$77.71M Project Adds Modern Facilities

The annex delivers approximately 75,000 square feet of educational space and was built by Technico Construction Services. It includes 18 general education classrooms, two special education classrooms, science laboratories, art and music rooms, a gymatorium, library, kitchen and dining areas, and an outdoor playground. The facility will also provide a pathway to the adjacent John Dewey High School, creating a connected middle-to-high-school campus for local students.
