Water CityBetween flood plain and safe grounds
Water City is a completely new urban-rural setting rising to the west of Hanoi. Since the Day and Tich Rivers are again following their natural flow, a large flood plain park extends around the city. Connected to this are irrigation canals, drainage ponds and the presence of large edge lakes. A carefully designed dyke (with both hard- and sotf-engineering) deals with the protection from floods of selected settlements that can remain in the naturally floodable area.
The tool of cut & fill is used to change the topography of the site. The basic idea is to divide the site into finger-like plateaus, their height depending on their programme and their relation to the ladder road network connecting to Hanoi via two radial roads. The development of a very dense and high-rise urban area is envisaged taking place only near the two radial roads. Low lands are optimized either as productive fields, recreation areas or as water purifying urban wetlands.
