 And a key city council vote today on a major redevelopment project in St. Petersburg could pave the way to give baseball's Tampa Bay Rays a new ballpark, which would guarantee the team stays for at least 30 years. The $6.5 billion project, supporters say, would transform an 86-acre tract in the city's downtown with plans in the coming years for a black history museum, affordable housing, a hotel, green space, entertainment venues, and office and retail space. There's the promise of thousands of jobs.
