The Colony of Olivenhain Town Council was incorporated in 1967. All residents and property owners of Olivenhain are welcome to join the Olivenhain Town Council as voting members. The annual membership fee of $25 per family pays for the newsletters and helps support maintenance of the property and grounds.
General Meetings are held on the first Wednesday of most months at the Olivenhain Meeting Hall at 7:00 p.m. Many meetings feature a guest speaker on a topic of interest to residents. Members of the Board of Directors are elected at the General Meeting in June each year.
