ALEXANDRIA, Va. - The city of Alexandria will host its fifth community meeting on the Commonwealth, Ashby and Glebe Flood Mitigation Project on Thursday, June 4, from 7 to 9 p.m. at the Leonard "Chick" Armstrong Recreation Center, 25 W. Reed Ave. The meeting will also be held online via Zoom.
The session will feature updates on project design, utility relocation, the construction schedule and stormwater improvements, along with a question-and-answer period. Registration is required through a Smartsheet sign-up form.
The project will provide flood relief for the neighborhood near the intersections of Commonwealth Avenue and East Glebe Road, and Ashby Street and East Glebe Road. The proposed design includes new parallel relief sewers along Commonwealth Avenue and East Glebe Road to increase storm sewer capacity, a new outfall to discharge flows to Four Mile Run, and green infrastructure to provide a water quality benefit to the watershed.
The city has experienced repeated and increasingly frequent flooding in the area, which officials attribute to old infrastructure, the design criteria in place when the system was built and climate change. A 2016 storm sewer capacity analysis found the networks along Commonwealth Avenue and East Glebe Road lacked adequate capacity to handle runoff from recent intense storms.
The project is in the design phase, with an estimated total cost of $50 million funded through the Stormwater Utility and a Community Flood Preparedness Fund grant. Design is expected to be complete in early 2026, with utility relocations beginning the same year. Construction of the storm sewer system is anticipated to begin in spring 2027 and finish by summer 2030.
