The billing of all properties (residential or commercial) is based on impervious area. Impervious area is a term used to refer to hard surfaces on a property that do not allow rain to soak into the ground. Roofs, garages, carports, storage sheds, commercial buildings and concrete, gravel, or asphalt driveways, sidewalks, parking lots, and patios are all considered impervious areas.
The Stormwater Fee structure reflects the amount of runoff that each individual property contributes to the community's overall stormwater runoff. The more impervious surface area on a property, the greater the amount of stormwater that runs off into our culverts and streams, thus the greater the demand on the drainage infrastructure. The fee is set up so that properties that produce more runoff are assessed a greater stormwater fee.
