In addition to relating streets to topography, as required in Section 1127.02(a), 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. Major streets function primarily for the movement of fast traffic between points of heavy traffic generation and, unless shown otherwise on the Thoroughfare Plan, shall be planned for continuation of existing streets in the system at the same width or greater width in accordance with adopted City standards. Major streets shall contain as few intersections as possible. Where a subdivision of one-family dwellings adjoins a major street, the Planning Commission may require the developer to prepare sketches and estimates of a plan based on marginal access streets or such other treatment as the fronting of lots on perpendicular local streets in order to protect the residential property from the movement of heavy traffic and to eliminate driveways cutting into a major street, and it 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. Secondary streets function for the collection of traffic from local streets and for the distribution of traffic onto major streets. They normally contain a relatively large number of intersections with local streets and a few with major streets. Unless shown otherwise on the Thoroughfare Plan, a secondary street system may be required wherever a residential neighborhood surrounded by major streets is designed to serve over 500 dwelling units.
(c) Local Streets. Local streets function to 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 street pattern shall be sufficiently indirect to discourage through traffic.
Three-way or "T" intersections shall predominate; four-way or cross-intersections shall be avoided.
(d) Extension of Streets. Where a subdivision adjoins unsubdivided land, certain streets shall be planned to extend to the boundary lines so that all parcels may be subdivided and a coordinated street system obtained. A temporary turn-around or back-around shall be provided for each such street extension if more than 300 feet in length and if lots front thereon. Provisions shall be made for future extension of the street and utilities and so noted on the final plat.
(e) Nonconforming Widths. Where property abuts a street which does not conform to the width required by Thoroughfare Plans of the City or by the County or State Transportation Department, or by these Land Planning and Subdivision Regulations, the additional width shall be dedicated when such land is subdivided. Streets of less than the required width shall not be permitted.
(f) Reserve Strips Adjoining Streets. 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 provisions for the control and disposal of land comprising such strips has been assigned to the City under conditions approved by the Planning Commission.
(g) Multi-Family Developments. Public and private streets for multi-family developments shall be planned to connect only with major or secondary streets so that large volumes of traffic will not be generated on local residential streets. Vehicular and pedestrian access shall be planned so that a street, service drive, parking area or delivery area will be located not more than 100 feet from main or service entrance of a building and will be available for each dwelling unit.
(h) Business and Industrial Development. Streets for business and industrial developments shall be planned to connect only with major streets so that large volumes of traffic will not be generated on local residential streets. The intersection of service streets or access driveways to parking areas, with major streets shall be located so as to cause the least possible interference with the movement of traffic on the major streets. Access driveways (measured on centerline) shall be located not less than fifty feet from the right-of-way line of the nearest intersecting street and spaced at not less than 130-foot intervals. Where possible, parking areas serving adjoining business establishments shall be interconnected by drives. The Commission may require the dedication and improvement of marginal service roads along major streets abutting such developments.
(i) Intersections. Streets shall be designed to intersect 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 one point shall not be permitted. The center lines of two streets generally opposite, when intersecting a third street, shall be offset no less than 125 feet or shall have no offset.
Property lines at street intersections shall be rounded with a radius of not less than thirty feet for major streets, twenty-five feet for secondary streets and twenty-five feet for local streets unless determined otherwise by the Director of Engineering.
(j) Right-of-Way Widths.
(1) One and two-family developments. Local streets shall have right-of-way widths of not less than sixty feet except as follows:
A. The turn-around of a cul-de-sac shall have a diameter of not less than 125 feet. A "T" and "Y" turn-around may be approved by the Planning Commission in unusual locations.
B. Marginal access streets abutting a major street shall have a minimum right-of-way width of not less than forty feet.
(2) Multi-family, business and industrial streets. For multi-family, business and industrial streets the right of way shall be determined for each development, but in no case shall the right of way be less than sixty feet. The pavement width shall be sufficient to safely accommodate the maximum traffic, parking and loading needs and access for fire protection equipment.
(3) Secondary streets. Secondary streets shall be consistent with the Thoroughfare Plan and standards. The right-of-way width may vary from sixty to eighty feet.
(4) Major streets. Major streets shall be consistent with State Highway Department, County or City Thoroughfare Plans and standards. The right- of-way width may vary from eighty to 120 feet.
(k) Grades. Vertical alignment shall not exceed ten percent for local streets, seven for secondary streets and six percent for major streets. Street grades shall be not less than 0.4 percent in order to provide adequate surface drainage.
Streets shall level off to a grade not exceeding three percent for a distance of not less than seventy-five feet from the right of way of an intersecting street. All changes in grade shall be connected by vertical curves. The rate of change of grade of such curve shall not exceed three percent.
(l) Curvature of Streets (Horizontal Alignment). Angles in the horizontal alignment of center lines of streets shall be connected by a curve with a radius of not less than 150 feet for local streets, 300 feet for secondary streets and 500 feet for major streets. Between reverse curves there shall be a center line tangent of not less than 200 feet long on major and secondary streets and not less than 100 feet long on local streets.
(m) Street Names. Street names shall be selected which will not duplicate or be confused with the names of existing streets in western 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. Street names shall be subject to the approval of the Planning Commission and, wherever possible, shall be in accordance with the following system:
General Direction | Long Continuous | Short Disconnected |
North-south | Streets | Courts |
East-west | Avenues | Places |
Diagonal | Roads | Ways |
Curving | Drives-boulevards | Lanes or circles. |
