Urban design is a tool we use to shape cities and their inner dynamics, allowing them to transcend existing problems and adapt to constantly evolving social, economic, and ecological contexts. Its ultimate goal is to improve the quality of life within communities and fostering environments that are inclusive, resilient, and sustainable. As cities face growing challenges such as climate change and inequality, it is clear that traditional methods of place-making are no longer enough. Urban challenges today cannot be solved through conventional spatial solutions alone; they require strategies that bridge social, economic, and environmental systems while responding to the lived experiences of local communities. This means drawing from disciplines such as ecology, data science, public health, and social policy to inform how we plan, design, and manage urban spaces. By integrating knowledge from diverse fields and embracing innovation, urban design can move beyond static forms to create responsive frameworks that evolve with the city. They will adapt to changing conditions, and strengthen the capacity of communities to thrive. In this way, urban design becomes a catalyst for transformation, enabling cities to function as dynamic ecosystems where social, environmental, and spatial systems coexist in balance, supporting longterm resilience and sustainability.

01 RESEWING URBAN SEAMS An Urban Studio on Post-Oil Imageries Group Project with Jadwiga Gawlik Parker Fall 2024 Instructor: Jeffrey Nesbit

The pressure of urbanization and rising human consumption demands have driven largescale landscape manipulations and the profound alterations of natural water systems with new infrastructural technologies. To meet the needs of the ever expanding urban population, cities implement extensive infrastructural interventions like damming rivers, constructing artificial lakes, channelizing waterways, and building vast irrigation networks to support the increasingly intensified scope of food production. Human activities have significantly destabilized this natural cycle in many ways, leading to issues such as water scarcity, increased flooding, and degraded water quality.

In the face of the multifaceted challenges and threats caused by the failures of the contemporary water managing systems and institutions, we find ourselves under the desparate need for new urban models that incorporate more adaptive systems of water management infrastructure and a more coherent juxtaposition of the public realm with the ecological landscape in which it was situated.

In this studio, we used an incremental approach to explore contemporary practice of urban design, particularly investigating the challenges in and around the post-oil industrial area of the Bellwether District. For roughly 150 years, it operated as one of the nation’s largest oil refineries and one of the city’s top air polluters. Organizing the project around several themes across different scales and dimensions of urban forms, we investigated the interrelationship between the built environment, community development, and ecological restoration, and developed an integrative approach that address the issues of environmental and social sustainability through bridging the landscapes of natural hydrology and the man-made landscape of a post-industrial metropolis.

The Vital Interplay Between Urban Development and Hydrological Landscapes

Regional Hydrology and Sewerage

Urbanization and rising consumption demands have led to large-scale landscape changes and significant alterations of natural water systems through infrastructure like dams, artificial lakes, channelized waterways, and irrigation networks. These interventions have destabilized natural cycles, resulting in water scarcity, increased flooding, and degraded water quality.

Proposed Solutions

In the face of the multifaceted challenges and threats caused by the failures of contemporary water management systems and institutions, we find ourselves under increasing pressure to rethink our water infrastructure and reimagine how it functions within the broader ecological context. This requires not only redesigning systems to be more resilient and adaptive but also reintegrating our urban environments into the natural hydrological landscape.

The site is located at the confluence of the Schuylkill River and the Delaware River, placing it within a critical juncture of Philadelphia’s hydrological network. From a regional perspective, the city lies within the porous Schuylkill River watershed, an area historically interconnected by numerous streams that have since been buried due to modern urban development. Two of these historical streams present opportunities for potential reintegration into the urban hydrology, though such efforts must be carefully evaluated against the robustness of existing infrastructure. The site itself lies within a considerable floodplain, making it particularly susceptible to flooding due to its proximity to the watershed and generally low elevation.

Site Analysis - Regional Scale The areas of Germantown/Chestnut Hill and Manayunk/ Roxborough feature higher tree canopy coverage, a stark contrast to the site, which has been heavily impacted by its historical industrial use and low elevation. This deficit necessitates significant attention to canopy restoration to address the surrounding shortage and enhance environmental quality. The site also suffers from limited transit connectivity, lacking sufficient ties to the surrounding area and the broader region. Its accessibility is currently dominated by highways, highlighting the need for improved multimodal transit options to integrate it more effectively with its urban context. Additionally, the site has a history of dense refinery activity along the waterfront, driven by the ease of transporting goods via nearby waterways. This legacy presents critical challenges related to the carbon footprint and environmental contamination. Effective remediation strategies are essential to address these impacts and lay the groundwork for sustainable redevelopment.

