Two things show me how flawed the adopted criteria is: The problem with rebuilding the garage that just burned down, requiring rear parking, and the idiocy of thinking that people (customers) will park in back, walk around through an alley, and go in the front door of a business. I just had lunch at the Riverside Family Restaurant where many old-timers go, and I can tell you that the people that operate that restaurant think the new zoning criteria as regards setback and parking are misguided and would kill their business. The existing buffer of mostly residential is the best protection we could hope for for the adjacent homes. This costly zoning process - for all three districts - has been a fiasco. What the "planners" amongst us seem to want is an unbroken wall of the kind of junk that has been built in Burr Ridge Town Center or whatever they call it - and if you look closely you will see that most of that stuff is empty - above and below. Harlem is not beautiful, but it is real. No one will ever say that about Burr Ridge.
BTW - there are a lot of those big barns out along County Line that appear empty - I'll bet that will be foreclosure heaven in six months to a year.
