Walks con- structed in front of and siding business or industrially zoned property shall be six (6) feet in width and five (5) inches in thickness. Location of walks shall be one (1) foot streetward from the right-of-way line, unless otherwise authorized by the President and Board of Trustees of the Village of Mount Prospect where the abutting property owner would suffer undue hardship and the installation of such other type sidewalk will not be injurious to the public safety. The standard grade for sidewalk shall be five (5) inches above the curb in streets where curb is existing. Where conditions require, this standard may be modified as directed by the Village Inspector. Where no curb exists, the grade shall be established by the Village. No sidewalk shall be installed when the temperature is 450 or lower or when the United States Weather Bureau forecasts a temperature of less than L~oo within 48 hours after pouring concrete. ~ "'i - 2 - All work and materials used shall be inspected by the Village Inspector and the finished sidewalk shall be sub- ject to inspection and acceptance by the Village prior to authorizing payment to the Contractor. Concrete shall be plant or transit mixed and shall contain not less than five bags of cement per cubic yard of concrete. Cement, sand, and course aggregate shall be mixed in the proportion of 1:3:5. Water content shall be sufficient only to permit proper placing and finishing. All concrete used shall be subject to satisfactory inspec- tion by the Village Inspector. During excavation, all unsuitable material such as black dirt, broken concrete, spoil or any other material deemed unsatisfactory by the Inspector shall be removed from the sidewalk area and a satisfactory subgrade established.. Fill under sidewalks shall consist of sand or gravel, satisfactory to the Inspector. The subgrade shall be tamped or rolled until trlOroughly compacted; shall be constructed true to line, grade and cross section for the bottom of the sidewalk or sidewalk apron; and shall be prepared sufficiently wide to accommo- date the forms. Embankments prepared for walk construction shall be not less than six (6) inches wider on each side than the width of the walk to be installed. Side forms shall be lumber with a nominal thickness of two (2) inches, or of steel of equal rigidity. They shall be held securely in place by stakes or braces, with the top edges true to line and grade. The forms for street sidewalks shall be so set that the slab will have a fall of one (1) inch vertical to four (4) feet horizontal, from the edge nearest the property line toward the edge farthest from the property line. Forms for the sidewalk aprons shall be so set that the slab will have a uniform fall between the sidewalk proper and the curb grade. Forms shall be of a depth equivalent to or greater than the thickness of the walk. The sub-grade or sub-base shall be adequately moistened just before the concrete is placed. The concrete shall be placed in successive batches for the entire width of the slab, tamped until all voids are removed and free mortar appears on the surface, thoroughly spaded along the edges, struck off to the true grade, and finished to a true and even surface with suitable trowels and floats. The surface shall be divided by grooves constructed at right angles to the centerline of the sidewalk. These grooves shall extend to one-quarter (1/4) the depth of the sidewalk; shall be not less than 1/8 inch or more than 1/4 inch in width; and shall have the edge rounded 1/4 inch. No slab shall be longer than six (6) feet or less than four (4) feet unless otherwise approved by the Inspector. The side edges of the walk shall also be edged with an edging tool, having a ... - 3 - one-fourth (1/4) inch radius. The finished sidewalk shall be finally dragged across its width with a brush or the surface otherwise roughened by approved methods to give a non-skid finish. Expansion joints one-half (1/2) inch thick shall be placed at intervals of about fifty (50) feet in the side- walks at locations designated by the Village Engineer. Expansion joints one-half (1/2) inch thick shall be provided between the sidewalk and all structures, such as light standards, traffic light standards, traffic poles, etc., which extend through the sidewalk. Expansion joints one (1) inch thick shall be placed wherever sidewalks abut against concrete driveways, concrete pavements, concrete curbs and/or concrete walks. Sidewalk shall be properly barricaded and lighted after finishing and shall be covered with tarpaulin or protective paper in case of threatening weather. After removal of forms, the space alongside the side- walk shall be filled with topsoil and leveled to present a finished appearance. PASSED this ? ~'~ day of ~) J. }1..t.~ day ,.
