Mexico City, a city that was once built on a lake, is today heavily affected by water-related problems. The project is intervening in the Laguna Mayor regulating tank located in the eastern periphery of Mexico City called Iztapalapa. In this densely populated urban area, cyclical flooding and water shortage are among the most pressing issues, along with ground subsidence. Instead of 20 hectares of the existing empty landfill sitting in the centre of the neighbourhood, the project proposes an alternative flooding alleviation landscape, using sustainable urban drainage for rainwater harvesting and absorption and wetland creation. The core wetland is left untouched for natural development and habitat creation. At the same time, the project's perimeter is intended for user inhabitation and appropriation by the local community, combining contemporary water management techniques with the vernacular agriculture tradition of growing crops in the shallow ponds, called chinampas.
