Sec. 1005. ACOZ - Aviation Land Use Compatibility Overlay Zone: — Kings County Zoning Code

A. Purpose: The regulations contained in the Aviation Land Use Overlay Zone (ACOZ) are intended to be applied to areas where additional controls to supplement or to modify those of the base zoning district are required.
1. The specific purposes of the ACOZ are to:
  - a. Reduce potential conflicts around the Hanford airport concerning noise and safety due to the operation of private aircraft.
  - b. Encourage proper land use planning to ensure that agriculture, aircraft, and residential uses co-exist to maintain economic sustainability while providing residents a strong quality of life.
  - c. Implement the policies and provisions of the 2035 Kings County General Plan .
2. The ACOZ shall be shown on the Zoning Map by adding the designator "AC" to the base district designation. The ACOZ will be applied to within the airport compatibility areas around the Hanford Airport.
3. The provisions of this chapter shall apply to all parcels of land located within the designated boundaries of the overlay zone as illustrated on maps contained on the Official County zoning map.

DEVELOPMENT CODE

B. Development Standards and Regulations
1. New residential development is prohibited when proposed within the 70 Community Noise Equivalent Level (CNEL) or greater noise contours for any military airfield, airport or helipad within Kings County.
2. The Kings County Airport Land Use Compatibility Plan (ALUC) and the 2035 Kings County General Plan address land use compatibility surrounding the Hanford Airport. Use of the procedures and criteria contained within the Kings County ALUC serves to ensure that the risks to public safety related to aircraft flight operations around airports is minimized.
3. The ACOZ for the Hanford Airport designate the following specific areas of potential impacts associated with airport operations:
  - a. A – Runway Protection Zone or Within Building Restriction Line
  - b. B1 – Approach/Departure Zone and Adjacent to Runway
  - c. B2 – Extended Approach/Departure Zone
  - d. C – Common Traffic Pattern
  - e. D – Other Airport Environs
4. Land use and development within the overlay zones of the Hanford Airport shall be consistent with the Airport Land Use Compatibility and Land Development Restrictions contained in the following Tables:

Table 10-2 Aircraft Land Use Primary Compatibility Notes

Residential development should not contain more than the indicated number of dwelling units per gross acre.
1 Clustering of units is encouraged as a means of meeting the Required Open Land requirements. The land use should not attract more than the indicated number of people per acre at any time. This figure should
2 include all individuals who may be on the property (e.g. employees, customers/visitors, etc.) These densities are intended as general planning guidelines to aid in determining the acceptability of proposed land uses. Open land requirements are intended to be applied with respect to an entire zone. This is typically accomplished as
3 part of a community General Plan or a specific plan. See supporting compatibility policies in the General Plan on safety for definition of open land.

6	Hazards to flight include physical, visual, and electronic forms if interference with the safety of aircraft operations. See supportingcompatibility policies in the General Plan on airspaceprotection for details.
7	Storage of aviation fuel, other aviation-related flammable materials, and up to 2,000 gallons of non aviation flammable materials is exempted from this criterion in Zones B1 and B2.
