WHAT IS A
JOINT LAND USE STUDY?
010918wsa HC BOC Page 3
•A study funded by the DoD’s Office of Economic Adjustment to
help communities and military installations work together in
achieving compatible growth and long-term sustainment of
the military training mission.
WHAT IS A JLUS?
010918wsa HC BOC Page 4
•Identify and mitigate barriers to the long term
sustainability of the installation’s training mission.
•Promote compatibility between civilian land use and
military training / operational impacts.
•Strengthen coordination and communication between
local governments and the installation.
•Raise public awareness and understanding of
compatible growth issues.
JLUS PURPOSE / GOALS

LARGE CALIBER NOISE CONTOURS
CDNL / PK15
010918wsa HC BOC Page 14
OBSERVATIONS
•Large Caliber CDNL Contours:
–CDNLs are weighted annual measurements for low frequency noise
–Day/night operations averaged over 250 days with +10 dB penalty for nighttime firing
–Based on even distribution of ammunition expenditure to all artillery firing points
–Off-post expansion of 57+ dB noise contour in the southeast quadrant vs. historic noise contours
–Some off-post contraction of the 62-70 dB contour along southern boundary vs. historic noise contours
–All 70+ dB contours remain on-post

Noise Source Decibel
Level

Effect to the Unprotected Ear
Jet take-off (at 25m)150 Eardrum rupture
Chainsaw 120 Painful
Live rock music 110 Average human pain threshold
Motorcycle 100 Hearing damage possible after 8 hours of
exposure
Vacuum Cleaner 70 Annoyingly loud
Quiet suburban

50 Quiet, one-fourth as loud as 70 dB
Quiet rural area 30 Quiet, one-sixteenth as loud at 70 dB

010918wsa HC BOC Page 19
OBSERVATIONS
•Large Caliber PK15 Contours:
–PK15 is a single event measurement for impulsive noise that predicts complaint risk:
•130+ dB = High Complaint Risk
•115 –130 dB = Moderate Complaint Risk
–Measurement based on adverse (noise conducive) weather conditions –representative of 85% of expected events
–130+ dB contour is the primary concern due to high complaint risk for single events.
–130+ dB contour is generally contained within the 62+ dB CDNL contour.
–130 dB + Extends past 62+ dB CDNL in 2 locations along the southern boundary

SMALL ARMS NOISE CONTOURS
010918wsa HC BOC Page 25
OBSERVATIONS
•Small Arms Noise Contours:
–Unweighted event based measurement
–Significant changes in extent of small arms noise contours compared to previous data –previously much smaller / all on-
post.
–Possibly due to changes in measurement of noise levels.
–Small arms noise zones extend off-post a short distance along the
southeastern boundary. BUT –contained within the large caliber
62+ dB CDNL.
–Contours associated with ranges in the western part of the installation extend off-post. Not within any other noise zone.

AVIATION NOISE CONTOURS
010918wsa HC BOC Page 29
OBSERVATIONS
•Aircraft Noise Contours:
–“A” weighted (high frequency) noise contours based on average
daily flight operations with +10 decibel penalty for night operations
–New Simmons AAF noise contours are contained entirely on-post.
–Previous Simmons AAF 65+ dB contour extended off-post.
–Noise contours now available for Mackall AAF.
–Mackall AAF 65+ dB noise contours extend a short distance off-post to
the north, south and west.
–Pope AAF 65+ dB contour extends a shorter distance off-post than the
previous contour.
–Pope AAF noise levels above 70 dB contained almost entirely on-post
now.
