Our Stormwater Management Program protects water quality in 800+ miles of streams. We protect property from flooding through planning, maintenance, water quality assessment, and pollution prevention, reporting and enforcement. Storm drains lead to streams, not a wastewater treatment facility. Your actions impact local watershed health and the Chesapeake Bay.
A watershed is an area of land that drains to a particular water body, such as a lake or river. No matter where you live, work, or play you are within a watershed.
From your backyard to the Chesapeake Bay, what occurs in your neighborhood affects the water quality downstream.

Fairfax County studies stream health by monitoring living and non-living parts of our freshwater ecosystems. This information helps assess the condition of our watersheds and guides efforts to protect and care for our local freshwater resources.
