Sec. 656.1004. - Definitions.

For the purposes of this Part: (a) Accident Potential Zone I (APZ I) applies only to military airfields. This is defined as the area 500 feet either side of the runway centerline and 2500 feet from the end of the Clear Zone for Class A runways. For Class B runways it is 3000 feet wide beginning at the end of the clear zone and 5000 feet long. The APZ may be curved and enlarged to conform to the shape of the predominate flight track. (b) Accident Potential Zone II (APZ II) applies only to military airfields. For Class A runways this is defined as the area 1000 feet wide and 2500 feet long beginning at the end of APZ I. Accident Potential Zone II (APZ II) for Class B runways is 3000 feet wide and 7000 feet long beginning at the end of APZ I. The APZ may be curved and enlarged to conform to the shape of the predominate flight track. (c) Air installation compatible use zones (AICUZ) program is a Department of Defense (DoD) program and only applies to military airbases. The purpose of the program is to protect the public's safety, health and welfare while safeguarding the operational capabilities of military airports. The main intent of the AICUZ Program is to insure that development of surrounding lands will be compatible with noise levels and accident potential associated with military airport operations. (d) Airport (Civilian) includes all of the following: (1) Jacksonville International Airport. (2) Craig Airport. (3) Herlong Airport. (4) Cecil Field. (e) Airport (Military) includes all of the following: (1) Naval Air Station, Jacksonville, Florida. (2) Outlying Field Whitehouse, Jacksonville, Florida. (3) Naval Station Mayport, Jacksonville, Florida. (f) Airport elevation means the highest point of an airport's usable landing area measured in feet above mean sea level. (g) Airport environ zone (civilian airports) means those areas which are included in a height and hazard zone; noise zone; notice zone, school regulation zone, miscellaneous use zone, runway safety area, and runway protection zone. These zones are determined by the Jacksonville Aviation Authority. If consistent with the Comprehensive Plan, maps associated with zones may be added to the Zoning Atlas in the form of an Airport Environ Zone map and the requirements of Part 10 enforced within them by action of the City Council, after recommendation by the Planning and Development Department and the Planning Commission. (h) Airport environ zone (military airports) means those areas which are included in an height and hazard zone; noise zone, notice zone, school regulation zone, accident potential zone and/or clear zone, miscellaneous use zone, and the lighting regulation zone at Outlying Field Whitehouse. These zones are determined by the Navy. If consistent with the Comprehensive Plan, maps associated with zones may be added to the Zoning Atlas in the form of an Airport Environ Zone map and the requirements of Part 10 enforced within them by action of the City Council, after recommendation by the Planning and Development Department and the Planning Commission. (i) Airport Notice Zones are those zones requiring execution of an Airport Notice Zone Acknowledgement, as required in Section 656.1010 . All parcels partially or completely within the Notice Zone shall be denoted with the suffix of P10. The Airport Notice zones are areas for which the limits are represented by the 60 DNL to 64.99 DNL noise contour range. This zone is determined by the Navy and Jacksonville Aviation Authority. Maps associated with the Airport Notice Zone may be added to the Zoning Atlas and the requirements of Part 10 enforced within it only by action of the City Council, after recommendation by the Planning and Development Department and the Planning Commission. For military airports only, the Airport Notice Zone also shall encompass all lands within accident potential zones, lighting regulation zone (for OLF Whitehouse only) or the 150-foot Height and Hazard Zone which is also known as inner horizontal and conical surface zone as shown on the Airport Notice Zone Map and as adopted into the Zoning Atlas (only as it applies to NASJax, NSMayport and OLF Whitehouse). (j) Airport Notice Zone Acknowledgement is a notice filed pursuant to 656.1005 , subsections A and B, and 656.1010 . The Acknowledgement form is found at 656.1014 . (k) Airport obstruction is defined as a structure or object of natural growth or use of land which would exceed the federal obstruction standards as contained in Title 14, Code of Federal Regulations (CFR), Part 77 or NAVFAC P-80.3 01/82 which obstructs the airspace required for flight of aircraft in landing and takeoff at an airport or which is otherwise hazardous to the landing or taking off of aircraft. Examples include an object constructed, controlled, or installed by man, including but not limited to buildings, antennae, towers, smokestacks, utility poles, cranes, trees, vegetative plants and overhead transmission lines. (l) Clear Zone (military airports) is the trapezoidal government owned area abutting the end of each airport runway. The limits of the clear zones vary based on the type of runway and within the clear zone land should be cleared and graded and free of above ground objects except for U.S. Navy approved structures. (m) Cluster means to group uses close together rather than distributing them evenly throughout a site