Westlawn Neighborhood Stormwater Improvement Project Study
Project Number: SD-000032-178
Project Update: 19 February 2026
A study is happening to check the condition of the stormwater pipes that run through the neighborhood and to understand how often flooding has happened and how likely it is to happen again. County workers and contractors will be doing surveys and talking with residents about flooding problems and past flood events. The project will continue until early 2027 and will include community meetings where people can talk about flooding and possible solutions.
Project Background
This project started because residents reported flooding problems. Many people said that water was flooding streets, yards, and even getting into homes. The county has already helped two homeowners protect their houses from flooding. Now, this larger project has been added to the county’s work plan for Fiscal Year 2026.
Project Description
As part of Fairfax County’s Flood Risk Reduction Policy, and because of repeated flooding complaints and a past County project to protect homes from flooding, staff from the Department of Public Works and Environmental Services are doing a Neighborhood Stormwater Improvement Project Study (NSIPS) in the Westlawn community.
They will study the private stormwater pipe system and flooding in the neighborhood to:
See if the pipes are in good condition and working properly.
Find ways to protect residents and help them prepare for future flooding.
Develop a long-term plan to keep the stormwater pipes working and reduce flood risk.
The main goals of the project are:
A County consultant, GKY & Associates, will inspect and analyze about 6,000 feet of underground private stormwater pipes to see what repairs or improvements are needed.
They will complete an NSIPS for the roughly 80-acre neighborhood to understand flooding problems and identify possible solutions.
County staff and consultants will work with community members to learn about their experiences and create a plan to improve how stormwater is carried away and to lower the risk of flooding.
Project Location
The project is in the Falls Church area. It is located south of Arlington Boulevard, north of Westlawn Drive and east of Wayne Road.
The project area is shown in orange.

Project Phase
The project is currently in the study phase. County staff and consultants are examining the stormwater pipes and flooding issues in the neighborhood. They will also speak with residents to learn about their experiences and discuss possible solutions. No decisions will be made about construction or next steps until after this study and conversations with the community are complete.
Project Benefits
The environmental benefits of the project are:
Ensure stormwater pipes are working.
Develop a plan to reduce future flood risk.
Help residents prepare to protect their families and homes from flooding.
Timeline
The project study will run through spring 2027.
What to Expect
County and consultant staff will be walking around the neighborhood and doing survey work during the study. They may use tools and equipment to help them inspect stormwater pipes and flooding areas. Community meetings and surveys will also be held so residents can share their experiences and ideas about flooding and possible solutions.
Project Cost and Funding Source
Money for future design and construction (such as repairing or replacing pipes or building new flood control features) is not yet guaranteed. It will depend on future county budgets and funding decisions. Stormwater projects like this are paid for through the county’s Stormwater Service District.
