The standards of subsections 23.54.040.I.1.a through 23.54.040.I.1.d may be modified by the Director of Transportation where unusual topography, inability to temporarily stage solid waste containers in a parking lane, or other local conditions present significant challenges for accommodating solid waste container access. J. If the requirements of this Section 23.54.040 cannot be met, the Director, after consultation with the Director of Seattle Public Utilities, may approve alternative arrangements. Such measures may be approved as a Type I decision in relation to any requirement of this Section 23.54.040 , except subsection 23.54.040.I. Alternative staging arrangements may be approved as a Type I decision by the Director after consultation with the Director of Seattle Public Utilities and the Director of Transportation. Approval of alternative arrangements is at the discretion of the Director and does not obligate the Director to grant relief from any requirement or obligate the Director to provide any improvements within a right-of-way. The Director may consider, but is not limited to considering: 1. Whether adequate areas exist on the lot or in the right-of-way for staging or collecting solid waste containers; 2. Whether the solid waste requirements adequately accommodate the needs of a particular development type, such as: a. Affordable housing; b. Small efficiency dwelling units; c. Congregate housing; or d. Development using compaction of solid waste; 3. Whether alternative solid waste arrangements would result in one or more additional dwelling units being constructed; and 4. The effect on the efficiency of collection services such as: a. Minimizing the number of days for collection service; b. Providing safe access to the solid waste collection area; or c. Providing an efficient route between the solid waste storage space and the solid waste collection location. (Ord.
