RE: 2015-2024 Stormwater Utility Fund Plan
Introduction
The Municipal Separate Storm Sewer System (MS4) general permit is mandated by federal reg-
ulations under the Clean Water Act and administered by the Minnesota Pollution Control Agency
(MPCA). The permit gives owners/operators of MS4’s, such as the City of Cottage Grove, approval
to discharge stormwater into lakes, rivers, and wetlands in Minnesota. MS4’s are regulated through
the use of NPDES permits. As a result of this unfunded federal mandate, the City of Cottage Grove
is required to clean and maintain ponds, stormwater structures, waterways, and ditches on a five-
year cycle. This includes minor maintenance and major maintenance projects. The minor
maintenance is typically completed by internal street division employees, and the major
maintenance is completed by hired contractors.
Effective August 1, 2013, the MPCA reissued the general NPDES/SDS permit for MS4’s. The City
of Cottage Grove submitted an application for reauthorization to the MPCA, and received notice of
coverage for the new five-year term on March 17. 2014. Included in the updated permit are new
requirements that the City must follow. The following is a list of the new requirements, which need
to be met within 12 months of the notice of coverage.
1. Prioritize public education efforts.
2. Post the MS4 permit application and SWPPP Document to the City’s website.
3. Prioritize areas that are likely to have illicit discharges and perform additional inspections in
those areas.
4. Develop written procedures for conducting illicit discharge inspections.
5. Update the City Ordinance on Illicit Discharges to meet the new MS4 permit requirements.
6. Develop written procedures for site plan review.
7. Develop written procedures for receiving public input.
8. Update the City’s Grading, Filling, and Excavation ordinance to meet new MS4 permit
requirements.
9. Develop a regulatory mechanism to allow the City to conduct inspections on privately owned
structural stormwater BMP’s, and assess costs of maintenance when completed by the City.
This is only for BMP’s constructed after the effective date of the new permit.
10. Complete an inventory of City facilities that can contribute to stromwater pollution.
11. Conduct quarterly inspections of City owned stockpiles and material handling areas.
12. Develop procedures to assess the treatment effectiveness of City owned stormwater ponds,
and provide a schedule of when the assessments will be completed.
13. Develop an employee training program for stromwater management that is commensurate
with each employees job duties.

Background
The City of Cottage Grove’s stormwater infrastructure currently includes 4,524 stormwater
structures/manholes, 450,947 lineal feet of storm pipe, 285 flared ends, and 122 stormwater ponds.
Cottage Grove also has approximately 88 miles of ditches.
The Stormwater Maintenance fund is used for the following expenditure items:
Public Works Personnel Services, which includes 3 stormwater employees.
Commodities, which includes operating supplies.
Professional Services, which include engineering services.
Minor Maintenance, which includes minor maintenance completed by Public Works staff.
Major Maintenance, which includes capital outlay projects and equipment.
Miscellaneous contractual services, which includes watershed district fees for South
Washington County Watershed District, the Education Coordinator, fleet costs, and other
small services.
Administrative and general expenditures for utility billing.
The City adopted the Stormwater Maintenance Fund in 2001 to help fund projects and improve
water quality and sediment control issues. The initial fee was $20 per year for a residential single
family home; this was increased to $21 in 2003.
On January 19, 2005, a Council Workshop was held to discuss the options for addressing the
backlog of projects in the Stormwater Maintenance Fund. The discussion focused on what accounts
for the backlog of projects in regards to minor and major maintenance, history of the fund, and
options to address the backlog. The City Council voted in favor of increasing the stormwater utility
fee for single family residential from $21 annually to $40 in the second half of 2005 and increasing
the fee in 2007 to $42 annually for single family residential. In 2008 the City Council increased the
fee to $48 annually for single family residential. The following table shows the annual fees per unit
of measurement.

2008-2013 Budget Review
When reviewing the stormwater budget from 2008-2013, an increase in expenses can be seen,
especially in 2011-2013. A major reason for this is due to large maintenance/construction projects
in each of those years, which include Pond C-P6, Pond L-P2, Cottage Grove Stormwater Utility
Improvements, and Cottage Grove Public Works Facility Improvements. Costs for these projects,
however, were not covered entirely by the City’s stormwater utility budget. Part of the funding for
these projects was covered by SWWD grants, as shown in the graph below. Even with these grants,
the stormwater utility fund is seeing higher expenditures than revenues. Consideration should be

costs.

Major Maintenance
When planning out major maintenance costs for the next four years, specific ponds were identified
that would require attention each year. These ponds would be included in the annual stormwater
maintenance project, which is one large project that the City contracts out each year. When looking
at the projected costs for these ponds, $75,000 should be budgeted annually. The City also
contracts out smaller projects throughout the year to address smaller issues that are discovered,
which should include $20,000. The final item that should be planned for is maintenance of the rural
stormwater system, which should include $20,000.
Other Annual Maintenance Items
There are several miscellaneous maintenance items that are completed each year, including street
sweeping at $25,000, emergency maintenance at $40,000, and televising/cleaning of pipes at
$15,000. Originally the budget included $20,000 for emergency maintenance, however, recent
trends have shown this number to be much higher than that. Due to this increase, the emergency
maintenance should be raised to $40,000 per year.

City Fee Comparison
The Stormwater Utility Fee for the City of Cottage Grove is currently $4.20 per month for single
family homes. When comparing this to the fees from 32 other cities, Cottage Grove is below the
average fee (shown by black line) for those cities.

Stormwater Utility Fee Recommendation
At the current City fee, the projected annual revenues for the stormwater utility fund are $670,954.
When reviewing the projected annual budgets for 2014-2018, this revenue is not sufficient to
sustain the stormwater program, even with capping the annual maintenance budget at $190,000.
With the average monthly costs of all cities at $4.37 per month, a small increase in the City of
Cottage Grove fee is recommended. An increase to $4.40 per month, or 4.8 percent, would raise
the projected annual budget from $670,594 to $706,689. This same rate increase of $4.80/year is
shown for 2016 as well, with a 4.5% per year increases in 2017-2024. The revenues also takes
into account projected housing increases each year.
