Land Use Compatibility Matrix
Navy - Community Partnership
In each zone, or combination of zones, many activities
can occur without negative health, safety, or welfare
impacts. The compatibility tables above summarize
suggested residential land uses in noise zones and APZs.
“Y” means a use is generally compatible, “N” means the
use is generally incompatible and a superscript number
means see that note in the AICUZ Study Update. Tables
for retail, commercial, industrial and agricultural land
uses are also in the AICUZ Study Update.
The Navy needs to assure compatible land uses within the
AICUZ footprint to retain operational capabilities necessary
to support current and future missions. The community’s
land use regulatory agency needs to enact land use controls
to ensure the highest degree of health, safety and welfare of
their constituents. The two goals are complimentary. Both
Island County and the City of Oak Harbor have longestablished land use and development controls that promote
land uses compatible with ongoing flight operations at NAS
Whidbey Island and ensure the highest degree of health,
safety and welfare for their respective communities.
Cooperation is the key to achieve the goals of compatible
land uses in the Navy’s AICUZ Program and a community’s
Comprehensive Land Use Plan.
Island County and Oak Harbor have special land use
regulations for aviation overlay zones that are not the
same as this AICUZ footprint. Check with the County or
City planning department(s) for specific fair disclosure,
development, construction, lighting and structural/object
height regulations in the overlay zones they’ve adopted.

Program at NAS Whidbey Island, you may contact
the air station’
station’s Community Planning and Liaison
Officer (CP&LO) at 360360-257257-3315.
The AICUZ “footprint” combines APZs and Noise Zones.
It represents the nominal area where land use controls are
needed to minimize accident potential and noise
annoyance impacts on underlying areas.

Height limitations should be applied in areas where the
height of structures or trees is a safety hazard to flight
operations at the airport. Local zoning controls should
limit the height of buildings, structures, and obstructions in
these areas to ensure safety of flight, to ensure flight tracks
don’t need to be relocated and to protect the safety and
welfare of people on the ground.

Noise Zones 1, 2, and 3 represent progressively higher
annual average day-night weighted noise exposure levels
(DNL) generated from the intensity and location of air
operations, aircraft type and mix, flight characteristics, etc.
Noise Zone (NZ) 1 is all areas below 65 decibels (dB)
DNL. Noise may interfere occasionally with certain
activities in NZ 1 (phone calls, speech communication,
listening to TV or radio shows, etc.). Noise disclosure
notices should be required to inform prospective real
estate buyers, lessees or renters that aircraft noise may
annoy some individuals or interfere with some activities in
NZ 1 even though noise levels are not high enough to
annoy the community as a whole. Aircraft noise may
periodically interfere with speech, listening to TV or radio
shows and sleep in NZ 2 so special sound attenuation for
residences, offices, etc. is recommended for habitable
structures that must be located in NZ 2 in addition to
disclosure. The Federal government recommends no
residential development in NZ 3 due to the high potential
for noise to regularly interfere with communications, sleep
and other residential activities in this area.

Accident Potential Zones (APZ) represent the most likely
impact areas if an aircraft accident occurs, not the
probability of an accident. APZs are based on historical
accident data throughout the Department of Defense.

Air Installations Compatible Use Zones (AICUZ) is a
Department of Defense program to achieve compatibility
between air installations and neighboring communities by
preventing incompatible development in high noise
exposure zones; minimizing public exposure to potential
safety hazards associated with aircraft operations; and
assuring the future operational capabilities of the airfields.
