South Haven Bioswale​

  • Location: Anne Arundel County, MD
  • Completion Date: July 2016

This stormwater retrofit project incorporated the installation of two bioswale areas and one outfall stabilization in Annapolis. The intent of this project was to treat stormwater runoff from approximately 5.17 acres, which included treatment of 0.77 acres of impervious area from nearby roads and homes. The outfall stabilization was specifically implemented to reduce streamside erosion along the South River.

The restoration plans, designed by the Center for Watershed Protection, included the enhancement of two bioswales. The existing were ineffectively filtering surface water runoff being transported to the South River. Implementation consisted of excavating the existing swales to plan specific depths, lining each with stone and PVC pipe to promote effective filtration and drainage. Each trench was then filled with biomedia, and then vegetated with turf grass for stabilization.  

Additionally, Ecotone facilitated outfall improvement measures to Broad Creek. This included the installation of a plunge poll lined with rock, and consistent grading to maintain a steady slope to Broad Creek. River rock was placed along the thalweg and J-hook structures were installed to increased stabilization. 

Funding for this project, was secured through the Center for Watershed Protection, Inc., under Maryland Department of Natural Resources Chesapeake and Atlantic Coastal Bays Trust Fund.
