On September 9th, New Orleans unveiled an innovative proposal for flood management: the New Orleans Greater Water Plan. Designed by Dutch engineers and led by chief architect and planner David Waggonner of locally-based firm Waggonner & Ball Architects, the plan seeks to mitigate the damages caused during heavy rainfalls. The concept is simple: keeping water in pumps and canals instead of draining and pumping it out. The idea is to retain the water in order to increase the city’s groundwater, thereby slowing down the subsidence of soft land as it dries and shrinks.
Nothing says “sustainable architecture quite like a green roof. AN has rounded up eight of the latest green roof and subsurface components that the pros use to seal out, drain, or retail water, like the Green Roof Blocks system (above) by Green Roof Blocks.
The Green Roof Block system is a completely self-contained module made from high-grade anodized aluminum. It can be pre-planted with a growth medium that the company guarantees will never break down. Built-in drainage and convenient handles make the units easy to install.
