903.01 CONSTRUCTION AND REPAIR OF SIDEWALKS. 
   (a)    All sidewalks hereafter constructed in any of the streets or highways of the City shall be of concrete. Such sidewalks shall be of the uniform width of four feet, unless a different width shall be provided in any resolution of Council hereafter ordering sidewalks to be constructed in any one or more streets, or unless a different width shall be ordered by the Director of Public Service in order to conform to existing sidewalks.
   (b)    Such sidewalks shall be constructed in accordance with the plans and specifications for sidewalks heretofore adopted by Council, and now on file in the office of the Director of Public Service, which shall at all times be so kept on file and open to public examination. They shall be constructed with a cross-slope of three-eighths of an inch per foot, and shall be placed with the inside edge, being the edge next to the lot line, one foot from the lot line, and at an elevation above the curb grade of three- eighths inch for each foot that the sidewalk is distant from the curb, plus one inch rise at the curb. However, in order to conform to existing sidewalks or to meet special conditions, Council may in its resolution ordering the construction of sidewalks, or the Director of Public Service by special order, may direct a different location with reference to lot lines, or a different elevation for any sidewalk, which resolution or special order shall prevail.
