Voters in the Denver and Dike-New Hartford School Districts Tuesday approved bond issues for proposed facility upgrades.

Denver residents passed a $7.5 million referendum that will help finance construction of a new middle and high school and improvements at the current elementary building. Approving the measure allows work to begin on a new addition to the Cyclone Center, an art and athletic facility that was built on in Denver after passage of a 2016 referendum. Tuesdays bond issue passed with 85-percent voter approval (1009-Yes, 176-No).

Dike-New Hartford voters favored a $9.4 million bond issue that will help finance upgrades and additions to the Dike and New Hartford buildings. The complete $17.9 million project includes a complete renovation of the high school, along with the construction of a new gymnasium. Classroom expansion and securing facility entrances are also part of the project.

Voters also passed referendums on revenue purpose statements in six northeast Iowa school districts: Waterloo, Cedar Falls, Edgewood-Colesburg, Independence, Starmont and Waverly-Shell Rock. Each district will be allowed to access funds put aside by the state to pay for new equipment and building improvements.
