It is a compilation of levee datasets from the following sources: The Oregon Department of Geology and Mineral Industries (2017), The U.S. Army Corps of Engineers (2015), The Lower Columbia River Partnership (2012) and The Oregon Coastal Monitoring Program (2011). A geospatial inventory of levees and levee-like features is an important resource for assessing flood risk, flood mitigation planning and for emergency response during flood events. It also benefits ecological restoration efforts by helping locate levees to remove or breach in order to expand habitat for aquatic species. Until now, the state of Oregon did not have a single comprehensive inventory that maps levees with the high spatial accuracy needed to support these activities. To meet this need, the Oregon Department of Geology and Mineral Industries (DOGAMI) created new levee data and compiled pre-existing levee data into a single geospatial inventory.
