Landsburgh Park Floodable Play Lawn Visualization (DOEE and Ramboll/Moody Graham) Southwest and Buzzard Point Flood Resilience Strategy
COG is working with the District of Columbia and Prince George’s County, with support from consulting firms ICF, Straughan Environmental, and CHplanning, on a project to address flood concerns across jurisdictional boundaries. The Regional Blue-Green Infrastructure Community Engagement and Planning Project looks to increase resilience in three subwatersheds that span the District of Columbia and Prince George’s County—Watts Branch and Arundel Canal (part of the Northwest Branch) of the Anacostia River and Oxon Run which is part of the Potomac River watershed.
This collaborative project will prioritize areas vulnerable to flooding and other social, economic, and environmental stresses. The project focuses on engaging traditionally disadvantaged communities in flood prone areas to identify BGI projects that can assist in the mitigation of flood impacts. Through community-driven efforts, the project seeks to develop a regional framework to reduce flood risk, provide stormwater capabilities, and increase recreational green space, that can be replicated throughout metropolitan Washington. The project is funded through FEMA's Regional Catastrophic Preparedness Grant Program.

PROJECT BACKGROUND AND GOALS
The project focuses on the two shared subwatersheds of the Anacostia River and one subwatershed of the Potomac River: The two project areas of the Anacostia River are Arundel Canal, a tributary of the Northwest Branch which originates in the District of Columbia and Watts Branch which originates in Prince George’s County. For the Potomac River, the project focus will be the Oxon Run subwatershed. All three project areas share the commonality of flowing between the jurisdictional boundaries of the District and Prince George’s County.
The planning study will identify potential BGI projects intended to reduce flood risk, improve water quality, reduce stormwater volume, add to recreational spaces, and promote environmental sustainability. Blue-green infrastructure refers to the combination of 'blue' water-related functions with 'green' nature-based solutions such as vegetation and parks. The BGI project will address critical urban challenges including flooding and climate change by leveraging natural solutions, enhancing urban biodiversity, improving air quality, and creating recreational spaces that make cities healthier and more resilient. The planning study will also create partnerships for implementation of proposed projects in collaboration with the District and Prince George’s County.
The project aims to advance the following goals:
- Enhance Flood Resilience through Regional Collaboration: Build upon current flood mitigation efforts in the three watersheds to maximize impact and ensure cohesive regional planning.
- Upstream and Downstream Impact: Reduce upstream and downstream risks by implementing strategies that address the interconnectedness of watersheds, ensuring comprehensive flood risk management.
- Promote Sustainable Development: Integrate natural water systems with green spaces to create healthier, more livable communities.
- Community Engagement: Foster robust community engagement to ensure BGI solutions meet local needs and priorities, focusing on engaging residents, community leaders, and community-based organizations on flood risks, mitigation strategies, BGI projects, and available resources including flood insurance and stormwater management.
- Create a Replicable Framework: Develop an adaptable BGI Planning Framework that can be replicated in other communities across metropolitan Washington.
STAKEHOLDERS AND TIMELINE
Key stakeholders and partners include: COG, the District of Columbia, Prince George’s County, DC Water, and the U.S. Army Corps of Engineers. Community-based organizations, community leaders, residents, and youth groups are actively participating in the community engagement process.
The 15-month project will run from January 2024 until June 2025.
