The MCAs are used to define the geographic areas where the JLUS strategies are to be applied . This technique ensures the strategies are applied to the appropriate areas , and that locations deemed not subject to a specific compatibility issue are not adversely impacted by regulations inappropriate for their location or circumstance .
These MCAs are shown on Figures 14 through 17 and are discussed in the following sections .
Noise Military Compatibility Area ( Figure 14 ) Noise is often a concern to the public surrounding military installations with flying missions . The Noise MCA includes all land located off‐installation within the Keesler AFB 65 decibels ( dB ) day‐night sound level ( DNL ) noise contour associated with military aircraft activities . Residential developments and other noise‐sensitive land uses within this MCA may be subject to sound attenuation measures to reduce interior noise impacts .
Noise level reduction requirements in planning documents are key to ensuring noise sensitive uses such as residential , visitor accommodation , healthcare facilities , education facilities and government facilities are compatible in areas that experience noise levels of 65 dB DNL or greater . Local building codes can also be used to ensure that noise‐attenuation measures are incorporated in all new development within the Noise MCA .
Safety Military Compatibility Area ( Figure 15 ) The proposed Safety MCA addresses compatible land use types and densities / intensities within the Clear Zones ( CZs ) and Accident Potential Zones ( APZs ) I and II of Keesler AFB ’ s runway . Each of these is a subzone of the Safety MCA . The current location of each safety subzone is based on the airfield layout and air operations identified in Keesler AFB ’ s AICUZ Report . The boundaries of each subzone should be updated based on any operational changes that occur with each AICUZ Study update .
The Safety MCA is intended to prevent the deve uses in areas with the greatest potential for an a zones were identified as a result of the Air Force safety zones as areas where an aircraft accident occur ( in the unlikely event that one was to occu departure , arrival , and pattern flight tracks and a historical data .
Within the CZ , most types of land use are incom operations and no development is recommende preclude land uses that concentrate large numb residential uses including multifamily dwellings , facilities , places of worship , educational facilities recreational facilities ) within the APZs . While the unlikely , the Air Force recommends low density the APZs to ensure the maximum protection of p
Single family residential uses are considered com maximum density of two units per acre only in A compatible uses within APZ II include agriculture retail , and light industrial .
The following table summarizes the compatible guidance in Air Force Instruction 32‐7063 . A com land uses and compatibility criteria can be found the JLUS Background Report .
