Part 1: Just the Facts
In light of the upcoming City of Sun Prairie referendum, I wanted to share some facts and numbers with my fellow Sun Prairie residents. As a resident and an elected representative of District 1, the City has my vote on this. However, I’m writing now not to sway you, but to give you the facts you need before heading into the voting booth on April 7.
Let’s start with the obvious question: Why referendum? The City of Sun Prairie has reached the state-imposed levy limit, which only allows the City to raise property taxes by 2-3% every year, based on net new construction. Levy limits do not consider inflation and rising costs associated with a growing community such as ours.
Another question I’ve heard many times: Didn’t we just vote on a referendum? This is the first City referendum; previous referendums in Sun Prairie were school referendums. This operating referendum will be voted on by Sun Prairie residents on April 7th, 2026.
The vote is binding, City Council cannot increase property taxes beyond the levy limit, unless the referendum passes. Without the referendum, the City will face a $3.5 million structural deficit, requiring significant reductions or elimination of many city services and the layoff of staff.
• Referendum Survey: Last October, the City surveyed residents with a proposed referendum amount of $4.5 million. Since this did not receive strong support, the City went back and reduced the “cost to continue” component of the referendum by $1.04 million by implementing an organization restructure, which included the elimination of four management positions ($500k savings) and implementing an employee health insurance premium share ($540k savings).
• The updated proposed referendum amount is $3,950,000
• Component 1: $3,500,000 for “cost to continue” This is the amount needed to maintain current city services, after accounting for the savings noted above.
• Component 2: $400,000 for Public Safety, including two new firefighters, one new patrol officer, and increased wages for part-time firefighters.
• Component 3: $50,000 for a Part-Time Library Makerspace Coordinator. Referendum Cost: This would increase property taxes on the average single-family home in 2027 by $82/year. Over 3 years, the maximum increase would be $264, meaning that the amount of property taxes in 3 years could be $264 higher than today (i.e. $82 increase next year, $90 increase the 2nd year and a $92 increase in the third year, as an example). Please note, this is the maximum increase, the ceiling that City Council could increase property taxes.
Part 2: A Case for the Referendum
In my last letter to the editor, I shared just the facts and numbers regarding the City’s upcoming operating referendum on April 7th. Now I will make a case for the referendum.
A different kind of referendum
Sun Prairie residents are familiar with referendums, since this is the current model we use to support our schools. This is the first time in our history that the City of Sun Prairie is bringing an operating referendum to the voters. All previous referendums were school referendums.
Unlike school districts, which have a different funding formula, the City’s ability to fund services is strictly capped by a state-imposed “levy limit.” Currently, the state only allows the City to increase property taxes by about 2–3% annually, based on the value of net new construction within the City.
The problem is simple; inflation doesn’t care about levy limits. While revenue is capped at 2–3%, the cost of everything, from our snowplows, garbage and recycling pick up, police, fire and EMS to the health insurance for City staff, have all increased by much more than 3%.
We Heard You
When we first surveyed residents last October, the message from the community was clear: “Do more with what you have first.” We heard you. We re-organized and eliminated four management positions and implemented employee health insurance premium share for City staff, reducing long-term costs by over $1 million. However, bottom line, cuts are not enough.
The Cost of “No”
Since City staff accounts for about 80% of our budget and about 51% of the budget is public safety (police, fire and EMS), the $3.5 shortfall requires that we lay off staff and significantly reduce services. This would likely impact all departments, from public safety, the library, museum, parks, recreation & forestry, snow plowing, IT, finance, and administration.
Our first responders are already overworked. I recently did a ride-along with one of our amazing officers and learned that our officers are regularly required to work overtime to keep up with demand. In the last decade, fire responses in Sun Prairie have nearly tripled, and EMS calls have increased by over 107%. Our Fire and EMS chief regularly works 60-70 hours/week, including on his days off, to help relieve staffing challenges.
Calls for police service increased 13.5% between 2020-2024 and now average 70 calls per day. We are asking our public safety teams to go above and beyond to protect our city — and an investment in our Police and Fire and EMS departments is needed. A successful referendum allows for that, while a failed one does not. Without the two firefighters and one patrol officer included in this referendum, we risk longer response times when seconds matter.
Additionally, our library is a point of pride in our community, where my family and many other families go as a third place outside of work and home, to relax, meet other families, find good books, update resumes and find community. The part-time Makerspace Coordinator that is included in this referendum will help kids build skills and spark their interest in STEM, at a cost per resident of about $1.25/year. This is a worthy investment to finally open our Makerspace.
Putting it in Perspective
I am deeply sensitive to the rising cost of living. For the average home, the initial increase for 2027 will be about $82, roughly $1.58 a week. I have voted and will continue to vote to cut expenses where we can in each year’s budget.
Being an Alder comes with a fiduciary responsibility that I take very seriously. The City and City Council have reduced costs and consistently find budget efficiencies where we can and will continue to do so, while also providing a high quality of services for all of us who call Sun Prairie home.
On April 7th we are voting to sustain city services and increase public safety services to help our first responders. I ask that you join me in voting YES!
Whether you agree with me or not, I’d love to hear from you!
Do you have thoughts or questions about the referendum? I’d love to hear from you!
