RECOMMENDATION
Recommendation
City staff recommends that the City Council adopt a resolution authorizing grant applications for South San Francisco Shoreline Protection and Connectivity Project feasibility study.
Body
BACKGROUND/DISCUSSION
The South San Francisco Protection and Connectivity Project aims to address the increasing risk of coastal flooding in the vulnerable area near the convergence of Lower Colma Creek and the San Francisco Bay. This area faces heightened flood risk due to storm-driven waves and rising sea levels. Predictions suggest that with a 24-inch rise in sea level and 5-year storm surge, various critical infrastructure including residences, businesses, Highway 101, and the South San Francisco/San Bruno Water Quality Control Plant (SSF-SB WQCP) could be affected (based on ART Bay Shoreline Flood Explorer). Notably, this area is predominantly inhabited by people of color who have historically faced disadvantages in access to services (Lower Colma Creek Continuing Authorities Program Section 103 Project, USACE, June 2022).
If flooding occurs as projected, there could be severe consequences, including risks to human life, property damage, and disruptions to essential services. The flooding of the SSF-SB WQCP, for instance, could lead to sewage backups, potentially contaminating homes, streets, and the Bay, with significant impacts on the community, infrastructure, and environment.
To tackle these challenges, South San Francisco plans to conduct a feasibility study exploring potential solutions to mitigate coastal flooding exacerbated by sea level rise and storm surges. This study will involve collaboration with various agencies, such as the California Department of Transportation (Caltrans), San Mateo County Transit District (SamTrans), OneShoreline, City of San Bruno, Caltrain, San Francisco International Airport (SFO), and appropriate regulatory agencies such as BCDC. The goal of this study is to assess alternatives for coastal flood protection that could safeguard residences, businesses, transportation infrastructure, and other critical facilities like SFO and the SSF-SB WQCP. Community engagement and input from environmental stakeholders will be integral throughout the process.
The feasibility study will employ specific criteria to evaluate proposed solutions. This includes technical feasibility, drawing upon the best available climate science, financial viability, community acceptance, and considering environmental impact, with a focus on minimizing bay fill and incorporating nature-based approaches. The study will also consider connectivity possibilities, such as connecting Interstate 380 to the Oyster Point area to provide an additional elevated sea level rise-resistant emergency route and support access to a fast-growing life science and logistics hub. Through a community-driven design process, potential solutions will be refined and analyzed, ensuring alignment with community needs and values. This inclusive approach will guide the selection of a preferred alternative. Finally, the findings, encompassing conceptual design documents and cost estimates, will be compiled into a comprehensive report.
FISCAL IMPACT
There is no fiscal impact to the Fiscal Year (FY) 2023-24 Budget. Staff continuously scan for various grant funding opportunities. Upon successful award of grant(s), staff will work with Council as necessary for budget appropriation to ensure sufficient funds to cover a local match.
RELATIONSHIP TO STRATEGIC PLAN
Approval of this action will contribute to the City’s Strategic Plan outcome of improved Quality of Life by maintaining and improving infrastructure to serve the public.
CONCLUSION
City staff recommends that the City Council adopt a resolution authorizing grant applications for South San Francisco Shoreline Protection and Connectivity Project feasibility.
