Desert in the Ice 01

Site Utqiagvik, Alaska

Area 49,060 ft² (4,557.83 m²)

Instructor Mathew Jull + Leena Cho

Keywords cryosphere, snow management, drainage system, climate change

Utqiagvik is the northernmost city in the US territory, orginally developed from indigenous communities but currently populated by deployed scientists or army. Within an extreme climate as a cryosphere, infrastructure may be threatened by a ton of snowpiles. In summer, when the temperature becomes above zero Celsius degree, accumulated snow becomes potential hazards within the city in terms of flooding and vulnerability of underground soils. To keep the permafrost stable enough to sustain the infrastructure, time-based management is required. The goal of this project is to develop maintenance regimes in terms of specific characteristics of Utqiagvik and Public Works.

Cryosphere and Snow Management Timeline

The unique dynamics of this landscape have made Utqiagvik a scientific hub for climate research for almost 100 years. Most of the scientific research and experimentation takes place outside of the city even though outcomes of these studies have implications for the city itself. The same changes in the natural environment are also impacting the city and some are even amplified by the city. The project frames the design as an extension of this science-landscape but focusing on the city as a site (or collection of sites) and positioning city-based practices as agents in these climatic phenomena being studied in the surrounding area. Snow maintenance shapes the cultural and ecological landscape of Utqiagvik. Spatial practice could preserve vulnerable permafrost and generate new social spaces across the seasons.

Northpole is where the sun does not set over the horizon. In the summer, the sun rises all the time without sunset. Even at night, the sky is still bright.

The night is very short because the sun passes the horizon in a quick moment. Solstice is when the day is the longest, and equinox is when the day and night time is equal.

The length of day is shorter than two examples above. The time that the sun over the sky is short. At the equator, the legnth of day is 12 hours.

Recreation Island Resilience 02

Site Joice Island, California

Area 46,175,517 ft² (4,289,850 m²)

Instructor Nana Last

Keywords brackish water, hunting recreation, sea level rising, vegetation resilience

To keep the balance between utilization and restoration of ecological landscape, the vegetation stability in Joice Island has been threatened from intrusion of salty water via sea level rising and significant human interruption by recreation. While professional silviculture BMPs(Best Management Practices) are required, making an induction of how the flora looks like is helpful to make further strategies. I did supervising classification training via ArcGIS Pro from the samples when significant utilization kept going back in early 2000s. Sea level rising is based on regression model so that intrusion would be increased without any management systems. Extrapolation mapping might be a basic resource for a response to vegetation resilience in Joice Island.

Project Description

Joice Island is a human-made island located in San Francisco Bay, California. The island an artificial wetland and an estuary connected to an artificial patch (city landscape, Suisun City). Under the influence of contiguous tidal network, climate change has significantly impact the water temperature and leads to sea level rising. These environmental changes require extrapolated management in forestry and marshland. Furthermore, the island’s flora is affected not only by climate change but also by cultural intervention: the CDFW (the California Department of Fish and Wildlife) certified the site as the wild pig hunting place. Joice Island has held pig hunting festival in 2002, 2003, 2006, 2012, and 2017. The festival is not only for pig hunting, but also for deers and ducks; therefore, a significant number of biomass cannot help being destroyed. For sustainable plant management adapting to human use and climate change, this project seeks to prepare for extrapolate plant mapping in terms of these two factors: environmental changes and cultural intervention.

Method

The scenario mapping is based on two layers: cultural intervention(hunting festival) and climate change(surface temperature of sea). The extrapolation has followed trained data from the past; therefore, supervised learning for NDVI (Normalized Difference Vegetation Index) may be conducted first. Since Joice Island already has experienced how the frequent hunting festivals had given negative effect on island flora in early 2000s, the dataset this time can be a good exemplar to demonstrate human intervention impact. Climate change layer should be related to sea temperature based on Landsat from USGS (United States Geological Survey). The relationship between heat mapping and NDVI changes should be trained as a supervised learning to show extrapolation mapping. These two trained datasets may imply scenarios: how much human intervention can be applied in the future and how many Celsius degrees the island can handle in a year.

