PLAQUEMINE LOCK

Reconnecting the Basin Between Two Levees

Envisioning the Mississippi as a Living River

Summer 2021 Location: Plaquemine, LA Team: Belina Yi, Huiya Zhong, Luchen Liu Commencing at re-purposing the historic Plaquemine Lock from an engineered device to an ecological one, we envision a great shift of eco-economy in the disconnected Basin between levees of the Atchafalaya River and the Mississippi River. With interventions systemically impacting on different levels, we will reconnect people and isolated water bodies.

The Basin In-between is Disconnected The basin Plaquemine lying in is not enclosed by natural dividing range but by levees. Protected by the levees along the rivers and supported by the pipelines in the Wetland, the Basin in-between was planned to expand agricultural and petrochemical industries along the Mississippi River.

The basin Plaquemine lying in is not enclosed by natural dividing range but by levees. Protected by the levees along the rivers and supported by the pipelines in the Wetland, the Basin in-between was planned to expand agricultural and petrochemical industries along the Mississippi River.

Although the agricultural attempts in the Basin failed, it still permanently created an unsustainable separation of the landscape across the levees, highlighted by refineries and farmland on the east side and wetland forest on the west side. High banks along the river and canals prevent the natural overflow of river water into the back swamps. As a result, the disconnected water and sediment go wrong, causing semi-permanent flooding in the upper Basin and land loss on the coast. At the same time, the runoff and atmospheric water pollution caused by agriculture and refineries along the Mississippi River cannot be filtrated naturally by the Wetland.

If No Action is Taken The lush-looking Basin is now a stagnant “museum forest.” Without action, the whole Basin will be submerged, facing climate change. And the natural services of water filtration, carbon capture, and wildlife habitat will disappear in 50 years.

& RESORT

Reopen the Lock and Water Management The lock no longer functions as steps for shipments but a dynamic water control, with the rotation to accommodate the volume of waterflow from the Mississippi River. We repurpose the lock constructions to be a museum to exhibit the process of hydrological engineering, to raise awareness that water is life.

Vertical Crawfish Farming Cluster Based on the seasonal flooding cycle provided by the water management system, crop-crawfish rotation farming could develop along the bayou. In the flood season with abundant rainfall, local communities can enjoy crawfish harvest, and the rice harvest happen in dry seasons.

We encourage the community to welcome new form along the bayou also in the wetland.

Imagine a new ecosystem in the long run with wild crawfish driven tourism economy.

INDUSTRIAL HERITAGE HABITAT Pittsburgh - Manchester Chateau

Industrial Heritage Habitat

Spring 2021 Location: Pittsburgh, PA Team: Kai Zhang, Huiya Zhong, Yong Zhuang We imagine an alternative, habitable future in Chateau, an underutilized industrial neighborhood filled with warehouses and parking lots. We’re proposing to restore the urban vitality that existed before large parts of neighborhood, which were demolished for Route 65.

Bringing back a human-scale street grid that supports smaller building footprints can accommodate makerspaces, local business, community culture, and green innovation programs. We preserve and upgrade existing buildings to make this place be welcoming to a new population and long-time residents alike.

The north shore of the Ohio River segment, specifically the Manchester/Chateau Neighborhood, is a post-industrial district that was physically dissected by the route 65. On the west side of the route there’s Chateau with the majority of industrial zone. On the east side, there’s Manchester with mostly residential units and some commercial and civic programs.

Study of Historical Fabric, Fragmentation, Environmental Condition and Waterfront In the first half of the 20th century, it was mostly occupied by smaller scale residential units, Then the concrete aorta plunged across the neighborhood, and separated the area into two pieces. The part closer to water had adopted a much bigger fabric. The existing warehouses, coupled with the highway and parking lots, cause poor air quality throughout the region and specifically in Manchester-Chateau.

Transition Process of the Wellness Promenade Decrease the capacity of the highway to 50 percent, and determine the thread of the promenade that goes across the connection, and let the way find itself towards the river. The new programs would emerge along with a smaller and more human scale presence. Finally, fabric reached to the waterfront and back to the highway, which creates unique experiences of the connection and the terminal.

ENERGY JUSTICE NOW

Community Participatory Algae Industry

Fall 2020 Location: Inwoods, Harlem River, NY Team: Cheng Ju Lee, Aruna Ananta Das, Lijing Yu

Energy Justice Now

To build a community participatory algae industry and create a energy justice, greener future, and depending on the power of people. In the future our vision is to attain 100% Clean electricity by 2040. We intend to achieve this goal by introducing electricity produced by algae. We cannot change the past, but we want to work with the community to change the future.

Eco-economic System: Self-sufficient Algae Industry and Local Free Energy The project introduces the whole algae process into three areas covered all of the Inwood, including cultivation hub, manufacturing, and residential area. We will get a 40% energy discount and at least 100 job opportunities from the establishment of the cultivation hub. Create 200 job opportunity and 1.5 million per year of operating revenue in the manufacturing area through the local factory, business, and algae farm. Then, there will be 60% public space renewed for our community.

Concentrated Power Generation The cultivation Hub offers the infrastructure system for this pilot project to work on. Since the existing site already exist the parking service, we’re building a concentrated algae cultivation here to absorb the carbon dioxide emitted by the garbage cars and buses. Make use of the waste water to offer nutrients for the algae and the waste water will also get purified.

Community Participatory Algae Farm Introducing algae farms in the waterfront so people could take part in the process of producing electricity which would help reduce the cost of electricity for the community. This also gives us the opportunity to introduce the community to Algae farming and how that can help them create clean electricity because without an aggressive commitment by the community it will not be possible to achieve carbon neutrality by 2050.

Household Alage Installations If community members want to rent their housing façade to get more profit, they can buy the low-cost algae panel prefab from local manufacturing and project also encourage them to help neighbors to install those panels, with bouns of the discount of electricity.

Algae Byproducts Temporary Market As we producing algae by-products in our local industry, we will organize periodic markets in public space for community to sell and buy anything they need. Both local factories and individuals can have their booth.
