Create a stormwater utility that uses variable fees to incentivize stormwater infiltration, minimize the volume of and pollutants in runoff, and educate property owners and renters on the importance of managing stormwater runoff.
See Funding Stormwater Programs (US EPA: 2009) for a summary of stormwater funding mechanisms, including the creation of a stormwater utility district, to support grey and green infrastructure installation and maintenance.
For example, Minneapolis offers a credit system that allows one regulated entity, Murphy Warehouse, to save about $60,000 per year by managing all their stormwater on-site.
Create a legal stormwater utility with different fees (e.g., fees based on parcel size, income level, and on land use).
Achieve 1-star rating and offer commercial property owners decreased fees based upon an increased percent pervious surface coverage; provide education to property owners and renters on the importance of managing stormwater runoff in multiple formats and languages.
Achieve 2-star rating AND offer residential owners decreased fees based upon an increased percent pervious surface coverage; use 100% of fees for stormwater program.

Implementation details:
Bloomington has a credit program in which a user can provide documentation of the on site stormwater treatment and the city can recalculate the stormwater utility fee based on the information provided.
Part of the City’s Water Resources city plan also includes a stormwater utility that incentivizes stormwater management practices through variable fees. Education and outreach to residents is also part of this plan including working with residents building new structures and educating about the importance of proper management reducing nutrient loading.
The City has a stomwater utility credit option based on private property implementation of over and above stormwater management practices. Green Bay Packaging has taken advantage of this opportunity.
Duluth's stormwater utility uses variable fees to incentivize enhanced stormwater management to minimize the volume of runoff and pollutants that reach Lake Superior, and has a program to educate property owners. 100% of the fees are used for the stormwater program.
There are variable impact fees which must be paid by contractors for developing certain areas. The fees vary depending upon the area and impact. These fees, along with property taxes, fund stormwater maintenance, public education, as well as provide $30,000 to install rain gardens.
The City implemented a storm water utility by ordinance many years ago. In 2010, the City adopted a policy that gave property owners credit (reduction in their storm water utility fees) for implementing best management practices (BMPs) that provide for volume control, water quality via phosphorus reduction, and water quantity (rate control). All storm water utility fees are receipted in the City’s storm water enterprise fund (Fund 602) and used exclusively for storm water utility operating costs and infrastructure improvements.
The Environmental Utility Fund was started in late 2003 in response to local legislation that required the City to establish a program to meet permit requirements for the storm water system. The legislative mandate, called the National Pollution Discharge Elimination System (NPDES), is required of all storm system agencies within the state of Minnesota. To receive a permit, the City is required to provide an active program for management of the drainage system. This fee is the funding source for that program. The environmental utility is simply a method of financing the administration, planning, implementation, and maintenance of storm water best management practices.
Outcome measures/metrics/money saved:
This consistent, dependable revenue source provides a dedicated fund to manage the drainage system and water quality improvements without increasing property taxes or using assessments. A utility also provides the means to handle the increasing costs through small adjustments in the utility charges.
About the Fees and Expenses
Maplewood was one of the last area communities to implement this fee system. The state has allowed this type of fee to property owners since the early 1980s. The City of Roseville was one of the first to implement the fee in 1984.
The basis for the fee, rather than relying upon property taxes for the same expenses, is that the charge for the fee is based upon the amount of impervious surface on the property and the impact on the overall drainage system. Taxes are based solely on property value, which is not correlated to the needs of the drainage system. With a fee based on the amount of the utility used, similar to a water or sewer bill, the amount of the charge to properties is more equitable. The fee is also charged to non-tax paying properties which amounts to nearly 10% of the utility charge that would not be collected from non-tax paying properties.
The largest contributors to the Environmental Utility Fund are the Maplewood Mall and 3M. Both have the largest surfaces of pavement within the community and thus the largest impact on the services provided by the fund.
The major expenses to the fund are to pay for street sweeping, storm pipe maintenance and wetland/ponding area maintenance. In addition, the fund pays for programs to enhance wetland areas and improve water quality in our lakes and streams. The fund will create a funding source for upgrades and replacement of the storm drainage system that will reduce assessments to property owners.
On October 20, 2011, the City Council increased the EUF by 10%, which raises the quarterly rates for a single-family home from $17.13 ($5.71 per month) to $18.84 ($6.21 per month); a $0.57 per month increase. Demands on city resources for stormwater treatment and increasing operating costs made this increase important to the continued fiscal health of this fund.
