LANDSCAPE STANDARDS APPLICATION MATRIX
This vision requires a “structure” which the landscape standards will provide. Ultimately, the vision is achieved over time as project after project continues to connect the campus landscape through the use of these common standards.
APPLYING THE STANDARDS Certain standards are appropriate for use across the entire Auburn University campus. However, other standards will not be appropriate for use in every application. Across the campus, landscape types vary greatly in terms of function, visibility, scale and utilization. Therefore, the list of landscape standards offers a range of treatments as varied as the landscape itself, but which combine to achieve a unified campus language. In section 3, the landscape use zone framework is introduced. This framework divides the campus landscape into landscape use zones based on the proposed land use map found in the Comprehensive Campus Master Plan Update 2013. These landscape use zones will also provide the framework by which landscape standards shall be applied across campus - connecting appropriate materiality and aesthetics to each site. The application matrix in Table 4-1 connects each landscape standard with the landscape use zone(s) in which they can be utilized. Landscape standards appropriate for use campus-wide are highlighted in orange. As part of any future project on campus, the design team will utilize the design review checklist (see appendix 1) to verify that the appropriate standards have been assigned to their site. Following the matrix, is detailed information for each landscape standard. Standards which apply to the campus as a whole are marked with the label.

“The Vision for the Auburn University landscape is to provide a structure which will shape a beautiful, memorable and enduring pedestrian oriented campus while reintegrating cultural and natural systems through constructed urban ecologies and restored and revitalized ecosystems.”
CAMPUS LANDSCAPE ZONE:
The Campus Landscape Master Plan identifies a series of standards which shall be utilized on all future construction and renovation work which takes place across the Auburn University campus. These guidelines in practice will promote a unified campus language that reinforces the landscape vision for Auburn University as defined in section 3:

SURFACE PARKING AND ROADWAY STANDARDS At the end of this section, you will find guidance which applies uniquely to the surface parking and streetscape landscape zone. This landscape zone, while it requires the application of many of the landscape standards as shown in Table 4-1, requires an additional set of rules which are specific to parking lot and streetscape settings. This section of guidance will inform parking lot design, streetscape design standards, bicycle network decisions and gateway locations.

A. When it is determined to be dead; or
campus-wide standard TREE PRESERVATION The Auburn University Tree Preservation Policy, as adopted March 26, 1990 and reaffirmed June 19, 2009, shall be followed during all maintenance and construction activities. The policy reads as follows:
B. When it is determined to be diseased beyond preservation, as evidenced by the lack of healthy, living foliage during the normal growing season; or
“Auburn Univesity recognizes that trees located on its campuses are valuable natural resources. Trees are important for the protection of the environment, for the maintenace of the quality of life, and for added appearance of the campuses. Because of Auburn’s land-grant traditions and expertise in the fields of forestry and agriculture, it is essential that the University exert leadership by example in its efforts to preserve and renew these assets. The Board of Trustees shall direct the development and adoption of a master landscaping plan for each campus which shall show the location, species, and size of existing trees and of new trees to be planted. The Board further directs the establishment of a budget and the solicitation of gifts and memorials to fund this policy. Since the trees are a living and growing resource that appreciate over a long growth process and which have an indeterminate life span, Auburn University does hereby establish these tenets for their protection, preservation and renewal: I. Trees will be maintained, preserved and protected at all times; II. Trees will be considered for removal under certain circumstances here inafter set out; III. Trees may be removed only after following the procedures hereinafter established; and IV. Trees that are removed shall be replaced where feasible. I. Trees will be maintained, preserved and protected A. Every effort shall be made to maintain, preserve, and protect trees and to keep them pruned, stabilized, and free from damages from the elements and disease.
C. When its location, condition, or deterioration constitutes a safety hazard; or D. When its location affects the preservation and maintenance of adjacent buildings and unduly contributes to the deterioration of the building; or E. When the tree is damaged from the elements or disease to the extent that its appearance is unduly affected; or F. When its location is determined to be an obstruction and a hazard to utility lines; G. When its location interferes with the construction of facilities and their site development; or H. For any other appropriate reason. I. The identification of the tree meeting the above circumstances shall be the respossibility of the Superintendent of the Grounds Department at each campus. III. Tree Removal Procedure A. The Superintendent of the Grounds Department shall submit a written recommendation for the removal of a tree to the Assistant Vice President of Facilities at the Auburn University campus, or to the Director of Physical Plant at Auburn University at Montgomery campus, who shall approve or disapprove the recommendation. B. The recommendation shall identify the location, species, and reason for removal. C. The recommendation shall also indicate whether a replacement tree should be planted, giving the location and species, or the reason if the planting of a replacement tree is not recommended. D. Approved recommendations for removal shall be submitted to a TREE PRESERVATION COMMITTEE for each campus, which shall consist of three (3) persons appointed by the President of Auburn University for the Auburn campus and the Chancellor of Auburn University Montgomery for the Montgomery campus.
B. Every effort shall be made to limit the removal of trees on construction sites for new and expanded buildings, roadsm and utilities.
E. The committee shall conduct timely review of the recommendation for tree removal and replacement and in the interest of time, may conduct a telephone conference call meeting.
C. The University Architect shall work with project architects, engineers and landscape architects to limit tree removal through appropriate site development.
F. Majority approval, in writing, of the Committee is required to permit removal.
D. All construction plans and specifications shall require the identification of the trees to be protected, the construction of protective barriers around protected trees which shall be maintained during the construction, and substantial monetary penalties for the destruction and damage to such protected trees. E. No trees shall be removed without adherence to the tree removal policy set out herein. II. A tree may be considered for removal under the following circumstances
Figure 4-1. Trenching (left) completely cuts off entire portions of a trees root sytem. Tunneling (right) reduces the amount of damage to the tree’s root system as compared to trenching
Figure 4-2. Tree Protection Fence Detail w/ Critical Root Zone
G. The President of Auburn University may overrule the recommendation of the committee.
A. When it is necessary to remove a tree, it shall be the policy to plant a replacement tree.
H. It is recognized that there may be exceptions to this Policy, as follows:
B. The loccation and species of the replacement tree shall be consistent with the master landscaping plan for each campus.
1. Emergencies where safety and preservation of facilities require immediate removal. 2. Replacement of newly planted trees which do not survive. Replacement will be made with similar species, size and shape. 3. Reports of removals under these exceptions shall be made to the TREE PRESERVATION COMMITTEE of the appropriate campus.
C. Particular care shall be taken to avoid the planting of trees that would interfere with the Master Campus Plan, futue designated building sites, current and projected utility locations, and projected street developments.” See Figures 4-1 and 4-2 for typical tree preservation techniques that should be utilized on campus during all maintenance and construction activities.

