(A) Layout. Adequate streets shall be provided by the subdivider, and the arrangement, character, extent, width, grade and location of each shall conform to the Comprehensive Plan and transportation plan of the city and shall be considered in their relation to existing and planned streets, to topographical conditions and to public safety and convenience, and in their appropriate relationship to the proposed uses of land to be served by the streets. The street layout shall be devised for the most advantageous development of the entire neighborhood. The subdivider shall apply sound access management and traffic principles to street and intersection layouts.
(B) Relation to adjoining street system. Where necessary to the neighborhood pattern, existing streets in adjoining areas shall be continued and shall be at least as wide as the existing streets and in alignment therewith.
(C) Projection. Where adjoining areas are not subdivided, the arrangement of streets in the subdivision shall make provision for the proper projection of streets into the unsubdivided areas.
(D) Jogs. Whenever possible, street jogs with centerline offsets of less than 125 feet shall be avoided.
(E) Half streets or adjacent streets. In the case of collector, minor or marginal access streets, no new half streets shall be platted.
(F) Intersections. Street intersections shall be as nearly at right angles as practicable, giving due regard to terrain and topography.
(G) Dead-end streets. Dead-end streets shall be prohibited, except as short stubs to permit future expansion. In no case shall the length of such street exceed 250 feet. If such street exceeds 150 feet, then a temporary turnaround which meets Fire Department standards shall be provided.
(H) Cul-de-sac.
(1) In general, a cul-de-sac shall not exceed 600 feet in length. Cul-de-sac length shall be measured as the distance from the center of the cul-de-sac to the nearest intersecting street right-of-way line.
(2) In residential areas, the cul-de-sac shall have a minimum right-of-way radius of 50 feet and a minimum driving surface radius of 40 feet.
(I) Location and width of streets shown on the Comprehensive Plan and Transportation Plan. Where a subdivision embraces a street as shown on the Comprehensive Plan and Transportation Plan of the city, this street shall be platted in the location and of the width indicated by these plans.
(J) Minor streets. Minor streets shall be laid out so as to discourage their use by through traffic.
(K) Pavement widths and rights-of-way.
(1) Arterial streets shall have a right-of-way width of at least 80 feet, with a pavement width of at least 45 feet back to back of curbs.
(2) Collector streets shall have a right-of-way of at least 60 feet and a pavement width of at least 37 feet back to back of curbs.
(3) Minor streets shall have a right-of-way of at least 60 feet and a pavement width of at least 30 feet back to back of curb.
(L) Pavement, right-of-way widths. Streets forming part of the boundary of the adjacent subdivision boundary shall have the following pavement widths and rights-of-way widths.
(1) The subdivider shall dedicate a right-of-way of 40 feet in width for new adjacent arterial streets, and two thoroughfare lanes shall be paved.
(2) New adjacent collector and minor streets shall be full width and conform to division (K) above.
(3) Where the proposed subdivision abuts upon an existing street or half street that does not conform to division (K) above, the subdivider shall dedicate right-of-way sufficient to make the full right-of-way width conform to division (K) above, and there shall be paved so much of such right-of-way as to make the full pavement width comply with division (K) above. Before any pavement is laid to widen existing flexible base pavement, the existing pavement shall be cut back two feet to ensure an adequate subbase and pavement joint.
(M) Construction requirements. The minimum standard residential street shall be a 30-foot curb-and-guttered street constructed in accordance with the city’s standards. The City Commission may grant permission to the subdivider to build open ditch, road section streets, conforming to minimum specifications. However, the subdivider must show good and sufficient cause to the City Commission before it will grant permission to build open ditch, road section streets. Additional construction requirements will be promulgated by the City Engineer in accordance herewith and the city’s design standards and details.
(N) Curbs. Curbs shall be installed by the subdivider on both sides of all interior streets, and on the subdivision side of all streets forming part of the boundary of the subdivision, unless the subdivider has permission from the City Commission not to install curbs.
(O) Names. Names of new streets shall not duplicate or cause confusion within the names of existing streets, unless the new streets are a continuation of or in alignment with existing streets, in which case names of existing streets shall be used.
(P) Streetlights. Streetlights shall be installed by the subdivider at all street intersections within the subdivision and at adjacent intersections on the north and east boundaries of the subdivision.
(Q) Street name and traffic control signs. Street name and required traffic control signs shall be installed by the subdivider within or abutting the subdivision.
