Storm Water Utility Fee - 2024

The Village’s storm water management system prevents flooding, improves water quality, and complies with state and federal regulations. Due to the rising cost of maintaining the storm water management system, a Storm Water Utility Fee is being implemented starting in the first quarter of 2024. The user fee was determined to be the most equitable approach to storm water management versus a property tax increase.  

The Village’s monthly Storm Water Utility Fee is $5.74 per Equivalent Residential Unit (ERU).

One (1) ERU fee is charged per single family home, and other properties are charged based on the amount of impervious cover that they contain. Impervious cover is calculated based on the total area of hard surfaces like rooftops, driveways, parking areas, patios, and pathways on a property. Properties with more hard surface areas create more storm water runoff, and they are required to pay larger storm water fees (based on the number of ERUs that have been calculated).

ALL property owners with impervious surfaces (even those owned by tax exempt organizations like public schools, universities, churches, and other nonprofits) will receive Storm Water Utility Fee bills for months starting with January 2024.  

Responsible Rate Structure: 

  • $5.74 per month or $68.88 per year per Equivalent Residential Unit (ERU)
  • Mid-range compared to other local communities with Storm Water Utility Fees
  • All single-family residences pay one (1) ERU and the other properties pay based on impervious cover


  • Invoices for the Storm Water Utility Fee are sent out on a quarterly basis

How is the ERU value calculated?

The ERU value was calculated by averaging the impervious surfaces of single-family residential properties in Menomonee Falls. The measurements included the footprint of the home plus pathways, patios, driveways, garages, and any other buildings.

Calculations for ERU values are made using aerial imagery and computer software to determine impervious surface coverage. They will be updated as new developments are constructed in the Village.

  • 1 ERU = 3,725 square feet = the average impervious surface of a single-family home

Storm Water Utility Fees are itemized and included on the quarterly utility bill.
