Flood Adaptation Strategy for State Route 4 through the San Joaquin Delta River

The San Joaquin Council of Governments (SJCOG), in partnership with Caltrans District 10, proposes a study to develop a Flood Adaptation Strategy (FAS) for State Route 4 (SR-4) through the San Joaquin Delta River. SR-4 is at high flood risk as it (1) runs through FEMA’s 100-year floodplain (2) serves as a goods movement connector and commuter route (3) and acts as an evacuation route for San Joaquin River Delta residents. The proposed FAS will assess flood impact, including the impact a flood event on the San Joaquin River Delta will have on evacuation routing, and generate a list of priority flood-resilient capital improvement projects that SJCOG, in partnership with Caltrans District 10, could program on SR-4.The FAS was identified as a Priority Adaptation Strategy in the agency’s 2022 Regional Resiliency Implementation Plan and Adaptation Guidance and aligns with state and federal climate and transportation priorities. The purpose of the proposed FAS, therefore, is to build on the 2022 Regional Resiliency Implementation Plan and Adaptation Guidance and develop a data-driven investment strategy for SR-4 as it experiences increasing flood risk. The proposed strategy will improve and enhance the resiliency of our regional transportation network to a flood event by ensuring the network can more easily absorb, recover from, and adapt to a flooding event. In addition to promoting climate and infrastructure resilience, the proposed strategy will also address public safety, economic resilience, and cost-savings, in the region with a focus that will provide public benefits by (1) minimizing injuries and fatalities as the SR-4 will be able to better support evacuation and emergency response (2) ensuring the continuous flow of people, goods, and services on the regional transportation network during a flood event (3) and reducing maintenance and repair costs on this transportation asset.Proposals should include information demonstrating the consultant’s understanding of the project, expertise and past performance conducting similar projects and project team as outlined in this solicitation. The top-ranking consulting firm, after evaluations are conducted by the evaluation panel, will enter contract negotiations with SJCOG.The Project cost estimate to complete the work as outlined in the RFP is $325,000. SJCOG anticipates the Project work will be completed within 12 months of receiving a notice to proceed.
