Stormwater

Watershed retrofit projects will treat 5 acres of impervious surface. These include:

  • Williamsburg Blvd (Old Dominion to 35th St N) = 1.07 acres
  • Williamsburg Blvd (Harrison to Edison N) = 1.67 acres
  • Kensington St. (at 33rd) = 0.77 acres
  • 32nd St N (at Kensington St.) = 0.42 acres

John Marshall Drive = 1.07 acres The project impervious surface will be approximately 0.68 acres DES Watershed Planner continue to look for opportunities Possible Constraints: for bio-retention and bio-swales:

  • Residents requests for additional street trees
  • Protection of existing trees
  • Narrow rights-of-way in many locations
  • Need to create a sidewalk that can support both pedestrian and bike traffic
  • Utility conflicts and slopes
