Turpentine Run CAP Conversion project

The purpose of the project is to reduce flood damage to the Nadir development along Turpentine Run.  The Corps originally assessed the effects of the proposed action in the November 1994 Turpentine Run/Nadir Area, St. Thomas, U.S. Virgin Islands (USVI) Detailed Project Report (DPR) and Environmental Assessment (EA).  The proposed 1994 Recommended Plan consists of the following:
  • 460-foot long concrete “U” shape channel that transitions to a trapezoidal, earthen channel (1,385 feet long) lined with rip rap; 

  • Drop structure and 170-foot long sheetpile wall along the developed side of the channel;

  • 260-foot levee along the northern edge of Nadir;

  • 1,300-foot long levee starting south of the new Bovoni Road Bridge and ending at the Nadir racetrack with rip rap on the left side of the channel as it flows around the corner of the racetrack;

  • Interior drainage conveyance from the existing small concrete channel by a 72-inch underground pipe (length of 1,745 feet) which run under the levee footprint and racetrack and ultimately discharge into Mangrove Lagoon.

     

A review of the project is currently being conducted and provides updates to the 1994 analysis.
