DERP-FUDS Ft. Pierce Naval Amphibious Training Base

Defense Environmental Restoration Program (DERP)

Congressional District: 18



Appropriated by the Environmental Restoration-Formerly Used Defense Sites (ER-FUDS) account under the Military Munitions Response Program (MMRP). The Ft. Pierce Naval Amphibious Training Base (NATB) is a Formerly Used Defense Site (FUDS) totaling 35,650 land and water acres in Martin, St. Lucie and Indian River Counties, Florida, extending from near Jensen Beach north to approximately 5 miles south of Vero Beach, Florida on North and South Hutchinson Islands. The U.S. acquired the land in 1943. The installation was a training site during World War II for the invasion of Europe and included submerged obstacle training areas, mine removal training areas, beach landing sites, and anti-aircraft gunnery training areas. Personnel training at the base included the combat demolition research unit, underwater demolition teams, combat demolition units, attack battened landing craft units, rocket and anti-aircraft gunnery units, and construction battalions. The site was also used for amphibious assault training. Up to 40,000 personnel were trained at the installation. Most of the facilities were removed when the installation was closed in 1946, and the property was returned to the owners. Subsequently, much of the beach property has been extensively subdivided and heavily developed.



Estimated Total Cost $33,421,800
Estimated Total Cost to Complete (MMRP) $23,364,200
Allocation thru FY17 $9,577,600
Allocation for FY18 $480,000



The site was divided into one Building Demolition/Debris Removal (BD/DR) Project 00 and seven Munitions Response Sites (MRS) as follows: Chemical Warfare Agent Test Area (Project 01), Engineer Board Area (Project 02), Naval Demolition Research Area (Project 03), Naval Combat Demolition Unit Area (Project 04), Offshore Obstacle Area (Project 05), South Island Bombing Range (Project 06), Anti-Aircraft Gunnery Range (Project 07). A Remedial Investigation (RI) to determine the nature and extent of the munition hazard present was completed at the Chemical Warfare Agent (CWA) Test Area in FY13. No CWA hazard was identified and a No Further Action Decision Document was signed and approved. BD/DR Project 00 to remove remaining offshore obstacles was completed in FY16. During the execution of that effort two unexploded ordnance items, consisting of one 1000lb and one 500lb general purpose bombs were identified. This triggered a Time Critical Removal Action (TCRA) in the Offshore Obstacle Area. The TCRA was completed in FY16, with the identification and disposal of nine additional unexploded ordnance items. Site Inspections (SI) were completed at the Naval Combat Demolition Unit Area, South Island Bombing Range, and Anti-Aircraft Gunnery Range in FY15. No ordnance or contamination associated with the military’s use of the sites was identified, and no further action was recommended and approved for each of these projects. This, along with the previous no further action determination for the Chemical Warfare Agent Test Area, resulted in all the projects located on South Hutchinson Island being closed out, with no further investigation required there. A Remedial Investigation/Feasibility Study (RI/FS) is currently under way at the Engineer Board Area, Naval Demolition Research Area, and the Offshore Obstacle Area to determine the nature and extent of any remaining ordnance hazard, if present, from the military training conducted there. Field crews were forced to demobilize in the latter half of 2017 due to the impact of hurricane Irma. A limited remobilization effort was hindered by the early return of winter residents, swelling the local population, which would have seriously complicated resident evacuations during the intrusive phase of the RI/FS. Field crews again demobilized and plan to remobilize back to the project sites in late Spring/early summer of 2018 when the resident population is smaller and the impacts of the evacuations will be less burdensome.
