NCDOT Highway Stormwater Program

About This Project

Managing stormwater isn’t just a concern in populated areas—anywhere that has large, impervious surfaces is a candidate for stormwater management. NCDOT’s Highway Stormwater Program, which is administered through an on-call contract, focuses on designing and implementing retrofits to stormwater Best Management Practices (BMPs) along specific state highways. Projects vary in size and scope, but all efforts are directed toward reducing water quantity and improving water quality.

Originally awarded an indefinite delivery contract in 2008, WithersRavenel is now in a sixth renewal of the on-call contract. Most of the projects are found along major waterways, including the Catawba River, South Deep Creek, Beaverdam Creek, and Dan River. For each projects, WithersRavenel provides a preliminary engineering memorandum with supporting calculations for approval, followed by construction drawings with associated NCDOT bid documentation and technical specifications. All design techniques conform to low impact design (LID) practices in order to meet state goals. WithersRavenel also leads bid administration and close coordination with NCDOT and state permitting agencies for each project.
