All single-family customers pay a flat fee based on the current monthly rate. The current monthly rate is listed on the bill. Multi-family units are charged the current monthly rate per ERU. Commercial customers' stormwater bills are calculated as follows:
Total annual fee = the (total impervious area) ÷ the base ERU (2,112 square feet) × (current approved rate/ERU/month) × (12 months)
The stormwater fee rate is reviewed and approved annually by City Council.
