Research notes
OK Certified Local Government (CLG) jurisdictions include OKC, Tulsa, Norman, Enid, Guthrie (state's first capital — extensive Victorian district), Bartlesville, Muskogee, Ponca City, Sapulpa, Shawnee, Stillwater, Ardmore, Anadarko, Pawhuska, Tahlequah. Route 66 historic corridor (Tulsa→Sapulpa→Stroud→Chandler→Arcadia→OKC→El Reno→Hydro→Clinton→Elk City→Erick) carries an unusually high density of NRHP-listed motels, stations, and roadside resources — many cities have route-themed corridor overlays separate from the SHPO/CLG framework. Cherokee Heritage Center (Park Hill) and Fort Gibson Historic Site (Muskogee Co.) are state-administered historic resources also inside the Cherokee Reservation under McGirt — coordinate SHPO and tribal historic preservation officer (THPO) consultation. Federal conflict check applies (NHPA §106).
