Large development projects in the District of Columbia must manage stormwater runoff post-construction by installing on-site and off-site Best Management Practices (BMP) such as green roofs, rain gardens, cisterns, and permeable pavement. There is also flexibility to comply with part, or sometimes all, of the stormwater requirements off-site by using Stormwater Retention Credits (SRCs). For full details about compliance requirements, refer to:
- The District’s Stormwater Management Regulations, published in Chapter 5 of Title 21 of the District of Columbia Municipal Regulations
- The District’s Stormwater Management Guidebook (SWMG), which includes design requirements, the plan review process, and other technical guidance
