SOUTH PORTLAND — The school department will host a public forum Oct. 5 to update the community on efforts to renovate or replace one or both of the city’s aging middle schools.

The meeting will run from 6:30 to 8 p.m. in the lecture hall at South Portland High School.

The Maine State Board of Education voted unanimously in August to put Mahoney Middle School on a list of projects that have been approved to receive state funding. The project’s cost, design and location have yet to be determined.

Mahoney, built in 1922 as the city’s high school, was rated No. 14 on a prioritized statewide list of proposed school construction projects that applied for funding in 2010-2011. Memorial Middle School, built in 1967, was rated No. 55 on that list.

Both schools have significant building problems and site limitations. School officials have started a complex 21-step process to determine the best and most cost-effective way to educate the city’s middle school students.

At the forum, school officials will explain the process and what must be done to receive state funding. Parents, students, staff members and others are urged to attend, ask questions and share ideas.
