The following table shows the annual fee, devised via a Stormwater Management Utility Rate Study. The study employs an impervious surface model utilizing, impervious ft2 ÷ 2,760 ft2/(ERU Fee) calculation, with modifiers and variables for agricultural land, forested land, and undeveloped land.
Example: A parcel containing 915,447 ft2 (21.01 ac.) of impervious surface
915,447 ft2 ÷ 2,760 ft2 / ERU = 331.68 (rounded to nearest ERU = 332 ERU) 332 ERU x $36.00 / ERU = $11,952/year
| Property Class | Base ERU |
| Single Family Residential | 1 ERU/Unit |
| Nonresidential (Commercial/Industrial) | Impervious ft2 ÷ 2,760 ft2/ (ERU Fee) |
| Multi-family | Impervious ft2 ÷ 2,760 ft2/ (ERU Fee) |
| Mobile Homes | 1 ERU/Unit |
| Tax-exempt and Non-profit | Impervious ft2 ÷ 2,760 ft2/ (ERU Fee) |
| Vacant/Undeveloped | Not Assessed |
| Monthly ERU Fee | $3.00 |
| Annual ERU Fee | $36.00 |
| *for parcels containing multiple residences on the parcel, an annual fee per unit will be assessed | |
