EXECUTIVE SUMMARY

Architectural Compatibility Standards - Seymour Johnson AFB, NC 1-1

1.0.0 Executive Summary

The primary purpose of the Seymour Johnson Architectural Compatibility Standards is to establish guidelines that 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 Architectural Compatibility Standards organizes the physical environment at Seymour Johnson into three visual areas: the Community Area, the Mission/Industrial Area, and the Family Housing Area. Each visual area is defined by current land use and by the proposed architectural theme and materials for the area. (Figure 1-1A)

The Community Area is the area along Wright Brothers Ave. from the main gate to Goodson Street, extending south to Blakeslee Avenue and east to Vermont Garrison Street. It contains the dormitories, community center, shopping, recreation, medical and worship facilities. For most visitors, it is the first impression they receive of the base.

Most of the buildings in this area are one or two-story masonry in various shades of red and brown brick. Some of the newer buildings have dark bronze sloped metal roofs; many of the older buildings have flat roofs with dark bronze trim.

Recent renovations in the Community Area have used materials that reinforce the theme of red brick and sloped dark bronze metal roofs.

The image for this area should be one of quality and permanence and emphasize the importance of the pedestrian. It should take on the characteristics of a campus environment through use of similar materials, well maintained grounds, walkways, and outdoor spaces. It is important to site buildings with the front facade to the main street and provide

The buildings shall be constructed of red brick with dark bronze sloped metal roofs. All buildings will be no more than two stories, except for dormitories, which may be three. Landscaping should complement a building’s function, reserving ornamental plantings for prominent buildings. It is also important to provide street trees along main roads and to screen obtrusive elements such as parking and transformers.

The Mission/Industrial Area comprises the largest land area on base. It surrounds the Community Area on the north, south and west. Facilities in this area range from small storage buildings (Figure 1- 2A) and operations buildings (Figure 1-2B), to administrative buildings, warehouses and hangars.

Many different materials were used to construct the existing facilities in the Mission/Industrial Area.

Metal wall and roof panels in beige and brown tones are the predominant materials for large warehouses and hangar buildings. Materials for other buildings include beige textured concrete masonry and exposed aggregate precast concrete panels. Existing roofs include flat roofs and sloped dark bronze metal roofs, some with large turned-down fascias. Visual unity can be enhanced by standardizing the palette of materials and colors.

Exterior walls of future buildings in the Mission/ Industrial Area will be constructed of textured concrete masonry units, similar in color to those used on the Air Force Reserves Recruiter (Figure 1-2C). Sloped roofs of dark bronze standing seam metal will be used to visually link the buildings to those of the adjacent Community Area. With the approval of the ACC Command Architect and the Base Civil Engineer, metal wall panels may be used on hangars and large industrial facilities. The color of metal wall panels will be beige to match Federal Standard 595b color #23617. All metal buildings will have a concrete masonry base with the height proportional to the size of the building, but not less than four feet high.

The Family Housing Area, located on the eastern side of the base, is adjacent to the Community Area and the main gate. Recent renovations have upgraded much of the housing with red brick, vinyl siding, and asphalt shingle roofs. This theme should continue throughout the zone. Non-housing facilities built within this area should be limited to two-story construction of red brick, with a dark bronze sloped metal roof. Landscaping should emphasize low maintenance, native plant materials.

INTRODUCTION

Architectural Compatibility Standards - Seymour Johnson AFB, NC 2-1

2.0.0 Introduction

2.1.0 Scope of the Document

The Architectural Compatibility Standards establishes guidance for design and construction at Seymour Johnson Air Force Base. Guidelines contained in the document are specifically designed to create a unified architectural character for the entire installation.

This document is intended for use by military, DoD civilian personnel, and private sector firms involved in all phases of facility planning, maintenance and repair, design, and construction. Base personnel should refer to this manual when planning or designing new buildings, additions, self-help work orders, or maintenance and repair work orders for existing buildings. Private sector firms contracted to provide professional architectural or engineering services should use the standards throughout the design process to produce work that blends and complements the environment at Seymour Johnson

AFB.

