(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 existing layouts or the most advantageous future development of adjacent tracts. Dead-end streets (courts) of reasonable length will be approved where topography necessitates or where 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 adjoining 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 the rear of all lots to be used for business, and in the rear of residential lots fronting on highways, primary and secondary thoroughfares or parkways, unless service roads are provided in front thereof, as means of safe access thereto.
(b) Blocks shall have sufficient width to provide for two (2) tiers of lots of appropriate depth, unless, in the opinion of the Planning Commission, prevented by exceptional topography or other physical conditions.
(1) The lengths of blocks shall be such as are appropriate, in the opinion of the Planning Commission, for the locality and the type of development contemplated, but shall not exceed one thousand eight hundred feet (1,800 ft.) where the average size of lots does not exceed two (2) acres in area.
(2) In any block over nine hundred feet (900 ft.) in length, the Planning Commission may require that a crosswalk or pedestrian way, not less than ten feet (10 ft.) wide, shall be provided near the center and entirely across such block.
