Homestead Gardens

Homestead Gardens

Davidsonville, MD

The project was funded by the Chesapeake Bay Trust, the Maryland Department of Natural Resources, and Homestead Gardens and designed and constructed by Underwood & Associates.

In addition to restoring headwater wetland functions and habitat, the 1-acre project treats 12 acres of runoff coming from parking lots, building roofs, and nursery operations flowing directly to a tributary of Beard’s Creek within the South River watershed – all of which was previously untreated and flowing through manmade ditches in mowed lawn.

This project slows the movement of storm flows through the site by allowing a series of terraced wetland pools to trap sediment and process nutrients before water leaves the property: Smaller rain events infiltrate into the existing soils, while higher flows from major storms are able to pass safely downslope.  Pollution loving wetland plants, including switchgrass, Atlantic white cedar, and Sweetbay Magnolia, were installed to bolster the new wetland habitat and also increase its ability to process polluted runoff.
