Okla. Stat. tit. 11, § 11-36-203: Preliminary plans and costs of improvement - Governing

body action.

Whenever the municipal governing body deems it necessary to

grade, pave, construct, macadamize, chat or gravel, curb, gutter,

drain or otherwise improve any street, alley, avenue, lane or any

part thereof which shall have been heretofore paved, within the

limits of the municipality, it shall direct, by resolution, the

engineer to prepare preliminary plans and an estimate of cost. The

resolution shall require the engineer to prepare and submit to the

municipal clerk the following:

1. Preliminary plans, showing a typical section of the

contemplated improvement, the type or types of material, and

approximate thicknesses and widths;

2. Assessment plat, showing the area to be assessed; and

3. Preliminary estimate of the total cost of the improvement.

The cost estimate may be in a lump sum or by unit prices, as the

engineer may deem most desirable, for the improvement complete in

place. The estimate shall also include the cost of advertising,

appraising, engineering, and such other expense as in the judgment

of the engineer is necessary or essential to the completion of the

work of improvement and the payment of the cost thereof. The

engineering fees shall not exceed five percent (5%) of the contract

price of the improvement. If the resolution provides for one or

more types of construction, the engineer shall separately estimate

the cost of each type of construction. If more than one street,

avenue, alley, lane, public place, or part thereof is included in

such resolution, separate estimates as to each shall be made.