This site-scale analytical map further visualizes the low elevation of large swaths of the site relative to adjacent hydrological networks.

The site is currently zoned as I-3: Heavy Industrial District, meaning intensive, high-impact uses, including extractive industries and petroleum processing and storage.

Waste Operation and Detected Contaminants

Public Transit Mobility

There is a high concentration of toxic contaminants on-site and in surrounding areas due to decades of industrial use.

The site lacks necessary public transit, bike-ability, and walk-ability, and is largely disconnected from its immediate surroundings.

Hybrid Urban Blocks

Land Use Design Strategy We transformed the floodplain footprint into an ecological setback on the site, prioritizing resilience and environmental restoration. To complement this design vision, we developed integrative block types that balance density with the ecological setback, creating a harmonious middle ground. These blocks are designed to incorporate wetland and park features, softening the edge between built environments and natural systems while fostering a seamless integration of urban and ecological elements.

Exploring new block typologies based on the existing dimensions of the Philadelphia Urban grid, we developed hybrid urban block types integrating features of water management as key components with their existing functions within the urban realm.

Regional Water Management

To refine these blocks, we conducted a detailed water flow analysis, adopting a systems-based approach to design. Our project’s overarching goal is to achieve a truly comprehensive system of water management—one that benefits both the restoration of the natural ecosystem and the community inhabiting the site. This approach is guided by the principles of Delay, Retain, Restore, Reuse, and Release, ensuring a holistic and sustainable water cycle.

Building on this foundation, we introduced a grid and assigned land uses to establish a mixed-use, higher-density urban core adjacent to existing development. This approach aims to attract residents and create a vibrant community while simultaneously protecting and restoring the natural ecosystem. By thoughtfully balancing urban habitation with ecological preservation, the design fosters a symbiotic relationship that enhances both human and environmental well-being.

Development Timeline and Phasing Strategy

Stakeholders The development is envisioned in strategic phases, each aligned with partner involvement to ensure sustainability and impact. It begins with extensive land remediation, addressing environmental challenges and preparing the site for future use. The next phase introduces residential and mixeduse spaces, creating housing alongside businesses and community spaces to establish a vibrant and inclusive environment. Finally, the site evolves to include office, commercial, and educational facilities, completing its transformation into a dynamic, multi-functional area. This phased approach balances ecological restoration with urban growth, fostering a collaborative and adaptive process that integrates community needs while protecting and revitalizing the natural ecosystem.

02 THE GREEN CIRCUIT A community design for South Philly's Stadium District Group Project Spring 2025 Instructor: Scott Page Group Members: Xindi Lyu, Yanru Fang

The transformation of the site offers a rare opportunity to craft a resilient, inclusive, and healthcentered residential community in South Philadelphia's Stadium District. Our proposal builds on the site's strategic location between major transit corridors and FDR Park to re-frame a car-centric landscape into a walkable, family-oriented neighborhood defined by connectivity, wellness, and commu­nity belonging. At the core of this vision is a human-scaled street network that prioritizes pedestrian movement, layered green corridors, and curated crossings. These include raised and textured pedestrian paths that not only enhance safety at key intersections, but also physically and symbolically link homes to plazas, parks, and transit nodes. In doing so, the site becomes a place with integrated, safe, and inviting mobility.

This re-imagined site design aims to rebalance nature, civic infrastructure and public life through an ap­proach that's not only inclusive but also resilient. Overall, the design creates shared space for all and further strengthens the quality of life for the South Philly community.

We identified a list of housing types that exist in the surrounding neighborhoods to integrate in our own proposed housing mix for the site. The project mirrors the existing urban fabric while introducing new opportunities for density and diversity.The variety of housing forms also allows for a broader range of household types and income levels, meeting the demands of both long-term residents and newcomers. Rowhouses and duplexes provide a familiar, human-scaled edge along neighborhood streets, while mid-rise buildings define key nodes along the pedestrian loop and near open spaces.

