   (a)   Pavements. The width of the pavement shall be measured from back to back of curbs. The Planning Commission, on the advice of the Director of Engineering, may require higher standards and/or greater widths than set forth above because of extraordinary traffic loads or unusual conditions in specific locations. A cul-de-sac shall have a minimum diameter of not less than 100 feet if fully paved. A cul-de- sac may have a planter in the center thereof but if a planter is provided the diameter of the cul-de-sac shall be of sufficient size as approved by the Planning Commission, City Engineer and the safety forces to permit all City vehicles to negotiate the cul-de-sac but in no case shall the pavement width be less than thirty feet measured from back to back of curbs.
      (Ord. 1983-58. Passed 9-1-83.)
The preparation of subgrade, the materials and the construction of pavement shall be in accordance with the standards of the City, the County Engineer or the Construction and Material Specifications of the Ohio Transportation Department, the January 1, 1971 edition, whichever is applicable or has jurisdiction, and as directed by the Director of Engineering.
After the underground utilities and house connections are installed and rough grading is complete, the roadway subgrade shall be shaped, rolled and compacted. The developer may construct the final pavement of reinforced concrete with integral curbs, or the developer may request to construct a temporary pavement of slag or stone for use during the building construction period and furnish a bond, in the amount required, guaranteeing that all pavements shall be maintained in a passable and reasonable condition, without expense to the City, until acceptance of final pavement for maintenance and use by the City.
      (1)   Temporary roadway. After the underground installations have been completed, the owner shall cause that area to be occupied by the future pavement to be excavated to a depth of at least fifteen inches below and parallel with the established finished pavement grade. Over such area he shall place a No. 12 slag (or comparable material) base, choked with slag screenings and rolled to a compacted thickness of at least eight inches. The surface of this base shall be maintained by the owner at not less than seven inches below finished grade at all times during the period in which building construction work is in progress and until such time that the final pavement work begins. The temporary roadway shall be maintained to the satisfaction of the Director of Engineering at all times.
If accepted by the Director, this material may be allowed to remain as an insulation course when the permanent concrete pavement is being installed.
      (2)   Permanent paving. No paving construction shall be started, other than that work required under subparagraph (1) above, until such time that trench backfill material has been allowed to reach its final settlement. This compaction can be acquired either by selected backfill, as directed by the Director, or by natural causes over a longer period of time, and also not until after permission to install such pavement has been granted by the Director. The pavement installations shall be made in accordance with the approved plans and under the inspection furnished by the City and paid for by the owner.
   (b)   Curbs and Gutters. Concrete curbs and gutters integral with the pavement shall be provided as required in the district where the subdivision is located. Mountable curbs shall not be used in Business and Industrial Districts. Mountable curbs and gutters shall be of the size as required by the Director.
   (c)   Driveways. Driveways shall be located in accordance with the development plan of the block and may be grouped in pairs or spaced separately.
The total pavement width at the curb shall be at least six feet wider than the width of the driveway or as directed by the Director. The grade of the apron shall not exceed five percent for a distance of ten feet from the sidewalk, and the maximum grade of the driveway shall not exceed ten percent.
      (Ord. 1989-47. Passed 2-16-89.)
   (d)   Public Sidewalks. Sidewalks shall be provided where feasible as determined by the Director of Engineering on both sides of the street in all districts.
      (1)   A.   All sidewalks shall be located in the public right of way, so that the edge of the walk is approximately one foot from the limit of the right of way, unless otherwise directed by the Director of Engineering.
            (Ord. 1993-102. Passed 5-6-93.)
         B.   No sidewalk shall have a grade separation of one-half inch or greater. Where such a separation occurs, it shall be eliminated through such necessary methods as filling gaps, ramping sudden changes in level, leveling or replacement.
