NEW FAIRFIELD — Residents will sound off on the $109.4 million plan for a new high school and learning academy during a public hearing on Monday evening.

The proposal calls for building a new $79.3 million high school and a $30.1 million addition onto Meeting House Hill School. Pre-kindergarten through first grade would move out of Consolidated Elementary School and into the addition, while second-graders would go into an existing wing at Meeting House.

The district has applied for a state grant that would cover part of the cost. School officials have said the existing high school and Consolidated need millions of dollars worth of upgrades because they are in poor condition.

State Rep. Ken Gucker, D-Danbury, school board members and staff from the state department that oversees the grant are expected to attend, according to a press release from Gucker.

A referendum on the project is planned for next month.

The public hearing is at 7 p.m. Monday at the auditorium of New Fairfield High School.
