Project Description
The Bellefonte Avenue Storm Drain Improvement project will reduce flood risk for homes within East Bellefonte Avenue, East Howell Avenue, and Clyde Avenue by improving the local drainage system. The project consists of upsizing and relocating the storm pipe currently beneath homes between East Howell Avenue and East Bellefonte Avenue to the right-of-way along the gravel alleyway. Additionally, the existing inlets will be replaced by larger ones to provide greater capacity at the E Bellefonte Avenue low spots. The work will also consider realigning storm drains where necessary.
Project Background
The City has been experiencing widespread flooding due to an increase in high-intensity rainfall events, which are attributed to climate change. As a result, residents of Bellefonte Avenue have been facing frequent localized flooding. Several residents have reported in-home flooding because the current curb inlets are unable to capture the excess water. These frequent flooding incidents support the findings from the City of Alexandria’s Storm Sewer Capacity Analysis (CASSCA). This increased flooding is attributed to old infrastructure, the design criteria in place at the time of construction, and the impact from climate change.

Planning
The Bellefonte Avenue Storm Drain Improvement project planning phase is complete. The investigation of neighborhood flooding study is now available, which includes site evaluation, CCTV inspection, hydraulic modeling verification, solution development and cost estimates. The project will be in the design and construction phases once the project budget is available. The estimated timeline for design is FY2025 and for construction FY2026.
Design
Design Update
The investigation of the Bellefonte Avenue neighborhood flooding Study is complete, and the project is currently in the design stage. The City is in the process of procuring a design contractor to produce the construction drawings. Upon awarding a contract to a design firm, the City plans to meet with residents and stakeholders. Notices will be distributed to residents before the start of work.
