Updated Plan: Rebuilding and Renovating the Middle School On Site

As part of the community outreach effort following the unsuccessful April 2026 referendum, feedback gathered through focus groups and other community engagement identified concerns regarding the proposed relocation of the War Memorial to accommodate construction of a new middle school at Armory Park, as well as the potential impacts associated with the currently proposed renovation on the existing site.

 

In response to this feedback and at the direction of the administration, the district's consultant team developed an alternative new construction and renovation option on the existing middle school site, intended to address many of the concerns raised throughout this process.

 

This alternative concept would create a functionally "like new" middle school on the existing site. This building would be 144,000 square feet total, including nearly 70% new construction.

 

The plan would preserve and renovate the oldest, original portion of the 108-year-old middle school, balancing modernization with preservation.

The proposed scope includes approximately 98,000 square feet of new construction, 46,000 square feet of extensive renovation, and the demolition of approximately 81,000 square feet of the existing facility. Upon completion, the project would result in a modernized middle school totaling approximately 144,000 square feet.
