New York City stormwater is a major cause of water pollution in the harbor and estuaries. This is due to the vast areas of impervious surfaces (e.g., rooftops, pavements, sidewalks) that rapidly shunt runoff into the combined sewage overflow (CSO) system. Green, vegetative roofs may offer one of the most effective methods of distributed stormwater control to help abate this pollution.

In this report we quantify that storage capacity for a modular green system installed on the Con Edison Learning Center in Long Island City, New York.
