- Funding activities required by the federally mandated National Pollution Discharge Elimination System (NPDES) permit:
- to monitor for illicit discharges,
- conduct environmental education and outreach to the public
- control runoff from development
History
The City of Marysville established a surface water utility in 1999. The utility fee was collected by Snohomish County on property tax statements. Starting in 2007, the City began collecting the fee independent ofthe County. Therefore, the feeis no longer on a customer’s property tax statement, but included on their City of Marysville utility bill as a “surface water” fee.
How Rates and Fees are Determined
The fee is based on the area of impervious surface on a parcel. Single-family residents pay a flat rate, while non-single family parcels are assessed a fee that is calculated using an Equivalent Residential Unit (ERU).
An ERU is the average square feet of impervious surface on a single family zoned parcel in the city. In Marysville, average square feet of impervious surface is 3,200 square feet. The monthly fee is determined for a all other non-single family parcels by assessing the square footage of impervious surface on the parcel, and then dividing by 1 ERU (3,200 square feet), and multiplying by the monthly rate (See below).
Example of How the Fee is Determined
Non-Single Family Property:
- Total Parcel Size = 139,744 ft2 (red outline)
- Total Impervious Surface = 24,153 ft2 (red shaded area)
- ERU = 24,153/3,200 = 7.5 ERU
- Rate = 7.5 ERU x $12.43 = $93.23 per month
Single Family Property: All homes zoned as single family are charged a flat rate of $12.43 per month
