PITTSFIELD, Mass. — City and school officials are expected to vote on a feasibility study for the Crosby Elementary School rebuild by Halloween.

On Monday, Superintendent Joseph Curtis gave an overview of the study's timeline and components. It would determine the feasibility of rebuilding Conte Community School and Crosby on the West Street site with shared facilities.

"We at this point, do not know the feasibility study will actually occur," he told the Middle School Restructuring Committee.

"There has to be discussions of the School Building Needs Commission, who is actually meeting [Tuesday night], there has to be discussion with the School Committee, and then finally, approval by the City Council by roughly Oct. 31 to fund the feasibility study."

The study, estimated to cost about $1.5 million, is a part of the 80 percent reimbursable costs from the Massachusetts School Building Authority, which accepted the project into its queue late last year.

The Crosby/Conte plan has the potential to house grades prekindergarten to first grade in one school and Grades 2 to 4 in another, with both maintaining their own identities and administrations.

Curtis explained that what begins now is a 270-day timeline with a "whole host of tasks" that have to be completed in that window.

"The Massachusetts School Building Authority (MSBA) Feasibility Study is a key phase in the process of addressing the needs of public school buildings in Massachusetts. It is a collaborative effort between the MSBA and the participating school district to identify the most appropriate and cost-effective solution to a school facility problem," an overview provided by the Pittsfield Public Schools explains.

"The Feasibility Study ensures that the district and the MSBA have a well-researched and collaborative plan for addressing the school facility's needs. It provides a framework for designing a solution that signs with education goals, meets community expectations, and is financially responsible."