Argument

Climate change and cultural interventions disrupt structures of flora and ecosystem service. Climate change may help the island be vulnerable to sea intrusion within the vegetation patches. Cultural interventions such as hunting festivals will bring about extreme use of carbon energies, pasture destruction, and ecosystem imbalance. Those two increasing stressors weaken plant resilience. This is the argument I am pursuing from this project, suggesting how much the landscape can withstand against rising temperature(climate change) and human abuse of nature(cultural intervention). When the stress is applied within a landscape, the stability of plant patches, matrix and wildlife is threatened. Flora and fauna that experience these changes in this purview create transition of ecosystem, and humans can no longer use the space sustainably. If humans look for continuous use of the site (Joice Island) in the long term, I argue to find the right negotiation point is imperative.

Proposition

This study intends to propose a wise flora management award for maintaining the continuous use of artificial islands and sustainable cultural recreation. Coexistence between keeping nature and human intervention is the goal from the California government. Joice Island is a human-made island created at the provincial level to provide urban residents with wildlife recreation. However, in the early 21st century, poor climate preparedness and frequent hunting festivals suggested the need for active flora management. In other words, the test is required for the Island when it comes to how the current framework should proceed in a changing context. The extension of this framework will provide a supplementary basis for other recreational islands management in California.

Submerging Island 03

Site Kent Island, Chesapeake Bay Area 8,389 ha (83.89 km²)

Instructor Brian Davis + Bradley Cantrell

Keywords sea level rising, bird migration, climate change, extrapolation scenario

Kent Island, the largest and most thermally vulnerable island in Chesapeake Bay, is in danger of disappearing from history due to climate change despite its outstanding ecological and cultural value. Extrapolatedly, the island is inferred that sea level rise and ocean current energy instability will also be affected by pollutants from the Mainland. The purpose of this project is to use the plant’s purification and soil conservation capabilities to mitigate wave energy and purify floating pollutants in the water. Speculatively, the design strategies are divided into three: from 2020 to 2040, from 2040 to 2070, and from 2070 to 2100. Securing a sustainable ecosystem not only prolongs the lifespan of the island, but also creates a bioprotective landscape as a major hub for migratory birds.

Timeline of Coastal Line Changes

Chemical fertilizer and its contamination within Chesapeake Bay is highly related to policy systems and regulation. Pollution may accelerate eutrophication and micro-organics within the sea, getting sea more heat energy warm enough to be vulnerable. The shoreline of Kent Island has been setting back compared to 50 years ago. Extrapolation of future shoreline without any human intervention poses a threat to danger of submerging island. Plus, migratory birds depend on the islands as a resting hub; therefore, resilient design is required for biohabitat ecology.

Phase Approach to Coastal Alteration + Ecological hub

Topographically the island is already being cracked by erosion. Suggesting this alteration as an opportunity to create bird islands sepearte from human intervention, the abstracted island can be protected from vegetation planting and coastal infrastructures. First, inducing wave flow into edge of prominent part is conducted for twenty years. Second, birds have more safe condition to take a rest abstracting from humans. Bridges might provide affordance for visitors to observe migratory birds and changing landscapes with little affecting ecological systems.

Topobathy Wrangling 04

Site Smith Island, Chesapeake Bay Area 4,596.15 ha (45.96 km²)

Instructor Brian Davis

Keywords CMS Wave, topobathy data, scenario extrapolation, sea level rise

Topobathy is measuring and recording three distinct surfaces (land, water, and submerged land based) sensors. As a supplementary tool of Geographic Information System, CMS is a software for coastal resilience, building capability to visualize scenarios of shorelines. It may help island communities bounce back after hazardous events such as flooding, hurricanes, coastal storms. The goal of this project is to figure out which intervention is effective toward hazards: infrastructure (breakwater, dikes) or marshland (buffer zone). A green infrastructure approach to coastal improvement might be operated by using plants, reefs, sand, and natural barriers to reduce erosion.

