Landslide Hazard Zonation REVIEW

The goal of the Landslide Hazard Zonation (LHZ) Project is to create a vastly improved screening tool by better describing and mapping all potentially unstable slope areas in priority watersheds. The purpose is to eliminate any errors of omission in the identification of unstable landforms during both harvest layout and permitting process. In addition to identifying areas of hazard for mass wasting, landforms and hazard classifications are linked to the degree of hazard and sensitivities to land management practices. The LHZ project also provides information useful for appropriate mitigation.

 

Quality Assurance

Prior to public release of the mapping products, they are reviewed at three levels. The first two levels are internal. The third review is by interested and locally informed geoscientists and other interested field users of the products (AKA: external review). Results of the external review are used for two purposes. One, initial results of the evaluation determine the usefulness of the products compared to existing tools. Two, comments received from all levels of the review process are used to improve the products prior to final public release.

GIS data created from this project (landslides and hazard zones) is available on the Forest Practices GIS Spatial Data Sets page, within the rows marked “landslides” and “hazard zones”.

Please note: LHZ draft products remain on this review page until the analyst has responded to review comments and final products are available on the Landslide Hazard Zonation Completed Projects page.