2.2.0 Review and Compliance

All projects, in-house work orders, and self-help work orders will include an architectural review by the Base Civil Engineer. Designers of self-help projects should meet with the Base Civil Engineering representative at the beginning of a project. All other projects will include an architectural review at the 35% preliminary design submittal. Proposed designs that do not comply with the Seymour Johnson Architectural Compatibility Standards require approval from the Base Civil Engineer.

Proposed designs that do not comply with the ACC Architectural and Interior Design Standards require a waiver from the ACC Command Architect (ACC/CEPT). If waiver is not granted, projects must be redesigned to comply. Requests for waivers must be submitted no later than the 35% Preliminary Design Submittal or prior to the start of self-help projects.

2-2A F-15E Static Display

2.3.0 Base Mission

The 4th Fighter Wing is host unit at Seymour Johnson AFB. The wing’s mission is to generate airpower, put bombs on target, and train F-15E aviators. The wing accomplishes its operational and training missions with the F-15E Strike Eagle aircraft. A dual-role fighter, the F-15E can fight its way to a target over long ranges, destroy enemy ground targets then fight its way out.

The 4th Fighter Wing is composed of four fighter squadrons, 333rd, 334th, 335th and 336th. Two of the wing’s squadrons are assigned the mission of training all F-15E aircrews for the Air Force. The other two are operational squadrons.

The 916th Air Refueling Wing, is an Air Force Reserve tanker unit located at Seymour Johnson AFB. The peacetime mission of the 916th ARW is to develop and maintain the operational capability of its subordinate units and to train reservists for worldwide duty. In the event of war or national emergency, the 916th ARW will fall under the direction of the Air Mobility Command, Scott AFB, Illinois.

The wing has 12 subordinate units, including the 916th Communications Flight, the 916th Medical Squadron and three groups of squadrons and flights: 916th Logistics Group, 916th Operations Group and 916th Support Group.

Architectural Compatibility Standards - Seymour Johnson AFB, NC 2-2

2.4.0 Regional Setting

2.4.1 Geography

Seymour Johnson Air Force Base occupies 3,233 acres (5 square miles) of land within the city limits of Goldsboro, North Carolina. It is approximately 50 miles southeast of Raleigh, on the Neuse River.

Highway 70 runs north of the base and Highway 117 lies to the west of the base. The current population of Goldsboro is about 48,000, and the population of surrounding Wayne County is approximately 110,000. Residential, agricultural, commercial, and industrial land uses occur adjacent to the installation.

2.4.2 Topography

Seymour Johnson is located on relatively flat land at the center of the coastal plain of eastern North Carolina, approximately 65 miles from the Atlantic Ocean. The topography includes the floodplain of the Neuse River, a higher terrace of the river, and a still higher terrace that may also be of riverine origin.

As in most Coastal Plain river valleys, the Neuse River valley is not symmetrical. The river flows along the south side of the watershed with the southern drainage divide located about four miles to the southwest. The northern divide lies many miles to the north. The south side of the valley, across the river from the base, is narrow with an abrupt, relatively steep slope to the uplands. The north side, where Seymour Johnson is located, rises very gradually, without a clear edge to the valley.

Elevations on the base vary from approximately 45 to 110 feet, gradually sloping downward from northeast to the southwest. The greatest relief is along Stoney Creek, where it flows through the higher terrace. Refer to the General Plan for flood zone information.

2-3A Regional Map

Architectural Compatibility Standards - Seymour Johnson AFB, NC 2-3

2.4.3 Soils

A soil survey of Wayne County indicates the presence of fifteen different soil series on base, reflecting the differing ages of the landscape and the variety of soil drainage created by the topography.

Geo-technical investigation is required for all subsurface design.

2.4.4 Climate

Eastern North Carolina has a temperate climate with long, humid summers and short, mild winters with frontal storm systems and cold spells. Precipitation averages 50 inches annually, with the greatest monthly rainfall occurring in the spring. Snow is infrequent.

