A new school is projected to have a useful life of 50 years. Sanborn Elementary and South Elementary were partially renovated in 1995 and are in substantially good condition. High Plain Elementary was constructed in 2003 and Bancroft in 2014. If approved, the new West Elementary will be the last elementary school to be built in Andover for the foreseeable future. Therefore, it is critical that this proposed facility address the enrollment needs that will emerge over the coming decades.
