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 prevented by topography or other physical conditions, or unless, in the opinion of the Planning Commission, this extension is not necessary or desirable for the coordination of the layout of the subdivision with existing layouts or the most advantageous for future development of adjacent tracts.
   (C)   Proposed streets shall intersect one another as nearly at right angles as topography and other limiting factors of good design permit.
   (D)   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 the street or alley shall be platted.
   (E)   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 a means of safe access thereto.  Alleys will not be approved in other locations in residential areas, unless required by unusual topography or other exceptional conditions.
