7 Land Tracts in Washington County , Tualatin Watershed

Cornelius, Oregon, located in Washington County, faces relatively high natural disaster and climate risks. The area experiences a moderate climate with high humidity and precipitation levels, making it prone to flooding and landslides. With its proximity to the Tualatin River and the Willamette River, the city is at risk of water-related disasters. Additionally, being part of the Pacific Northwest region, Cornelius is susceptible to seismic activities due to its location near fault lines.

The geological features in the area, such as the nearby Coast Range mountains and the potential for volcanic activity in the region, add to the hazard risk profile of Cornelius. The city's location in a valley surrounded by hills and mountains increases the likelihood of landslides and mudslides during heavy rainfall. Moreover, the coastal proximity of Oregon puts Cornelius at risk of tsunamis in the event of a major earthquake along the Cascadia Subduction Zone.

Historical events in the region, such as the Great Coastal Gale of 2007 and the Vanport flood of 1948, highlight the potential for natural disasters in Cornelius. The combination of climate factors, geological features, and past events underscores the need for comprehensive disaster preparedness and mitigation efforts in the area to safeguard the community against various hazards.
