Revitalizing Urban Life [Academic and Individual Work] Project Topic: Urban City Development Project Location: Georgia, USA Date:10/2019 Institution: The University of Georgia Instructor: Donnie Longenecker Obesity is pravalent in Dooly county due to insecured food sources and inadequate city development. Dooly county has about 23% of population in poverty, where fast food and frozen food are the main nutrition intake. Cities have very limited pedestrian walkway and bicycle lane, as well as exercise field. Therefore, citizens are less likely to walk outside for exercise. The site in Vienna was chosen for its moderate wide road and open spaces that can be redesigned. Which would transform Vienna by connecting people and places using alternative transportations. More than just free, accessible trails where people can exercise and commute. The project’s goal is to create dynamic, inspiring spaces and serve as gathering space that encourage collaboration and city identity.

Eco-Revival [Collaborative Work] Personal part: 45% concept and design, 40% graphics Project Topic: Brownfield Regenration Project Location: Chengdu, China Scale: 65 ha Date: 08/2020 Chengdu, where the site locates at, now has more than 16 million resident population, and produces 17,000 tons of garbage every day. With the high increasing rate of garbage production, the existing landfills in Chengdu are almost full. Which means looking for a large volume landfill is in urgent need. The site was used for sandstone exploitation. In 2007, the mining work stopped, and left the abandoned qurry a complex topography of scarps, grooves, and platforms. Which is large enough to hold about 20 years garbage landfill. The project aims to make use of the garbage reuse to rebuild the terrain and revitalize the site. The goal is designing a sustainable and ecological forest, a solution for mine reconstruction.

Ecological destruction due to inappropriate waste dumping Inappropriate and possible illegal dumping can cause ecological damage in the area and its surrounding environment.

Soil Pollution Inappropriate landfill generate leachate to the ground, causing water pollutions and soil pollutions.

SITE CONTEXT
Chang’an area locates in between the the suburbs of Chengdu city and Longquan Mountains. It was an sandstone quarry for the past 25 years. Now the site has been abandoned and no further plannings.
PROCESS OF GARBAGE REUSE
Rebuild the terrain and revitalize the site by making use of the city garbage. Classifying waste and reusing them in the process of landscape regeneration.

There are two proposed strategies corresponding to each slope gradient range. They have similar preparations before planting plants. Rebuild the pit and slow down the steep slope by using the landfills to build retaining wall, grass slope. Later, using ecological method to restore the site.

Resilient Semarang [Collaboration Work with Hanlin Jin] Personal: 90% concept and design, 70% graphics Project Topic: City wetland, Flood control Project Location: Semarang City, Indonesia Date: 12/2020 The City of Semarang, as major port city in the Central Java province in Indonesia, has developed rapidly for the past several decades that industry and business increasing dramatically as its population striking. The urbanization induces more water resources demand, and land exploitation. The consequences is the more groundwater extraction, the more land subsidenced. Which leads to more intense and frequent flooding during the rainy season. Due to its location, Semarang are facing more serious flooding issues, and affecting local people’s regular life. This project mainly focus on the East Canal and its surrounding areas. The selected site are designed as wetland and natural restoration area. Porous grass terrace along the canal abosorb the overflowed water. Grass hills can resist the water rising and submerge the residence area. Water retention basin can store water while the grass hill obstructed the water from upwards.
