Medina's Storm Water Utility

Storm Water is water generated by precipitation, which creates a runoff that collects surface pollutants such as fertilizers, car exhaust, and other damaging contaminants that are absorbed into the nearby soils, wetlands, lakes, and other important watersheds. It is known as a "non-point source" pollutant due to the nature of the generated waterflow. Controlling the runoff and aiding in water quality management has become essential in keeping our water safe for all of its many uses.

Why Must We Manage Storm Water?

The City of Medina administers, operates, and maintains a storm water management program meant to:

  • Preserve valuable natural resources
  • Protect people and property
  • Reduce nuisance flooding
  • Improve water quality

What are Some Current Examples of Projects in Medina?

The attached article provides some background and a few examples of where funds have been spent to provide a better understanding on the need for the storm water utility fee. - updated 5.28.2010

Financing a Storm Water Management Program

  • A Storm water program is funded by a service charge or utility fee
  • Augments existing funding sources
  • An equitable distribution of storm water management system costs, based on the premise of “contributors pay”
  • Fee varies by the amount of storm water runoff generated by a particular parcel

Medina's Storm Water Utility Billing

The purpose for creating the SWU is to provide an alternative source of funding from general property taxes to support storm water mandates and needs. Storm water mandates include the improvement to local impaired bodies of water (Lake Independence, Lake Sarah, Spurzem Lake, Holy Name Lake, Elm Creek, etc.) as well as the City’s Storm Water Pollution Prevention Program (SWPPP). Other needs include annual maintenance to City storm water ponds, culverts, erosion control and general enforcement. A Storm Water Utility (SWU) was officially established by the City Council on May 20, 2008.

For property owners who receive a water and sewer utility bill, a new line item for the storm water utility charge has been included on your monthly bill. Property owners who do not have water and sewer will receive an annual bill in the Spring.

The SWU will more equitably distribute charges for storm water improvements to property owners compared to general property taxes because the focus of a SWU is to better charge those who are contributing to storm water problems, rather than through property taxes which is based on your market value. Non-tax paying entities such as governments, churches, etc. will receive a SWU charge and bill. Some exemptions for parks, etc. and credits for wetland areas, as well as suitable conservation and buffer easements will apply.

Storm Water Fees

Purpose of the Utility Fee

Increased competition for City funding necessitates the need for a storm water utility to provide an equitable, dedicated funding source for storm water management services, including:

  • State storm water permit compliance
  • Implementation activities to address impairments of waters in and around Medina
  • Water quality improvements
  • Storm water system upgrades
  • General storm water system maintenance

Determining Fees

The fee for each parcel is based on the square footage and the number of units on the parcel. All parcels have been assigned a certain number of Residential Equivalency Factors (REFs). One REF represents the amount of runoff from a typical single family residential parcel. The assignment of REFs for some existing land use types is as follows:

  • Agriculture - 1 REF/10 acre1 round down to whole REF2
  • Commercial - 6.4 REFs/acre1
  • Industrial - 6.4 REFs/acre1
  • Multi-Family Residential - 5.3 REFs/acre1
  • Rural Residential - 1 REF/10 acre1 round down to whole REF2
  • Single Family Residential - 1 REF per parcel
  • Undeveloped Land - 1 REF/10 acre1 round down to whole REF2


  • 1 Billable acreage = parcel area minus wetland area
    2 Minimum of 1 REF per parcel

Calculating the Costs?

Total Number of REFs City-wide = 5,675
Estimated Storm Water Utility Budget = $163,925
Annual Cost per REF = $30.99
Monthly Cost per REF = $2.58
