Detention Pond Retrofit Success: Mulberry Run Wetlands

Waynesboro's Jefferson Park Neighborhood underwent a remarkable transformation in 2016. What once was a boggy, grassy field has become a 10-acre manmade wetland that's both a haven for wildlife and the community. For nearly 20 years, the site was a dry detention pond that during heavy rain provided for the short-term detention of stormwater runoff from the developed area around the pond and allowed for a controlled release from the structure to a nearby stream. This detention pond did help with the flooding issues in the surrounding neighborhood, but polluted runoff still needed to be addressed.

So, the City undertook the project three years ago to reduce the amount of polluted runoff going into Mulberry Run, and consequently the South River and the Chesapeake Bay. By creating the man-made Mulberry Run Wetlands, named after the creek that is downstream of the site, the new wetlands not only provides for controlling stormwater runoff as before, but food and shelter for a host of wildlife. Naturalists have reported spotting green herons, Carolina wrens, red-wing blackbirds, numerous species of butterflies, and many more. The size of the wetlands is approximately 10 acres with an estimated 300 pounds of phosphorus being removed annually.

The wetlands were paid for completely by state grants and loans, including the Stormwater Local Assistance Fund (SLAF) for $860,000.00 and the Virginia Clean Water Revolving Loan Fund for $860,000.00. Total project cost was $1.6 million to construct. Since its completion in 2016, the project has been recognized by the EPA as an innovative environmental success and received a habitat creation award from the Chesapeake Stormwater Network.
