(A) 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.
(1) 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.
(2) Proposed streets shall be extended to the boundary lines of the tract to be subdivided, unless prevented by topography or other physical conditions or unless, in the opinion of the Planning 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. Dead-end streets of reasonable length, normally not over 600 feet, will be approved where necessitated by topography or where, in the opinion of the Planning Commission, they are appropriate for the type of development contemplated.
(3) Proposed streets shall intersect one another as nearly at right angles as topography and other limiting factors of good design permit.
(4) 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.
(5) Alleys shall be platted in all commercial and industrial areas if no other provisions are made for adequate access to parking and loading spaces. To provide safe access to residential lots fronting on thoroughfares, major streets and highways, 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 residence districts, unless required by unusual topography or other exceptional conditions.
(6) Temporary dead-end streets shall be permitted where necessitated by the design of the subdivision, provided, that temporary turn-arounds shall be constructed where lots are fronting on such temporary dead-end streets. The extra width therefor shall be the same as required for permanent turn- arounds, provided that such extra width in excess of the street right-of-way shall be vacated upon extension of the temporary street.
(B) Blocks shall have sufficient width to provide for two tiers of lots of appropriate depth.
(1) The lengths of blocks shall be such as, in the opinion of the Planning Commission, are appropriate for the locality and the type of development contemplated, but shall not exceed 1,800 feet where the average size of lots does not exceed two acres in area.
(2) In any block over 900 feet in length, the Planning Commission may require that a crosswalk or pedestrian way, not less than ten feet wide, be provided near the center and entirely across such block.
(3) The number of intersecting streets along the highways, thoroughfares and parkways shall be held to a minimum. Wherever practicable, blocks along such traffic ways shall be not less than 1,200 feet in length.
