This legislation proposes amendments to Seattle's land use and zoning codes to streamline efficient permitting processes for light rail transit facilities, specifically supporting the West Seattle Link Extension and Ballard Link Extension projects. The amendments address new development standards for light rail facilities, clarify requirements for environmentally critical areas (ECA) exception permits, define tree and vegetation management plan requirements, and update bicycle and micro-mobility device parking requirements at light rail transit facilities. It also establishes an advisory review process by the Seattle Design Commission (SDC) for facility design proposals and clarifies permit processes for efficiency and specificity. The changes are intended to support the timely construction and operation of future light rail extensions and ensure high-quality design, environmental protection, and public access to transit.
