Southridge is a residential subdivision in Jacksonville, in Duval County in Northeast Florida, within the city's sprawling pattern of neighborhoods on both sides of the St. Johns River. Its streets belong to Jacksonville's established suburban landscape, where single subdivisions sit alongside older communities and newer development as the city has grown outward over many decades. The housing is residential in character, set in that broader Jacksonville context of tree-lined local roads, nearby shopping corridors and schools spread across the consolidated city-county. Public schools are part of Duval County Public Schools. The river, Downtown Jacksonville and the beaches at the county's eastern edge are all part of the same Jacksonville setting that surrounds the neighborhood.
