Barring any last-minute snags, the Tampa Port Authority will take ownership of Channelside Bay Plaza soon—and watch for changes to the retail and entertainment complex. Likely among them, according to reports, renovations that are expected to lead to improved leasing activity and maybe even a baseball stadium. Despite an attractive waterfront location, Channelside has struggled with vacancy and disinterest in recent years. That could be about to change. The sale price: $5.75 million.