The City of Marshall has a Surface Water Management Utility as identified by Chapter 78, Article III. of the City Code of Ordinances. The fees are variable and dependent upon land use and land size. Revenues derived from the utility are dedicated to the construction, maintenance, and operation of the storm sewer drainage system and for education of stormwater best practices.

The City's stormwater utility does charge variable fees that are designed to encourage the maximization of on-site treatment. The LEED-certified Best Buy Headquarters campus took advantage of the City's program.
On some redevelopments, the City offers incentives depending on what is being done on-site. This is determined on a case-by-case basis. For other developments, the City recommends that on-site BMP’s be installed, such as grit chambers or sump manholes, and then enters into a maintenance agreement where the City takes over the yearly maintenance and bills it back to the owner.
The City does have a Stormsewer Utility to improve runoff and educate residents. Larger contributors are incentivized to reduce runoff areas with reduced fees.
Rochester has adopted a Storm Water Utility Fee and Incentives Manual. The manual is accessible online at http://www.rochesterstormwater.com/SWUF_Credit_Manual_2009.pdf
The city's Surface Water Management Plan includes a storm water utility that uses variable fees to incentivize enhanced stormwater management, minimize the volume of and pollutants in runoff, and educate property owners. All fees received are used for storm water purposes. In some cases, parcels may be eligible for a credit to reduce their fee based on reduced stormwater runoff.
The City of Woodbury’s stormwater utility fees are set for residential (single family and townhome) parcels. Large multi-family, institutional, commercial and industrial parcels are variable based on impervious surface coverage.
The city also has a stormwater area charge for developing parcels for the construction of major city infrastructure. Developments can receive credits to these charges by providing all necessary stormwater basins and infrastructure required as a result of their development. All money collected from the stormwater utility fee and stormwater area charges are used to fund stormwater projects and stormwater projects are paid for only through these funds.
The City of Wyoming created and implemented a storm water utility in 2011 as part of the storm water utility report produced by WSB. The descriptive file attached contains the user rate structure determination. WSB has been contracted to update this plan in 2019.
Stated in Ch54: Stormwater Utility, actions have been taken to reduce the volume of and pollutants in rainwater runoff. Thus improving the quality of water runoff to lakes which helps recharge aquifers, control lake levels and decrease erosion and sediment to lake.
Section 700 of the City Code creates a stormwater utility. The Environmental Quality Commission has sponsored a public education program to educate residents on the importance of limiting what goes into storm drains (Storm Drain Baseball) as well as helpful hints on the city's website.
The City's stormwater utility fees are variable on residential, multi-family, institutional, commercial and industrial pacels. Fees are variable on all parcels with the exception of residential.
A storm water utility was adopted in 2010. Exemptions resulting in fee reductions may be granted provided a property owner meets certain storm water runoff volume and parcel area requirements.
The current City stormwater ordinance allows property owners to appeal stormwater rates the Director of Public Works to receive lower rates for improved pervious land or other stormwater mitigation measures adopted on their property.
The City of Inver Grove Heights adopted a stormwater utility with variable fees in 2015. Property owners are also offered decreased fees based upon percent impervious surface coverage.
The City of Pierz has implemented a Stormwater Utility. We collect fees from property owners in town to help maintain the stormwater removal system. Commercial rates are set by the amount of impervious area on the property.
The City of St. Cloud's Stormwater Utility has an important role in maintaining and improving water quality. The Stormwater Water System Use Code includes fee adjustment procedures to incentivize enhanced stormwater management. St. Cloud is an active member of the Central Minnesota Water Education Alliance (CMWEA) providing education outreach to promote water quality stewardship. Also, the City has a program that intends to reduce storm water pollution through employee training, proper materials handling, and fleet maintenance.
The City if St. Louis Park’s Stormwater Utility, Section 32-141, was established in the year 2000 to fund citywide stormwater initiatives.
Stormwater Utility rates are developed through the use of a residential equivalent factor (REF), which is a comparative ratio between the volume of stormwater runoff generated, based on average rainfall amounts, from specifically identified landuses. Stormwater Utility rates to be made against each property are determined by multiplying the REF by each parcel's acreage and the basic system rate. In addition, landuses that are not specifically identified within the REF can be reclassified by the probable hydrologic response.
City ordinance also allows for the adjustment of Stormwater Utility rates for specific properties based on hydrologic analysis, which is supplied by the affected property owner. Property owners may provide hydrologic analysis developed specifically for their property. If the results of the analysis demonstrate a significant different outcome than what is identified within the REF, the resident may receive a Stormwater Utility rate reduction.
