Edmonds City Council to hear presentation on city’s landslide hazard areas Tuesday night


With the tragic landslide event near Oso, steep slope issues are a real concern to many Edmonds residents — and the Edmonds City Council will discuss the topic at its meeting Tuesday night.

According to the City Council agenda: “Developing property in the North Edmonds Earth Subsidence and Landslide Hazard Area (ESLHA) requires the signing of many “hold-harmless” agreements by developers, engineers, geotechnical scientists, and homeowners who seek to locate homes their. See the map here. This is a required acknowledgement that the risk of a landslide occurring within the ESLHA is greater than other parts of Edmonds.”

The meeting will include a presentation by Steve Wright, P.E., a principal geotechnical engineer with Landau Associates, which has been providing technical support to the City on slope stability issues for many years. Among the topics to be addressed:

– A brief history of the slide activity within the hazard area and measures that have been taken that have helped to reduce the risk for landslides and/or damage resulting from landslide.
– A brief discussion of the similarities and differences between the geologic conditions within the ESLHA vs. those in the vicinity of the recent Oso landslide
– A summary of the fluctuations in the water levels over time that have been observed and as a function of rainfall, and
– A summary of the measures that city staff are taking to monitor conditions within the ESLHA.

The council will begin its meeting with an executive session at 6 p.m. regarding collective bargaining issues, and also to interview candidates for appointment to the Citizen’s Commission on Compensation of Elected Officials and the Planning Board.

At the start of the 7 p.m. regular meeting, the council will hold a swearing-in ceremony for newly promoted Assistant Police Chief Don Anderson.

Also on the agenda:
– Approval of amendment to Alliance for Housing Affordability Interlocal Agreement

– Authorization for the mayor to sign two professional services agreements: One with The Blueline Group for various city-funded capital projects that are scheduled to begin construction in 2014 and 2015, and the other with KPG, P.S. for design of walkway improvements on 15th Street Southwest from Edmonds Way to 8th Avenue South.

– Discussion of Council Vision Planning for 2014, which was started during the Council’s retreat earlier this year.

Following the meeting, the council will convene in executive session regarding pending or potential litigation.
