Hamilton Field Restoration Project



State Coastal Conservancy, NOAA Office for Coastal Management, and San Francisco Bay and Outer Coast Sentinel Site Cooperative




This website provides access to information about the restoration work of tidal and seasonal wetlands on the former Hamilton Army Airfield and the adjacent North Antenna Field (NAF) and Bel Marin Keys Unit V (BMK) properties. The project is a collaboration between US Army Corps of Engineers and the California State Coastal Conservancy. In the first phase of the project approximately 6 million cubic yards of dredged sediment was placed on the airfield create tidal marsh. This entailed the largest beneficial reuse of dredged sediment that had ever occurred previously at a wetland restoration site. The next major phase of the project is to restore tidal and seasonal wetlands at the NAF and BMK properties, an area three times larger than the restored airfield. The website provides information about the restoration work, ways to visit the site as well as ways to get involved as a volunteer.
