View the Summary of Referendum Tax Impact from the District financial advisors, Piper Sandler.
In Iowa, agricultural land is assessed based on its productivity or use value rather than market value.
This video clarifies funding sources, dispels misconceptions, highlights how tax impact is calculated, and emphasizes the importance of maintaining school facilities.
The size and cost of the projects proposed in this referendum exceed the capacity of the school district's annual operating budget. While the district has effectively managed general upkeep and smaller projects over the years, larger initiatives, such as roof replacements and HVAC systems, typically require additional funding. Similar to how homeowners may seek loans for significant renovations, school districts often require a school building bond, which requires voter approval.
When costs are estimated at this stage, they are based off industry-wide database information (i.e. Mortenson, RS Means, etc.) that construction companies use, similar recently completed work by our partners, and at times, conversations with specific suppliers/contractors for specialized work. An industry-wide escalator is used to account for inflation and construction increases for work that would be scheduled out a year or more. If the referendum passes, bids are solicited from qualified companies by the school board and contractor/supplier decisions are made by the board.
