(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.)
(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.)
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.)
(a) For the safety of pedestrians and of children at play, installation by the developer of sidewalks on both sides of streets will normally be required. The Commission may waive the requirements of sidewalks where park, railroad or other use on one side of a street makes a sidewalk nonessential.
(b) Sidewalks shall be located not less than one foot from the property line to prevent interference or encroachment by fencing, walls, hedges or other planting or structures placed on the property line at a later date. In single-family residential areas concrete sidewalks shall be four feet wide and four inches thick. In multi-family or group housing developments sidewalks shall be five feet wide and ten feet wide in commercial areas.
(Ord. 920. Passed 7-23-56.)
(a) After grading is completed and approved and before any base is applied, all of the underground work, water mains, gas mains, etc., and all service connections shall be installed completely and approved throughout the length of the road and across the flat section. All driveways for houses to be built by the developer shall be cut and drained.
(b) All utilities shall be placed in streets before roadway surfacing is attempted. Taps for sewer, water, gas and any other utilities underground shall be taken to the property line before roadway surfacing is done. This will protect and preserve streets thus minimizing future repair work.
(Ord. 920. Passed 7-23-56.)
(a) Water mains properly connected with the community water supply system or with an alternate supply approved by the County Health Officer shall be constructed in such a manner as to adequately serve all lots shown on the subdivision plat for both domestic use and fire protection.
(b) The sizes of water mains, the location and types of valves and hydrants, the amount of soil cover over the pipes and other features of the installation shall be approved by the Planning Commission and shall conform with accepted standards of good practice for municipal water systems.
(Ord. 920. Passed 7-23-56.)
