Sidewalks are optional. Where sidewalks are to be installed or replaced, they shall be constructed in accordance with the following specifications:
(A) Sidewalks shall be provided on each side of all streets where applicable.
(B) (1) Sidewalks constructed within the street right-of-way shall be of portland cement concrete and shall have a minimum width of five feet and a minimum depth of concrete of four inches over three inches of INDOT #53 aggregate stone, except when the sidewalk is designed into a section of a driveway entrance, in which case the minimum depth of concrete shall be six inches over three inches of INDOT #53 aggregate stone.
(2) The surface shall be sloped at a maximum of 1/4 inch per foot toward the street.
(C) Curb ramps shall be installed at all sidewalk-curb intersections in accordance with the Americans with Disabilities Act including the following design criteria:
(1) All ramps shall be a minimum of five feet wide and have a maximum slope no greater than 8.33% (12:1) in the direction of travel and a maximum slope of 2% (50:1) perpendicular to the direction of travel. Where site conditions are such that a five foot wide ramp is not feasible, the ramp shall be as wide as possible with a minimum width of 3 feet, or as wide as possible with a minimum of 32 inches of clear space when passing an obstruction such as a utility pole or other permanent feature not readily convenient for relocation.
(2) All ramps shall have a landing at the upper elevation no less than four feet by four feet, free of obstructions and protrusions, and with a slope no greater than 2% (50:1) in any direction. When site conditions are such that a 2% slope in all directions is not feasible, the slope perpendicular to the primary direction of travel shall be held to a 2% maximum and the slope parallel to the direction of travel shall not exceed 8.33% (12:1).
(3) In extreme cases where the site conditions make a ramp impossible to construct in accordance with items in division (C)(1) and (2), the landing width may be decreased to three feet and the longitudinal slope of the ramp may be increased to 10% (10:1) for a maximum rise of six inches.
(4) All ramps shall be equipped with detectable warning devices in accordance with the most current INDOT standard.
(5) All ramps shall have a broom finished surface with grooves perpendicular to the direction of travel in accordance with the most current INDOT standard.
(6) The algebraic difference in grades between the base of the ramp and gutter shall be no greater than 11%. Where site conditions are such that an 11% difference is not feasible, a two foot wide level strip shall be provided.
(7) Changes in level up to 1/4 inch may be vertical with no edge treatment. Changes in level between 1/4 inch and 1/2 inch shall be beveled with a slope no greater than 1:2. Changes in level greater than 1/2 inch shall be treated as a ramp and shall follow the criteria herein.
(8) Where possible, drainage inlets shall be positioned uphill from curb ramps to prevent puddles in the path of travel. If inlet grates are to be located in walking surfaces, the openings shall be no greater than 1/2 inch wide in the direction of travel. Elongated openings are allowed perpendicular to the direction of travel.
(D) Transverse joints shall be made at intervals of five feet and only with a proper joint cutting tool or metal division plates. One half inch transverse expansion joints shall be placed not more than 40 feet apart and 1/2 inch expansion joints shall be placed along intersecting sidewalks, yard walks, curb walks and street curbing.
(E) Curing of sidewalks shall conform to that of a portland cement concrete pavement as specified in the latest edition of the INDOT standard specifications.
(F) Forms shall be of wood, metal or other approved material and shall extend for the full depth of the concrete. Forms shall be straight, free from warp, and of sufficient strength to resist the pressure of the concrete without springing. Bracing and staking of forms shall be such that the forms remain in both horizontal and vertical alignment until their removal.
(G) The surface shall be finished with a wooden float with broom finish. No plastering of the surface shall be permitted. All outside edges of the slab and all joints shall be edged with 1/4 inch radius edging tool.
