11.3.6.2 Fences

Fences should be utilized for screening of service areas and site utilities, screening dumpsters, containment, and security. See the trash enclosure section on fencing requirements at those locations.

11.3.6.2.1 Fence Locations

All Army installations should install fences and screens in accordance with the standards in this chapter and adhere completely with the provisions of UFGS - 02821A. Fences are necessary to protect property, define boundaries, and conceal unsightly equipment. Fence styles should be compatible with the established visual zones.

Perimeter fences will be installed at all posts where encroachment or civilian intrusion may occur. Perimeter fences will normally be a minimum of seven (7) feet high and may be chain link, decorative metal, masonry, concrete, or a combination thereof. The perimeter fence will establish a legal boundary and a physical barrier to unauthorized entry. Chain link is not to be used adjacent to any entrance gate. Provide decorative fencing directly adjacent to the gate facilities and convert to chain link a minimum of 100’ from the gate. All perimeter fencing must meet antiterrorism requirements.

11.3.6.2.2.2 Security Fences

Security fences interior to the post boundary should be minimized and present the appropriate degree of security for the resources being protected. These fences may be chain link, decorative metal, masonry, concrete, or a combination thereof.

11.3.6.2.2.3 Chain Link Fences

With few exceptions, chain link fencing should be used only for perimeter boundaries, security for restricted or controlled areas, and in some industrial areas. Chain link fencing may also be appropriate for Military Family Housing to define yards and restrain small children or pets. If chain link is used, outriggers with three-strand barbed wire and/or concertina wire should only be used for designated permanent restricted areas or where dictated by security needs. The chain link fence should be corrosion resistant material to reduce maintenance. Coated fence fabric is recommended, and where used, fence posts must be coated with the same material. Wood, metal, or vinyl slats will not be used in chain link fencing. When concealment of structures or equipment is a primary purpose of the fence, a type other than chain link should be used. Chain link fencing should be avoided as much as possible in the cantonment area. If chain link fencing is necessary, utilize plantings such as trees and shrubs to screen the fencing from view.

11.3.6.2.2.4 Metal Fences

Metal fencing can be used if it is compatible with the post’s visual zones. The type of metal fencing should be corrosion resistant to reduce maintenance. Barbed wire fence is discouraged, but may occasionally be appropriate, such as in areas where government land is leased for grazing purposes. Decorative metal fencing can be used as appropriate around administration facilities. Where screening of industrial areas is important, a vertical metal slat fence is a good option.

11.3.6.2.2.5 Wooden Fences

Wooden fencing can be an alternative for screening, but should be evaluated for life cycle cost when compared to a permanent material. When used, wooden fences should be stained or treated to complement adjacent color schemes and to reduce maintenance. Consider the use of galvanized metal posts in lieu of wood. Wood fences are most appropriate in recreational and housing areas. Typically, wood fencing is discouraged at Fort Carson due to its shorter life span and high maintenance costs.

11.3.6.2.2.6 Masonry and Concrete Fences

Masonry and concrete fences are attractive and durable, but have a higher initial cost, and thus should be used accordingly. However, they may compare favorably on life cycle costs. They should be used when screening is a primary function of the fence. The materials used must match adjacent facilities and comply with the IDG. Long masonry walls are very monotonous and should be staggered, or otherwise articulated in a manner that visually breaks up the monotony. Masonry walls should be capped and sealed to minimize efflorescence and damaged caused by freeze/thaw cycles.

Fences with concrete block or brick pillars and PVC or vertical metal slats make attractive screen walls when screening large areas.

11.3.6.2.2.7 Equipment Screens

Careful attention must be given to fences intended to screen heating, ventilation, and air conditioning equipment. Provisions must be made to allow adequate airflow for proper operation of equipment and for sufficient maintenance space. Metal fencing around electrical equipment should be avoided if possible but, if used, must be bonded and grounded according to the National Electrical Safety Code and the National Electrical Code.

11.3.6.2.2.8 Earth Berms

Earth berms can be effectively used in place of conventional fencing. Berms are appropriate in high-visibility public areas with undesirable views to provide concealment where security is not a great concern. When used, earth berms must be appropriately landscaped, irrigated, (see Section 10 Landscaping) and maintained. Ensure that berms are not too large or too steep to mow. Establish maximum slope criteria.
