Okla. Stat. tit. 11, § 11-47-117: Improvements in unapproved streets

The municipality shall not accept, lay out, open, improve,

grade, pave, curb, or light any street, or lay or authorize water

mains or sewers or utility connections to be laid in any street,

within any portion of territory for which the commission shall have

adopted a major street plan, unless the street:

1. Shall have been accepted or opened as or shall otherwise

have received the legal status of a public street prior to the

adoption of the street plan; or

2. Corresponds with a street shown on the official master plan

or with a street on a subdivision plat approved by the commission or

with a street on a street plat made by and adopted by the

commission.

However, the council may accept any street not shown on or not

corresponding with a street on the official master plan or on an

approved subdivision plat or an approved street plat, provided the

ordinance or other measure accepting such street be first submitted

to the city planning commission for its approval, and, if approved

by the commission, be enacted or passed by not less than a majority

of all the members of the council. If the ordinance or other

measure accepting such street is disapproved by the commission, the

ordinance or measure may be enacted or passed by not less than two-

thirds of all the members of the council. A street approved by the

commission upon submission by council, or a street accepted by two-

thirds vote after disapproval by the commission, shall thereupon

have the status of an approved street as fully as though it had been

originally shown on the official master plan or on a subdivision

plat approved by the commission or had been originally platted by

the commission.
