Stormwater Utility

City Council approved the stormwater utility on Monday, October 9, 2017 after years of discussion. Beginning January 1, 2018, residents will pay between $1.77 and $5.31 each month, depending on which tier their property falls into. The four tiers are based on each residential parcel’s impervious area.  Non-residential property owners will also pay a fee based upon the impervious area of the parcel. The fee will raise $1.4 million each year to improve the City’s stormwater facilities. To find out which tier your property falls into, click HERE. A series of public education sessions to help residents and business owners understand the charge, and how it impacts them, were held late in 2017.

Stormwater Runoff Factor: .95
Effective Impervious Area: 5000 ft²× .95 = 4,750 ft²
 Parcel ESU: 4,750 ft²/ 1620 ft²/ ESU = 2.93 ESU
 Monthly Change: 2.93 ESU × $2.95 = $8.64
