The District Department of the Environment (DDOE) finalized a new regulatory framework for stormwater management by large development sites in the District of Columbia.  The new regulations were published in the DC Register on Friday, July 19, 2013.

The new framework includes stormwater retention performance standards that will dramatically reduce stormwater runoff’s harmful impacts to the Anacostia and Potomac Rivers, Rock Creek, and their tributaries.  It also includes an innovative Stormwater Retention Credit (SRC) trading program, which is the first of its kind in the nation and has the potential to increase the new standards’ benefit to District waterbodies while reducing the cost of compliance and providing other sustainability benefits. A fact sheet explaining the final rule along with presentations and the final version of the compliance spreadsheet that take you step by step through the new regulations can be accessed below.

Check out our newly released DC-specific Urban BMP fact sheets. These ‘fact sheets’ explain how to use each of the CBP-approved Urban BMPs in the District. Enjoy!
