Findings and Statements Required by the California Environmental Quality Act Redwood City DTPP Plan-Wide Amendments 35 ESA / 202100421.01 Subsequent Environmental Impact Report May 2023 Findings Regarding Impact NO-3: Based on the FSEIR and the entire record before the City, the Council finds that Mitigation Measure NO-3 would substantially lessen the severity of Impact NO-3, such that this potential impact would be less than significant . Mitigation Measure NO-3 would impose conditions of approval that require the applicant for each subsequent development project to ensure that ground-borne vibration abatement measures are implemented by the construction contractor to reduce ground-borne vibration levels generated by future site-specific demolition and construction activities. Those conditions will: restrict the hours in which vibration-generating activity is permitted; require written notice of projected construction schedules be provided to affected occupants; require pre-construction site survey s to document the condition of any historic structure located within 200 feet of pile driving activities; and require monitoring of pile driving vibration levels to within appropriate thresholds. 12. Air Quality Impact AQ-2: Implementation of the DTPP Plan-Wide Amendments would result in a cumulatively considerable net increase of criteria pollutants for which the project region is non-attainment under an applicable federal or state ambient air quality standard. Mitigation Measures. SEIR Mitigation Measures AQ-2a and AQ-2b (SEIR, pp. 12-37 to 12-39) will be implemented for the Project as provided in the MMRP. Findings Regarding Impact AQ-2: Based on the FSEIR and the entire record before the City, the Council finds that Mitigation Measures AQ-2a and AQ-2b would substantially lessen the severity of Impact AQ-2. Mitigation Measure AQ-2a requires implementation of best management practices consistent with Bay Area Air Quality Management District (BAAQMD) recommendations fugitive dust emissions. Mitigation Measure AQ-2b requires that for projects that exceed BAAQMD screening levels, a project-level criteria air pollutant assessment of construction and operational emissions shall be prepared at the time the project is proposed; and if the analysis finds that the project could result in criteria air pollutant emissions that exceed BAAQMD significance thresholds, the project applicant emission reduction measures shall be implemented to the degree necessary to reduce the impact to less than the significance thresholds. This includes the use of clean construction equipment (e.g., electric construction equipment, diesel engines with Tier 4 Final of-road emissions standards; limiting idling time); operational emission reductions (e.g., provision of all electric gas infrastructure and EV charging infrastructure); a nd payment of emission offset fees. However, since the specific emissions associated with future projects are not currently known, the effectiveness of emission reduction measures cannot be definitively determined; and implementation of any emissions reduction project(s) that would be undertaken by BAAQMD are outside the jurisdiction and control of the City and not fully within the control of the project applicants. Consequently, air pollutants from construction and operation of subsequent projects developed under the proposed DTPP Plan-Wide Amendments could result in a new and more severe impact than the impact identified in the DTPP FEIR, and impact would conservatively be significant and unavoidable.
