The following street criteria shall be adhered to when developing any subdivision plat:
(A) The arrangement, character, extent, width, grade and location of all streets shall conform to the general plan for the city and shall be considered in their relation to existing and planned streets, to topographical conditions, to public convenience and safety, and their appropriate relation to the proposed uses of the land to be served by such streets.
(B) Where such is not shown in the general plan for the city, the arrangement of streets in the subdivision shall either:
(1) Provide for the continuation or appropriate projection of existing principal streets in the surrounding area; or
(2) Conform to a plan for the neighborhood approved or adopted by the Commission to meet a particular situation where topographical or other conditions made continuance or conformance to existing streets impracticable.
(C) Minor streets shall be so laid out that their use by through traffic will be discouraged.
(D) Where a subdivision abuts or contains an existing or proposed arterial street, the Commission may require marginal access streets, reverse frontage with screen planting contained in a non-access reservation along the rear property line, deep lots with rear service alleys, or such other treatment as may be necessary for adequate protection of residential properties and to afford separation of through and local traffic.
(E) Where a subdivision borders on or contains a railroad right-of-way, the Commission may require a street approximately parallel to and on each side of such right of-way, at a distance suitable for the appropriate use of the intervening land, as for park purposes in residential districts, or for commercial or industrial purposes in appropriate districts. Such distances shall also be determined with due regard for the requirements of approach grades and future grade separations.
(F) Reserve strips controlling access to streets shall be prohibited except where their control is definitely placed in the city under conditions approved by the Commission.
(G) Street intersections with centerline offsets of less than 125 feet shall be avoided.
(H) A tangent at least 100 feet long shall be introduced between reverse curves on arterial and collector streets.
(I) Streets shall be laid out so as to intersect as nearly as possible at right angles.
(J) Fire hydrants shall be so located that no residence or commercial building is more than 500 feet from a fire hydrant.
(K) Property lines at street intersections shall be rounded with a radius of 20 feet or of a greater radius where the Commission may deem it necessary.
(L) Street right-of-way widths shall be as shown in the general plan for the city and where not shown therein shall be not less than as follows:
(1) Major thoroughfares, street right-of-way width of 80 feet.
(2) Collector, street right-of-way width of 60 feet.
(3) All others, street right-of-way width of 50 feet.
(M) Dead-end streets, designed to be so permanently, shall not be longer than 500 feet and shall be provided at the closed end with a turn-around having an outside roadway diameter of at least 80 feet and a street property line diameter of at least 100 feet. In cases where this will work a hardship on a property owner developer, it may be extended to a longer length street.
(N) Street grades shall be established with due regard being had for topography, contemplated land uses, and the existing city drainage plan and facilities in the area surrounding the land to be subdivided, provided that the minimum street grade shall be five-tenths of one percent. No land shall be rejected for subdivision purposes for failure to provide for greater street grade than that contained in this section.
(O) The flood design section for roadways shall be taken from back of curb to back of curb, provided that in no case shall the height of curbs for subdivision be more than eight inches. The run-off factor used in design of storm sewers shall be a minimum of Talbots and Rational Formula.
(P) Half streets shall be prohibited, except where essential to the reasonable development of the subdivision and these regulations; and where the Commission finds it will be practicable to require the dedication of the other half when the adjoining property is subdivided. Wherever a half street is adjacent to a tract to be subdivided, the other half of the street shall be platted within such tract.
(Q) No street names shall be used which will duplicate or be confused with the names of existing streets.
