�-C. Regulations herein shall apply within the corporate limits and extraterritorial
jurisdiction of the City of Wichita Falls.
6460 Nonconforming Uses
A. Requlations not Retroactive. The regulations prescribed by this provision shall
not be construed to require changes in land use or the removal, lowering or other
change or alteration of any structure established prior to the regulation as of
October 31, 1982 or otherwise interFere with the continuance of any
nonconforming use.
B. Marking and Lighting. Notwithstanding provisions herein, the owner of any
nonconforming structure is hereby required to permit the installation, operation
and maintenance thereon of such markers and lighting as shall be deemed
necessary by Sheppard Air Force Base and/or Wichita Falls Municipal Airport or
the City of Wichita Falls to indicate to the operators of aircraft in the vicinity of the
airport, the presence of such airport hazards. Such markers and lights shall be
installed, operated and maintained at the expense of the City of Wichita Falls
and/or Sheppard Air Force Base.
C. Reconstruction. Any nonconforming use which is damaged or destroyed by fire,
flood, explosion, wind, earthquake, war, riot, or other calamity may be
reconstructed and used as it was before such happening.
6465 Permits
B. New Construction. A permit shall be required to construct a structure in any
Accident Potential Zone, Noise Zone, or Height Restriction Zone established by
this provision as specifically provided herein. Each application for a permit shall
indicate the location, height, and if applicable, use of the structure, with sufficient
particularity to enable it to be determined whether the resulting structure would
conform to the regulations herein prescribed. If such determination is in the
affirmative, the permit shall be granted. No permit for a structure inconsistent
with these provisions shall be granted unless a variance has been approved in
accordance with Subsection C of this section.
1. In the limits of the Accident Potential Zones (APZ I& II), a permit shall be
required for any structure. Such permits shall be issued when the
proposed use of the structure is permitted, and the vertical height of the
structure above the ground does not exceed the height limits prescribed
herein.
a) In the area lying inside the Accident Potential Zones (APZ I& II), a
permit shall be required for any use or structure. Such permits shall
be issued when the vertical height of the structure, above the
ground, does not exceed the height limits prescribed herein and is
found to be a compatible use as defined herein.
b) In the area lying outside the Accident Potential Zones (APZ I& II)
and within a height restriction zone, a permit shall be required for
any use or structure. Such permits shall be issued when the vertical
height of the structure, above the ground, does not exceed the
height limits prescribed herein and is found to be a compatible use
as defined herein.
2. In the area within the 65db or greater noise contour as shown in the latest
AICUZ study for Sheppard Air Force Base , a permit
shall be required for any use or structure as identified in the Land Use
Compatibility Table included herein as requiring noise attenuation. Such
permits shall be issued when the Building Official has approved noise
attenuation measures on those uses requiring attenuation as identified
herein.
No Certificate of Occupancy (CO) shall be issued for commercial
properties until such time compliance is realized through inspection and
approval by the Building Official for compliance with noise attenuation
measures as required herein. For residential land uses required to
attenuate, no water sales by the City or appropriate water districts or
supply corporations shall be permitted until compliance is realized through
inspection and approval of the Building Official.
Noise attenuation measures as required herein, and as approved by the
Building Official, shall be installed and maintained at the same level of
attenuation as required by this provision.
B. Existinq Uses.
1. No permit shall be granted that would allow the establishment or
creation of any airport hazard or permit a nonconforming use or
structure to be made higher or become a greater hazard to air
navigation, than it was on the effective date of this ordinance.
2. No permit shall be granted that would allow the expansion of a use
not herein permitted within the Noise Zone unless said use adheres
to attenuation measures as required.
C. Variances. Any person desiring to erect or increase the height of any structure,
or use his property contrary to the regulations prescribed in this provision may
apply to the Board of Adjustment for a variance from such regulations in
question. The application for variance from a height restriction shall be
accompanied by a determination from the Federal Aviation Administration as to
the effect of the proposal on the operation of air navigation facilities and the safe,
efficient use of navigable airspace. A variance request shall be processed in
accordance with Section 7300 of this ordinance.
D. Obstruction Markinq and Lightinq. Any permit or variance granted may, if such
action is deemed advisable by the Director of Community Development or his
designee or the Board of Adjustment to effectuate the purposes of this provision
and is reasonable under the circumstances, be so conditioned as to require the
owner of the structure in question to install, operate and maintain, at their
expense, such markings and lights as may be necessary.
6475 Enforcement
It shall be the duty of the Director of Community Development or his designee to
administer and enforce the regulations prescribed herein. Applications for permits shall
be made to the Director of Community Development or his designee. Applications
required by this provision to be submitted to the Director of Community Development or
his designee shall be promptly considered and granted or denied by him. In the event
that the Director of Community Development or his designee refuses to grant the
application, the applicant may appeal such decision to the Board of Adjustment.
Applications for variances shall be made to the Board of Adjustment by first filing said
application for variance with the Director of Community Development or his designee
who shall forthwith transmit said application to the Board of Adjustment for
determination.
6480 Airport Board of Adjustment
An Airport Board of Adjustment shall be appointed comprised of both residents of the
City of Wichita Falls, and residents located outside of the City but within the area
affected by this ordinance, and accordance with the provisions of the Local Government
Code. The Board shall consist of five members, three of whom shall be residents
located outside the City, but within the area affected by this ordinance, who shall serve
two-year staggered terms commencing on December 31. The City's resident members
located outside the City shall be appointed in even-numbered years, and the members
located outside the City shall be appointed on odd-numbered years. The actions and

NLR (outdoor to indoor) to be achieved throuqh incorporation of noise
attenuation measures into the desiqn and construction of the structures.
