Alexandria makes progress on two major flood mitigation projects

Some of the city’s biggest flood mitigation projects have been making progress in recent months.

In the same Flood Action Alexandria newsletter that highlighted some record-breaking rainfall in July, the city said two of the top-ranking, large capacity flood mitigation projects have “reached notable milestones.”

The first is that a firm has been selected to handle the project at Commonwealth Avenue and East Glebe Road/Ashby Street and East Glebe Road, two separate plans mergedearlier this year into one $50 million project. The city is currently in negotiations with the selected firm.

According to the newsletter:

The project, which combined two projects in adjacent neighborhoods, will increase the capacity of the storm sewer system to allow stormwater conveyance. The project will also incorporate low impact development elements — commonly referred to as “green infrastructure” — to allow stormwater to soak into the ground to reduce runoff. A grant from the Virginia Community Flood Preparedness Fund awarded to the City in October will support portions of these projects. The estimated cost for design and construction is $50 million.

The second project is the Hoofs Run culvert bypass, and the newsletter says the city hasn’t selected a firm yet but has narrowed its list of qualified contractors.

“The project will carry water from Timber Branch in a new stormwater management system that involves conveyance to improve the system’s performance and reduce flooding,” the newsletter said. “The estimated cost for design and construction is $60 million.”

More information on both projects is available on the city website.
