The partnership includes the N.C. Department of Transportation and the Department of Environment & Natural Resources' Shellfish Sanitation and Recreational Water Quality Section and the N.C. Coastal Federation. It was formed to develop methods for enhancing the identification and distribution of information related to stormwater problem areas potentially affecting shellfish harvesting waters.
This innovative partnership is designed to improve the efficiency and effectiveness of various NCDOT NPDES permit compliance initiatives in the coastal zone, while also supporting the goals of NCDENR's Coastal Habitat Protection Plan.

NCDOT teamed up with the Town of Kure Beach, the Cape Fear Council of Governments, and NCDENR's Shellfish Sanitation and Recreational Water Quality Section and Wilmington Regional Office to evaluate the impact on public beaches of potential pathogens carried in stormwater runoff. Structural best management practices were installed to capture the first 0.5 inches from two sub basins. Positive partnering of the stakeholders to address a mutual concern resulted in this proactive project.

NCDOT has developed a preliminary Geographic Information System-based ESM to coordinate sensitive geographic information necessary to implement the post-construction controls permit requirements and other requirements under North Carolina regulations.

NCDOT has an environmental education component in the Post-Construction Controls Program. Some stormwater best management practices such as bioretention areas are being installed at selected rest areas in North Carolina. This provides the Highway Stormwater Program an opportunity for the public to take a closer look at some of the stormwater control devices utilized. The NCDOT rest area in Duplin County on Interstate 40 has both an inside and outside environmental display explaining stormwater and the use of bioretention areas.
