In case three or more adjacent properties are posted with notice to construct a sidewalk, curb, or both as set forth in Section 17.28.030, they may petition for such construction as a local improvement. Otherwise, it is the duty of the owners of properties posted with such notice to construct the sidewalk, curb, or both. Before constructing the sidewalk, curb, or both, the owner, designated agent or the occupant of the property intending to construct the sidewalk, curb, or both must obtain from the City Administrator a permit for the construction that will prescribe the kind of sidewalk, curb, or both to be constructed, the material to be used and the width of the sidewalk, curb, or both. After notice to construct sidewalk, curb, or both has been posted, the owner, agent or occupant must construct the sidewalk, curb, or both within 30 days from the date of posting or within that time must show cause, if any, by a written remonstrance addressed to the City Council stating why the sidewalk, curb, or both should not be constructed. The Council will grant a hearing to the remonstrator at a regular meeting as soon thereafter as the same can be filed on regular Council Calendar. The Council will then determine whether or not the sidewalk or curb, or both, must be constructed.  If the remonstrator is not present at the time of such determination by the Council, the revenue service and program of the City Administrator will notify the remonstrator of the Council’s determination by mail sent to the address given upon the written remonstrance. Failure of the revenue service and program of the City Administrator to send the notice, or failure of the remonstrator to receive it, or any other mistake of the notice will not render void or ineffective the lien to be imposed upon the property in the event of City construction. If the Council determines that the sidewalk, curb, or both must be constructed, the owner or designated agent or the occupant must within 10 days afterwards begin the construction of the sidewalk, curb, or both and diligently prosecute the work to final completion.
