The groundbreaking ceremony for the new Wilmington High School has been scheduled for noon on Thursday, April 25. The event will begin with a ceremony on the Town Common, then move to the construction site on Church Street for the official groundbreaking. Voters in December 2011 approved the project by a ratio of 3 to 1, with 3,778 voters favoring a debt exclusion, or temporary property tax increase, for the $81.6 million project. Despite the groundswell of support, the project was not without its critics. Numerous delays and appeals forced officials to push the project back a year. Members of the Wilmington state legislative delegation are expected to join local officials and school leaders at the groundbreaking. The public is welcome. Representatives from the Massachusetts School Building Authority also are expected to be on hand. The building authority is a partner in the project and is expected to reimburse the town $38 million, or roughly 46 percent of eligible costs. The new facility will replace the current Wilmington High School, which was built in 1950.
