Fort Pierce Naval Amphibious Training Base

Picayune Strand Pump StationThe Fort Pierce Naval Amphibious Training Base was a 19,280.48-acre site that extended approximately 25 miles from near Vero Beach to near Jensen Beach and included North and South Hutchinson Islands.The military acquired the site during World War II for the Navy to create a training facility. The Navy constructed more than 450 buildings and other improvements, such as roads and water and sewer systems. By January 1943, detachments of Scouts and Raiders began arriving.
 The base fulfilled two primary missions during World War II. Its original mission was amphibious training, including training for Naval Underwater Demolition Teams. Amphibious training missions included use of high explosive rockets, bombs, antiaircraft guns and small arms. During 1943, the Joint Army-Navy Experimental and Testing Board was established to develop and test procedures for breaching and removing beach fortifications expected to be encountered in Europe and Japan. Beaches were fortified along the northern portion of the base, and a variety of ordnance was tested against these fortifications. By 1946, the site was no longer needed, and the land was returned to the original owners. Much of the area comprising the former base has been developed and includes residential, commercial, governmental and educational facilities.

Over the years, the Corps has conducted a number of investigations to evaluate if any military-related materials remain at the site. We completed a Site Inspection in 2015 and concluded that a Remedial Investigation/Feasibility Study is necessary for three project areas: Project 02 Engineer Board Area, Project 03 Naval Demolition Research Area, and Project 05 Offshore Obstacle Area.Project 02 is on North Hutchinson Island in Indian River County and comprises approximately 473 acres. Munitions have been located in this area following the War, most recently being a Tiny Tim found in January 2017 during construction on a previously undeveloped parcel. Project 03 is 1,712 acres on North Hutchinson Island in both Indian River and St. Lucie Counties. Munitions have been found in this area as well, with the most recent ones found during a beach barrier removal project in 1998. The Offshore Obstacle Area (Project 05) is 3,895 acres in the Atlantic Ocean, east of North Hutchinson Island in Indian River and St. Lucie Counties. The Corps identified and removed munitions in this area during investigations conducted in 2014 and 2015.

The Corps is conducting a Remedial Investigation/Feasibility Study on portions of the former Fort Pierce Naval Amphibious Training Base to determine if anything remains in the area from the military’s training, and if so, in what amounts and locations.
