Long Bay Acres is a small residential subdivision in Middleburg, the unincorporated community that anchors southwest Clay County along Black Creek. Middleburg grew up around the creek and Blanding Boulevard, and its neighborhoods mix older rural roads with newer subdivisions set among pine flatwoods and oak hammocks. Long Bay Acres follows that pattern, with homes on comparatively generous lots along quiet interior streets, away from the commercial strip. There is no dense town center here; schools, shops and services cluster along Blanding Boulevard and Branan Field Road, and Black Creek itself offers boat ramps and fishing a short drive away. Public schools belong to Clay County District Schools. Commuters reach Orange Park and Jacksonville by Blanding Boulevard, which runs northeast out of Middleburg toward the St. Johns River crossings.
