The City Council may order and cause to be constructed, under the supervision of the Street Commissioner, those street, avenue and alley crossings as the City Council deems necessary. When a petition for the construction of any such crossings is filed by an interested resident in the office of the City Clerk-Treasurer, the Clerk-Treasurer shall refer the application to the Street Commissioner, who shall investigate and make a recommendation to the City Council. Action by the City Council on the application, whether the application is approved or rejected, shall be considered final.
