Narrative Factors Associated With Aircraft Sound Exposure Map
D/FW Airport and Environs
October 14, 1971
I. SOUS? EXPOSURE FORECAST
This map indicates forecasted zones of perceived sound resulting from air-
craft operations at the Dallas/Fort Worth Regional Airport from opening to
that point in time where the activity now precast for 1985 is reached. The
degree of exposure to aircraft sound will diminish with distance from the
airport runways and flight tracks.
The bands om the map represent areas where sound exposure is anticipated
to be equal, in much the same way as contour lines are used on topographic
maps to mark off Points of equal elevation. Unlike topographic contours,
however, the bands do not represent measured intensities, but are broad
asDroximations of boundaries between the zones explained below.
II. !NTER~RETATI3N OF MAP
In the interpretation of the mad a number of points should be kept in
mind. The map reflects current forecasts of aircraft operations through
19~. Zones shown are based upon the experiences of other regions. Changes
in aircraft desi?, flight characteristics, or level of operations will
alter the affected areas.
it has not been possible to take into consideration many of the factors (such
as elevation, buffers, or tree cover) that influence perceived sound. Also,
the map considers only aircraft related sound. The impact of other major
sound producers, such as freeways and railroads, have not been included in
the evaluation.
Furthermore, it should be noted that the sound areas identified on this mad
represent only one consideration among the many that must be judged by local
officials in drawing up planning and zoning regulations in the vicinity of
the Airport. Specific inquiries concerning the permitted used of land should
be directed to appropriate local officials.

AIRPORT ENV!RONS LAND USE GUIDELINES
Zone A - Zone of minimal effect. Few activities will be affected by air-
craft sounds except for especially sound-sensitive activities (such as
auditoriums, churches, schools, hospitals, and theatres) in areas closest
to the airport shown by the narrow dashed band. Sound control should be
considered in the building design of such activities. Also in areas
closest to the airport, open air activities may be disrupted. Detailed
studies by qualified personnel are recommended for outdoor amphitheatres
and like places of public assembly throughout the mid-cities area. Other-
wise, so far as aircraft sound is concerned, generally all uses may be
acceptable.
Zone B - Middle zone of effect. Activities where uninterrupted communi-
cation is essential should consider sound exposure in design. Generally,
residential development is not considered a suitable use although multi-
family developments where sound control features have been incorporated
in building design might be considered. Open-air activities and outdoor
livina must consider aircraft sound. The construction of auditoriums,
schools, churches, hospitals, and theatres and like activities should be
avoided within this zone where possible.
The following types of uses may generally be considered without any special
sound treatment: agricultural uses, mining, fishing; wholesal~ commercial
and some retail; industrial manufacturing, transportation, communication
and utilities; cemeteries.
The following types of uses may be considered without any special sound
treatment except when near Zone C: livestock farming and animal breeding;
gol{ courses, riding stables, water-baseS recreational areas and cemeteries.
The following types of uses may be considered onlS if sound treatment is
included in building desigq: multi-family apartments, dormitories, grouo
quarters, orphanages, retirement homes, etc.; transient lodging, e.g.,
motels and hotels; office buildings, personal, business and professional
services; retail commercial, movie theatres, restaurants; and noise-sensitive
types of manufacturing and communications uses. In locations close to the
Zone C boundary, consideration should be given to the limitations set forth
in the following paragraph.
Zone C - Zone of greatest effect. Land should be reserved for activities
that can tolerate a high level of sound exposure such as some agricultural,
industrial and commercial uses. Such sound sensitive activities as schools,
offices, hospitals, churches, and like activities should not be constructed
in this area. No residential developments of any type are recommended. All
regularly occupied structures should consider sound control in design.

RESOLUTION NO. 82-169
WHEREAS, the Dallas/Fort Worth Airport has experienced a continuing increase in
aircraft activity in accordance with its early forecast and public reports; and
WHEREAS, the Dallas/Fort Worth Airport Board maintains a continuous Interest in the
well being of the citizens of our neighboring cities and in preserving the Dallas/Fort
Worth Airport's master planned expansion capability; and
I&'HEREAS, the cities surrounding Dallas/Fort Worth Airport, initially zoned these areas
to prevent or minimize the environmental impact on them; and
WHEREAS, in some cities those planned and zoned areas are being incrementally eroded
to the future detriment of their citizens and of the Airport in its efforts to provide
transportation services for the continuing economic growth of the metroplex;
NOW, THEREFORE, BE IT RESOLVED BY THE DALLAS-FORT WORTH REGIONAL
AIRPORT BOARD:
SECT]ON ] That the Cities of Arlington, Bedford, Colley~rille, Coppel], Dallas, Euless,
Flower Mound, Fort Worth, Grand Pratie, Grapevine, Irving', LewisviUe, South Lake; West
Lake, and the Counties of Dallas, Denton, and Tarrant be advised of the Board's interest
and concern regarding zoning actions which permit deterioration of the planned land use
in the vicinity of the Dallas/Fort Worth Airport.
SECTION 9_ That of specific concern is the development of residential areas within the
65 LDN noise contour (Zone B Noise Exposure Forecast Contour as depicted in the
"Aircraft Sound Exposure: Dallas/Fort 9,'orth Regional Airport and its Environs," October
14, 1971, North Central Texas Council of Governments), and the development of tall
structures which would be in conflict with the various city and county ordinances
pertaining to the '~Hazard Zoning Maps For the Dallas/Fort Worth Airport".
s£CTIOlq 3 That the named local government units be advised of the Board's concern by
copy of this resolution; and, further these local governments be once again presented
w/th copies of the aforementioned ''Aircraft Sound Exposure: Dallas/Fort Worth Regional
Airport and £nvirons' and the "Hazard Zoning Maps for the Dallas/Fort Worth Regional
Airport".
SECTION 4 That the purpose of this action is to advise local governments of the Board's
intent (1) to specifically encourage local governments to protect the environmental
welfare of their citizens and their economic growth; and (2) to assure the potential
expansion of service to the Metroplex in general, by maintaining land-use which is
compatible with the development of the Dallas/Fort Worth Airport Master Plan.
SECTION 5 That this Resolution shall take effect immediately upon its passage.