03 SEQUENCING PUBLICITY A Systematic Intervention for the Street of Hoan Kiem Individual Project Spring 2021 Instructor: Trevor Ryan Patt

“Intensive processes possess nonmetric properties in subtle and complex ways: sometimes they involve the spatial continuity and indivisibility of properties like temperature, pressure or density; other times the anexact yet rigorous way in which cellular spatial neighbourhoods are defined; sometimes what is involved is nothing specifically spatial, but rather that which remains topologically inv-ariant in a spatial process; and other times specifically spatial capacities are concerned, such as the capability of adaptive components to fold, stretch or bend.” ------ Manuel DeLanda

Historically, the development of urban space and architectural design has always been a bilateral procedure with reciprocal effects on the contemporary public and private sector of urban space. The boundaries between the inside and outside, public and private are ultimately formalized based on the negotiation of different individuals. Public space is not in itself oppositional to privacy. That a space is accessible, or even visible to the public does not preclude private activity, introspection, or rituals. These moments occur all around the city, though spaces explicitly dedicated to them are becoming increasingly rare.

This project takes place in the congested old town of Hanoi, Vietnam, where the subtle gradation between the public and private is reintroduced into the condensed urban fabric. The design is an embodiment of juxtaposed public and private experiences, interfacing with the existing environment, and informing new modes of interaction within the irregular conditions of the city streets.

Hoan Kiem is one of the four old quarters of Hanoi, Vietnam. It is also the commercial core of the city, with preserved shop-houses packed along all the main streets, and vendors roaming around the busy sidewalks with traditional goods and handicrafts carried on their scooters. It is a compact urban district with a long history of development, where the well preserved colonial architecture, traditional temples, and commercial streets attract hundreds and thousands from all across the world. For the residents, however, the quality of life is degraded due to the old and excessive infrastructure.

The Dong Xuan neighborhood north of the old quarter is used as the focus area of the project. It is one of the most populated areas and the largest trading center of Hanoi.

The interiors of the lightwells provide a variety of enclosures integrated within the larger communal space of the open market. The twisting concrete structure of the lightwells allows it to cast dramatic shadows within the enclosures.

The main entrance to the alleyway is now highlighted with a lightwell that performs as a doorway to the market area.

The lightwell also extends on both sides of the entrance, forming two passageways cutting into the two adjacent storefronts on the mainstreet.

The second floor is attached with more floor panels to give space for handicraft workshops. This creates additional businesses for local handicraft vendors.

On the third floor, additional floor panels are connected from the rooftops of the adjacent residential buildings to the lightwells, forming a levitated outdoor space exclusive to the Hoan Kiem residents.

The top of the lightwells become additional wall members on the top level of the addition, forming a rooftop garden for the community, which is accessible from the roof of their own homes.

The first floor functions as an open market with stalls and counters available for rent, providing a legitimate and regulated space for street vendors to set up their businesses. The lightwells morph into different forms from top to bottom and help stratify different layers of public spaces.

04 UNLOCKING HADDON AVENUE A Downtown Action Plan for Haddon Township Group Project Spring 2025 Instructor: Summer Xiaoxia Dong, Chris DiStasi Group Members: Xindi Lyu, Rujie Cheng, Jasmine Wallack, Tyler Meynard, Hansen Xie, Kavana Raju, Maggie Bai

Haddon Township Downtown Action Plan identifies goals and recommendations to reinvigorate and strengthen downtown Haddon Township’s main commercial corridor, Haddon Avenue. Over the last 150 years, Haddon Avenue has transitioned from a thriving streetcar suburb to an auto-dependent corridor. This shift has led to an overabundance of parking and vehicle-centric infrastructure that prioritizes cars over pedestrians. At the same time, many parts of downtown retain the charm and form of walkable downtown district featuring welcoming storefronts, outdoor dining, and a central public square. With a significant portion of the community living on or near Haddon Avenue, enhancing the pedestrian experience is a top priority.

This plan envisions Downtown Haddon Township striking the perfect balance between serving as a lively commercial district and a neighborhood for locals. Every recommendation is tied to a real location to ensure the corridor evolves in a connected and context-sensitive way. Each goal reinforces the others: strong public spaces and better mobility will help businesses thrive, while new development and parking strategies will make the Avenue more welcoming and accessible for everyone. These strategies are not isolated, they are part of a coordinated effort to shape the future of Haddon Avenue as a place for people, not just cars.

Context

Haddon Township Today Haddon Avenue is a key commercial corridor Single-family housing dominates the landscape, accounting for 56 percent of total land area. Recreational and green spaces make up 16 percent, offering significant open space for residents. Multifamily housing occupies just one percent of the land, yet nearly one-third of them are located near Haddon Avenue.

As the primary commercial corridor, Haddon Avenue plays a vital role in concentrating both economic activity and higher-density residential options.

