Neat and green, Architect's News is reporting that the nation's largest green roof is taking shape atop a Bronx water plant that will double as a driving range and includes an "integrated security program for the facility below" (they say its Pebble Beach meets the Biosphere meets Rikers). The Mosholu Golf Course is run by the city’s Department of Parks and Recreation, and amidst the 9 holes there will soon be a $2.1 billion drinking water treatment facility. Construction isn't set to end until 2012, when landscape architect Ken Smith's vision of "one of the largest and most intensive green roofs to date" will open to the public as "a fully functioning driving range and an irrigation system for the golf course." In addition, the project architects at Grimshaw have also included a green roof in their design of a new clubhouse on the site. Recently Con Ed in LIC joined the small fleet of green rooftops popping up in the five boroughs.
