Monday night district residents were invited to comment on the ten year facility plan being put together by the school board and a citizens committee.
Director of Operations Curt Pratt says Bettendorf Middle School was built in 1962, and needs some major work.
"The classrooms are small, the infrastructure has aged, and a lot of it is reaching the end of its life - the roof, the mechanical systems, some of that stuff - and it's not really feasible to renovate the building the way it was constructed."
Possible projects for the high school include classrooms for new programs, such as health science, building trades and related programs, fine arts, and more space for athletics.
The estimated cost is 70 million dollars.
Pratt says the school board will hold a workshop on the long range plan next week, and could make some decisions soon after that.
