“Imagine a building like a tree… A city like a forest”

Land-use classification for extensive vegetative roof acreage potential in The Bronx Urban Environmental Planning

Offers acreage for a range of urban uses Recreation Agriculture Rainwater harvesting Micropower  In the form of generators, windmills, etc.

Mitigate urban environmental problems Storm water runoff Combined sewage overflows  Sources of water pollution Urban heat island effect Air pollution

Economically viable & Little restrictions Load-bearing:  Soil can be very shallow  Low maintenance, drought resistant succulents & low- growing plants Roof slope:  Flat roofs with 5-20 degree slopes work best, but degree slopes still work.

No longer a question of why and how, but when and where? urban areas

lot area vs. roof area

Excluded paved roads for parking

Acreage equivalent to 2 Central Parks

Next steps: Use data satellite imagery to identify the areas with the worst Urban Heat Islands Effects and pollution problems that come from that.
