What determines the amount of my stormwater fee?

The fee is based on two factors, the size of the parcel and the amount of impervious surface (roofs, driveways, etc) on it. In general, property owners are charged $2.25 for every 1,898 square feet of impervious surface. If the parcel has no impervious surface or has a high ratio of pervious to impervious surface, a runoff coefficient is used to estimate how much of the property generates runoff. Chapter 918 explains in detail how the fee is calculated.
