(A) When rights-of-way for public streets and alleys are needed, they shall be provided in accordance with the standards and requirements described as follows:
(1) Major thoroughfare: 120 feet;
(2) Secondary thoroughfare: 80 feet;
(3) Collector street: 66 feet;
(4) Minor residential street: 55 feet;
(5) Cul-de-sac: 50 foot radius;
(6) Frontage road: 66 feet;
(7) Alley: a minimum width of 20 feet; and
(8) Streets which terminate in a cul-de-sac shall be not longer than 500 feet.
(B) Bike paths and trails, on divisions (A)(l) through (A)(3) above, shall be as follows:
(1) Right-of-way, minimum: ten feet; and
(2) Pavement width: eight feet.
(C) Street jogs with centerline offsets of less than 125 feet shall not be permitted.
(D) Streets shall be laid out so as to intersect as nearly as possible at right angles, and no streets shall intersect any major or secondary thoroughfare or arterial street at less than 75 degrees and no collector or minor street at less than 60 degrees.
(E) Property lines at street intersections shall be rounded with a radius of ten feet, or a greater radius where the Planning and Zoning Commission will deem it, whenever necessary to permit the construction of a curb (having a 15-foot radius) without curtailing the sidewalk at a street corner to less than normal width.
(F) Street names shall be used which will not duplicate or be confused with the names of existing streets. Where a proposed street is to be a continuation of an existing street, the proposed street shall have the name of the existing street. The use of the suffix “street”, “avenue”, “boulevard”, “drive”, “lane”, “place” or “court” shall not be a distinction sufficient to avoid confusion; therefore, duplicates with different suffixes shall not be used.
(G) All streets within the subdivision shall be provided with traffic and street signs by the subdivider in accordance with the Manual of Uniform Traffic-Control Devices.
(H) (1) The road cross-section of all subdivisions shall comply with the following standards.
Average Daily Traffic | Standard Cross-Section |
0 - 150 | 30-foot roadway width, plus curb and gutter |
150 - 300 | 32-foot roadway, plus curb and gutter with sidewalk |
300 - 500 | 34-foot roadway width, plus curb and gutter with sidewalk |
In excess of 500 | 36-foot roadway width, plus curb and gutter with sidewalk |
(2) The above standards are subject to the following conditions and adjustments.
(a) Roll-over curb may be used depending on the necessary application as determined by the Planning and Zoning Commission. The area between the curbs shall be surfaced with concrete or asphalt meeting the standard specifications of the city.
(b) For average daily traffic flows up to 300, the curb and gutter may be omitted at the discretion of the Planning and Zoning Commission, provided the following apply.
1. The drainage pattern as proposed is not dependent on the curb and gutter.
2. All ponding areas, whether on private or public rights-ofway, are constructed at the time the subdivision roads are built.
(c) If, in an area requiring both curb and gutter with sidewalk, the curb and gutter is omitted, the sidewalk shall be retained. The top of the sidewalk shall be set flush with the surface of the adjacent roadway; and
(d) For the purpose of determining section requirements, the highest average daily traffic projection shall govern all streets within the subdivision.
(I) All work in public ways shall meet or exceed city specifications.
