Stormwater Utility Fee
Stormwater Utility Fee Rates
Effective July 1, 2023
Stormwater utility fees are based on the total amount of impervious surface on an individual lot or parcel.
Most stormwater utility fees billed on water and sewer accounts will be changed from annual to monthly billing. Residents will receive 12 smaller stormwater utility fee charges instead of one large fee each year. Monthly billing should make it easier for property owners to plan monthly household budgets and less fluctuation in utility bill amounts. There are no additional fees for paying monthly or annually.
Starting July 1, 2023, stormwater utility fee rates will increase according to Ordinance 16149. The fee for residential property owners will increase between $0.75 and $3.11 per month and the fee for non-residential property owners will increase $1.55 per Equivalent Residential Unit or ERU (one unit equals 2,400 square feet of impervious area).
The stormwater utility fee pays for repair, operation, and maintenance of the public drainage system. It also funds programs that improve water quality in streams and lakes. The increase supports funding of projects that help the City comply with the Falls Lake Nutrient Management Strategy and Total Maximum Daily Loads (TMDLs) pollution reduction requirements. This includes funding for the South Ellerbe Creek restoration, algae floway project, and TMDL projects for bacteria in Northeast Creek and sediment in Third Fork Creek.

See Your Impervious Area
The Public Works GIS Billing Data Group maintains over 1/2 billion square feet of impervious surface area within Durham city limits. An average of 2.5 million square feet of impervious area is added each year as a result of construction and redevelopment.
The amount of impervious surface area on a property is the single most important factor affecting the amount of water, including pollutants, flowing off a property.
