Abstract
In April 2007, Mayor Bloomberg’s office released PLANYC, a comprehensive blueprint for making New York City sustainable in the year 2030. In that plan they recommend an extensive green roofs program as a means to reduce storm water overflows, reduce CO2 emissions and modify the urban heat island effect. Earlier, a memo from the city’s Department of Design and Construction (DDC) came to the conclusion that extensive green roofs may not be cost effective for the city. The authors examine the various points raised in this memo, as well as others that were not considered, and come to a different conclusion than that of the memo. The memo does not address a number of potentially significant issues, such as potential public health benefits.