Why does it matter?

Smith Island is a low-lying area composed almost entirely of marshland, with a land level of less than 1.2 m. The communities of less than 300 people (Ewell, Rhodes Point, Tylerton) living on the island are greatly affected by sea wave and wind. Influenced by river currents(Potomac, Rappahannock) from Virginia, the main wind direction also faces east Maryland. In the last 15 years, various administrative organizations have intervened on the island to protect the coastline from erosion/weathering and restore wetlands. Funding comes from the US Army Corps, the Maryland Department of Natural Resources, and the Maryland Department of Housing and Community Development, which mainly manage jetty and expanded marshland near the shoreline.

Erosion and Deposition by Marshland (refrence: US Geological Survey) Moderately high dunes here were eroded and overwash transported sand inland. Marsh and marsh channels were buried.

SCENARIO 3 WITHOUT MARSHLAND

Sea level rise is a serious problem because the weight (potential energy) of the rising wave is converted into kinetic energy even when solely several centimeters are heightened. In particular, the ground of Smith Island is so low that most grounds are covered up of marshland, and the central current of Chesapeake Bay, deep water, exists within a short distance. (The greater the wave energy at the depth of the water, the more destructive force on the island.) As a result of comparing the scenarios, the removal of marshland caused the highest sea level rise, and the wind direction was natural/artificial, and it showed the characteristic of north-facing winds.

Brentwood Investment Brief 05

Site Brentwood, Washington D.C.

Area 142.78 ha (1.43 km²)

Instructor Ian Klein

Keywords affordable housing, post-industrial, environmental justice

Brentwood is black-dominant community within Washington D.C. An industrial zoning has affected environmental justice issue in terms of affordable housing and amicable living conditions. While highly depending on BET headquarter, the demolition of its business posed a threat to black community. Suggesting new zoning system to maximize the potential of restoration, the project aims to balance between sustainable housing systems along with multi-functional buildings.

*Group work with Thomas Brown, Caleb Sica

History of BET

Accumulated trajectories of black communities have been strongly developed in Brentwood. Black Entertainment Televeision Headquarter played a pivotal role in creating blackoriented culture within the site. However, from 2000s the enterprise was on the verge of collapse, resulting in closing a business in Washington D.C.

Project Narrative

The goal of this project is to build a modern cultural hub on a historically significant site within an underserved opportunity zone in the Brentwood neighborhood of Northeast DC. It will service the needs of the community with affordable housing, community space, transit improvements, & a partnership with Howard University. With over 8 acres of space to redevelop, it has the rare opportunity to execute a master plan with office, retail, and multifamily where all of our tenants needs can be met in the new 15-minute city.

The prevailing PDR (Production, Distribution & Repair) - 4 zoning maximizes the potential for commercial and industrial uses while discouraging residential development. Within the PRD-4 zoning we currently have three individual parcels, it can maximize the commercial uses, particularly office & educational between the three existing structures - BET former HQ, studio space, and warehouse. The goal of PDR zoning is as follow:

• To permit high-density commercial and a large workforce

• To make heavy machinery under controls that minimize any adverse impacts on adjacent

Proposed Zoning Argument and Rationale

Mixed Use-6 ZONING

The Mixed-Use (MU) zones provide for mixed-use developments that permit a broad range of commercial, institutional, and multiple dwelling unit residential development at varying densities. The MU-6 zone is a mixeduse zone that is intended to be applied throughout the city consistent with the density designation of the Comprehensive Plan. The MU-6 zone is intended to:

• Permit medium- to high-density mixed-use development with a focus on residential use

• Provide facilities for shopping and business needs, housing, and mixed-uses for large segments of the District of Columbia outside of the central core.

