In September 2011, through the Conservation Technical Assistance Program (CTAP), NRCS awarded a grant to the St. Croix Environmental Association (SEA) to complete engineering designs and plans for two priority restoration projects identified in the St. Croix East End Marine Park (STXEEMP) watershed management plan.

The Hope and Carton Road network is one of the two project sites. The steep, eroding roads in this neighborhood have no formal drainage infrastructure. They are a major source of sediment to Solitude Bay, and a safety hazard for residents. Through the CTAP grant, SEA hired Horsley Witten Group, Inc. (HW) to develop a Master Drainage Plan for this road network and to design and install a demonstration rain garden in the neighborhood.

On October 25 & 26, 2012, SEA, HW and NRCS staff worked with Bates Trucking to excavate and shape the rain garden, and St. Croix LEAP donated and delivered mulch and compost.  On Saturday, October 27, 2012, homeowners Deb & Ed Cullen, partners and volunteers planted over 50 native or naturalized species purchased from the VI Waste Management Authority Greenhouse or donated by partners and residents. The rain garden got its first test a few weeks later, trapping over 2 inches of rainfall (right).

The rain garden pilot project installed in the Hope & Carton Hill neighborhood shows residents how to capture storm water runoff from their driveways and retain it on their properties. 20% of the total Hope & Carton Hill road network is driveways. Removing driveway runoff from the neighborhood road network will help to reduce road deterioration, improve road drainage and provide homeowners with a beautiful landscape. It will also reduce the amount of eroded sediment that reaches coastal waters, protecting coral reefs.
