Florida Hospital will donate up to $6 million over the next three years to address the long-festering issue of homelessness in Central Florida, officials will announce Tuesday — a move that is being called historic in its potential to change the lives of individuals living on the streets and families living in cars and cramped motel rooms. Along with more than $4 million already pledged by the city of Orlando and up to $700,000 in cash and rental assistance from Orange County, this stands to be the first serious money spent to do something more than studying the area's homeless problem, which is among the most severe in the nation.
