Executive Summary

Design Compatibility Guidelines - Barksdale AFB, LA 1-1

The primary purpose of the Barksdale Design Compatibility Guidelines is to establish guidelines which will create a unified visual character for the entire installation. Architectural compatibility focuses on harmony of all of the components that shape the appearance of the base. This includes, but is not limited to, building form, color and type of materials, landscaping, site furnishings, site design, and signage.

The Barksdale Design Compatibility Guidelines organizes the physical environment at Barksdale into five visual areas: the Historic District, Community Area, 917th Wing, Leadership Training/Weapons Storage Area, and the East Reservation (Figure 1-1B). Each visual area is defined by current land use and by the proposed architectural theme and materials for the area (Figure 1- 2A).

The design guidelines for facilities are strongly influenced by the historically significant structures and site planning at Barksdale. The Historic District with its radial beaux-arts plan and French Colonial Revival buildings is a strong influence on the architecture of the rest of the base. To coordinate with recommendations of the State Historic Preservation Office (SHPO), new facilities in the Historic District will be compatible with, yet discernible from existing historic buildings. Exterior insulation and finish systems may be used in the historic district to achieve compatibility with existing stucco materials. More economical standing seam metal roofing in red color can used to achieve compatibility with the existing clay tile roofs.

In visual areas outside the Historic District, red standing seam metal roofs and sloped roof forms will visually link buildings with those of the Historic District. Use of brick exterior walls in buff color will differentiate newer buildings from historic structures and will provide a durable low maintenance exterior finish. Porches, arcades, and colonnades will be integrated into building designs to provide shade and reflect the influence of local architecture.

2.1 Scope of the Document

The Barksdale Design Compatibility Guidelines document establishes criteria for design of the site and built environment at Barksdale Air Force Base.

It is intended for use by personnel involved in all phases of Base planning and design. Base personnel should refer to this manual when:

● Designing new projects.

● Designing additions or renovations.

● Providing maintenance and repair.

Private sector firms contracted to provide professional architectural or engineering services should become familiar with the guidelines prior to the start of a project.

2.2 Project Review Requirements

● All projects, in-house work orders, and self-help work orders will include an architectural review by the Base Civil Engineer (BCE).

● Designers of self-help projects must meet with Base Civil Engineering at the beginning of a project.

● All other projects will include an architectural review at the 35% preliminary design submittal.

● All exterior changes in the Historical District shall require a BCE Engineering Flight review to meet SHPO requirements.

● Prior to construction, Permits (Construction Work, Digging, etc.) for must be completed by the Urban Forester along with the Project Manager and the Construction Supervisor.

● A geotechnical report including soil borings and design recommendations by a qualified geotechnical engineer is required for all building foundation and subsurface designs.

● Development in wetland areas will comply with all applicable state and federal regulations.

Wetland development currently requires additional permitting by the Army Corps of Engineers. Coordinate additional permit requirements with the Base Environmental Engineering Department.

2.5 Regional Setting

Geography

Barksdale Air Force Base encompasses 21,802 acres (34 square miles) of land in the Shreveport-Bossier City metropolitan area of northwest Louisiana.

Current population of the area exceeds 390,000 according to the 2000 US Census Population Estimate. Interstate I-20 parallels the base boundary on the north; Louisiana Highway 71 and the Red River lie to the west. Residential, agricultural, industrial and commercial land uses occur adjacent to the installation.

The cantonment, airfield and munitions storage areas are located on the westernmost 5,120 acres.

With the exception of the family housing area and isolated industrial uses, the 16,682 acre eastern portion of the base is largely wooded and undeveloped.

Topography

Barksdale AFB is located on relatively flat land in the Western Gulf Coastal Plain. Approximate elevations range from 360 feet above sea level in the north-western part of the base, to 135 feet in the southwest near Mack’s Bayou and Flat River.

Facilities must be constructed on terrain above the 100-year flood plain elevation of 160 feet above mean sea level. Refer to the General Plan for flood plain locations.

