INTRODUCTION The Landscape Master Plan envisions restoring the landscape as the defining character of Auburn University. This Design Recommendations section offers a closer look at how this vision can be realized through the application of the landscape standards. This section provides both a general assessment of the existing landscape and suggests recommendations for potential improvements. These existing conditions and recommended improvements are typically illustrated in plan diagram and section form and accompanied by a series of illustrative photographs.

For this exercise, the campus corridor network and four prioritized focus areas were chosen for analysis. Together these spaces illustrate a representative sample of the various landscapes across campus.

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 (Ginn, Haley, Duggar and Roosevelt) 4. Donahue Drive 5. Magnolia Avenue* 6. Thach Avenue and Concourse

The symbology shown in Figure 6-7 is utilized throughout the design recommendations section to diagramatically showcase the existing assessments and proposed improvements.

Overall Corridor Diagrams At the beginning of each corridor segment, the general makeup of each corridor is highlighted on an overall map diagram. The diagrams all utilize the same legend. A solid blue circle indicates an important intersection along the corridor and a dashed blue circle indicates that intersection will be addressed in another corridor section. The red cut/ section lines indicate the locations of illustrative sections and their orientation. The orange line and tone indicate important, sometimes iconic, landscape areas within the corridor.

Performance Metrics Each of the Primary Corridors identifies an existing and proposed set of landscape performance metrics. These metrics are: landscape maintenance, pavement permeability, trees/shade, and intensity of use. Below is a description of each with an explanation of the diagramatic language utilized.

LANDSCAPE MAINTENANCE:

PAVEMENT PERMEABILITY:

TREE / SHADE:

INTENSITY OF USE:

Figure 6-8. Typical existing and proposed maintenance metric diagrams.

Figure 6-9. Typical existing and proposed pavement permeability metric diagrams.

Figure 6-10. Typical existing and proposed tree / shade metric diagrams.

Figure 6-11. Typical existing and proposed intensity of use metric diagrams.

Existing conditions maintenance metrics are based on observations of current maintenance regimes. The highest maintenance areas, represented by indicate areas that are highly planted, paving is well cared for and in most cases are iconic spaces for the university.

Medium maintenance are typically areas adjacent to the high maintenance areas. Low maintenance areas are often ancillary in nature and may be nothing more than grass or asphalt.

Existing conditions pavement permeability metrics note locations of existing impervious pavement on campus. With the exception of some plaza areas and paths in the arboretum campus paving is for the most part impervious. Impervious surfaces are noted as .

Existing conditions tree / shade metrics note existing amount of tree canopy and approximate size. This figure ground study of available shade indicates areas where little or no shade is available.

Given Auburn University’s warm climate having accessible shade is necessary for the comfort of faculty, students and staff.

Intensity of use refers to the amount of faculty, students, staff and alumni that use a space and with what frequency. Areas around major classroom facilities with high rates of traffic by students are often the most intensly used spaces on campus and as such care should be given to their finish. Considerations such as durability, scale, and quality of materials will affect these locations and their ability to accommodate amounts of traffic adequately.

Often the maintenance metrics and ‘use’ metrics are similar because areas that people use the most are often maintained to a higher standard or require more maintenance because of the use of the space.

The proposed metrics shown, when coupled with the design suggestions in the landscape corridors section, suggest where areas may change in maintenance type based on use and finish.

These estimates are based on square foot areas taken from the campus cad plan per landscape corridor and while they convey the intention, should be considered ‘rough numbers’.

There are some areas where no physical change is proposed but because of an improvement in an adjacent landscape that will draw more use, may be suggested to increase in maintenance level.

Iconic landscapes such as gateways, parks, heritage sites, etc should always receive the highest landscape level to ensure their longevity.

Design Recommendations - Corridors

The proposed permeability diagrams represents areas of potential permeable paving as . The following are areas that may lend themselves well to using pervious paving: Sidewalks Parking lots Plazas Areas where heavy trucks do not access Parks

Proposed diagrams show existing canopies being allowed to reach maturity as well as infill planting of additional trees where major gaps in the shade cover exist. Care should be given to maintain existing tree canopies. When new trees are planted they should be located close enough to pedestrian circulation to provide shade as soon as possible. Trees should also be planted at a large enough caliper (3” or more depending on species) so that canopies can mature earlier. Once trees are planted they should be protected from further disruption and allowed to fill out.

There are three levels of use; low , medium , and high . Low use areas are typically ancillary while medium and high use areas are often central to circulation or gathering spaces.

Proposed architectural program such as the Central Classroom facility, Academic Success center and others will increase the adjacent intensity of use.

Greenways Permeable paving reduces the amount of surface runoff during storm events. Storm water is allowed to permeate paving and penetrate back into the ground water table ultimately reducing the amount of water discharged into adjacent creeks and drainageways.

Since this water is filtered through the groundwater table it’s quality is improved.

Percentages of existing and proposed are based on square foot calculations. In most cases a 50 / 50 ratio of is desirable as it is understood that not all paved surfaces can be pervious as some require higher load ratings.

Major pedestrian / vehicular conflicts existed around the previous oaks at the corner of the park. The oaks were too close to the adjacent streets which created blind spots for both pedestrians and vehicles.

6

9

There is no accessible route at the mid-block crossing and crosswalk. Though lights have been installed, it is still difficult for fast moving vehicles to notice pedestrians in this crossing.

The majority of existing trees are located in areas that have been mulched and often have groundcover and shrubs that prevent pedestrians from accessing available shade.

9

The main pathway from the corner aligns with Hargis Hall.

Samford Hall is only visible obliquely.

The existing paths in Samford Park are often cut off from areas of open lawn by adjacent planting making access to the lawn circuitous. There are multiple paths leading to similar destinations with no real hierarchy between the paths, their widths or paving materials.

8

The existing shrub and groundcover beds employ a variety of mulch types that provide no consistency between planting areas.

9

Adjacent ancillary spaces are thick with shrubs and groundcover which makes them feel separated and inaccessible to the rest of the park.

Samford Park is the setting for Auburn’s most iconic building and a place where many visitors to Auburn first arrive on campus. It is currently characterized by obstructed viewsheds, a lack of pedestrian connectivity and a landscape fragmented by a redundant path network (see Figure 6-13). Usable lawn spaces are largely inaccessible due to dense shrub planting along path edges (see Figure 6-16).

As the setting for an Auburn icon and a main entrance to campus, Samford Park should be a place where visitors, students and faculty orient themselves to campus. Starting here, one should be able to easily navigate to further destinations.

Primary view of Samford Hall Tower is obscured by large evergreen shrubs and trees.

Proposed improvements (see Figure 6-18) include combining paths and opening viewsheds to assist with wayfinding. Also, consolidating landscape spaces to provide continuous areas of occupiable shade. Finally, provide clearings that further emphasize views to iconic spaces and destinations.

1

Remove dense evergreen shrub and tree masses to allow views from the corner to the clock tower at Samford Hall.

2

Move the replacement oaks back from the street and open up the corner to reduce pedestrian and vehicular conflicts caused by blind spots.

3

Provide graded transition to the crosswalk accompanied by pedestrian scale lighting and signage. Make the existing painted crosswalk into a traffic table with iconic paving to slow vehicles.

Use consistent street tree planting to provide shaded walks along the perimeter of the park (reference matrix for suggestions).

4

Open up accessible shaded areas by reducing the amount of shrubs and groundcover. Allow pedestrian access to shaded lawns and views to iconic buildings.

5

Replace the existing oaks with large replacement trees. Open up the existing plaza by removing adjacent evergreen trees and shrubs. Expand the boundary of the plaza for more gathering space.

6

Align the new path with the Samford Hall clock tower and widen it so that it is the predominant path through the park.

7

Reduce the amount of paths through the park by combining them into a few key paths that focus on iconic views and existing forecourts. Vary the paving material so there are primary, secondary and tertiary material expressions of paths.

8

Make landscape treatment and maintenance consistent across the park. Use one type of mulch consistently.

9

Open up secondary spaces for use by relocating dense gardens to areas that relate directly to Samford Hall. Use secondary spaces for smaller, more intimate gatherings.

2

Remove stone mulch and plant native, low maintenance groundcover to define edge of path. Replace missing street trees with trees of equal or greater size than the adjacent street trees to provide shaded walk for pedestrians.

3

Replace current crosswalk with traffic table to slow vehicles and allow pedestrians to cross more safely.

1. 2 COLLEGE STREET: LIBRARY LAWN Existing Conditions Plan Diagram

1

Sidewalk along College Street is contained by a bollard and chain that prohibits pedestrians from accessing the lawn adjacent to the parking garage. This section of sidewalk is also largely unshaded and exposed to heavy, fast moving traffic along College Street.

2

The most shaded pedestrian gathering areas are taken up by large masses of shrubs resulting in minimal occupiable shade.

3

There is only one break in the surrounding bollard and chain that allows pedestrians into the lawn area. This has created a dirt trail that is muddy and inaccessible when the weather is inclement.

4

Minimal screen planting allows views to the side of the parking garage from College Street.

5

Existing Roosevelt Street alignment breaks from the orthogonality of the block. Eastern end aligns with a much smaller, residential scale section on the East side of College Street.

6

Steep slopes around the library prevent pedestrian access to lawn areas.

7

Existing branch of Parkerson Mill Creek is underground in a culvert.

Typical of many spaces in the academic core, shaded areas are unoccupiable due to an under planting of dense shrubs. Access to usable space is further impeded by steep slopes and a continuous line of bollards at the perimeter.

This space represents the headwaters of the Parkerson Mill Creek watershed, the main natural hydrologic resource of Auburn’s core campus. It is currently piped in this location, suppressing its potential ecological value. There is a tremendous opportunity to improve the health of the waterway and the quality and utility of the landscape by daylighting and restoring Parkerson Mill Creek in this location. As part of the campus front yard on College Street, this project could become a usable, beautiful and memorable campus space, as well as emblematic of Auburn’s commitment to ecological restoration and sustainable landscape practices. The restoration of the creek would be integrated with usable lawn spaces, as well as a lower-maintenance landscape of native grasses and shrubs.

