Okla. Stat. tit. 19, § 19-288.1: Duty to file and index plats

A. Plats or subdivision plats filed in the county clerk's

office shall be indexed and filed, and one copy placed in bound

volumes or booklets, so that all plats or subdivisions are compiled

and indexed accordingly.

B. Plats or subdivision plats of property in unincorporated

areas with roads of public designation shall not be filed in the

county clerk’s office until such plat or subdivision plat goes

before the board of county commissioners and the board determines

that the dedicated public roads are designed to meet the

requirements of Section 601.1 of Title 69 of the Oklahoma Statutes.

The county commissioners shall have adequate assurance by the

developer that the roads will be built according to requirements.

Those assurances shall include, but not be limited to, letters of

credit, bonds, letters of escrow, or other items approved by the

board of county commissioners. The board shall sign the plat and

note on the plat that “Roads will be maintained by the county” or

“Roads will not be maintained by the county”, provided however, that

the county may agree to maintain the roads at some future date.
