RiverSmart Permeable Surface Rebate Program

The Alliance for the Chesapeake Bay, in partnership with the District of Columbia Department of Energy & Environment (DOEE), is offering rebates to qualifying District homeowners, business owners, and houses of worship who remove impervious surfaces and replace the areas with vegetation or permeable pavers. An impervious surface is a ground area where water cannot soak through, such as paved driveways, patios, and parking lots. Permeable pavers are materials constructed and used with the purpose of allowing water to soak into the ground while still being used as driveways, patios, parking lots, etc.

RiverSmart Permeable Paver Program

The Permeable Surface Rebate Program is temporarily closed through October 1, 2020 while rebate incentives are under revision. Please contact Laura Todd at with questions. 

The Permeable Surface Rebate Program offers rebates based on the square footage of impervious surface removed and replaced with permeable surface.

Replacement of impervious surface with vegetation:

Replacement of impervious surface with permeable pavers: 

$5.00 per s.f. of project area minimum project area is 200 s.f.

$10.00 per s.f. of project area minimum project area is 100 s.f.

Depending on your location in the District there can be a rebate maximum. For properties in the Combined Sewage Overflow (CSO) portion of the District there is a rebate maximum of $3,000, however properties located in the Municipal Separate Storm Sewer System (MS4) area do not have a rebate maximum.

Why Replace Impervious Surfaces?

Water cannot pass through impervious surfaces and soak into the soil below. When it rains, water flows over these hard surfaces collecting soil, litter, salt, pesticides, oil, fertilizers, and other pollutants, creating stormwater. This stormwater drains into manmade drainage systems consisting of inlets and underground pipes commonly referred to as “storm sewers”. The majority of stormwater entering storm sewers does not receive any treatment before it enters the Potomac and Anacostia Rivers and Rock Creek, and ultimately, the Chesapeake Bay.

Benefits of Permeable Pavers and Revegetation

Permeable Pavers and Revegetation have many benefits including:

  • Improving drainage in areas prone to flooding
  • Beautifying outdoor spaces
  • Decreasing stormwater runoff and erosion
  • Helping our local waterways, and thus the Chesapeake Bay
  • Enhancing stormwater runoff awareness
