PROJECT NAME:

FOOD CO. AN INDUSTRIAL COMMUNITY WASTE STREAM: REGENERATION OF CONTAINERS

LOCATION: Seattle, Washington, US.

TYPE: Group Work

TIME: 03/2022

Duwamish is a neighborhood located southwest of Seattle. The neighborhood is surrounded by Seattle's industrial community. Due to this historical background, many containers circulate and go unused in the area each year.

The project aims to use the existing containers on the site to create facilities to serve the residents in the public spaces within the community to meet their needs for public space. During the meeting with the client, the client proposed to improve the public transportation system. The project continues with the design. Using Foodlifeline as the design site, the project extends Duwamish's sustainable waste disposal and community service design principles.

01

The Georgetown Steam Plant, located near Georgetown in Seattle, Washington, was built in 1906 for the Seattle Power Company to provide electricity to Seattle, especially streetcars.

Boeing Plant 1 was established on the Lower Duwamish in 1916

1855 The Coast Salish people living in the Duwamish-Green Basin signed two treaties with the Territorial Governor, Isaac I. Stevens (1818-1862), ceding the land and establishing reservations, but reserved the right to hunt, fish and gather for the indigenous peoples.

In 1895, Eugene Semple, who had earlier served as Governor of Washington Territory, outlined a plan for a series of major public works projects in the Seattle area, including the straightening and dredging of the Duwamish River, both to open up the area to commercial use and to alleviate flooding.

By 1920, 4½ miles of the Duwamish Waterway had been dredged to a depth of 50 feet, with 20 million cubic feet of mud and sand going into the expansion of Harbor Island. The shallow, meandering, nine-mile-long river became a five-mile engineered waterway capable of handling ocean-going vessels.

European Americans arrived in the area in 1851 and were eventually settled by whites. The Duwamish people continue to work and fish in the area. But by the early 20th century, most of the remains of traditional life along the river had disappeared. The Duwamish basin industrial and commercial included cargo handling construction, ship concrete manufacturing, fabrication, food processing, other industrial operations.

Boeing Plant 2, further upriver, in 1936.

basin soon became Seattle's commercial core area. Activities handling and storage, marine and boat manufacturing, manufacturing, paper and metals processing, and countless operations.

The EPA declared the Lower Duamish Waterway a "superfund" site in 2001, meaning it was eligible for a special federal cleanup program due to the severity of its pollution. The EPA manages the clean-up of sediment in the river, and the Ministry of Ecology controls the sources of pollution in the river. The City of Seattle, King County, the Port of Seattle, and The Boeing Company unite as the Lower Duamish Waterway Group (LDWG).

Industrial development has resulted in the contamination of waterway sediments (river bottoms) with toxic chemicals from a variety of sources, including stormwater runoff, wastewater, and industrial practices. Most human health risks come from polychlorinated biphenyls (PCBs), arsenic, carcinogenic polycyclic aromatic hydrocarbons (cPAHs), and dioxins and furans.

PROJECT NAME: EARTHWORM & P-PATCH FARM REBUILD PROJECT

LOCATION: Seattle, Washington, US.

TYPE: Group Work

TIME: 01/2022

The site is located northeath of UW. The project has three strategies which are smart agriculture, educational farming, and ecological cycle. Create the bottom decomposer in the farm ecological chain through the cultivation of mushrooms and the feeding of earthworms. Cooperate with surrounding farms to achieve product recycling and waste utilization. Taking "food" as the theme, it integrates various experiences and entertainment to create an agricultural landscape experience, and education base. Jointly develop with technology companies, start "Future Farm", and establish a complete set of intelligent agricultural management monitor their farmland in real-time through technology.

INDUSTRIAL COMMUNITY COASTAL LANDSCAPE PROJECT LOCATION: Seattle, Washington, US.

TYPE: Group Work

TIME: 09/2021

The project is located near Salmon Bay. The project is committed to building an interactive place that showcases the surrounding ship culture and ecological environment. The project will solve the problem of pedes- trian fow obstacles caused by the subsidence of the existing plots and increase the influential building groups in the site and the connections between them to realize the efficient use of the site, improve the crowd the community, and the location. Link. The proiect also designed corre- sponding rest areas and viewing areas for the flow of people and con- nected them to the building to form a whole regional interactive viewing place.

PROJECT NAME: "BLUE TEARS"THE TRANSFORMATION AND REGENERATION OF THE ISLAND PROJECT LOCATION:

Jidiao island, Fuzhou, Fujian, China

TYPE: Individual Work

TIME: 09/2020

AREA: 239.64 Acre

Fujian Jidiao Island is located on the southeast coast of China, adjacent to the Taiwan Strait. Every summer, in the ocean near this island, there will be luminous sea water. The locals call this phenomenon of ocean glow "blue tears." In recent years, the cause of this luminous sea has also changed from harmless marine luminous organisms to luminous algae, which will compete for marine resources. The project attempts to design an ecological installation landscape to help filter harmful noctilucent algae in the ocean and stabilize the existing marine ecosystem. The designed ecological reef island will also provide an interactive viewing experience for the area.

PROJECT NAME: LANDFILL REGENERATION PROJECT LOCATION:

Haidian District, Beijing, China

TYPE: Group Work TIME: 06/2020

AREA: 91.28 Acre

With the rapid economic development, Beijing will face more and more serious garbage disposal problems. The speed of relocation of garbage dumps has not kept up with the development of the city, so that many schools have been built near garbage dumps, which is not conducive to children's health and education. The project has designed an ecological children's park for the Beijing Liulitun landfill. Use circular vegetation in the water to help treat and filter the leachate in the site. And help the ecological restoration of the site by planting plants. The purpose of the project is to help enhance the activity urban space for nearby children.

PROJECT NAME: EDOGAWA FLOOD COEXISTENCE COMMUNITY PROJECT

LOCATION: Edogawa, Tokyo, Japan

TYPE: Group Work

TIME: 08/2020

AREA: 118.72 Acre

The Edogawa area of Japan is the most flooded area in the world, especially storm surge. The storm surge will flood the local community for about a week, making local residents unable to live normally. The area of the project's sinking site with low usage rate during storms, such as a baseball field, is used as a temporary storage area. Elevate the overall community and build elevated walkways between communities with different functions to help resolve the impact of local floods on residents’ lives.

PROJECT NAME: CARNIVAL TRAIL AND CITY PARK PROJECT

LOCATION: Rio de Janeiro, Brazil

TYPE: Group Work

TIME: 11/2020

AREA: 23.52 Acre

Project background: Rio de Janeiro is the most amazing carnival project in the world. The Rio Carnival venue can only be open for about a month. The low-usage sites and the crowding of surrounding communities are the problems to be solved by the project. The project renovated the existing stands to increase the efficiency of the flow of people and enable visitors in the venue to have a better interactive experience. The urban park built on the existing open space in the site and the surplus space generated after the site renovation will help the residents of the surrounding communities use and experience the site more efficiently in a whole year.
