The buildings, which had previously been fabricated and assembled by the San Juan contractor, included barracks for 200 men, quarters for 25 officers, a 10-bed dispensary, a power plant, ten 5000-gallon steel tanks for gasoline storage, three magazines, a cold-storage plant, and two industrial buildings. Concrete floors, prefabricated lightweight steel frames, and stucco exteriors were used for all buildings.
Rainfall collected on a 60,000-square-foot concrete catchment area furnished the fresh-water supply for the station. It was stored in two 80,000-gallon steel tanks and chlorinated before use.
The waterfront layout, as prepared by the Bureau, centered about a 40-foot timber seaplane ramp, a concrete parking apron, 300 by 800 feet, and a 40-by-350-foot tender pier with a timber deck supported on steel piles. A 500,000-cubic-yard dredging operation was necessary to deepen the water of the bay for the seaplane runways and the approach channel to the tender pier.
With exception of a few minor additions and improvements made at various times during 1942, the station was completed in December 1941. No Seabee personnel participated in its development other than to make a few minor repairs and alterations during the early summer of 1943. These men were drawn temporarily from battalions stationed at Trinidad.
The air station on St. Lucia was decommissioned on September 1, 1943, and placed in a caretaker