Seymour Johnson’s location, near the Atlantic Coast, creates the potential for serious damage due to hurricanes and tropical storms. Hurricane season runs from June to November.

• Latitude = 35°20’ North

• Longitude = 77°50’ West

• Altitude above Sea Level = 100 feet

• Winter outdoor design temperature = 22°

• Heating degree days = 3191 (based on 65°)

• Sun altitude angle: Noon on Dec. 21 = 31° Noon on June 21 = 77°

• USDA Plant Hardiness Zone 8

2-4A Solar Altitude Angles

2.4.5 Response to Climate

In Seymour Johnson’s humid southern climate, a primary design objective is to minimize summer solar gain. In winter, heat loss should be minimized and solar gain should 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.

Another effective strategy for roof space ventilation is the use of ridge vents. Thermally massive envelope materials, such as masonry walls, 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.

ARCHITECTURAL CHARACTER

Architectural Compatibility Standards - Seymour Johnson AFB, NC 3-1

3.0.0 Architectural Character

3.1.0 Goals

The design guidelines in this document have been developed in response to four principal goals:

• Create buildings which project a corporate image for the Air Force

• Develop a campus atmosphere at Seymour Johnson

• Establish a style which responds to the architectural context of the region

• Create architectural standards that are compatible with the existing built and natural environment

3.1.1 Creation of a Corporate Image

“Corporate image” can be interpreted in a variety of ways. The design guidelines have been formulated to express an architectural character that projects an image of efficiency and permanence. Common building forms and materials will allow individual buildings to appear as part of a larger whole.

Logical vehicular circulation and an emphasis on creating highly visible building entrances will help develop the image of buildings within a corporate office park.

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

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

Carefully designed landscaping is one of the most effective means of achieving visual harmony on a basewide scale. A base street tree program can mitigate the negative impact of older, incompatible buildings. Landscape guidelines that encourage use of a limited number of regionally suitable species will help unify the entire base.

3-1A Base Main Entrance Sign

Architectural Compatibility Standards - Seymour Johnson AFB, NC 3-2

3.1.2 Development of a Campus Atmosphere

Focus on the pedestrian is key to the creation of a campus environment. The 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. A carefully designed network of paths connecting living, working, shopping and recreational facilities will increase pedestrian activity and help to overcome the perception that “it’s too far to walk.”

Successful campus buildings have clearly defined entrances and often include arcades and courtyards that provide gathering places for recreation and socializing. These features are encouraged. The recommended building materials and fenestration patterns are designed to provide human scale on all buildings, another feature common to successful campus architecture.

3.1.3 Response to Regional Architecture

Since the 18th century, settlers in eastern North Carolina have adapted buildings to the local climate of hot, humid summers and temperate winters by incorporating moderately pitched roofs and large deep porches to provide protection from the summer sun. Buildings were constructed of locally harvested woods and brick made from local clays.

As in the other original colonies, early roofing materials were wood shingles; as technology developed, many structures incorporated metal roofing (Figure 3-2B).

Many of the design concepts of colonial architecture are still important today. Thick masonry walls help keep dwellings cool in summer by slowing heat transfer, and operable windows can be used to provide natural ventilation. One and two-story buildings with sloping metal roofs, entrance porches, and walls of locally manufactured masonry continue the tradition of an architectural style which developed in response to the local environment.

3.1.4 Integration of new architectural

standards with existing conditions

The Seymour Johnson Architectural Compatibility Standards have been developed acknowledging that most facilities on base will remain in use for many years. A major objective of the document is to establish guidelines that allow new facilities, additions, and renovations to existing buildings to be visually compatible.

In the past, base leadership has followed a plan to use red brick and dark bronze metal roofs on dormitories, community buildings, and other facilities in the central part of the base (Figure 3- 3A). A Community Center Plan has been created by the Harris Group, Reston, VA, to guide future development in this area. The Architectural Compatibility Standards supports this vision of the Community Area.