Digging into Microclimate 06

Site Observatory Hill, Charlottesville, VA Area 1.98 ha (19,834 m²)

Instructor Leena Cho + Mathew Siebert

Keywords moisture, light and shadow, abstraction, seasonal change

The purpose of this project is to create different microclimate zones by manipulating energy componenets with vegetation and landform. O-hill is located in the middle of hydrological cirulcation with rich vegetation resources. Desinged landform, the berm which has different slopes and height, makes enclosure or openness of the space. Cold water tedns to collect in depression or dips in the land with narrow entrances. Wind is able to be turbulated or blocked; the direction has changed. Vegetation is also a significant ecological agent to regulate flow of this energy, regulating sunlight absorption and transpiration. Following the sequence of the circulation, humidity and temperature has changed: Enfold Plaza(warm+dry), Soggy Area(warm+humid), Frost Pocket(cold+humid), and Lichen Meadow(cold_dry).

Plant is an organic material which produces or saves energy by photosynthesis. Light is an imperative resource to obtain metabolism activities while casting shadows underneath. Forest stratification is a result of competition among species to survive. While canopy trees preempt beneficial hierarchy to receive direct sunlight, undertrees or shrubs find niches. This composition fullfill the vegetation density in volume, casting shadow over and over. Shadows are also influential indicator to change temperature in micro-scape.

Plant structure has a significant influence on environmental stimulus because it has energy dynamics, organic activities and do metabolism. Transpiration is the process of water movement through flora, and this feature affects(sometimes dominates) the slight idfferences of surrounding. From leaves, stems and flowers, evaporation imparts the energy to atmosphere and process hydraulic conductivity of the soil. The idealized condition for active transpiration parallels with physical dehydration: warm, dry, and windy. Therefore, experiment for this project hypothesized that the sparser the vegetation, the more transpiration.

Catalogue of my experiences 07

This chapter is to introduce myself which has not been covered from previous pages. First, I am genuinely interested in water management issues within the city in terms of cartography and data analysis. Mapping is helpful to digest cities and communicate with stakeholders, policy makers, and environmental planners. Second, hand-drawing is another tool for me to capture the momentary or microclimate environment. Organic cities are fluctuating, and extracting observation is significant. Third, instructor experiences are what I care about the most in my history and for my future career. I enjoy the process to prepare for the lecture and interact with students. Fourth, traveling is one of my favorite hobbies and one of opportunities to grow up once again. Documenting unfamiliar places enriches my perception to the world.

Comparison of ten Water Stress Cities

Water-stress city is where the water resources in a city are insufficient for its needs for decades. Before digging into water issues in Jaipur, India, I have studied about ten water-vulnerable cities in the world: Sao Paulo (Brazil), New Orleans (LO, US), Los Angeles (CA, US), Cairo (Egypt), Casablanca (Morocco), Cape Town (Republic of South Africa), Bangkok (Thailand), New Delhi (India), Mexico City (Mexico). According to water infrastructure, topography, and population, each city has its own reason suffering from lack of water. Mapping was helpful to figure out water resources and residents’ reliance on features.

| Hand-drawing

For me hand-drawing is distillation of my perception or cognition of landscapes so that I can reiterate my thinking in a tangible way. Drawing is another opportunity of recognition about aesthetic moments in the city. Even soil, hardscape, vegetation, and building materials are different day by day; the weather, erosion, and human intervention are indicators within this changes. I am fascinated by how time-series has provided versatile momentary landscapes. Also, the alignment between structures and natural resources is reminding me of combination of mateiral palette when I design urban morphology.

Teaching Experiences

I am always grateful whenever I interact with my students, learn about what they want to pursue from classes, and help them achieve their goals. Building rapport is imperative as if I am getting to new people. Since 2018, I have worked in education industry, teaching undergraduate and high-school students. I did teach community engagement, field survey, coastal resilience, urban analysis, academic writing, GIS mapping, and design studio. Creating materials and feedbacks is where I can develop my creativity and be humble again in front of academia. Back in the University of Virginia, I have worked as a student instructor assistant almost every semester, participating in curriculumn with faculty.

Travel is always my favorite!
