Cocaia and Nova Grajau within the Billings Reservoir System

A prototype of ecological housing and land remediation on a local scale in Cocaia + Nova Grajau is an example for other sites on the Billings Reservoir. It restores the water quality of the entire reservoir through 3 local stages of natural remediation, while redirecting floods + storm runoff  through street trails, housing tiers + reservoir burm islands. Incorporating new housing, recreation and wetlands, this site is an integrated network of improved living and leisure.
