(Prior Code, § 7.8)  (Ord. 7-05, passed 6-13-2005)
§ 151.053  MARGINAL ACCESS STREETS.
   (A)   Where a subdivision abuts or contains an existing or proposed arterial street, the city may require access streets, reverse frontage with screen planting contained in a non-access reservation along the rear property line, deep lots with rear service alleys, or other treatment as may be necessary for adequate protection of residential properties and to afford separation of through and local traffic.
   (B)   Where the proposed subdivision abuts upon or contains an existing or proposed arterial street or highway or which traffic volumes and vehicular speeds warrant special safety considerations, the city may require that marginal access streets be provided in order that no lots front on the existing or proposed arterial street or highway.
   (C)   Where a subdivision borders on or contains a railway right-of-way or limited access highway right-of-way, the city may require a street approximately parallel to and on each side of the right-of-way, at a distance suitable for the appropriate use of the intervening land, as for park purposes in residential districts. The distances shall also be determined with due regard for the requirements of approach grades and future grade separations.
(Prior Code, § 7.9)
§ 151.054  STREET JOGS.
   Street jogs with center line offsets of less than 150 feet shall be prohibited. Cul-de-sacs, minor terminal or dead-end streets or courts which are designed so as to have one end permanently closed shall not be longer than 500 feet and shall be provided at the closed end with a turnaround having a radius at the outside of the right-of-way of at least 60 feet.
(Prior Code, § 7.10)
§ 151.055  STREET NAMES.
   Proposed streets which are in alignment with other already existing and named streets shall bear the names of the existing streets. The name of a proposed street which is not in alignment with an existing street shall not duplicate the name of any existing street, irrespective of the use of the suffix street, avenue, boulevard, drive, place, court, lane, road, pike, highway, parkway or similar suffix. Whenever a street alignment changes direction more than 45 degrees without a return to the original alignment within a distance of 500 feet, then the name of the street shall be changed at the point of curvature. Whenever a cul-de-sac street serves not more than three lots, the name of the intersecting street shall apply to the cul-de-sac. To avoid duplication and confusion, the proposed names of all streets shall be approved by the designated City Engineer prior to the names being assigned or used.
(Prior Code, § 7.11)
§ 151.056  PRIVATE STREETS AND RESERVE STRIPS.
   There shall be no private streets platted within a subdivision. There shall be no reserve strips in a subdivision, except where their control is definitely vested in the city or county under conditions approved by the Council as authorized herein.
(Prior Code, § 7.12)
§ 151.057  GRADING SPECIFICATIONS.
   All streets, roads and alleys shall be graded to their full widths by the subdivider, so that street pavements and sidewalks can be constructed on the same level plane. Deviation from this standard due to special topographical conditions will be allowed only with the approval of the City Council. Before grading is started, the entire right-of-way area shall be first cleared of all tree stumps, roots, brush and other objectionable materials and of all trees not intended for preservation. The subgrade shall be properly shaped, rolled and uniformly compacted to conform with the accepted cross-section and grades. In cuts and fills, all tree stumps, boulders, organic material, soft clay, spongy material and other objectionable materials shall be removed to a depth of at least two feet below the graded surface. This objectionable matter, as well as similar matter from cuts, shall be removed from the right-of-way area and disposed of in a manner that it will not become incorporated in fills or hinder proper operation of the drainage system.
(Prior Code, § 7.13)
§ 151.058  MINIMUM PAVEMENT WIDTHS.
   Pavement widths shall be measured between curb backs. Minimum pavement or surface widths shall be provided according to the code of the city.
(Prior Code, § 7.14)
§ 151.059  STREET SURFACING.
   The streets in the proposed subdivision shall be paved, including curbs and gutters, and street surfacing shall be of concrete or any other suitable surface as recommended by the designated City Engineer and approved by the City Council. Requirements for paving, including curb and gutter, may be waived at the request of the subdivider. Streets in the subdivision shall have a crushed rock or gravel surface which meets the specifications of the city.
(Prior Code, § 7.15)
§ 151.060  CURB AND GUTTER.
   Curb and gutter shall be provided as required by the City Engineer. In areas of notable flash flooding or heavy rain run-off, curbs shall be required on all streets designed for areas where the existing or anticipated residential density of the areas surrounding the proposed subdivision equals or exceeds three dwelling units per net acre. In commercial developments, or where other similar intensive urban uses exist or are anticipated, curbs shall be required. Where curbs exist on abutting properties, their extension shall be required throughout the proposed subdivision. All curb and gutter shall be constructed in conformance with the minimum standards of the city and as approved by the City Engineer.
(Prior Code, § 7.16)