while remaining below the applicable gross density or intensity ceiling of the land use plan category. (n) Day/Night Noise Level (DNL) is a cumulative measurement of community noise exposure established by the Federal government. The sound exposure levels from aircraft events are accumulated to determine the sound pressure present in a 24-hour period and a 10 decibel penalty is applied to each aircraft event that occurs between 10:00 p.m. and 7:00 a.m. DNL values are typically shown as a series of noise contours surrounding the airport. (o) dB Decibel is the measurement of sound by its pressure or energy level. The decibel scale is logarithmic. Noise energy doubles with each increase of 3 decibels. (p) dBA is the measurement of sound pressure using an A-weighted scale to best represent the range of human hearing. (q) Fully shielded shall mean an outdoor light fixture shielded in such a manner that all light emitted by the fixture, either directly from the lamp or indirectly from the fixture, is projected below a horizontal plane extending from the bottom of the light fixture. (r) Height and Hazard Zone includes lands located within the surface limits of the airport height zone for which there is a potential for such hazards as electronic interference, light glare, bird strike hazard and other potential hazards to safe navigation of aircraft. Height zone means the obstruction height limits as defined in Title 14, Code of Federal Regulations (CFR), Part 77 and Navy NAVFAC P-80.3 set forth in this Part. They include all the land lying beneath the approach, transitional, horizontal and conical surfaces as they apply to a particular airport. The area located in more than one of the described zones is considered to be only in the zone with the more restrictive height limitation. The City has defined 0′, 35′, 50′, 150′, 300′, and 500′ Height and Hazard Zones and structures exceeding these heights must be referred to the Jacksonville Aviation Authority or the US Navy as required by Section 656.1005 . These zones are shown on the Zoning Atlas and included in the Airport Environs Maps. (s) Lighting Regulation Zone means an area that includes all lands beneath the primary zone, clear zone, both approach and departure clearance zones (sloped and horizontal), inner horizontal conical surface zone and transitional zone (see NAVFAC P-80.3) in conjunction with Outlying Field Whitehouse only. (t) Minimum vectoring altitude means the lowest mean sea level altitude at which an aircraft on instrument flight rules will be vectored by a radar controller, except when otherwise authorized for radar approaches, departures and missed approaches. (u) Miscellaneous Use Zone means an area within the Height and Hazard Zone as defined in R above, of airports where JAA or US Navy approval is required for the uses listed in 656.1005 Subsection A (d) and Subsection B (d). (v) Noise Level Reduction (NLR) is a measurement standard for the reduction in sound level transmission between two designated locations for a stated sound frequency band. NLR standards are used to evaluate the effectiveness or establish the requirements of techniques to limit sound level transmission in order to prevent or mitigate adverse noise impacts. (w) Noise Zones are areas for which the boundaries are represented by DNL noise contour ranges. All parcels partially or completely within the Noise Zone shall be denoted with the suffix of P10. The noise zones are Noise Zone A (DNL values 75 and greater); and Noise Zone B (65 DNL to 74.99 DNL range). These zones are determined by the Navy and the Jacksonville Aviation Authority. Maps associated with Noise Zones may be added to the Zoning Atlas and the requirements of Part 10 enforced within them only by action of the City Council, after recommendation by the Planning and Development Department and the Planning Commission. (x) Runway Protection Zone (RPZ) is a trapezoidal area starting 200 feet from the existing or future runway ends at a civilian airport and extending 1,000 to 2,500 feet beyond the starting point depending on the type of aircraft and the approach visibility minimums for the runway that is intended to enhance the protection of people and property on the ground. The Federal Aviation Administration (FAA) requires the clearing of all incompatible objects and activities from this area and encourages the airport to acquire a sufficient property interest in the RPZ to control the land uses on the property to prohibit residences and places of public assembly, churches, schools, hospitals, office buildings, shopping centers and fuel storage facilities. (y) Runway Safety Area is an area surrounding the runways at civilian airports that is prepared or suitable for reducing the risk of damage to airplanes in the event of a problem on landing or take-off by clearing all obstructions from the area. This surface extends 600 to 1,000 feet from the end of an existing or future runway depending on the type of aircraft operating from the runway. (z) School Regulation Zones are areas defined in FS 333.03. School sites are regulated based on their relationship with existing or planned runways shown in the AICUZ, in the case of a military facility or Master Plan, in the case of a civilian facility. School regulation zones are shown on the Zoning Atlas and will be included in the Airport Environs map. (Ord. 2006-1225-E, § 1; Ord. 2008-258-E, § 1)
