Construction began on the first part of the Stream and Wetland Assessment Management Park's Phase 5 in April 2012 and was completed by September of that year.

The Phase 5 BMP (Best Management Practices) site is a 0.4-acre extended detention stormwater wetland. It lies along Duke University Road just North of the intersection with NC Highway 751. The stormwater BMP's catchment area is about two-thirds impervious with buildings and parking lots. By retaining stormwater runoff for an extended period rather than letting the water flow quickly down the eroded stream channel through the watershed, the BMP promotes the retention and settling of pollutants and sediment before the water travels downstream to Jordan Lake, a major drinking water source for the area.


Construction on the second part of Phase V, restoration of 734 linear feet of an unnamed Upper Sandy Creek tributary adjacent to the BMP, was completed in 2014. The eroded stream channel had high flows and sediment loads, and it was deeply cut with steep banks. The new meandering stream channel will slow water flow and reconnect the stream to the adjacent wetland.


The project is the result of collaboration between Duke University and the Durham County Soil and Water Conservation District. Funding was provided by the North Carolina Clean Water Management Trust Fund (CWMTF), a program established by the state legislature to issue grants to local governments, state agencies and conservation non-profits to help finance projects that specifically address water pollution problems.

The campus news outlet DukeTODAY published an online article about Phase 5 shortly after work began on the project early in 2012 .
