(A)   Before proceeding with the repair, construction, or erection of a sidewalk which serves as a roof over vaults or areas between the curb and building line, the owner or contractor, or his agent, shall obtain a permit from the City Council as provided. If other construction, alteration, or repairs requiring a building permit are included in the same contract then one building permit may include the entire job. Such sidewalks shall be so constructed that they will safely bear in addition to their own weight a live load uniformly distributed of 250 pounds per square foot of surface. No such sidewalk construction, repair, or demolition shall be begun or continued without sufficient barriers, railings, signs, temporary walkways, lights, and other safety measures as required by this chapter, adequate to protect the public from injury. It shall be unlawful to insert or cause to be inserted in any sidewalk any prism glass, panel containing such glass, open grill work, or any material which becomes more slippery when wet than the surrounding concrete walk.
   (B)   Whenever a new residential or commercial building is proposed to be constructed within the corporate limits of the city, or wherever an existing building is moved to or relocated on a new lot or different site, the builder or contractor, or owner of the land upon which the new or relocated building is to be constructed or relocated shall also provide and construct at his expense a sidewalk across the land along and parallel with the street lines at a distance of one foot away from and outside the block lines.
   (C)   Such sidewalks shall be constructed in all respects in accordance with applicable specifications and requirements as set out in Lockport's Development regulations, which include but are not limited to the following:
      (1)   Sidewalks shall be constructed of Portland cement concrete at a width of five feet.
      (2)   Sidewalks shall have a minimum thickness of five inches, except the thickness shall be six inches where passing over recently buried public utility lines.
      (3)   Sidewalks that are replacing existing sidewalks can be placed upon a natural earth subgrade. Where fill is necessary, the fill must be of a CA6 aggregate base. New sidewalks shall be placed on a five-inch minimum thickness granular base.
      (4)   Reinforced bars shall be embedded in the concrete 1 1/2 inches from the bottom in a longitudinal direction over all new water or sewer services or other utilities recently buried beneath the sidewalk. Three 3/4-inch diameter bars, each with a minimum length of ten feet, shall be installed over each utility trench. The bars shall be equally spaced across the width of the sidewalk.
      (5)   Expansion joint 1/2-inch thick shall be placed between sidewalks and all structures such as light standards, utility poles, traffic light standards and traffic poles which extend through sidewalks.
      (6)   Expansion joints 3/4-inch thick shall be placed at maximum intervals of 50 feet in sidewalks and where specified by the City Engineer. Expansion joints shall also be placed where the sidewalk abuts existing sidewalks, between driveway pavement and sidewalks, and between sidewalks and curbs where the sidewalk abuts a curb.
   (D)   All supporting form work shall be constructed of sufficient strength to safely bear all the load of the sidewalk material and shall remain in place for a period of time equal to 24-hours for each foot of clear span.