The Base has approximately 770 acres of lakes, rivers, bayous, and 1,500 acres of wetlands. These natural resources harbor wildlife, provide outdoor recreational opportunities, and regulate stormwater runoff.

Soils

Local soils are composed of alluvial deposits of clay, silt, and sand. Bearing capacity varies, and water table elevation is often high. A geotechnical report including soil borings and design recommendations by a qualified geotechnical engineer is required for all building foundation and subsurface designs.

2-3A Regional Location

Louisiana

Introduction SECTION 2.0

Design Compatibility Guidelines - Barksdale AFB, LA 2-4

Climate

Northwest Louisiana has a humid temperate climate with hot, humid summers and mild winters.

Barksdale AFB has a monthly average high temperature of 55°F in January and 93°F in July (source: www.wunderground.com). Rainfall averages

46.6 inches annually, with the greatest monthly rainfall occurring in spring. Hurricanes and tropical storms are uncommon, but short periods of heavy rainfall can occur throughout the year. Snow is infrequent, averaging 2 inches per year. Prevailing winds are from the south.

• Latitude = 32.27°N Longitude = 93.36°W

• Winter outdoor design temperature = 25°F

• Heating degree days = 2,337 (based on 65°)

• Sun altitude angle: Noon on Dec. 21 = 34.25° Noon on June 21 = 81.15°

• USDA Plant Hardiness Zone 8

Response to Climate

In Barksdale’s humid southern climate, a primary design objective is to minimize summer solar gain.

In winter, heat loss should be minimized and solar gain can be used to advantage.

Design strategies include shading building walls and roofs with deciduous trees on south, east and west sides, providing ample roof and crawl space ventilation, and orienting the building to benefit from summer breezes. Thermally massive envelope materials, such as masonry walls and clay tile roofing, may be used to reduce peak air conditioning loads by delaying peak heat gain.

Building openings should be protected from summer sun by using a combination of high performance glazing and traditional southern methods of porches, roof overhangs, and colonnades. Wall assemblies should be insulated to provide a minimum R-value of 19. Roof assemblies should have a minimum R-value of 30.

SECTION 3.0

Architectural Character

Design Compatibility Guidelines - Barksdale AFB, LA 3-1

The Barksdale Design Compatibility Guidelines in this document have been formulated in response to three principal goals:

• Design facilities that are compatible with Barksdale’s architectural heritage.

• Maintain the campus atmosphere on base.

• Ensure buildings project a corporate image for the Air Force.

3.1 Design facilities that are compatible with

Barksdale’s architectural heritage The Barksdale historic district with its radial beaux-arts plan and French Colonial Revival buildings is a significant cultural resource that has served the functional needs of the base for over 70 years.

Planning and design of Barksdale Airfield began in 1931 under the supervision of architect Capt.

George E. Lamb. Landscape design by Capt.

Norfleet Bone and Hugh K. Harris followed. The airfield, hangars for 100 aircraft, barracks for 1,500 men, administrative and support buildings, and approximately 200 officers and NCO quarters (referred to as “appropriated housing”) were constructed from 1931 to 1938. Almost all of the original structures remain, although most non-housing buildings have changed function and received varying degrees of modification to accommodate modern mission demands.

Housing

The historic district was listed on the National Register of Historic Places in 1994. Defining features of the existing appropriated housing buildings include concrete piers with concrete stem walls, wood beams and wood flooring, terra cotta block bearing walls with stucco finish, steeply pitched hip roofs with dormers and flat clay tile roofing, copper gutters and downspouts, and the use of cast concrete, wrought iron and painted wood trim. Individual units are painted in one of five exterior color schemes. This concept creates visual harmony without causing monotony.

3-1B The Visiting Officers Quarters reinterprets historic design elements.

3-1C One of the original houses in the Historic District.

Architectural Character SECTION 3.0

Design Compatibility Guidelines - Barksdale AFB, LA 3-2

Administration

Larger administrative buildings, many of which were former barracks, are sited adjacent to the appropriated housing area. Most of the buildings have full basements with a concrete foundation system, reinforced concrete post and beam construction with concrete floors, and terra cotta infill walls with stucco finish. The roofs have a shallower pitch and pedimented gable ends. These buildings usually have simple symmetrical massing with a tripartite facade organization accentuated by painting base and trim a contrasting dark brown color. Common detailing includes stucco quoins, projected bands at floor levels, and elaborate cut stone entrance portals.

