How much is the service fee?

Equivalent Stormwater Unit (ESU)

Equivalent stormwater unit (ESU) means the average impervious area of residentially developed property per dwelling unit located within the city and established by city commission resolution.  An impervious surface is a surface that will not allow water to pass through to the soil.  Rooftops, driveways, parking lots, and pools are typical examples of impervious surfaces.  ESUs were developed by field verification of open space and impervious surfaces on an average home lot.  The service fee, which is not a tax, is billed monthly with the other city utilities. 

A single-family parcel fee is based on the number of ESUs that exist.  The utility costs were distributed equally to the parcels.  Commercial units are based on how many ESUs are on the property.