Auburn University Landscape Master Plan, Comprehensive Campus Master Plan Update 2014
campus-wide standard HERITAGE TREES The following guidelines shall be assessed during the determination of whether or not a tree shall qualify for the “Heritage” designation:
Size and/or Habit: Represents exemplary characteristic(s) of the species. Some component of tree size, most frequently trunk diameter, may be used to define a special status tree. Most commonly, a given diameter at 4.5 ft above grade (i.e., diameter at breast height or DBH) is used as the size standard. Additional rules are typically needed to handle trees that are multi-trunked or branch below 4.5 ft. Because the relationships between DBH and canopy spread or DBH and tree age vary by species, different tree diameter standards may be applied to different species. Although a tree diameter standard is fairly objective, the threshold diameter is often set more or less arbitrarily. Other components of tree size, such as maximum canopy spread or height, may also be considered independently or in conjunction with tree diameter. The National Register of Big Trees, maintained by American Forests, uses a point system to rate tree size. Points for each tree are calculated by summing trunk circumference (at 4.5 ft) in inches, tree height in feet, and one-quarter of the average crown spread in feet. This system is used to determine “champion” trees for each species. Some ordinances expressly confer special tree status on state or national champion trees. More local “champion” trees could be defined using the same methods. Species: Special status may be conferred only to certain species of trees. Special status trees are often, but not always, important local, native species or trees that are associated with the character of a community. Certain species that are relatively rare or unique in an area, whether native or not, may also be granted special status. In some cases, species is used to specifically exempt certain trees from special status regardless of size. For instance, weedy or invasive species may be excluded from consideration as special status trees.

Figure 4-4. This Sugar Hackberry adjacent to the Roosevelt Deck is the largest of it’s species on campus
Age: Especially old trees are a link to the past, so many definitions of special status trees include age as a criterion. In practice, tree age is fairly difficult to determine in standing trees unless documentation of tree age exists from historical accounts, photographs, or associations with historical structures. Tree age is sometimes inferred from tree size, especially DBH. However, the relationship between age and DBH varies with species, site quality, management history, and other factors, so DBH is usually only a crude estimator of tree age. Historical value: A tree may be associated with a notable local or regional historical event, person, structure, or landscape, or part of a planting group and/or plan with documented historical significance, etc. Almost every large, mature tree has some historical significance, whether it is recognized or not. Determining whether the historical significance of a given tree is sufficiently notable is therefore a subjective matter. Historic tree status is typically granted by a governing (e.g., city council) or advisory body (e.g., tree commission). Some ordinances automatically confer historic status on trees designated as historical landmarks by certain other organizations (e.g., historical societies). For instance, figure 4-5 shows the Founder’s Oak at the Arboretum which was recognized by the Alabama Historical Society in 2003. In addition, ordinances may assign special status to trees dedicated or planted as public memorials.

Ecological Value: All trees serve a variety of ecological functions. Certain trees or groups of trees may have especially high ecological value because of their location, size, species, and/or condition. For example, a given tree may be an important roosting or nesting site, or food source for certain wildlife species; it may be situated in a location where it plays a critical role in stabilizing soil or providing shade needed by other plant or animal species; it may be an important genetic resource for a local tree population or the species as a whole. Input from trained biologists and ecologists may be necessary to document particular ecological values that may not be obvious to the general public. Cultural Value: the significance of an individual to the Auburn University Campus; traditional values and historic events are important in defining the criteria; may be defined by location/setting, such as an irreplaceable contribution to a significant view or spatial structure of a setting. In example, a heritage loblolly pine in front of Swingle Hall; signifigant as a representative of the original trees that made up the landscape where the Auburn campus now resides. Aesthetics: Since beauty is in the eye of the beholder, assigning special status on the basis of aesthetics is always highly subjective. A tree may have special aesthetic value due to its form, whether it is especially perfect and symmetrical or notably craggy and idiosyncratic. Also, the function that a tree serves in a landscape may be sufficient to justify special status; for example, a landmark pair of trees that frame an entrance. In the absence of other noteworthy characteristics, it may be contentious to base special status upon aesthetics alone. Other Unique Characteristics: This term may be added to the list of criteria used to designate special status trees because it is difficult to anticipate all possible situations of significance. This criterion will again be subjective and typically may be invoked through the approval of the governing body. The AU Tree Preservation Committee will govern the process of Heritage Tree Selection. Potential candidates will be subject to evaluation based on the aforementioned criterion. This process should take place on an annual basis.Potential candidates will be subject to evaluation based on the aforementioned criterion. This process should take place on an annual basis.

PLANTING STANDARDS To encourage a balance between campus landscape aesthetics, functionality and ecological contribution, a preferred species list has been developed. Future projects should utilize the list as needed to ensure both site specific and overall campus landscape goals are met. In line with campus goals of returning to a more sustainable campus landscape, a shift towards native plantings should be adopted. Native plantings, when utilized appropriately, are better adapted to various existing site conditions. Thus, they require less maintenance, watering, pesticides and fertilizers. To further guide plant material selection, the campus has been subdivided into four general landscape planting categories. Each of these planting categories has it’s own unique style and should utilize a unified material language. By consistently coupling the proper plant materials with appropriate planting arrangements, the aesthetic and performance of each landscape planting category will be reinforced. The four landscape planting categories are:
The Natural Landscapes
The Formal Landscapes
Much of Auburn University campus’s remaining native landscapes lie within stream corridors, flood plains and steep slopes - environment’s which can inhibit development. Fortunately, these landscape areas make up a substantial portion of todays campus and provide a framework on which to build more preservation lands in the future.
These manicured landscape areas are typically organized to compliment the architectural stylings of adjacent facilities. They typically occur in the denser, more urbanized sectors of campus and provide a structure to the landscape. These spaces can range from simple expanses of lawn - serving as multi-functional play / gathering spaces - to beautiful, colorful accents which highlight important nodes to campus visitors.
Future capital projects should always minimize disturbance to the natural landscapes which remain. Special precaution should be taken to protect native edges. In addition, future projects should include a restorative component - allowing for the reintroduction of natural landscapes which connect to the existing framework. Natural landscapes should attempt to mimic natural patterns with species selection and plant material arrangements. Formal lines, monoculture and other manicured landscape characteristics should never exists within the natural landscape areas. Instead, designers should provide for biodiversity, informal arrangements and micro-climate appropriate species selection.
The Natural Landscapes The Informal Landscapes The Formal Landscapes The Agricultural / Field Lab Landscapes
Parkerson Mill Creek corridor is a prime example of a natural landscape. Projects in and adjacent to this natural corridor should utilize native species to restore performance to this area. The Informal Landscapes Much of the Auburn University Campus is made up of interstitial landscapes which act as a transition between the natural landscapes and the formal landscapes. These spaces should lean heavily towards the style and aesthetic of the natural landscape in order to increase sustainable and performative landscapes in-line with the campus landscape vision. These connective landscapes should utilize informal planting design made up of mostly native plant materials. These landscapes should also arrange plant materials to compliment the multi-modal network it supports. As these landscapes approach the more formalized landscapes of the urban core, they can begin to transition in form and material as needed to support the surrounding environment appropriately. In general; however, manicured landscape treatments should be held to a minimum within this landscape category.
These landscapes will include higher maintenance plant material, however their use should be minimized as is essential. Formal planting arrangements including tree allees, evergreen hedge rows and seasonal color beds should be limited to use within this planting category. Examples of the Formal planting category landscape includes Samford Park and Ross Square. The Agricultural / Field Lab Landscapes This planting category represents the functional landscapes which support the education and research goals of the University. Its importance dates back to the Land Grant Heritage of Auburn University. These landscapes are typically found beyond the campus core as they tend to include large expanses of forest, meadows and / or agricultural plots. Each field lab and / or agricultural landscape is uniquely tied to the purpose it serves for it’s user base. Therefore, planting design within this category shall be chosen first and foremost with utility in mind. However, as with any future development on campus, consideration shall be given towards more sustainable landscape techniques when possible. Water sensitive irrigation, harvested storm water re-use, composting and landscape material recycling should all be considered as potential maintenance and operations practices. Example landscapes representative of this planting category include Old Rotation and Ag Heritage.
campus-wide standard PREFERRED SPECIES LIST The following list of plant materials has been compiled to inform future project planting designs on the Auburn University campus. This list will provide enough diversity to encompass the needs of the wide variety of site conditions across campus. Whether a project is in a more naturalistic setting or a formal one, this list can be utilized to inform planting design across all of the fore-mentioned planting categories.

