Manning, Oregon

2 Land Tracts in Washington County , Tualatin Watershed

Manning, Oregon, located in Washington County, faces a relatively high risk of natural disasters and climate-related hazards. The area experiences moderate temperature and humidity levels, with a significant amount of precipitation annually. Manning is situated near the Tualatin River and the Willamette River basin, which can contribute to flooding risks during heavy rainfall events. Additionally, the region is part of the Pacific Northwest hydrologic region, which is prone to landslides and mudslides due to its hilly terrain and soil composition.

The proximity of Manning to the Cascade Range and the coastal mountains also poses a potential threat of avalanches and landslides. The region's geological features, including fault lines and volcanic activity from nearby Mount Hood and Mount St. Helens, increase the risk of earthquakes and volcanic eruptions. Historical events, such as the 1700 Cascadia earthquake and the 1980 eruption of Mount St. Helens, serve as reminders of the potential hazards faced by Manning and its surrounding areas. These factors contribute to a relatively high overall hazard risk rating for the region.

While Manning itself may not have a direct coastline, its location in Oregon makes it susceptible to the impacts of coastal storms and tsunamis that can affect nearby coastal communities. The combination of geological features, climate factors, and historical events underscores the importance of comprehensive disaster preparedness and risk mitigation measures for the residents of Manning and the broader Washington County area. It is crucial for local authorities and residents to stay informed about potential hazards and take proactive steps to mitigate risks and enhance community resilience.
