INTRODUCTION
Drexel University I Landscape Design Guidelines • 5
Introduction
Background
Drexel University has major plans to expand the physical facilities, research
capabilities and student enrollment of its campus in West Philadelphia over the
next five years and beyond. As outlined in Drexel University's West Philadelphia
Campus Master Plan prepared by Burt Hill in 2007 (Master Plan), these changes
are building upon the University's ongoing renaissance since 1995. The Master
Plan proposes the construction of new campus buildings and open spaces
between 2007 and 2012. Additional projects are proposed for development
beyond 2012.
The Master Plan recognizes the importance of promoting the urban character
of the Drexel campus by siting buildings close to the street and walkways to
define the public streets and interior walkways. The Master Plan recommends
strengthening pedestrian connections and links among the residential, athletic,
academic and commercial areas of the campus. The Master Plan also
emphasizes the importance of developing a unique identity to unify the campus
and distinguish it from the surrounding neighborhood.
Purpose
In support of the recommendations in the Master Plan, Drexel University's
Planning Design and Construction (PDC) engaged Lager Raabe Skafte
Landscape Architects to develop the campus-wide Landscape Design Guidelines
represented in this document. These Guidelines will provide the structure
necessary to establish consistency, quality and identity of Drexel's public realm
as part of the design and construction of future projects.
The effort to create a distinct identity and character for Drexel's campus focused
on the selection of standards for elements typically found in the public realm; the
spaces and places between buildings encountered by students, staff and visitors
as they move about the campus. A campus composed of a series of thoughtfully
designed outdoor spaces will present an attractive and inviting environment
for the Drexel community as well as for visitors and prospective students. The
following Design Principles informed the development of the Guidelines:
• Distinguish Drexel from the surrounding neighborhood businesses
and other universities by creating a consistent statement about the
campus environment.
• Create an attractive campus environment.
• Focus on comfort and quality.
• Consider ease of maintenance, material replacement and overall costs.
• Incorporate environmentally sustainable materials and strategies
where possible.
• Select native plants, where possible
• Privilege pedestrians over vehicles.

• Lager Raabe Skafte Landscape Architects
To facilitate the on-going implementation of these Guidelines as new projects are
constructed, existing outdoor spaces have been categorized into seven distinct
campus use zones according to their different functions and daily use.
• Building Entry
• Usable Green Space
• Landscape Setting
• Social Gathering Space
• Identity Intersection
• Campus Walkway
• Pedestrian Streetscape
The planners and architects of future additions to the campus will be able to
incorporate these Guidelines for site improvements into their designs by;
1) identifying the use zone(s) that the new construction will create, and
2) adopting the recommendations for each zone detailed herein.
The site improvement requirements for materials, furnishing configurations, plant
selection and location are tailored to each Campus Use Zone. The information
provided is intended to direct the selection of materials, manufacturers and
construction techniques.
Implementation
Refer to the Campus Use Zones depicted on Diagrams 1 and 2 (pp. 8 and 12)
to understand how a new project will fit into Drexel's campus. Further definition
of each Use Zone with a list of required and optional elements is located on pp.
9-11, 13. Each element includes a page number where the specific guideline
can be found as well as supplemental drawings illustrating desired material and
spacing details or design intent.
All new campus projects are required to adhere to the Landscape Design
Guidelines outlined in this book as part of PDC's review and approval process.
These Guidelines are not specifications. Design professionals are responsible
for developing and submitting details based on these Guidelines for each new
project as individual site conditions may vary.
Reevaluation
These Guidelines are not meant to be a static document. Therefore, periodic
internal reviews by PDC and future consultants will be necessary to determine
whether desired goals are being met, manufacturer's information and materials
are current, and to address conditions that are unknown at the time of this
writing.

