ROCKLAND, Maine — The city’s recreation center has undergone its share of renovations in the past few years, including a new roof, mold removal, a new floor, new locker rooms, a new game room and more. But all its problems aren’t fixed. On Nov. 8, the city’s voters will decide if the recreation center in the downtown area should borrow $675,000 to remove more mold from the building. The total bill, if approved, will edge over $900,000 with the estimated 3 percent to 4.25 percent interest rate on a 15-year bond.

A decommissioned walled-in chimney is causing trouble in the New Deal-era building. The wood surrounding it is moldy. It’s so wet that paint can’t stick to the brick walls on the other side of the chimney. The area was tested and has mold, but it’s not airborne yet, which makes it less dangerous for the children who use the building for after-school programs and other activities.

“We need the bond before this becomes a big issue,” said Rene Dorr, the city’s recreation director.

Aside from the mold work, the building also would get new energy-efficient windows if voters approve the bond.

The big fear, Dorr said, is that if this doesn’t get fixed soon the mold could grow and become airborne and then the building might have to be shut down.

When the work is done, the recreation center still will need more renovations to come into compliance with the Americans With Disabilities Act.
