Stormwater is runoff generated when rain (or the occasional snowmelt) flows over the ground.
Impervious surfaces like driveways, sidewalks, and streets prevent stormwater runoff from naturally soaking into the ground.
With roughly 50 inches of rain each year, the City proactively manages our stormwater through a series of 10,289 structures and 8,377 conveyances (pipes) that convey the stormwater into our streams, creeks, and ponds.
To get a better understanding of what the Stormwater Department oversees and manages, please read the Dunwoody Stormwater Extent of Service document.

Improving Water Quality
Stormwater is also very important as it relates to the quality of the water in our natural streams. As the stormwater flows over the streets, sidewalks, driveways, and parking lots it picks up and carries pollutants (like oil, lawn fertilizers, and litter) to our streams, creeks, and ponds. The City needs your help in order to improve our water quality and protect our natural water resources.
Be Part of the Solution to Stormwater Pollution
You can help improve Dunwoody’s water quality and protect our water resources in many ways:
- Don’t Dump Anything Down Storm Drains
- Clean up after Your Pet
- Don’t Pour Fats, Oils or Grease Down the Drain
- Try Recycling and Throw Litter in its Place
- Install a Low-Flow Toilet
- Do a Household Water Audit
- Create a Rain Garden
- Try Composting and Limit Fertilizers and Pesticides
- Recycle Your Motor Oil
- Inspect Your Septic Tank
The City of Dunwoody supports your decision to reduce erosion, and would like to assist by providing rock. In order to protect our environment and ensure proper use of municipal assets, the Public Works and Community Development departments require a signed Rock Request Application and Environmental Affidavit. The placement of rock within streams is a regulated process and will require permitting in many circumstances. For more information, please contact Public Works at 678-382-6850.
