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 layout of the subdivision with the existing layout or the most advantageous future development of adjacent tracts. Cul-de-sacs of reasonable length will be approved where they are appropriate for the type of development contemplated or where necessitated by topography or other limiting conditions. However, such cul-de-sacs should not exceed 500 feet in length if 15 or more lots abut such 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 60 degrees, in any case.
(E) Wherever there exists, adjacent to the tract to be subdivided, a dedicated or platted and recorded half-width street or alley, the other half-width of such street or alley shall be platted.
(F) Alleys shall be platted in all business districts, to provide safe access to residential lots fronting on highways, major thoroughfares and parkways. Alleys shall be platted in the rear of such lots or service drives provided in front thereof. (Alleys will not be approved in other locations in residential districts, unless required by unusual topography or other exceptional conditions.)
(G) Intersections of more than two streets at one point shall be avoided.
(H) Proposed streets shall be adjusted to the contours of the land so as to produce reasonable gradient and more desirable building sites.
(I) Lands abutting principal thoroughfares should be platted with the view to 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, to minimizing interference with traffic on such trafficways 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 and on the accompanying exhibit, “Development Standards”.
(1) By platting the lots abutting such trafficways at generous depth and by providing vehicular access to them by means of either alleys, service drives in the rear, or frontage access streets next to the thoroughfare connected therewith at infrequent intervals.
(2) By not fronting the lots on the thoroughfares, but on a minor street paralleling the highway at a distance of a generous lot depth, not less than 200 feet. Private driveways in this case would, of course, connect with such minor street.
(3) By means of a street platted more or less parallel with the highway, 600 to 1,000 feet distant therefrom, from which loop streets or culs-de-sac would extend toward the thoroughfare 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 said highway.
