It’s election day in Maine, and polls are opening across the state to give registered voters a say on local school budgets and on a $50 million state technology bond.

Some communities also are having special municipal elections, such as a vote on a proposed new police headquarters in Wells and a new school in Brunswick.

If the state bond proposal is approved, $45 million would be distributed in competitive matching grants to support infrastructure, equipment and technology upgrades for public and private entities involved in certain technology sectors. Grants would be aimed at the biotechnology, aquaculture and marine technology, composite materials, environmental technology, forestry and agriculture, information technology and precision manufacturing sectors.

The remaining $5 million in the bond would be used to recapitalize the Maine Venture Fund, administered by the Finance Authority of Maine. The fund invests in small businesses that show the potential for growth and public benefit.

The bond is projected to potentially cost taxpayers $63.7 million after interest is included over its 10-year repayment schedule.

Maine voters typically support bond referendums and there has been no organized public opposition to the current proposal.

School districts are seeking voter approval of budgets for the fiscal year that begins in July.

Most proposed budgets are coming with spending increases and tax increases, although there is still a chance that communities could see an unexpected boost in revenue from the state depending on the outcome later this month of budget battles in the state Legislature.
