(a) General Criteria. The design and location of streets shall conform to the following general criteria:
(1) Streets shall be arranged to provide for the continuation of existing streets. Extensions shall be provided to adjoining properties for future access.
(2) Local residential streets shall be arranged to discourage through traffic while providing for interconnection of neighborhoods and reasonable access for safety and service vehicles.
(3) Street arrangement, dimensions, and materials shall be designed to accommodate present and future planned traffic without requiring excessive consumption of land or materials or creating unnecessary costs for original construction, maintenance, repair, or replacement.
(b) Street Rights-of-Way and Pavement Width. Streets shall be platted and constructed with the following minimum widths in conformance with the plans and regulations of the City.
Street Type | Minimum Right-of-Way Width | Minimum Pavement Width |
Arterial | 100 feet | As approved by the Planning Commission |
Collector | 80 feet | 30 feet |
Local | 60 feet | 26 feet |
Cul-de-sac | 60 feet | 26 feet |
Boulevard | 80 feet | 18 feet each lane |
Alley | ||
Residential | 20 feet | |
Commercial or Industrial | 22 feet | |
The minimum pavement widths stated above shall be required for all streets, except that the Planning Commission shall have the authority to permit lesser pavement widths where on- street parking will be prohibited and the Commission determines that adequate off-street parking will be provided to meet the parking demand for the abutting land uses.
Right-of-way width shall be measured along a line perpendicular to the lines delineating the edges of the right-of-way and extending from one right-of-way line to the opposite right-of-way line.
Pavement width shall be measured along a line perpendicular to the edge of the pavement where it abuts the curb and extending from one such pavement and curb line to the opposite such line.
(c) Street Alignment
(1) Streets shall intersect as nearly as possible at an angle of 90 degrees, but not at less than 75 degrees nor at more than 105 degrees.
(2) Tangents at least fifty (50) feet long shall be introduced between reverse curves on collector streets.
(3) Where there is a deflection in the street alignment in excess of 10 degrees, a curve shall be inserted with a radius of not less than 200 feet for minor streets and not less than 500 feet for all other streets.
(4) Intersections shall be offset a minimum of 210 feet, measured from the intersections of the centerline of the streets. Intersections of more than two streets shall be prohibited.
(5) Curb corners shall be constructed with radii as approved by the Director of Public Works based on the width of the intersecting streets, the angle of intersection, the nature of vehicular and pedestrian traffic, and the Public Works Standards.
(6) Horizontal and vertical alignments, including centerline radius, sight distance, minimum gradient, maximum gradient, and vertical curve length shall conform to the Public Works Standards.
(d) Cul-de-sac Streets. The maximum length of a cul-de-sac street shall be 750 feet measured along the centerline from the intersection with the centerline of the intersecting street to the center of the turnaround. The Planning Commission may approve a greater length. Each cul-de-sac shall have a circular turnaround with a minimum pavement diameter of 90 feet and a right of way diameter of 120 feet or 30 feet greater than the pavement diameter. The Planning Commission may require a center island, provided that the subdivider must submit a plan for landscaping and perpetual maintenance for approval.
(e) Half Streets. Half streets, being streets platted or constructed with a right-of-way width or pavement width which is only a portion of that required by this Subdivision Ordinance for a full right-of-way or pavement width, shall be prohibited.
(f) Street Names and Designations. Street names shall be as approved by the Planning Commission. Names shall be selected so as to minimize confusion with existing street names in the City of Oberlin or in Lorain County.
(g) Alleys. Alleys may be approved in apartment, commercial and industrial districts. Alleys may be approved in one and two family districts as extensions of existing alleys.
(h) Pavement. Pavements of asphalt with concrete curb and gutter, or concrete with integral curb, shall be installed in conformance with the Public Works Standards. The pavement material may be specified by the Planning Commission for the purpose of compatibility with present or future planned streets.
Underdrains, curbs, subbase, storm water inlets, and other characteristics of street construction shall be in conformance with the Public Works Standards.
(i) Street Lighting. Street lights shall be installed in conformance with the Public Works Standards.
(j) Culverts and Bridges. Culverts and bridges shall be installed in conformance with the Public Works Standards.
(k) Driveway Aprons. Driveway aprons shall be installed from the sidewalk or street line to the curb at all driveway locations in conformance with the Public Works Standards.
