(a) Design and Arrangement.
(1) The arrangement of streets in new subdivisions shall make provision for the continuation of the principal existing streets in adjoining areas (or their proper projection where adjoining land is not subdivided) insofar as they may be deemed necessary for public requirements.
(2) The street arrangement shall be such as to not cause hardship to owners of adjoining property when they plat their own land and seek to provide for convenient access to it. Residential streets shall be so designed as to discourage through traffic, but offset streets should be avoided except as they are separated by not less than 125 feet at their access points on a collector street.
(3) The angle of intersection between minor streets and major streets should not vary by more than twenty degrees from a right angle.
(4) Residential streets shall be designed to discourage through traffic which may otherwise use secondary or major highways and whose origin and destination are not within the subdivision. Residential streets extending for considerable distance parallel to any secondary or major street should be avoided.
(5) Streets planned to serve multi-family, business or industrial areas shall connect directly to major or collector streets so as to not generate large volumes of traffic on local residential streets.
(6) The minimum curb radius shall be twenty-five feet to the face of the curb.
(b) Alignment.
(1) Minimum horizontal-radii of centerline curvature.
Degrees | Feet | |
Major Streets | 3 | 1,900 |
Collector Streets | 12 | 475 |
Minor Streets | 58 | 100 |
A minimum 100-foot tangent shall be introduced between reverse curves.
(2) Visibility requirements.
A. Minimum vertical visibility (measured 3.75 feet eye level to six inches above ground level):
600 feet on major streets.
350 feet on collector streets.
200 feet on minor streets.
B. Minimum horizontal visibility:
600 feet on major streets, measured on the center line.
350 feet on collector streets, measured on the center line.
150 feet on all other streets, measured on the center line.
(c) Street and Alley Width.
(1) The minimum right-of-way widths for streets and alleys are as follows:
Type of Street or Way | Minimum Right-of-Way Width or Variable Right-of-Way Width (Feet) |
Arterial Highway or Major Thoroughfare | Variable |
Secondary or Collector Streets | 60-70 |
Minor or Local Urban Streets | 60 |
Rural Roads and Streets serving Low Density Suburban Development | 60 |
Alleys | 30 |
(d) Cul-de-sacs. Each cul-de-sac shall be provided with a turn-around having a minimum right-of-way radius of sixty feet and maximum length of 530 feet measured from the intersection of the center lines of the entering intersection and including the turn-around. The outside of the pavement within the turn-around right of way shall have a minimum radius of fifty feet.
(e) Temporary Dead-end Streets. Streets designated to be dead-ended permanently shall not be permitted. Any dead-end street of a temporary nature, if longer than 200 feet or fronted by existing lots, shall have a temporary "T" type turn-around or cul-de-sac of the dimensions referred to in subsection (d) herein. There shall be provision made for the future extension of the street and utilities and there shall be a reversionary right to the land owners abutting the temporary turn-around for the excess right of way.
(f) Half-streets. Dedication of half-streets shall be discouraged. Where there exists a dedicated or platted half-street adjacent to the tract being subdivided, the other half shall be platted if deemed necessary by the Commission.
(g) Alleys. Alleys shall be avoided in single or two-family districts. They may, however, be required in multiple-dwelling developments. Alleys are required in the rear of all commercial and industrial lots if no other provisions are made for adequate service access or for access to parking. The rights of way of such alleys shall not be less than thirty feet and dead-end alleys shall not be permitted.
(h) Location. When a proposed subdivision is adjacent to or contains a State highway, the developer and the Commission should seek information from the Ohio Department of Transportation as to the status of the highway in reference to width and direction and also the type of access permitted to such highway.
(i) Street Grades (Vertical Curves). No street grade shall be less than one-half percent and shall not exceed the following, with due allowance for reasonable vertical curves:
Percent | |
Main or arterial thoroughfares | 4 |
Secondary thoroughfares | 6 |
Minor streets | 6 |
Cul-de-sacs | 8 |
(j) Street Grades (Cross-Section). For cross-section of streets see approved standard drawings.
(k) Street Names. Street names shall be selected which will not duplicate or be confused with the names of existing streets in the Municipality irrespective of modifying terms such as street, avenue or boulevard. Street names shall be subject to the approval of the Commission and wherever possible shall be in accordance with the following system:
General Direction | Over 1,000 Feet | Under 1,000 Feet |
North - South | Street | Place |
East - West | Avenue | Court |
Diagonal | Road | Way |
Curving | Drive | Lane or Circle |
(l) Acceptance of Streets. The Municipal Engineer shall, upon written request by the owner of the land upon which the street has been constructed, check the construction by stages. If the Municipal Engineer finds that such street is constructed in accordance with the specifications set forth on the approved plat and that such street is in good repair, then such finding, endorsed on the approved plat, shall recommend that Council accept the street for public use by the Municipality.
