A variance from any of the requirements specified by this chapter may be granted by the hearing examiner upon the recommendation of the staff and when in the best interest of the public welfare. Such variance may be granted when practical difficulties arise in the design and construction of streets due to topographic geological limitations or other problems inherent or peculiar to the area, or where the council finds that imposition of the required street width would be detrimental to the interest of the neighborhood. [Ord. 2002-10-069 § 23; Ord. 9062 § 1, 1982; Code 1980 at § 11.48.050].
