1109.08 STREET AND BLOCK LAYOUT.

   The street layout of the subdivision shall be in general conformity with a plan for the most advantageous development of adjoining areas and the entire neighborhood.

(a)   Where appropriate to the design, proposed streets shall be continuous and in alignment with existing planned, or platted streets with which they are to connect.

(b)   Proposed streets shall be extended to the boundary lines of the tract to be subdivided, unless, in the opinion of the Commission, such extension is not necessary or desirable for the coordination of the subdivision with the existing layout, or the most advantageous future development of adjacent tracts. Residential dead-end streets (cul-de-sacs) should normally not exceed 600 feet in length. The length of a cul-de-sac shall be determined beginning at the centerline of the nearest intersecting through street.

(c)   Minor streets shall be so designed that their use by through traffic shall be discouraged.

(d)   Proposed streets shall intersect one another as nearly at right angles as topography and other limiting factors of good design permit, but at not less than sixty degrees in any case.

(e)   Alleys should be platted in all business districts when appropriate. To provide safe access to residential lots fronting on a thoroughfare, alleys shall be platted in the rear of such lots or service drives provided in front of such lots. Alleys shall not be approved in other locations in residential districts, unless required by unusual topography or other exceptional conditions.

(f)   Intersections of more than two streets at one point should be avoided.

(g)   Proposed streets shall be adjusted to the contours of the land so as to produce reasonable gradient and more desirable building sites.

(h)   Lands abutting highways or thoroughfares should be platted with the view toward making the lots, if for residential use, desirable for such use by cushioning the impact of heavy traffic on such lots; and with the view, also toward minimizing interference with traffic on such highways as well as the accident hazard. This may be accomplished in several ways, the choice depending on topography and other physical conditions, the character of existing and contemplated developments and other pertinent factors as indicated below.

(1)   By platting the lots abutting such trafficways at generous depth and by providing vehicular access to them by means of either alleys or service drives in the rear, or frontage access roads next to the highway, connected therewith at infrequent intervals.

(2)   By not fronting the lots on the highway or primary thoroughfare but on a minor street paralleling the highway at a distance of a generous lot depth, not to be less than 200 feet. Private driveways in this case would connect with such minor streets.

(3)   By means of a collector street platted more or less parallel with the highway, 600 to 1000 feet distant therefrom, from which loop streets or cul-de-sacs would extend toward the highway and provide access to the lots backing upon the highway.

(4)   One of the means just described shall be required on all federal numbered highways, and any frontage access streets shall be incorporated as part of the right of way of such highway.

(i)   Blocks shall have sufficient width to provide for two tiers of lots of appropriate depth except in the case of an interior street paralleling a limited access highway or an arterial thoroughfare.

(j)   The lengths of blocks shall be such as are appropriate for the locality and the type of development contemplated but shall not exceed 1,320 feet where the average size of lots does not exceed one acre in land.

(k)   In any block over 900 feet in length, the Commission may require that a cross-walk or pedestrian way, not less than twelve feet wide, be provided near the center and entirely across such block.

(l)   The number of intersecting streets along highways and thoroughfares, shall be held to a minimum. Wherever practicable, blocks along such trafficways shall not be less than 1000 feet in length.

(m)   The Planning Commission may determine the number and location of curb cuts and may require deceleration lanes, acceleration lanes, storage lanes and service drives where necessary, and such shall be shown in the construction drawings for the plat of land prior to the plat of land being approved.
