Witt Home Ranch, Inc. owned a large parcel of undeveloped land in Sonoma County. In 1915, the county board of supervisors approved a map that subdivided the parcel into 25 lots. The map was recorded, but was never implemented through sale of the individual lots. Rather, the lots remained united as a single parcel with a single owner.

In 2005, Ranch applied to the county for certification of the individual lots on the basis of the 1915 map.
