PHOTO PROOF - WHAT MIXED USE DOES TO A DOWNTOWN
The developers who are behind the Orinda Downtown 
  Plan say there needs to be a transit village with hundreds of new condos to 
  give Orinda a nice downtown. 
  
  Look at what has happened in other Bay Area places that have tried to put in 
  transit villages. Usually condos on top of "retail space" -- which 
  ends up being mostly vacant storefronts for lease, with perhaps a nail salon 
  or day spa. No locally-owned shops like hardware stores or other places intended 
  to serve the residents, the kind of retail that truly makes a small town's downtown.
  
  These places are virtually deserted and have no community feel. It is unlikely 
  you will go there and run into your friends and neighbors like you do in downtown 
  Orinda. Meanwhile, the developers have made their money and are long gone, off 
  to their next place to convince townsfolk their downtown needs to be bulldozed 
  and replaced with yet another housing-over-retail "revitalization." 
  
  

  "The Mercer", Walnut Creek, two blocks from BART. Note the "downtown 
  vibrancy" of the nail spa and two "for lease" storefronts.

Where's the "vibrancy"???? Condos over retail in the middle of downtown Napa. Note again the vacant, "for lease" storefronts and the absence of people.
Deserted Hercules Transit Village - another "mixed use" disaster
The following towns have no smart growth and 'vibrant' shopping areas:

Mill Valley

Saratoga

Mill Valley!
and even...

Carmel!!
