Where Will They Park Their Zeppelins?

In 1976 LHENA got together with some architects and planners, and collaborated with them on something called the Wedge Design Framework Plan. This proposal includes one-way conversions for all north-south streets; it would have turned Aldrich, Colfax, and Emerson Avenues into cul-de-sacs at 29th street. It's also got diagonal parking (LHENA later disapproved this) and a rec center for cats (I don't know what became of this). Bonus points if you can find the zeppelin.
