ABSTRACT:
The Washington Geological Surveys Landslide Hazard Program (LHP) was created in early 2016 as a result of legislative funding following the 2014 SR-530 Oso landslide. The LHP team of five geologists has commenced a lidar-based landslide mapping program for the state of Washington. The primary goal is to help Washington communities reduce losses from landslides by mapping landslides, producing susceptibility and exposure maps, and assisting at-risk communities. In March 2016, the LHP collaborated with Pierce County to improve and expand the existing landslide inventory in order to highlight assets at risk to landslide hazards.
Following protocols developed by Oregons Department of Geology and Mineral Industries, the LHP used 1-meter lidar to produce landslide inventory maps, and deep and shallow landslide susceptibility maps. At the onset of this project, the LHP collaborated with county stakeholders including planners, GIS specialists, emergency managers, and engineers to identify areas to map and assets to include in an exposure analysis. This analysis spatially identifies the intersection of public and private assets at risk either due to reactivation of an existing landslide or in areas identified as susceptible to future landslides.
By collaborating, the LHP delivered products that were applicable and informative to users, including the public. The LHP will further assist the county by conducting outreach at public meetings, distributing a homeowners guide to landslides, and by providing spatial and tabular data online at the Washington Geological Surveys Geologic Information Portal. The data created from this project will allow Pierce County to evaluate the threat of landslides to people and property when considering future development and will provide the public with information on how to reduce their risk to landslide hazards. Through public outreach and the publication of maps and data, the LHP provides tools and assistance to inform public and private entities of landslide hazards across Washington State. Our pilot project for Pierce County is nearing completion with future projects to include landslide mapping in the Columbia River Gorge and King County, Washington.
SPEAKER BIOS:
KATE MICKELSON is a landslide hazards geologist at the Washington Geological Surveys Landslide Hazards Program at the Washington Department of Natural Resources (DNR). She has a BS in geology from the University of Colorado and an MS in geology from Portland State University. She spent six years working on landslide inventory, susceptibility, and risk mapping at the Oregon Department of Geology (DOGAMI) before moving to DNR in February, 2016.
STEPHEN SLAUGHTER is the Landslide Hazards Program coordinator at the Washington Geological Survey at the Department of Natural Resources and has worked on landslides for much of his 12 year career at the agency. Stephen has a BS and MS degrees in geology from Western Washington and Central Washington Universities, respectively. He is a member of AEG and GSA and is on the management board of the GSA Environmental and Engineering Geology Division.
