Williamson County south of Nashville is the wealthiest county in Tennessee and one of the fastest growing in the Southeast. The Harpeth River creates flooding risk through Franklin and surrounding communities. A major EF3 tornado struck the county in March 2020 during the same outbreak that devastated parts of Nashville. The county hosts major healthcare and technology company campuses as Nashville's premier southern suburb.