Hangars

Historic hangars are enclosed with divided-light glass curtainwalls between large corner piers of stuccoed terra cotta block. End elevations often have stuccoed parapets above divided-light sliding doors. Long-span trusses frame a variety of barrel, pitched and flat roofs.

3.2 Urban Planning

The historic district is further defined by its formal circulation plan. Detached communal garages and alleys in the appropriated housing area are combined with large shade trees to form a unique streetscape. Consistent setbacks, simple building massing and live oaks planted along major avenues allow streets in the administrative areas to become urban spaces.

To architectural historians, the Barksdale historic district is important because it is a well preserved example of the largest collection of French Colonial architecture in Louisiana. It is most significant to the Air Force because it is an outstanding example of base planning and design that continues to have a positive impact on the people who live and work within it.

3-2A Many former barracks were converted into administrative buildings.

SECTION 3.0 Architectural Character

Design Compatibility Guidelines - Barksdale AFB, LA 3-3

Future development guidelines must ensure compatibility with Barksdale’s wealth of fine architecture. The design guidelines in this document challenge architects to create new facilities by using traditional design concepts, while avoiding strict imitation of the historic structures.

New buildings should be compatible with, yet discernible from facilities in the historic district.

3.3 Maintain the Campus Atmosphere

Focus on the pedestrian is the key to the creation of a campus environment. These design guidelines propose methods for mitigating the negative impact of the automobile by separating parking from building entrances and linking buildings with shaded pedestrian paths. The relocation of the gymnasium to the community center/dorm area can be used as a catalyst to improve the pedestrian circulation in this area. Additional shaded paths would increase pedestrian activity and help to overcome the perception that "it's too far to walk."

Campus buildings have clearly defined entrances and often include porticos and colonnades that act as a transition from building to site. These features are encouraged. The recommended building materials and fenestration patterns are designed to provide human scale on all buildings.

Landscaping with low maintenance, indigenous plant materials is an effective method of providing shaded pedestrian paths. Landscape guidelines requiring the use of a limited number of species will help unify the entire base.

3-3A Pedestrian paths link living quarters with recreational and administrative areas.

3-3B The Barksdale Inn’s well-defined entrance, decorative porches, and effective landscaping contribute to the campus atmosphere.

Architectural Character SECTION 3.0

Design Compatibility Guidelines - Barksdale AFB, LA 3-4

3.4 Ensure buildings project a corporate image for

the Air Force

"Corporate image" can be interpreted in a variety of ways. These design guidelines have been formulated to express an architectural character that projects an image of quality and permanence.

Common building forms and materials allow individual buildings to function as part of a larger whole.

The combination of background buildings and high profile object buildings work together to form an urban fabric. The unifying appearance of background buildings allows high profile buildings, such as headquarters or the chapel, to be focal points. Logical vehicular circulation and an emphasis on creating highly visible building entrances will further develop a unified, corporate image for base facilities.

"Corporate image" includes worker satisfaction as a priority. These design guidelines contain provisions for operable windows in all offices and living areas.

The addition of site lighting, site furnishings and shaded outdoor lunch areas will also benefit building occupants.

3-4A Distinctive building forms, site features, and landscaping create a unique character that unifies the appearance of the base.

SECTION 4.0

Visual Areas

Design Compatibility Guidelines - Barksdale AFB, LA 4-1

The Barksdale Design Compatibility Guidelines organizes the physical environment of the base into five visual zones:

● Historic District (Housing, Non-Housing, Flightline)

● Community Area

● 917th Wing

● Leadership Training/Weapons Storage Area

● East Reservation (Housing, Non-Housing)

A fundamental purpose of this document is to provide a unified architectural character for the entire installation. Design recommendations for each zone are coordinated to allow site and facilities to harmonize with the immediate surroundings, as well as support the overall design goals for the base.

