SRCs Reduce Stormwater Runoff with Green Infrastructure

The Stormwater Retention Credit (SRC) Trading Program helps to leverage private investment in GI. SRCs, which are generated by GI or by removing impervious surfaces, can be sold on the market to development projects regulated under DOEE’s stormwater management regulations. Participants who install SRC-generating projects in areas that drain directly to District waterbodies without treatment also have the option to sell SRCs to DOEE at a fixed price through the SRC Price Lock Program. The SRC Price Lock Program provides the confidence necessary for investors to commit funding to GI projects in the areas that need GI most.

Stormwater runoff carries harmful pollutants like pet waste, oil, grease, sediment, and litter into the District of Columbia’s waterbodies through storm drains or directly via over-land flow. Green infrastructure (GI) practices like rain gardens, green roofs, and other similar practices capture and filter runoff, recharging groundwater or re-using water for irrigation or other non-potable uses. GI is essential for creating a Sustainable DC and making the District’s rivers fishable and swimmable. Agency Website.
