Tree City U.S.A. began as a 1976 Bicentennial project co-sponsored by the National Association of State Foresters and the USDA Forest Service. The National league of Cities and the U.S. Conference of Mayors are now co-sponsors as well.
To become a Tree City U.S.A., a community must meet four standards:
Establish a tree board or department
Maintain a community tree care ordinance
Create a comprehensive community forestry program with an annual budget of at least $2 per capita
Participate in Arbor Day observance and proclamation
Communities must reapply for certification annually. Indianola is proud to have been awarded the Tree City U.S.A. designation each year since 1994.
