Casco residents will be asked to again approve borrowing for two town building projects at a special town meeting at 7:30 p.m., Aug. 18, due to an error in the warrant for the annual town meeting.

The special town meeting was scheduled at Tuesday’s Board of Selectmen’s meeting, during which Robert Levesque asked for clarification on how to go about gathering signatures to place two questions on the November ballot.

Levesque’s wants voter approval for another property revaluation and to allow the recall of town officials.

Selectmen also discussed regionalization of public safety services and set a vote for Tuesday, Aug. 12, to potentially switch from Naples Public Safety to the Cumberland County dispatch center in Windham for handling emergency calls.

Partly because this year’s town meeting warrant included two citizen petitioned articles, the warrant lacked a signature from Town Manager Dave Morton, who needed to sign in his role as the town treasurer as well. Due to this error, residents need to vote again to allow the town to borrow money to renovate the Casco Community Center and convert the Casco Memorial School into town offices.

The amounts set at the annual town meeting will stand – $210,000 for the Casco Memorial School and $750,000 for the Casco Community Center, plus interest.

The special town meeting will be held at the Casco Fire Station on Meadow Road.

While Morton explained that the special town meeting was necessary to borrow money for the two projects already approved by residents, resident Wayne Ward opposed the meeting, saying the town could save money by waiting to put the question to a vote in November.

The selectmen voted 4-0 to hold the meeting and recommended a yes vote to authorize borrowing.

Morton also detailed progress in designing the renovations for the Community Center, saying a draftsman is currently working on drawings. Morton said he would have something for the board to examine in a week or two. After approving the drawings, the next step would be to put the project out to bid.

Morton said the draftsman will also work on drawings for the Memorial School, but started with the Community Center because the town needs to vote to accept the school from School Administrative District 61 before renovations can begin.

Levesque, founder of the Casco Tax Fairness Association came to the selectmen to clarify requirements to gather signatures to put questions on the November ballot. He and the association members are unhappy with assessments on their waterfront properties from the 2007 revaluation.

The association is now appealing 220 abatement requests rejected by John O’Donnell, the Casco tax assessor, to the Cumberland County Commissioners.

Levesque and Morton said that state petitions require those who collect signatures to sign an affidavit that they did their job correctly. At the town level, though, selectmen can decide whether or not to require this step.

Petition circulators are supposed to ask signers if they are registered voters in Casco and watch them sign. Levesque said he wanted to know in advance if the board was going to require certification, as he was working on a tight time schedule.

“It’s only fair that I know up front,” Levesque said.

Selectman Susan Witonis said she would like to see petition circulators sign an affidavit, citing recent debate elsewhere about rules for collecting signatures.

“For your benefit and ours,” Selectman Barbara York said. “The certification makes it more legal.”

On the topic of public safety, Selectman Calvin Nutting said he thinks the town is paying too much for dispatch services. The town currently pays $30,000 a year for Naples dispatch services, which also serves Raymond and Harrison. Cumberland County quoted $20,000-22,000 a year for dispatch services. Nutting made a motion to switch dispatch to the county.

Witonis agreed but added that she thought they should tell Casco public safety personnel before the vote so they could give feedback to the board. York said she wanted to notify Naples and Raymond as well.