CANOPY TREES campus-wide standard PROHIBITED SPECIES LIST As opposed to the preferred species list, the prohibited species list is made up of plants which should be excluded from plantings on campus. These species have been determined to be invasive or to have strong potential to become invasive.
Invasive species require special attention around the Auburn campus. Many of the invasive species that have made their way to the Auburn area have done so due to their ability to spread effortlessly. Over time this characteristic; however, has caused these same species to become destructive to the very ecosystems we rely on. Invasive species compete for and often dominate native species for resources necessary for survival including light, soil nutrients and water. This ultimately causes a reduction in the biodiversity of our ecosystems and decreases functionality. Thus, in no case shall any species known to be invasive or approaching invasiveness be utilized on campus. This Prohibited Species List should not be considered exhaustive of all plants recognized for invasive properties in the Auburn area. For a comprehensive list of plants invasive to the area, refer to the Alabama Invasive Plant Council website at http://www.se-eppc. org/alabama List Identifiers (Rankings refer to designations of the Alabama Invasive Plant Council) 1 - extensive and dense infestations in AL 2 - scattered and localized infestations in AL Watch list – recently appearing in AL as free living populations or invasive in adjacent states and cultivated in AL Plant of concern – species being assessed by ALIPC due to reports of escaped populations within the state and species is known to be invasive in other areas of the country

TURFGRASS The Auburn Campus utilizes vast expanses of turfgrass for open space, recreational opportunity and gathering areas. Turfgrass is a great resource to the campus, but requires much higher maintenance than less manicured, natural landscapes. In general, the campus should seek to reduce the amount of highly manicured turfgrass areas - moving toward the use of more-natural meadows when appropriate. All lawn areas within the campus core which receive high user activity and visibility, such as in figure 4-18, shall be sodded with either Tifway 419 Bermuda grass or Emerald Zoysia grass. Species selection shall be based on site specific requirements. Tifway 419 Bermuda Turfgrass is best in full sun and is extremely durable. It grows back quickly when disturbed. Emerald Zoysia turfgrass is best specified on sites where durability is not an issue as it is slow to recover when disturbed. It has a better tolerance for shade than bermuda.
MULCH All Campus landscape planting bed areas shall receive sufficient mulch covering as defined below. Mulch treatment offers many important benefits which assist in the health of the adjacent plant material. These benefits can include pest control, moisture retention, erosion and sediment control, weed control and soil nutrient retention. Still the aesthetic value of a well mulched landscape can not be understated. The various types of mulch materials utilized on campus shall be organized based on their surroundings. If applied properly, they can contribute to defining the character of the spaces they inhabit. Three types of mulch have been defined for consistent use across campus: pine bark mulch (figure 4-20), pine straw mulch (figure 4-21) and recycled or composted mulch (figure 4-22). The other various types of mulch currently found on campus, but not listed here (i.e. - crushed brick) should be phased out moving forward as feasible. Mulch shall be maintained on a seasonal basis as to ensure consistent coverage throughout all beds. Minimum depths shall be installed and maintained as follows:
MEADOWS Areas which do not warrant a highly manicured lawn system should utilize native grasses and wildflowers, see figure 4-19, for a more natural meadow feel. These landscapes offer a more sustainable option as they require little to no regular maintenance, offer increased biodiversity and better manage stormwater runoff. For areas which only receive use during limited seasons of activity, meadows can be mowed to functional heights as needed. For example, AG Heritage Park is used by alumni during football season, but remains underutilized for much of the year. This area should be maintained as a meadow which is then mowed back during the activity season.
Pine Bark Mulch : 3� thickness
Figure 4-20. Primary spaces should receive pine bark mulch as depicted here in the Ginn Engineering Courtyard
Pine Straw Mulch : 3-4� thickness Recycled or Composted Mulch: 3-4� thickness
Type A - Softwood Mulch Installation, maintenance and irrigation standards shall be followed as defined in the Auburn University Facilities Management Design Standards, Section G20 - Site Improvements.
Softwood mulch shall be applied in all primary designated spaces throughout the campus core. Softwood mulch provides a thick, clean coverage and which enhances the edge between planting beds and adjacent turfgrass areas. This sharp look is ideal to achieve a positive campus appearance within heavy traffic areas of the campus core. Type B - Pine straw Mulch Pine straw mulch shall be utilized as the standard mulch application across the campus. Pine straw is appropriate in the Alabama landscape due to its high availability. It is also the least expensive of the mulch standards allowing it to cover large expanses most efficiently.
Figure 4-21. Standard Campus planting bed treatment should include pine straw mulch
Type C - Recycled or Composted Mulch The University should strive to reuse mulching materials on campus. General landscape maintenance in the way of mowing grass, raking/blowing leaves and pruning trees produces incredible amounts of landscape waste. This waste should not be hauled off but, rather stockpiled, properly treated and later reused across campus for mulching needs.

