Flooding in Longview WHAT YOU NEED TO KNOW

Longview, Washington, sits at the meeting point of the Columbia and Cowlitz Rivers—a location that brings natural beauty, but also significant flood risk. The city’s flat, low-lying terrain and proximity to waterways make it vulnerable to flooding from heavy rainfall, river overflow, and even dam-related events. Flood events in recent years have shown how quickly conditions can change, especially during the winter months. Such events are bound to increase over time thanks to changing weather conditions and urbanization, with studies showing that over 12,500 or 87% of all Longview homes are at risk of flooding as of today. That’s why private flood insurance in Longview, WA is an essential part of protecting your home, your belongings, and your peace of mind.

Flood Zones in Longview

Longview includes a mix of FEMA-designated flood zones. Properties along the Columbia and Cowlitz Rivers, as well as areas near streams and creeks, may fall into high-risk flood zones (Zone AE or VE). If your property is located in one of these zones and you have a federally backed mortgage, flood insurance is typically required. But don’t let a “low-risk” designation give you false confidence. Zone X areas still experience floods due to stormwater runoff, blocked drainage, or extended periods of rainfall. In fact, data from FEMA shows that nearly 40% of all flood claims come from homes outside high-risk areas.