      (2)   A.   On corner lots, each sidewalk shall be extended to the curb with a ramp where the sidewalk meets the street. Unless otherwise approved by the Director, these extensions shall be sloped to meet the street at a slope no greater than 1:12. The maximum rise for any run shall be thirty inches (760 millimeters). The minimum clear width of a ramp shall be thirty-six inches (915 millimeters) exclusive of flared sides. The cross ramp slope shall be no greater than 1:50.
         B.   The ramp surface shall be stable, firm and slip resistant. The ramp and their approaches shall be designed so that water shall not accumulate on walking surfaces. If gratings are located in walking surfaces, then they shall have spaces no greater than one-half inch (13 millimeters) wide in one direction. If the gratings have elongated openings, they shall be placed so the long dimension is perpendicular to the dominate direction of travel.
         C.   Transitions from ramps to walks, gutters or streets shall be flush and free of abrupt changes.
         D.   If a ramp is located where pedestrians shall walk across the ramp, or where it is not protected by handrails or guardrails, it shall have flared sides; the maximum slope of the flare shall be 1:10. Curb ramps with returned curbs may be used where pedestrians would not normally walk across the ramp.
         E.   Curb ramps shall be located or protected to prevent their obstruction by parked cars. Built up curb ramps shall be located so that they do not extend into vehicular traffic lanes. Curb ramps at marked crossings shall be wholly contained with the markings, excluding any flared sides.
         F.   If diagonal (or corner type) curb ramps have returned curbs or other well defined edges, such edges shall be parallel to the direction of pedestrian flow. The bottom of diagonal curb ramps shall have forty-eight inches (1220 millimeters) minimum clear space. If diagonal curb ramps have flared sides, they shall also have at least a twenty-four inch (640 millimeters) long segment of straight curb located on each side of the curb ramp and within the marked crossing.
      (3)   A.   No walk shall be less than five feet wide.
         B.   When a section of sidewalk currently existing at a width of four feet needs to be replaced, it shall not be replaced with a width of five feet unless the entire area of sidewalk needs to be replaced such that there shall not be an irregular pattern of four feet and five feet sections existing in the same area. An area may include an entire street or the area between two driveways. When a deficient four foot wide section of sidewalk existing in a driveway, it may remain at four feet until such time as the driveway is replaced. At that time the sidewalk shall be built to be five feet wide.
         C.   A sidewalk shall not be caused to be less than four feet where the existing adjacent walks are four feet, or five feet upon replacement subject to subsection (d)(3)B. hereof, by any other existing structure or obstacle. In a situation where a structure or obstacle lies in the path of the sidewalk, the structure or obstacle shall be modified to allow the proper width and/or alignment within the public right-of- way or an easement shall be obtained from property owners to allow the proper alignment and/or width of the walk.
         D.   Sidewalks shall be constructed of Portland concrete cement not less than four inches thick with 6 x 6 - 10/10 welded wire fabric, except that where they are crossed by driveways, they shall not be less than six inches thick and all sidewalks shall be in accordance with other City standards for construction.
            (Ord. 1993-25. Passed 2-4-93.)
      (4)   Once eighty percent (80%) of the dwelling units within the new development or subdivision are completed, the owner of the property shall cause sidewalks to be installed in accordance with City standards within sixty days, weather permitting, or the City may cause such sidewalks to be installed at the owner’s cost. (Ord. 1995-75. Passed 9-21-95.)
   (e)   Curbs at Pedestrian Crosswalks. All new curbs that are authorized to be constructed under these Subdivision Regulations, and all existing curbs which are part of any reconstruction, shall have a ramp with a nonslip surface built into the curb at each pedestrian crosswalk so that the sidewalk and street blend into a common level. Such ramps shall not be less than forty inches wide and shall, insofar as feasible, be constructed in accordance with the standard drawings and specifications for curb ramps of the Ohio Department of Transportation and the applicable provisions of the Ohio Building Code, which drawings and specifications of the Ohio Department of Transportation and applicable provisions of the Ohio Building Code are hereby adopted and approve and made a part hereof as though fully rewritten herein.