4.1 Historic District

The Historic District comprises the core of the base.

It includes all of the existing structures listed on the National Register. The boundaries are roughly parallel to the Historic District Management Boundary established in the USACERL SR95 report, with the addition of the golf course area.

A variety of functions coexist in this zone including:

single family housing and duplex units, temporary lodging, dining, recreation, worship, administration, aircraft hangars and support buildings. It is a public-oriented zone and the first image of the base for visitors by car or by aircraft.

SECTION 4.0 Visual Areas

Design Compatibility Guidelines - Barksdale AFB, LA 4-3

Design all facilities to be compatible with historic buildings. Existing non-compatible buildings built in the 1950’s through 1970’s should be demolished or renovated to meet the new guidelines as funding becomes available.

The Historic Visual Area has three subzones:

Housing, Non-Housing, and Flight Line. The guidelines on the following pages are for all subzones except where noted.

Site Planning

• Focus on pedestrian circulation.

• New buildings must address streets, using same setbacks as adjacent historic structures.

• Parking should be located to the side or behind buildings.

• Parking should not be located between the building and principal street, unless properly landscaped and with the approval of ACC.

• Maintain existing open spaces within the housing area (Appropriated Housing).

4-3A The entrance boulevard is the heart of the historic district.

Design Compatibility Guidelines - Barksdale AFB, LA 4-4

Building Form

• Maximum height for all buildings, except dormitories, is two stories. Dormitories may be three stories.

• Simple massing is recommended (Non-Housing and Flight Line).

• Building entrances should be easily visible from the street and parking areas.

• Locate the main entrance of the building on the principal street.

• Porticos, arcades and colonnades can be used to transition from the building to the site, and recall traditional character without directly repeating features found on historical buildings.

• Use the traditional design concepts of balance, proportion, and tripartite (base-middle-top) facade organization to create compatibility without the use of stylistic imitation.

• Locate maintenance and trash services in less visible areas, to the rear or side of the building.

• Clustering of buildings to create courtyards and similar outdoor spaces is encouraged (Non- Housing and Flight Line).

Design Compatibility Guidelines - Barksdale AFB, LA 4-5

Roofs

• Clay tile, concrete tile, or laminated asphalt shingle roofs in hip or gable configuration with minimum 8:12 pitch. Asphalt shingles should have a minimum 30-year warranty. Color to be closest manufacturer match to Colonial Red (Federal Standard 595B_30109) (Appropriated Housing).

• Clay tile, concrete tile, or standing seam metal roofs in hip or gable configuration with minimum 4:12 pitch. Color to be closest manufacturer match to Colonial Red (Federal Standard 595B_30109) (Non-Housing).

• Metal roofs with minimum 4:12 pitch, color to be closest manufacturer match to Colonial Red (Federal Standard 595B_30109). Color of hangar roofs along the flight line to be light warm gray (closest manufacturer match to Federal Standard 595B_27875) (Flight Line).

• Exception: When roofs become too large to accommodate a 4:12 pitch; the ACC standard of 3:12 can be used with an approved waiver.

Larger buildings may have minimum 1:12 roof pitch with Base Civil Engineer and ACC approval.

Exterior Walls

• Stucco or EIFS. Colors shall comply with one of the five existing color schemes (Appropriated Housing). See Appendix A.

• Stucco or EIFS (Non-Housing and Flight Line).

Trim

• Stucco, EIFS, pre-finished metal, metal clad wood, or cast stone in off-white, beige or brown tones depending upon location and size to match Base limestone tones (Non-Housing and Flight Line).

• Painted wood trim may be used in the appropriated housing only (Appropriated Housing).

• Small accent bands may be in medium to dark tones (Appropriated Housing).

• All trim details to be submitted to Base Civil Engineer for review.

Design Compatibility Guidelines - Barksdale AFB, LA 4-6

Doors and Windows

• Windows shall be prefinished aluminum with high performance, non-reflective glazing such as low emissivity coating or argon filled.

