The city council shall hear, consider, and pass upon the protests against the proposed improvement at the time appointed, or at any time to which the hearings may be adjourned, and its decision on all matters of protest shall be final and conclusive. If those protests are sustained, the proceedings shall be abandoned but may be renewed at any time. If those protests are denied or if no protests are filed the proposed assessment as the same shall have been modified or corrected shall be confirmed, and the city council shall thereupon acquire jurisdiction to proceed with the improvement and may by resolution order the proposed improvement to be made.

If there is a majority protest by the landowners in any zone to the improvement in that zone, or if the officer or person designated reports that it is practical to subdivide a zone and a majority of the landowners in that subdivided zone protest the improvement in that subdivided zone, the city council shall strike that zone or subdivided zone from the proceedings and correct the proposed assessment accordingly, unless that body, by a four-fifths affirmative vote of all its members finds that the public interest and convenience require that street lights in that zone or subdivided zone be improved. The determination of the city council shall be final and conclusive.

If a zone or subdivided zone is struck from the proceedings, the city council may proceed the same as though that zone or subdivided zone was not a part of the original proceedings.