1. 2 COLLEGE STREET: LIBRARY LAWN Potential Improvements Plan Diagram

2

1

Create a planting strip between the sidewalk and back of curb to contain a low maintenance native grass buffer. The bollard and chain system should be located within this planting strip. Plant a row of street trees on either side of the sidewalk to create a shaded walk along College Street between Thach and Samford Ave.

2

Formalize occupiable lawn for pedestrian gathering while keeping shade trees.

3

By moving the sidewalk to the park side of the bollards, pedestrians are able to access the open space.

4

Plant large shade trees, understory trees and shrubs along the eastern face of the parking garage to screen views from College Street.

5

Realign Roosevelt Drive to align with Roosevelt Concourse and the pedestrian gateway. Plant street trees along Roosevelt Drive to provide a shaded pedestrian route.

6

Provide access from the upper levels of the park (around the library) via stairs to accessible lawn areas. Other steep slopes should be planted with native, low maintenance shrubs and groundcovers.

7

Daylight Parkerson Mill Creek to re-create ‘Tiger Pond’. This impounded section of Parkerson Mill Creek would have braided wetland edges to increase bank stabilization and would flow over a series of weir walls as it drops in elevation. A meandering path would connect the sidewalk along College Street, past and through the braided wetland benches, to the pedestrian gateway at the Roosevelt Concourse.

2 1 Figure 6-42. Library Lawn Existing Conditions Section

1

When excavation was performed for the construction of the Library, there were small walls built around the existing trees and the critical root zone of those trees has been compromised with additional fill material. This is unsustainable for the trees.

2

Large, loose shrubs under the trees prevent pedestrians from taking advantage of the shade.

3

A narrow sidewalk with adjacent bollard and chain system forces pedestrians along College Street to walk directly adjacent to five lanes of moving traffic. It also prevents them from accessing the lawn and shade between the parking garage and the library. This section of sidewalk along College Street is unshaded and very unwelcoming for pedestrians.

4

The sidewalk on the eastern side of College Street is confined between a small, steep grass planting strip and a bollard and chain system leaving pedestrians feeling exposed to traffic.

Remove the walls around the trees and slope grade. Provide proper drainage so water is not collected.

2

Remove and thin the existing shrub mass to create more occupiable space for people to gather. Add internal pathways for pedestrian circulation. Provide seating areas for people to stop, study or gather.

3

Create a 10’ wide multiuse sidewalk that is inward from the edge of College Street and provide a planting strip between the sidewalk and curb.

Move the bollards and chain to the back of curb and plant planting strip with native, low maintenance shrubs and groundcovers. Plant large shade trees on either side of the relocated sidewalk to improve the pedestrian experience along College Street.

4

Plant a continuous hedge in the planting strip on the eastern side of College Street to give pedestrians a sense of protection from adjacent traffic. Move the bollard and chain system to the back of curb.

Ross Square is a key intersection of main pedestrian routes connecting the core campus to Toomer’s Corner. Major foot traffic moves diagonally between the southwest and northeast corners, yet the direct route is obstructed by trees and shrubs that restrict views from adjacent pedestrian approaches. In addition, the loop road around the square creates dangerous conflicts between vehicular and pedestrian traffic.

Proposed improvements to the square include removing the formal loop road to limit vehicular traffic to ADA and emergency vehicle access. Also, propose a clear the path for the major diagonal desire line by shifting the planting.

This will improve the wayfinding experience and open views from the pedestrian approaches. Figures 6-57 and 6-58 show existing conditions and potential improvements for Ross Square.

2. 2 MELL STREET: NORTH MELL STREET Mostly open lawn in full sun, North Mell Street lacks shaded walks and well defined, comfortable areas for gathering (see Figure 6-66).

Potential improvements include adding trees and shrubs to help distinguish gathering spaces from the spaces of vehicular and pedestrian transit. Also, take advantage of the slopes as usable space by adding seat walls. Finally, increase ecological performance by utilizing rain gardens to filter runoff from the street and slopes (see Figure 6-69).

2. 3 MELL STREET: ROOSEVELT CONCOURSE GATEWAY The vehicular travel lanes, pedestrian paths, and the entrance to the Roosevelt Concourse cannot be easily distinguished from one another (see Figure 6-70).

Adding a distinctive material to differentiate the pedestrian walk will help provide visibility to the crossing (see Figure6-73). This will aid both the pedestrians in finding their way, as well as the people in vehicles watching for pedestrians. The addition of canopy trees will help clarify the gateway as a threshold into the campus core and improve the comfort of usable space.

Figure 6-70. Existing Roosevelt Concourse gateway is currently unshaded and open to Tiger Transit and typical vehicular circulation. Roosevelt Drive does not align with Roosevelt Concourse.

Figure 6-72. View down Mell Street with typical sidewalk adjacent roadway

Figure 6-71. The proposed Roosevelt Concourse gateway should define the pedestrian hierarchy by using a standardized brick traffic table in place of typical painted crosswalks. This will help minimize the pedestrian / vehicular conflicts. Adding shade trees to pedestrian gathering areas will encourage additional use and help frame the gateway to the concourse.

1

Remove the bollard and chain system on both sides of Mell Street (see Campus Bollard Plan figure X.XX). If bollards must remain then they should bee relocated to the back of curb. Move the path away from the back of curb on the western side of the street to allow space to plant an allee of street trees on either side of Mell Street linking Ross Square to the Arboretum with a shaded pedestrian walk on either side of the street.

Replace impervious concrete with porous paving on all pedestrian walks. Any path that connects the main sidewalk along the street to a building entrance should be lined with shade trees. Connect the front yards of the buildings along Mell Street with a series of shaded, occupiable gardens that connect back to the Roosevelt Gateway.

Where possible, replace impervious parking spaces with porous paving to encourage groundwater infiltration. Use native, low maintenance shrubs to screen views of parking from the street.

The existing pond is shallow, appears stagnant, has minimal planted buffer around its banks and could be better located.

5

Site circulation between adjacent elements, like the ‘Hill Dorms’, is not clear.

Existing stream bank lacks diversity and is incised.

The Garden of Memory is intended as a contemplative and relaxing space for students though that potential is undermined by its current condition (see Figure 6-78). Although adjacent to the Hill dorms and the Arboretum, the entrances to the Garden are poorly defined or nonexistent, as is the path network. This ultimately has negative impact on its use and utility.

The many landscape types within the garden lack definition and clear boundaries.

The stream and pond are degraded, the ornamental gardens loosely planted, the lawn edges undefined and the forest under run with invasive species.

The garden has potential to become one of the great campus landscape spaces. See Figure 6-82 for a series of proposed improvements. For instance, if linked more strongly to the Arboretum, the Garden of Memory could be appreciated in the series of campus landscapes that display Auburn’s plant collections. If better linked to the Hill dorms, the garden can become a highly desired natural escape. The path network should be formalized to make these connections. In addition, the path network should be used to reshape, reinforce and distinguish different landscape spaces – ornamental gardens, forest, occupiable lawn and restored stream corridor.

Water can be better integrated and improved as part of the contemplative experience. Through the restoration of the stream corridor and redesign of the pond, the ecological function and appearance within the gardens will be greatly improved.

Another key improvement would address the ornamental collections along the eastern edge. This area has much potential to be further developed and diversified.

As an educational collection, the Davis Arboretum has potential to represent diverse plant communities of the eco-region with an emphasis on forest ecologies. However, the current collection lacks diversity and is dispersed without regard to native hydrologic and topographic contexts of the plants. Over time, the collection should be carefully curated to diversify the species and forest structure. See Figures 6-91 and 6-92 for existing conditions and proposed improvements for the Davis Arboretum.

To increase the educational value and health of the collection, the plants should be located with respect to their native environment. This in turn would require articulating a range of solar conditions and hydrologic contexts.

Since the arboretum is also a space designed to be occupied, the usable lawn space, forest, perennial and shrub collections should be more clearly defined and delineated. Providing distinct areas will assist in creating a more inviting and relaxing environment.

The arboretum is one in a series of landscapes, including the adjacent Garden of Memory and the nearby Agricultural Heritage Park, that demonstrate the ecological types and landscape strategies used throughout the wider campus. This list includes restored natural systems, emphasis on native plants, sustainable agricultural practices and integration of urban ecology. An expanded interpretive center at the arboretum could provide an opportunity for studying and developing these interconnected landscape systems.

The multiple crossings should be concentrated into a single alignment. This new path should be more visible through the use of special paving. Additional shade trees will further improve the visibility of the pedestrian gateway and wayfinding function. These improvements (as shown in Figure 6-104) can help increase the safety of the crossing at this crucial campus entrance.

This intersection of two main pedestrian corridors could be an iconic campus place to meet up and gather. Currently, many of these spaces are poorly defined by irregular boundaries, contain a scattering of unsightly utilities and transformers, and offer a complete lack of occupiable shade. Figure 6-112 shows a typical example at the intersection of Ginn Concourse and Thach Concourse.

The Haley Concourse is one of the most important pedestrian thoroughfares on campus. Current conditions include a lack of shade, vast expanses of pavement, and few pedestrian scaled spaces (see Figure 6-115). The large expanses of impervious paving also contribute to the heat island effect and campus stormwater issues. Opportunities exists to utilize this major pedestrian corridor as a comfortable and functional space. Figure 6-113 shows existing conditions across a section of the concourse.

3.4 CONCOURSES: CAMPUS GREEN Generally well defined and well used, this space could be improved through the addition of shade and some hierarchy of navigation to the path network. See Figures 6-117 and 6-118 for existing conditions and potential improvements to the campus green area.

