§ 4. Airport noise zones and boundaries.

(a)

The boundaries of the airport noise zones shall be as shown on the zoning map as adopted and amended by city council.

(b)

For purposes of administering and enforcing the provisions of this ordinance, there shall be four (4) airport noise zones and three (3) aircraft accident potential zones:

Airport noise zones shall be as follows:

(1)

Noise Zone less than 65 dB DNL;

(2)

Noise Zone 65-70 dB DNL;

(3)

Noise Zone 70-75 dB DNL;

(4)

Noise Zone greater than 75 dB DNL;

Aircraft accident potential zones shall be as follows:

(1)

CZ - Clear Zone (an area extending outward from the threshold of an active runway which possesses a high potential for accidents);

(2)

APZ-I - Aircraft Accident Potential Zone I (an area extending outward from a clear zone which posses a significant potential for accidents); and

(3)

APZ-II - Aircraft Accident Potential Zone II (an area extending outward from either a clear zone or aircraft accident potential zone I which possesses a measurable potential for an accident.

The purpose of the establishment of four (4) airport noise zones and three (3) aircraft accident potential zones is to distinguish between the severity of the level of noise impacts so that appropriate acoustical performance standards can be employed to mitigate the adverse impacts of aircraft noise and to facilitate accurate identification of such zones. Each of the four (4) airport noise zones and three (3) aircraft accident potential zones shall be designated on the zoning map as adopted and amended by city council.
