Mexico City functions as a hallucination, inviable in theory, 20 million people manage to thrive in a muddy old lake bed. Too much water in the rainy season, too little in the hot days of summer. Finding new methods of battling a worsening water crisis is paramount. In response, a new infrastructural animal is allowed to grow on the flanks of the city, a new urbanism of taut functionality built on the banks of the River Beccaria. Driven by necessity, guided by basic needs, the animal lifts itself up, crusted with a new barrio of winding stairs and waterfalls, dripping with pots of vegetables and fruit. Underneath a new aquatic landsape of cypresses and water lilies is created, large ponds and narrow streams capture clean and store water.