STORMWATER MANAGEMENT STANDARDS
campus-wide standard
In line with the goals of a more sustainable campus environment, Stormwater Management Practices should become one of the University’s most celebrated landscapes. These practices should form the bridge between the “living” and “constructed” landscapes. By constructing stormwater controls which utilize living processes, the campus can improve the quality of water within the surrounding watersheds, reduce the quantities of water discharging, offer educational opportunities to student’s regarding proper stormwater management and even provide aesthetically pleasing landscapes for enjoyment throughout the campus. Stormwater management landscapes can be visible, surface treatments or non-visible, sub-surface treatments. Visible stormwater management landscapes offer the most benefit by allowing interaction with campus users. Thus, when possible they should be utilized with precedent over non-visible alternatives. This design guidelines section offers standard material palettes to inform the design of visible campus stormwater management systems.
Figure 4-23. This bioswale utilizes plant physiology to treat and reduce quantity of stormwater runoff
Figure 4-24. Infiltration ditches should utilize a mixture of grey and brown river stones to mimic natural streams indigenous to the central Alabama region
For more information on stormwater management practices, including insight into their construction and maintenance, see Section 5: Post-Construction Stormwater Control Measures and the Auburn University Stormwater Operations and Maintenance Manual. The following best management practices (BMP), highlighted in these documents, should be utilized on campus: VISIBLE ENHANCEMENTS PERMEABLE PAVING BIO-RETENTION ENHANCED GRASS SWALES INFILTRATION TRENCHES AND DRY WELLS REGIONAL DETENTION (WET) AND DRY DETENTION
NON-VISIBLE ENHANCEMENTS SUB-SURFACE DETENTION

“LIVING” STORMWATER MATERIALS Stormwater Best Management Practices such as bio-swales and rain gardens offer “living” water quantity and quality control. To function at optimal performance, the right vegetation selections must be made. Plant Material selection can become complex as vegetation must be adaptable to periods of drought and inundation. Similarly, inundation levels at various elevations are dependent on many factors including slopes, soil types, percolation rates and the water table. Keep in mind that basic plant material selection factors such as sun exposure and seasonal interest still apply. As each application requires site specific considerations, the following references shall be consulted prior to the design of “living” Stormwater Management Areas: 1. Alabama Handbook for Erosion Control, Sediment Control and Stormwater Management on Construction Sites and Urban Areas 2. Volume 1 - Developing Plans and Designing Best Management Practices. Alabama Soil and Water Conservation Committee. Montgomery, Alabama. 3. Alabama Low Impact Development Handbook, Alabama Cooperative Extension System. www.aces.edu/lid 4.

Auburn University Landscape Master Plan, Comprehensive Campus Master Plan Update 2014
“CONSTRUCTED” STORMWATER MATERIALS Stormwater Best Management Practices can also include constructed landscape materials such as pervious paving, infiltration ditches and underground cisterns. When utilized properly, these techniques can effectively manage stormwater runoff by encouraging infiltration and / or collection. To effectively utilize stormwater BMP’s, the designer must first understand potential stormwater volumes of a given site. This can be based on many factors including average rain amounts, amounts of pervious vs. impervious surfaces, contributing drainage basins, soil types, and more. Proper analysis of a sites hydrology should be performed by a licensed professional civil engineer prior to the design of any Stormwater Management Practices. Once all criteria is known, the designer can decide on the most effective methods to manage stormwater for a given site. Many times it is useful to utilize multiple BMP strategies in an interconnected system. Site program elements should be supplemented by rather than hindered by stormwater BMP’s. For instance, pervious pavements can replace traditional impervious areas, such as shown in figure 4-30, where pedestrian accessibility is required.

SITE WALLS Across campus, standards should enforce the hierarchy of spaces by utilizing distinct material transitions . Four different types of site walls have been defined to complement the various use hierarchies. Through consistency gained by applying these standards, the overall character of the campus is reinforced.
Figure 4-33. Brick wall with a granite cap
Type A - Brick Wall with Granite Cap In line with the iconic materials palette proposed throughout these standards, the Type A walls should include a granite treatment. Type A walls shall be brick faced CMU walls with a granite cap to match the existing seat walls at Toomer’s Corner as shown in figures 4-33 and 4-34. See Figure 4-35 for the granite cap detail.
Figure 4-34. Figure 4-35. Brick Wall with Granite cap detail
Type B - Brick Wall with Precast Cap The University has long utilized the standard wall detail of brick facade with a white cap. There have been many interpretations of this standard and inconsistencies can be seen across campus. In just about every application, a detail variation on the cap has been made including alterations on material, shape and size. After review of the many variations, it is determined that a single standard cap detail should be adopted as pictured in figure 4-36 and detailed in figure 4-37. The cap should be pre-cast concrete with a relatively flat top (sloped to drain) and a beveled edge. This will accommodate use as a seat wall when appropriate. The cap shall be 4” thick x 18” wide x 3’ long.

Auburn University Landscape Master Plan, Comprehensive Campus Master Plan Update 2014
Type C - Brick Wall with Brick Cap Secondary walls should be used in lower-traffic areas within the campus core such as secondary pedestrian corridors. In these applications, a standard running bond brick wall with soldier header brick cap can be used. Weep holes shall be provided by the absence of mortar joints in strategic locations as shown in figure 4-38.

Type D - Concrete Wall Tertiary walls should be used in areas where function is the primary need. This will apply to areas outside of the campus core, maintenance areas, or even areas of low-visibility around buildings. In these applications, a standard concrete wall can be acceptable (see figure 4-40) as it provides an economically feasible alternative to brick. Concrete walls should be poured in place and have a beveled edge top. Height and width will be determined on a structural needs basis.
Landscape Standards

PAVING Pedestrian corridors can better be interpreted when defined by material typologies. From the Iconic spaces of the campus core to the less traveled extended campus locations, paving materials should associate with their environment. Paving details should be more elaborate and colorful in areas of high interest. Similarly, they should blend in when functionality is all that is required. For all paving types, the following paver materials shall be utilized: Standard Style Information: Model: English Edge Color: Full Range Red Alternate / Fill Color: Buff
Pervious Style Information: Model: StormPave Color: Full Range Red Alternate / Fill Color: Buff
Type A - Special Paving
Manufacturer Information: Pine Hall Brick 2701 Shorefair Drive Winston-Salem, NC 27105 800-334-8689 www.pinehallbrick.com
Type B - Decorative Brick Patterns
Type C - Concourses - Concrete with Brick Bands
Primary paving patterns should be used to highlight important junctions along major corridors. The Concourses typically transition to a primary paving pattern in front of important building entrances, at plaza areas where campus users should gather and at the intersections of pedestrian corridors. The materials should shift in these locations to a grid pattern of light brick against the darker campus standard brick mix. The perimeter of these grids should accentuate the form of the area with bands of soldier course brick. Examples of primary paving treatments include the entrance to Haley Center and the plaza outside the coffee shop (see figure 4-44).
The standard paving pattern for pathways over 12 feet should be this ocre colored concrete walk with brick banding (as shown in figure 4-46). The triple row of brick accents help to break up the monotony of large expanses of continuous concrete. In addition, the brick bands help guide the pedestrian down the path. Examples of this paving type occurs throughout the concourse areas. Reinforced mortar should be used to secure the edge brick pavers.
Figure 4-44. Primary corridor areas highlighted with light-colored herringbone brick pavers and darker brick bands
Figure 4-46. Brick bands accentuate the edge of the ocre colored concrete pavement and provide rhythm during a stroll
Areas of special interest should be defined as such. These can be at the location where two primary corridors come together, the grand plaza of an important building, or encompass the area surrounding one of campus’ legendary monumental spaces. In the spaces only, the campus should diverge from it’s standard material palette of brick and concrete to accentuate the location. In line with other specialty treatments around campus, including the Carroll Commons (see figure 4-42) and the curbing at Toomer’s corner, the iconic spaces should offer granite. The granite adds a distinguished look that differentiates one among the standard campus palette.
Figure 4-42. Proposed iconic paving should be similar to granite paving at the grand stair entrance to the Carroll Commons