Existing trees should be given extra care to ensure their health. They should be allowed to mature and eventually grow into a closed canopy grove.

Navigation would be improved through the addition of special paving. This paving can be used to clearly define major paths. New tree planting can also assist navigation by screening the parking garage and directing views inward towards the campus buildings and landscape spaces.

3.5 CONCOURSES: DUGGAR CONCOURSE AND SAMFORD AVENUE INTERSECTION

2

As evidenced at Dugger Concourse and Samford Avenue, existing pedestrian crossings on campus are typically understated (Figure 6-125) and create uncomfortable, unsafe passages. To avoid conflict with vehicular travel, these pathways need to be more clearly defined. The majority of campus crosswalks are standard white traffic stripe on grade. Although this standard is sufficient in most transportation scenarios, it is less than ample in a campus environment where pedestrian traffic is dominant.

2

Small planting stock with too much space between planting and massive expanses of mulch. No shade on pedestrian concourse.

3

Skewed crosswalk confuses pedestrian flow.

To create safe, comfortable crossings in the campus environment, high contrast between the roadway and the crossing is critical. Visual boundaries can be created through the use of paving material contrasts. In many cases, the contrast of a brick and concrete crossing can be sufficient.

For areas with heavy vehicular conflicts, a raised table crossing (see Figure 6-126)can help better identify pedestrian zones.

3

Figure 6-124. Dugger and Samford Intersection Potential Improvements Plan Diagram

1

Increase the size of the existing traffic table where concourse crosses Samford Ave. Carry its length through the median and adjacent parking lot to establish a clear connection between the concourses.

2

Increase size of trees at installation and decrease spacing on shrubs and groundcovers to minimize expanses of mulch areas. Provide more shade along pedestrian concourse and street trees to shade parked cars and walkways.

3

Relocate existing, misplaced utilities and vendors to more appropriate areas.

This major pedestrian and vehicular intersection presents a number of safety conflicts between pedestrians and vehicles. The crossing is a long one. Pedestrians must cross two street corners, a median and a parking lot entrance before reaching the other side of the path (see Figure 6-123). Figure 6-124 shows suggested improvements. This should include making the crossing more visible and substantial by unifying it into a single alignment and applying special paving and increasing the size of the raised traffic table.

3.6 CONCOURSES: DUGGAR CONCOURSE TO SOUTH QUAD In between the dormitories and the Terrell Dining Hall (see Figure 6-129), the Duggar Concourse is a linear walk with numerous adjacent interstitial spaces that can be taken advantage of as informal areas for student gathering (see Figure 6-130). Recommended improvements include allees of canopy trees to bring shade and comfort to the concourse. Also suggested is the addition of parallel raingardens to improve the ecological function and appearance of the space. Where possible, small garden spaces for student gathering and study can be added. Figures 6-127 and 6-128 show existing and proposed cross sections of the Dugger Concourse.

3.7 CONCOURSES: SOUTH QUAD AND OLD ROTATION

BOYD HALL

Divided by a parking garage, parking lots and associated vehicular access, the existing South Quad landscapes are fragments rather than designed spaces serving to emphasize and integrate the academic buildings. The pedestrian experience is designed around vehicular parking and access, rather than intentional safe and direct pathways to campus destinations. As a result, the prominent views are of parking spaces with no relationship to overall campus navigation.

The large scale of the fields plus an existing forest fragment provides an opportunity for restoration of the forest ecosystem. This restoration would also serve to screen views of the garage. While the current path network terminates on the north side of Lem Morrison Drive, the network could extend to include the Old Rotation through trail access and open views from the north. This would highlight and provide interpretation of this ongoing experiment emblematic of the university’s agricultural heritage. Figure 6-133 shows potential improvements for the area.

See Figure 6-148 for an existing aerial view of the corridor. The main entrance to this ceremonial street currently lacks clarity and distinction as shown in Figure 6-145. Also, the gateway feature is currently on the western side of the road only as seen in Figures 6-147 and 6-148. This could be improved by formalizing the street with allees of large canopy trees on the sides and central median, and adding symmetry to the entrance with an additional pedestrian gate on the eastern corner. See Figure 6-146 for a view of the gateway if these proposed improvements were applied.

4. 2 SOUTH DONAHUE DRIVE: SOUTH DONAHUE DRIVE The layout of North Donahue Drive prioritizes vehicular traffic. The pedestrian experience is defined by adjacent parking and traffic with no buffer in between (see Figure 6-155). By shifting the paths away from the street and parking edges, North Donahue could accommodate both vehicular and comfortable, shaded pedestrian walks that integrate raingardens to capture stormwater runoff from the parking to the west. See Figure 6-151 and Figure 6-152 for existing and proposed improvement sections for North Donahue Drive.

Thach, the main east / west pedestrian route and Donahue, the main north / south vehicular access. In addition, Donahue is a threshold to the athletic core. A pedestrian overpass would reduce the pedestrian and vehicular conflicts, allowing for both types of traffic to be continuous. See Figure 6-156 for existing conditions and Figure 6-157 for proposed solution to relieve the vehicular / pedestrian conflicts.

1

Existing tree canopy is inconsistent. Trees have not been replaced where they have died and been removed.

2

The eastern side of the western stadium parking lot consists of unoccupiable, steep slope with few shade trees. While there is internal north / south pedestrian circulation, east / west pedestrian circulation between the parking lot and the stadium is limited.

3

Existing impervious asphalt parking lot surface doesn’t allow storm water dissipation or filtration before it enters existing storm water inlets. This increases the quantity, pollution and velocity of storm water as it empties into nearby Parkerson Mill Creek. The parking lot provides minimal shade for parked cars and pedestrians and is used to full capacity for special events only.

The northern terminus of Tiger Walk is undefined and requires spectators to gather on steep slopes, areas covered with rock mulch and in existing, unshaded parking lots. This intersection is also a major pedestrian / vehicular conflict zone due to the high amount of north / south traffic along Donahue Drive.

Parking lots at Auburn have seasons that correspond to the athletic calendar - they are not only for parking, but are important to campus culture as prime tailgating locations on game days.

All other times of year, the utility of this lot is reduced to the single function of parking. On days when people depend on trees for shade, this large expanse of asphalt provides little comfort.

This lot also includes the end to the ceremonial Tiger Walk, but is not designed to comfortably support the gathering crowds. See Figure 6-160 for an existing conditions diagram.

Most of the stormwater runoff goes directly into the storm system, taking all of the pollutants

4. 3 SOUTH DONAHUE DRIVE: ARENA PARKING LOT / TIGER WALK TERMINUS Potential Improvements Plan Diagram

1

1

Reinforce existing canopy by filling in gaps in street trees along Donahue Drive.

2

Remove paving, install shaded allee that will create a linear park to improve the pedestrian experience between the Western Thach Concourse and Heisman Drive.

Could serve as gameday tailgating area, potential farmers market location or other special events space.

3

Reduce size of paved parking lot. Replace some existing asphalt with porous concrete. Replace failing pavement and some existing asphalt with reinforced turf or porous paving to allow overflow parking during special events. Locate large shade trees in bioswale parking islands to convey storm water down-slope to a rain garden for filtering and and recharging the groundwater table.

4

Rainwater / water filtration / infiltration garden.

5

Formalize the Northern terminus of Tiger Walk. Reshape the existing slope on the northwest corner of the intersection to allow low, terraced walls that could be used for spectator seating during the Tiger Walk event. Stitch the existing large trees together by creating an arc or circle of trees that would encompass the terminus of the Tiger Walk allowing more gathering space as well as a green / open space adjacent to the new Health and Wellness Center.

6

Reduce pedestrian / vehicular conflicts by providing a grade separated pedestrian crossing where Thach Concourse crosses Donahue Drive.

7

Provide clear pedestrian access from parking area to the Recreation and Wellness Center.

from the parking lot straight into Parkerson Mill Creek. An area as large as the arena parking lot would better serve the campus if it provided more than one year-round use.

With additional rows of canopy trees over grass paving and large rain gardens to filter stormwater runoff, it could provide ecological value as well as become more adaptable to a wider range of campus functions. Not only a park for cars, but a comfortable place for people, whether they are gathering in small groups in the off-season or en masse tailgating before a game. See Figure 6-164 for a diagram displaying these potential improvements.

4.5 DONAHUE DRIVE AT TIGER WALK Currently along Donahue Drive, there is not a continuous pedestrian experience along both sides. As evidenced by Figure 6-169, the single sidewalk is squeezed up against the stadium to the east and absence of any pedestrian path to the west. Replacing the single row of trees to the west with an allee framing a sidewalk would improve the overall pedestrian connectivity of Donahue Drive while also providing additional gathering space for the special event of the Tiger Walk. See Figure 6-168 for a section showing this proposed improvement.

Remove parking spaces on the outside of the arena parking lot to Increase width of area between Donahue Drive and the parking lot to allow for additional shaded gathering space for the Tiger Walk event. Replace existing stone mulch with iconic paving and shade trees in tree grates to enhance the pedestrian experience. Maintain existing trees in this area and intersperse with large new trees of the same species.

Provide shade trees in parking lot and replace impervious paving with pervious paving to decrease pollution and storm water runoff quantities into nearby Parkerson Mill Creek.

Define edges of pedestrian paths and screen parking lot with evergreen hedge.

2

Currently this is the furthest northeast branch of Parkerson Mill Creek that isn’t conveyed in a pipe. Its banks are filled with invasive, non-native species and the channel banks are steep and severely incised. There are multiple exposed utility pipes that cross the channel. It is currently fenced off and inaccessible.

2

3

Contextual new construction does not address this stream section as anything more than something to be piped and it is seen as ‘back of house’ surrounded by utilities and parking.

4

While a few large street trees remain, there are large holes in the existing canopy decreasing the amount of shade available for pedestrians.

5

Existing headwalls are exposed concrete and are penetrated with multiple pipes and other associated infrastructure.

