Chicago's Chief Environment Officer Interviewed
The city's Chief Environment Officer, Sadhu Johnston, was interviewed by the American Society of Landscape Architects. Some interesting stuff that reminds you of just how hard it is to get anything done in a democracy:
Chicago is now famous for installing millions of square feet of green roof across the city. How critical are these green roofs to the city's program for a sustainable stormwater management?
They play an important role. However, we couldn't give credit to a new development for installing a green roof until we passed our storm water ordinance a couple of years ago. Now, every new development is required to calculate stormwater runoff and figure out how they can keep at least a half-inch of that first rain onsite for utilization and bioswales, green roofs, or other green infrastructure, like permeable pavements. Green roofs can play a significant role in stormwater plans for each site.
You hear that, hippies? You wanna save the earth, you better start brushing up on those 200-page stormwater ordinances.