Haddon Township is located in Camden County, New Jersey, about six miles southeast of Philadelphia. The study area for the Downtown Action Plan covers approximately 64 acres in the heart of Haddon Township. It includes all parcels along Haddon Avenue, as well as key developments and public assets within a five-minute walking radius of the main street.

The study area is bounded by Cuthbert Avenue to the west and the municipal boundary with Haddonfield to the east (just after Ardmore Avenue).

This boundary captures the core of the township’s commercial, residential, entertainment, and transportation activity. This plan aims to enhance existing strategies for the corridor by providing a more detailed examination of how previous documents have addressed Haddon Avenue.

The evolution of Haddon Township and its main street, Haddon Avenue, dates back to before it became officially incorporated as a municipality in 1865. The avenue has long served as a connector between other municipalities and the cities of Philadelphia and Camden.

Haddon Avenue has limited access to parks

Heat island effect is the strongest on Haddon Avenue

Although the town has several public parks, including Cooper River Park, Crystal Lake Park, Newton Lake Park, and Saddler’s Woods, they are all located beyond the 10-minute walkshed of Haddon Avenue.

Urban heat island is prevalant on Haddon Avenue, which could be one of the main cause of the lack of pedestrian engagement compared to adjacent municipalities.

Conditions of the Avenue Haddon Avenue is an important neighborhood asset but faces several challenges Haddon Avenue stands out amongst a sea of mid-Atlantic suburbs full of shopping malls and cookie cutter houses because of its charming local businesses, relatively compact organization, and walkable main street. However, its current design limits its ability to be a fully accessible and welcoming downtown for all users. As Haddon Township evolved from a streetcar suburb to a more typical auto-oriented suburb, the physical realm evolved in response to the competing demands of cars, pedestrians, and businesses throughout downtown, ultimately prioritizing motor vehicles and reinforcing patterns of urban sprawl. Consequently, Haddon Avenue faces several challenges related to the competing demands of cars, people, and businesses throughout its downtown.

Improvement Opportunities

Improvement Strategies

Underutilized public spaces

Increase public amenities Simple, low-cost interventions like popup lawns and small play installations can activate the space year-round.

Enhance public access

Haddon Avenue features several public spaces with strong potential for community events, but they remain underutilized, particularly on ordinary days.

Utilizing inclusive street and spatial designs to ensure equitable access to these shared spaces.

Diverse array of businesses

Establish business incubators Vacant buildings can berepurposed at a low rent cost to test new ideas and grow existing businesses.

Improve storefront designs

While certain segments of Haddon Avenue feature vibrant and engaging storefronts, the presence of large parking lots along the corridor often creates deep setbacks that weaken the connection between businesses and the sidewalk.

Clear design guidelines can help businesses present their brand effectively while contributing to a unified corridor identity.

Insufficient street infrastructure

Add trees and street furniture Increasing tree canopies along Haddon Avenue can enhance the pedestrian experience and help mitigate the urban heat island effect.

Add pedestrian infrastructure Repainting existing crosswalks and installing pedestrian beacons would address the existing gaps between crosswalks.

The corridor is well served by Westmont PATCO Station and NJ Transit bus routes. However, the corridor lacks the infrastructure to support safe and comfortable walking.

Activating Neighborhood Public Spaces

Haddon Square has the potential to become a vibrant destination for everyday life and casual social interactions, not just a site for special events. Given its central location and ample open space, it can support a broader range of daily programming that invites people to linger, connect, and relax.

For the Municipal Plaza, the design focuses on providing a natural, calming environment for everyday use, encouraging people to pause, reflect, and connect with nature. An outdoor reading corner could also be included, offering a quiet space for reflection and a connection to the broader community.

The addition of interpretive elements, such as commemorative plaques, historical markers, or memorial pavers, can further enhance the space’s connection to the local community, ensuring the stories of those it honors remain part of the public consciousness.

The East Side Parklet presents a unique opportunity to reclaim underutilized street space and provide public resting area on the eastern end of Haddon Avenue. To achieve this, they incorporate movable seating, layered planters, and compact shade structures that can be easily reconfigured based on changing needs.

Implementation

Future vision and phasing strategy The overall vision for downtown Haddon Township is to strike the perfect balance between serving as a lively commercial district and a neighborhood for locals. This vision translates to four goals: enhance streetscapes and public spaces to reflect local identity and create a more engaging experience; support local businesses through promotions, programming, and storefront design guidelines; encourage higher density mixed-use residential redevelopments to create diverse, and affordable housing options; and to create safe, sustainable, and healthy transportation options for all residents and visitors.

