Redwood City Stormwater Roadmap <br />Appendix A: Data Review <br />September 2025 A-12 Schaaf & Wheeler <br />A.5.2 Existing Studies <br />Comprehensive analyses have been conducted to assess regional vulnerabilities to sea-level <br />rise and tidal impacts. <br />The Regional Shoreline Adaptation Plan (BCDC, 2024) provides guidelines for coordinated local <br />planning efforts, highlighting strategic regional priorities such as protecting critical infrastructure, <br />ecosystem resilience, community health, and collaborative governance approaches. <br />The San Francisco Bay Tidal Datums and Extreme Tides Study (AECOM, 2016) presented <br />detailed tidal data for over 900 locations, essential for floodplain management and adaptation <br />strategies. <br />The Sea-Level Rise Vulnerability and Adaptation Planning Study (ESA, 2024) for Redwood City <br />specifically identifies shoreline vulnerabilities, predicts future flooding scenarios due to rising <br />tides and groundwater emergence, and recommends phased adaptation strategies, including <br />levee and floodwall enhancements. <br />A.5.3 Design Guidance <br />The State of California Sea Level Rise Guidance (Ocean Protection Council, 2024) is publicly <br />available and provides updated sea level scenarios incorporating recent scientific <br />advancements, with projections indicating a statewide likely rise of 0.8 feet by 2050 and <br />between 1.6 to 3.1 feet by 2100, depending on emission trajectories. <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br />11.A. - Page 51 of 53 <br />482
