Pinal County JLUS Background Report | Page 242

  by ADOT and the Federal Highway Administration for public review and comment from  April 5, 2019 to July 8, 2019.  The preferred alternative identifies a portion of the corridor  less than two miles west of Silverbell Army Heliport.  In conjunction with future planned  growth around Silverbell Army Heliport (see Issue LU‐3), the I‐11 corridor could promote  growth that could impact the missions at Silverbell Army Heliport.  Although it is not yet  funded and years away from implementation, it will be important to coordinate  transportation and land use planning with a future I‐11 corridor that may promote  incompatible growth around Silverbell Army Heliport.    5.8 Land / Airspace Competition (LAS) The military manages and uses land and air space to accomplish testing, training, and  operational missions. These resources must be available and of a sufficient size,  cohesiveness, and quality to accommodate effective training and testing.  Military and  civilian land and air operations can compete for limited land and air space, especially  when the usage areas are in close proximity to each other. Use of these shared resources  can impact future development and operations for all users.      Seven issues relating to Land / Airspace Competition have been identified as part of this JLUS. LAS-1 There may be Increased use of unmanned aerial systems in the future. LAS-2 Helicopter flight areas are not protected. LAS-3 There is limited space at Florence Military Reservation. LAS-4 Restricted airspace over Florence Military Reservation should be preserved. LAS-5 Commercial aviation activities are not coordinated with the AZARNG. LAS-6 There are private airstrips in the JLUS Project Area. LAS-7 AZARNG has a need to conduct specific types of helicopter flight and landing operation training throughout Pinal County.   5-50 Compatibility Assessment
