Spring
Responding to the issue of water pollution, homelessness, and lack of park space in Los Angeles, land on water use water dams and 3 scales of on water platforms to treat water pollution and create accessible recreation space. It adds shade, public access, and programmingto the River

Create community space
Add shade along the river
Hopping Islands are floating platforms that activate river space as gardens and board walks. It could become mobile by tow boats for community events along the river. It could be either placed together to form a larger open space or horizontally to form a continuous path.

Floating Wetlands is a type of “river-ponics” that applies the principles of aquaculture and hydroponics. It’s capable of creating an intensive wetland effect, remove pollutants and suspended solids. It could be installed on a wide range of water depth and tolerate constant flutuations in water levels.

02. EXPO 2025 Location: Chicago, IL Studio Project 2017 Fall Analysis: Collaboration with Ziyu Wang, Xueling Hu
Historically, due to pollution and untreated runoff, biodiversity in the Chicago region has been in decline. But an ecosystem could not be sustainable without biodiversity. The design is an Expo of ecological processes in what it used to be the Chicago wilderness along with people’s role in sustaining this hub of biodiversity. In this plan, we intend to achieve this goal through three strategies: Preserve, educate, and provide.

04. Adapting the Riparian Corridor of the Little Calumet River Location: South Holland Studio Project 2018 Fall Analysis: Collaboration with Ziyu Wang, Xueling Hu Design: Collaboration with Maxwell Stuber, Sean O’Connor, Amanda Lerman
The main hope of the design is to reconnect the community to the river and adapt Little Calumet into the identity of South Holland. To reconnect the community, the group came up with prototypes to deal with flooding. Then, the riparian corridor is connected to present parks, bike trails, and churches through a continuous park and trail network. A specific theme is chosen for each site to integrate the riparian park to the city and emphasizes its identity as part of the life and history of South Holland.

Prototype: Pool Undulating landscape increase run-off distance for more flitration and ground water recharge. The topography is reinforced at the bank with rip-rap to decrease soil loss.
Prototype: Meander Meandering river reduce the river speed and increase distance of waterflow, metigate flooding.