A, B, or C
Land use and related structures generally compatible; measures to achieve NLR
for A(DNL 66-70), B(DNL 71-75), C(DNL 76-80�, need to be incorporated into
the desiqn and construction of structures and approved by the Buildinq Official.
A B C
Land use qenerally compatible with NLR. However, measures to achieve an
overall noise level reduction do not necessarily solve noise difficulties and
additional evaluation is warranted. See appropriate footnotes.
*
The designation of these uses as "compatible" in this zone reflects individual
federal aqencies' and program considerations of general cost and feasibility
factors, as well as past community experiences and proqram obiectives. The
Airport Zoning Board shall review request and be responsible for issuinq
necessarypermits based on its findings.
NOTES
1. Maximum density of 2 dwellinq units per acre or lot coveraqe less than 20
percent, whichever is reg ater.
2. Within each land use cateqory uses exist where further definition may be
needed due to the variation of densities in people and structures. (See Exhibit R
included herein}
3. No buildings, structures or above-qround utilities shall be placed within the area
defined as the Clear Zone.
4. No passenqer terminals and no major above-ground transmission lines in APZ 1.
5. Factors to be considered: labor intensitv, structural coverage, explosive
characteristics, and air pollution. The proposed use shall be evaluated by the
Director of Cammunity Development or his designee in conference with the base
AICUZ officer for Sheppard Air Farce Base or desiqnated personnel.
6. Low-intensity office uses on�. Meetinq places, auditoriums, etc. shall not be
permitted. For the purpose of this provision, low-intensity is defined as an
emplovment population not to exceed twenty five (25�people per acre per shift.
7. Excludes chapels.
8. Facilities must be low intensity. For the purpose of this provision, low-intensity is
defined as an employment population not to exceed twenty five (25) people per
acre per shift.
9. Clubhouse not permitted.
10. Areas for gatherings of people are not recommended. The Airport Zaning Baard
shall be responsible for issuinq the necessary permit based on its findings.
11. a. Residential use is discouraged in DNL 66-75dB and prohibited in DNL
above 75db.
b. Where residential uses are allowed measures to achieve outdoor to
indoor Noise Level Reduction {NI.R) to DNL 65dB shall be incorporated
and considered in individual approvals. The Building Official shall be
responsible for determininq adequacy af attenuation measures.
NLR criteria will not eliminate outdoor noise problems. However, building
location and site planning and desiqn, and use of berms and barriers may help
miti�ate outdaor exposure, particularly fram near ground level sources.
Measures that reduce outdoor noise shall be used whenever practical in
preference to measures which onl�protect interior spaces. Such measures shall
be indicated on a site plan and evaluated prior to approval of the required permit.
12. Measures to achieve the same NLR as required for facilities in DNL 66-70 dB
ranqe shall be incorporated into the design and construction of portions of these
buildings where the public is received, office areas, noise sensitive areas or
where the normal noise level is low.
13. Measures to achieve the same NLR as required for facilities in DNL 71-75 dB
ranqe shall be incorporated into the design and construction of portions of these
buildings where the public is received, office areas, noise sensitive areas or
where the normal noise level is low.
14. Measures to achieve the same NLR as required for facilities in DNL 76-80 dB
ranqe shall be incorporated into the design and constructian of portions of these
buildinqs where the public is received, office areas, noise sensitive areas or
where the normal noise level is low.
15. If naise sensitive, use appropriate NLR. If not noise sensitive the use is
compatible.
16. No buildinqs.
17. Land use is compatible provided special sound reinforcement systems are
installed as approved by the Building Official.
18. Residential buildinqs require the same NLR as reauired for facilities in DNL 66-
70 dB ranqe.
19. Residential buildinqs require the same NLR as required for facilities in DNL 71-
75 dB ranqe.
2Q. Residential buildings are not permitted.
21. Land use is not allowed.
For those situations requiring a hearinq before the Airport Zoninq Board before a permit
may be issued, the Director of Community Development or his designee may require
buildinq elevations, buildinq plans, landscape plans and other details to allow for proper
evaluation of the proposed use in order to ensure the protection of the publics health,
safety and welfare.
EXHIBIT A
Uses are compatible if they do not result in a gathering of individuals in an area that
would result in an average density of greater than 25 persons per acre per hour during
a 24-hour period, not to exceed 50 persons per acre at any time.
The following is a reproduction of Appendix F, Volume II of the 1992 AICUZ study for
Sheppard Air Force Base, and is included here for ease of reference.
Average Density
Average densities of persons per hour during a 24-hour period are determined by
calculating the number of persons per acre expected on a site, multiplying by the
number of hour they will be on the site, and dividing the total by 24.
- Example #1. One 8-hour shift of 30 workers on a one acre site.
Avg. density = 30 persons expected X 8 hours on site = 240
Then 240/24=10: Thus avg. density = 10 persons per hour per 24-hour period.
- Example #2. Two 8-hour shifts of 30 workers on a one acre site.
Avg. density = 30 persons expected X 16 hours on site = 480
Then 480/24=20: Thus avg. density = 20 persons per acre per hour per a 24-
hour period.
Maximum Density
The maximum number of persons allowed per acre per hour is calculated by dividing
the number of hours persons will be on site by 24 hours, and then dividing by 25
persons per acre per hour by the result. The resulting number is the maximum number
of persons allowed per acre per hour, provided it does not exceed 50. Fifty persons per
acre at any one time is the maximum number of persons allowed under the standard.
- Example. Maximum density for two 8-hour shifts on a one acre site.
25 divided by 16/24 = 37.5 persons per hour allowed.
Application of this formula results in the following table which specifies the maximum
persons per acre per hour for the duration of the time that persons are expected to be
on site during a 24-hour period.