A phased approach can help balance immediate improvements with long-term investments. Short-term actions focus on low-cost, high-impact changes that build momentum. Long-term actions involve more substantial capital investments and policy coordination that align with the township’s broader vision. Implementing these recommendations will require coordinated planning, funding, and construction.

05 IMPASTO JFK Terminal 4 Concourse Expansion Group Project Project Partner: Yuxin Huang Fall 2021 Instructor: Hal Hayes

This project explores the functional and iconographical role of the new concourse extension, both as a templated agency to fulfill the core spatial requirements of aviation as well as passengers' needs for leisure activities. The new extension is the stage where visitors manifest their first impression of the city. The design investigates the limitations of the contemporary airport typology and proposes an alternative configuration of its rigid program arrangement. By incorporating and overlapping the spatial parameter of service and amenity, interior and exterior, natural and industrial, a new formal vocabulary is introduced, anticipating a concourse reinvented to not only offer all the amenities of the physical city but also resembles the dynamic, multilayered “urban condition” of New York.

The concourse is infused with a variety of special programs, including the gallery, theatre, playground and a series of indoor and outdoor gardens. These programs provide vignettes of the dynamic urban experiences of NYC. The design process starts with the critical examination of the existing concourse of terminal 4 and proposes new formal logic that reiterates the traditional concourse construction. The new spatial prototypes are developed based on a series of overlapping conditions that informs the three-dimensional juxtapositions of functional programs in the concourse. The distinction between columns, walls, and floor panels are obscured and redesigned with a continuous catenoid surface that loosely defines the spatial boundaries inside. The concourse therefore becomes not only a live canvas painted with various fun activities, but also is a live artifact itself. Its canvas-like roof takes on the vibrant color patterns of growing vegetation, which responds to seasons and climates. Echoing the Central Park and Highline, the roof adopts an artistic pattern for rainwater harvesting. Based on sunlight exposure, different types of vegetation are arranged according to their specific growing conditions, creating a vibrant, kaleidoscopic pattern that transforms the landscape into a living work of art.

Site Analysis

Passenger Activity Map in Terminal 4

The Terminal Systems studio focuses on the expansion of New York’s John F. Kennedy International Aiport’s Terminal 4 Concourse B.

The existing sectional configuration of JFK's concourse facilitates a rigid program arrangement. Passenger experiences are limited within the spatial and visual confinements of each layer of the building.

The JFK Airport is known as the first large scale international airport in world history. By the time this grand design of "Terminal City" was finished, it was considered a symbol of the country's power, freedom, and individualism. Since then, the advanced aviation industry brought

by JFK has also become symbolic of New York City, as the evolution of the airport also embodies the historical changes of the city.

The design aims to reimagine this programmatic diagram to increase the visibility and accessibility of each departure program with each other. It also aims to blend the boundary between exterior and interior spaces. The reconfiguration starts with exploring different overlapping conditions as spatial prototypes, where structural columns, floor panels, and walls are treated as a continual catenoid surface for construction.

Kit-of-Parts Generation Co-Produced with Yuxin Huang

A kit-of-parts was developed to explore alternative forms for the basic structural components. With the catenoid surface acting as the underlying geometry, new column, skylight, and window shapes were derived to create a unified spatial language. The kit-of-parts was employed to generate a range of functional zones within the concourse, allowing the structural logic to shape spaces for movement, interaction, and visual experience.

OTHER WORKS 01 PANDEMIC MODELING WITH GIS

Based on the clustering pattern of the percentage positive rate of covid-19 in New York City, we can clearly identify that the south and lower east side of the city show a significantly higher rate of covidpositive test results among residents. Lower Manhattan, on the other hand, has a significantly lower covid-positive rate in general.

From this analysis, we can see that the clusters with highest death rates from covid-19 are outside the east side of Manhattan. At the same time, it is still the Manhattan Island that had the least death rates from the illness

In this scenario, I determined the number and location of facilities that the Bronx County would need so that each resident in this area would be able to access at least one pandemic response center within a 30-minute walk. The result generated here includes 10 facilities in total in between 2-4 zip codes.

In the second scenario, I located 3 facilities in the Bronx so that overall travel distance for all residents to the response centers would be minimized. The result is as follows: the three chosen facility locations are closer to the center of the county, and also within zip code areas with larger populations
