Improvement under this chapter shall be ordered, where such improvement is to be paid for in whole or in part, by local assessment where the estimated cost of such improvement, if such cost is all to be assessed to the property in the district, or that portion of the estimated cost to be assessed, if a portion only of the total cost is to be assessed, when added to all other outstanding and unpaid local improvement assessments against the property included in the district, excluding penalties and interest, shall exceed the actual value of the real property, exclusive of improvements thereon, within the district according to the valuation last placed upon it for purposes of general taxation; provided, that when a local improvement is petitioned for by the owners of 75 percent of the lineal frontage upon the improvement and 75 percent of the area of the property within the district, and the petition requests that such limitation be exceeded, the city council or other legislative body may proceed with the improvement in the usual manner if the property owners so petitioning, or any of them, or any person in their behalf, shall deposit with the city a sum in cash equal to the amount that the estimated cost of the improvement shall exceed the limitation herein before provided in this chapter. The sum so provided and deposited shall be applied and credited on the assessment roll for the district, by the treasurer upon his receipt of the roll for collection; provided further, that the city council or other legislative body of the city may, by unanimous vote, order the construction of sanitary sewers and necessary accessories for the disposal of sewage, or for the construction of any sanitary fill in the manner now provided for by law, where in its judgment the same are necessary for public health, and may assess a part or a whole of the costs thereof to the property benefitted, without regard to the foregoing limitation; provided further, that no assessment for diking, draining, sanitary fill or sanitary sewers or water mains shall be included in any computation of outstanding assessments under the provisions of this chapter.
