1123.03 REGULATIONS AND SPECIFICATIONS.

   Covering streets, sanitary sewers, water lines, storm sewers and other public utilities:

   (a)   Each project shall have a complete set of working drawings and typical sections covering all the improvements prepared in accordance with the detailed specifications on file and approved by the Safety-Service Director.

   (b)   All improvements shall be made under supervision of the Safety-Service Director or his approved representative.

   (c)   Detailed specifications required for all improvements are on file in the City offices. It would be advisable for each developer to thoroughly acquaint himself with their requirements before preparation of working plan.

      (Ord. 920. Passed 7-23-56.)

1123.04 MONUMENTS.

   (a)   Concrete monuments four inches in diameter or square, three feet long, with a flat top, shall be set at all street corners, at all points where the street lines intersect the exterior boundaries of the subdivision, and at angle points and points of curve in each street, the top of the monument shall have an indented cross or pin wherever it is practical to identify properly the location and shall be set flush with the finished grade.

   (b)   All other lot corners shall be marked with a standard survey pin or iron not less than three-fourths inches in diameter and twenty-four inches long and driven so as to be flush with finished grade.

(Ord. 920. Passed 7-23-56.)

1123.05 GRADING.

   All streets, roads and alleys shall be graded to their full width by the subdividers so that pavements and sidewalks can be constructed on the same level plane. Due to special topographical conditions, deviation from these standards will be allowed only with special approval of the Planning Commission.

   (a)   Preparation. Before grading is started the entire right-of-way area shall be first cleared of all stumps, roots, brush and other objectionable materials and all trees not intended for preservation.

   (b)   Cuts. All tree stumps, boulders and other obstructions shall be removed to a depth of two feet below the subgrade. Rock, when encountered, shall be scarified to a depth of twelve inches below the subgrade.

   (c)   Fill. All suitable material from roadway cuts may be used in the construction of fills, approaches, or at other places as needed. Excess materials including organic materials, soft clays, etc., shall be removed from the development site. The fill shall be spread in layers not to exceed twelve inches loose and compacted by a sheep's foot roller. The filling of utility trenches and other places not accessible to a roller shall be mechanically tamped, but where water is used to assist compaction, the water content shall not exceed the optimum of moisture.

      (Ord. 920. Passed 7-23-56.)

1123.06 STORM DRAINAGE.

   (a)   An adequate drainage system, on all streets, including necessary open ditches, storm sewers, pipes, culverts, intersectional drains, drop inlets, bridges, etc., shall be provided for the proper drainage of all surface water. Culverts shall be provided to accommodate all natural water flow, and shall be of sufficient length to permit full width roadway, and the required slopes. The size openings to be provided shall be determined by Talbot's formula, but in no case shall the pipe be less than twelve inches. Culverts shall be built on straight line and grade, and shall be laid on a firm base but not on rock. Pipes shall be laid with the spigot end pointing in the direction of the flow and with the ends fitted and matched to provide tight joints and a smooth uniform invert. They shall be placed at a sufficient depth below the roadbed to avoid dangerous pressure of impact, and in no case shall the top of the pipe be less than one foot below the roadbed.

   (b)   Storm sewers shall be either bell and spigot or tongue and grooved pipe, either clay, concrete or plastic (SDR-35) and shall have a minimum length of thirty inches per unit. Size of storm sewer shall be approved by the Safety-Service Director or by the City Engineer, but in no case shall the sewer be less than eight inches in diameter.

(Ord. 920. Passed 7-23-56.)

1123.07 ROADWAY SURFACING.

   (a)   The minimum standards for roadway surfacing shall be those detailed in subsection (1) or (2) hereof.

      (1)   After preparation of the subgrade, the roadbed shall be surfaced with material required by local standards. The minimum asphalt concrete base shall be four and one-half inches and the minimum asphalt concrete finish surface shall be one and one-half inches. All surfacing shall be a minimum six inches full depth asphalt pavement and be approved by the City.

         All soft spots in subgrade shall be removed and replaced with crushed stone then compacted before surfacing begins. Drainage for the roadway shall be provided.

      (2)   As an alternative two courses of compacted asphaltic concrete shall be constructed on the prepared base, in accordance with these specifications and in conformity with the lines, grades, designed thickness, typical cross sections and other details shown on the plans, finished and ready for acceptance.

            A wearing course of bank or crusher run aggregate shall be placed on the completed and accepted subgrade or subbase. The aggregate material shall conform with the requirements of Item 304.02 of the Ohio State Highway Specifications and be uniformly spread in layers by means of an approved spreader box or any other method approved by the Engineer.

         (Ord. 20-71-0. Passed 5-24-71.)

            After spreading, the material shall be rolled until thoroughly compacted. The minimum compacted thickness of the aggregate wearing course shall not be less than seven inches.

   After compaction of the wearing course, a prime coat of tack coat of bituminous material shall be applied, followed by the application of two and one-half inches of asphaltic concrete applied in two separate layers, the first layer consisting of one and one-quarter inches leveling course. The second shall be one and one-quarter inches finish or wearing course.

   The asphaltic concrete shall be composed of a mixture of coarse and fine mineral aggregate and asphalt cement. The several courses shall be of the composition known as Asphaltic concrete, Item 402, Item 403 or Item 404 as described in Ohio State Highway Specifications. Drainage for the roadway shall be provided.

         (Ord. 20-71-0. Passed 5-24-71.)

1123.08 MINIMUM PAVEMENT WIDTHS.

   Due to the diversity of development in the planning region ranging from sparsely populated agricultural areas to the densely populated urban areas, required pavement widths will necessarily vary with the character of building development and the amount of traffic encountered. Minimum pavement widths shall be measured from back of curb to back of curb as follows:

   (a)   On minor residential streets the minimum width shall be thirty-two feet. Most minor streets in the residential developments or rural roads involving parking and/or considerable traffic.

   (b)   On collector streets the minimum width shall be thirty-six feet, including minor streets which in the opinion of the Planning Commission will involve sufficient traffic and/or parking to justify such width.

      (Ord. 10-81-0. Passed 4-13-81.)

1123.09 CURBS AND GUTTERS.

   The subdivider shall provide permanent six inch concrete curbs with twenty-four inch integral concrete gutters; except with the approval of the Planning Commission a roll type curb and gutter may be used on a minor residential street.
