§ 91.10 SIDEWALK AND DRIVEWAY APPROACH SPECIFICATIONS.
   (A)   All sidewalks and driveway approaches hereafter constructed within the city shall be constructed of concrete cement compounded of portland cement, clean sand, clean gravel, and water in sufficient quantities to achieve a 28-day compressive strength of at least 3,000 pounds per square inch when tested in accordance with applicable standards of the American Society for Testing Materials. No white sand shall be used in the mix. Concrete shall be poured monolithically and shall be a minimum six sack mix.
   (B)   All sidewalks hereafter constructed or repaired shall be of the following minimum width, exclusive of any curb:
      (1)   Within a commercial zone as defined by the zoning ordinance of this city, or adjacent to any property owned, used, or to be used for school or public education purposes, the minimum width shall be eight feet, or shall conform to the existing width, if it is wider; and
      (2)   Elsewhere: five feet, except curb line walks shall be five feet inclusive of curb surface, or conform to existing width.
   (C)   All sidewalks shall be four inches minimum thickness and six inches minimum thickness across driveways and alley approaches.
   (D)   Sidewalks shall have a fall of 0.025 inches per foot from the property line toward the curb, and shall be so laid that the street side of the walk shall be at an elevation equal to that of the curb of the street, unless the City Manager shall otherwise authorize.
      (1)   Expansion joints one-half inch wide shall be placed at maximum intervals of 30 feet and shall be placed wherever a new walk joins an existing walk, driveway, or other solid object, and at points of direction change.
      (2)   Sidewalks shall be divided into square blocks of no greater dimension than seven foot, by joints running across the walk at right angles to their length. Each joint shall be plainly marked with a deep cutter two inches in width. The edges of all blocks shall be smoothly marked with a three-inch edger and be free from broom marks. All sidewalks shall receive a broom finish.
      (3)   Forms shall be free from warping or breaks and be of sufficient strength, and properly anchored and braced, to ensure holding of true lines and grades.
   (E)   (1)   Where the earth is in an undisturbed condition, no sidewalk bed other than the earth needs to be used.
      (2)   Where the earth has been disturbed, either through leveling or clearing, then a sidewalk bed of sand or small gravel not less than three inches in depth shall be placed before the sidewalk cement is poured.
   (F)   All sidewalks shall be laid adjacent to the street curb, except:
      (1)   Where an existing portion of sidewalk already exists within the block on or near the property line, all sidewalks upon that side of the street and within the block where the existing property line sidewalk exists shall be constructed adjacent to the property line; and/or
      (2)   Where the City Council by resolution shall provide otherwise.
   (G)   The City Manager may authorize the installation of a meandering sidewalk for aesthetic purposes provided the walk does not substantially inconvenience the general public nor create an apparent traffic or pedestrian hazard.
   (H)   (1)   All cuts or demolition made to existing city sidewalks, or to an adjoining city street, shall be made by concrete or pavement saw cuts and appropriate saw cutting equipment at locations approved by the City Manager.
      (2)   Any cuts made to a city curb or city street shall be repaired and repaved in compliance with city street specifications, at the property owner’s expense.