Figure 6-175. This section of PMC has been cleared though additional planting and bank stabilization is needed.

129

3

Decrease the size of the adjacent impervious surfaces by reducing their extents and replacing impervious surfaces with porous surfaces. Install bioswales in parking islands to filter water as it is conveyed toward Parkerson Mill Creek.

Expand the boundaries of this area so the existing stream channel can be widened and restored. Include upslope raingardens to filter and slow runoff from adjacent parking areas. Create occupiable spaces for pedestrians that take advantage of the proximity to water. Include native shade trees and wetland benches for increased habitat and diversity while stabilizing the stream channel banks.

3

Expose (daylight) piped section of Parkerson Mill Creek on the eastern side of Donahue Drive. Locate shade trees along the pedestrian route between the baseball stadium and the new dorms. This area could be used as a park like front yard for the new dorm.

4

Fill gaps in street trees and expand their extents with an allee of trees along the Tiger Walk route.

5

Include a 10’ wide multi-use path connecting the Central Classroom facility, through this site and to a poroposed PMC greenway that would connect central campus to the intramural fields to the south of campus.

Figure 6-176. View down Donahue Drive shows few shade trees

This plan proposes to improve adaptability and ecological function of the creek while creating more comfort for parking lots. It is also important to make Parkerson Mill Creek visible to both vehicular and pedestrian users, celebrating it’s natural functions. See Figure 6-173 for the proposed improvements diagram.

Potential improvements include enhancing ecological function through bioswales and reduced impervious area. Also, by widening and restoring the stream channel with terraced banks and native plants. Create interconnected systems, joining urban ecology and natural systems, to improve the health of the waterway and the pedestrian experience. Make a place out of a ditch, shaping an area for people to experience water and the restored natural system. Reshape topography and create upslope raingardens to allow for more diversity and filtration of runoff before it reaches the stream. Enhance allees where needed along Tiger Walk for continuous shade. Provide a park that bridges Donahue Drive, providing potential for park access to the new dorms to the east and a series of interconnected water spaces to the west.

4.7 SOUTH DONAHUE DRIVE: SOUTH OF SAMFORD DRIVE The outfall of Parkerson Mill creek is a detention basin with no ecological value. The grass is mown to the edge providing no plant diversity and no attraction for wildlife. Also, there are no shaded walks to attract users to the water. The outfall is blocked with sediment from upstream. See Figure 6-179 for a section of the existing conditions and Figure 6-183 for the existing conditions plan diagram.

The potential improvements as shown in Figure 6-180 provide two paths, both shaded. Allees also formalize this stretch of road through campus, highlighting an important route. Improve ecology of stream through a series of forebays and native planting, providing habitat for birds and allowing sediment to be trapped. Improve the ecology and appearance of the stream with native plants and healthy water.

Existing pedestrian pathway on east side of road lacks shade and there is no pedestrian pathway on the western side of the road.

2 3

The upstream section of the Parkerson Mill Creek tributary is very incised and has little or no stream bank stabilization available. The current headwall and pipes are basic concrete and in poor repair.

There is no forebay to contain sediment coming from sources upstream. Therefore the channel leading to the pond is choked with sediment. The channel is lined with riprap and the pond edges are mown to the water surface resulting in a lack of diversity in the edge condition.

Add pedestrian path to the Western side of Donahue Drive. Add allee of shade trees on either side of the road to provide shaded walk for pedestrians.

2

Restore the existing stream channel and reinforce with native understory planting. Clad headwalls with brick to match the material language employed elsewhere on campus.

3

Install weir walls downstream of the outfall to create forebays that will catch sediment suspended in the water and allow it to settle before entering the pond. Plant hydric species of low maintenance, native vegetation around pond edge to encourage diversity and filter water as it flows into the pond. Native species of hydric trees will help to stabilize the pond edge.

1

Tributary of Parkerson Mill Creek is very incised upstream and downstream of the pond. The adjacent Forestry Building was located too close to the existing incised stream. The resulting erosion has been poorly stabilized by spreading out rip rap and covering it with loosely placed concrete.

2

The current headwall is exposed concrete and rip rap. Views of this structure detract from the experience of the park.

3

The existing traffic table / crosswalk does not connect sidewalks. It covers a drainage pipe and connects one area of rip rap to another creating a confusing pedestrian conflict.

4

The existing pond edge is mown to the water surface leaving the edge condition without diversity.

5

The stream outfall into the pond is heavily silted and clogged with sediment. There is no forebay to capture sediment allowing it to build up on the upstream side of the pond forcing incoming water to change course and scour the banks of the stream channel.

6

The dilapidated asphalt road is a remnant and does not connect anything on site.

The Agricultural Heritage Park is a place where the agricultural and land grant heritage of the entire university can be celebrated. It is also a big campus landscape with adjacencies to many other campus landscapes, the stream ecosystem of Parkerson Mill Creek, forest remnants and open agricultural fields. This intersection of agricultural, cultural and natural landscapes is a unique moment on campus, but is a common occurrence in large scale agricultural ecologies. As such, it offers an opportunity to demonstrate best practices for integrating agricultural systems with natural systems in a sustainable and beautiful way that supports the function of the agricultural production while enhancing the quality of the natural ecosystems. See Figure 6-188 for potential improvements.

In doing so, the park should be developed to define the structure and borders of these different landscape types, rendering the connections and relationships between them more legible.

Existing unshaded grass fields and gravel / asphalt parking areas are uncomfortable for people to occupy during special events like gameday gatherings and farmer’s markets.

1

Restore Parkerson Mill Creek channel. Widen it so that it can contain peak flows. Plant the banks with native, hydric species to stabilize the soil. Locate a pedestrian path adjacent to the restored channel to connect the Hill Dorms, Ag Heritage Park and the intermural sports fields.

2

Clad the headwall with brick to tie it into the contextual materiality.

3

Extend the traffic table / crosswalk to the west so pedestrians can access the parking area.

4

Plant large, native, low maintenance shade trees to form a shaded grove around the pond edge. Use native, low maintenance shrubs and ground covers to stabilize the edge. Filter water before it enters the pond and focus access to the waters edge to spaces where that is intended.

5

Install weirs to create a forebay to collect sediment before it enters the pond. This area should be heavily planted at the ground plane to slow incoming stormwater flows and help filter water before it enters the pond.

6

Remove the asphalt road and associated fence to allow for additional screen planting.

7

Expand the boundary of the existing remnant forest to increase habitat and diversity. Provide wildlife corridor connection to adjacent remnant forest on the east side of Donahue Drive.

8

Replace missing street trees so that size and spacing are consistent along Donahue Drive and Lem Morrison.

9

Locate demonstration agricultural fields here to bring the land grant agricultural heritage of the university closer to the campus core.

10

Replace gravel and asphalt parking areas with reinforced turf to allow storm water infiltration and overflow parking during special events.

Provide shaded grove for gameday parking of RVs and cars. Area should feel like a shaded park, not a field.

5.1 MAGNOLIA AVENUE: MAGNOLIA AVENUE CROSSWALKS Pedestrian connections between the Auburn campus and the adjacent community are the paths along which people entering Auburn first orient themselves to the campus. As such, they should be clear, highly visible and well lit, aligned with campus destinations and of a consistent material.

The existing crossings along Magnolia lack consistency having one or more of these characteristics; poor visibility, multiple materials, multiple alignments, and lack of shade. See Figures 6-199 through 6-204 for existing conditions at various crossings along Magnolia Avenue. These crossings should be unified under the campus-wide standards adopted for all pedestrian thresholds to campus. See

Section VI: Landscape Standards for the Extended Campus Core.

Crossings should be aligned with other sidewalks when possible to increase legibility and continuity of the pedestrian network. As thresholds to campus and gateways that often serve as meeting places, they should be shaded and comfortable, adding canopy trees where possible to offer comfort and further improve the visibility of the campus entrances. See Figures 6-205 through 6-210 to see how these ideas can be applied to the various Magnolia Avenue connections.

Bollards are overwhelming in the landscape and are used too frequently.

Figure 6-219. Groundplane lacks interest and diversity

Turf is the predominant ground plane planting currently installed on campus. Although turf can be a very useful surface, providing occupiable and adaptable outdoor space, it has little ecological value, requires regular maintenance, mowing, the use of fertilizers and is only marginally more effective than asphalt or concrete in managing stormwater. In locations such as eastern Magnolia Avenue, where the areas of turf are not appropriate for gathering, it is recommended to transition the groundcover from turf to low-mow (and low-maintenance) native grasses and native shrubs.

Once established, this plant regime requires significantly less maintenance in terms of mowing, irrigation and fertilization. Along eastern Magnolia Avenue, it is also recommended to provide occupiable shade along the walks by planting parallel rows of mature canopy trees. See Figures 6-216 and 6-217 for sections along eastern Magnolia Avenue which represent these existing conditions and potential improvements.

1 As lawn spaces along the primary pedestrian spine of campus, this series of greens is potentially useful as gathering spaces, although the existing lack of shade and/or inaccessible shade discourages gathering (see Figure 6-234). Adding accessible shade to these greens is the primary goal for future improvements (see Figure 6-235), through the addition of mature canopy trees. Also, clearing out the shrub layer is necessary to allow for pedestrian connectivity under trees. Framing both spaces with rows and allees of mature canopy trees will provide occupiable shade at the edges and open interiors adaptable as informal gathering areas.

Existing infrastructure (lights, bollards, adjacent sidewalks) are scaled for a vehicular street and are not suited for the current use.

Although it has been closed to vehicular traffic, the material and scale of this section is more indicative of a space for vehicles than of a comfortable and useful space for pedestrians (see Figures 6-241, 6-242 and 6-243). See Figure 6-239 for an existing cross section through the corridor. Replacing the asphalt with porous pavers and adding rows of mature canopy trees would continue to improve it as a pedestrian corridor, distinguish spaces for foot and bicycle transit and provide a sense of continuity with the rest of Thach Concourse.

