AN ORDINANCE REGULATING AND RESTRICTING THE HEIGHT OF STRUCTURES AND
OBJECTS OF NATURAL GROWTH, AND OTHERWISE RESTRICTING THE USE OF PROP-
ERTY ON AND IN THE VICINITY OF THE DALLAS-FORT WORTH REGIONAL AIRPORT:
BY ESTABLISHING AIRPORT APPROACH ZONES, TRANSITION ZONES, HORIZONTAL
ZONES, AND CONICAL ZONES, AND ESTABLISHING THE BOUNDARIES THEREOF;
PROVIDING FOR AMENDMENTS OR CHANGES IN THE RESTRICTIONS AND BOUNDA-
RIES OF SUCH ZONES; DEFINING CERTAIN TERMS USED HEREIN; REFERRING TO THE
DALLAS-FORT WORTH REGIONAL AIRPORT ZONING MAP WHICH IS INCORPORATED

LISHING A BOARD OF ADJUSTMENT; PROVIDING FOR JUDICIAL REVIEW; AND
IMPOSING PENALTIES.
This ordinance is adopted pursuant to the authority conferred by the Airport Zoning Act,
Article 46e, V.A.C. S., as amended by all subsequent legislation. It is hereby found that
an airport hazard endangers the lives and property of users of the Dallas-Fort Worth Regional
Airport and occupants of land in its vicinity, and also, if of the obstruction type, in effect
reduces the size of the area available for the landing, taking-off and maneuvering of air-
craft, thus tending to destroy or impair the utility of the Dallas-Fort Worth Regional Airport
and the public investment therein. Accordingly, it is declared: (1) that the creation or
establishment of an airport hazard is a public nuisance and an injury to the region served by
the Dallas-Fort Worth Regional Airport; (2) that it is necessary in the interest of the public
health, public safety and general welfare that the creation or establishment of airport haz-
ards be prevented; and, (3) that the prevention of these hazards should be accomplished, to
the extent legally possible, by the exercise of the police power without compensation. It
is further declared that both the prevention of the creation or establishment of airport hazards
and the elimination, removal, alteration, mitigation, or marking and lighting of existing
airport hazards are public purposes for which political subdivisions may raise and expend
public funds and acquire land or interest in land.

The dimensions, elevations above mean sea level, slopes and radii applicable to the imagin-
ary surfaces shall be as shown on the Zoning Map.

angles to the runway centerline.
SECTION V: HEIGHT LIMITATIONS
Except as otherwise may be provided in these regulations, no structure, tree, or installation
shall be erected, altered, allowed to grow, or be maintained within the Airport Hazard
Zoning Area which will be above the imaginary surfaces as established by and shown on the
Zoning Map.
SECTION VI: USE RESTRICTIONS
Notwithstanding any other provision of these regulations, no use may be made of land or
water nor installation placed on land or water within the Airport Hazard Area that will cre-
ate interference with radio communication between the Airport and Aircraft; or that will
create interference with any air navigation facility, airport visual approach or landing aid,
aircraft arresting device, or meteorological device; or that will result in glare in the eyes
of flyers using the airport but this prohibition shall not include momentary glare or glare
from vertical or downward reflecting windows or glass panels used in the construction of
structures; or that will impair visibility in the vicinity of the airport, attract birds, or that
will otherwise endanger the landing, taking-off or maneuvering of aircraft operating
3
through the facilities of the airport. No other airport or landing field shall be constructed
within the airport hazard area.
SECTION VII: EXISTING NON-CONFORMITIES
Structures, trees or installations existing prior to the effective date of these regulations
which do not conform to the requirements hereof shall be considered as legal non-conforming
uses. These regulations shall not be construed to require the removal, lowering, change or
alteration of any legal non-conforming use structure, tree or installation. A permit shall
be required for a legal non-conforming use and shall be issued on application of the owner
or agent accompanied by affidavit that the use, structure, tree or installation was in exist-
ence on the effective date of these regulations. Applications for permits for non-conforming
users shall be made within 180 days from the effective date of these regulations.
SECTION VIII: PERMITS REQUIRED
Before any new structure or use which could be defined as an airport hazard under this
ordinance may be constructed or established and before any such existing use or structure
may be increased in height or otherwise altered, a permit to do so must be secured by the
owner involved or his agent. All permit applications shall be made to the administrative
agency having jurisdiction, or their designated representatives under Section XII hereof.
In the event that any administrative agency issues a permit erroneously allowing the begin-
ning of erection of any structure or tree, said permit shall not constitute a variance or be
construed in any manner to allow any person to penetrate the imaginary surfaces established.
It will remain incumbent on the sponsor, builder, property owner or their agents, as the case
may be, to prevent the creation of any object that will cause an airport hazard within the
meaning of this ordinance. When said permits are requested for construction and/or alter-
ation within the city limits of a municipality the administrative agency having jurisdiction
shall be the municipality itself and the county administrative agency shall have no juris-
diction within the city limits of municipalities.
SECTION IV: NOTICE TO FEDERAL AVIATION ADMINISTRATION
Nothing in these regulations shall be construed as relieving any owner, sponsor, or agent
from the requirement for filing a notice of proposed construction or alteration with the ap-
propriate Federal Aviation Administration Authority.
SECTION X: VARIANCES
Any person desiring to erect any structure or increase the height of any structure, or permit
the growth of any tree, or otherwise use his property in violation of these regulations may
apply to the Board of Adjustment for a variance from the zoning regulations in question.
Such variances shall be allowed where a literal application or enforcement of the regula-
tions would result in practical difficulty or unnecessary hardship and the relief granted would
not be contrary to the public interest but do substantial justice and be in accordance with
the spirit of these regulations; provided that any variances allowed shall be subject to any
reasonable conditions that the Board of Adjustment may deem necessary to effectuate the
purposes of these regulations.
4'
SECTION XI: HAZARD MARKING AND LIGHTING
Any permit granted under these regulations may, if such action is deemed advisable to
effectuate the purposes of these regulations and reasonable in the circumstances, be so
conditioned as to require the owner of the structure, tree or installation in question to
permit the proper authority to install, operate and maintain thereon such markers and
lights, as the Board may find necessary to indicate the presence of the Airport Hazard.
SECTION XII: ADMINISTRATIVE AGENCIES
The administration and enforcement of all regulations adopted by the Joint Airport Zoning
Board is vested in the governing bodies of each of the political sub-divisions represented
on the Board, and who have adopted the regulations each respectively by ordinance.
Each political subdivision shall:
(1) Establish its own administrative and enforcement agency; or
(2) Designate another political sub-division to administer and enforce these regula-
tions in its behalf; or
(3) Request the Joint Airport Zoning Board to designate an agency to act in this
capacity in its behalf.

ings shall not be stayed otherwise than by order of the Board of Adjustment on notice
to the Administrative Agency and on due cause shown.
