With the successful closure of the former Hamilton Army Airfield (HAAF), most of the land has been converted to civilian uses, including residential, commercial, park and open space, and schools. Ongoing activities at Hamilton include the Hamilton Wetland Restoration Project and some environmental cleanup and monitoring projects. 

Hamilton - Wetland Restoration Project

The wetland restoration project is envisioned to develop nearly 2500 acres of restored wetlands over three phases. The U.S. Army Corps of Engineers is the lead agency and the California State Coastal Conservancy is the local sponsor.

Hamilton – North Antenna Field

Beginning in October 2010 an increasing number of haul trucks have used the alternate route in back of the Hamilton Landfill, to enter and exit the North Antenna Field site. During operations, approximately 45 trucks a day in small convoys are using the road.

The truck drivers have stated that they are encountering a number of people using the haul road recreationally. This section is a narrow one lane road and parts are elevated. The road is posted with no trespassing signs and warnings of truck traffic and further steps are being taken to discourage recreational usage.

People in the area must refrain from using the road during working hours.

Haul Truck Status
2000 haul trucks have been used as of December 15, 2010
100 additional trucks will be needed for this phase

Navy Gas Station Groundwater Monitoring

The Department of the Navy (San Diego Navy BRAC PMO) continues to monitor the residual groundwater plume that resulted from fuel that leaked from underground storage tanks (USTs) at former gas station sites.  Monitoring has continued following an initial period of active treatment.  Recently, the Navy decided to perform a limited active treatment of the leading edge of the groundwater plume which has migrated near Landfill 26.  In November 2010, temporary power poles were installed to the site to provide electric power for the treatment facility.  It is anticipated that the temporary poles will be removed at the end of a two-year period. For more information, visit bracpmo.navy.mil.
