§ 11-10D-3 AIRFIELD ENVIRONS SUBDISTRICTS.

   Within the Airfield Environs Overlay District, there are areas affected similarly by the combined characteristics of noise, flight tracks, altitude and accident potential. These areas are designated as Clear Zones (CZs), Accident Potential Zones (APZs) and Noise Zones (NZs). These areas are consistent with Air Force and local community land use guidelines. These areas are subdistricts within the Overlay District.

(Prior Code, § 11-10D-3) (Ord. 04-01, passed 1-6-2004)

§ 11-10D-4 CLEAR ZONE (CZ).

   This subdistrict is the most severely impacted by the operations of the adjacent airfield, which possesses a significant risk factor for aircraft accidents. The placement of structures is not compatible and is therefore prohibited. CZ also encompasses portions of Noise Zones Ldn 75<80 and 80+. Therefore, noise sensitive uses are not compatible without the incorporation of extensive noise attenuation construction techniques. Exposure to outside noise could be a health hazard to persons and animals. It is intended that the principal use of land shall remain for agriculture production of crops and other miscellaneous agriculture services. Residential uses are not permitted, unless otherwise specified in table 1, § 11-10D-13.

   (A)   District use regulations.

      (1)   Uses permitted. Property in CZ shall be utilized only for those uses permitted in the underlying zoning districts, unless otherwise specified in table 1, § 11-10D-13 .

      (2)   Uses permitted by review. Property in CZ shall be utilized only for those uses permitted by review in the underlying zoning districts, unless otherwise specified in table 1, § 11-10D-13 .

   (B)   Site development standards.

      (1)   Standards of underlying district. Property shall be developed in accordance with the development standards of the underlying district.

      (2)   Height. Buildings and structures are prohibited, unless otherwise specified in table 1, § 11-10D-13 . No building or structure shall exceed 25 feet in height or the maximum height specified by the airspace control surfaces plan, whichever is less.

(Prior Code, § 11-10D-4) (Ord. 04-01, passed 1-6-2004)

§ 11-10D-5 ACCIDENT POTENTIAL ZONE (APZ) I.

   This subdistrict is severely impacted by the operations of the nearby airfield. Due to the number of flight tracks over this subdistrict, a risk factor for aircraft accidents does exist, although not as great as CZ. APZ I encompasses portions of Noise Zones Ldn 65<70, 70<75, 75<80 and 80+. Therefore, noise sensitive uses are not compatible without the incorporation of extensive noise attenuation construction. Exposure to outdoor noise could be a health hazard to persons and animals. It is intended that the primary use of land in this district remain for agriculture production of crops and other agriculture services. Residential uses are not compatible with United States Air Force (USAF) recommendations and are not permitted, unless otherwise specified in table 1, § 11-10D-13.

   (A)   District use regulations.

      (1)   Uses permitted. Property and buildings in APZ I shall be utilized only for those uses permitted in the underlying zoning districts, unless otherwise specified in table 1, § 11-10D-13 .

      (2)   Uses permitted by review. Property and buildings in APZ I shall be utilized only for those uses permitted by review in the underlying zoning districts, unless otherwise specified in table 1, § 11-10D-13 .

   (B)   Site development standards.

      (1)   Standards of underlying district. Property shall be developed in accordance with the development standards of the underlying district.

      (2)   Height. No building or structure shall exceed 35 feet in height or the maximum height specified by the airspace control surfaces plan, whichever is less.

(Prior Code, § 11-10D-5) (Ord. 04-01, passed 1-6-2004)

§ 11-10D-6 ACCIDENT POTENTIAL ZONE (APZ) II.

   This subdistrict is heavily impacted by the operations of the nearby airfield, which possess a significant risk factor for aircraft accidents. Residential uses, other than low density single-family dwellings, are not compatible. Density in this area is restricted to one dwelling unit per acre, and commercial areas are limited to 50 persons per acre. APZ II encompasses portions of Noise Zones Ldn 65<70 and 70<75. Therefore, noise sensitive uses are not compatible without the incorporation of noise attenuation construction. Most outdoor uses are only marginally compatible. It is intended that the principal use of undeveloped lands within the district remain for agriculture production of crops and other miscellaneous agriculture services until such time as development is warranted. This subdistrict is also intended to accommodate the wholesale, light industrial and retail uses that are permitted in the underlying zoning districts, which do not concentrate large numbers of people.

   (A)   District use regulations.

      (1)   Uses permitted. Property and buildings in APZ II shall be utilized only for those uses permitted in the underlying zoning districts, unless otherwise specified in table 1, § 11-10D-13 .

      (2)   Uses permitted by review. Property and buildings in APZ II shall be utilized only for those uses permitted by review in the underlying zoning districts, unless otherwise specified in table 1, § 11-10D-13 .

   (B)   Site development standards.

      (1)   Standards of underlying district. Property shall be developed in accordance with the development standards of the underlying zoning district.

      (2)   Height. No building or structure shall exceed the height specified in the underlying zoning district, or the maximum height specified by the airspace control surfaces plan, whichever is less.

(Prior Code, § 11-10D-7) (Ord. 04-01, passed 1-6-2004)

§ 11-10D-7 NOISE ZONE (NZ) 65<70 dB.

   This subdistrict is moderately impacted by the operations of the nearby airfield. Noise sensitive uses are not compatible in the NZ 65<70 dB without the incorporation of noise attenuation construction techniques. NZ 65<70 dB also encompasses portions of APZ I and APZ II. The district is primarily developed as low density single-family residential subdivisions and a community park, with open space and farmland located near the base. Most outdoor uses would be compatible. It is intended that the uses permitted in the underlying zoning districts shall be permitted in Noise Zone 65<70 dB with noise attenuation required for noise sensitive uses.

   (A)   District use regulations.

      (1)   Uses permitted. Property and buildings in NZ 65<70 dB shall be utilized only for those uses permitted in the underlying zoning districts, unless otherwise specified in table 1, § 11-10D-13 .

      (2)   Uses permitted by review. Property and buildings in NZ 65<70 dB shall be utilized only for those uses permitted by review in the underlying zoning districts, unless otherwise specified in table 1, § 11-10D-13 .

   (B)   Site development standards.

      (1)   Standards of underlying district. Property shall be developed in accordance with the development standards of the underlying zoning district.

      (2)   Height. No building or structure shall exceed the height specified in the underlying zoning district, or the maximum height specified by the airspace control surface plan, whichever is less.