Campus Use Zones
The Campus Use Zones defined below support distinct campus activities and
require the provision of specific types and arrangements of site improvements.
Refer to the stated guidelines for each use zone for every new project.
BUILDING ENTRY: Outside areas adjacent to building entrances. The
Landscape Design Guidelines see Building Entry as more than a space to pass
through. A Building Entry is an opportunity to promote informal interactions
among students, faculty and staff and offers a place to meet and wait for others.
The materials, planting and site furnishings in these areas support these activities
and complement the building entrances by defining a place.
Required Elements:
• Paving materials (pp. 26 - 27)
• Use zone planting (Figure 15, p. 32)
• Benches (pp. 44 - 45)
• Lighting: post lights and building mounted or illuminated bollards (pp. 47 - 49)
• Trash and recycling receptacles (p. 51)
• Ash urns (p. 52)
• Bicycle racks (p. 57 - 58)
• Building identification signs - must be clearly legible (refer to Drexel's Planning, Design
and Construction (PDC) standard)
USABLE GREEN SPACE: Lawn areas providing space for informal student
recreation, such as hanging out with friends, picnicking, frisbee throwing,
sunbathing, people watching or reading. Usable Green Spaces are the heart of
the campus and are strategically located throughout the residential, commercial,
athletic, academic and commercial areas. The organization of these spaces is
clearly visible and contributes to the campus atmosphere. Similar to Harvard
Yard or the Lawn at the University of Virginia, the Usable Green Space is
a signature space for the campus and contributes to the identity of Drexel
University. The materials and site furnishings invite lounging and landscape
grades are easy to access. Planting and site furnishings are located at the edge
of the space. Visibility of the space from the sidewalk is critical as is visibility of
the sidewalk from within the space to facilitate sociability as well as safety.
Required Elements:
• Use zone planting (Figure 20, p. 36)
• Seating options in shade and sun
– benches and bench configuration (pp. 44 - 45)
OR
– built in seating such as seat height walls
• Trash and recycling receptacles (p. 51)
• Lighting (pp. 47 - 48)
Drexel University I Landscape Design Guidelines • 9
Campus Use Zones
LANDSCAPE SETTING: Areas adjacent to buildings and throughout the
campus that feed into or support the campus buildings and environment.
These areas are not occupied spaces. They are planted and are meant to
provide an aesthetic accent. Lawn with trees are standard. Where additional
planting is desired and can be maintained, plants should be chosen with special
consideration given to varied seasonal interest, mix of textures, hardiness and
native species.
Required Elements:
• Use zone planting (Figure 16, p. 33)
SOCIAL GATHERING SPACE: Paved areas located primarily near student
dormitories, athletic facilities and the student center. These areas provide space
for formal group events such as those sponsored by student organizations as
well as informal socializing. These are comfortable public spaces that invite
student use and are, preferably, near to places where students can purchase
food. These spaces are near to campus areas with high pedestrian traffic and
provide a place for posting information about university wide activities. If located
at Identity Intersections or other strategic places, confer with PDC for signage
requirements.
Required Elements:
• Paving materials (pp. 26 - 27)
• Use zone planting (Figure 17, p. 34)
• Seating options in shade and sun
– benches and bench configuration (pp. 44 - 45)
OR
– tables and chairs (p. 46)
• Lighting: post lights and/or illuminated bollards (pp. 47 - 49)
• Trash and recycling receptacles (p. 51)
• Ash urns (p. 52)
• Bicycle racks (p. 57)
Optional Elements:
• Grills (p. 59)
10 • Lager Raabe Skafte Landscape Architects
Campus Use Zones
IDENTITY INTERSECTION: Intersections located at key gateways into or
within the Drexel campus and define the campus visually and spatially. Many
of these intersections are at the center of high vehicular and pedestrian traffic.
Special preference is given to pedestrians with specially marked pedestrian
crosswalks. Primary intersections are marked with a distinctive Drexel logo at
the center of the vehicular intersection. Materials and site furnishings are highly
visible, provide directional and University activity information and create a sense
of identity for the campus. As depicted on Diagram 1, the intersections are
categorized as primary or secondary based on their proximity to the campus
core.
Required Elements:
Primary Intersections
• Vehicular intersection (p. 28)
• Signage (confer with PDC for requirements)
Secondary Intersections
• Pedestrian crosswalks across all streets (p. 29)
• Signage (confer with PDC for requirements)