Utilities are poorly located and very visible to pedestrians.

1 The general layout of Arena Plaza works well to connect Thach Concourse to the numerous athletic destinations to the south, although the visibility of the arena entrance and hierarchy of paths could be more clear by reinforcing them with planting. New planting of canopy trees would distinguish main paths from clearings and secondary paths, adding structure, legibility and comfort to the path network. See Figures 6-244 and 6-245 for before and after diagrams of the Arena Plaza space.

The Thach pedestrian corridor is at its widest between the Village dorms, although the usable space is currently concentrated on the paved concourse. See Figure 3-244 and 3-245 for views down the open corridor. If the concourse is defined as the entire space between building facades, there are multiple opportunities to develop interstitial spaces for gathering, study and play. This approach can redefine this pedestrian space on campus, developing it as a vibrant urban boulevard with a transit core layered with diverse outdoor spaces for student life. The expansive section also provides underground opportunities for harvesting rain water to irrigate the expanded landscape.

The existing and proposed improvements are highlighted by typical sections in Figures 3-242 and 3-243.

As this terminus / beginning of Thach Concourse is solely pedestrian, the visibility of this entrance as well as connections to the wider campus pedestrian network should be improved. To help achieve better legibility, the distinctive arc path should be emphasized with mature canopy trees (see Figures 6-254 and 6-255). Crossings should be formalized to improve pedestrian safety and wayfinding. See Figures 6-252 and 6-253 for existing and potential treatments of the intersection.

6.7 THACH AVENUE AND CONCOURSE: WESTERN THACH PARKING Existing Conditions

Large amounts of impervious asphalt prevent water from filtering or dispersing prior to being directed into adjacent branch of PMC.

2

Parking islands contain areas of mown grass with undersized trees that provide little or no shade.

3

Existing branch of PMC is heavily incised and lacks diversity. There is no planted buffer or bank reinforcement.

The western Thach Concourse parking area is one of the largest surface parking lots on campus. This expanse of impervious pavement lies adjacent to a branch of Parkerson Mill Creek. It currently sheds all its water into the storm system without filtration of pollutants. This process contributes to the volume of peak water flows and the pollution of the hydrologic network. See Figure 6-256 for a view of the existing conditions at the western Thach Concourse lot.

1 Potential improvements for the parking area are shown in Figure 6-257.

Updated with permeable paving and graded to filter water through rain gardens before discharge into PMC, this lot can be updated to improve rather than degrade the quality of PMC without sacrificing its utility.

7.1 PARKERSON MILL CREEK: NEAR WESTERN THACH PARKING In general, the stream corridors of Parkerson Mill Creek have largely been ignored and neglected. As a series of corridors that travels north / south and also east / west, the stream infrastructure could play a huge part in developing a continuous pedestrian network throughout the core campus. This northwest section (see Figure 6-266) is characterized by an understory choked with non-native invasive species and an incised and eroded stream channel, likely due in part to the volume of runoff from the adjacent parking. It is also one of the few places with an intact grove of trees, providing an opportunity to restore the forest ecology. By managing this forest / stream corridor for invasive species, restoring the stream and replanting with native species (see Figure 6-267), these ecosystems could be restored while also creating restful restorative environments for the campus community. Figures 6-268 through 6-271 highlight some of the current stream conditions near the western Thach Concourse parking area.

Auburn University Landscape Master Plan, Comprehensive Campus Master Plan Update 2014

7. 2 PARKERSON MILL CREEK: AT OLD FRATERNITY HOUSE SITE This section of PMC is little more than a ditch between two culverts (see Figures 6-274 and 6-275). Although there are a few trees, this existing condition is more like a piped stream than a functioning ecosystem, designed for quick transport of water offsite and downstream.

Expanding the stream channel and restoring the landscape as a forest/floodplain ecosystem will not only create an attractive pedestrian oriented space, but slow the water at the headwaters of this branch, improving the water quality before it heads downstream. See Figure 6-273 for a section showing the potential improvements.

Existing Conditions

1

Existing stream channel is incised where it isn’t contained in the existing culvert (remnant of the old fraternity house foundation)

2

1

Construct forebay with weir wall to contain sediments before they flow downstream. Regrade existing stream channel to provide flood plains on either side for increased stormwater flow capacity.

2

In place of turf, plant low maintenance, native groundcovers and shrubs along stream corridor to serve as buffer and filter water before it enters the stream.

3

Remove invasive species from existing forest and introduce / encourage native species of understory planting.

4

Provide walking, jogging and biking trails to increase use of the shady green corridor.

7. 3 PARKERSON MILL CREEK: NEAR CDV PARKING This is one of the most incised sections of PMC (see Figure 6-276). Due to discharge from adjacent parking, the stream channel is characterized by steep and deeply eroded banks. It is overgrown with a stand of forest which is physically and visually impenetrable. A series of proposed improvements (see Figure 6-277) would reconfigure the parking lot and slope to demonstrate how urban ecologies can link with natural systems. First, provide permeable paving at the parking lot to infiltrate more water. Then provide a raingarden to filter any remaining runoff. Stabilize the banks with terracing and native plants. Also, widen the stream channel so that it may function more naturally. Finally, create pedestrian paths throughout so that the restored ecologies can be experienced.

Existing Conditions

1

Existing stream channel is incised and contains construction debris and trash.

2

Existing asphalt parking lot drains directly into stream channel with no opportunity for filtration.

The restoration of PMC in this location would involve the removal of fencing to open up views and physical access to the adjacent athletic fields, potentially providing east/west connectivity across the athletic core which is currently divided by the creek corridor. Where the available land for stream restoration is too narrow to install a proper flood plain the stream could be narrowed and use weirs to navigate the elevation difference while reducing water velocity.

8.1 BIBB GRAVES AMPHITHEATRE Graves Amphitheater is one of the iconic landscapes on campus. Figure 6-304 shows a view across the shaded amphitheater. Over time, the amphitheater’s remote location and lack of regional connectivity have contributed to reduced awareness of this space. Campus development has generally focused on the urban core and has left this space off the beaten path. Figure 6-306 diagrams some existing conditions which detract from the space. Figure 6-307 offers suggestions on how the amphitheater can once again become activated. With the introduction of important classroom developments adjacent to the amphitheater, pedestrian networks can connect this space with more potential users.

The intersection at Duncan Drive and Samford Avenue signifies a clear transition from the northeast urban core to the southeast “big landscapes” zone of campus. Thus, the intersection offers another opportunity to better define campus regions with wayfinding signage. The existing column structures (see figure 6-305) are out of scale for this location and are therefore ineffective.

The intersection will increase in importance as the new STEM Building reaches completion. This too will bring an increase in vehicular and pedestrian traffic. The functionality of the intersection in terms of wayfinding legibility, pedestrian connectivity and vehicular management must increase proportionally as well.

This corridor prioritizes vehicular traffic with the pedestrian experience defined by a single wide expanse of concrete on one side of the road (see Figure 6-310). For the majority of its length, it is adjacent to parallel parking and traffic with no buffer between. By reducing the width of the pathway, shifting the path away from the street and adding a landscape strip between, Duncan Drive could accommodate both vehicular and comfortable, shaded pedestrian walks.

2

The area between Duncan Drive and Leischuck Hall Dorm illustrates a typical structure placed “on” the landscape rather than “within” the landscape (see Figure 6-311). Minimal planting around the building’s foundation do little to soften the transition from site to structure. This also creates a high maintenance area through the excessive use of turf. Replacing these turf areas with Low-maintenance native shrub and tree beds and increasing foundation planting around the building would significantly reduce maintenance, increase building aesthetic and create a more pedestrian friendly environment.

8.4 DUNCAN DRIVE AND P.O. DAVIS DRIVE INTERSECTION A piped tributary of Parkerson Mill Creek daylights at this location. Restoration and expansion of the creek is restricted due to development near the Forestry Building and the layout of the Patterson Greenhouses.

A constructed method of streambank restoration is recommended. Reinforce the expanded creek terraces with naturalized walls to stabilize the banks and help prevent erosion. In addition, utilize the creek-wide strategy of restoring native plant communities and adding pedestrian use areas and paths.

There is no clear pedestrian crossing currently offered at the intersection. A clearly delineated crosswalk should extend, from the primary dorm walkway on the north side of the parking areas, across Duncan Drive. The walkway which currently runs parallel along the west side of Duncan Drive should be extended to meet this point. See Figure 6-314 for an aerial view of the intersection at Duncan Drive and P.O.

As a spur connector between Lem Morrison Drive and Duncan Drive, P.O. Davis Drive caters to vehicular traffic (see figure 6-316). Only a small section of sidewalk exists at the eastern end of P.O. Davis Drive. The pedestrian experience is defined by parallel parking on both sides of the road against a double bay parking area. Landscape medians between the two are compacted and eroded leading to significant decline in the health of the trees within the median (see figures 6-318 and 6-319).

9.1 WIRE ROAD AND HEISMAN DRIVE INTERSECTION

9. 2 WIRE ROAD PEDESTRIAN IMPROVEMENTS

Many University users approach the campus from it’s western boundary via Wire Road. One important node along Wire Road occurs at the Heisman Drive intersection. This intersection defines the transition point for Wire Road’s two distinct character zones. The stretch along the campus core and it’s southwest extension which escorts traffic away from the heart of Auburn. The Heisman Drive intersection allows vehicular and pedestrian traffic to cut east into campus.

Despite it’s role as the major thoroughfare along the western side of campus, Wire Road is currently defined by its openness and lack of pedestrian connectivity (see Figure 6-324). The corridor is generally geared to vehicular use, except between Samford Avenue and Webster Road where bicycle facilities were recently added. In addition, the long row of bollards bordering its pavement demand a strict point to point travel plan for users. Wire Road has the opportunity to become an important pedestrian and bicycle corridor as it connects so many important nodes along western campus.

