Clay County, Florida
Clay County is Jacksonville's southwestern suburb, running from Orange Park and Fleming Island down the St. Johns River to Green Cove Springs and rural Keystone Heights. Growth is residential and commuter-driven, concentrated along the First Coast Expressway, whose completion is opening large tracts of interior timberland — making utility service boundaries and school capacity the practical limits on where rooftops actually go.
