The installation of sidewalks required by this chapter shall not be made by the owner until a permit has been obtained from the Service Director. The cost of such permit shall be five cents (5¢) per lineal foot but not less than two dollars ($2.00) for repair of an existing sidewalk, and ten cents (10¢) per lineal foot but not less than five dollars ($5.00) for the installation of a new sidewalk where none has existed before. The Director shall cause the grade of the sidewalk to be established prior to the issuance of such permit, if the grade can be established in relation to a permanent paved roadway, or existing sidewalks on adjoining property. In the event there is no permanent paved roadway or existing sidewalks on adjoining property, the grade shall be established by the Engineer and he shall receive three-fifths of the permit fee but not less than three dollars ($3.00) of the permit fee as and for services in establishing the grade.
