Lake Sammaish Flood Petition Feburary 2020

Lake Samm shoreline neighbors,


The recent extreme high water on the lake is only partly Mother Nature’s fault; it is also a consequence of the failure of a government flood control project and ongoing government inaction.  Measures can be taken to address this problem.


Interested in more background about the lake and its drainage – to read the more detailed background, click here.


The petition itself is online.  This is the document we will send to the agencies listed below.  To review the petition, click here.


But in any case, please complete the on-line survey by clicking here

This is where you can approve the petition and provide some additional information and comments.


Responses will be compiled an submitted to The Corps of Engineers, King County, and the cities of Bellevue, Redmond, Sammamish, and Issaquah.  Something can be done, but it won’t happen unless we bring pressure to bear on those who can take action.

Thank you,

Your Lake Sammamish neighbors

Large Wood Debris in Rivers Public Meetings | June 12 and June 13

Posted by admin on May 10th, 2018

King County’s flood risk reduction and habitat restoration projects sometimes require the placement of large wood into rivers and streams. Large wood can slow down a river, create pools and hiding places for young salmon, and bolster levees or revetments that protect people and infrastructure from flood risks. If you would like to learn about King County projects that involve the placement of large wood, please join us for a conversation about our current projects.
