Last summer, we mentioned that University of North Carolina at Chapel Hill professor John D. Kasarda was predicting the rise of "the airport city" -- or, ya know, The Aerotropolis. Chief among those new central business districts is, of course, Dallas-Fort Worth International Airport and GlobeSt.com today fresh news of a mixed-use development shortly to spring up at DFW: something called Southgate Plaza, which'll cost between $250 and $350 million and break ground early next year on 32 acres at the airport. Says it's "the next development move to establish a world-class airport city" at DFW. Which ain't makin' Fort Worth Mayor Mike Moncrief too happy, not at all. --Robert Wilonsky