Auburn University Landscape Master Plan, Comprehensive Campus Master Plan Update 2014
Type D - Concrete with Brick Bands
Type E - Concrete Paving
Type F - Asphalt Paving
Throughout the core campus area, most pedestrian corridors should utilize this secondary paving system. In higher visibility areas, an ocre colored concrete should be used. The ocre colored concrete walk with brick banding (as shown in figure 4-49) combines aesthetics, functionality and feasibility. This paving type should be used for walkways 12 feet or less in width. The single row of brick accents help tie the walkways to the surrounding vertical elements in site walls and buildings. The brick row should be held in place with a perimeter concrete edge to keep the bricks from popping off with use.
For much of the extended areas of campus a tertiary paving treatment should be applied. This paving type should promote functionality and feasibility above all else. A concrete paving treatment with ocre color should be used to run sidewalks to distant perimeters of campus. To add interest to large expanses of concrete, additional scoring can be added which mimics the brick banding utilized for secondary paving (see figure 4-50).
For certain specific areas and applications on campus (such as multiuse trails) an asphalt paving treatment may be employed. This paving type should serve as a practical and affordable alternative paving treatment for non-critical locations on campus. This material may only be used if approved by the University Architect. (see figure 4-53 and 4-54).

STAIRS The use of stair sets should be minimized to maintain accessibility across the Auburn campus. Situations that warrant the use of stairs can include opportunities to provide a shortcut route between two destinations or an opportunity to create a grand entrance. Staircases should generally consist of concrete treads, but can be enhanced in many ways based on function and location. For instance, a staircase leading into an adjacent building should offer detailing compatible with the building’s material language. Similarily a staircase within a plaza space should adopt the language of the plaza’s materiality. Figure 4-53 below shows how brick cheekwalls were used to enhance the surrounding materiality. Material enhancements can come in the form of railings, cheek walls, landing areas and even risers. Designers should work closely with Auburn University Facilities Management to determine proper staircase treatments.
CROSSINGS Type A - Raised Crossing In major pedestrian and vehicular conflict areas, crossings should be geared heavily on the side of the pedestrian. Vehicles should be forced to reduce speed and yield to accommodate pedestrian safety. Primary crossings should accommodate this by utilizing several techniques. First, a raised speed bump. Next, the introduction of a distinct material change signals to the driver that something is ahead and speed should be reduced. Primary crosswalks should consist of brick and concrete. The brick should sit atop the raised crossings and consist of a herringbone pattern with a soldier course around the perimeter. Concrete should fill the slopes of the raised crossing and provide a border for the brick table. See figure 4-55 for a typical raised crossing. Figure 4-57. Raised crosswalks like this one in front of the forestry building should be used for Primary Crossings
To promote additional gathering space adjacent to buildings or plazas, larger stair steps can be introduced as seen in figure 4-54 below.
Type B - Paved Crossing In secondary crossing areas, the pedestrian again takes precedent. In these crossings; however, the amount of vehicular and pedestrian conflict is much less than in your primary crossing areas. Thus, raised crossings are not warranted. The change in material should be enough to signify the importance of the pedestrian right-of-way. Figure 4-56 shows an example of how this might potentially look. Concrete paving with accents of brick banding should run the length of the crossing.
Figure 4-58. Secondary Crossings should contain concrete paving with brick bands as depicted in this proposed rendering Figure 4-55. Concrete steps should be utilized for the majority of campus staircases
Type C - Standard Crossing For crossings outside of the primary pedestrian corridor areas, a standard DOT style crosswalk should be utilized. These crossings should include 12” longitudinal and 24” perpendicular white thermoplastic striping as pictured in figure 4-57.

DETECTABLE WARNING STRIPS There is currently a lack of detectable warning strips on campus. Detectable warning strips are a requirement of the Americans with Disabilities Act (ADA) and should be provided on all ADA ramps on campus. Detectable warning strips must be made of a material that contrasts greatly with the surrounding paving material. As most of the ADA ramps on campus are made of concrete, a brick colored detectable warning strip should be provided (see figure 4-58). This will provide contrast within the surrounding pavement, but also provide unity within the overall Auburn materiality context.
DETECTABLE WARNING PREFABRICATED MAT A prefabricated detectable warning mat may be used in limited, non-critical locations on campus. The Cote-l Industries product, or other approved Alabama Department of Transportation product, as shown below may be used only where, and if, approved by the University Architect.
DECORATIVE TREE GRATES Tree grates should be utilized in the campus core areas when trees are introduced within plaza or concourse areas. For these applications, the University standard tree grate by Barrycraft of Birmingham should be specified. Figure 4-59 shows the standard tree grate treatment amongst a pedestrian concourse.

SITE FURNISHING STANDARDS campus-wide standard LIGHTING In order to support the University’s long term goals, the standard specifications should be updated to include the use of sustainable lighting options. Fixtures should be upgraded to LED on an ongoing basis as old fixtures reach the end of their life cycle. Also, by providing cut-offs, light can be properly directed and unnatural light spillage is minimized. Auburn can increase efficiency while managing environmental stewardship through the use of Dark-Sky compliant fixtures. campus-wide standard

They should utilize proper cut-off design to limit light spillage and contribute to dark sky goals. They should utilize an LED light source for increased energy savings.
RECESSED STAIR LIGHTING When stair cases are necessary in high traffic areas additional safety lighting should be provided with a recessed fixture. Recessed stair fixtures can highlight the treads increasing visibility beyond that provided by overhead lamps. The fixture should be housed with a dark bronze cut-off shield (see figure 4-66).

Standard Bench Benches should be heavily dispersed along streets and pedestrian corridors. In addition, they should be offered at the perimeter of plazas and other open spaces. They can be grouped within larger plazas and building entrances. Benches should typically be accompanied by shade trees or structures that offer relief from the sun. Benches should also be paired with litter receptacles to provide convenient waste disposal for users. Generally benches should be set with the back legs near the edge of the pavement - opened up to the space allowing for comfortable seating and prime “people watching” potential. The campus standard bench should be the Victor Stanley Steelsites Series as pictured in figure 4-69. Benches should always be anchored to a concrete footing or pavement sub-slab. Placement should be at the discretion of the designer. Typically benches should be placed on a solid or gravel type surface; placement on turf or mulch areas is not recommended.

