SALINA, Kan. - The future of the Salina-Saline County Health Department is unclear after its building was closed because of concerns its roof might collapse. Salina city commissioners voted Monday to approve a contract that will temporarily move the department to two buildings owned by Salina Regional Health Center. Salina building officials closed the building Thursday after inspectors said its roof was in danger of collapsing. The Salina Journal reports (http://bit.ly/Ka5sMf ) the building is about 95 years old. The health department has used it since 1994. The county owns the building and the city maintains it. After the structure was closed, the city's search and rescue team and some rural fire departments spent three days building 10 support structures to reinforce it.
