The following requirements are applicable to all subdivisions within the jurisdiction of the commission:
(A) The street layout shall be in general conformity with a plan for the most advantageous development of adjoining areas and the entire neighborhood.
(B) All lots within the subdivision must be served by public streets.
(C) Where appropriate to the design, streets shall be established to avoid jogs at intersections and to promote continuity of local streets and those of higher classification.
(D) Streets shall be established to take advantage of the contour of the land so as to produce usable lots, cause a minimum of cutting and filling, and to produce streets with reasonable grades, as defined in section 6-4-11 of this chapter.
(E) Certain proposed streets, where appropriate, shall be extended to the boundary line of the tract to provide for adequate circulation of traffic within the vicinity.
(F) Streets shall intersect other streets as near to a ninety degree (90°) angle as topography and other factors permit. Intersections of streets with arterial or collector streets shall be limited to a minimum angle of seventy degrees (70°) unless specifically approved by the commission.
(G) Whenever there exists a dedicated or platted portion of a street or alley adjacent to the proposed subdivision which conforms to the thoroughfare plan, the remainder of the street or alley shall be platted to the prescribed width within the proposed subdivision.
(H) Street and right of way widths shall conform to those indicated in the thoroughfare plan. Where such widths are not prescribed therein, the widths shall not be less than the minimums stated in section 6-4-9 of this chapter.
(I) Alleys shall be platted: 1) in the rear of all lots to be used for business; 2) in the rear of residential lots fronting on arterial or collector streets as a means of safe access thereto. Alleys will not be approved in other locations in residential areas, unless required by unusual topography or other exceptional conditions.
(J) Lands abutting arterial or collector streets shall be platted with the view of making the lots, if for residential use, desirable for such use by cushioning the impact of heavy traffic on such trafficways; and with the view also of minimizing interference with traffic on such trafficways as well as the accident hazard. This may be accomplished in several ways:
1. By platting the lots abutting such trafficways at generous depth, with setbacks or front yards at least ten feet (10') greater or deeper than otherwise required; and providing vehicular access to them by means of either alleys or service drives in the rear, or frontage access roads next to the trafficway, connected therewith at infrequent intervals;
2. By a collector street platted more or less parallel with the highway or thoroughfare, six hundred (600) to one thousand feet (1,000') distant therefrom, from which loop streets or dead end streets would extend toward the highway, the ends of which provide access to the lots abutting the highway to their rear.
(K) Dead end streets are often desirable and will be approved if limited to six hundred sixty feet (660') long.
(L) Closed subdivisions (with 1 exit) shall be limited to one hundred (100) dwelling units.
(M) Blocks shall have sufficient width to provide for two (2) tiers of lots of appropriate depth, unless, in the opinion of the commission, prevented by unusual topography or other physical conditions.
(N) The length of blocks shall be such as are appropriate, in the opinion of the commission, for the locality and type development contemplated, but shall not exceed one thousand feet (1,000') when the average lot size does not exceed an acre in area.
(O) In any block over eight hundred feet (800') in length, the commission shall require that a crosswalk or pedestrianway, not less than ten feet (10') wide, be provided near the center and entirely across the block. Within this ten foot (10') right of way shall be constructed a concrete sidewalk five feet (5') in width.
(P) The number of intersecting streets along arterial and collector streets shall be held to a minimum, and where practicable, blocks along such trafficways shall not be less than eight hundred feet (800') in length. (Ord. 365, 11-3-1970; amd. 1979 Code)
