Okla. Stat. tit. 11, § 11-39-105

within or wholly without or partly without boundary of city levying

assessment - Contracts for improvements.

A. Whenever the boundary of a city is upon or along any street

which at that point lies wholly within, partly within or partly

without or wholly outside of its boundary, but contiguous to the

boundary of the city, the governing body of such city may include

the street in the district, improve that portion of such street and

assess a part of the cost thereof against the abutting property

lying on both sides of such street. Provided, however, if such

street is wholly or partly within the boundary of another city, the

governing body of such other city shall, by resolution, consent to

the improvement and give its consent to assessment of the benefited

property.

B. If, within thirty (30) days after the adoption of the

ordinance levying the assessment by the city creating the district,

the governing body of the city in which the property is situated

does not, by resolution, consent or ratify the assessments, the

governing body of the city creating the district may:

1. Modify the boundary of the district to exclude the property

from the district;

2. Assume the cost of the improvement assessed against the

property lying beyond the boundary of the city; or

3. Nullify the proceedings, including any contract, relating to

the district. Any failure on the part of the governing body of the

other city to ratify the assessments levied by the city creating the

improvement district shall not affect the validity of the

assessments which have been levied against any property lying within

the limits of the city creating the improvement district.

C. The owner, or his designated agent, of any property lying

outside the boundary of the city creating the district and in the

district, including the county and any affected subdivision outside

the city, shall have the same rights granted to owners of property

lying within the boundary of the city creating the district.

D. Whenever a part of the boundary of two or more cities is

upon or along any street or is along the edge of any street and the

governing bodies of the cities determine the necessity for making an

improvement upon any portion of the street, the governing bodies of

the cities may contract, upon such terms as are to them mutually

agreeable, to make the improvement. The contract shall:

1. Authorize one of the cities to create the district pursuant

to the Improvement District Act; and

2. Prescribe the apportionment of the costs, if any, among the

cities and the manner and payment of such cost. The payment of such

costs by the cities party to the contract is lawful whether the

improvement is wholly within, partly within and partly without or

wholly outside its limits.
