The Coastal Sediment Management Workgroup (CSMW) Web Map is designed to provide access to CSMW’s data holdings as collected from coastal regional sediment management plans, agency departments and other government agencies. This web map is provided by CSMW and the California Natural Resources Agency to allow users to easily make coastal sediment maps for planning, report generation and other tasks. This Portal webmap is hosted through the Mobile District of the U.S. Army Corps of Engineers.

When using the web map, zoom to your area of interest, or use the search box to locate an address, city, or other feature. Use the print button, to produce a report or to generate images for use in any custom reporting.
