1) Determination of Design Level Protection. Review past analysis to determine if the hydrologic and hydraulic conditions require updates to be consistent with current and best practice for designing storm facilities in the face of climate change (ex. design storm, groundwater, seal level rise, etc.). Recommend if a previously modeled scenario can be used to design system upgrades or if revised modeling conditions are needed. If updated modeling is needed, recommend modeling parameters and software. 2) Updated Modeling Central/Eastshore and Golf Course Pump Stations and Tributary Area. Model the Central/Eastshore and Golf Course pump stations and tributary areas with recommended software and climate change parameters to identify system capacity issues. The previously prepared Mike Urban 2013 model will be provided to the successful proposer. This may include pump station upgrades, installation of storm pipes where they currently do not exist, upsizing existing pipe and outfall and any other improvements to convey the storm flow without surface flooding. For the Golf Course, alternatives to conveying storm flow through the Golf Course should be analyzed given the operational challenges with the earthen sloughs and shallow groundwater. Recommend capital improvements for each watershed and a prioritized implementation plan. 3) Grant Funding. Advise on state and federal funding opportunities and how to package the recommended improvements to be best positioned to pursue funding. Funding considerations may include, but not be limited to, Federal Emergency Management Agency’s (FEMA) Building Resilient Infrastructure and Communities, Hazard Mitigation and Flood Mitigation Assistance grant programs, Pre-Disaster Mitigation Program and Safeguarding Tomorrow Revolving Loan Fund Programs. It may also include California’s Infrastructure State Revolving Fund Program and future other opportunities in any successful climate bond. 4) Conceptual Designs. Advance designs for the improvements, as needed by the grant application. This likely will be at least schematic level design and include a FEMA Benefit-Cost Analysis to determine future risk reduction benefits of the improvements and compare those benefits to their costs.
