Reimagining Southwest Philadelphia in Adaptive Way
Location: Philadelphia, PA, U.S.
Collaborative Work: with Isobel Morrison, Siddhi Khirad Spring 2022, Penn Studio 602
Instructor: Nicholas Pevzner, Christopher Marcinkoski
The project is about building elevated highgrounds for new districts in South Philadelphia. Through establishing urban armatures that includes educational outposts, civic buildings and public spaces, we connect community with water edge(wetlands), developing a more adaptive response to sea level rise and storm surge. This process can also trigger: providing more habitats for animals in larger context regarding to “coastal squeeze”, material reuse in demolition construction and maintenance which can bring job training programme and promote job rate in related opportunities, and also education on wetlands and ecology.

Tidal Wetlands
Integral Migration Sites
Atlantic Flyway Bird Migration
Future Scenario I: Sea Level Rise and Storm Surge
The project was designed in reaction to a series of compounding crisis that happened both locally in Philadelphia and nationall y in the U.S., the first one is the dramatic increase of sea level rise and storm surge. Development and urban renewal plan drained larg e part of the wetlands in southwest Philadelphia, leaving this areas with continually flooding problems. Looking into larger context, the Atlantic Flyway which is an integral stepover spot for thousands of birds each year is also affected. New habitats is needed wherever it could be found.
01
Managed Retreat and Connections: Using managed retreat as a way to connect fragmented green spaces, expanding the existing wetlands, and create connections between habitats.It also performs as a horizontal levee for facing sea level rise and storm surge.
Anchors, Public Access and Stewards: Using the existing insititution such as schools, libraries, and recreation center as anchor points. Turning the street intersections into pedestrianized streets and extend them into the wetlands to set ecological stewardship programs.
Heavy Industry: frequently flooded industrial parcels
Heavy Industry constant industrial zone since 1954
Green spaces parks and recreation
FEMA Flood: 100 year flooding areas
Future Scenario II: Increase of Climate Refugees and Managed Retreat
Mapping of much of what was being flooded was existing zoned industry along the banks of Schuylkill, causing enormous damage. The continual introduction of water into areas of heavy industry and brownfield sites was hugely disruptive to operations of industrial facilities, also spreading heavy toxins through the groundwater, surface water and soil. This gives the best opportunity to shi ft the private industrial land into city-owned green ecosystem patches and create new spaces for climate refugees in future Philadelphia and abroad.
Armatures and Fingers: Streets become public armatures that connects upland and wetland. Southwest Philadelphia shifts from facing central city to facing wetlands and Schuylkill river. Design 4 new neighbourhoods with raised ground and connected by pedestrian spine. As fingers goes into the wetland to aviod flooding.

RETREAT WETLAND: Wetland park and institutions. Retreated spaces turned into wetland as horizontal levee to reserve spaces for sea level rise. Parks and wetland institutions for education and research are established.
Wetland: The large boardwalk plaza, with the tank maidan in the background, as look-out spots and gathering spaces in the wetlands, design to provide access to the water and vegetations, observing birds and wetland habitants.
Library and Education Center Support a number of intergral programmatic functions for the neighbourhood - specifically, language courses, community college courses, as well as provide cooling and shelter spaces in hard climate situations.
Wetland: The boardwalk also supports an expansion of Philadelphia's Schuylkill river greenway bike path. Fishing piers are used constantly by fisherman and also ecological education programs, it perform as an educational outreach along with Bartrams Garden and John Heinz Wildlife Refuge in Philadelphia
Outpost: Cut-aways in the boardwalk provide visual engagement with the wetland and also a small research field for the outpost researchers. The outpost is the central office for the ecological stewardship program, including activities such as monitoring water, observing wildlife, etc.

