Fewer portable classrooms in Columbus (Ohio) district

From The Columbus Dispatch: The Columbus (Ohio) district has reduced its use of portable classrooms, but eliminating all of them is years away. For last school year and the next one, the district will have 56 portables at 31 buildings; that's about half of what it had six years ago. The long-term plan is to move away from using the modular classrooms entirely, but the district doesn't know what will happen
