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 2 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 Attachment 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
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 Zoning Board shall be
responsible for issuing 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 (NLR) to DNL 65db shall be incorporated and considered in individual
approvals. The Building Official shall be responsible for determining adequacy of
attenuation measures.
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 66-70 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 71-75 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 76-80 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 66-70 db range.
19. Residential buildings require the same NLR as required for facilities in DNL 71-75 db range.
20. Residential buildings are not permitted.
21. Land use is not allowed.
For those situations requiring a hearing before the Airport Zoning Board before a permit may be issued,
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.

ATTACHMENT 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.
