16.20.100  STREETS AND HIGHWAYS – DETERMINATION OF WIDTH.
   Streets and highways not shown on any master street and highway plan, or not affected by proceedings initiated by the City Council or approved by the City Council , upon initiation by other legally constituted governmental bodies, shall not be less width than those set forth under this chapter, except where it can be shown by the subdivider, to the satisfaction of the planning commission and the City Council , that the topography of the small number of lots served and the probable future traffic development are such as to unquestionably justify a narrower width. Increased widths may be required where streets are to serve commercial property or where probable traffic conditions warrant such. Approval or determination of street or highway classification shall be made by the planning commission. (Ord. 89 § 5.3(part), 1955).
