1166.01 STREETS.
   (a)   The arrangement, location, extent, width, grade, and character of all streets shall conform to the Comprehensive Land Use Plan and shall be appropriate to topography, to proposed uses of land abutting the streets, and to the pattern of surrounding streets and land use.
   (b)   The pavement design for street improvements shall be as outlined in the Ohio Department of Transportation’s (ODOT’s) “Pavement Design Manual for Local Roads and Streets”, but shall not be less than the typical design sections of Table 1.
   (c)   The integrity of the pavement structure depends upon the structural stability of the subgrade. All soil subgrade shall be prepared in accordance with ODOT’s Construction and Material Specifications Item 203.13.
   (d)   Existing or projected arterial and collector streets in adjoining areas shall be continued in new subdivisions, and local residential streets shall be continued, to prevent dead-end streets.
   (e)   Continuous through streets, other than arterial or collector streets, extending from one major street to another, should be avoided.
   (f)   Collector streets are satisfactory where there are no continuous cross streets, and if they exit onto only one arterial or collector street.
   (g)   No street arrangement shall be approved that prevents future access to adjoining undeveloped property.
   (h)   Local residential streets shall be designed so as not to offer direct routes to through traffic.
   (i)   Streets shall intersect as nearly as possible at right angles, and no street shall intersect any angle less than a 70 degree angle. No more than two streets should intersect at one point.
   (j)   Street jogs shall have centerline offsets of at least 125 feet.
   (k)   The right-of-way lines of the intersecting streets shall be connected at all corners with a curve having a radius of at least 50 feet for arterials, 40 feet for collectors, and 25 feet for local roads.
   (l)   When the line of a street changes direction a circular curve shall be provided. For local residential streets this curve shall be at least 200 feet in radius, and for all other streets at least 500 feet in radius. For all streets these radii shall be measured along the center line.
   (m)   On all but local residential streets, reverse curves shall be connected by a tangent of at least 100 feet.
   (n)   Vertical curves shall provide the sight distance suited to their location, as determined by the specifications of the City Engineer.
   (o)   All proposed streets and driveways which intersect with public streets and highways shall provide adequate sight distance meeting the requirements of the ODOT L&D Manual.
   (p)   Permanent dead-end streets or cul-de-sacs shall be used only where a continuous street cannot be developed.
      (i)   Dead-end streets designed to be so permanently shall be not longer than 600 feet and shall be provided at the closed end with a turn-around which shall have a minimum radius of 50 feet at the property line and a roadway radius of 38 feet.
      (ii)   T-shaped or Y-shaped turning areas in place of the circle may be permitted when the topography and shape of the lot makes such a design more desirable.
      (iii)   A temporary dead-end street may be permitted if it is part of a required street, a satisfactory turn-around is provided, and the total length is less than 200 feet.
   (q)   Half-streets shall be prohibited, except where essential to the reasonable development of the subdivision in conformity with the other requirements of this Ordinance, and where the Commission finds it will be practicable to require the dedication of the other half when the adjoining property is subdivided.
      (i)   Whenever an existing half-street is adjacent to a tract to be subdivided, the other half of the street shall be platted within such tract.
      (ii)   Half-streets shall not be less than one-half the standard width for the appropriate street classification.
   (r)   Any plat dedicating a temporary dead-end or a half-street shall include a plat restriction prohibiting any easement or right of access to the temporary dead-end or half street from any abutting or adjoining property save from lots platted in conformity with this Ordinance.
   (s)   Street right-of-way widths shall be not less than 80 feet for arterial streets, 60 feet for collector and local non-residential streets, and 50 feet for local residential streets.
   (t)   Street grades shall be not less than 0.5 percent. Grades shall not exceed five percent on local streets or eight percent on other streets, except in case of unusual topographic conditions. In no event shall any street grade exceed 10 percent.
   (u)   Profile grades shall be connected by vertical curves to provide adequate stopping sight distance for the following design speeds: local street, 35 miles per hour (MPH) (235 feet) sign distance; collector street, 50 MPH (350 feet) sight distance; and arterial streets, 60 MPH (475 feet) sight distance.
   (v)   Street widths measured from face of curb to face of curb shall be not less than three fifths the width of the required right-of-way.
