The Stoneleigh Elementary School community is already looking forward to Wednesday, June 6 — their last day of school before summer vacation.

But when class is dismissed for the last time that day, the faculty, staff, students, and their families will have already done their fair share of celebrating.

County Councilman David Marks, who represents Towson, said Thursday that the groundbreaking for the 200-seat addition and systemic renovation to Stoneleigh Elementary will be held at 10 a.m. that day, marking the official beginning of a project that has been years in the making.

"It's a very exciting event, and we've worked very hard for this," Marks said.

While the renovation and addition are being completed, Stoneleigh and its students, faculty, and staff will move uptown to the old Carver Center for Arts and Technology for the upcoming school year.

Stoneleigh is getting out two days earlier than the rest of the county to allow for more moving time.

Construction is expected to take 15 months, and could be completed in time for Stoneleigh students to return for th 2013-2014 school year.
