What Is Stormwater Runoff Pollution?

Every day, trash, oil, sediment, chemicals, bacteria, and other pollutants collect on our rooftops, roads, parking lots, and driveways. When it rains, the pollutants travel over these surfaces, flow into the storm drain system, and in great volume end up in our creeks, rivers, lakes, and streams. Below are some common sources and concerns for each type of pollutant.

Can the Fee be Modified or Reduced?

Property owners that retrofit their property with approved Best Management Practices that improve the quality of stormwater discharged from their property can receive up to a 100% reduction in the impact fee. Additionally, under the rebates program, the County will provide a limited amount of rebate funds each year to property owners to retrofit their properties. If there is an error in the way the County calculated the fees, an appeal can be made to the Department of the Environment.
