RECONNECTING COMMUNITIES PILOT PROGRAM

Our studio prompt takes inspiration from the Reconnecting Communities Pilot Program, which is a federal program that strives to reconnect communities previously cut off from economic opportunities due to transportation infrastructure.

Philadelphia is one of 45 cities that have been awarded planning and capital construction grants through this program. Through this studio, we had the opportunity to meet with people who provided insight into the process and philosophy behind it.

TIMELINE

Benjamin Franklin Pkwy officially opened in 1918 as one of the region’s first major thoroughfares. The construction of Vine St Expressway in the 1960s played a key role in the growth of Philadelphia. However, the presence of the Vine St Expressway tunnel made walking between Center City and the Museum Area difficult.

1682

1951

In the early 2000s, the tunnel began experiencing recurring flooding incidents during heavy rain, with the most severe occurring in 2011 and 2021. Despite these challenges, the Vine St Expressway remains an essential transportation artery, and efforts are ongoing to address the flooding issues and ensure its continued safe operation.

1960

William Penn and Thomas Holme envision Vine Street as a 50-foot right-of-way and the citys northern boundary The Fairmount Parkway, known today as the Benjamin Franklin Parkway, officially opens to traffic. The first section of the Vine Street Expressway opens from the Schuylkill Expressway to 17th Street. The Vine Street roadway is expanded to ten lanes, in anticipation of the expressway linking the Schuylkill Expressway to I-95. The remnants of Hurricane Ida in 2021 caused historic flooding in the Philadelphia region. 2021

TRAFFIC

• Today, Benjamin Franklin Pkwy and Vine St are two of the busiest streets in the region, with a high volume of daily traffic. According to the Pennsylvania Department of Transportation’s Traffic Volume Maps, Benjamin Franklin Pkwy has an average daily trip count of 16,000, while Vine St sees around 133,000 daily trips.

• In addition to these major thoroughfares, the nearby I-76 highway also sees a significant volume of daily traffic, with an average daily trip count of 135,000. These roads play a crucial role in connecting Philadelphia with other parts of the region, as well as supporting local commerce and transportation needs.

NEIGHBORHOOD REDEVELOPMENT

• Under the corridor project, it is crucial to improve the pedestrian-friendliness of the Museum Area and Center City. To achieve this, filling in the I-676 tunnel and redeveloping the street-level community is essential. This effort not only helps to improve the area’s flood resilience but also changes the street environment and experience in Museum South.

EFFICIENT NETWORK

• Under the corridor project, the new transportation infrastructure prioritizes pedestrian-friendliness and ecological resilience over traffic capacity compared to the previous tunnel. Therefore, strategies are being implemented to improve traffic efficiency, such as converting two-way streets to one-way streets

• In addition, a new roundabout is being designed on the east side of the area to converge traffic, improving the flow of vehicles while also creating a safer environment for pedestrians and bicyclists.

PUBLIC TRANSIT CENTER

• Under the corridor project, the underground trolley system will be brought to the surface at 21st Street via a street-level transit building. Additionally, the trolley rapid traffic line and bus transit network from 22nd to 20th Streets will be improved to reduce traffic congestion, enhance urban accessibility, lower tailpipe emissions and air pollution, protect the city environment and residents’ health, and promote social equity.

CONNECTING

• To improve ecological resilience and enhance the community environment, Museum South will be connected by a green corridor along Winter St, 21st St, and Benjamin Franklin Pkwy. Additionally, there will be an open plaza in front of Calder Garden for community residents and visitors to enjoy.

• These green spaces will help to reduce stormwater runoff. The open plaza will also serve as a gathering space for community events, enhancing the vibrancy and social cohesion of the area.

COMMERCIAL

• The community will feature a Retail & Entertainment complex spanning 172,000 square feet. The environment of the community will be engaging, walkable, inclusive, and vibrant, creating a welcoming and lively atmosphere for residents and visitors alike.

• This development will not only create new economic opportunities for the area but also enhance the overall vibrancy and sense of community in Museum South.

PARKING

• The newly developed parking facilities will include 600 spaces, including public parking and street parking. These parking options will help to improve accessibility and convenience for residents and visitors, while also reducing the reliance on private vehicles and promoting sustainable transportation options.

RESIDENTIAL

The newly developed apartment complex will feature 480 units, including 50 affordable housing units. This development will not only create new housing opportunities for residents but also promote affordability and social equity in Museum South.

The corridor project aims to create a more sustainable, walkable, and inclusive community that benefits all residents. By prioritizing green infrastructure, sustainable transportation, and community engagement, the project seeks to promote economic opportunities, reduce housing insecurity, and create a more vibrant and resilient community. With a mix of market-rate and affordable housing options, as well as new retail and entertainment opportunities, the project aims to create a more diverse and accessible community that reflects the needs and aspirations of all residents.

Site Area Arts Education ST

There are several opportunity sites within the neighborhood, which can be split into publiclyowned and privately-owned.

Publicly-owned parcels include areas where the expressway is currently located and a parking garage owned by PennDOT.

