In order to carry out the provisions included herein as it pertains to height restrictions, there are established certain height restriction zones which include all of the land lying beneath the approach-departure surface, inner horizontal surface, conical surface, outer horizontal surface, and transitional surface as they apply to Sheppard Air Force Base/Wichita Falls Regional Airport. Such zones and height restrictions are shown in the most recent AICUZ study of Sheppard Air Force Base. The various zones are established and defined as follows:
A. 
Zones related to runways.
1. 
Primary zone (A zone).
All of the land area lying beneath a primary surface, which is a surface on the ground centered lengthwise of the runway and extending 200 feet beyond each end of that runway. The width of the primary surfaces are:
a. 
For runway 17/35: 1,000 feet.
b. 
For runways 15R/33L, 15C/33C, and 15L/33R: 2,000 feet.
No structure is permitted within the primary zone (A zone) as described herein.
2. 
Clear zone (B zone).
All of the land area lying beneath a clear zone surface, which is a surface on the ground beginning at the runway end and symmetrical with the runway centerline extended. The width and length of the clear zone surfaces are:
a. 
For runway 17/35: 1,000 feet wide and 3,000 feet long.
b. 
For runways 15R/33L, 15C/33C, and 15L/33R: 3,000 feet wide and 3,000 feet long.
3. 
Approach/departure zone (C and D zones).
All of the land area lying under an approach/departure surface, which is an inclined plane or combination inclined plane and horizontal plane, symmetrical about the runway centerline extended. The inclined plane flares outward and upward from the primary surface or planned expansion, and begins with the centerline elevation of the runway end. The slope ratio and dimensions of the inclined planes (C zone) and dimensions of the horizontal planes (D zone) are as follows:
a. 
Runway 17/35: one foot in height for each 40 feet in horizontal distance beginning at the runway ends. The runway end centerline elevations are 1,001 feet mean sea level (MSL) and 1,014 feet MSL for runways 17 and 35, respectively. The surface extends to a point 10,200 feet from the respective runway ends with an inner width of 1,000 feet and an outer width of 6,466 feet. The maximum elevations for the approach/departure clearance zones are 1,256 and 1,269 feet MSL for runways 17 and 35, respectively.
b. 
Runway 15R/33L: one foot in height for each 50 feet in horizontal distance beginning at the end of the primary surfaces and at the centerline elevation of the runway end. The runway end centerline elevation is 998 MSL feet for runway 15R and 1,000 MSL feet for 33L. The surfaces extend until they reach an elevation of 500 feet above established airfield elevation (1,515 MSL). They then continue horizontally at this elevation to a point 50,000 feet from the point of beginning. The outer width is 16,000 feet.
c. 
Runway 15C/33C (formerly 15L/33R): one foot in height for each 50 feet in horizontal distance beginning at the end of the primary surfaces and at the centerline elevation of the runway end. The runway end centerline elevation is 1,003 MSL feet for runway 15C and 989 MSL feet for runway 33R. The surfaces extend until they reach an elevation of 500 feet above established airport elevation (1,515 MSL). They then continue horizontally at this elevation to a point 50,000 feet from the point of beginning. The outer width is 16,000 feet.
d. 
Runway 15L/33R: one foot in height for each 50 feet in horizontal distance beginning at the end of the primary surface centerline elevation of the runway end. The runway end centerline is 1,021 MSL feet for runway 15L and 996.9 MSL for runway 33R. The surfaces extend until they reach an elevation of 500 feet above established airport elevation (1,515 MSL). They then continue horizontally at this elevation to a point 50,000 feet from the point of beginning. The outer width is 16,000 feet.
B. 
Zones related to airport reference points.
1. 
Inner horizontal zone (E zone).
All of the land lying beneath the inner horizontal surface, which is an oval-shaped plane at a height of 150 feet above the established airfield elevation (1,165 MSL). It is constructed by scribing an arc with a radius of 7,500 feet about the centerline at each end of each runway and interconnecting these arcs with tangents.
2. 
Conical zone (F zone).
All of the land area lying beneath the conical surface, which is an inclined plane that extends from the periphery of the inner horizontal surface outward and upward at a slope of 20 to one for a horizontal distance of 7,000 feet to a height of 500 feet above the established airfield elevation (1,515 MSL).
3. 
Outer horizontal zone (G zone).
All of the land area lying beneath the outer horizontal surface, which is an oval-shaped plane located 500 feet above the established airport elevation (1,515 MSL), extending outward from the outer periphery of the conical surface for a horizontal distance of 30,000 feet.
4. 
Transitional zone (H zone).
All of the land area lying beneath a transitional surface, which are inclined planes that connect the primary surface and the approach-departure clearance surfaces to the inner horizontal surface, conical surface, outer horizontal, or other transitional surfaces. The slope is one foot in height for each seven feet in horizontal distance outward and upward at right angles to the runway centerline and runway centerline extended. To determine the elevation for the beginning of the transitional surface slope at any point along the lateral boundary of the primary surface, draw a line from the point, perpendicular to the runway centerline or to the runway centerline extended. The elevation of the runway or the runway centerline extended at that intersection is the elevation for the beginning of the seven to one slope.
5. 
Except as otherwise provided in this provision, no structure or obstruction shall be erected, altered or maintained in any zone created by this provision to a height in excess of the applicable height of the surface used to describe such zone.

