All sidewalks shall conform to the following alignment and grade requirements:
(a) Alignment. Sidewalks constructed within the street right-of-way shall be located in a manner such that the edge of the sidewalk parallel to and farthest from the roadway shall be one foot from the right-of-way line or at any other location as approved by the Township Engineer and as permitted by the Macomb County Road Commission or the Michigan Department of Transportation. In any such case where sidewalks have been constructed prior to the effective date of this chapter, any additional sidewalk to be constructed hereafter may be in alignment with the existing sidewalk to the roadway of the nearest intersecting street. It is the duty of the contractor or other person installing such sidewalk to accurately survey or otherwise determine the location of the right-of-way line prior to installing such sidewalk.
(b) Enclosed Storm Drainage Necessary for Construction of Sidewalks in Streets Having a Right-of-Way of Sixty Feet or Less. Where streets have a right-of- way of sixty feet or less, enclosed storm drainage shall be installed parallel to any required sidewalk utilizing permanent corrugated tubing or pipe placed in a grade and manner for proper street drainage with materials and design subject to approval by the Macomb County Road Commission and the Charter Township of Clinton. Catch basins may be required at no greater than 200 feet intervals and final grade shall be subject to approval by the Township Engineer.
(c) Grade of Sidewalks Where Right-of-Way is Sixty Feet or Less. Where the adjacent road has a curb the sidewalk shall be constructed to a grade established at a slope of three-eighths of an inch per foot above the curb as measured from the curb to the nearest edge of the sidewalk to the curb. When the road does not have a curb, the sidewalk shall be constructed in a manner such that the edge of the sidewalk farthest from the roadbed shall be established at an elevation midway between the elevation of the center line of the street and the elevation of the adjoining houses, subject to a minimum elevation of six inches below the outside grade of adjacent houses and not more than an elevation of nine inches above the center line of the street or as approved by the Township Building Official.
(d) Grade of Sidewalks on Streets With Right-of-Way Greater Than Sixty Feet. The grade of sidewalks shall be established by the Township Engineer in a manner consistent with grade specifications set forth above altered as necessary for existing conditions and the width of such right-of-way.
