“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 20-40 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.