Window units shall be thermally broken

• Provide operable windows in housing, educational, and administrative spaces.

• Aluminum storefront and windows should be dark bronze anodized or have fluoropolymer coating in dark brown color (Non-Housing and Flight Line).

• Aluminum windows in housing shall be white (Appropriated Housing).

Detailing

• Literal imitation of “signature” historic details such as quoins, classical window surrounds, false dormers, and windows or louvers in pediments is prohibited by state regulations for historic districts.

• Reinterpreting historic details in an alternate material or creating restrained abstractions of historic details is an effective means of achieving compatibility, while still being able to differentiate new from historical details.

Site Furnishings

• Trash dumpsters and service area screen walls should be the same material as adjacent structures.

• Small storage buildings should use existing garage buildings as a prototype with regard to roof slope and form, roof and wall materials, and color of materials (Figure 4-7A).

• The style of the site furnishings should be consistent and reflect the historic character of this visual area. The existing site furnishings should continue to be used in this visual area (Figure 4-7B).

• Final selection of site furnishings (i.e., benches, lighting fixtures, tables, bollards, trash receptacles) are to be submitted to Base CE, Engineering Flight, Architect's Office for approval, prior to procurement.

Design Compatibility Guidelines - Barksdale AFB, LA 4-8

Landscaping

• Plantings in this visual zone will reinforce aesthetic of the radial beaux-arts site plan by having a more formal (not necessarily symmetrical) arrangement.

• The mature live oaks and other mature hardwoods in this area are a significant asset to the Base. Special care, protection, and in some cases re-planting, needs to be implemented in order to maintain the aesthetic beauty of the district, especially the street trees along major roadways.

• This is a prominent visual area; the landscape in this area should be more ornamental and groomed then the rest of the base.

4-8A Live Oaks are a typical tree used for streetscapes.

Design Compatibility Guidelines - Barksdale AFB, LA 4-9

4.2 Community Area

The Community Area is bordered by the historic district on the north, the base fence line on the south and west, and the runway to the east. Community functions including the Commissary, Base Exchange, childcare, education and recreation facilities share the zone with enlisted dormitories.

This mix of functions occurs in a relatively compact area.

Development of the area began in the 1950’s. Most contemporary structures are one story with flat roofs and buff brick walls. New dormitories are constructed of EIFS walls with red tile mansard roofs. Older buildings are painted concrete masonry. The new dormitories and the Housing Maintenance Facility are good examples for compatible development in this zone.

Design Compatibility Guidelines - Barksdale AFB, LA 4-10

• Focus on pedestrian circulation and siting buildings to create outdoor spaces.

• Where large parking lots are required, integrate safe pedestrian paths, and break parking into smaller landscaped areas.

• Simple massing is recommended.

• Porticos, arcades and colonnades can be used to transition building to site, and recall the traditional character without repeating features found on historical buildings.

• Traditional design concepts of balance, proportion, and tripartite facade organization will create compatibility without the use of stylistic imitation.

• Standing seam metal pitched roofs with minimum 4:12 roof pitch. Provide metal roofs with a Fluoropolymer (e.g. Kynar 500) factory finish; 20-year warranty.

• Exception: When roofs become too large to accommodate a 4:12 pitch; the ACC standard of 3:12 can be used with an approved waiver.

Larger buildings may have minimum 1:12 roof pitch, with Base Civil Engineer and ACC approval.

Design Compatibility Guidelines - Barksdale AFB, LA 4-11

• For facilities adjacent to Historic District: walls will be stucco in color “Barksdale Buff” (Federal Standard 595B_ 33690).

• For facilities not adjacent to Historic District:

walls may be stucco in color “Barksdale Buff” (Federal Standard 595B_ 33690), or in an approved shade of brick.

Trim

• Trim may be stucco, EIFS or pre-finished metal in color “Barksdale Buff” (Federal Standard 595B_ 33690), or “Barksdale Brown” (Federal Standard 595B_ 20117).

• Cast stone shall match Base limestone tones.

