Stormwater Utility Fee

Since January 2002, residents and businesses in the City limits have been required to pay a Stormwater Utility fee, which provides revenue of approximately $3 million per year (75% is used for flood control projects and 25% is used for the Stormwater Permit).

The fee is based upon the amount of area on each property that does not allow water to absorb into the ground, such as driveways, patios, and rooftops. The approved monthly Stormwater fee is $0.00152 per square foot ($1.52 per 1,000 square feet) of impervious area.  Because utility bills are sent every other month, the charge on the bill represents two months.  Below are examples of fee calculations for residential and commercial properties.

Residential Example, Single Family Residence:
An average single-family residence contains a little over 2800 square feet of impervious area, which may include patios, driveways, and rooftops. The Stormwater Utility fee for this residence would be $4.26 each month, or $8.52 per bill.

Commercial Example, Office Building:
A medium-sized office building containing approximately 64,000 square feet of impervious area, which may include rooftops and parking lots. The Stormwater Utility fee for this commercial establishment would be $97.28 each month, or $194.56 per bill.


The Stormwater Utility Annual Reports describe the activities conducted using the Stormwater Utility funds.
