(1) Modify the proposed boundaries of the area directly benefited by and to pay for the proposed installations except that no land in the authority which could not be directly benefited by the proposed installation may be included and no land in the authority which could be directly benefited by the proposed installation may be excluded. If it appears that land should be included in the area which was not included within the boundaries designated in the notice of the hearing and that the owners of such land have not appeared at the hearing the board shall adjourn the hearing and give notice to such owners by registered mail, by certified mail with return receipt or by posting and publishing notice in the area to be included in substantially the same manner that notice is given under ORS 450.850 (2). If the notice is given by registered or certified mail, the notice shall be mailed at least 10 days prior to the date fixed for the further hearing. The notice shall contain the date, time and place of the adjourned hearing, a statement that the board proposes to construct sewage treatment plants or trunk or lateral sewers or drains for an area within the authority, a description of the additional area to be included within such area and a statement that all persons interested may appear and be heard.

(2) Determine what installations shall be constructed and the total cost of the construction. The cost of making engineering plans and specifications shall be borne by the area directly benefited by the installation as a part of the construction costs.

(3) Determine the manner in which the property within the area shall bear the cost of the proposed installations. The board may provide, in its sound discretion, that the cost shall be borne by assessments against the property directly benefited, by sewer connection charges, by collection of sewer service charges in the area or, if general obligation bonds are to be issued and sold to finance the construction of the installations, by annual levies of taxes against property in the area, or by any combination of these methods. If all or a part of the cost of the proposed installations are to be borne by assessments against the property directly benefited, the board may, in its sound discretion, levy the assessments in an amount based upon the engineer’s estimate of the cost, or may delay the assessments until the total cost of the installation is determined. Such cost shall be apportioned, so far as practicable, in accordance with the special and peculiar benefit each parcel of land in the area could receive from the installation. Where parcels of land in the area are partially or wholly undeveloped or are devoted to uses which in no way require sewage disposal service, the board may, in its sound discretion, defer assessing, imposing or levying all or any part of the assessments, sewer service charges or taxes against such parcels until the parcels or the undeveloped portions thereof are connected with the installations.

(4) Determine the method of financing the construction of the proposed installations and the amount and type of bonds, if any, to be issued and sold under ORS 450.895 to 450.920 to finance the construction of the proposed installations. [1955 c.614 §34; 1973 c.399 §2; 1977 c.621 §1; 1991 c.249 §37]
