Vulnerability of Major Wastewater Facilities to Flooding from Sea-Level Rise in King County, Washington

King County's Wastewater Treatment Division maintains 77 major facilities, 40 of which are situated adjacent to tidally-influenced water bodies. As effects of climate change continue to grow, the potential for flooding at these facilities as the result of sea-level rise must be assessed and mitigated. The first step in planning for the effects of sea-level rise is to identify which facilities are at risk. This report identifies these facilities and their potential for flooding, considering the effects of both sea-level rise and storm surges, and then recommends the next steps in planning for this change.
