PLAN AREA The 2009 Airport Master Plan shows areas of airport impact and the anticipated Day-Night Sound Level (DNL) zones resulting from airport activities (Fig 1).Using current FAA guidelines, six separate impact zones have been identified and will be used to restrict land use according to criteria outlined in the 2009 Airport Master Plan and in the Land Development Code. DNL sound level contours shall be used to determine noise attenuation levels in and around the airport. Habitable buildings within the 6 Airport Impact Zones shall be constructed using noise attenuation techniques to limit noise within each structure. Interior noise must be attenuated per the Airport Noise Overlay Soundproofing guidelines of LDC 5.2.7. It is recommended that habitable buildings outside of the 6 Airport Impact Zones but falling within the Airport Influence Area also be constructed using noise attenuation techniques to limit noise within each structure. Building height for all structures shall coincide with and be constrained by Part 77 of the FAA regulations. To help document the proven concerns for encroachment of inappropriate land uses around the airport, the airport manager has prepared a white paper detailing airport and aircraft operations (Appendix B). This research describes local aircraft practices and selected case studies that highlight the need for limiting residential densities near the airport and for creating an Airport Influence Area and avigation easement requirement. GRANITE DELLS COMMUNITY PLAN This 1991 community plan covers the SE quadrant of ASAP, and lands south of ASAP. It was written by Yavapai County staff with the direct input of many Granite Dells residents, the plan calls for low intensity uses that maintain the rural character. Most of the land use designations are compatible with nearby airport activity — light commercial, low and very low density residential, and recreational (Appendix C). However, the Agricultural classification assigned to lands east of the abandoned railroad line (now the Peavine Trail) is a holding designation that anticipates future changes. This "Agricultural" designation may be the most significant area to plan for given the new arterials anticipated to cross Granite Dells Ranch and Point of Rocks Ranch. The community plan also states that sound reverberation occurs as planes pass over the Granite Dells, and recommends that aircraft should therefore be routed around the Dells. This fact highlights the incompatibility concerns from housing located in relatively close proximity to the airport. 2
