<< Back to Clean Water Construction Grant Program main page

Stormwater Green Infrastructure Projects include techniques and plantings used to reduce stormwater runoff through groundwater infiltration, evapotranspiration, and rainwater harvesting; and projects designed to protect, restore, or construct stream and wetland ecosystems.

Project examplesBroad Branch Stream Daylighting Pre- and Post-construction

  • Green streets;
  • Permeable pavement;
  • Bioretention;
  • Green roofs;
  • Cisterns for harvesting and reuse of stormwater;
  • Street tree/urban forestry/tree box expansion;
  • Downspout disconnection;
  • Wetland restoration;
  • Stream restoration and daylighting;
  • Sustainable landscaping and site design;
  • Other practices that mimic natural hydrology to provide a water quality benefit; and
  • Equipment to maintain these practices, such as a vacuum-powered street sweeping of permeable pavers.

  • Project contributes to the achievement, maintenance, or compliance with the enforceable requirements of the CWA;
  • Project site is publicly owned and located in the District of Columbia;

  • Projects must be voluntary, and as such, cannot be used to meet the stormwater management requirements of 21 DCMR Chapter 5;
  • Application includes proof of permission from the property owner;
  • Project must include construction; however, funds can also be used for planning, survey, design, permitting, project-related outreach, and educational signage;
  • Application must present a project that can be completed within three-years; alternatively, the project can be broken into design and construction phases, with each being completed within a three-year time period;
  • Application must include a feasible plan for maintenance of the structure, restoration, or planting that ensures continuing functionality; and
  • Application must identify the planned source and amount of non-federal matching funds to be used for the project.
