      **   The Planning Commission may permit a pavement of not less than twenty feet in width for minor streets and roads where the subdivision or area is located outside the corporate limits and where conditions A. and B. exist, and inside the corporate limits where condition C. exists:
         A.   The tract is not abutting and is not within one and one-half miles from any State highway, and
         B.   The tract does not have and is not within one mile from any area now having municipal water, sewer or waste collection service.
         C.   The topography is such that it would not be feasible from an engineering standpoint to build a street of wider width.  In such instances parking would be prohibited on both sides of the street and a note indicating that no parking shall be permitted shall be placed on the recorded subdivision plat.  The subdivision that falls within this determination shall meet all other requirements of these Regulations including right of way, vertical grade and dimensions of cul-de-sacs.  A guard rail shall be required where the incline of the slope exceeds 3:1 and where the height of the embankment is three feet or greater.
