1246.03 STREET PLANNING.
   In addition to relating streets to topography as suggested in Section 1246.02, streets shall be designed according to the function served, the use of abutting land and standards of width, intersections, maximum grades and curvatures, as set forth in the following subsections.
   (a)    Major streets function primarily for the movement of fast traffic between points of heavy traffic generation and, unless shown otherwise on the Thoroughfare Plan, they shall be planned for continuation of existing streets in the system at the same width or greater width in accordance with adopted Municipal standards. Major streets shall contain as few intersections as possible. Where a subdivision of one- family dwellings adjoins a major street, the City Planning Commission may require the developer to prepare sketches and estimates of a plan based on marginal access streets or such treatment as the fronting of lots on perpendicular local streets in order to protect the residential property from the movement of heavy traffic and eliminate driveways cutting into a major street. The Commission may require a plan wherein lots do not have direct access onto the major street or require a setback of such depth that marginal streets can be constructed in the future.
   (b)    Secondary streets function for collecting traffic from local streets and distributing it onto major streets. They will normally contain a relatively large number of intersections with local streets and few with main streets. Secondary streets shall be planned for continuity and to lead more or less directly to one or more focal points or centers of traffic generation.
   (c)    Local streets shall provide direct and full access to each lot. They shall be planned for convenient circulation toward the principal directions of travel, bus routes, schools and playgrounds. The layout shall be related to the topography and natural features. The street pattern shall be indirect and yet continuous to prevent through traffic; formed of straight, moderately curved, loop, angular or ell streets. Tee- intersections shall predominate, cross-intersections shall be avoided. There shall be an underlying systematic neighborhood pattern, except that gridiron and other rigid geometrical patterns shall be avoided. The street pattern shall include extensions to the boundaries of the development to provide circulation between adjoining neighborhoods.
   (d)    Pedestrian ways of not less than twenty-five feet right of way, and in a straight line, may be required across blocks exceeding 1,500 feet in length or at the end of cul-de-sac streets for access to schools, playgrounds, bus stops or other public facilities where convenient pedestrian circulation has not been provided by streets.
   (e)    Street extensions shall be planned where a subdivision adjoins unsubdivided land. Certain streets shall extend to the boundary lines so that all parcels may be subdivided and a coordinated street system obtained. A temporary turnaround or background shall be provided for each street extension if it is more than 200 feet in length and if lots front thereon. Provision shall be made for future extension of the street and utilities and such provision shall be noted on the final plat.
   (f)    Reserve strips adjoining streets, or other provisions to control access or extensions to pavement and/or utilities to a nearby property, shall not be permitted except where the control and disposal of land comprising such strips has been assigned to the City under conditions approved by the Commission.
   (g)    Intersections of streets shall be designed to be as nearly at ninety degrees as possible, and no street shall intersect another at less than sixty degrees. The intersection of more than two streets at a point or with center line offsets of less than 125 feet shall not be permitted. Property lines at street intersections shall be rounded with a radius of not less than thirty feet for major streets and twenty feet for secondary streets and for local streets.
   (h)    Right-of-way widths shall be as follows.
      (1)    Local streets. Right-of-way widths shall not be less than the following:
         A.    Non-through streets, less than 1,500 feet in length: sixty-foot right of way.
         B.    Through streets or non-through streets longer than 1,500 feet, and where extra width is necessary for grading or placement of utilities: sixty-foot right of way.
         C.    Cul-de-sac, less than 500 feet in length: sixty-foot right of way; more than 500 feet but less than 1,000 feet in length: sixty-foot right of way. Turnaround: pavement outside diameter-ninety feet; property line diameter-130 feet; or such larger diameters as may be required by the City Engineer based upon the proposed usage.
      (2)    Secondary streets. The right of way shall be in accordance with the thoroughfare plans and standards and may vary from sixty to eighty feet.
      (3)    Major streets. The right of way shall be in accordance with State highway or County or Municipal thoroughfare plans and standards, and may vary from eighty to 120 feet.
   (i)    Grades of streets in vertical alignment shall not exceed ten percent for local streets, seven percent for secondary streets and six percent for major streets. Street grades shall be not less than one-half percent in order to provide adequate surface drainage.
   All changes in grade shall be connected by vertical curves, and the rate of change of grade shall not exceed four percent per 100 feet. Streets shall level off to a grade not exceeding three percent for a distance of not less than seventy-five feet from each side of an intersection.
   (j)    Angles in the alignment of street lines, horizontal alignment, shall be connected by a curve with a radius on the center line of not less than 200 feet for local streets.
   (k)    Street names shall be selected which will not duplicate or be confused with the names of existing streets in Cuyahoga County irrespective of modifying terms such as street, avenue, boulevard, etc. Streets that are or will eventually be continuations of existing or platted streets shall be named the same as such streets. Street names shall be subject to the approval of Council.
