Environmental Stormwater Utility


Environmental Stormwater Utility Fund History
 

The Stormwater Environmental Utility Special Revenue Fund ("Fund") was created on August 25, 2008, with the passage of Ordinance No. 1168. Per the Ordinance, City Council must annually adopt a budget not later than the first day of each fiscal year (October 1st). Additionally, on or before September 15th of each year, the City Council must adopt a rate resolution establishing the stormwater fee for one equivalent residential unit ("ERU"). The stormwater fee cannot be more than the amount determined by dividing the budgeted cost for the City's stormwater environmental services for planning, administration, construction, capital improvements, operations and maintenance, extension and replacement, and debt service, by the sum of the ERU values of all the developed parcels in the City. 


What Are Your Stormwater Utility Fees Paying For?

The City's Lakes Management division is responsible for maintaining, repairing, and expanding the City's stormwater system while complying with Federal water quality mandates. The stormwater system is separate from drinking water and sewer systems.

Historically the City has been attempting to fund its Lakes Management and Stormwater programs, as laid out in the award winning Stormwater Lakes Management Plan (SLMP), through funds within the General Fund. Over the past few years it has become increasingly more difficult to continue the expected levels of service within this program solely utilizing General Funds. An ordinance has been proposed which establishes a special revenue fund for the stormwater utility that can only be used to cover the costs within the stormwater and lakes management program.

  2. Implement public education programs

  3. Implement public participation programs

  4. Implement business/industrial illicit discharge programs

  5. Implement construction site pollution prevention programs

  6. Implement post-construction control programs

  7. Implement municipal maintenance improvement programs

  8. Protect drinking water protection areas


Public Information

• Public calls/inquiries/outreach regarding general Stormwater Program/ Stormwater Utility Fee
• Print material, media outreach and interviews
 


Engineering and Project Management

• Technical Support for all stormwater program areas
• Plan Reviews
• Design reviews
• Field inspections and enforcements (~150/year)
• Drainage plan reviews annually
• Various neighborhood projects annually
• Structural and non structural project/program planning
• Ensuring consistent design criteria and standards
• Preparing accurate stormwater system inventory
• Assisting to install capital improvement project.


Utility Support

• Utility Support financial, personnel, work management
• Create and implement credit and appeals programs
• Complaint response
• Interdepartmental Coordination
• Supervisor and Administrative Oversight
• Budgeting and expenditure management


FY 2019 - 2023 Capital Improvements Program

The following is a narrative and summary chart detailing scheduled CIP projects including costs and an implementation schedule over the next five years.

FY 2019  

If feasible, construct Lake Nina and Lake Lily water quality projects.   Stormwater Drainage Rehabilitation Project - Tomahawk and Mohawk- this is a reconstruction/repair of a stormwater pipeline from Mohawk Trail to the headwater creek.  Reconstruction of the headwall and options for the treatment of runoff will be explored.    Feasibility determination for drainage lining project Kyle and Minnehaha circle, and Lake Minnehaha-Cheyenne Trail Nutrient Improvement project.  

 

FY 2020  

Conduct feasibility study on projects identified in the 2016 SLMP Update.  Easement acquisition and property owner coordination on feasible projects determined in 2019. This includes Kyle and Minnehaha circle, and Lake Minnehaha-Cheyenne Trail Nutrient Improvement project.   Construct projects identified in 2018 that proved feasible and property acquisition and property owner coordination has been resolved.

 

FY 2021  

Conduct feasibility study on projects identified in the 2016 SLMP Update.  Easement acquisition and property owner coordination on feasible projects determined in 2020.  Replace Stormwater Drainage Lining – replace the CIPP liner from Kyle to Minnehaha Trail.  This is the relining of existing stormwater infrastructure that has exceeded its normal life span.  Cheyenne Trail Nutrient improvement project (Lake Minnehaha) – Install nutrient reducing infrastructure in the stormwater system at Cheyenne Trail and Dommerich Drive to treat the stormwater runoff entering the Lake Minnehaha.

 

FY 2022 

Conduct feasibility study on projects identified in the 2016 SLMP Update.  Easement acquisition and property owner coordination on feasible projects determined in 2021.  Construct projects identified in 2020 that proved feasible and property acquisition and property owner coordination has been resolved.

 

FY 2023 

Conduct feasibility study on projects identified in the 2016 SLMP Update.  Easement acquisition and property owner coordination on feasible projects determined in 2022.  Construct projects identified in 2021 that proved feasible and property acquisition and property owner coordination has been resolved.

Rate Structure Methodology

Effective Aug. 27, 2018, the ERU rate to be charged for environmental stormwater utility fees for each ERU was established at $9.60 per month per Resolution 10-2018.

• Based on Impervious Area - area such as concrete which doesn't allow run off to penetrate
• 1 Equivalent Residential Unit (ERU) = 2,532 Square Feet of Impervious Area
• Fees Collected on Utility Bill

Rate Classes

Category Structure Size ERUs
Small Residential (1 to 2,166 sq. ft.) 0.7
Medium Residential (2,167 to 2,994 sq. ft.) 1.0
Large Residential (2,995 to 4,499 sq. ft.) 1.4
Consominium Residential Unit Parcel 1 condo or apartment 1.0
General Parcel* Any size SF of Imper/2,532
