The following general design standards shall govern the approval of any subdivision map:
A. Blocks shall not be longer than one thousand two hundred (1,200) feet between intersecting street lines, except on major streets and thoroughfares, where longer blocks may be required. Frontage on more than one street will not be permitted except on corner lots and reversed corner lots unless necessary because of topographic conditions, and then only upon approval of the Commission and when access rights are released on one street.
B. Improved walkways of not less than ten (10) feet in width, and landscaped as required by the Parks Superintendent, may be required through blocks more than nine hundred (900) feet in length and through other blocks where necessary to provide access to schools, parks, and/or scenic easements.
C. All lots shall front on a dedicated public street or have access to same via a private street or the “stem” of a “flag lot.” Flag lots shall be allowed only when, in the opinion of the Commission, there is no reasonable alternative. The stem of any flag lot shall be a minimum width of fifteen (15) feet; however, if two (2) or more such stems are contiguous for fifty percent (50%) or more of their length, each stem may have a minimum width of ten (10) feet. Not more than four (4) such stems may be permitted contiguously.
