In response to the deadly Oso Landslide of 2014, government agencies have been working diligently to update landslide hazard analysis. Because LiDAR data can map terrain beneath vegetation and tree canopy, it is ideal for revealing potential hazard.
King County has released a new landslide hazard map that utilizes the new technology.
As stated in the Natural Resources and Parks Newsroom,
“Updating these maps with advanced technology makes us better informed and in better position to protect people, property and critical public infrastructure,” said Flood Control District Chair Reagan Dunn. “It will also help us be more strategic in how we work to reduce flood risks.”
The maps are publicly available online, see links below. Additionally, the county is conducting four workshops to educate the public on the information contained in the maps and how it can help improve safety and quality of life in a variety of ways.
Quantum Spatial collected the LiDAR imaging via airborne survey and has years of experience with terrain mapping. Visit our Terrain Analysis page for more details or read past landslide related posts.
