While DC is not a coastal city, it regulates development along the Anacostia River, Potomac River, and Rock Creek through floodplain management rules and the Anacostia Waterfront Development Zone under DC Code Section 2-1226.36. Waterfront projects face enhanced stormwater and environmental review requirements.
DC's waterfront development regulations focus on the Anacostia Waterfront Development Zone, which covers areas along the Anacostia River slated for redevelopment. Projects in this zone must meet enhanced stormwater retention standards under DC Code Section 2-1226.36, including treating and retaining stormwater from the 95th percentile storm event. The National Capital Planning Commission (NCPC) also reviews projects along the Potomac and in federal parkland. Shoreline stabilization, habitat restoration, and public access to waterways are prioritized in DC's Comprehensive Plan.
Non-compliant waterfront projects may face denial of building permits, required redesign, fines from DOEE, and potential federal enforcement for projects impacting navigable waters.
