1228.03  STREETS.
   (a)   A street layout shall provide access to all lots and parcels of land within a subdivision. Street jogs at intersections of less than 125 feet shall be avoided.
   (b)   Street terminations in a cul-de-sac shall not exceed 700 feet in length, unless a greater length is necessitated by site topography.
   (c)   Local or neighborhood streets shall be designed by pattern and layout so as to discourage through traffic.
   (d)   Proposed streets, where appropriate, shall be extended to the boundary of the tract to be subdivided so as to provide for normal circulation of traffic with adjacent existing or future subdivisions or developed areas.
   (e)   Wherever there exists a dedicated or platted portion of a street or alley within the proposed subdivision, the street or alley shall be platted to the prescribed width within the proposed subdivision.
   (f)   Widths of major highways, primary and secondary thoroughfares and collector and local street rights-of-way shall conform to the widths specified in Plate 1. These widths may be increased, decreased or varied in unusual circumstances by the Planning Commission.

1.   Additional right-of-way may be required by the Planning Commission.
2.   Pavement width shall be measured from back of curb to back of curb. The standards as shown in the cross-section of Bakersfield Subdivision, a copy of which is attached to original Ordinance 23-81, passed March 9, 1981, and made a part of this section by reference, shall be used in the construction of local access streets, and curbs shall be of a four-inch roll type as shown in the cross-section.
         (Ord. 9-76.  Passed 9-9-76; Ord. 23-81.  Passed 3-9-81.)
 
   (g)   The minimum right-of-way of local streets, including marginal access streets and cul-de-sacs, shall be fifty feet. All cul-de-sacs shall terminate in a circular right-of-way with a minimum diameter of 100 feet.
   (h)   Where a street having two or more lots fronting thereon ends at a subdivision line for future extension, it shall be provided with a temporary paved turn-around until such extension is completed. The size of the turn- around shall be not less than sixty feet in diameter.
   (i)   A subdivision that includes or borders on an existing street that does not conform to the required width shall dedicate additional width along either or both sides of the street. Not more than half of the required right-of-way shall be taken from either side of the street.
   (j)   All streets shall be constructed in accordance with the Municipal street construction specifications, as set forth in Chapter 1022 of the Streets, Utilities and Public Services Code.
   (k)   A street intersection shall be at a ninety degree angle of intersection.
   (l)   At street intersections, the property line corners shall be rounded by arcs with radii of not less than twenty feet.
   (m)   The intersection of more than two streets at one point is not permitted.
   (n)   Where parkways or special types of streets are involved, the Planning Commission may apply special standards to be followed in the design of such parkways or streets.
   (o)   Whenever the subdivision contains or is adjacent to a railroad right-of-way, or a highway designated as a limited access highway by the appropriate authorities, provision shall be made for either a marginal access street or a parallel street at a distance adequate to permit the use of adjoining land.
   (p)   Horizontal visibility on curved streets and vertical visibility on all streets shall be maintained along centerlines as follows:
      (1)   Major highways and thoroughfares   500 feet;
      (2)   Collector streets and parkways   300 feet; and
      (3)   Residential access streets      100 feet.
   Where topographic or other conditions warrant it, the Commission may, with the approval of the Municipal Engineer, reduce these requirements.
 
   (q)   Horizontal curvature measured along the centerline shall have a minimum radius as follows:
      (1)   Major highways and thoroughfares   500 feet;
      (2)   Collector streets and parkways   300 feet; and
      (3)   Residential access streets      150 feet.
   Where topographic or other conditions warrant it, the Commission may, with the approval of the Municipal Engineer, reduce these requirements.
   (r)   All changes in grades shall be connected by vertical curves of sufficient radii to provide smooth transitions and required site distances.
   (s)   Between reverse curves on major highways and thoroughfares, there shall be a tangent of not less than 100 feet. On collector and local or neighborhood streets, such tangent shall be not less than forty feet. In hillside areas, there shall be a tangent of not less than fifty feet between reverse curves on major highways and arterial streets. On collector streets in hillside areas, such tangents shall be not less than twenty feet.
   (t)   The maximum gradient for a street shall be six percent, unless a greater gradient is approved by the Municipal Engineer and the Commission.
   (u)   The minimum grade of a street gutter shall be five-tenths of one percent.
   (v)   A new street may be called an avenue, circle, court, drive, place, street or way, but it shall not be called a road or highway. Street names shall be sufficiently different in sound and spelling from other street names in the Municipality and abutting townships.
   (w)   Alleys are not permitted in residential areas, but shall be included in commercial and industrial areas, where needed, for loading and unloading or access purposes where required. Alley rights-of-way shall be at least twenty feet in width and shall be fully paved, except for curbs and gutters, and shall allow for drainage toward the center and adjoining streets with catch facilities.
   (x)   Dead-end alleys shall be avoided, but if unavoidable, shall be provided with adequate turn-around facilities at the dead end, as determined by the Commission.
   (y)   Streets shall be arranged such that adjacent building sites are above the grade of the streets wherever possible.
   (z)   All proposed streets shall conform to the Land Use Plan.