Doors and Windows

• Prefinished aluminum windows, with high performance, non-reflective glazing such as low emissivity coating or argon filled, in solar bronze tint. Window units shall be thermally broken

• Provide operable windows in housing, educational, and administrative spaces.

• Aluminum storefront and windows should be dark bronze anodized or have fluoropolymer coating in “Barksdale Brown” (Federal Standard 595B_20117).

Detailing

• Literal imitation of historic details is not allowed.

• Re-interpreting historic details in an alternate material or creating restrained abstractions of signature type details is an effective means of achieving compatibility, while still being able to differentiate new from historical details. For example, quoins, projected courses and special sill and water table shapes can be detailed in brick. Stucco or EIFS quoins can be abstracted (Figure 4-11C).

Design Compatibility Guidelines - Barksdale AFB, LA 4-12

• Trash dumpsters and service area screen walls should be the same material as adjacent structures.

• The site furnishings in this are should complement the larger scaled contemporary structures located within the visual area (Figures 4-12A, 4-12B, and 4-12C).

• The use of concrete benches and aggregate faced site trashed receptacles should be reserved for very utilitarian areas within this zone.

• Final selection of site furnishings (i.e., benches, lighting fixtures, tables, bollards, trash receptacles) are to be submitted to Base CE,

• This overall plan of this visual zone is a number of smaller unrelated site designs that are tied together by the circulation system.

Landscaping, in particular, streetscaping can help unify this visual zone.

• Landscape designs in this visual zone can utilize a more informal, casual arrangement of the plantings.

Guidelines: Architectural

Design Compatibility Guidelines - Barksdale AFB, LA 5-1

5.1 Architectural Review

• Each facility design project will include a design review by the BCE, Engineering Flight, Architect's Office, as part of the 35% Preliminary Design Submittal review process.

• The cover letter accompanying the submittal must identify any items that do not comply with the requirements of this guide.

• Self-help Projects: Designers of self-help projects should schedule a meeting with the BCE, Engineering Flight, Architect's Office to discuss requirements prior to the start of a project.

5.2 Additions

• In conformance with ACC policy, when the floor area of an addition is less than 25% of the existing building floor area, the addition should be designed to match the existing building, unless otherwise instructed by the Base Civil Engineer.

• Exception: In all zones except for the Historic District, where a high maintenance existing finish such as paint occurs, provide a low maintenance material that does not require painting and that meets the guidelines for the zone.

• When the floor area of the addition is equal to 25% or more of the existing building floor area, the addition and the original building are required to comply with the architectural compatibility guidelines for new buildings.

• Whether large or small, additions should not appear as obvious add-ons. Match form, massing and scale to make the addition and the original structure appear as parts of a new, unified whole.

• Exception: To comply with State Historic Preservation Office recommendations, additions to historic structures should be compatible with but discernable from the original building.

BCE, Engineering Flight, Architect's Office and Environmental Flight, Historical Resources Manager shall review all changes for compliance w/ SHPO requirements.

• Facility design shall incorporate energy-efficient siting and should be compatible with the existing natural environment.

• Refer to the Barksdale General Plan for regulations on noise reduction, particularly in areas surrounding the flight line.

Site Development Pattern

• Arrange buildings in tight groupings, which share parking and encourage people to walk between buildings (Figure 5-3A).

• Where possible, integrate new buildings into existing groupings.

• Areas between buildings should be designed as exterior pedestrian spaces.

• Use building forms, landscaping, and existing topography and wooded edges to enclose outdoor spaces.

• Configure site to separate service zones from parking and pedestrian spaces. Screen service areas from major streets.

• Comply with the latest edition of UFC 4-010-01 DoD Minimum Antiterrorism Standards for Buildings.

Environmental Stewardship

• Site planning should minimize the negative impact on the natural environment.

• Design facilities to work within the existing topography; preserve as many large trees as possible.

• In undeveloped forest areas, configure the site layout to retain large parcels of wooded habitat.

• Avoid development in the wetlands (Figure 5- 2B). Refer to the General Plan for wetland locations.

5-2A The arrangement of buildings in the Historic District permits unobstructed views of front facades from primary streets.
