(Columbus) Voters in the Columbus School District approved a $30-million dollar referendum that is intended to address elementary capacity, aging infrastructure, upgrades to the high school and the acquisition of land for future development. The mill rate is projected to increase by $1.62 meaning a homeowner with a property value of $100-thousand-dollars will pay $162 more per year. Voters in the city of Columbus in Columbia and Dodge counties, along with the towns of Columbus and Otsego, cast 1,879 votes in support and 1,095 votes against the referendum. District Superintendent Annette Deuman says the last three-and-half-years have involved a community led process which provided a community solution for the future of this Columbus School District. She adds that they are excited for the future.
