When a permit is granted for construction of a sidewalk, the City Engineer shall make or cause to be made a survey and set stakes indicating the location, grade and elevation of the sidewalk. It shall be unlawful for any person to construct or cause to be constructed the sidewalk at any other location, grade or elevation than so designated. In determining the location, grade and elevation, the Engineer shall conform to such specifications, rules or regulations as the City Council may prescribe. The survey (one) shall be made and stakes set by the Engineer within ten days after the application being filed for the sidewalk permit. The fees of the Engineer shall be paid by the City, but if the person obtaining the permit and survey fails or neglects to construct the curbing or sidewalk within 60 days thereafter or requests a second survey, the fee shall be assessed to the permit obtaining the permit and the applicant shall be liable to the City for the fee paid for the survey.
