MEMORANDUM
TO: Honorable Mayor and Members of the Common Council
FROM: James Rabe, Director of Public Worksnc.-Z (/1
DATE: December 3, 2020
RE: Approve 2021 Storm Water Utility Rate ($210.60 / ERU / Year)
BACKGROUND
The City of Oshkosh (City) implemented a Storm Water Utility in 2003 to fund improvements to the
City's storm water management facilities. Based on the initial Storm Water Utility study completed in
September of 2002, the Common Council implemented a phased introduction of the rates. There have
been periodic subsequent rate increases, the most recent being to $196.92 per ERU per year in 2020. The
Storm Water Utility has funded several major projects to date, including:
• Tipler Middle School Area Dry Detention Basin
• North High School Area Wet Detention Basin
• Melvin Avenue Storm Water Pump Station
• James Road Area Detention Basin
• City Hall Underground Detention and parking lot project
• Armory Area Wet Detention Basin
• South Park Lagoon Retrofit
In addition to these major projects, storm sewers are replaced/upgraded with each street reconstruction
project.
The City experienced significant flooding during rain storms between 1990 and 2012. Localized areas
also flood during smaller storm events. In addition, the City is regulated under a Municipal Separate
Storm Sewer System (MS4) permit from the Wisconsin Department of Natural Resources (WDNR), as
mandated by the Federal Clean Water Act, for discharge of storm water to local water bodies. This permit
requires the implementation of practices to reduce the amount of pollutants entering lakes and rivers.
The largest expense item in the permit is reducing the Total Suspended Solids (TSS) generated by the
City as a whole by 20% in 2008. The City of Oshkosh has met the 20% goal. The Federal Environmental
Protection Agency (EPA), in conjunction with the WDNR, recently adopted targeted performance
standards within the Total Maximum Daily Load (TMDL) document that require TSS reduction of 48%
within the Sawyer Creek Watershed and phosphorus reduction of 83% across the entire municipal
system. It is anticipated these targeted performance standards will be implemented in the next couple
of years.

also flood during smaller storm events. In addition, the City is regulated under a Municipal Separate
Storm Sewer System (MS4) permit from the Wisconsin Department of Natural Resources (WDNR), as
mandated by the Federal Clean Water Act, for discharge of storm water to local water bodies. This permit
requires the implementation of practices to reduce the amount of pollutants entering lakes and rivers.
The largest expense item in the permit is reducing the Total Suspended Solids (TSS) generated by the
City as a whole by 20% in 2008. The City of Oshkosh has met the 20% goal. The Federal Environmental
Protection Agency (EPA), in conjunction with the WDNR, recently adopted targeted performance
standards within the Total Maximum Daily Load (TMDL) document that require TSS reduction of 48%
within the Sawyer Creek Watershed and phosphorus reduction of 83% across the entire municipal
system. It is anticipated these targeted performance standards will be implemented in the next couple
of years.
Brown and Caldwell has been retained by the City to update the City-wide plan for pollution reduction
in compliance with the EPA -approved TMDL. The City has also completed several flood studies and is
currently studying several watersheds to develop plans to reduce flooding in combination with pollution
control. City staff, based on information from all studies, developed a schedule of work needed to reduce
flooding and implement pollution control measures. The City is approximately one-third (1/3) of the
way through a thirty-five (35) year plan to implement these watershed plans, as amended from time to
time. The schedule calls for one (1) to two (2) major projects lobe constructed per year, with an emphasis
on flood control. Wherever possible, pollution control measures will be implemented with flood control
measures.
ANALYSIS
The City has worked with Ehlers (Financial Consultant) to perform a rate analysis to provide funding to
implement the projects outlined in the schedule, to implement other Capital Improvement Projects, and
to fund operational costs. In order to support these activities, a rate of $210.60 per ERU per year ($17.55
per ERU per month) is recommended. This rate will allow the City to complete all of the projects listed
in the 2021 Capital Improvement Program (CIP) — Storm Sewer Section, and also maintain daily
operations. The rate is proposed to be in effect on April 1, 2021. The Utility must retain adequate
reserves to maintain favorable bond ratings and meet the operating needs of the Utility.
In the event grants or other monies are secured at more favorable rates than anticipated in the study, the
rate increases for future years can be offset. The intent is to review the rate annually to incorporate
actual construction costs from the previous year and incorporate other funds that become available to
the Utility.
FISCAL IMPACT
The rate of $210.60 per ERU per year represents a seven percent (7%) increase, and is required to
implement all of the projects and operations in the 2021 budgets. Failure to adopt this new rate would
result in the delay of other proposed projects within the CIP. Pushing projects to future years will result
in less reduction of flooding during significant rain events prior to project completion and will delay
implementation of water quality improvements.

RECOMMENDATIONS
The Department of Public Works and Finance Department staff recommend a rate increase to $210.60
per ERU per year ($17.55 per ERU per month) to fund all activities in the approved 2021 budgets. It is
recommended the rate go into effect on April 1, 2021.
