This ordinance updates Seattle's subdivision procedures by amending various sections of Chapter 23.22 of the Seattle Municipal Code. The primary change is delegating the decision-making authority for final plat approvals from the City Council to the Seattle Department of Transportation (SDOT). This change is intended to streamline the process, as the Council's role in final plat approval was deemed ministerial with little discretion, given that preliminary plats (which set most conditions) had already been approved and often infrastructure was already in place. The bill also updates references to standards for subdivision plans and removes references to filing the plan. Additionally, it repeals Subchapter IV of Chapter 23.22, which pertains to 'reserved land' and has never been utilized, potentially conflicting with other regulations. The legislation aims to reduce the time and resources spent by various city departments on approving subdivisions.
