The city of Belgrade has pushed the needle on the proposed Belgrade Aquatic Center by agreeing to support a “bond referendum proposal” if the nonprofit group spearheading the project can first raise approximately $2.5 million in private donations.

The city council voted unanimously Monday to sponsor a bond issue for construction of the facility if the nonprofit Belgrade Aquatic Center can first raise the private funds, estimated to be about 10 percent of the project’s final cost.