This intersections role as an important node needs to be better defined. Vegetation can be used to accent the intersection’s role as a core campus boundary. Specifying certain street tree species on either side of the transition can assist with this notion. In addition, clear demarcation of the pedestrian connections should be made. A paving system can provide clear contrast from the asphalt. See the Figures 6-321 and 6-322 below for some potential improvements that could be made at this hub.

A view down the corridor shows the potential for pedestrian connections.

Wire Road’s openness is not inhibited by many roadside obstacles allowing sufficient room for a multi-use path. A landscape area between the path and the vehicular travel lanes will provide added comfort to pedestrian users. Shade trees planted along the corridor will help define the roadway system, relieving the openness (see Figure 6-325). These trees will also provide shade for the multi-use path and encourage activity throughout the hotter months. Trees planted here will need to be coordinated to avoid conflicts with adjacent utilities above and below ground. Refer to the utility guidelines in Section 4: Landscape Standards.

Figure 6-324. View down Wire Road showing lack of pedestrian connectivity

As shown in the Heisman Drive intersection graphics, pedestrian crossings can be improved to better define connection points. A typical paving system, as defined in section 4: Landscape Standards, can be utilized at all Wire Road intersections to improve the pedestrian usability along this corridor.

Design Recommendations - Corridors

To better improve the aesthetic of this corridor, the bollards should be removed and replaced with strategic landscape planting. The bollards are in place to restrict vehicles on game days, a mere seven weekends of the year. This negative impact on the campus aesthetic; however, is year round. The planting will perform the role of restricting gameday parking while contributing to the campus aesthetic year round.

Turn lane is under utilized and has potential for reduction of impervious surface.

Samford Avenue is a major east / west connector that bisects the Auburn University campus between South College Avenue and Shug Jordan Parkway creating three distinct sectors. The western sector (see figures 6-328 and 6-329) between Wire Road and Shug Jordan Parkway is the most ‘rural� of the sectors. It is characterized by clear cut wooded edges, an underutilized center lane and redundant pavement (multi-use path directly adjacent to an on road bike lane, see figure 6-331). Vehicular traffic in this area flows at greater speeds than other sectors of Samford Avenue with little or no separation between vehicular and pedestrian uses. Improvements to this sector include reducing impervious surface and providing separation between vehicular and pedestrian uses by slowing traffic by converting the turn lane into a landscaped median with deceleration center lanes at key points, and increasing biodiversity by utilizing a diverse palette of native species planting at woodland edges and within the landscaped medians and strips.

Clear cut wooded edges lack ecotone transition which is key to biodiversity of woodland edge species.

10. 2 SAMFORD AVENUE CENTRAL SECTION The sector of Samford Avenue between South Donahue and Wire Road passes through the southern end of the “athletics core”. Similar to the western sector, the central sector exhibits an excessive amount of pavement with an underutilized turn lane and multi-use path directly adjacent to on-road bike lane. Pedestrian paths are uninviting and uncomfortable due to the absence of shade and destination (crosswalk exists but does not lead to another pathway). Also, mid-block crossings create dangerous conflicts between vehicular and pedestrian traffic on this corridor. Mid-block crossings should be eliminated and pedestrian crossings should be re-routed to signalized intersections. In addition, there are some missed opportunities to help improve ecological performance. Improvements include reducing pavement by converting the turn lane into landscaped medians with turns at key points, utilizing slopes as functional spaces by adding native shrubs and trees to help slow runoff and adding raingardens at the toe of these slopes to help filter storm water, replacing or planting larger species of trees to help shade pedestrian pathway and assuring access from crosswalks. See Figures 6-336 and 6-337 for sections highlighting existing conditions and some potential improvements.

Auburn University Landscape Master Plan, Comprehensive Campus Master Plan Update 2014

10. 3 SAMFORD AVENUE EAST SECTION The eastern sector of Samford Avenue, from South College Avenue to South Donahue Drive, is sandwiched between a student residential area (Hill Dorms) and classroom buildings. There is a significant amount of back and forth pedestrian traffic as well as vehicular traffic. While vehicular needs such as parking are at a premium, they should not diminish the residential atmosphere.

Minimal tree and landscape planting lessens the “residential� nature of the sector. See Figure 6-338 for these existing features.

Potential improvements include reducing pavement by eliminating parallel parking in front of dorms, decreasing the width of the excessively wide path to accommodate a widened planting area between Samford Avenue and the parking area, and providing larger planting areas in front of the dorms. Figure 6-339 offers a view of these potential improvements in place.

Future improvements per the Master Plan include the Health Science Sector to the southwest and a recreational fields expansion to the southeast

Figure 6-347. Lem Morrison Drive and Donahue Drive Intersection Source: MapData: Google

Lem Morrison Drive and Donahue Drive intersection (Figure 6-347) is a significant pedestrian / vehicular threshold although there is nothing that distinguishes it as such. The four corners of the intersection do little to help define it with student / gameday parking / tailgating located on three corners and the fourth corner being a wooded lot. However, with the future Health Science Sector proposed for the southwest corner lot and the recreation fields expansion proposed for the southeast lot, the importance of this intersection will greatly increase in the near future.

The pedestrian connections currently exist only through crosswalks located within the intersection. Pedestrian crossing signalization is also absent at the intersection. Improvements to the pedestrian experience should include pedestrian signalization and the extension of walkways in all directions. This includes extending pathways in both east and west directions along Lem Morrison Drive. It also includes providing sidewalks on the north side of Donahue Drive, and a multi-use path to the south.

Additionally, wayfinding signage should be located at the intersection to announce it as an internal threshold.

Proposed improvements to the parking areas would reconfigure the parking lots in a series of landscape spaces to take advantage of the ecological system. Permeable paving or grass paving would replace dirt lots to help infiltrate more water and reduce erosion, raingardens could be installed to help filter runoff and rows of canopy trees would provide shade. These parking areas could then function as gathering areas during the athletic season or function with a park like atmosphere during the off season.

See Figures 6-343 and 6-344 for diagrams on existing conditions and potential improvements.

Auburn University Landscape Master Plan, Comprehensive Campus Master Plan Update 2014

Existing conditions and potential improvements for Lem Morrison Drive are highlighted in Figures 6-348 and 6-349. Currently, Lem Morrison Drive is lacking a continuous pedestrian experience along both sides of the road.

This is evidenced by the absence of pedestrian paths from Biggio Road to Duncan Drive. Providing a multi-use trail on the north side of the road to tie into the multi-use path at Donahue Drive and Lem Morrision Drive, and a pedestrian sidewalk on the south side of the road with a repetition of shade trees on either side, would improve the overall pedestrian connectivity of Lem Morrison Drive.

Additionally, existing concrete swales on either side of the road collect and quickly carry storm water away from the road but leave little option for infiltration (see Figure 6-350). Replacing the concrete swales with vegetated swales filled with native species would slow down storm water runoff and allow for it to be filtered prior to being discharged back into Parkerson Mill Creek (Figure 6-351). These improvements should adjust as needed due to spatial limitations at the creek crossing and west of Biggio Drive.

12.1 BIGGIO DRIVE

12. 2 HEMLOCK DRIVE

Predominantly in full sun, the southern sector of Biggio Drive is an area that sees substantial pedestrian traffic due to the location of the intramural fields, yet there is no pedestrian connectivity. Users either utilize the unshaded parking area or create cow paths along the perimeter of the intramural fields to get to their destinations. These existing conditions are represented in Figure 6-356.

Hemlock Drive acts as an important north / south connection between Magnolia Avenue and Samford Avenue. This corridor is predominantly utilized by residents and visitors of New Fraternity Row and University Housing. Also notable, Parkerson Mill Creek branches out around Hemlock. With the proper restoration of PMC’s banks (see Figure 6-361), this area can be highlighted to increase interest along the Hemlock Drive corridor.

Recommended improvements are shown in Figure 6-357. First, provide pedestrian pathways on both sides of the road.

Next, vegetate the turf areas near the parking lot with native trees and shrubs. This will help direct pedestrian traffic and minimize erosion and runoff. Finally, provide parking islands with large shade trees per Section VI: Landscape Standards for the Extended Core Area. This will help minimize the heat island effect within the parking area and improve aesthetics.

Pedestrian connections are lacking along Hemlock Drive (see Figure 6-362). The introduction of formal multi-use pathways would encourage walking from the residences to the campus via Hemlock Drive.

12. 3 HEISMAN DRIVE Heisman Drive is generally a well defined and highly used corridor. The addition of shade trees and landscape buffers to separate pedestrian and vehicular spaces should be included during future improvements. Existing trees should be allowed to mature and given extra care to provide a closed canopy along pedestrian walkways.

Recommendations also include a transition of the groundcover from turf to low-maintenance, native grasses and shrubs. See Figures 6-363 and 6-364 for sections showcasing these recommendations.

Predominately in full sun, War Eagle Way lacks comfortable pedestrian walking areas. However, there have been extensive shade tree plantings in the past seven years, so this will continue to improve as these plantings mature.

Walks are directly adjacent to vehicular and transit lanes (see Figure 6-372) and display an absence of shade and small gathering areas. Improvements include separating vehicular and pedestrian spaces by creating vegetated buffers, taking advantage of wider lawn expanses to create inviting gathering areas and softening hard surfaces (such as building facades) with native landscape materials. Figures 6-369 and 6-370 show potential improvements in relation to existing conditions for War Eagle Way. The intersection of War Eagle Way and Wire Road has been identified as a problem for buses. Currently, the intersection does not provide the adequate turning radius space for Tiger Transit to make the turning movement while cars are stopped at the stop sign. The corner radius should be expanded to relieve this conflict.

INTRODUCTION A series of focus areas was selected for greater in-depth analysis and to further illustrate recommendations for future campus landscape design and development.

