LISBON – Voters defeated three of five bond questions Tuesday, including one for $500,000 to design a new high school.

The other two losing propositions were $369,145 for public works equipment and maintenance, and $320,000 as a match to build and maintain the Androscoggin River Trail. The public works money would have paid for a front-end loader, two dump bodies and a compactor container, plus repairs to concrete blocks at the garage.

The majority of the 1,392 residents casting ballots said yes to a $916,855 bond to fix town roads and $394,000 in matching money for reconstruction of Upland Road by the Maine Department of Transportation.

The Lisbon Town Council and the Advisory Board had recommended passage of all five bond questions.

School Committee Chairwoman Prudence Grant was in disbelief at the school bond failure Tuesday night. The vote was 902-486.

“I’m just stunned; devastated. I was so surprised,” she said. “I cannot believe what the voters did. I’m very certain we will lose our accreditation.”

Grant said a recent letter from an accrediting panel stated the committee has to respond by May 15 on steps it will take to rectify problems, such as an old heating system and lack of sprinklers in part of the building.

Lisbon High School opened in 1952 and educates students in grades nine to 12.

Grant said the school’s five-year accreditation is due next year.

“We can file an appeal, but there’s no way we can do that by May 15, or even early September,” she said.

As of June 30, the school system will stand alone because efforts to consolidate with other towns, as mandated by the state, have failed.

Grant said the School Committee will meet in a week, but she has no idea what the next step will be.

“Voters have no idea of what they have done,” she said.