This bench can be utilized in the more serene, natural settings of campus such as the arboretum. This standard is unique in that it combines a garden style feel with a durability consistent with the other campus standard furnishings. To further distinguish it from the other site furnishings, the finish should be a gray powdercoat as opposed to the standard bronze. See figure 4-71 for the campus specialty bench.

campus-wide standard PICNIC TABLE Picnic Tables can meet many different needs across a campus environment. They can be dispersed in campus core plaza settings to provide study/gathering spaces for use between classes. They can also be located at the edge of natural areas where one can retreat for peace and quiet. Plus, buildings might offer a picnic table for users to enjoy a quick lunch break outdoors. Currently picnic tables are under-utilized on campus and do not conform to the campus standard furnishings palette. Non-conforming tables should be replaced at the end of their life-cycle with the University standard depicted in figure 4-72.

campus-wide standard WASTE AND RECYCLING RECEPTACLES In order to maintain a sanitary, attractive campus grounds, the sufficient inclusion of waste receptacles is critical. Recycling receptacles should also be provided at each waste collection location to promote campus sustainability initiatives. Receptacles should be placed strategically within all major corridors, adjacent to seating and gathering areas, and at building entrances. Campus standard waste receptacles are pictured below in figure 4-76 and 4-77. Campus standard recycling stations are shown in figure 4-78.

FENCING / BARRIERS ORNAMENTAL GUARD RAIL / FENCING In areas of higher visibility, decorative railing should be used to line ramps, create barriers and define spaces. Figure 4-84 shows how ornamental fencing is used to define an edge along a concourse. In combination with low growing shrubs these fences can become an attractive site element. Decorative fencing should be constructed with square steel railing. Pickets should be set 4” O.C. to allow for use as a guard rail when required. Minimum guard rail heights will be 42” versus the standard 3’ fencing detail shown in figure 4-85. Railing should be finished with Benjamin Moore Deep Bronze 62’ (Custom color 16362).

Figure 4-92. Staircase with standard railing connects the parking deck to the Forestry Building
STANDARD FENCING To create barriers around sports fields and other large recreational spaces, the University standard chain link fence should be used. Height should be sufficient for adjacent uses to provide separation as required. Finish should be black as shown in figure 4-86. To shield unsightly activity, chain link fence may be accompanied with privacy slats. Chain Link slats provide a clean, durable barrier without the extensive costs upgrades of other screening options. Privacy slats should be black to match the chain link fence. See figure 4-87 for an example.
STANDARD RAIL The University standard railing should be utilized in areas where the ornamental fencing is unnecessary. This would include sites outside of the campus core areas like near the Forestry Building as shown in figure 4-88. For stair railing, no pickets should be provided (see figure 4-89). However, the standard ramp railing should include pickets set at 4” O.C. which will also accommodate use in guardrail settings. In this function, the fence should be a minimum of 42” in height. Standard railing should be finished with Benjamin Moore Deep Bronze 62’ (Custom Color 16362).

DECORATIVE BOLLARDS The University standard bollard should be used to protect buildings from vehicular damage adjacent to loading docks and driveways. Removable bollards should be provided where major pedestrian pathways must allow temporary access for service and emergency vehicles. Removable bollards should provide a locking mechanism to secure them in place when not in use. Both in-ground and removable mount bollards should be of the same decorative style. They should be finished with a bronze powdercoat in-line with the campus standard finishing for site furnishings. Bollard use should be generally limited to restricting vehicles in a pedestrian area and protection of University assets. See figure 4-90 for standard in-ground and removable mount bollard details. Figure 4-93. Decorative In-Ground Mount Bollards should only be used to protect buildings from vehicular damage
campus-wide standard POST AND CHAIN The University standard post and chain should be used along the campus perimeter to direct pedestrian traffic to major access points. Figure 4-91 shows how a properly placed post and chain barrier can deter pedestrians from taking shortcuts through landscape beds. The standard post and chain should include the decorative ball top and have a bronze finish.

EXISTING VEHICULAR BARRIER DIAGRAM CAMPUS BOLLARD / POST AND CHAIN PLACEMENT The campus is currently littered with bollards and post and chain barriers, devices which have been over-utilized to deter tailgating vehicles from destroying the landscape during game day events. However, this approach has instead detracted from the “beautiful, memorable� campus environment that Auburn University seeks to promote. These vehicular barriers not only create physical barriers for pedestrians, often separating walkways from usable gathering spaces, but create an unpleasant image across otherwise aesthetically pleasing campus landscapes. Moving forward, a strategic policy shift shall take place on campus which will lead the landscape towards the vision for the 21st century. The use of vehicular barriers shall be limited to the campus perimeter and strategically placed to create vehicle checkpoints into the central campus core. On game day events, a policing strategy will keep vehicular traffic from entering the heart of campus. This approach will minimize the need for barriers within the campus core returning these areas to landscapes which can again be enjoyed year round. Figure 4-92 shows the current placement of bollards on campus. Figure 4-93 showcases the proposed vision which will create a perimeter around the campus core.

