  • 1. Jenny Guillaume Environmental Protection Specialist RiverSmart Homes Watershed Protection Division RiverSmart Homes   Clean Water Starts in Your Yard  
  • 2. 17% of the urban and suburban areas in Chesapeake Bay watershed are impervious .
  • 3. Imperviousness
    • User fees for CSO and MS4 to be based on concept of “imperviousness”
      • i.e. hard surfaces that prevent drainage and infiltration of rainwater, and that increase stormwater runoff
      • Impervious cover is a good surrogate measure for stormwater runoff generated from a property
      • Examples: Parking lots, sidewalks, rooftops, etc.
  • 4. Impervious Area in the District of Columbia
    • Map of impervious area in Washington DC
    Map of impervious area in Chesapeake Bay watershed
  • 5. The Effects of Stormwater Runoff in the District of Columbia:
    • Over 34 miles of District rivers and streams do not support swimming or aquatic life use.
    • The major cause of impairment to District surface water is pathogens.
    • Combined sewer overflow and urban runoff are the main causes of pollution in District bodies of water.
  • 6. Stormwater Background
    • 1/3 of District served by combined sewer
    • 2/3 of District served by separate storm and sanitary sewers (MS4)
    CSO MS4 MS4 MS4 1 pipe 2 pipes
  • 7. Challenges with Managing Stormwater in DC
    • The Federal Government controls 1/3 of the District’s lands
      • Smaller tax base
      • Difficult to perform work on these lands
    • Combined Sewer System controlled by a non-District Government entity
    • State & Local Government at the same time
  • 8. Why Focus on Private Property?
    • Federal lands – where most space is available but they are not often a willing partner
    • Residential development makes up greatest land use in the District
    • Area the slowest for redevelopment & least likely to require stormwater retrofits
  • 9. Background: Tried in the past and failed.
    • Transportation difficulties –
      • 35% of District households do not own cars
      • Those with cars typically have small cars
    • Homeowners have difficulties installing and/or maintaining BMPs
      • Downspouts not or poorly disconnected
      • Dead trees
      • Rain barrels overflowing
    • City regulations
      • Inspections of disconnections
      • Installation of rain gardens and permeable pavement
  • 10. RiverSmart Homes Defined:

    • Homeowners receive up to $1,200 in landscaping services for one or more of the following landscape enhancements: Shade Trees, Rain Barrels, Pervious Pavers, Rain Gardens and BayScaping.
