About half of the nearly 850 students at Green T. Lindon Elementary School are being taught in portable buildings grouped together behind the main school building — a situation that’s about to change.

Construction of three new classroom buildings will be complete in early December, and it’s possible students and their teachers could be in the new rooms when they return from Christmas break, facilities director Kyle Bordelon said.

The expansion of the campus has been an overdue need for the crowded school that was initially constructed for about 400 students. The $9 million-plus project also includes a new administrative building and multipurpose building to be used as a gym and public gathering space, as well as a second phase of projects.

A cafeteria will be expanded in the second slate of projects, and another classroom building with eight rooms will be constructed once the portables are moved off the campus.

About 500 students in grades second through fourth are in portable buildings and will move into the new buildings, Lindon Principal Kay Victorian said.

The new classroom space enables the school to create grade level “pods” that will foster greater collaboration among teachers, Victorian said.

“Now, they’re self-contained in the portables,” she said. “The pods are better for teacher planning and collaboration, and we’ll be able to allow teachers to team teach.”

With the new construction, students’ greenspace for play is limited on the campus, and the school has been using a neighboring ball park. Bordelon said he’s in talks to secure 4.1 acres behind the school to provide additional greenspace.

“We’ve run out of property here, so I’ve been working with the owners,” Bordelon said.

At least $175,000 was set aside in the 2014-15 capital projects budget for the purchase of additional property for the school.

Both projects are part of a $30 million bond sale approved by the board in 2012 for school projects, including a more than $5 million expansion at Youngsville Middle School where students are now in a new, 11-classroom wing. Work on construction of a second classroom building with five to seven additional classrooms will begin, Bordelon said.
