Detention Community

Create detention space with water cells that help to store the urban overflow.

The existing community mainly manages the water flow in the road system that set bioswale and water cells in the middle. When there is too much water flow from outside, the water cells separate the outside flow and the local flow and temporarily store them.

The newly developing community mainly rise the first floor and leave the ground floor for the public and flood. I set the water cell at ground level and Voronoi structural water tanks underground. There are check valves between the tank and the cells as well. When water full-fill the tank, it will flow into the cells while the cells work as resurrection fern that extends with a hierarchical structure. On the other hand, the water tanks also enhance the soil structure that decreases soil liquefaction risk.

During the heavy rain, water flows to the central detention communities after the transportation by the drainage system. They first go down to the water tank, while people still have time to prepare for flooding, such as set water cells, and check the water stage at bioswales. As the water flow in continually, water fills the tanks and start pumping to the water cells by potential energy. At this moment, the public space becomes detention space. The water is kept in the cells instead of flooding anywhere. Moreover, the top surface of the cells potential to keep the transport-ability for the communities. After the flooding, the water could be reused by the citizens for daily life.

Detention Community

The park helps slow down the flow and delay flood peak by the meandering water routes and J-Hook Van.

The bio-swale connect the communities, the river park and the water tanks. It helps to keep, collect and transport water.

The multi-level of waterway helps to control water speed and reduce drainage stresses. It also creates a hydrophilic space for the public. The smooth pavement is human-friendly design for multi-activities. Furthermore, it promotes the ground to absorb water.

During the heavy rain, the river park works as buffer protection; the multi-level waterways help delay flood peak. It also works as detention space, holding water if the water is flowing into the community beyond the limitation.

Furthermore, during the regular day, the grassland will be covered by tidal regularly like a WETLAND. It provides the chances for mangrove ecosystem extension. I also create a space for the public to be close to water. The activities change as the tidal. During the high river stage, people can bike on the routes and appreciate nature changes. During the dry, people are allowed to swim in the stream. They can also jog, or picnic or other activities on the grass. The park not only works as a flow manager but also a parent-child educational park. It enhances the public’s sense and knowledge of water. It also helps to improve collective engagement.

This function achieves principles about adapt to a changing condition, locally attuned and responsive, and resource-efficient.
