A groundbreaking ceremony was held Thursday for a new administration building for ISU Extension’s 4-H youth program. 4-H Youth Programs director Joe Kurth says the new facility on Iowa State’s campus will allow the state 4-H staff to move out of Curtis Hall.The group has shared space with Iowa State in Curtis Hall since the 1960s, and has outgrown that space. Kurth says the new Extension and 4-H Youth Development Building will be home for state 4-H and foundation staff members, ISU Extension’s communications staff, and an exhibit hall.Kurth says the move to a new building comes at a key time for 4-H as they’re celebrating their centennial this year. One in four Iowa youth are involved in the 4-H youth program.
