Okla. Stat. tit. 19, § 19-868.15: Procedure for adoption of zoning regulations

Prior to the adoption of any zoning regulations, the board of

county commissioners shall request the county planning commission to

recommend the boundaries of the various districts and appropriate

regulations to be enforced therein. The county planning commission

shall make a preliminary report of its recommendations for such

zoning regulations and shall hold a public hearing thereon for each

township to be affected by the proposed regulations. Such hearings

may be adjourned from time to time. Within ninety (90) days after

the final adjournment of such hearings the county planning

commission shall make its final report together with its proposed

zoning regulations and a summary of the results of the public

hearings to the board of county commissioners. The board of county

commissioners may then adopt the proposed regulation or refer it

back to the county planning commission for further consideration.

If a written protest against the proposed zoning of any land lying

within one and one-half (1 1/2) miles of the limits of any

municipality having a zoning ordinance is received from the

governing body thereof, the board of county commissioners shall not

adopt the proposed zoning regulations of such land except by a

record vote of all members and after a statement of the reasons for

such action shall be spread upon its minutes or records.
