Moore Branch Estates is a small estate subdivision in St. Augustine in St. Johns County, outside the historic core in the greener, lower country where the old city grid gives way to larger residential lots. St. Augustine, the county seat, is the oldest continuously occupied European-founded city in the continental United States, anchored by the Matanzas River bayfront, the Castillo de San Marcos and a compact downtown of narrow streets. Away from that core, the county's residential growth spreads south and west along the US 1 corridor, and Moore Branch Estates sits within that broader pattern of single-family estate homes on quieter streets. Public schools are part of the St. Johns County School District. The beaches on Anastasia Island lie east across the Matanzas River, and Jacksonville is roughly an hour north on I-95.
