Okla. Stat. tit. 69, § 69-1321

(a) In the event condemnation proceedings have been instituted

in connection with the construction of such limited access facility

and interim certificates have been issued by the governing body or

board of county commissioners in accordance with this article, at

such time as all the proceedings become final and it may thus be

determined with definiteness the exact amount of money so advanced

by the contractor for that purpose, the governing body or the board

of county commissioners shall, by resolution, determine the exact

sum, together with accrued interest, due to the owners and holders

of the outstanding certificates, and shall appoint a time for

holding a session to apportion such total sum, and to hear

objections thereto.

(b) Notice of such hearing shall be published by the city or

county clerk in five consecutive issues of a daily newspaper or in

two consecutive issues of a weekly newspaper published in the county

and in general circulation in the city or county. The time fixed

for hearing shall not be less than five (5) days nor more than

fifteen (15) days from the date of the last publication.

(c) At the time and place specified in such notice the governing

body or the board of county commissioners shall apportion the amount

among the tracts, pieces and parcels of land in exact ratio and pro

rata to the apportionments theretofore made in accordance with this

article for the cost of construction; and objections and complaints

shall be limited to whether or not such apportionments are, or are

not, in strict ratio or in identical proportions to such previous

assessment.

(d) The apportionments shall be levied by ordinance or

resolution, which shall provide that the owners of the property so

assessed shall have the privilege of paying the amounts of their

respective assessments without interest at any time within thirty

(30) days from the date of the first publication of the ordinance or

resolution.