TRANSIT STOPS Alternative transportation means are critical to the ability of a University to effectively move faculty, students, staff and visitors throughout campus. Bus transportation is, and will remain to be, the primary method for movement into and across campus. To encourage greater utilization of this resource, bus service line infrastructure must meet the demands of users. Bus travelers need conveient bus stop locations with safe, comfortable waiting zones. Heavier use transit stops should provide shelter from the elements to encourage use in all seasons and weather events. More remote transit stops should still include ne cessities such as proper signage, comfortable seating and waste receptacles. Across campus, transit stops should respond to their environment in scale, form and materiality.
Type A - Decorative Shelter Primary transit stops are typically located at major pedestrian corridors and gateways into the campus core. These stops should offer an architecturally detailed shelter consistent with its surroundings. Sufficient seating should be provided in the form of benches and / or seatwalls to offer resting places between bus arrivals. Stacking areas should accommodate up to 4 buses at a time. A current example, shown in figure 4-94, is the transit stop at the intersection of Magnolia Avenue and the Ginn Engineering Concourse.
Figure 4-97. Type A transit stop adjacent to a major concourse gateway
Type B - Standard Shelter Secondary transit stops are on the perimeter of the campus core adjacent to heavily used buildings. They too should offer coverage from inclement weather, but lack the capacity needs of the aforementioned transit structures. Also, due to their locations architectural compatibility is less of a concern. A standard bronze finished shelter consistent with other campus furnishings should be provided (see figure 4-95). Due to less frequent trips, bus stacking areas need only accommodate one bus at a time.
Figure 4-98. Type B transit stop with bronze finished pre-fabricated shelter
Type C - Standard Bench Stop At extended areas of campus where trips are less frequent, transit stops should not provide a shelter. The stop should consist of a bench, waste and recycling receptacles and appropriate transit stop signage. Bus stacking is not necessary in these locations. Buses should quickly interrupt travel for the infrequent stops in these locations. Figure 4-96 depicts a typical tertiary transit stop. The bench should match the campus standard. To avoid wear to the turf grass beneath the seating area, a concrete bench pad is recommended. This will also provide a home for the litter receptacles creating a consistent look for stops across campus. Figure 4-99. Type C transit stop should include a concrete pad with bench and receptacles 61
Auburn University Landscape Master Plan, Comprehensive Campus Master Plan Update 2014
UTILITIES The Auburn University campus requires a vast network of utilities to remain operational. A myriad of utility needs including water, power, sewer, telephone and more occur at every corner of the campus. To ensure that the utility network is maximized in relation to the campus landscape in terms of operation, maintenance and aesthetics, a series of guidelines shall be followed when introducing or relocating utility infrastructure on campus. 1. Utilities should not be located in conflict with trees and vise versa. - Trees shall be placed a minimum of 10’ from any existing buried utility. Proposed utilities shall be routed to avoid root zones of existing trees. When both trees and utilities are proposed, utility locations shall be adjusted to maintain proposed tree locations. Maintain a minimum of 10 feet between newly planted trees and proposed above ground utilities. - Proposed canopy trees shall be planted a minimum of 25 feet from aboveground utility lines. Acceptable trees for use under utility lines have been identified in the preferred species list. 2. Utilities should be run in common corridor networks which follow multi-use path corridors to the greatest extent possible. 3. Utilities shall not be placed as to become the focal point of any landscape setting 4. Above-ground utilities including transformers, fire hydrants, cable boxes, utility poles, etc. shall not be placed within a 100’ radius from any buildings primary access points. Figure 4-97 illustrates what should be avoided - utility boxes placed at a main entrance have become the focal point to this residence hall.
Figure 4-100. Above ground utility boxes are now the focal point of this main entrance due to improper placement at the new South Donahue Residence Hall.
5. Above-ground utility boxes, cabinets, transformers, etc., shall be screened from view by use of evergreen hedges or shrub masses where space accommodates,. Where space is restricted, a brick wall screen or privacy fence slats shall be used to screen the larger appurtenances. Plant low shrub masses to screen, to the extent possible, all above-ground utility boxes. Note that these plantings may need to be replaced following utility access or maintenance. Evergreen screening materials acceptable for use around above-ground utilities have been identified in the preferred species list. IRRIGATION As a general rule, the Auburn campus landscape should strive to use less potable water for irrigation purposes and seek every opportunity to capture and reuse water for campus irrigation purposes. The design, management and maintenance of the campus landscape should reflect the landscape water management plan for Auburn University (2007) and the campus sustainability policy.

SURFACE PARKING AND ROADWAY STANDARDS SURFACE PARKING LOTS Surface parking lots are becoming less feasible as spacial concerns continue to grow on campus. In addition to taking up much needed real estate, surface parking lots increase the heat island effect and increase storm-water and erosion problems. Per recommendations in the Comprehensive Campus Master Plan a series of parking decks may be in the near future. Still, surface parking will continue to be a necessary component of a functional campus. In the campus core, surface parking is often required adjacent to buildings to provide ADA access, preferred parking and for other loading needs. On the outskirts of campus, large, efficient expanses of parking are needed to accommodate campus goers in an economical manner. As surface parking areas within the campus core are replaced with regional deck structures, existing lots can be modified to reduce parking spaces. On an ongoing basis, surface parking lots should be evaluated to determine potential for reducing spaces and replacing asphalt with landscape area. Existing surface lots should also be analyzed and renovated as feasible to minimize heat island and stormwater runoff issues. The following standards should apply to all surface parking lots across the Auburn University campus: General Standards The following standards apply to the construction and/or renovation of all surface parking lots (see Figure 4-98): Surface parking lots shall be screened from adjacent streets and gathering spaces by a continuous evergreen hedge at 30” minimum height. Sight triangles per Alabama DOT requirements shall take precedent over screening requirements - the screening treatment may be modified to accommodate sight lines. Parking lot islands must be a minimum of 8’ in width as measured from the back of curb Trees planted to meet surface parking lot standards shall be a minimum of 3” caliper and shall be planted in appropriate tree planting soil mix which contains no more than 50% native soil Fastigiate tree varieties are not permissible as parking lot trees Position parking lot trees approximately 4’ from all adjacent back of curb lines to achieve maximize shading potential Provide 15’ minimum clearance between parking lot trees and dumpster enclosures so as to prevent conflicts No signs or utilities - i.e. transformers, fire hydrants, etc. - shall be placed in conflict with a parking lot tree Light poles shall be located a minimum of 20’ from a parking lot tree Light poles are prohibited in parking lot islands unless authorized by the Office of the University Architect. The site lighting plan must be submitted with the parking lot landscape plan and approval of both plans shall occur simultaneously. Tree planting shall be coordinated with existing and proposed security camera locations
63
Type A - Campus Core Parking Lots Type A standards should be utilized for the smaller, more formal surface lots within the urban core areas of campus. These lots are generally located adjacent to buildings in order to accommodate building users in need of close proximity access. The following standards shall apply: All parking stalls shall be within a 50’ radius minimum from a parking lot tree Design teams should analyze the potential to provide pervious surfaces as an alternative to asphalt Curb cuts should be provided to allow storm-water drainage to reach bio-retention collection areas adjacent to parking surfaces Type B - Efficiency Parking Lots Type B standards should be utilized for the large, expansive surface lots located outside of the campus core. These lots are generally located on the outskirts of campus and accommodate large numbers of cars. Users of these lots must be transported into the campus core via mass transit. Important aspects of Type B parking lot design include the efficient use of space to accommodate a maximum allowance of vehicle spaces, a need to minimize the heat island effect created by large expanses of asphalt and a need to mitigate storm-water runoff caused by massive amounts of impervious surface. The following standards shall apply: All parking stalls shall be within a 60’ radius minimum from a parking lot tree Drive-aisles shall be a maximum of 22’ width for 90 degree parking to reduce asphalt surface Design teams should analyze the potential to utilize pervious alternatives to asphalt Parking lots should drain to adjacent storm-water collection gardens where possible Type C - Gravel Parking Lots Type C standards should be utilized for gravel parking lots which are often used for remote locations of campus. These lots are generally located on the outskirts of campus and allow for parking accommodations without the permanency of impervious asphalt. These lots can be designed to accommodate game-day traffic as well. Without the structure provided by typical curb and gutter and striping, type C parking lot design must communicate parking spaces in creative ways to ensure that maximum accommodations are not jeopardized by poorly parked vehicles. The following standards shall apply: All parking stalls shall be within a 70’ radius minimum from a parking lot tree Railroad ties and / or wheel stops should be utilized to delineate spaces and protect parking lot trees. Placement around trees should minimize parking over a tree’s critical root zone.

