Non-residential property owners will pay based on the amount of hard surface or impervious area on their properties. The impervious area for all non-residential properties in the City was measured using aerial photography and a computer mapping software program.
The residential rate will be used in the calculation for non-residential properties. In the calculation, the flat residential rate equals one “equivalent residential unit” or ERU. One ERU=2,800 sq. feet of hard surface (impervious) area.
Non-residential property owners will be charged based on the number of ERUs of hard surface on their property. For example, if a commercial property has three times as much hard surface area as the average residence (8,400 sq. feet or 3 ERUs), its stormwater charge would be three times the residential rate per month. The rate per ERU that has been approved by City Council is: $2.95 per month per ERU.
