Ames School District officials are giving the public one more chance to tour the high school as debate continues about what to do with the building. The tour is part of an effort to get the public's input about future construction plans for the high school. School board members have individually supported the concept of building a new high school, which could cost as much as $95 million. Ames voters would be asked to support a bond issue for the project, with an election possibly coming next April. The other option is an expansion and renovation of the current building. While it would be cheaper up-front, district officials says it carries higher operational costs than a new building. More than 160 people took part in three previous tours of the high school.