Campus Use Zones
CAMPUS WALKWAY: Pedestrian walkways internal to and used by students,
faculty and staff to traverse the campus. These walkways provide a sense
of continuity and identity throughout the diverse urban fabric of the campus.
Primary Walkways are the most heavily used, connecting the academic buildings,
residences, gym, dining and social facilities. Secondary Walkways are fewer
in number and traverse shorter distances. Tertiary Walkways, too numerous to
identify, are all other internal campus paths which serve as connectors to Primary
or Secondary Walkways and receive the least amount of regular foot traffic.
Paving patterns, materials and site furnishings differ slightly according to the
walkway category.
Required Elements:
• Primary, secondary or tertiary walkway paving pattern (pp. 18 - 19)
• Lighting: post lights and/or illuminated bollards (pp. 47 - 49)
• Non illuminated bollards (p. 50)
• Trash and recycling receptacles (p. 51)
• Bench options in shade and sun (pp. 44 - 45)
PEDESTRIAN STREETSCAPE: Public streets that run within and border the
campus. Although these streets and sidewalks are not internal to the campus,
they are heavily used by Drexel students and contribute greatly to the campus
environment. These streetscapes are also used by motorists and pedestrians
passing through the campus and play a role in creating an impression on the
general public. The use of consistent materials and site furnishings along these
streetscapes will create a more distinct image and identity for Drexel's campus
and distinguish it from the surrounding area. Preference is given to crossing
pedestrians at street intersections (see Identity Intersections, p. 11).
Required Elements:
• Paving pattern (p. 20)
• Use zone planting (Figure 18 and 19, p. 35)
• Lighting (p.47 - 48) for smaller streets
• Philadelphia City standard brown round light for larger streets
• Trash and recycling receptacles (p. 51)

SECTION 1: PAVING
Paving is the primary element used to connect campus walkways, social
gathering spaces and building entries within the campus as well as to distinguish
these areas from the non-university realm. The paving materials and patterns
selected for use define these prominent campus areas with a special character
and quality. Providing a consistent paving pattern and material on the walkways
will make the campus more attractive to the pedestrian. Establishing guidelines
for walkway widths that respond to the hierarchy of campus walkways will make
circulation clear for faculty, students, staff and visitors to the campus. Using
consistent materials (pp. 26-27) for the Campus Walkway, Building Entry and
Social Gathering Space will help establish a distinct campus identity and simplify
area maintenance.
Drexel University I Landscape Design Guidelines • 17
1: Paving Patterns

1: Paving Patterns
Pedestrian Streetscapes
Pedestrian Streetscapes with street tree planting provide a distinct visual rhythm
along streets for pedestrians and motorists.
Street trees are under a great deal of stress when planted in an urban
environment. The use of a continuous planting trench allows for greater soil
volume which will increase the potential root health of the tree. This will reduce
the stress on the tree, allowing for a higher rate of growth and longer life. Space
trees every 15’ minimum to 20’ maximum in groups of two to three. Consider
sidewalk width, underground and above ground utilities and sight lines when
determining where to locate trees. Refer to p. 37 for Street Tree list.
Tree Trench Width: 6' wide - Primary, 4' wide - Secondary and Tertiary
Pattern:
Poured-in-place concrete with 4' min. - 6' max.
control joints and expansion joints at 24' min. - 30' max.
Material:

The figures below show required depths for concrete and aggregate base for
both pedestrian and vehicular use. The Design Principles advocate incorporating
environmentally sustainable strategies where possible. To facilitate this goal,
the use of porous concrete that allows water infiltration to the soil below is
recommended. This option is not only sensitive to the environment, it can also
help the project meet Philadelphia Water Department stormwater management
requirements.

SECTION 2: PLANTING
Trees, shrubs and groundcover add to the outdoor aesthetic and temperate
environment of the Drexel campus. The selection of a consistent palette and
setting for plant materials adds to a distinct campus identity. In addition to the
ornamental color and texture trees, shrubs and flowering perennials bring to the
outdoors, trees provide shade and lower the overall area temperature by several
degrees.
Consideration for planting design throughout the campus should include
placement and details for the installation of canopy, ornamental trees and shrubs
in the ground or in planters as well as the overall choice of plant species. The
Design Principles advocate incorporating environmentally sustainable strategies
and using native plants where possible. To facilitate these goals, native plants
are marked with an asterisk " * " on the lists that follow. These plant lists are not
exhaustive and may be added to as required by specific project conditions.
Some Campus Use Zones require special considerations for planting. Refer to
figures on pp. 32-36 for planting diagrams for Building Entry, Landscape Setting,
Usable Green Spaces and Pedestrian Campus Use Zones.
