Five issues relating to Safety have been identified as
part of this JLUS.
SA-1 Future weapons surface danger zones may extend past the
current boundaries of Florence Military Reservation.
SA-2 AZARNG movement between east and west side of Florence
Military Reservation is unsafe.
SA-3 Unexploded ordnance may exist outside the Florence Military
Reservation Impact Area.
SA-4 Vehicle crashes have occurred at the intersection of Arizona
Farms Road and State Route 79.
SA-5 Pinal Airpark’s Runway Protection Zone extends over a portion of
Silverbell Army Heliport.
Key Terms
Runway Protection Zone. Runway protection zones are established by the Federal
Aviation Administration for civilian airports. They are trapezoidal areas starting at the
end of a runway and that serve to enhance the protection of people and property on the
ground in the event an aircraft lands or crashes beyond the runway end by managing the
type of land use within them. Runway Protection Zones underlie a portion of the
approach closest to the airport.
Surface Danger Zone. A surface danger zone (SDZ) is an area around a weapons firing
range from which the access of all military personnel and civilians is restricted due to the
inherent dangers associated with the firing of live munitions. An SDZ can include the
surface (and subsurface) of land and water, as well as the air space overhead through
which projectiles are launched. An SDZ includes the weapons firing position, the target
impact area, and a secondary buffer area, which is an additional distance where errant
projectile / munitions fragments may land without risking harm to life or property.
Surface danger zones vary in size and shape depending on the type of weapon(s) fired,
their firing location, and the projectile trajectory.
