The proposal is to shift Runway 3R/21L to the northeast by approximately 1,000 linear feet. This would relocate (shift) runway 3R/21L further east from highway SR89. The proposed shift would relocate the existing departure end of the runway (DER) by 780 linear feet. In turn this shift will enable commercial service operators to clear the One Engine Inoperable (OEI) splay without the current obstructions. The proposed shift would also allow aircraft to fly over the Deep Well Ranch and Pinon Oaks subdivisions at a higher altitude, providing safer operations and to help mitigate noise in these areas by potentially offering quieter operations.
