Flagler Ain't Flagging

Okay, so Flagler County, on Florida's Atlantic Coast south of St. Augustine, had the highest rate of growth in the number of housing units of any county in the nation for the second year in a row, the U.S. Census Bureau estimates. I'm not sure how significant this is, except that it might be the last secret swatch of sand in the Sunshine State. The trouble with counts by county is that Flagler shoots to the top of the list with only 5,000 new housing units -- a nearly 15 percent jump over 2005. Also on the list: Maricopa County, the Arizona sprawl that includes Phoenix, with 52,000 homes added.
