Stormwater Management

Stormwater runoff occurs when rain or snowmelt flows over the ground. Hard surfaces, like roofs, driveways, parking lots, and streets prevent stormwater from naturally soaking into the ground. If not managed properly, stormwater runoff can create stormwater pollution and/or flooding issues.

What Do We Do?

The Stormwater Management Program helps protect water quality in the City. The program has three focus areas: 1) Stormwater Quality, 2) Flooding and Drainage Issues, and 3) Public Infrastructure Maintenance & Operations. Residents also partner with the City to protect water quality and decrease the impact of flooding. Working together we can manage stormwater more effectively to protect our local water resources and our community.


.

The City has adopted a Stormwater Utility Fee to provide funding for the stormwater management program to reduce the impact of stormwater pollution and flooding, and ensure that Alexandria is in compliance with state and federal stormwater regulations.  


.

Our everyday activities can impact stormwater quality in positive or negative ways.  It’s up to all of us to do our parts. Learn what you can do to get involved and help out around your home, yard, or business to help improve water quality in our local streams, the Potomac River, and the Chesapeake Bay.  


.

Stormwater carries pollutants from hard surfaces to our local waterways, and can contribute to poor water quality.  Learn more about stormwater quality, what stormwater BMPs are, and what the City is doing to protect our local streams, the Potomac River, and the Chesapeake Bay.  


.

Flooding is the number 1 natural disaster is our country.  Learn more about what the City is doing to help improve flooding and drainage issues and how you can be flood smart and what you can do to help protect your property.  


.

Maintaining the storm system is a big job. Learn about what it takes to operate, maintain, and repair over 210 miles of streets, 185 miles of storm sewer pipes, 13,500 storm sewer structures, and hundreds of stormwater BMPs.