Detailed plans for these areas provide recommendations for future improvements along with a better understanding of how the Campus Landscape Master Plan landscape vision and guidelines are to be applied at the project level. These focus area plans also offer the University a tool against which they can evaluate future design proposals. The focus areas include: Thach Concourse, Samford Park, the Academic Success Center and Parkerson Mill Creek (see Figure 6b-1).

Samford Park is the front door to campus and includes iconic elements at Toomer’s Corner and Samford Hall. Currently the park denies access to available open spaces and shaded seating with the overuse of understory planting along pathways. The proposed solution opens up the ground plane to encourage students to embrace and more actively utilize this front campus gem.

The Academic Success Center will ultimately provide much needed classroom space at the southern edge of the campus’s urban core. This development will bring with it many exciting landscape vision opportunities including the potential to restore natural ecological processes to the campus core. This focus area plan reintroduces Parkerson Mill Creek and its hydrologic processes as a celebrated centerpiece of the proposed facilities.

Parkerson Mill Creek existed in this place long before there was an Auburn University.

It is an important natural system which has been severely degraded over the years.

Fortunately, the University now recognizes its value and plans to preserve, protect and enhance it in coming years.

To further demonstrate the importance of returning the Parkerson Mill Creek corridor as a central feature on campus, a portion of Parkerson Mill Creek has been analyzed on a focus area level. This area highlights how a key stretch of Parkerson Mill Creek, near the intersection of Biggio Drive and Samford Avenue, can be modified to create a restored stream with nearby park and trail features.

Thach Concourse acts as the major East/West pedestrian corridor connecting much of the campuses urban core. Recently closed to vehicular travel, this portion of the concourse is lacking in pedestrian friendly design amenities. The concourse currently exhibits an absence of shade, a large amount of impervious surfaces, a lack of clear definition of the promenade, and a shortage of comfortable gathering spaces. Potential improvements to the concourse include the introduction of stormwater management systems, shade trees to define the path and a series of gathering spaces along the corridor.

Create raised traffic table at the vehicular intersection to slow vehicles down and herald the gateway to the University. This will stitch the university together with the downtown and allow pedestrians to pass more easily between the two areas. This could also incorporate a gateway arch over the road that could be used to ‘roll’ during celebrations.

2

Widened area along path paved in Type ‘A’ - Special Paving - Granite with specialty benches that could offer donor or memorial opportunities as well as defining areas to sit for special events. Refer to Section 4: Landscape Standards.

3

A 15’ wide arcing path paved in brick with granite banding defines the main path from Toomer’s Corner through Samford Park to Thach Avenue. This path should be lined with stately native trees (single species) such as Quercus phellos or Quercus virginiana. These trees should be installed at a significant size (6” cal. or greater) so their impact is more immediate.

4

Existing path should be removed in this area to place emphasis on the main entry points into Samford Park. The understory should be free of shrubs and groundcover and consisting of a durable turf grass such as Tifway 419 Bermuda or Emerald Zoysia so that users can take advantage of existing and proposed shade trees.

5

Access to College Street along the length of the path should be limited and consolidated into one accessible crossing that aligns with the Langdon Hall Courtyard. This crossing should be a Type ‘B’ Paved Crossing and have clear pedestrian crossing signs, signals and traffic calming paving such as brick banding. This crossing should align with the center line of Langdon Hall.

6

Secondary paths to and from the main arcing path should be Type ‘C’ - Concrete with Brick Bands.

These paths should have clear directionality to make wayfinding for pedestrians obvious. They should have specialty benches placed along for pedestrians to sit and enjoy shade provided from existing and proposed trees. These benches could also provide donor or memorial naming opportunities.

7

The existing lawn should be formalized and made symmetrical by adjacent framing paths. This lawn will be free of shrubs and groundcover to allow pedestrians access to shade. The paths defining the central lawn should be moved so that they align with the front doors of Samford Hall and are perpendicular to College Street. The northern most path should align with the front door of O.D. Smith Hall.

8

A significant ‘heritage’ planting should be located where the main arcing path diverges to head east and west along Thach Avenue.

9

Smaller, separate courtyards created by adjacent buildings should be tree lined and offer shaded gathering spaces. These areas should be largely turf and accessible from adjacent pathways for special events and daily use by students and faculty.

Detail Focus Areas

10

The space between Samford Hall and Langdon Hall offers opportunity for a memorial walk that connects Samford Park to Ross Square. This area should be more heavily planted with a few species of medium sized flowering shrubs such as Hydrangea quercifolia, Itea virginica, and Aesculus parviflora to create a defined, fragrant, beautiful walkway. The historic lathe sets a precedent for marking historical events in this area.

11

The plaza in front of Samford Hall should be paved with Type ‘A’ - Special Paving - Granite to create a defined space for special events.

12

Large existing trees should be protected and remain.

13

The area directly adjacent to Samford Hall should be planted in medium sized shrubs and groundcovers to mask the base of the building and provide a foreground. This will also help keep pedestrians away from the base of the structure and adjacent windows. Any lighting of Samford Hall should happen from this planted area so that the planting can screen the lights from view during the daytime.

Create a clear main path through the park that connects the Corner at Toomer’s through the park towards Thach Ave. This path should have a high material finish like brick with granite banding or similar. Large, shade providing trees should be planted in an allee to create a memorable, cloistered walk.

3

Arcing the path further to the north opens up more lawn for use and creates a defined foreground for Samford Hall. This arcing path defines the edge between the formal lawn and the informal planting beds and adjacent gathering spaces.

Straighten Haley Concourse between the Student Center and the ASC complex. The south end of this section of concourse forms an intersection between the ASC courtyard entrance to the south, the Tiger Lawn to the west and the historic Quads / Roosevelt Concourse to the east. This section of concourse should be paved with Type ‘B’ - Decorative Brick and be lined on the sides with standard benches. Trees should be planted at a large enough size at installation to create instant shade (6” cal.+) and be a single species of shade tree like Quercus alba or Fraxinus pennsylvanica.

2

Graded bowl provides elevational transition between the intersection of the concourses to the north and the ASC courtyard to the south. The grade transition in this area allows the existing Duggar Concourse to remain in its current location by using the eastern side of the proposed eastern building to retain grade.

This area would consist of a durable turf grass such as Tifway 419 Bermuda or Emerald Zoysia and provide informal gathering space as well as outdoor classroom space.

3

An arcing path provides an accessible route to the ASC courtyard while defining the northern edge of the graded, turf bowl. This path would be paved with Type ‘C’ - Concrete with Brick Bands. This path creates the northern most end of what eventually turns into the Parkerson Mill Creek Greenway Trail.

4

Steps that provide pedestrian access along the north side of the building would be concrete risers with brick treads. These steps would be lighted by recessed lighting from the adjacent building and separated into separate sets of risers no more than 5 risers tall so as to not require handrails.

5

The courtyard / entrance for the eastern building would be paved with Type ‘B’ - Decorative Brick and would contain shade trees in grates flush with adjacent pavement. Non-fixed seating would be placed in this courtyard to accommodate students coming and going from classes as well as informal areas for gathering, studying and socializing. This courtyard would be flanked by teaching gardens on the north and west that would be terraced and structured by faculty to describe the process of water filtration and conveyance.

6

The stairs that provide direct access from the concourse intersection to the main ASC courtyard would be a combination of brick and granite and would be illuminated by recessed lighting based in framing cheek walls. These cheek walls would be brick clad with granite caps. Adjacent to these steps would be a small outdoor amphitheater framed by the stair tower of the building. The seating for this amphitheater would be the same material as the adjacent stairs and should appear as they are connected.

7

A forebay collects the water at the outfall of the culverted Parkerson Mill Creek to filter out sediment and trash before it enters the main section of the pond. This forebay is contained by a weir that keeps the water elevation in the forebay approximately 8” higher than the elevation of the main pond. This also serves as a pedestrian path connecting the north and south edges of the pond.

The main pond stores and slows water during storm events and protects the downstream section of Parkerson Mill Creek from scouring and erosion. This pond also provides a peaceful setting around which to walk, gather, sit, converse, study, dine and be in nature.

9

A terraced courtyard provides an accessible route to the building entrance while offering shaded, grade separated rooms for students and faculty to study, dine and gather in. These terraces would contain grids of mid-canopy shade trees such as Lagerstroemia, Cornus florida, or Acer buergeranium with non-fixed seating and tables for informal gathering by groups of varying scales. The terraces would be supported by brick clad walls with granite caps.

10

A pedestrian bridge connects the courtyard to the beginning of the Parkerson Mill Creek Greenway Trail.

This bridge would be light in its structure, possibly steel with timber decking and a stainless steel guardrail.

11

An informal, meandering path with Type ‘D’ - Concrete Paving, would connect the eastern courtyard to the Parkerson Mill Creek Greenway Trail. This path would be bordered with medium sized shade loving trees and shrubs such as Hydrangea, Aesculus, Magnolia stellata, Betula nigra and Cornus florida. This edge of the pond would be more wild and natural while the opposite side (adjacent to the building) would be more urban and constructed.

12

The building entrance plaza would be paved with Type ‘A’ - Special Paving - Granite and would have a guardrail along the pond edge to match that used on the bridge. The paving from this entrance plaza would carry through to the terraced courtyard.

13

The beginning of the Parkerson Mill Creek Greenway Trail would be paved in Type ‘D’ - Concrete Paving and would be lined with mid-canopy tree species that tie into what is used in the courtyard. This path would have informal benches at regular intervals along its length.

Parkerson Mill Creek is in a culvert behind Parker / Allison Hall. This culverted section of the creek results in high velocity outflows where the culvert discharges near Biggio Drive.

Removing the parking along Graves Drive allows for a more natural, shaded walkway that connects users from Duggar Concourse through the courtyard of the new ASC complex to the proposed Parkerson Mill Creek Greenway Trail.

