How is the fee determined?
Typical Single Family Home Example:
Calculate the total square feet of impervious area
1,100 sq ft (roof)
+ 750 sq ft (driveway)
+ 300 sq ft (patio)
+ 100 sq ft (sidewalk)
2,250 sq ft total impervious area
Calculate the corresponding SWU fee: the total square footage of impervious surface is multiplied by the rate ($0.02004/sq ft)
2,250 sq ft × $0.02004/sq ft = $45.09/year
Compare the calculated SWU fee with the annual cap fee for your property type. (See the cap fees rate table below). The amount you pay is the lesser of the two.
The calculation above does not apply for multi-family properties such as apartment complexes, or condominiums. In this case, the SWU fee calculated in step 2 is divided by the total number of existing units.
The stormwater utility cap fees will remain in place for the 2015 fiscal year. These cap fees were determined by calculating the average fee per property classification type as determined by the Assessor's Office. The stormwater utility account type cap fees are listed below.
