The South River Preserve, located in Waynesboro, Virginia, is currently listed as an EPA brownfield. The site received funding as part of the Natural Resource Damage Assessment and Restoration (NRDAR) program to remediate mercury contamination downstream of a decommissioned DuPont facility.

This presentation focuses on the stormwater engineering components involved in the master planning and Phase I design of the project, including Virginia Stormwater Management Program (VSMP) and floodplain compliance strategies. A brief background of the project’s conception and funding will be provided, followed by an exploration of the unique challenges and opportunities presented by the location of the site and the significance of a strong landscape architecture-engineering partnership through the duration of the project.