Privately-owned parcels are underutilized sites that could be redeveloped as a result of development on the publiclyowned sites.

STATE STREET, CHICAGO

Based on this analysis, we started to develop an idea of what the Broad and Vine area has the potential to become. Along with the need for housing, community development, and multimodal connections, this is the first point along the corridor as we move east where the potential of Vine Street as a high-volume commercial corridor can be realized.

Looking at precedents like State Street in Chicago, we thought about how to bring arts, transportation, and community into one cohesive plan, leading us to our guiding vision.

CONCEPT & GOALS

Broad + Vine is an intergenerational community that bridges across income and age to foster connections from people to people and from people to place.

130

GOALS

Affordability Accessibility Health Sustainability Arts & Culture

Use the abundance of public land to create development that caters to a wider range of household types and incomes.

Use transit and walkable street typologies to promote connectivity within and beyond the Broad and Vine neighborhood.

Minimize environmental health disparities, such as the historic impact of the Vine Street Expressway on pollution, traffic safety, and flooding.

Develop resilient environmental, economic, and social systems that support the neighborhood today and carry it through the long-term.

Rebrand the area and connect it to other cultural hubs of Philly, such as Logan Square, Chinatown, and Avenue of the Arts, to create a vibrant destination.

The green space network is an important part of making Broad and Vine accessible, healthy, and sustainable. The small courtyards and plazas connect to the assets of Logan Square and the Rail Park on either side of the neighborhood.

LOGAN SQUARE RAIL PARK WOOD STREET PARK Pennsylvania Convention Center

WOOD STREET PARK

The new Wood Street park is the keystone of the green network in the Broad and Vine Area. It is located where these onand off-ramps exist today, but with the removal of the Vine Street Expressway, they will no longer be needed.

149

WOOD STREET PARK

The northern half of the ramps site can be redesigned into a neighborhood park, as there are buildings on all four sides of the block.

To support intergenerational living, the park features flexible outdoor spaces that can be used as classrooms for school field trips or arts performances, recreation space, or venues for community gatherings. The park also utilizes the depressed landform to serve as a detention basin for stormwater runoff.

TANNER SPRINGS PARK, PORTLAND

Tanner Springs Park in Portland can serve as a precedent for this design, as it handles significant grade change in creative ways and allows space for recreation and stormwater management.

STORM WATER MANAGEMENT

Each of the new parks, plazas, and courtyards would be designed to maximize permeability through landscape beds and permeable pavers. Each of these spaces acts like a sponge, diverting some of the runoff that flows towards Vine Street.

LOCATION

Centrally located along the Vine Street Corridor, the Rail Park neighborhood stretches from Noble Street in the north to Arch Street in the south and from Broad Street on the west side to 11th Street on the east side.

KEY ANCHORS

Source: Hoang An Tran, Visit Philadelphia

Source: Tutor Perini Affiliates

The neighborhood surrounding the Rail Park has a range of community anchors that bring a lively cultural presence to visitors and existing residents alike. With key institutions like Asian Arts Initiative and the Pennsylvania Convention Center, the area’s existing assets create a prime opportunity to enhance its cultural presence.

159

WHY REDESIGN THE RAIL PARK?

Historically, Chinatown has faced adversities as a result of the imposition of unchecked development in an around the neighborhood, driving displacement. Today, the neighborhood still faces these challenges, as it remains physically divided, and the proposed 76ers arena threatens the existing population. Given the historical presence of this area along the corridor, this project presents a great opportunity to reimagine the way that development like the Rail Park can serve the existing population while bringing in new visitors.

160

KEY ISSUES TO ADDRESS

Neighborhood Continuity

Accessibility

Parking Lots

Taking the neighborhood’s location, cultural assets, and history into account, this proposal focuses on neighborhood continuity, asset accessibility, and programming the undeveloped spaces that are currently used as parking lots.

GOALS & STRATEGIES

Increase accessibility

Create community conscious development

Bridge Center City north of Vine

This project’s design strategies are centered around shifting the Rail Park into a more useable, accessible space. In order to better serve the Chinatown community, this project creates community conscious development that extends the Center City district further north.

Blend Arts & Culture Corridor with Chinatown

North - South Connections

Mixed Use Hubs and Programmed

Outdoor Space

By pulling visitors into programmed spaces further north, the Vine Street can evolve into a continuous connector that makes the neighborhood feel pedestrian-friendly.

Reshaping the Rail Park aims to unify the neighborhood’s identities by bridging uses north and south of Vine and building more accessible, pedestrian-oriented neighborhood amenities that serve both visitors and the existing community.

162

SITE PLAN & PRECEDENTS

The site plan removes the undeveloped portion of the Rail Park viaduct and opens up the southern part for programmable park space, effectively scaling down the Rail Park. The plan blends a range of scales for each element, creating hubs for commercial and mixed use spaces and designed outdoor spaces. Traffic is intentionally slowed at key locations and shifted to “shared streets” to create a pedestrianfriendly neighborhoods that connects to the underground trolley line.

