(a) The primary function of local streets is to provide direct access to abutting developments. The local street system should be designed to minimize through traffic movements. This can be accomplished by designing a system of collector streets and by creating discontinuities in the local street pattern, by offsetting local street intersections and providing continuous loop and angular streets. Every part of a residential area should be interconnected for convenience and to avoid excessive indirect travel except where connections are not feasible because of topographic conditions.
(b) The pattern should be logical and comprehensive for the convenience of local residents and visitors and for providing services. The design should be planned to provide these basic functions so as not to need to rely on extensive traffic regulations. The streets should be designed for uniformly low volumes of traffic, commensurate with residential amenities, to discourage speeds of more than twenty-five (25) miles per hour. The amount of space devoted to local streets should be minimized for costs and economy of land use.
(c) There should be a basic underlying design related to the topography and natural features. The pattern should also be related to attaining functional, economical and practical patterns and shapes and sizes of areas for development. Necessary traffic generators such as schools, bus routes and playgrounds should serve as focal points in the pattern and such routes should have a minimum number of pedestrian crossings. There should be a minimum number of intersections. T-intersections should predominate and cross-intersections should be minimized.
(1) Right of Way and Pavement Widths (Standard). Whenever the local street pattern is planned to assure low traffic volumes, fifty (50) foot (15.24m) rights of way, otherwise, sixty (60) foot (18.29m) rights of way; pavement width of twenty-six (26) feet (7.83m) back to back of curbs on cul-de-sacs and loop streets, thirty-two (32) feet (9.75m) on other local streets, and thirty-six (36) feet (10.97m) on collector streets. Arterial streets shall be paved in accordance with City requirements on an individual consideration basis.
(2) Intersections (Criteria). Designed so streets shall intersect at approximately ninety (90) degrees, but in no case less than seventy-five (75) degrees. Centerline offsets or jogs of T-intersections shall not be less than one hundred twenty-five (125) feet (38.10m). At intersecting streets, an unobstructed sight triangle shall be maintained of not less than twenty (20) feet (6.10m), measured along the nearest intersecting front property lines. Property lines at street intersections shall be rounded with a radius of not less than twenty (20) feet (6.10m) for local streets.
(3) Grades or Vertical Alignment (Standard). The minimum grade should be not less than three tenths (.3) of one (1) percent for local and collector streets. The maximum grade within one hundred (100) feet (30.48m) of an intersection should not exceed three percent (3%).
(4) Horizontal Alignment (Criteria). Curving local streets are encouraged in residential districts where related to topography or other functional features; a minimum curve of one hundred (100) foot (30.48m) radius measured from the inside edge of the pavement; minimum tangent fifty (50) feet (15.24m), a minimum sight distance of two hundred (200) feet (60.96m).
(5) Cul-de-sac Streets (Criteria). Where approved, cul-de-sacs shall terminate with a permanent turn-around, having a minimum outside curb radius of fifty (50) feet (15.24m), property line radius of sixty (60) feet (18.29m), and shall not exceed one thousand (1000) feet (304.80m) in length. The Commission may require that the center circle, or oval, be paved. If the cul-de-sac street does not open in the direction of schools or playgrounds, a pedestrian way may be required.
(6) Temporary Dead-End Streets (Standard). Where a proposed subdivision adjoins undeveloped land, temporary "T" turn-arounds may be permitted provided provisions are made for the future extension of such streets and utilities, and for the reversion of the excess rights of way to the abutting properties. Permanent dead-end streets are not permitted.
(7) Streets of Nonconforming Width (Standard). Streets of less than the required right of way shall not be permitted except where the Commission finds it would not be reasonable to require dedication of the remaining part until the abutting property is subdivided. Wherever property abuts a street which does not conform to the width required by either the Street Plan or plans of Cuyahoga County or the Ohio Department of Transportation, the additional width shall be provided when the land is subdivided.
(8) Reserve Strips Adjoining Streets (Standard). An intervening division of land which controls access or extensions of pavement and utilities to adjoining property shall not be permitted except where the control of such land has been assigned to be under the control of the City.
(9) Driveways. Driveways shall be located in accord with a plan for the block and on corner lots not less than sixty (60) feet (18.29m) from the nearest intersecting street right-of-way lines.
(10) Street Names (Criteria). Names shall not duplicate unless directly connected or related with the names of existing streets in northwestern Cuyahoga County; the names shall be subject to the approval of the Commission.
