Thursday, May 6th, 2010 — About 100 Metro police officers and firefighters went door to door Wednesday trying to account for everyone affected by the historic floods that battered Nashville, while inspectors continued to assess damage that Mayor Karl Dean said would soar well above $1 billion for the city alone. Dean's estimate didn't take into account damage from places elsewhere in the region, which could add hundreds of millions, if not billions, to the total.
