16.12.040: STREET REQUIREMENTS:
   A.   The arrangement, character, extent, width, grade and location of all streets shall conform to the comprehensive plan and shall be considered in their relation to existing and planned streets, topographic conditions, public convenience and safety, and in their appropriate relation to the proposed uses of the land served.
   B.   Where a subdivision abuts or contains an existing or proposed arterial street, the city council may require frontage streets, reverse frontage streets or similar treatment for the purpose of creating desirable neighborhood character and enhancing the movement of traffic.
   C.   The city council may require a street along a railroad right of way suitable for the appropriate use of the intervening land.
   D.   There shall be provided rights of way of such width in no case to be less than those defined in the comprehensive plan for the city; provided, however, that the width of said rights of way shall in no case be less than the following:
      1.   Regional arterial route: One hundred feet (100') and up.
      2.   Collector street: Seventy feet (70') to ninety feet (90').
      3.   Local street: Sixty feet (60'); a local street right-of-way may be reduced to fifty feet (50') upon a special exception by the Council.
   E.   Street grades shall be such as to provide for the safe movement of traffic in all weather and for adequate drainage of streets. Street grades, whenever feasible, shall be not less than three-tenths percent (0.3%) and not more than fifteen percent (15%).
   F.   In general, partial street dedications shall not be permitted; provided, however, that the council may accept a partial street dedication when such street forms the boundary of the property being subdivided and, in addition, is shown on the comprehensive plan, or is designated by the city council as an arterial or collector street, or is otherwise officially designated as of major importance as a present or future trafficway, or when such other conditions or restrictions exist or are imposed by the city council so that the eventual completion of such street to its full required right of way is assured. When a dedicated partial street exists adjacent to the property to be subdivided, the other portion may be platted within such subdivision.
   G.   A street ending in a cul-de-sac may be permitted; provided, that the maximum length for such a street shall be four hundred feet (400') as measured from the entrance to the center of one turnaround. All turnarounds shall have a minimum radius of fifty feet (50') at the property line and not less than forty five feet (45') at the curbline.
   H.   Dead end streets shall not be permitted with the exception that such streets terminating at the boundary of a subdivision may be approved when such a street and its extension is shown on the comprehensive plan or when, in the opinion of the city council, the future extension of such a street is feasible and necessary to the proper development of the city street pattern. A temporary cul-de-sac shall be constructed at the end of a dead end street.
   I.   The maximum length of a loop street shall be one thousand feet (1,000') and a loop street over this length, though otherwise meeting the definition of a loop street, shall be required to conform to the standards of a local street in its subdivision type; provided, however, that a loop street of up to one thousand two hundred feet (1,200') in length containing frontage of no more than twenty four (24) building lots may be permitted.
   J.   Streets shall be designed and laid out in order to intersect as nearly as possible at right angles, and no street shall intersect any other street at less than seventy degrees (70o).
   K.   Where any street deflects an angle of ten degrees (10o) or more, a connecting curve having a minimum radius of three hundred feet (300') for arterial and collector streets and one hundred fifty feet (150') for local streets may be required by city council.
   L.   Proposed streets which are a continuation of an existing street shall be given the same name as the existing street. New streets which are not a continuation of an existing street shall not be given names that are the same or similar, either in spelling or pronunciation, to existing streets within the city or in the impact area. The developer shall obtain all street names within the proposed subdivision from the planning and zoning commission before submitting same to the city council for final approval.
   M.   Street trees where provided shall be of the variety, size and location approved by the council, shall not create a sight restriction and comply with title 12 of this code. (Ord. 1482, 2020: Ord. 1219 § 1, 2002: Ord. 905, 1980: prior code § 11-15-6(D))