A. 
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 and 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 and 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 and 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 65 dB 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. 
Existing 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.
D. 
Obstruction marking and lighting.
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.
(Ordinance 155-94, sec. 1, adopted 12/20/94; Ordinance 72-2000, sec. 2, adopted 7/5/00; Ordinance 32-2001, sec. 14, adopted 4/3/01; Ordinance 8-2006, sec. 1, adopted 2/7/06)

LEGEND
SLUCM: Standard Land Use Coding Manual, U.S. Department of Transportation.
Y (Yes): Land use and related structures are compatible without restriction.
N (No): Land use and related structures are not compatible and shall be prohibited.
Yx (yes with restrictions): Land use and related structures generally compatible; see notes 1 through 21.
Nx (no with exceptions): See notes 1 through 21.
NLR (Noise Level Reduction): NLR (outdoor to indoor) to be achieved through incorporation of noise attenuation measures into the design 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 design and construction of structures and approved by the building official.
Ax, Bx, and Cx: Land use generally 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 agencies’ and program considerations of general cost and feasibility factors, as well as past community experiences and program objectives. The Airport Zoning Board shall review request and be responsible for issuing necessary permits based on its findings.
NOTES
1.
Maximum density of one–two dwelling units per acre or lot coverage less than 20 percent, whichever is greater.
2.
Within each land use category, uses exist where further definition may be needed due to the variation of densities in people and structures (see Exhibit A included herein).
3.
No buildings, structures or above-ground utilities shall be placed within the area defined as the clear zone.
4.
No passenger terminals and no major above-ground transmission lines in APZ 1.
5.
Factors to be considered: Labor intensity, structural coverage, explosive characteristics, and air pollution. The proposed use shall be evaluated by the director of community development or his designee in conference with the base AICUZ officer for Sheppard Air Force Base or designated personnel.
6.
Low-intensity office uses only. Meeting places, auditoriums, etc. shall not be permitted. For the purpose of this provision, low-intensity is defined as an employment population not to exceed 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 25 people per acre per shift.
9.
Clubhouse not permitted.
10.
Areas for gatherings of people are not recommended. The director of community development shall be responsible for issuing the necessary permit based on his findings.
11.
a.
Residential use is discouraged in DNL 65-69dB, strongly discouraged in DNL 70-75dB as allowed in 11.b and prohibited in DNL above 75dB.
 
b.
Where residential uses are allowed, measures to achieve outdoor to indoor noise level reduction (NLR) to DNL 65dB shall be incorporated and considered in individual approvals. The building official shall be responsible for determining adequacy of attenuation measures.
 
c.
NLR criteria will not eliminate outdoor noise problems. However, building location and site planning and design, and use of berms and barriers, may help mitigate outdoor exposure, particularly from near ground level sources. Measures that reduce outdoor noise shall be used whenever practical in preference to measures which only 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 65-69 dB range 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 70-74 dB range 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 75-79 dB range 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.
15.
If noise sensitive, use appropriate NLR. If not noise sensitive the use is compatible.
16.
No buildings.
17.
Land use is compatible provided special sound reinforcement systems are installed as approved by the building official.
18.
Residential buildings require the same NLR as required for facilities in DNL 65-69 dB range.
19.
Residential buildings require the same NLR as required for facilities in DNL 70-79 dB range.
20.
Residential buildings are not permitted.
21.
Land use is not allowed.
The director of community development or his designee may require building elevations, building 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 H, 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.t
Example #1. One 8-hour shift of 30 workers on a one acre site.
Avg. density = 30 persons expected × 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 × 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 eight-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.