A stormwater utility was created in 2006 with variable fees. From utility code: The city engineer shall, pursuant to the rules provided for herein, grant a credit to those owners or non-owner users of properties, against which stormwater charges are imposed, who employ structural or non-structural BMPs or other stormwater management practices on-site that significantly reduce the quantity or improve the quality of stormwater runoff from their property that enters the system.

Stormwater fees vary by lot size and percent of impervious surface.
Revenues derived from the municipal storm sewer utility shall be dedicated to the
construction, maintenance, operation, establishment and repair of the existing municipal storm
sewer drainage system and additions thereto.
The City has had a stormwater utility for a number of years. Rates vary based on the type of building on site. For instance businesses and industrial uses which have greater impervious surface pay a significantly higher fee (see page four of the attached rate sheet).
Cottage Grove's Surface Water Management Plan requires volume and rates to be controlled. If over used fees are required as a water quality cash dedication as a way to minimize the impacts of development and manage stormwater quality and runoff control. If an applicant is unable to meet the volume control standards the applicant will pay a cash dedication for mitigation. The cash dedications help to finance the system requirements related to stormwater quality and runoff volume control within the City.
The City of Mankato storm water drainage utility was established 7-12-2004 and is operated as a public utility pursuant to the City Charter, City Code and applicable statutes. The revenues therefrom are derived subject to provisions of this section and Chapter 444, Minnesota Statutes. The storm water drainage utility is part of the Public Works Department and is administered by the City Engineer.
Storm Water Utility:
Cost of service $3/month
Commercial units, for each 1,000 square feet over 10,000 square feet $ .75/month
We are currently working on a study of our stormwater utility fee to see if it is sufficent and determine more effective ways to utilize this fee while using the data from the study to educate our staff, council and citizens about Mankato's Storwater needs.
We have a storm water utility fee.
We do not have a fee reduction program.
The residential fee is a flat rate of $10.21
The commercial fee is variable and is based off the amount of impervious area divided by the average residential impervious area. When you get a base unit it is multiplied by $10.21
Some of the storm water fee is used for flood mitigation.
Section 14-50 (11) of the City Code establishes a stormwater utility that uses variable fees. The city's website has educational materials on the "Watersheds" page. At the April 13, 2015 City Council Work Session, the city committed to replacing its street sweeper with a waterless MacQueen Equipment model that minimizes the amount of pollutants in runoff water entering ponds and lakes. The city uses the sweeper for city-owned parking lots, clean up of accidents or spills on city streets, and removal of debris from the surface of storm water catch basins.
In section 52 of the City Code, fee calculations are shown for stormwater. These fees are determined on a variable basis that has much hire fees for uses that have high impervious surface, rewarding more pervious area with lower fees.
The City of Rogers currently has a variable stormwater utility fee for all commercial property. The rate is based on the size of the parcel, the amount of impervious surface, and the land use zone.
The City is currently in the process of developing a Stormwater Utility Credit. The credit will offer property owners the opportunity to receive a reduction on their Stormwater Utility Fee for implementing BMPs on their property.
Currently, all of the fees that the City receives from the Stormwater Utility Fee is used for the stormwater program. The fees from residential parcels cover the fee that the City owes to the Elm Creek Watershed Management Commission. The fees from commercial parcels are used towards stormwater pond clean outs and other pond maintenance, along with the material costs and salaries of the stormwater department.
The City has created a stormwater utility that uses variable fees to incentivize enhanced stormwater management, minimize the volume of and pollutants in runoff, and educate property owners. For details see: http://stpaul.gov/index.aspx?nid=75
The city of Saint Peter's stormwater utility is committed to the preservation and enhancement of citizen's quality of life through water quality improvement, drainage infrastructure management, flood hazard minimization and public awareness. Stormwater payment goes toward maintaining and enhancing storm sewers throughout the community. Some of the more noticeable stormwater management efforts include maintenance of catch basins that catch the flow of water from streets and stormwater basins that hold stormwater for longer periods and allow for natural treatment and replenishment of aquifers. Several educational materials and online resources are frequently posted on the city's website for citizen's education and awareness.
The City has adopted a surface water utility fee to fund repair and replacement of existing
conveyance systems and provide a funding source for implementation of goals listed in the
SWMP and BMPs listed in the SWPPP. Estimated operating costs, capital costs, and debt
payments for insuring the integrity of the system are included in the City’s Comprehensive
Infrastructure Replacement Plan and Policy, with a time horizon of 50 years.
The Surface water utility fee varies with household type.