2

By daylighting Parkerson Mill Creek and impounding the water to create a pond, velocities at the outfall are reduced and a forebay is created that will help improve water quality and quantity. In addition to improving the health and viability of Parkerson Mill Creek, the proposed pond creates a new amenity and focal point for the campus.

3

By using the proposed ASC building to retain grade adjacent to Tiger Lawn, a space on the south side of the proposed building is created that allows use by pedestrians. This space would be shaded by groves of understory trees and terraced to provide an accessible route to the proposed pond’s edge.

1

Removing the gravel contractor lay down area at the eastern side of Biggio Drive and moving Biggio Drive to the west would allow room to provide a restored creek section and Parkerson Mill Creek Greenway trail that connects to the intramural fields and agrarian landscape beyond.

2

An informal greenway trail could connect the proposed CCF facility, new recreation facility and the urban campus core to the intramural fields. This path could be crushed stone and would follow the restored grade of the creek. This edge would be more natural in character and would be flanked by native, hydric plant and tree species.

3

Creating a series of check dams or weirs along the length of Parkerson Mill Creek would help reduce the amount of scouring as a result of storm events and would provide a controlled method of discharging storm flows downstream. These weirs could be clad in stone and would have several levels of outfalls including normal pool, and storm flow sizing.

4

A realigned Biggio Drive on the south side of Lem Morrison Drive allows space for stormwater gardens to be created on either side of the drive. These gardens would capture runoff from the adjacent gymnastics parking lot as well as a proposed intramural parking lot on the south side of Biggio Drive. These gardens would filter and slow runoff before it enters Parkerson Mill Creek, therefore improving the water quality and reducing the potential for erosion. These gardens would be planted with hydric species such as Quercus bicolor, Cyrilla racemiflora, Iris, and Asclepias tuberosa.

5

A bridge crossing the restored Parkerson Mill Creek would be light in construction and not require major earthwork or disruption during installation. This bridge could be prefabricated, constructed of steel and have a timber deck and top rails.

6

A renovated parking lot at the gymnastics building would be constructed to accommodate the realignment of Biggio Drive. This parking lot would retain the current number of parking spaces and would grade the parking lot to drain to the southeast toward the proposed stormwater gardens. Paths that bring users from the parking lots to the gymnastics building would be a porus Type ‘D’ - Concrete paving and would guide visitors through shaded parking islands towards the building.

7

A proposed parking area for the intramural fields is able to be created by the realignment of Biggio Drive.

This parking area would be similar to the gymnastics parking lot in that it would slope towards Biggio and the adjacent stormwater garden. The runoff from this parking lot would be captured, filtered and released in a controlled manner back into Parkerson Mill Creek. Pedestrian pathways from this parking lot would be porous Type ‘D’ - Concrete Paving and would bring visitors towards the soccer facility via the aforementioned bridge, toward the intramural fields, or south along the Parkerson Mill Creek Greenway trail.

8

This area is reserved for a potential future pavilion that could be a base for outdoor gatherings, cookouts, intramural field event organization or other informal events. This setting would be park-like and a pavilion in this location would need to be constructed to be light on the land and visually penetrable.

9

An arcing path connecting the intramural fields to the soccer facility and adjacent parking would form an edge between the natural condition of the Parkerson Mill Creek Park and the parking facilities that serve it. This path would be lined with Quercus lyrata that would relate to the existing Quercus lyrata planting along Lem Morrison Drive. The line of trees that bisect this arc from the north, running past the gymnastics center to the proposed pavilion site, would be Quercus falcata.

10

Similar to item #5, this would be a light bridge structure that would be informal in nature. Likely a prefabricated steel bridge with timber decking, this structure would span the restored Parkerson Mill Creek section and provide access from Parkerson Mill Creek Park, south towards the continuation of the Parkerson Mill Creek Greenway trail.

11

This area should be cleared of existing invasive species, the ground plane opened and a lawn created for use as an informal park. This would be able to be used by students for informal gatherings and special events.

The restored Parkerson Mill Creek creek section would be bordered by a proposed Parkerson Mill Creek Greenway trail that would be informal in nature and constructed of crushed stone. This path will connect the urban core with the more agrarian landscape to the south.

Figure 6b-18. PMC Existing Conditions Section

1

Parkerson Mill Creek is incised as it flows next to the existing Biggio Drive. Its banks contain many invasive species and it is prone to erosion and scouring due to its culverted condition upstream.

2

Biggio Drive and the adjacent informal gravel parking area are very close to the edge of Parkerson Mill Creek and allow untreated stormwater runoff to flow directly into the creek.

3

The slope that leads up to the old track facility is well shaded but barren and eroding. This slope is highly visible from the adjacent Lem Morrison Drive.

Figure 6b-19. PMC Section Showing Potential Improvements

1

Restoring the Parkerson Mill Creek stream section will allow seasonal storms to be conveyed without causing erosion. Removing invasive species and replacing them with native, hydric species will reinforce the stream slopes.

2

Removing the informal gravel parking area on the western side of Parkerson Mill Creek and moving Biggio Drive to the west allows more room to regrade the slopes of the creek to lessen their steepness and reinforce the banks of the stream. This also affords the opportunity to locate a pedestrian greenway trail along the slope to provide an informal connection from the center of campus to the more agrarian landscape to the south. A more traditional shaded sidewalk should also be located at the edge of Biggio Drive to provide a street level pedestrian connection to the new recreation center.

3

Establishing a shade tolerant native understory at the slope adjacent to the old track facility will help the appearance of this intersection from Lem Morrison Drive and reduce the amount of erosion and subsequent sediment that washes into Parkerson Mill Creek.

Realign paths in the space to the east of Cater Lawn so the pedestrian circulation is oriented to the center of Cater Lawn. These paths should be Type ‘C’ - Concrete with Brick Bands. Tree planting should be formalized along Mell Street and Thach Avenue. These should consist of species like Quercus phellos and installed at 6” cal. or more so that they provide more immediate shade.

2

Cater Lawn should remain largely as is, though a simplification of the beds and trees along either side is suggested. These trees are currently in isolated mulched rings and the lawn between has informal edges.

It is proposed that the lawn should be made into a formal ‘panel’ and the area under the trees, on either side, be mulched and planted with an appropriate understory. This understory could consist of masses of Fothergilla gardenii and Hydrangea macrophylla framed by clipped Ilex glabra (maintained at 4’ tall). The trees should be maintained in good health and if replacement is needed, the replacement should be of equal size to the adjacent trees.

3

The park-like area to the west of Cater Lawn is currently divided by a multitude of smaller, meandering paths that lack hierarchy. It is proposed to simplify this path network with fewer, wider, paths that logically connect through to Cater Lawn and Thach Concourse. These paths would be Type ‘C’ - Concrete with Brick Bands. Existing trees planted in this area should remain and be allowed to grow to maturity in order to provide an informal shaded lawn for students to gather between classes.

4

The current intersection of the Thach, Tiger and Haley Concourses is not well defined and has too much exposed utility infrastructure around its edges. It is proposed to square off the corners of this major pedestrian intersection to provide area for shade trees in decorative tree grates with standard benches for people to sit and gather. This intersection should be paved with Type ‘B’ - Decorative Brick. The intersections along the Thach Concourse will distinguish themselves from the rest of Thach Concourse by their paving and tree species (Quercus coccinea).

5

The section of Thach Concourse to the north of Haley Center will be widened to accommodate a double row of shade trees with standard benches below them. The paving should be Type ‘C’ - Concrete with Brick Bands and will have 20’ clear to accommodate emergency vehicle access. The intersection between Thach Hall and Haley Center will be similar to the Concourse intersection but have a reduced paving pattern scale since the size of the intersection is smaller. The trees planted along the concourse, not in the intersections, should be Quercus shumardii.

Small bioswales along the northern edge of Thach Concourse will capture runoff from the upslope side of the Concourse, filter and release it back into the stormwater system at a controlled rate to reduce discharge velocities and subsequent erosion downstream. These bioswales should be planted with hydric species that can tolerate periods of drought such as Acer barbatum and Quercus bicolor. The understory and groundcover should also be able to tolerate brief periods of inundation and may contain species such as Cyrilla racemiflora, Iris, and Asclepias tuberosa.

7

Along the western part of Thach Concourse the current asphalt roadway, a remnant of when this part of the concourse was still accessible to vehicles, should be removed and replaced with impervious paving.

Shade trees (Quercus shumardii) should be planted in decorative tree grates and have standard benches located in between. Placing these trees on the southern side of the path will provide ample shade to pedestrians while still allowing 20’ clear access for emergency vehicles. Pedestrian scaled lighting should be located in relation to the shade trees but on the northern edge of the paved surface.

8

A pedestrian bridge should be located along the concourse to provide a grade-separated crossing over Donahue Drive. This bridge should be grounded on either end with cheek walls extending to the ground and would be clad in brick. The guardrail should be a standard steel rail with pickets at 4” o.c. and a steel top rail. This bridge should be designed so that grades are 5% max not requiring a handrail.

The current west Thach Pedestrian Concourse is an asphalt road with adjacent sidewalks. There is little shade or places to sit for users and the paving is impervious to up slope runoff.

2

There is little to slow or catch runoff from the adjacent hillside before it flows onto the concourse.

3

Adjacent grass areas in front of academic buildings have few trees that provide usable shade. These areas are often blocked from users by bollards with chains running between them.

1

By removing the existing asphalt and replacing with a pervious, low albedo pavement and installing shade trees along the southern side of the concourse with benches for seating, a more pedestrian scaled walking experience is made available to users.

2

Incorporating small raingardens adjacent to the concourse and between connecting sidewalks will help capture runoff from grass slopes and filter it before releasing in a controlled manner back into the stormwater system.

3

Removing the bollard and chain system from between the concourse and adjacent grass areas and providing larger and more closely spaced shade trees in these lawn areas will create an accessible, enjoyable space for faculty and students.
