(a) Streets shall be logically related to the topography so as to produce usable lots, reasonable grades, a minimum of topographical or physical alterations and multiple access.
(b) Local streets shall be so laid out as to discourage their use by through traffic. Further, the arrangement of streets shall provide for the continuation of appropriate projection of the streets to serve the adjacent lands wherever topographic and other physical conditions permit.
(c) Where a subdivision abuts or contains an existing or proposed major highway of primary classification, the Planning Commission may require a frontage road, nonaccess reservation along the rear of the property contiguous to such highway or such other treatment as may be necessary for adequate protection of residential properties and to separate local and through traffic.
(d) Where a subdivision borders on or contains a railroad right of way or limited access highway right of way the Planning Commission may require a street approximately parallel to and on each side of such right of way at a distance suitable for the appropriate use of the intervening land. Such distances shall also be determined with regard for the requirements of approach grades and future separations.
(e) Buffer strips or lots intended to restrict access from adjacent private or public areas shall be prohibited.
(f) Double-frontage lots are prohibited, unless the street to the rear is a service road or alley. The Planning Commission may determine double-frontage lots or reverse-frontage lots are necessary to meet the objectives of Access Management, Section 1117.03.
(g) A tangent at least one hundred (100) feet long shall be introduced between reverse curves on arterial and collector streets.
(h) Streets shall be laid out so as to intersect as near as possible at right angles.
(i) Dead-end streets shall be prohibited except as stubs to permit further
street extensions into adjoining undeveloped tracts or when designed as cul-de-sacs.
(j) All street rights of way shall not be less than the width specified as follows:
STREET TYPE |

The minimum grade for collector or local streets shall be one-half (½) of one (1) percent.
(l) Cul-de-sacs are permitted where the street length does not exceed one thousand five hundred (1,500) feet and where a turn-around with a right-of-way radius of fifty (50) feet is provided. The pavement of a turning circle at the end of a cul-de-sac shall have a minimum radius of thirty-seven and one-half (37 ½) feet measured from vertical face of curb to vertical face of curb. The Planning Commission may require a right of way reserved for access to adjoining private or public land. Cul-de-sacs with islands shall have a minimum of thirty (30) feet of pavement width around the island measured from vertical face of curb to vertical face of curb.
(m) Streets shall be constructed to conform with the specifications as set forth by the Municipal Engineer which are to be considered as minimum standards.
(n) Minimum centerline radius for horizontal curves shall be as follows:
STREET TYPE |
RADIUS (feet) |
Arterial |
1000 |
Collector |
300 |
Local |

Cul-de-sac |
300 |
Service |
100 |
(o) No street name or plat name shall be used which will duplicate, or be confused with, the name of any existing street or plat in Licking County. Street names and plat names shall be subject to the approval of the Planning Commission.
(p) Roadway widths, vertical face of curb to vertical face of curb shall not be less than:
STREET TYPE |

(3) Profile Grade Approach to Intersection | 3% (max.) |
(4) Minimum Angle of Intersection | 75 degrees |
(5) Streets shall remain in the angle of intersection for at least 100 feet | (90 degrees preferred) |
