18.80.010 Purpose.
The purpose of the RAC zone is to recognize and provide for private aviation and aviation housing uses within the community. This unique zone also provides for the protection of poor, but delicate soils, plants, and natural animal habitat by maximizing open spaces, restricting fencing, and limiting on-site activities. The goal of this zone is to minimize the alteration of the natural landscape while permitting aviation-related uses, protecting the local ecology, and enhancing the local economy. Thus, this zone recognizes the existing character of the land while providing for specific low impact aviation activities and related uses that are best located outside of urban areas.
In the RAC zone, the following regulations shall apply. (Ord. 159 Amd. 1 § 1(Exh. A), 2007; Ord. 159 § 1(Exh. A), 2005)
18.80.020 Uses permitted outright.
In the RAC zone, the following uses and their accessory uses are permitted outright:
(1) Planned unit development for a minimum of five dwelling units and a maximum of 32 single-family dwellings, associated aviation hangars, airstrip, accessory uses appurtenant to permitted uses, excluding permanent mobile homes on an individual lot in compliance with CCC 18.132.010.
(2) Development of single-family dwellings on the existing five tax lots.
(3) Subdivision or land partitioning in conjunction with planned unit development for rural aviation residential purposes, excluding a mobile home subdivision.
(4) New residential single-family homes when part of an approved planned unit development.
(5) New aircraft hangars and aviation-related facilities.
(6) Existing aviation service, repair, and limited aircraft manufacture.
(7) Utility facilities necessary to serve the planned unit development including energy facilities, fire protection methods and ponds, reservoirs and related devices, airstrip repair, paving and enhancements, water supply and treatment, and individual septic systems for each dwelling (community sewage treatment facilities shall not be permitted).

(9) Lot line adjustments.
(10) Removal of human-made debris and demolition of structures.
