San Francisco Littoral Cell Coastal Regional Sediment Management Plan

San Francisco Littoral Cell Coastal Regional Sediment Management Plan

The Coastal Sediment Management Workgroup (CSMW), a taskforce co-chaired by the U.S. Army Corps of Engineers and the California Natural Resources Agency, is focused on the adverse impacts of coastal erosion on coastal habitats. The CSMW is working with other federal, state, and local/regional entities to implement regional sediment management that will augment or restore natural processes along the Pacific coastline in San Francisco and San Mateo Counties.

ESA developed the Coastal Regional Sediment Management Plan (CRSMP), a guidance and policy document for a segment of the San Francisco Littoral Cell along the Bay Area coastline. The CRSMP details how regional sediment management can be applied in a rapid, cost-effective, and resource-protective manner. Preparing a CRSMP entails specifying how governance, outreach, and technical approaches can support beneficial use of sediment resources without causing environmental degradation or public nuisance. Because the study region is heavily urbanized and includes the entrance to San Francisco Bay, many components were required to produce a valuable document. Our team assessed geological and geomorphic processes, habitats, and terrestrial and marine species of concern; identified infrastructure at risk; analyzed the economic costs/benefits; evaluated public access; and reviewed policies that may influence sediment management along 17 miles of coastline. To ensure the CRSMP recommendations are useful for long-term planning, our team considered the impacts and risk of climate change and sea level rise. Community ownership is critical to the success of the CRSMP and was encouraged through public meetings and a technical working group.

The CRSMP will be widely used by local and regional decision-makers to develop policies and execute management plans for the future vitality of beaches and shoreline areas along the coastal region from the Golden Gate to Pedro Point in Pacifica.
