High Risk of Adverse Impact Subzone, where structures, particularly
related to energy development, can interfere with pilot training
missions.
BASH Subzone, where wildlife attractants can pose a risk to
low‐level aircraft overflight.
5‐Mile Military Notification Subzone, where notification of planning
activities to the military is required per state statutes.
Restricted Area Subzone, MTR Subzone, and Military Operations
Subzone, designated areas where structures can interfere with
low‐level aircraft overflight.
This area, illustrated in Figure 28, covers the majority of the northeastern
NC JLUS Study Area counties.
DCR Noise Military Awareness Area (Figure 29)
The Dare County Range Noise MAA includes all land located off‐installation
within the Dare County Range noise contours greater than 65 decibels (dB)
day‐night sound level (DNL) associated with military aircraft activities and
areas subject to low‐level overflight within Military Training Routes,
Restricted Areas and Military Operating Areas throughout northeast
North Carolina. Strategies within the Noise MAA are intended to minimize
community impacts where possible, and increase public awareness of
military airspace, flight operations and communication procedures with
Seymour Johnson AFB and the Dare County Range. The DCR Noise MAA is a
composite of several subzones, each adding a geographic component to the
MAA:
65 dB Noise Contour, where noise has been modeled and quantified
surrounding the DCR.
Restricted Area Subzone, designated areas where low‐level
overflight can generate audible noise on the ground.
MTR Subzone, designated training routes where low‐level overflight
can generate audible noise on the ground.
This area, illustrated in Figure 29, covers large portions of the northeastern
NC JLUS Study Area counties and may not be contiguous.
DCR Vertical Obstruction Military Awareness Area (Figure 30)
The Dare County Range Vertical Obstruction MAA serves to protect areas for
military operations surrounding the Dare County Range and throughout
northeast North Carolina. This MAA includes areas of low‐level aircraft
overflight and the Us Air Force’s High Risk of Adverse Impact Zone (HRAIZ)
where there is a high likelihood of impact to mission requirements by
renewable energy technology. Structures within these areas, depending on
vertical height, proximity to the Dare County Range, siting, and
electromagnetic sensitivity, can restrict navigable airspace and create
obstructions resulting in signal transmission interference for radio frequency
line of sight requirements. Within this MAA, strategies address coordination
procedures to avoid the creation of vertical obstructions to the military
mission. The DCR Vertical Obstruction MAA is a composite of several
subzones, each adding a geographic component to the MAA:
HRAIZ Subzone, where structures, particularly related to energy
development, can interfere with pilot training missions.
Restricted Area Subzone, designated areas where low‐level
overflight can generate audible noise on the ground.
MTR Subzone, designated training routes where low‐level overflight
can generate audible noise on the ground.
This area, illustrated in Figure 30, covers the majority of the northeastern
NC JLUS Study Area counties.