Managed Retreat and Material Reuse
Imagine that with fossil fuel industries are slowly phasing out due to the uprising of solar energy and electricity. Previous industrial lands are turned over to municipalities for remediation, redevelopment, or reuse. This is the managed retreat acquisition strategy for parcels, which utilized three acquisition strategies: the rapid phase-out of historic fossil fuel industry, also voluntary buyouts and land swaps. This is a study of the order in which these industrial sites were purchased and rehabilitated by the government and how the construction materials on this land can be reuse into aggregate for raising the ground to protect sea level rise.
Phase 1 completed in process Phase 2 Phase 3 Phase 4 Phase 5 Phase 6
Project Vision demonstrate the potential of designing new urban spaces with existing civic infrastructures, illustrate the potential for a kind of public realm where care, community, ownership ,and education are part of the design of the space.
Futuring: In the upcoming years, the wetlands will continue to grow, moving upland into the gaps between the fingers of urban spaces as the rivers and seas moves upwards. The process of managed retreat for wetland creation repeated, making spaces for habitat while prioritizing urban communities.
The Hidden Stories of Coatesville
Revitalizing Through Telling Forgotten Stories
Location: Coatesville, PA, U.S.
Individual Work
Fall 2021, Penn Studio 601
Instructor: Todd Montgomery, Ellen Neises
Coatesville, an old town known for its previous steel production, is now facing a downturn in the city's economic and population in city center. My design area is about 18 ha(45 arce), proposing Coatesville as the starting point of a series of renovation projects in post-industrial cities throughout central Pennsylvania. By telling stories and materials that have been present in the old industrial city Coatesville as a way of continuing the unique memory, and also introducing new types of industries at lower rents, to stimulate Coatesville’s manufacturing glory.
1784
1990-2021
The town struggled with economic decline, none of the old factories remained. Leaving the area with high unemployement rate. Landfill corperations filled quarries and abandoned.
1970-1990
1980
"I don't have the money," said Kalb, who put in 28 years with Alan Wood, remained unemployed during the two years.
After the World War II, industrial plants relocated. Textile plants moved south, steel companies lost advantages competing with international cooperations.
1950-1970
Alan Wood Steel Company use 4 old quarries as landfills for solid waste and construction debris in the manufacturing process.
1980
Gerald Walker, 56, who lost his larynx to cancer after retiring at Alan Wood, cannot get either disability insurance or another job.
1980
"Where am I going to go," asks William Pagano, 23. "What am I supposed to do. Where else can I get a job that pays as well. I have no schooling."
1920-1950
Prosperity of the town and its industries, textile, quarry and steel industries. With the establishment of railroad, factories enable to ship their products to other part of the county.
1900-1912
Schuylkill Navigation Company construct canals and ports, with stagecoaches system, the town begin to prosperous in industry and retail.
1978
"You feel so helpless," worried Don Grosso, a 38-year-old purification engineer. "Go somewhere else. You know what that means? My father is 73. My mother is 68. All my friends are here. It's not easy to find somewhere else."
1970-1977
Struggle and failed to make balance, laying off young and old employees, eventually bankrupt
1835-1880
Towns in the region starts to grow giving large quantities of construction waste. Rolling mills, flavor mills and textile plants are proposed in the late 1800s in Norristown and quarry begin to reaching its peak.
1968
Employed 35,000 people, over half of Plymouth township's workforce.
1820-1835
Steady growth in industries. Different types of industries grow and verify: Iron, steel, metal fabricating, stone, clay, plastic, rubber. Preliminary Retail and Industries in textile industry as well as steel, stone and metal fabricating, multiple industries blooming.
1800-1820
Located on limestone belt, limestone quarry harvest grey marble for building constructions. Oldest industry of producing limestone ussing kilns to burn lime started in the 1700s, abandoned kilns can be seen alongside the roads.
Founded in Montgomery County with only 20 houses.
1950
Expand rapidly and as the economic mainstay of the area, recruit many local people
1826
First established in Conshohocken area
Landscape Palimpsests: Historic Story Layers and People Once Existed
As Coatesville expands through industrial development, these past layers are closely linked with the stories of generations of workers and local residence. It’s worth to commemorate the actions of these people in shaping the area and lands, showing how they brought the region to its former glory, producing steel for the construction of Pennsylvania and shaping and marking the land with their actions.

