Stormwater run-off is rainwater and melted snow that runs off the surface of streets, lawns, farms and construction and industrial sites.
In undeveloped areas, much of the stormwater run-off is absorbed into the ground. That which is not absorbed by the ground ultimately flows into streams and rivers.
In developed areas, impermeable surfaces such as pavement and buildings prevent stormwater run-off from naturally being absorbed by the ground. Instead, stormwater, runs into storm drains, storm sewer systems and drainage ditches.
The excess stormwater run-off has the potential for causing infrastructure damage, downstream flooding and stream bank erosion. Bacteria and other pollutants not filtered from the runoff can contaminate streams, rivers, wetlands, etc.
Stormwater management addresses these concerns through strategic site design and measures to control run-off.
The Virginia Department of Transportation (VDOT) is committed to ensuring that stormwater runoff from all its roadways and facilities complies with all federal and state environmental regulatory requirements.
Public Education and Outreach
The following common activities have the potential to generate stormwater pollution:
- Disposing of trash and recyclables
- Disposing of pet waste
- Applying lawn chemicals
- Washing cars
- Changing motor oil on driveways
- Disposing paint and household chemicals
Individual behavior change can help control stormwater pollution. View the public service announcements below for helpful tips.
- Maintaining stormwater pollution reduction facilities
- Protecting Virginia's waterways
