Blue roofs that are used for temporary rooftop storage can be classified as “active” or “passive” depending on the types of control devices used to regulate drainage of water from the roof. A number of blue roof pilot projects have been implemented around the United States. Active blue roofs for storm water detention using forecast integration were first proposed in 2008. Active blue roofs are sometimes referred to as automated roof runoff management systems. Recent work on blue roofs have involved pilot projects using stormwater collection. Blue roofs can provide a number of benefits depending on design. These benefits include temporary storage of rainfall to mitigate runoff impacts, storage for reuse such as irrigation or cooling water makeup, or recreational opportunities. Blue roofs can include open water surfaces, storage within or beneath a porous media or modular surface, or below a raised decking surface or cover. A significant blue roof pilot project intended to evaluate the potential of the systems for mitigating combined sewer overflow impacts was conducted between 2010 and 2012 by the New York City Department of Environmental Protection. The NYCDEP blue-roof projects are the first to utilize a novel passive blue roof tray design which relies on the lateral transitivity of non-woven filter fabric for drawdown control in a full scale pilot. Monitoring of these systems has demonstrated their performance as an effective means for mitigation of peak flows and alteration of timing in combined sewer systems. Blue roofs are often privately owned, and make […]
