The Regional Planning Commission is composed of one member from each of the three boards of county commissioners and the county engineers of each county. In addition, six county "members-at-large" are appointed by the boards of county commissioners--two from each county. Also, nine "citizen members-at-large" are appointed by the boards of county commissioners--three from each county.

Municipalities of city status have two representatives and an alternate. Participating villages have one representative and an alternate. Participating townships have one representative.

Currently, there are three counties, two cities, nineteen of the twenty-one incorporated villages and all forty-three townships listed as members of the commission.

The Executive Committee is presently comprised of the president, first and second vice-presidents, secretary, treasurer and fourteen other people who were elected from the entire membership at the annual meeting. In addition, the city and county engineers of each city and county are members of the Executive Committee—all with voting privileges. Ex-officio members, without voting privileges include the District Deputy Directors of the Ohio Department of Transportation’s Districts Six and Seven and any chairman of a Study Committee who is not an elected member of the Executive Committee.

The Executive Committee is the policy and decision making body, but their actions are always subject to review by the entire commission at any annual or special meeting.

The Executive Committee meets the second Thursday of each month at 1:15 P.M. in the Commission's office in East Liberty. Representatives from any of the member municipalities or townships are always welcome to attend any or all meetings and participate in any discussion. They are, however, not permitted to vote as a member of the Executive Committee unless they are a duly elected member thereof. Minutes of all Executive Committee meetings are mailed to each member; also, a notation indicating the date of the next scheduled meeting.

The annual meeting of the entire membership is held the third Thursday night in November. For the past several years it has been held at the Ohio Hi-Point Joint Vocational School and consists of a dinner prior to the business portion of the meeting. All representatives are encouraged to attend this meeting and participate in any discussion and vote on any issue.
