can't offer any examples of how to do it, but not too far from you, my hometown, Muskegon, Michigan offers a great example of what
not to do.
I don't want to hijack your thread, if this should be a separate thread I'll defer to others...
In the 70's, downtown properties were assembled and collectively enclosed into a mall. Of course, they had to take it a step further, enclosing it, and knocking down several buildings so that it could be surrounded by acres of parking, just like the burbs. And, of course, any building with character that had the misfortune of being within "the mall" that wasn't demolished for peripheral parking was quickly dolled up to look like a "storefront" within a mall (i.e., stripped of any character).
It struggled through lots of changeover in tenants, and some good did come of it in that there was some adjacent development as a result (improvements to an already existing sports arena, hotel development, some restaurants).
But the mall couldn't compete with the Bed Bath and Beyond type of development taking form in the outlying burbs, and it's anchor stores, which were already struggling, were all to eager to move out to the former blueberry fields in what is now strip mall heaven.
Those businesses which did move downtown to be near the mall are now lying next to more than ample parking (empty lots), and the stores have largely been demolished, replaced by piles of sand. Now Muskegon stands planning it's next move, trying to find out how to replace the downtown which was systematically demolished. Not a pretty sight. Anyone going north into Michigan on US 31 is encouraged to stop and take a look at how bad things can become.
