Thematic, archaeological, and architectural/historic resource surveys are great resources for the history of particular buildings, particular areas, and for local history, in general.
The 2012 Historic Resources Survey of the Cliff Dweller Houses on Reservoir Hill examines 17 single-family residences that sit along the spine of Reservoir Hill. The pre-1933 houses are unique among other Tulsa homes during that time period because of their Spanish Colonial/Mission Revival and Pueblo Revival architectural styles. The survey states:
"At a time when most neighborhoods were defined by houses with Minimal Traditional, Tudor, or Craftsman features, the Spanish Colonial/Mission Revival and Pueblo Revival houses that dominate Oak Cliff set it apart. Within the survey area are houses of other styles that have commonalities with the Spanish Colonial/Mission Revival and Pueblo Revival buildings -- all were constructed within a very short period of time and they share a setting that was designed to take full advantage of the Reservoir Hill site. Oak Cliff was platted by a group of investors that included brothers Cass and John Mayo. The Mayo brothers are well-known today for the four buildings they constructed in downtown Tulsa, all of which are listed on the National Register."
Originally allotted to Cherokee R. B. Lloyd, Oak Cliff was platted in 1923 and advertised in the Tulsa World as "Tulsa's Sub-Division De Luxe."
The report includes a visual representation of Tulsa's expansion during particular time periods (pictured left) and is available online from the OKlahoma Historical Society.
