Today I visited with the U.S. Geological Survey and the University of Washington on their efforts to provide the Northwest with science you, the homeowner, can use. (Here's my story that aired on KING 5.) Ever wondered if your house might slide into Puget Sound? By visiting this link, you can now see just how vulnerable your home might be to a landslide. Through a series of maps you can get down to the neighborhood, even block-by-block level to see just how near you are to a "yellow" or "red" zone.... While this information pertains to landslide hazards on nearly every slope in Seattle, it is becoming increasingly possible to pinpoint your risks to natural disaster. These days it can seem there's too much information available, while at the same time there's not enough information that's relevent to one's specific situation. Government websites are often so thorough they can be difficult to navigate, but try it --it might be worth your while to know where you stand. 1 Comments |
The Seattle Composite Geologic Map that shows landslide risk and gives the definitions in a pop up window... at this address:

Gives pop up definitions that aren't coded to the colors on the map.
This map is from the page at:

I live in North City and the map doesn't extend that far. Yet, a project developed in my neighborhood to underground the wiring infrastructure didn't take in to account landslide hazard. I know, because when I asked the planning consultant about this, he scoffed at the suggestion even though it was a site at the top of a cliff. He said they would have to drill core holes; just like the ones that were done methodically in Seattle, which were the basis of the map findings! It would be too intensive and there was no risk evident in the area despite the fact that they are repeatedly repaving 25th NE because of sliding, which runs just below the project ridgeline.