ROADWAY DESIGN GUIDELINES MATRIX ROADWAYS The roadway network across Auburn University consists of a series of important arteries which define the campus “grid”. It is a hierarchical system of corridors which generally run both north-south and east-west. Seven corridors have been identified as being primary; these are the most important in defining and maintaining the campus landscape given the importance of their function and role. Together, these primary corridors unite the campus while being expressive of the distinctive characteristics and values of Auburn University. In addition, a series of supporting, secondary and tertiary corridors have been defined which help complete the essential corridor network which connects the Auburn campus. The Primary Landscape Corridors include: 1. College Street 2. Mell Street 3. Concourses (Tiger, Haley, Duggar, Roosevelt) 4. Donahue Drive 5. Magnolia Avenue 6. Thach Avenue Secondary Corridors: 7. Duncan & P.O. Davis Drive 8. Wire Road 9. Samford Avenue 10. Lem Morrison Drive Tertiary Corridors: 11. Biggio Drive 12. Hemlock Drive 13. War Eagle Way 14. Heisman Drive *Note: College Street and Magnolia Avenue are not property of Auburn University; however, these corridors are of great significance to the function and aesthetic of the campus landscape. As many of these corridors extend across multiple campus environments, a “one-size fits all” standards approach to each corridor is not appropriate. Therefore, corridors have been further sub-divided into segments which exhibit common urban design characteristics. To restore consistency and contribute to the overall effectiveness of each corridor segment, future projects should adhere to the roadway design guidelines matrix in Table 4-6. Further explanation of the bicycle facilities types and street tree group types continues on the next page.

PRELIMINARY BICYCLE ROUTES AND PARKING RECOMMENDATIONS
W Magnolia Ave
N College St
The roadway design guidelines matrix in Table 4-6 proposes the use of multiple types of dedicated bicycle facilities. As a starting point, the preliminary bicycle routes and parking recommendations as seen in the Campus Master Plan Update 2013 was consulted (see Figure 4-99). This preliminary plan deliniates bicycle routes and differintiates them as occuring on-street and / or off-street. To further expand on this approach, multiple types of facilties have been identified and applied as appropriate to the corridor segments in the roadway design guidelines matrix. Table 4-7 shows a list of the various types of bicycle facilties. Proposed on-street route options include dedicated bicycle lanes and cycle tracks. Proposed off-street bicycle facilities include multi-use trails, dedicated bicycle paths and shared pedestrian and bicycle routes. Future design teams should incorporate the proper bicycle facilities for the corridor segment associated with their project area.
N Donahue Dr
Bicycle Facilities Types
Street Tree Group Types Each corridor segment should seek to achieve a consistent look. However, an evenly spaced, single-species tree allee’ should be avoided. Consistent with the landscape vision for a sustainable campus landscape, reforestation practices should be applied throughout the campus core. Street corridor landscapes are not an exception. Instead they offer a great opportunity to reconnect forest fragments.
W Thach Ave
Tree arrangement along the corridors should consist of informally spaced tree groupings made up of compatible street tree species as determined by the street tree group types (see Table 4-8). Tree placement shall aim to highlight interesting view corridors while screening less desirable ones. Trees should also be placed to maximize shade potential on adjacent pathways. However, tree plantings should also follow the setback guidance as listed in the roadway design guidelines matrix. Finally, tree placement should remain functional - adequate sightlines shall be maintained at all times.

GATEWAY STANDARDS
Perimeter Gateways
Gateway elements serve as the front doors of campus. By directing traffic to these strategic locations, one can better guide visitors through predetermined experiential routes to key destination points. Gateways range in importance from iconic to secondary based on their location, traffic volume expectancy and even cultural importance.
Perimeter gateways should be strategically located along the major vehicular travel routes into and out of the Auburn area to signify the outer campus boundaries. In Figure 4-102, proposed locations for the perimeter gateways are shown. Due to their location at the outermost reaches of the campus, these gateways should perform effectively, in scale and placement, with vehicular use in mind. The scale shall be such that these gateways can make a visual impact on a vehicle traveling at speeds close to 45 miles per hour. Also, they should be located as to acheive optimal visibility from adjacent travel lanes. To best achieve this effect, perimater gateways should be placed at key intersections approaching campus. They will be designed to read across both sides of the intersection in order to grab attention from all directions of travel.
Often times these thresholds can offer opportunity for increased aesthetics to help generate a great first impression to University visitors. They can be parklike and offer gathering opportunities as well. The University should adopt a consistent gateway language that exudes the Auburn character and defines ones arrival. All gateway design shall conform to the Auburn University Sign and Wayfinding Manual, 2009. The Iconic Gateway Toomer’s Corner is the iconic gateway with it’s combination of cultural significance and strategic location adjacent to downtown Auburn (See figure 4-102). This gateway serves as the front door to campus. Campus visitors often traverse the historic 1917 gates at the corner as they enter campus through Samford Park towards Thach Concourse. The backdrop of this iconic gateway includes Samford Tower and Hargis Hall which are two of the more identifiable buildings on campus. Added cultural significance for this gateway has built over the years through the tradition of “rolling the Auburn Oaks”. The importance of this gateway to the campus community can not be understated and thus, iconic treatments should be given when design or modifications are needed. This gateway should utilize special/iconic paving, walls, furnishings, etc. as detailed throughout this Landscape Standards document. Core Campus Gateways
Internal Campus Thresholds Internal Campus thresholds as indicated on Figure 4-102 should delineate the entrance to various campus regions. Although these wayfinding accents should read consistent across campus in terms of materiality, they can vary somewhat in scale and form based on their environment. At it’s outermost locations, such as the intersection of Lem Morrison and Wire Road, these thresholds can be of a vehicular scale and span whole intersections. In the urban core, the standard column structures currently utilized are appropriately in-line with a pedestrian scale. See figure 4-100 for an existing column structure on Mell Street.

The Core Campus Gateways occur along Magnolia Avenue and South College Street as shown in figure 4-102. These gateways are multi-functional entrances to the urban campus core which must signify the campus edge while handling wayfinding needs and bus transportation loading zones. See figure 4-101 for a typical treatment of a core campus gateway as shown at the Ginn Engineering Concourse gateway along Magnolia Avenue. Each of these gateways is connected to a major pedestrian concourse and should signify this importance in scale and materiality treatments. Landscape Standards defined as primary importance treatments should be applied in the way of paving, walls, furnishings and transit structures. To best connect the core campus gateways to adjacent uses off campus, clearly delineated pedestrian crossings should be applied. These crossings should give precedent to the pedestrian over vehicular uses with Type A - raised crossings as shown previously in this section. Crossings should be perpendicular to the travel way and provide direct alignment to the gateway and it’s destination concourse.
