(A)   Streets. 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, 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. Dead-end streets of reasonable length, not to exceed 500 feet unless there are not more than 15 lots abutting such street, will be approved where necessitated by topography or where they are appropriate for the type or development contemplated.
      (3)   Minor streets shall be so designed that their use by through traffic shall be discouraged.
      (4)   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° in any case.
      (5)   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.
      (6)   Alleys shall be platted in all business districts. Alleys will not be approved in other locations including residence districts, unless required by unusual topography or other exceptional conditions.
      (7)   Lands abutting primary arterial streets should 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, the choice depending on the topography and other physical conditions, the character of existing and contemplated developments and other pertinent factors as in dicated below and on the "Development Standards".
         (a)   By platting the lots abutting such trafficways at very 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.
         (b)   By not fronting the lots on the primary arterial but on a paralleling minor street at a distance of a generous lot depth not to be less than 150 feet. Private driveways in this case would, of course, connect with such minor street.
         (c)   By means of a minor street platted more or less parallel with the highway, 600 to 1,000 feet distant therefrom, from which loop streets or dead end streets would extend toward the highway and provide access to the lots backing upon the highway.
         (d)   Any of the means just described shall be required on all federal numbered highways and any marginal access streets shall be incorporated as part of the right-of-way of such highway.
   (B)   Blocks. Blocks shall have sufficient width to provide for two tiers of lots of appropriate depth, except in the case of an interior street paralleling an expressway or primary street.
      (1)   The lengths of blocks shall be such as are appropriate for the locality and the type of development contemplated, but normally shall not exceed 15,000 feet where the average size of lots does not exceed one acre in area.
      (2)   In any block over 900 feet in length the Commission may require that a crosswalk or pedestrian way, not less than 12 feet wide, be provided near the center and entirely across such block.
      (3)   The number of intersecting streets along arterial streets shall be held to a minimum. Wherever practicable blocks along such trafficways shall be not less than 1,000 feet in length.
