“Reserve lot” means a large lot reserved in a plat or short plat for future development. The large lot is intended to be reserved for intensive development at some future date when utilities become available. The large lot may have a community drainfield system on it that serves other smaller clustered lots within the plat or short plat until such time as sewer becomes available to the area and may also be used for open space purposes until such time as it is developed. (Ord. 1024 §20, 1995).
