Turpentine Run, VI
Investigations (I)
Congressional District: U.S. Virgin Islands


The Turpentine Run area is located about two miles southeast of the city of Charlotte Amalie, on the southeastern end of the island of St. Thomas, U.S. Virgin Islands. Adjacent to the Nadir residential area there is an existing concrete channel, which carries Turpentine Run past the developed area. The capacity of this channel is insufficient to carry flood flows thereby causing flooding in the development. In addition to monetary damage, the nature of the flooding creates a substantial and significant threat to the safety of area residents. The recommended plan involves replacement of the existing concrete channel with a new channel having greater capacity. Improvements would begin at the north end of the Nadir development and end at a discharge point at Mangrove Lagoon. A levee would be constructed along the northern edge of the development. A sheetpile wall would run along the development side of the channel between the levee and a 40-foot long drop structure. From the drop structure, the channel is concrete and U-shaped for a distance of approximately 460 feet. It then transitions to a trapezoidal, earthen channel lined with riprap. Where possible, the existing concrete channel wall along the Nadir development will be left intact. The local sponsor replaced the existing Bovoni Road Bridge. Downstream from the new Bovoni Road Bridge to the Nadir racetrack, steel sheetpile is proposed for the west side of the channel. From just downstream of the replacement bridge, underground piping will run beneath the racetrack to Mangrove Lagoon.