At grade, the Rail Park is a solid structure with pedestrian and shared streets that penetrate on the east-west streets. Above grade, the elevated Rail Park features interactive planters with seating and an open park design that can be programmed into an event space

166

NORTH HOUSING COMPLEX SECTION

The housing complex at the northern edge of the site features distinct zones of programming. Privatized by the surrounding residential and mixed use development, the interior plaza creates a micro-development for local residents and a view of the Rail Park on the northern side.

Overall, the neighborhood interventions include about 4 acres of park space, 5,000 residential units (2,000 affordable units), 160,000 sq. ft. of commercial office space, and 330,000 sq. ft. of commercial space.

167

SITE PLAN SOUTH

South of Vine focuses on shared streets and activating space on the northern edge of Center City. The design redevelops the pre-existing parking lots in a style that responds to Center City development. Implementing mixed use in these spaces, a shared street jogs just south of Vine Street to connect the new development to the green spaces. Vine Street on the block between 11th and 12th Streets features different pavers and a street tattoo to intentionally slow traffic and pull visitors into the Rail Park.

EXISTING CONDITION

This site locates between 9th Street and 6th Street, bordering Philadelphia’s Chinatown on the west and Philadelphia’s eastern gateway - Benjamin Franklin Bridge. With so many resources surrounding it, This site should be a transition that connects Chinatown to the Old City and Delaware Riverfront. However, the connection is now broken because this area is where the highway lifted to connect to I95 and Benjamin Franklin Bridge. In other words, this neighborhood should be the busiest section of the entire Vine Street Expressway. After we remove the expressway, what does a new Chinatown eastern haven need if there’s no expressway?

HISTORY

• From the Delaware River up toward Walnut and 3rd Streets, the city’s wholesale food hub was well into the mid-20th century when the food distribution center was built in South Philadelphia.

• As a neighborhood close to the bridge, it was once an important commercial district.

• The figure shows a clear grid layout for the neighborhoods near the docks, which consist of large warehouses.

ZONING

• The expressway cut the site, and there have some low-quality commercials with a large area of vacant space and parking lots on the north side of the Expy Besides, there are also two warehouses and the building density is very low. About the south side of the Expy, where is the old city community, almost all of the buildings here is for residential and the construction density is higher than the north side of the Expy.

PLAN

CREATE EFFICIENT PUBLIC TRANSPORTATION

ROAD PLAN

• The Callowhill St from a one-way street to a two-way street, and add a traffic circle on the south side to help organize traffic better.

• The main exit and entrance of the Benjamin Franklin Bridge at 6 St were combined. The combined entrance and exit direct traffic coming off the bridge to the traffic circle on the north side, which slows down traffic to the grid.

CREATE EFFICIENT PUBLIC TRANSPORTATION

• Infill a large number of underground garages.

• Add on-street parking between Old Town and the boulevard.

CREATE A MIXED-USE COMMUNITY INFILL STRATEGIES

Commercial development along the street, with office towers placed above the podium. Add apartments behind the complex.

CREATE A MIXED-USE COMMUNITY SECTION

The community will be a dynamic center of activity, providing modern workspaces that cater to diverse businesses. The integration of apartment buildings within the office block will offer convenient housing options for the workforce, creating a live-workplay environment that promotes community interaction and inclusivity.

CREATE A MIXED-USE COMMUNIT Y CONNECTIVITY OF GREEN SPACES

The park within the redevelopment plan will be a green loop, offering a much-needed respite from the urban environment.

CREATE A MIXED-USE COMMUNITY GREEN BELT

The pedestrian system in the green loop connects the old city to the corridor and links the whole district to the Delaware Riverfront.

The facilities here include the community service center, small gallery, mini-market, and small construction providing rest space.

LOCATION

The site includes I-95, Callowhill Street, Race Street, Christopher Columbus Boulevard, and the Delaware Waterfront.

258

INSTITUTIONAL CONTEXT

The area of focus includes important cultural resources and connections to nearby neighborhoods with historical and artistic initiatives including Old City, South Philly, Northern Liberties, and Camden.

259

ENVIRONMENTAL CONTEXT:

STORM SURGE

• Increasing potential for riverine flooding and storm surge

• Water quality is a critical consideration

• Sea level in the Delaware Bay will rise an additional two to five feet

NOAA Cat. 4 Storm Surge

ENVIRONMENTAL CONTEXT: COMBINED SEWER OVERFLOW

• The area is served by the combined sewer area, which means runoff during rain events leads to the release of unfiltered sewage into the river

• Climate change will lead to more extreme storm events

PWD CSO Area

ENVIRONMENTAL CONTEXT: HEAT AND AIR QUALITY

• Heat is an increasing health risk in urban areas

• The site’s proximity to the I-95 highway increases exposures to air pollution and heat for visitors and inhabitants

• Temperature-sensitive vehicle pollutants like ozone will become an even greater health concern with climate change

OpenDataPhilly Heat Scores

ENVIRONMENTAL CONTEXT: INEFFICIENT USE OF LAND

• The I-95 highway and Vine Street ramps take up a significant amount of space on the site, limiting the available land for other uses and contributing to the fragmentation of the urban fabric.
