Minimum standards and specifications for all streets and alleys in the city are to be kept on file in the office of the city engineer and may be changed from time to time in the interest of safety and construction. The width for all streets shall be determined by the Governing Body, which may consider recommendations of the planning commission, except that all streets shall have a minimum width of twenty-eight feet; provided, however, that whenever the Governing Body finds that the strict application of this section will constitute unnecessary hardships upon the abutting property owners, or that the terrain or physical features of the property affected necessitate a narrower width, the Governing Body may authorize a street of less than twenty-eight feet. (Ord. 601 § 1, 1977; Prior Code § 9-301.)
