Series documents the subdividing and partitioning of land within the county. Records include survey notes, correspondence, photographs, satisfaction of agreements, maps of subdivided and partitioned land, and contracts and permits. Information includes subdivision names; lot, street, and alley dimensions; and township, range, and section numbers of land to be subdivided or partitioned.
