The street and highway design shall conform both in width and alignment to any master plan of streets and highways approved by the council and right-of-way for any such street or highway indicated on the master plan shall be dedicated.
The street and highway design shall conform to any proceedings affecting the subdivision which may have been initiated by the council or approved by the council upon initiation by other legally constituted bodies of the city, county or state. If a parcel of land to be subdivided includes a portion of the right-of-way to be acquired for a public freeway or parkway, and the council shall determine the boundaries of the right-of-way to be acquired, the subdivider shall either dedicate or withhold from a subdivision all the area included in such right-of-way.
(Prior code § 23.41)
(a) 
All streets shall, as far as practicable, be in alignment with existing adjacent streets by continuations of the centerlines thereof or by adjustments by curves, and shall be in general conformity with the plans of the planning commission for the most advantageous development of the area in which the subdivision lies.
(b) 
Streets shall be required to intersect one another at an angle as near to a right angle as is practicable in each specific case.
(c) 
Where necessary to give access to or permit a satisfactory future subdivision of adjoining land, streets shall extend to the boundary of the property and the resulting dead-end streets may be approved without a turnaround; provided, that control of access across the dead-end street shall be vested in the city.
In all other cases a turnaround having a minimum radius to the property line of fifty feet shall be required.
(d) 
Whenever a major street or state highway intersects any other street or highway, the property lines at each block corner shall be rounded with a curve having a radius of not less than thirty feet. On all other street intersections, the property line at each block corner shall be rounded with a curve having a radius of not less than fifteen feet. In either case, a greater curve radius may be required if streets intersect at other than right angles.
(e) 
The centerline curve radius on all streets and highways shall conform to accepted engineering standards of design and shall be subject to approval by the city engineer, but shall not be less than five hundred feet for major streets, three hundred feet for secondary streets, and two hundred feet for minor streets.
(f) 
No street or highway shall have a grade of more than twelve percent unless, because of topographical conditions or other exceptional conditions, the city engineer determines that a grade in excess of twelve percent is necessary.
(g) 
Reserve strips controlling the access to public ways or minimizing values for special improvement assessments will not be approved unless the strips are necessary for the protection of the public welfare or of substantial property rights, or both, and in no case unless the control and disposal of the land comprising such strips is placed definitely within the jurisdiction of the city under conditions approved by the planning commission.

Streets and highways not shown on any master street and highway plan, or not affected by proceedings initiated by the council or approved by the council upon initiation by other legally constituted governmental bodies, shall not be of less width than those set forth in this section, except where it can be shown by the subdivider, to the satisfaction of the city council, that the topography of the small number of lots served and the probable future traffic development are such as to unquestionably justify a narrower width. Increased widths may be required where streets are to serve commercial property or where probable traffic conditions warrant such. Approval or determination of street or highway classification shall be made by the planning commission:
(1) 
Major Streets or Highways. Minimum right-of-way, eighty-six feet in commercial areas and seventy-four feet in residential areas. Minimum pavement width, sixty-two feet in residential areas and sixty-two feet in commercial areas, and a three-foot utility easement on lot line on each side of the street right-of-way.
(2) 
Secondary Streets or Highways. Minimum right-of-way, sixty feet. The city council may require up to eighty feet where the street may become a major street at some future date. Minimum pavement width, forty-two feet.
(3) 
Minor Streets. Minimum right-of-way, fifty-two feet. Minimum pavement width, thirty-six feet.
(4) 
Cul-de-sac Streets and Service Roads. Shall not exceed five hundred feet in length from the center of the cul-de-sac to the centerline of street intersections; fifty feet to the minimum radius of the cul-de-sac at the property line, and turnaround radius of forty-four feet to edge of combination curb and gutter.
(5) 
Alleys. Minimum right-of-way, forty feet. Minimum pavement width, twenty-eight feet.

(Prior code § 23.45)
Where a parcel is subdivided into lots of one acre or more, the planning commission may require that the blocks shall be of such size and shape, and be so divided into lots as to provide for the extension and opening of streets and alleys at such intervals as will permit a subsequent division of any parcel into lots of normal size.
