Potomac Waterfront Flood Mitigation Study
King, Strand, and Union Streets Nuisance Flood Mitigation Information
A study was conducted to evaluate flooding conditions and to identify feasible flood mitigation alternatives along the Potomac River. The City of Alexandria engaged URS Corporation to provide technical assistance with this study.
The study considered both nuisance flooding which is generally caused by high tides, as well as extreme flooding up to the predicted 100-year water surface elevation. A wide variety of alternatives, such as flood barriers and flood proofing, were considered to mitigate the flooding problems.
The study concentrates on evaluating solutions and recommending the most effective solutions. The study also summarizes the detailed engineering assessments conducted as part of the feasibility evaluation of potential measures and recommends cost effective solutions that consider historic/archeological resources, business/tourism impacts, and environmental impacts.
Flood mitigation, as described in the Potomac Waterfront Flood Mitigation Study, was included in the approved Waterfront Small Area Plan and implementation of the Plan’s recommendations will be developed during FY2013
This study encompasses the entire Potomac River waterfront from the Capital Beltway north to approximately Bashford Lane extended. The figure below illustrates this area.
