Land use guidelines for <strong>Air</strong> <strong>Force</strong> <strong>AICUZ</strong> outlined in <strong>Air</strong> <strong>Force</strong><br />

Handbook (<strong>AF</strong>H) 32-7084 <strong>AICUZ</strong> Program Manager’s Guide<br />

reflect preferred land use recommendations for areas underlying<br />

clear zones (CZs), accident potential zones (APZs) I and II, as well<br />

as for four predicted noise exposure zones (a description of these<br />

areas can be found in Chapter 3):<br />

<br />

<br />

<br />

<br />

65-70 A-weighted decibel (dB[A]) day-night average sound<br />

level (DNL);<br />

70-75 dB(A) DNL;<br />

75-80 dB(A) DNL; and<br />

80+ dB(A) DNL.<br />

The predicted noise exposure zones are delineated by connecting<br />

points of equal noise exposure (contours). Land use<br />

recommendations for these noise exposure zones have been<br />

established on the basis of sociological studies prepared and<br />

sponsored by several federal agencies, including the U.S.<br />

Department of Housing and Urban Development (HUD), the U.S.<br />

Environmental Protection Agency (EPA), the U.S. Department of<br />

Transportation (DoT), and the <strong>Air</strong> <strong>Force</strong>, as well as state and local<br />

agencies. The guidelines recommend land uses that are compatible<br />

with airfield operations while allowing maximum beneficial use of<br />

adjacent properties. Additionally, guidelines for maximum height<br />

of man-made structures are provided to protect the navigable<br />

airspace around an airfield, particularly the approach/departure<br />

corridors extending along the axis of the runways. The <strong>Air</strong> <strong>Force</strong><br />

has no desire to recommend land use regulations that would render<br />

property economically useless. The <strong>Air</strong> <strong>Force</strong> does, however, have<br />

an obligation to the inhabitants of the <strong>Plant</strong> <strong>42</strong> environs and to the<br />

citizens of the United States to point out ways to protect the people<br />

in adjacent areas as well as the public investment in the installation<br />

itself.<br />

The <strong>AICUZ</strong> program uses the latest technology to define noise<br />

levels in areas near <strong>Air</strong> <strong>Force</strong> installations. An analysis of <strong>Plant</strong><br />

<strong>42</strong>'s existing and anticipated flying operations was performed,<br />

including types of aircraft, flight patterns, variations in altitude,<br />

power settings, number of operations, and hours of operations. This<br />

information was used to develop the noise contours contained in<br />

this study. The DoD NOISEMAP modeling software and the<br />

previously mentioned DNL metrics were used to define the noise<br />

exposure zones at <strong>Plant</strong> <strong>42</strong>. In addition and in recognition of<br />

California’s use of a similar but alternative noise metric,<br />