1950-1980
Story of Alan Wood Steel Company and its workers
Regional Background: Industries in Piedmont Region occur due to topography, transportation and river. The revitalization of Coatesville can be a trigger of several renovation projects and have the potential of eventually reshaping the whole area.

Design Proposal: Three Storylines of Coatesville
-Water: Restore the old Gibbsons Run that used to go through the centre of Coatesville and Ash Park(central park) to reduce the risk of flooding of low grounds.
-Development: Coatesville's development follows Lincoln Road and with the former railroad. Propose new development through reusing old historical buildings as craft technical school to train local unemployed people for re-employment. Also using abandoned plants as industry hub to support start-up companies.
-Commemorate line: Reuse of abandoned lands that used to be steel-making, wood stacks, coal storage industries. By bring these materials back to the ground we can commemorate the workers that make the town great and prosper. These lands also serve as public spaces for community gatherings, activities.
WALL MATERIAL INSTALLATION
PROJECTIONS
Site Material Study
A study of one of the historic industry on the site, quarrying. The major production of Coatesville is Piedmont Schist, one of the stones that popular in Piedmont region and on site. By exploring traditional stone cutting technique, I produced the stones with particular textures formed when it breaks up apart.
Then thinking about how to apply the stones in different landscape elements such as wall and roadside curbs to commemorate old quarry industry. The stones are arranged differently to show the texture of the cuts, the heaviness and self-stablilty of the stones. It als remind people of the history of Coatesville.

Recreating a Disappearing Forest
Closer forest experience through a slowly disappearing forest
Location: Washington D.C., U.S.
Individual Work
Fall 2022, Penn Studio 701
Instructor: Karen M'Closkey
The maple-beech-birch and spruce-fir forests are slowly disappearing from North America with climate change. Their habitat has repeatedly moved northward and will slowly fade out of our site - Washington, D.C. Design intends to create a series of gardens related to climate change in the U.S. arboretum to commemorate the forests of these departing species, and to bring people closer to experience the beauty of these forests, to feel the plant changes over time in miniature.

Forest Condition In Large Washington D.C.
The entire northwest and southeast of the large Washington D.C. area is mixed forest, with a large number of white oak, red oak, hickory, maple and loblolly pine trees. A large number of oak trees and maple trees in D.C. is having diseases and not doing well due to the temperature growth and precipitation decrease. National Arboretum is a perfect place to demonstrate these types of trees changes through time due to climate change.

Ecoregion Shifts and Tree Migration
In the last 30 years, with the southeast seeing drier conditions and the central U.S. getting wetter, climate and ecoregions in the U.S. are changing drastically. Ecoregions shifts have huge impacts on tree migration. Trees are moving towards more suitable living environments by avoiding hotter conditions. Trees are moving west and north, and move up the Appalachian Mountains.

The site was once a historical piece of ancient woods before the establishment of national arboretum. The composition of this forest is the same as the forest tree species in the greater d.c area, oak and hickory. There's also conifer collection and asian collection that contains a lot of spruce and maple trees, giving a great opportunity in demostrating and designing gardens of climate change.

How Industrial Island Response to Sea Level Rise
Location: Yokohama, Japan
Individual Work
Fall 2020
Climate change has brought more intense natural activities and increase human transformation activities sharply, which drives us to take urgent countermeasures and stop the malignant expansion, so how to create interesting, sustainable and resilient landscape systems to accommodate human activities become the major issue.
Yokohama, Japan, an industrial port which contains a series of islands known for cars manufacture, shipping, storaging and chemical production, also facing intense industrial transitions due to land losses. Lands that bound to be submerged in 2100 are facing the result of gradually retreated to post-industrial wetlands, but how to protect lands that still has manufacture or storaging requirements? How to protect lands that has economic incomes and retreat certain lands that can be submerged?
Site Location with Industrial Transition Collage and Site Information Data
Yokohama port is an essential shipping dock and manufacture areas in Tokyo Bay area. However, due to population and working age people decline, second industry are shrinking rapidly and giving space to third industry. Thus, industry retreat to wetlands are a inevitable trend.

