Okla. Stat. tit. 19, § 19-881: Computation and apportionment of cost - Assessment -

Special assessment bonds.

As soon as any subdistrict sewer line or lines shall have been

completed the engineer having charge of the work shall compute the

whole cost thereof which shall also include the cost of advertising,

appraising, engineering and such other expense necessary or

essential or incident to the completion of such work and shall

apportion the same against all of the lots or pieces of ground in

such district in proportion to the area of the whole subdistrict,

exclusive of the public highways, and such officer shall report the

same to the board of directors and the said board of directors shall

thereupon assess a special tax against each lot or piece of ground

within said subdistrict, which assessment so made shall be published

in some newspaper of the county of general circulation within said

district for two consecutive weeks, during which time said

assessments without interest may be paid to the clerk. If at the

expiration of such time the amount named in such assessment together

with the cost of publication, shall not be paid, then said board of

directors shall cause special assessment bonds to be issued against

such lots or pieces of ground in said subdistrict, which special

assessment bond shall recite the date and fact of the making of such

assessment, the amount of the assessment, the description of the

property against which the same is made, and that the same will be

charged or levied against said property in five equal annual

installments with interest thereon at the rate of not to exceed six

percent (6%) per annum, each of said installments to become due and

payable on the 1st day of September in each year which shall become

delinquent if not paid before October 1st in said year and said

bonds shall be signed by the director of the board of directors and

countersigned by the clerk and delivered to the contractor;

provided, that the other expenses incurred by said district in

addition to the contract price of the work shall be paid to the

district by the contractor in cash and the aggregate amount of such

bonds delivered to the contractor shall not exceed his contract

price, and the amount of the expenses paid in cash to the district

by the contractor; provided, further, that in no case shall said

district be empowered to pay any such special bonds from any of the

funds of said district, nor shall it be liable for the amount of

such bonds, until the amount of said assessment shall be collected

from the property described in said bonds. Said bonds shall bear

four coupons evidencing respectively the first, second, third and

fourth installments due thereon; together with interest on the same

and interest on the unmatured installment or installments. The bond
