As part of Chongqing OCT’s cultural and tourist project, the OCT Riverside Recreation Zone is an ecological park project neighboring the Jialing River and closely connected to surrounding communities. With a 1,500m long riverside interface and a 40m height difference, the Zone has a distinctive feature of terraced fields, which is typical of Chongqing.

The site belongs to the scope of the Jialing River Ecological Corridor. Before renewal, the sidewalks on the site were narrow, and the viewing platform and steps had been eroded by regular water level fluctuations. Piling sediments and rampant weeds become barriers on the roads and undermine the visitors’ experience. It fails to function as an urban recreation zone by the river.

After renewal, the Zone not only services the communities nearby, but functions as an urban recreation zone by the river. At the same time, it connects the Lijia and Yuelai riverside zones together, and improves the recreation zones along the Jialing River. The site enjoys excellent ecological base, with the native plants being well preserved. The terraced fields form natural landscapes. The riverside wetlands ensure the water eco-recycling of nearby areas. All these elements provide favorable conditions for landscape design.

For a public space with extensive natural elements, the most important task is to minimize intervention. Rich natural landscapes should be presented on the basis of ecological protection. The first step is to preserve the original landform of the site, including the terraced fields and bamboo forests. Not much adjustment is made to the elevation. The designers wish to preserve the original site as complete as possible.

As the site is located in the water-level-fluctuation zone, the designers need to pay special attention to the durability of materials used and the plant type. Natural materials that require small maintenance costs and are erosion-flood resistant are used to build recreation sidewalks, roads among terraced fields and riverside runways.

Plants in the water-level-fluctuation zone play an essential role to connect the water-land environment and to sustain the ecological balance. Plants that grow both on land and in water are grown among the terraced fields, with the raised path among fields functioning as the natural sidewalks. Flowers that grow both on land and in water have ornamental values on one hand, and can recover from floods easily on the other.

The designers review the original bamboo forests and introduce aquatic plants to the wetlands, thereby protecting the habitats of wild species. Trees like metasequoia and ginkgo are planted in the open and elevated areas.

Apart from protection and restoration, the designers need to turn the site into a public recreational space by introducing recreational functions and improving site accessibility and comfort.

The entrance of the site is situated along the riverside avenue and the highest position. Based on the terrain and the plant structure, the Z-shaped bridle path that reaches the river is designed. It stretches to the Lijia and Yuelai riverside recreation zones, and becomes part of the Jialing River Ecological Corridor.

The west-faced site is an ideal choice to enjoy the river views at sunset. Along the bridle path are various viewing platforms. In the site, there are overhanding corridors, small corners at the cliff and seats under trees.

The children’s space is designed based on the legacy of the site. In the past, the farmers once raised cows in the areas with lush vegetation. As time passes by, the land becomes uneven as the cows treaded on it. The designers keep the original landform and simulate the scene where the feeding bottle is knocked over. As the milk flows into different directions, the fun of the children’s space is thus presented.

In this project, top priority is attached to site protection and restoration. With respect for the natural ecosystem, original landform and cultural legacies, interactive design that serves recreational, sports and social purposes is presented. The creative design encourages engagement, restores the vitality of the site, and becomes a public space for the nearby residents again.
