In May 2005, voters in Centerville/Washington Township supported a $4.4 million operating levy and a $2.5 million bond issue designed to compensate for a predicted district enrollment increase to 9000 students. Part of this levy includes a new addition to the front. The addition, completed during the summer of 2007, includes 9 new chemistry and physics classrooms and 3 new labs, a new main entrance, additional classroom space, and improved cafeteria commons areas. This addition is now finished and used daily by the students. The new cafeteria areas provide several booths to students and less space for the lunch line area.
