Increase in electronic billboards may impact night training.
As electronic billboards are used with greater frequency in the JLUS project area,
they may negatively impact military night training operations in the future.
There is potential for future impacts to night training at Florence Military
Reservation.
There are currently no existing major impacts to night training at Florence
Military Reservation, but as new construction, infrastructure improvements, and
other types of growth and development continues around the installation,
increased artificial lighting may inhibit night vision goggle training.
Future growth may impact night training at Silverbell Army Heliport and
Picacho Peak Stagefield.
Night training occurs in the region around Silverbell Army Heliport and
Picacho Peak Stagefield. Future growth around the installation and operational
areas, especially near approach and departure routes, could impact night vision
training capabilities.
Noise
Sound that reaches unwanted levels is referred to as noise. The central issue with noise
is the impact, or perceived impact, on people, animals (wild and domestic), and general
land use compatibility with noise‐sensitive uses such as residential, schools, and
hospitals. Exposure to high noise levels can have a significant impact on human activity,
health, and safety. The decibel (dB) scale is used to quantify sound intensity. To help
understand the relevance of decibels, a normal conversation often occurs at 60 dB, while
an ambulance siren from 100 feet away is about 100 dB. Noise associated with military
operations (overflight of military aircraft, firing of weapons, etc.) may create noises in
higher dB ranges. Three issues relating to Noise have been identified as part of this JLUS.
Noise from helicopter operations may cause impacts.
Helicopter operations, including training activities and the movement of aircraft
from one site to another, occur in much of the JLUS Project Area. Low‐level
flights generate the greatest potential concern for noise impacts. Future land
development near helicopter training areas and flight corridors may increase
noise impacts and complaints.
Noise complaints are sometimes received related to non‐AZARNG aircraft.
Some noise complaints have been received by the AZARNG regarding aircraft
that are not associated with AZARNG missions. This includes complaints
regarding noise from Phoenix‐Mesa Gateway Airport and from transient aircraft
operating throughout the Project Area (including military aircraft not associated
with AZARNG).
