What is Stormwater?
Stormwater is, in essence, just what is sounds like: water from a storm. Any precipitation that falls from the sky, including rain, hail, and snow, is considered stormwater. Please watch this video for further explanation.
Please find the Fiscal Year 2019 Annual Report HERE. Public comments are welcome. The report will be discussed at the September 24, 2019 meeting of the Sumner County Planning Commission.
The Sumner County Land Disturbance Permit Checklist and application have changed, effective July 1, 2019

Storm drains are NOT connected to the sanitary sewer system or wastewater treatment plant. Their purpose is to carry rainwater away from developed areas to prevent flooding. The water from rainfall, snowmelt, or irrigation that flows into storm drains goes directly into area streams and lakes.
How can this be a problem?
This stormwater can pick up debris, chemicals, and other pollutants as it flows into the storm sewer system and empties directly to streams, rivers, and lakes. The polluted water is called “nonpoint source pollution” which is the primary cause of water quality problems today.
How does this affect us all?
- The waterbodies where stormwater flows is used for providing drinking water, swimming, and fishing. Polluted water can have many adverse effects on people, animals, and plants.
- Polluted stormwater can affect drinking water sources. This can affect human health and increase drinking water treatment costs.
- Bacteria and other pathogens can wash into swimming areas.
- Hazardous wastes like auto fluids, pesticides, and solvents can poison aquatic life. People and land animals can become sick from eating diseased fish or ingesting polluted water.
- Debris--plastic bags, 6-pack rings, bottles, and cigarette butts--washed into waterbodies can choke, suffocate or disable aquatic life like birds, turtles, and fish.
- Sediment can cloud the water, destroying aquatic habitats.

Land Disturbance Permits
A Land Disturbance Permit is part of our MS4 (Stormwater) Program. It is a permit that allows you to begin excavation on your property. We issue Land Disturbance Permits for developments, residential projects, and utilities. It will be required that you have a Land Disturbance Permit if the soil disturbance is one (1) acre or more OR less than one (1) acre but the site is part of a large common development or subdivision.
If you need a Land Disturbance Permit for a development, please call our
office at (615) 451-6097.
