CHAPTER 1117
Design Standards
1117.01 EVALUATION OF PLANS.
The Subdivision and Development Regulations, principles, standards and requirements set forth herein shall be applied by the Planning Commission in evaluating the proposed subdivision plans submitted for their consideration. However, if physical conditions interfere, the Planning Commission may recommend deviation from the established requirement so as to carry out the overall intent of these standards. (Ord. 21-95. Passed 8-2-95.)
1117.02 STREETS AND HIGHWAYS.
(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.

street extensions into adjoining undeveloped tracts or when designed as cul-de-sacs.

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.
