(A) Grading.
(1) Where the surface of the ground will be higher than the finished grade of the sidewalk, driveway, or curb, the contractor shall do the necessary excavation to meet the finished grade of the sidewalk, driveway, or curb. Such grading shall include the necessary slopes.
(2) If the original surface of the ground is below the subgrade of the sidewalk, driveway, or curb, the contractor shall make an embankment on which to place the sidewalk, driveway, or curb; such embankment shall be placed in four-inch layers to a width as directed by the Village Engineer, with each layer thoroughly rolled or tamped to a compaction satisfactory to the Village Engineer. Topsoil or other organic material shall not be used as embankment under proposed sidewalk, each side shall be filled and finished graded as directed by the village.
(B) Work near street trees.
(1) In situations where the base of a tree has grown over the top of sidewalk, driveway, curb, or gutter that is to be removed, the concrete shall be removed from beneath the tree without disturbing the tree. New concrete shall be placed within the void, expansion paper placed and the sidewalk, driveway, curb, or gutter brought to finished grade. In no case should the wood be trimmed back without the written permission of the Village Engineer.
(2) If after removal of sidewalk, driveway, curb, or gutter, a tree root is located under the walk area and if that root is four and one-half inches in diameter or greater, the Village Engineer must be called to inspect the work. The Village Engineer will decide if the root may or may not be cut. The Village Engineer will give the contractor a written copy of the decision which must be presented to the above procedure will result in the contractor assuming liability for the affected tree as the law directs.
(C) Portland cement concrete sidewalk construction.
(1) Excavation for the walk shall be made to subgrade, and to a width of three inches more on each side than the width of the proposed walk. All tree roots exposed by excavation shall be cut off at least three inches outside the lines of the new walk and three inches below the subgrade, provided such approval has been received from the Village Engineer as identified under “work near street trees” above. After having been evenly fine graded, the subgrade shall be mechanically tamped and as specified in the Item 608 of the ODOT Construction and Material Specification. If springs are encountered, drains shall be laid as directed by the Village Engineer.
(2) Sidewalks shall be a minimum of four feet in width. The maximum width shall be six feet unless otherwise approved by the Village Engineer. Sidewalks shall be a minimum four inches thick except in driveways where they shall be a minimum seven inches thick. The surface of the walk shall have a transverse slope of one-fourth-inch per foot, with the low side adjacent to the roadway in accordance with Village Standard Drawing 100-7.
(3) The materials necessary for the construction of the concrete driveways, and forming, placing, finishing, and curing of the concrete driveways shall conform to ODOT Construction and Material Specification Section 451.10, 705.05, 705.06, 705.07, 705.08 and Standard Drawing 100-4, except as such specifications are modified herein.
(D) Portland cement concrete combined curb and gutter construction.
(1) Excavation for the curb and gutter shall be made to subgrade, and to a width of three inches more on each side than the width of the proposed curb and gutter. All tree roots exposed by excavation shall be cut off at least three inches outside the lines of the new curb and gutter and three inches below the subgrade, provided such approval has been received from the Village Engineer as identified under “work near street trees” above. After having been evenly fine graded, the subgrade shall be thoroughly compacted.
(2) Curb and gutter shall conform to Standard Drawing 100-3, unless deviation from this drawing is approved by the Village Engineer. The Village Engineer shall be notified by the contractor prior to setting forms if the adjacent curb and gutter cross section is different than Standard Drawing 100-3.
(3) The materials necessary for the construction of the concrete combined curb and gutter, and forming, placing, finishing, and curing of the concrete combined curb and gutter shall conform to ODOT Construction and Material Specification Section 609, except as such specifications are modified herein.
(4) Curb under-drains shall conform to specifications of the Village Engineer.
