because the project would not make a considerable contribution to a cumulative health risk impact, the cumulative health risk impact of the project components would be considered less than significant, and no additional mitigations would be required. As previously discussed, the EIR found this impact to be less than significant, but the SEIR found it to be less than significant with mitigation. Implementation of DTPP Plan-Wide Amendments program SEIR Mitigation Measure AQ-3a would reduce project component exposure of sensitive receptors to substantial pollutant concentrations to a less-than-significant level. Therefore, the 1900 Broadway project component would be consistent with the analysis within the EIR/SEIR because it would not create new impacts or increase impacts, and there is no new information of substantial importance for CEQA purposes. d. The DTPP program EIR (p. 12-21) concluded that development facilitated by the DTPP could result in food service uses in close proximity or in the same building as other odor-sensitive uses, which would be reduced to a less than significant level with mitigation. Mitigation Measure 12-2 for projects with food service businesses requires implementation of odor-reducing measures consistent with the BAAQMD CEQA Air Quality Guidelines and DTPP regulation 2.2.2.1.e. These would include, for example, integral grease filtration or grease removal systems, baffle filters, activated carbon filters, oxidizing pellet beds, and exhaust stack and ventilation location with respect to receptors, subject to City review and approval. The DTPP Plan-Wide Amendments program SEIR (p. 12-44 through 12-45) generally concurred with the DTPP EIR conclusion but explained that Mitigation Measure 12-2 is no longer necessary because of the requirements of BAAQMD Rule 6-2 (Commercial Cooking Equipment). The DTPP Plan-Wide Amendments program SEIR concluded that projects would not be expected to generate odors adversely affecting a substantial number of people;, the impact would be less than significant, and no mitigation measures would be required. The project component plans include a retail dining use on the Broadway side adjacent to and east of the public common area, although no additional details are provided at this time beyond an estimated approximately 12,060 square feet of space reserved for the use (Plan Sheet A2, 11/9/23; Sandis, “Utility Report, 1900 Broadway, Redwood City, California, 94063,” Attachment “F” Proposed Domestic Water Demand Worksheet (City Attachment Q), September 2023). (See item “c” for discussion of health risks and sensitive receptors.) Any commercial cooking equipment for future food service uses would be required to meet the requirements of BAAQMD Rule 6-2 as applicable and no mitigation measures would be required. The 1900 Broadway project component would be consistent with the analysis of the EIR/SEIR because it would not create new impacts or increase impacts, and there is no new information of substantial importance for CEQA purposes. CONCLUSION With regards to the issue area of Air Quality, the following findings can be made: (1) no peculiar impacts to the 1900 Broadway project component or its site have been identified, (2) there are no potentially significant effects or off-site ATTY/RESO.0070/CC RESO 1900 BROADWAY (CEQA) - EXHIBIT 1 - CEQA CONSISTENCY CHECK LIST REV: 10-23-24 VR Page 35 of 135