Biyunfeng Village Productive Landscape Design
Location: Yiyang City, Hunan Province, China
Individual Work
Fall 2020
Prosperity of landscape architecture constitutes the adaptation to natural crisis, striving to is to pursue the concept of “the harmony between man and nature” without any restriction to the developmnt.
Biyunfeng Village is a small village located in Hunan Province, south of China and base mainly on agriculture and animal husbandry. Large abundant of water brings crayfish, a invasion species into the river system and also by-products of graiery brings water pollution. In addition, young adults seek for working opportunities in big cities leaves the village not enough labour forces. With not enough workers and increasing pollution, how to use water as a system and use natural forces instead of human labour, such as water levels and climates and temperatures to form a more profitable productive mode is a main problem.
Problem Collage
Though high industiral income has arisen in recent years, its agriculturee remains in a low level. Graziery and second Industry cause too much pollutions and crayfish incasions, with the problem of aging and loss of labour, the village is facing a turn in economic structures for survival.

Natural Water
Natural water is a water system formed on the mountain. It collects rainwater and dew from nature to form a natural water system, drift from high altitude to low altitude residential areas.
Landscape Water
Combine both natural water in the mountains and water from the local reservoir, transform into landscape water which provides landscape effect and also create a better living environment for the local residents.
Wetland Water
Wetland water is located between farmland and residential areas. It can improve the local microclimate and environmental quality while solving the biological invasion of animal crayfish
Farmland Water
Farmland Water is set to provide sufficient water for the farmland, at the same time, it can provide the water needed for fish farming, and it can also play a buffer role in the drought and flood period, giving enough water supplies.
Village Agricultural Timeline
Design sychronize climate, water level, crops with fish and crayfish, building a contineous and long-lasting productive timeline that can eliminate crayfish, harvest crops and having fishery at the same time. Saving fodders and reduce labour

Design of a Sunken Plaza in Beijing Forestry University
Location: Beijing Forestry University, Beijing, China
Individual Work
Fall 2020
The plaza was located in Beijing Forestry University, which is also where I study right now. It's located underneath as the entrance to the ground level auditorium and teacher's working studio. I found out that most people just merely pass the site without really staying inside and trying to create a stream of walking paths and topology to contain people's leisure time activities inside and enlarge the use of the plaza, not only for an opening entrance but also for a relaxation place for people going by and wanting to stay to work or study outside and be close to nature.

Project's Purpose
The project intends to simultaneously: (1) increase job opportunities through reforestation projects (2) use specifically designed species of trees in reforestation to clean up Pittsburgh's air pollution (3) creating wilderness in the city, using the soil conditions of the reforested area to promote natural plant growth and reduce artificial maintenance costs, increase ecological benefits. The study will analyze vacant parcels’ potentials and suitability in planting trees.
Results and Process of the Simulation
By analyzing the Pittsburgh area from a larger scale, the location of suitable sites for tree planting was gradually narrowed down to a smaller scale with a suitable vacant parcel. By using basic analysis of land geography, slope, and water catchment, the sites were selected and gradually ranked as suitable for planting, and the first sites were developed. A series of analysis results were obtained by using GIS

Drawings, Traditional Pavilion Design (Left), and Plant Study (Right)
I also explored in hand drawings, especially pen drawings and sketches. During the 3rd semester at Penn, I attended a plant study and drawing class that I focused on flowering tobacco (a type of ornamental plants that used in landscape) and studied its growth habit, leaf formation, and plant structure. After carefully drawing it, I imagined the the future of this plant as it evolves with hawkmoth, one of its associated species.
Grasshopper Simulation
During Spring 2020, I leraned grasshopper and especially, Physarealm proram, which can simulate people's moving directions and the gathering of people in different spots. The program using ant colonies to represent human beings and through setting "food" which is attractions and "barriers" which is obstacles on the way to imitate people's walking and touring line.
Results of the Simulation
choose a village near a water dam and resevoir in Miyun, Beijing. Using the topology and the resevoir's reserved area as the obstacles and the working locations, farmlands, power stations, etc. as the food source. Showing the most common way of people in getting these places from the village. This can be used as a design references in planning and finding the best road system.
