Little Rock National Airport
Part of Northwest 1/4, Section 7,

County, Arkansas

Variances are requested from the
height restriction of Section 36-
201, the height regulations of
Section 36-320 and the area
regulations of Section 36-320 to
permit construction of a 150 foot
tall Low Level Windshear Alert
System tower with a reduced
setback.
Airport expansion has rendered the
existing LLWAS inadequate for the
current runway configuration. The
relocation is required for complete
runway coverage and the additional
height will improve the reliability
of information.

B. Staff Analysis:
Recent expansion of the Little Rock National Airport has
rendered the existing Low Level Windshear Alert System
inadequate for the current runway configuration. The
Federal Aviation Administration has proposed relocating the
LLWAS antennae to provide complete runway coverage as well
as increasing the height of the towers to improve the
reliability of information provided.

Item No.: 1 0?±
LLWAS site 1 is currently located between two runways, in
the center of the airport. The LLWAS equipment is currently
mounted on a 20 foot tall steel tower. Under this proposal,
the LLWAS site would be relocated to the northern perimeter
of the airport; just south of the perimeter fence and east
of Falcon Jet. The equipment would be mounted on a 150 foot
tall, monopole tower.
variances are requested to allow for the construction of the
150 foot tall tower and to allow its placement within a 20
foot by 20 foot site directly adjacent to the northern
property line of the airport. Section 36-201 (the tower
ordinance) limits steel, ground -mounted towers to 75 feet in
height and Section 36-320 limits structures to a height of
45 feet in the I-2 District. The I-2 District area
regulations require a 50 foot setback.
The FAA has reviewed the
the LLWAS. As proposed,
runway coverage necessary

the population; staff is

C. Staff Recommendation.:
proposed location and height for
the LLWAS will provide the required
for airline safety. As this is an

setback variances to allow for the construction of a 150
foot tall Low Level Windshear Alert System tower.
