Before any street or alley is ordered paved, the grade and property lines thereof shall be fixed and approved by Council, and the profile thereof recorded.
In case persons desire to have any street or alley paved upon their petition, if no grade and property lines have been fixed and approved as aforesaid, the persons owning a majority of the frontage shall file their petition in writing requesting that the grade and property lines be surveyed and determined by the Town Engineer and approved by Council.
After approval of the grade and property lines as aforesaid, persons owning a majority of the frontage may petition Council to order any street or alley graded, curbed or paved as provided in this article, which petition shall be accompanied by the plan and profile showing the approved grade and property lines and shall contain suitable provisions waiving all damages for the improvement of the street in accordance with the established grade and property lines thereof as shown upon such plan and profile. Petitions for the improvement of streets or alleys may also contain offers of payment in cash or annual installments of ten years or less; and Council may require that the estimated cost of improvement of any street or alley shall be deposited before the work is commenced. All petitions and profiles attached thereto shall be recorded before the work authorized by Council is begun.
Inasmuch as the proceeds of the sale of bonds may be used legally only for paving purposes and not for alleged damages, it is provided that where a street or alley has been improved according to the plan and profile approved by Council before the work is begun, no claim for damages will be considered by Council unless substantial changes in the grade have caused material injury to the abutting property or until it has been established by a court of competent jurisdiction in the manner provided by law.
