Findings and Statements Required by the California Environmental Quality Act Redwood City Transit District DTPP Amendments 36 ESA / 202100421.00 Subsequent Environmental Impact Report October 2022 Mitigation Measure GEO-2 would reduce soil erosion and sedimentation impacts to a less than significant level because it would require applicants for future development projects in the Transit District area involving a grading area of 10,000 or more square feet to prepare erosion control plans subject to City approval and consistent with the project Stormwater Pollution Prevention Plans (SWPPPs) as well as BMPs specified by the Redwood City Stormwater Management and Discharge Control Program (Municipal Code 27A) to be implemented during construction. Impact GEO-4: Implementation of the proposed Transit District DTPP Amendments would not be located on expansive or corrosive soil creating substantial direct or indirect risks to life or property. Mitigation Measures. SEIR Mitigation Measures GEO-4a and GEO-4b (FSEIR, pp. 16- 11 to 16-12) will be implemented for the Project as provided in the MMRP. Findings Regarding Impact GEO-4: Based on the FSEIR and the entire record before the City, the Council finds that Mitigation Measures GEO-4a and GEO-4 would substantially lessen the severity of Impact GEO-4, such that this potential impact would be less than significant. Mitigation Measure GEO-4a would reduce expansive soil impacts to a less than significant level because it would 1) require analysis of expansive soil hazards and full remediation of expansive soils, or site specific recommendations to fully mitigate the effects of weak or expansive soils, as reviewed by a City-retained registered geologist, that are submitted with the building permit application, and 2) require deed restrictions to prohibit significant modification of finished lot grades that would adversely affect site drainage. Mitigation Measure GEO-4b would 1) require water systems and other buried metal infrastructure in all future development within the Transit District area to have protective coating conforming to the City’s water system design criteria and specifications; and 2) require concrete mix designs to conform to state Department of Transportation standards regarding corrosion. Impact GEO-6: Implementation of the proposed Transit District DTPP Amendments would not directly or indirectly destroy a unique paleontological resource or site or unique geologic feature. Mitigation Measures. SEIR Mitigation Measure GEO-6 (FSEIR, p. 16-13) will be implemented for the Project as provided in the MMRP. Findings Regarding Impact GEO-6: Based on the FSEIR and the entire record before the City, the Council finds that Mitigation Measure GEO-6 would substantially lessen the severity of Impact GEO-6, such that this potential impact would be less than significant. Mitigation Measure GEO-6 would require that prior to issuance of grading or demolition permits, the City, in coordination with a qualified paleontologist, shall assess individual development project proposals within the Transit District area for the potential to destroy or damage unique paleontological resources. Should the paleontologist determine that the proposal has the potential to damage paleontological resources, the paleontologist shall
