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).

(8) Modifications to a planned unit development with permitted uses.

(9) Lot line adjustments.

(10) Removal of human-made debris and demolition of structures.

(11) Natural areas or open spaces protected by conservation easement or similar instrument. (Ord. 321 § 5, 2020; Ord. 159 Amd. 1 § 1(Exh. A), 2007; Ord. 159 § 1(Exh. A § 1), 2005)

18.80.030 Conditional uses permitted.

In the RAC zone, the following uses and their accessory uses may be permitted subject to the provisions of Chapter 18.160 CCC:

(1) Water features or devices (excluding fire protection ponds).

(2) New home occupations carried on by residents as an accessory use within their dwelling, garage, or other buildings permitted in the zone.

(3) New building and structural lot coverage exceeding a total of two and one-half percent of the planned unit development area.

(4) Building and structural elements exceeding 30 feet in height, excluding architectural features used to break up the mass and bulk of structural facades.

(5) Modifications to planned unit development to allow other conditional uses.

(6) Fire fuel vegetation removal and mitigation. (Ord. 159 Amd. 1 § 1(Exh. A), 2007; Ord. 159 § 1(Exh. A § 2), 2005)

18.80.040 Yard and setback requirements.

In the RAC zone, the following yards and setbacks shall be maintained:

(1) The front yard setback shall be a minimum of 20 feet from a property line fronting on a paved accessway serving the planned unit development.

(2) There shall be a minimum side yard setback of 10 feet for all uses, except in the case of a nonresidential use adjacent to a residential use the minimum side yard shall be 20 feet.

(3) There shall be a minimum rear yard setback of 20 feet for all uses. (Ord. 159 Amd. 1 § 1(Exh. A), 2007; Ord. 159 § 1(Exh. A § 3), 2005)

18.80.050 Dimensional standards.

In the RAC zone, the following dimensional standards shall apply:

(1) Percent of Site Coverage. Any new residence, hangar and accessory structures shall not cover more than two and one-half percent of the planned unit development site unless a conditional use permit has been granted.

(2) Building Height. No residential structure, nor the enlargement of any existing residential structure, shall be hereafter erected to exceed more than 30 feet in height, excluding architectural features used to break up the mass and bulk of the facade. Aircraft hangars shall be limited to heights necessary to support the function of the use.

(3) Residential Structure Design. All residential structures shall be designed to reduce impact upon the natural area. This may be accomplished by use of the following techniques:
