5 THE VISION When completed, will help to transform University City into one of if not the most sustainable, mixed-use urban centers in the country. Throughout much of the 20th century large-scale urban redevelopment and urban institutional projects in the United States have made a significant impact to our cities and communities, but that impact has not always been beneficial to the local communities that they serve. Such projects, while well-intended and often very successful as business or academic ventures, have often created significant displacement and disruption in those communities, and have at times exacerbated issues that can divide us such as race, class, and income disparity. Not surprisingly, new proposed developments are now often viewed with suspicion and mistrust. Today, presents an opportunity to create a model for this type of development that embraces the history and culture of the local community. The strategic objective of The Platinum Corridor TM is to create an innovation corridor that not only will be a new model of a collaborative center of innovation, discovery and entrepreneurship but will also be a model of community engagement, job creation and economic opportunity. Through the leadership of University Place Associates and its Founder, Scott Mazo, who has a 25 year plus history of working in West Philadelphia and its many unique communities and neighborhoods, there will continue to be an enduring spirit of humanity and respect at the forefront of the ethos. Beginning with 2.0 University Place located at 41st Street and Powelton Avenue, University Place Associates has demonstrated a firm commitment to sustainability goals as well as a sensitivity to new construction within its neighborhood context. For the future phases of The Platinum Corridor TM the intent is to continuously expand upon these principles and develop an innovation corridor on Market Street that augments the University City Science Center development to the east and establishes this district as one of the preeminent centers of research and innovation in the United States and the world. also presents the opportunity to build upon the momentum of emergent types of work environments that are occurring worldwide. Co-working and distributed workforce environments are becoming ever more prevalent and desirable for businesses and institutions offering unequaled flexibility and access to collaborative initiatives for both start-ups and established enterprises. intends to provide these options to businesses and enterprises already located in the Philadelphia and Delaware Valley region and as well as for those looking to locate from elsewhere. The purpose of this urban design study is to create a framework to guide the future development of to achieve these strategic objectives during the course of its implementation. Recognizing that implementation will likely occur over a number of years and potentially engage multiple development entities it is the goal of this study to create an overall vision and identity for the architectural expression of the buildings and the public realm while allowing for adaptability to respond to evolving market conditions and programmatic needs. 5

16 INNOVATION DISTRICTS KENDALL SQUARE / CAMBRIDGE, MA Many cities across North America are planning or are building innovation districts with the goal of attracting and growing innovative new businesses and creating collaborative environments for businesses, start-ups, institutions and universities. There have been notable successes such as Kendall Square in Cambridge or South Lake Union in Seattle that have leveraged the proximity of thriving urban centers with leading research universities. shares similar assets as these successes with its proximity to Philadelphia Center City, U Penn, Drexel and the Science Center, and it also is embedded into a community with a rich history and culture. This provides with the unique opportunity to create an innovation district that not only will become an economic engine for the city and the region but also one that creates jobs and economic opportunity for local communities and entrepreneurs.

19 SITE ANALYSIS THE HISTORIC GRID + NEIGHBORHOODS + FOCAL POINTS The design of is based on understanding the unique attributes of this specific section of Market Street in West Philadelphia. The area features a unique street and block geometry resulting from the historic street patterns that evolved from Philadelphia s westward expansion, creating conditions that can be leveraged to create a district identity that is distinct from any other district in the city. 19

21 1800 S STREET GEOMETRY Historically, Market Street extended the east-west axis of the William Penn center city plan, with diagonals leading northwest to Lancaster and southwest to Baltimore. These diagonals resulted in street geometry that varies from the typical gridded pattern of most of the Philadelphia plan. The historical evolution of the street pattern in West Philadelphia creates a unique urban condition in the surroundings of The Platinum Corridor. TM. 21

25 NEIGHBORHOOD FABRIC A key element of this section of West Philadelphia is the degree to which the original neighborhood fabric remains intact in the neighborhoods to the north and south of Market Street. One of the goals of development is to retain this character and to reflect the scale of this urban fabric in the ground level treatment of all new development in the district. 25

29 There are four primary street typologies in the district, each lending a distinct character to their adjoining neighborhoods and development: URBAN ARTERIALS: Market Street and 38th Street. 100 foot R/W width. 60 foot roadway and 20 foot wide sidewalks. These streets have relatively high traffic volume and due to the roadway width lack some of the walkable character that some of the smaller street types have. NEIGHBORHOOD STREETS: Typically the north-south streets from 39th Street to 42nd Street. 54 foot R/W width, 30 foot roadways. These have relatively low traffic volume and feature much of the fine grain historic fabric, linking that environment to Market Street. SECONDARY STREETS: Chestnut Street and Powelton Avenue. 76 foot R/W width, 45 foot roadways. These streets have moderate traffic volume and their frontages have retained more of the historic urban fabric than exist on the arterials. SMALL NEIGHBORHOOD STREETS: Sansom, Ludlow, N 41st Streets. 40 foot R/W, foot roadways. These narrow streets carry low traffic volume and have an eminently walkable and intimate scale, recalling the historic fabric of old Center City Philadelphia. 29

37 DESIGN FRAMEWORK will be a highly sustainable, transit-oriented, pedestrian-based, inclusive and vibrant urban community of innovation. It will engage and intersect with the surrounding residential communities and its world class University and Healthcare neighbors. In cities around the world urban spaces play a key role in defining the memorable experiences that create lasting value for surrounding neighborhood, businesses and institutions. The Platinum Corridor district will be defined by a public realm framework that will establish an identity on Market Street from 39th Street to 42nd Street. At each end of the district a new public space will be created: The Gateway Green to the east and The Platinum Commons on the west. These spaces will not only create public amenities but will also become addresses for the new developments facing them. 37

39 The character of will to a large degree be created by the design of the public realm extending along Market Street from 39th Street to 42nd Street. Each end of the district will be anchored by a new gathering space designed to fit within their specific urban contexts. Enhancing the public realm is accomplished primarily using three strategies: 1 / CREATING GATEWAYS + PUBLIC SPACES: The Platinum Commons and The Gateway Green anchor either side of the district. These open spaces exhibit sculptural seating elements and branded sculptural beacons that announce The Platinum Corridor s TM extents along Market Street and celebrate the art and culture of the district. These landmark spaces provide relief from the typical concrete streetscape along Market Street, while also providing important public space and connectivity to surrounding neighborhoods. 3 / INTEGRATING BRAND + DISTRICT IDENTITY: Through the implementation of new site furnishings, artistic installation, lighting fixtures, and signage, a distinct character and identity for The Platinum Corridor TM will be established. The sculptural seating elements and sculptural beacons portray the corridor s character as a cutting-edge innovation district with public, collaborative, and social spaces dispersed throughout. A consistent material palette and contemporary furnishing family stitches The Platinum Corridor s TM various urban and architectural character together, and allows future architecture and development to vary and evolve as needed. 2 / THICKENING THE PEDESTRIAN EDGES: The addition of bump-out spaces, both mid-block and at all intersections, creates stormwater infiltration zones throughout the district and creates a comfortable pedestrian environment buffered from the heavy vehicular traffic typical along Market Street. These zones are planted with resilient native plant species that add scale, color and interest to the streetscape throughout the year. Additionally, at key focal points along the corridor, sculptural seating elements celebrate important connections to the surrounding neighborhoods. 39

40 THE PLATINUM COMMONS This space will be created in the early phases of implementation of the Corridor, establishing the district identity from the beginning of the new development. It will be located on the northwest and northeast corners of N 41st and Market Streets and will create a distinct threshold into the district on the western approach along Market Street. The geometry is based on the alignment of N 41st relative to Market Street and acknowledges the significance of 41st Street as an important corridor linking University Place 2.0 with the rest of developments ST STREET 4.0 GATEWAY BEACON Powelton Avenue Filbert Street SCULPTURAL SEATING STORMWATER BUMP-OUT MARKET STREET N 41st Street N 41st Street SCULPTURAL SEATING Ludlow Street Market Street 5.0 ROOF DECK GREEN ROOFS, TYP

42 THE GATEWAY GREEN The Gateway Green would occur in latter phases of implementation of the corridor and is intended to create a green amenity bisecting the long block south of Market Street between 39th and 40th Streets. The space would serve as a demarcation between 7.0 and 8.0 and provide an open space amenity to both of those developments as well as for the senior housing community to the north. It addition this will create a mid-block pedestrian connection between Market Street and neighborhoods to the south. MARKET STREET GATEWAY BEACON PAVILION PAVILION GREEN ROOFS, TYP.

44 FOCAL POINTS The shifts in the street grid create opportunities for terminated views and special architectural features that would not be available in other parts of the city that have the more typical grid street pattern. These occur at the shifts in 41st Street along Market Street, the bend in 42nd Street at Market Street, the eastern terminus of Filbert Street at 41st Street, and the southern terminus of North Preston Street at Market Powelton Avenue Filbert Street N Preston Street S 40th Street N 42nd Street N 41st Street N 41st Street Market Street Ludlow Street Chestnut Street 44

45 Specific focal points are used to bring in surrounding neighborhoods and engage the community. These could be expressed architecturally and/or programmatically. 45

46 ROOMS The room is the beginning of architecture. -Louis Kahn The concept of the Room will define the character of the lower floors of all new buildings in The Platinum Corridor TM. There are two purposes behind this concept: 1) THE NEIGHBORHOOD: New development in will be sympathetic to the scale of historic development patterns found in West Philadelphia, both the townhouse residential development of the neighborhoods to the north and south of Market Street but also the historic small scale neighborhood commercial development still found in sections of Market Street. The Rooms are divided into approximately 30-foot wide bays that articulate the new buildings along the street frontages into pedestrian-scaled modules. 2) THE PROGRAM: The Rooms will be the space where the program of will engage with the street and be made visible and accessible to the public. Research and innovation work should not be only isolated in the upper floors of the new buildings but should also engage visibly with the community and symbolize the accessibility and economic opportunities it represents to the community. Likewise the Rooms may be spaces for small business enterprises and activities to allow for entrepreneurial initiatives to blossom.

48 STREET FRONTAGES The assemblage of properties in enjoy generous street frontages on Market Street and the side streets leading north and south into the surrounding communities. Of particular significance is the double frontage on the north and south sides of Market Street between parcels 3.0 and 4.0 as well as 5.0 and 6.0: Here there is an opportunity to create a complete urban environment with a consistent architectural expression and articulation of the public realm that spans both sides of Market Street.

50 POTENTIAL START-UP SPACE: THE ELWYN BUILDING In order to thrive, innovation districts require a diversity of work environments at different price points to accommodate the needs of a diverse tenant mix, from start-ups to established enterprises. It will be important in to create relatively economical space for startup businesses and incubators. As an existing building with large floor plates the Elwyn Building provides an excellent opportunity to create such space. It can readily be re-configured to create flexible, open office and research environment at a lower cost than new construction. Primary architectural improvements: Atrium: New, central skylit atrium or courtyard to provide daylighting into the building interior. Façade: New façade treatment on Market Street. Open the ground floor with storefronts and transparent street entrances. Re-clad the upper floors to create a new identity consistent with new buildings in The Platinum Corridor. Market Street N 41st Street 50

51 Renovate Elwyn Building and use for affordable rent space for local start up businesses. 51

52 FLOOR PLATES Office building floor plates may be limited in depth to 90 to 100 feet maximum to optimize daylight penetration and views to the outdoors. Numerous studies have concluded that access to natural light and views creates measurable improvements in employee health and productivity as well as reducing energy costs by reducing the need for artificial lighting, which also further reduced cooling loads.

54 MASSING All new buildings may share a basic massing concept to create a common language within the district, while allowing for individual architectural expression of the different phases. The plinth may be a common feature throughout the Corridor, incorporating the concept of the Room at ground level to create the walkable scale, neighborhood connectivity and programmatic diversity intended to achieve the strategic goals. 54

58 PROGRAM: RETAIL + OFFICE The goal of is to create an environment that attracts and fosters innovation, collaboration, entrepreneurship at multiple levels, and community engagement. Businesses today increasingly place high value on locating in amenity-rich settings that may attract the best talent available. Distributed workforce models are placing jobs closer to where the workforce lives, rather than forcing employees into commuting lifestyles. is wellpositioned to capture a share of this market in the Philadelphia and Delaware Valley region. In addition to space for established businesses and start-ups, The Platinum Corridor TM hopes to create new spaces for community uses and businesses located in the ground floor plinth. This space program is conceptual only and is based on current assumptions about programmatic demands and densities allowed by the current zoning. The building envelopes are based on the continuous two story plinth articulated in a series of rooms that house both retail uses and programmatic uses representing the businesses occupying the upper floors.

64 PUBLIC REALM: STORMWATER INTEGRATION builds on the previous framework developed by the City of Philadelphia and communicated in the City of Philadelphia Green Streets Design Manual (2014). Synthesizing the typically separate systems of stormwater management, street engineering, and landscape architecture develops a comprehensive street system that benefits the environment and society.

65 The conceptual stormwater framework takes into account the existing slope of the district, with the approximate high point at 39th Street and low point at 42nd Street. Surface water is captured in a series of stormwater bump-outs, green gutters, and tree trenches located throughout the district. These components together create a comprehensive stormwater management system that is integrated into the experience of the public realm.

66 PUBLIC REALM: STREET SECTION ENHANCEMENTS Utilizing and building on the best practices established in the City of Philadelphia Green Streets Design Manual, The Platinum Corridor s TM street enhancements provide functional stormwater management, improve pedestrian comfort, and aesthetically soften the urban landscape. Stormwater bump-outs are implemented at all street intersections, narrowing the roadway to slow traffic and providing a green buffer between vehicles and pedestrians. SECTION MARKET STREET: 96 ROW Street trees are provided with the maximum possible uncompacted soil space through the use of continuous stormwater tree trenches, belowgrade silva cells, or other similar urban soil systems. Green gutters are implemented on one-way small neighborhood streets where single-sided parking is acceptable and mid-block stormwater bump-outs are not possible. Designated bike lanes are continuous along Market Street and on all other streets where the right-of-way width allows. Artistically designed pedestrian crosswalks further distinguish the district as a unique Philadelphia destination.

68 PUBLIC REALM: MATERIALS Contemporary, durable, regionally sourced materials will be used throughout the public realm. In tandem with the City of Philadelphia s streetscape standards, The Platinum Corridor s TM material palette is designed to define hierarchy throughout the public realm. Precast concrete pavers demarcate the planting and furniture zones adjacent to the street, and bring scale and texture to major public plazas and primary spaces. Crushed stone, durable wood products, and metals are used as secondary materials in smaller spaces and site furnishings throughout the public realm. Pervious paving systems may be used in less-trafficked, secondary pedestrian zones. Planting areas provide buffers between vehicular and pedestrian movement while minimizing hardscape and contributing to stormwater management and heat island reduction. The plant palette should provide year-round interest and function, and be comprised of primarily native, resilient species. 68

69 PUBLIC REALM: FURNISHINGS Site furnishings add color, scale, continuity, and interest to the public realm. Furnishings should be arranged and lighting integrated to promote a sense of safety, high visibility, and inclusiveness in order to engage a range of users. Site furnishings provide identity and branding opportunities, as they can serve as sculptural elements and wayfinding. Integrating locally fabricated elements will strengthen community ownership and further establish a site-specific identity unique to the district. 69
