Description

In 2010, Olympia City Council directed staff to investigate the implications of 50-inches of sea rise to our downtown and to develop a progressive strategy of appropriate responses. Over the past three years, City technical staff and coastal engineers have developed near and long-term priorities and implementation actions. The new analysis links a comprehensive marine simulation of Budd Inlet with land elevations and uses, stormwater and wastewater infrastructure, major precipitation events and sea level rise. The analysis provides a tangible and easily visualized approach for understanding and quantifying the implications of sea rise in downtown Olympia. The simulations identify how sea rise flooding is likely to occur in specific downtown locations (e.g, stormwater pipe backflow, pipe capacity limits, overland flow). They quantify potential volumes and durations of flood waters at specific locations under various marine, precipitation, and sea rise scenarios. In early 2013, we provided our community with a strategy of appropriate responses and their timely implementation. The evolving analysis in concert with an unusually high tide in late 2012 highlighted the current flood vulnerability of our downtown regardless of potential sea rise. With specific vulnerabilities identified and quantified, work is underway to improve near-term flood management responses. Andy Haub, P.E.

Responding to Sea Level Rise Risks in a Vulnerable Community

Room 6E

In 2010, Olympia City Council directed staff to investigate the implications of 50-inches of sea rise to our downtown and to develop a progressive strategy of appropriate responses.
