Sea Level Rise Planning

Working together to develop a Sea Level Rise Response Plan

The City of Olympia is leading a joint planning effort with the Port of Olympia and LOTT to develop a sea level rise response plan. This work builds on previous planning efforts related to climate change and sea level rise. Working together will ensure a coordinated strategy for protecting downtown Olympia and the Port peninsula from the impacts of sea level rise. The plan will identify needed actions, estimated costs, implementation schedules, and responsibilities.

LOTT’s Budd Inlet Treatment Plant is located in an area susceptible to flooding from sea level rise (SLR). This puts plant structures at risk from inundation and plant processes at risk from increased peak flows due to the combined stormwater/sewer piping system in downtown Olympia. LOTT completed a vulnerability assessment for the Budd Inlet Treatment Plant in 2014 which focused primarily on risks to the physical structures at the plant site. The current planning effort will evaluate options for protecting downtown Olympia, including the plant site, and will provide a better understanding of actions needed to mitigate risks from the combined storm/sewer system.
