The Green Hills Regional Planning Commission was formed in 1967 by Executive Order of Governor Warren E. Hearnes. This followed the passage by the Missouri General Assembly of the “State/ Community Regional Development Act of 1966”. Governor Hearnes came to Trenton, MO in March 1967 and signed the Executive Order creating the Green Hills Regional Planning Commission at a meeting held at the Trenton High School. The Regional Planning Commission was a nine-county organization from 1967 until 1992, when Chariton and Carroll Counties, MO, were added by Executive Order. The Green Hills Regional Planning Commission is formed pursuant to Revised Statutes of Missouri Chapter 251. The Regional Planning Commission is a special purpose political subdivision and has limited powers to engage in planning and comprehensive economic development for the Region.
