(A) Completion of Improvements. No final official plat of any subdivision shall be approved unless all the improvements required by this chapter have been completed prior to the filing of such plat with the Planning Commission for final approval in accordance with these Subdivision Regulations and under the supervision of the officials having jurisdiction thereof.
(B) Bond in Lieu of Performance. In lieu of completion of such improvements, the following procedures may be followed:
(1) Subdivisions within the City. In lieu of completing the improvements required in subsection (A) hereof, the subdivider shall furnish the Planning Commission and the City with a performance bond in the form of cash or a certified check or a bond issued by a recognized surety company, acceptable to the Commission. The form of such bond shall be acceptable to the Director of Law. Such bond shall be payable to the City and shall be sufficient to cover the cost of any or all required improvements, as estimated by the City Engineer, thereby to secure the actual construction and installation of such improvements within the period of time required in Section 1220.13(B). The estimated cost shall include the cost of all inspections required herein based on the hourly compensation of the inspector or inspectors for the time necessary to make such inspections within the subdivision.
(2) Subdivisions outside the City. In lieu of completing the improvements required in subsection (A) hereof, the subdivider shall furnish the Planning Commission and the City with a performance bond in the form of cash or a certified check or a bond issued by a recognized surety company, acceptable to the Commission. The form of such bond shall be acceptable to the Director of Law. Such bond shall be payable to the City and shall be sufficient to cover the cost of any or all required improvements, as estimated by the City Engineer or an engineer authorized by the Commission to estimate such costs, thereby to secure the actual construction and installation of such improvements within the period of time required in Section 1220.13(B). The estimated cost shall include the cost of all inspections required herein, based on the hourly compensation of the inspector or inspectors for the time necessary to make such inspections within the subdivision.
(Ord. 110-61. Passed 7-17-61.)
(A) Grading. Streets shall be graded to the full width and completely constructed with an all-weather surface roadway complete with curbs of the wall type or combined curbs and gutters. All construction shall be approved by the City Engineer or the County Engineer, as provided in Section 1220.12, according to the standards and specifications which are on file in their respective offices and which are incorporated herein by reference.
(B) Pavement; Construction Costs. The width of pavement on all streets shall be not less than twenty-eight feet, measured from curb face to curb face. In the case of highways and major and secondary streets, as designated in the Master Plan, arrangements shall be made through the City Engineer or the County Engineer to pave these streets to their recommended widths, the subdivider being required to bear the cost of the twenty-eight foot portion only. The cost of curb and gutter construction shall in all cases be borne by the subdivider.
(C) Master Plan. The Master Plan is hereby defined as the Comprehensive Plan (which may consist of several maps, data, etc.) prepared by Harland Bartholomew and Associates, City Planners, St. Louis, Missouri, in association with Carroll V. Hill and Associates, Dayton, Ohio, August, 1957, or any portion thereof, adopted by the Planning Commission on March 23, 1960, and any amendments thereto, showing the general location and extent of the physical facilities of the City, including major streets and main thoroughfares, parks, schools and other public open spaces and public building sides. (Ord. 72-70. Passed 4-13-70.)
(D) Design Standards.
(1) Generally. The design and improvement standards contained in Table 1 following Chapter 1222 are suggested minimums for all streets. All streets shall be designed and constructed in accordance with the standards specified in Table 1.
(2) Horizontal alignment. When there is an angle of deflection of more than five degrees between two centerline tangent sections of a street, a curve of adequate radius shall connect them (See Table 1.) Between reverse curves, a minimum tangent of 100 feet shall be introduced.
(3) Vertical alignment.
(a) All changes of grade shall be connected by vertical curves of minimum length in feet equal to twenty times the algebraic difference in the rate of grade for arterials and industrial streets and fifteen times such difference for collector and local streets.
(b) Minimum vertical visibility shall conform to Table 1 and the Ohio Department of Transportation's regulations in effect on the date of the approval of the preliminary plat.
(c) No street grade shall be less than 0.60 percent and in no case shall a street grade be more than three percent within 100 feet of an intersection.
(4) Intersection design standards.
(a) The design and improvement standards for intersections are suggested minimum standards for all street intersections in a subdivision. These standards are included in Table 1. Streets shall remain tangent for at least 100 feet beyond the point of intersection. The minimum angle of intersections shall be seventy-five degrees with ninety-degree intersections preferred.
(b) Multiple intersections involving junctions of more than two streets are not permitted.
(c) Four-way intersections of local streets should be avoided and threeway or T-intersections should be encouraged wherever possible.
Sidewalks shall be of such width and construction as are approved by either the City Engineer or the County Engineer, as provided in Section 1220.12, according to the standards and specifications which are on file in their respective offices and which are incorporated herein by reference. Such sidewalks shall be constructed:
(A) Along both sides of streets where lots average 100 feet or less in width;
(B) Along one side of streets where lots average more than 100 feet but less than 200 feet in width;
(C) At the option of the subdivider where lots average 200 feet or more in width; and
(Ord. 72-70. Passed 4-13-70.)
(D) At the option of the subdivider when all of the following are true:
(1) The subdivision consists of only one street forming a closed loop, with no intersecting streets;
(2) The adjacent subdivision through which access to public streets is provided contains no sidewalks; and
(3) No possible adjacent future development of any subdivision exists on any side of the proposed subdivision.
This section shall not be construed as limiting or affecting the right of any person to petition a sidewalk assessment project, or the right of the City to require such assessment project, after development of a subdivision.
(Ord. 56-77. Passed 3-21-77.)
Every subdivision shall be provided with a storm water sewerage or drainage system adequate to serve the area being platted and approved by the officials having jurisdiction thereof.
All necessary facilities, including underground pipes, inlets, catch basins, culverts or open drainage ditches, shall be installed to provide for the adequate disposal of surface water and to maintain any natural drainage course.
(Ord. 110-61. Passed 7-17-61.)
