Okla. Stat. tit. 73 § 96
The Director of the Office of Management and Enterprise Services is hereby authorized to regulate parking of vehicles on the streets in the vicinity of the State Capitol, the state office building, the State Historical Building, the State Armory, and other public buildings on the State Capitol grounds. Copies of such regulations, including amendments thereto, shall be filed in the Office of the Secretary of State and in the office of the city clerk of the City of Oklahoma City, and copies thereof shall be transmitted to each officer, board or commission having offices in said buildings. A reasonable amount of parking space shall be reserved on the streets immediately adjacent to each of said buildings for citizens, not officers or employees of the state, having business to transact in such buildings. Parking space on the streets and on the public grounds may also be reserved for officers and employees. Such regulations may provide for diagonal or parallel parking of vehicles, the time limit for parking in spaces reserved, when such regulations shall be applicable, the placing of appropriate signs and other markings as to the availability of parking space, the issuance of appropriate stickers identifying vehicles, reservation of space for bus stops, and such other reasonable regulations as are deemed necessary to an orderly system to prevent congestion of traffic and the abuse of parking privileges on said streets. The Attorney General shall assist the Director of the Office of Management and Enterprise Services in the preparation of said regulations. Such regulations shall be enforced by the Highway Patrol Division of the Department of Public Safety and by the police of the City of Oklahoma City or other peace officers. The authority of the City of Oklahoma City to regulate parking on the streets in the vicinity of the above referred to buildings is hereby withdrawn, and the Director of the Office of Management and Enterprise Services and the city manager of the City of Oklahoma City shall cooperate to the extent necessary in specifically defining the boundary or territorial limits of the respective jurisdictions in respect to the subject matter of this section and Section 97 of this title.
