Metal detectors and similar devices are the primary tools used for identifying UXO. They
can detect the presence of dud artillery rounds, but also detect other non‐threatening
metals like shrapnel. Analysis of metal detector signals can increase the probability of
identify UXO, but the only way to know for sure is to dig up the object in question and
analyze.
In a typical cleanup effort, the site will be scanned with metal detectors to map the
locations of buried metal. The data will then be analyzed to identify the metal most likely
to be UXO. The site will be rescanned, and suspicious items will be excavated. These
efforts are both time consuming and costly. In the event that a cleanup is required, the
time to acquire funding for the effort will likely be lengthy as it would have to be planned
and programmed into the DoD budget.
Issue:
SA‐4
AZARNG Site:
Florence
Military
Reservation
Vehicle crashes have occurred at the
intersection of Arizona Farms Road and
State Route 79.
There have been recurring instances of
eastbound traffic on Arizona Farms Road failing to
stop at State Route 79 and crashing through the
fence onto Florence Military Reservation.
Compatibility Assessment
Arizona Farms Road is a two‐lane roadway that runs east‐west in the Town of Florence.
The roadway ends at the intersection with SR 79 near the FMR perimeter fence. There
have been multiple instances in the past where vehicles traveling east on Arizona Farms
Road fail to stop at SR 79 and crash through the installation fencing at FMR. These events
have reportedly occurred at night, during times of low visibility. Additionally, as Arizona
Farms Road approaches SR 79, the roadway inclines which can make it difficult for
motorists to see that the road ends if they are traveling faster than the speed limit, as has
been reported on numerous occasions.
The impact of vehicles with the perimeter fence is both a safety and security issue for
FMR as well as the driver and passengers of the vehicle. The time spent by security forces
monitoring breaches in the fenceline to ensure that they do not become temporary
security vulnerabilities is also a concern.