A wider variety of architectural styles and building materials are found on existing facilities in the Mission/Industrial area surrounding the Community Area. To achieve architectural compatibility in this zone, the development guidelines will limit material choices. Future materials will harmonize with the prevailing beige and brown color scheme, and will be selected based on durability, economy, and aesthetic aspects.

3-3A Renovated dormitories and many other facilities in the Community Area make use of red brick walls and dark bronze metal roofing.

3-3B Constructed of beige split-face concrete masonry with dark bronze metal roof, the 916th Wing Headquarters is an example of compatible development in the Mission/Industrial area.

COMMUNITY AREA

Architectural Compatibility Standards - Seymour Johnson AFB, NC 4-2

4.1.0 Community Area

The Community Area comprises the main cantonment area of the base. Nearly all of the functions of a small city are represented in this zone, including living, working, recreation, medical, shopping, and worship facilities. It is the most public-oriented area and the first image of the base for most visitors.

The majority of the buildings in this zone are one and two-story masonry in various shades of red and brown brick. Other existing materials include light colored concrete masonry, and metal panel siding.

Newer buildings have dark bronze sloped metal roofs. Many of the older buildings have flat roofs with either a small fascia or a larger turned down fascia in dark brown tones. There has been a recent effort to renovate and construct buildings using red brick and sloped standing seam metal roofs in dark brown shades.

MISSION/INDUSTRIAL

Architectural Compatibility Standards - Seymour Johnson AFB, NC 4-5

4.3.0 Mission/Industrial Area

The Mission/Industrial Area surrounds the Community Area on three sides. It includes facilities that are dedicated to the mission of the base: aircraft runway and flight line activities, squadron buildings, munitions facilities, small arms range, maintenance facilities, industrial and storage buildings, and the 916th Air Refueling Wing complex.

Existing structures range in size from small storage buildings to large warehouses and hangars. Most of the larger buildings have metal wall and roof panels in beige and brown tones. The remainder of the buildings are predominantly light colored concrete masonry, including ribbed and split face units, and painted concrete masonry. Some of the small storage buildings and a few of the operations buildings are constructed of light colored exposed aggregate precast concrete panels. Existing roofs include flat roofs and sloped dark brown metal roofs, some with a large turned down fascia.

A renovation to the 916th Fuel Shop has added one-story concrete masonry wings to the large metal building, giving the large structure a more human scale. The split face block visually integrates the building with adjacent facilities and provides a durable finish at ground level (Figure 4-5C).

Located within this zone is a minimum-security federal prison camp that leases the land from the base. Completed in 1991, the compound’s buildings are light-colored exterior insulation and finish system with sloped metal roofs that blend in well with the surrounding architecture of the base.

More than 500 inmates supplement the work force for the base, helping to maintain the grounds and facilities.

FAMILY HOUSING

Architectural Compatibility Standards - Seymour Johnson AFB, NC 4-7

4.5.0 Family Housing Area

The Family Housing Area is located on the eastern side of the base, adjacent to the Community Area and the main gate. It is composed almost entirely of accompanied housing. Recent renovations have improved both the architecture and the landscaping in this area. Most units are red brick with gently sloping asphalt shingle roofs (Figure 4-7A, 4-7B, 4-7C).

Military Family Housing is subdivided into three areas on base: Wayne Manor, Berkeley Village, and the Mobile Home Park. Wayne Manor and Berkeley Village total 1,698 units, including 154 units for officers and 1,544 for enlisted. There are 45 pads for privately-owned trailers in the Mobile Home Park.

The location is very convenient to the amenities of the Community Area. The base exchange, commissary, chapel, housing office, youth center, child development center, and hospital are located off Vermont Garrison Street, which separates the Family Housing Area from the Community Area.

The theater, bowling alley, convenience stores, and athletic fields are located just a few blocks away from Vermont Garrison Street. The golf course separates the housing from the industrial area and the flight line.
