The following standards shall apply to all streets in a subdivision:
(A) All street grades shall be established or approved by the City Engineer to ensure continuous drainage from one area to another.
(B) The minimum acceptable street right-of-way shall be 80 feet for arterial streets, 66 feet for collector streets, 60 feet for local streets, 50 feet for cul-de-sac streets and 40 feet for frontage streets.
(C) Cul-de-sac streets shall not be more than 600 feet in length, measured from the centerline of the intersection of the cross street to the centerline of the cul-de-sac, except where the Planning Commission has approved additional length due to property limitations, with a minimum 55-foot turnaround radius shall be provided at the closed end with either an off-set or symmetric circular turnaround having an outside pavement diameter of at least 100 feet. All lots that are adjacent to the radius of a cul-de-sac shall have a minimum 40-foot front lot line measured along the arc of the street right-of-way.
(D) The arrangement of major streets shall conform to the comprehensive plan as nearly as possible.
(E) Where a proposed subdivision is adjacent to or contains an existing major or primary thoroughfare, provision shall be made for a frontage road approximately parallel and adjacent to the right-of-way line, or lots shall back up to the major street and have access only to the local street.
(F) Half streets shall be prohibited except where essential to the reasonable development of the subdivision in conformity with the other requirements of this chapter, or where it is found to be practical to require the dedication of the other half when adjoining property is subdivided.
(G) Under normal conditions streets shall be laid out so as to intersect as nearly as possible at right angles. More than 4 approaches to any intersection shall be prohibited.
(H) Street jogs at intersections with centerline offsets of less than 150 feet shall be prohibited.
(I) There shall be no private streets platted in any subdivision. Every subdivided lot shall be served from a publicly-dedicated street.
(J) Where a proposed subdivision fronts on a state or federal highway or a major thoroughfare, intersections onto the highway or thoroughfare shall be determined by the City Engineer and State of Nebraska.
(K) Where a proposed subdivision fronts on an arterial, intersections onto the arterial shall be determined by the City Engineer.
(L) Curb cuts shall be prohibited within 25 feet of an intersection corner property line.
(M) In general, intersection streets determining block lengths shall be provided at such intervals as to serve cross traffic adequately and to meet existing or future streets. When no existing plats control, the minimum block length shall be 600 feet.
(N) Local streets shall be designed to benefit from the topography, to discourage through traffic and to provide the minimum amount of streets necessary for safe access to adjacent properties. The reasonable and intelligent use of curvilinear and cul-de-sac streets is encouraged wherever possible.
(O) Alleys may be required in all commercial and industrial districts, except that the Planning Commission may waive this requirement where the commercial or industrial district is designed as a comprehensive unit and adequate provision for loading space is a part of the overall development plan.
