Project Summary
Phase: Construction
Status: Active
Location: Potomac West
Managing Dept.: Project Implementation
Sponsor Dept.: Transportation & Environmental Services
Project Description
The Mt. Vernon Cul-de-sac Inlets and Alley Improvements Project will provide flood mitigation for townhomes on the 100 block of Mt. Vernon Avenue. Inlets and underground storage vaults will be installed on Mt. Vernon Avenue and it's adjacent alleyway to capture and attenuate storm water runoff. The addition of new underground utilities will require the relocation of the local water utility. In tandem with work, the alleyway will be re-graded to improve surface drainage into the downstream swale.
Progress Update
January 2025
The relocation of the waterline on Mt. Vernon Avenue is scheduled to begin in February.
In January, the City’s municipal water service provider will distribute detailed notices outlining the planned relocation work. Before construction begins in February, impacted residents will receive "Code Red" notifications through text messages, emails, and phone calls.
The waterline relocation work will occur within the public right-of-way and is anticipated to be completed by May. All activities will comply with the City’s construction ordinances.
The City will host a public meeting to provide an overview of the project scope and construction timeline before the project begins.
The City is committed to minimizing construction impacts as we undertake essential storm sewer improvements. City staff encourages residents to stay informed. Thank you for your patience as we work to improve our infrastructure.

Construction Phase Background
November 2024
The City has been addressing the feedback residents provided during the pre-construction kickoff meeting in October. City staff are investigating options to reduce parking and trash collection service impacts on residents.
Utility relocations within the City's right-of-way are planned for early 2025 to accommodate the proposed underground runoff storage vaults and the new storm sewer pipes.
The City will continue to coordinate with utility providers and residents to prepare for construction. Revised plans are expected in January 2025.
October 2024
The City is preparing to advertise the construction services solicitation for the Mt. Vernon Cul-de-sac Inlets and Alley project. In tandem with the final approvals process, the City is coordinating with impacted utility providers to finalize relocation plans. Utility relocations are expected to begin in early 2025 and conclude within Q2 of 2025. Public notices to impacted residents will be issued by the utility providers prior to any service disruptions.
The City hosted a public construction kickoff meeting in late October to announce the start of the construction phase, present anticipated impacts to residents along the 100 & 00 blocks of Mt. Vernon Avenue and answer questions about the project.
Meeting invites were issued prior to the public meeting. Meeting materials and information can be found under the Community Engagement menu at the bottom of the page.
