Has Chicago been doing that? Did they get a FAR bonus for puting in storm water retention?

Actually, the burbs have been pathetically slow to adopt new techniques of storm water retention. The metropolitan water reclaimation district (MWRD, governs Lake, Cook(but not the city) and Dupage, i think) still does not recognize a green roof as a means to reduce the rate and volume of stormwater. The city has been
much, much better at allowing alternative means of stormwater treatment. The whole stormwater retention for FAR bonuses doesn't really work for the suburbs since they don't really have control over their stormwater management. Besides, i might argue that denser projects should have relaxed stormwater requirements because they will cause less run off than a sprawling, glory-to-walmart project.
There is nothing in the chicago zoning ordinance (to my knowledge) that gives FAR bonuses based on storm water retention. Being able to retain water on site is more of a bargaining chip when asking for more density as part of a variance or special use. Besides, i read that all new projects in the city, over 30,000 sq.ft. will be required to retain 1" stormwater on site beginning Jan 1.
Also, SamInTheLoop, check out the OMP thread, we were talking about what is going MPW in there a bit.
