Pursuant to the National Environmental Policy Act of 1969 (NEPA), U.S.C. 4332(2)(C), the National Park Service (NPS) and Alexandria Renew Enterprises (AlexRenew) are preparing an Environmental Assessment (EA) to consider potential environmental effects of RiverRenew, a major infrastructure initiative to remediate the City of Alexandria's combined sewer system. RiverRenew (Proposed Action) falls within, and adjacent to the Potomac River waterfront including Jones Point Park, the Alexandria Seaport Foundation property, and the George Washington Memorial Parkway.

The purpose of the proposed actions is to reduce combined sewer overflows (CSO) into the Potomac River, Hooffs Run, and Hunting Creek from Alexandria's four existing combined sewer outfalls (CSOs 001- 004) during rain events. The Proposed Action is necessary to comply with a mandate from the Commonwealth of Virginia's State Legislature to reduce CSOs by July 1, 2025. AlexRenew and the City of Alexandria have established a partnership to comply with this milestone and have jointly authored a Long Term Control Plan Update (LTCPU) that establishes an approach to reduce Alexandria's CSOs. The LTCPU was developed to comply with legislative requirements established by the Virginia General Assembly, Virginia Department of Environmental Quality's Bacteria Total Maximum Daily Load for Hunting Creek, and the U.S. Environmental Protection Agency's CSO Policy.
