Stormwater Improvement Projects

Fairfax County Stormwater Management is dedicated to protecting and restoring our vital natural resources through the implementation of stormwater management projects throughout the county.

Fairfax County restores streams to prevent erosion and reduce pollution that could hurt the Chesapeake Bay. Most of the streams in the County have a lot of erosion. By reducing erosion, stream restoration also protects roads, bridges, trails and public and private property. It also helps improve the environment. Stream restorations can help streams heal and are the most effective way for the County to meet state requirements.
