Coastal Climate Change Adaptation

The California Department of Water Resources (DWR) collaborated with the California Ocean Science Trust (OST) and the Scripps Institution of Oceanography (SIO) to equip local communities with tools and information to adapt to coastal flood hazards caused by climate change. A grant from the National Oceanic and Atmospheric Administration’s Coastal and Ocean Climate Applications program provided funding for the project, which was also supplemented with additional funds from DWR.

A two-year pilot study was conducted to introduce alternate approaches to local coastal floodplain management in California. This work supports non-regulatory approaches in complying with the Federal Emergency Management Agency’s (FEMA) National Flood Insurance Program (NFIP) in areas that could flood by utilizing regional-scale, sea-level-rise information from the National Research Council’s study, Sea-Level Rise for the Coasts of California, Oregon, and Washington: Past, Present, and Future, as well as information on waves and tides. SIO's recently-produced future water levels, which incorporate the NRC's sea-level rise projections, were translated into products useful for coastal planners and floodplain managers.
