In Nanchang, at the delta of the Poyang Inland Estuary, the unique rhythm of water brings richness of life, and also unpredictable flood damages. RuLe Lake is a seasonal lake within Poyang Lake system, located in a valley between Nanchang City and its newly constructed airport. Due to its strategic location, there is a high demand for transit-oriented development and infrastructural investment along this foothill corridor. Similar to other regional valleys, the site is repeatedly flooded, and suffers from regular storm damage. Because the pre-existing damming and drainage channels created by local rural communities are no longer compatible with the growth, the municipality required fundamental measures to consolidate flood districts and upgrade its standards in order to protect properties and public safety. Building upon an existing seasonal lake within extreme water-level changes, the project was challenged by the tension between the untamed natural beauty and public safety. In the regional planning phase, the landscape architects worked closely with urban designers and municipality and flood district authorities to identify suitable development areas and existing natural resources, and successfully defended the ecological sensitive zones for preservation and recreation. In the site planning and design phase, the team refined the interfaces of urban stormwater green infrastructure and connected these LID facilities into the park elements. The Metropolitan Park program and amenities are carefully planned and allocated per their compatibility with drought or flood, thereby increasing resiliency, and turning the most difficult tidal zones into differentiated, celebrated lakeshores.
