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.
- West Longview (ZIP: 98632) – prone to street flooding and drainage issues during heavy rain.
- Downtown and Highlands areas – located near the Cowlitz River and vulnerable during regional flood events
- Industrial and port-adjacent zones – exposed to flooding due to proximity to both rivers and limited elevation.

Common causes of flooding in Longview
Seattle’s flooding isn’t just about being near a river. Some of the most damaging floods happen in unexpected places due to:
Prolonged rainfall – weeks of steady rain can saturate the ground and flood streets and homes.
Urban runoff – water flows quickly across pavement and rooftops, increasing flood severity in built-up areas.
Blocked or undersized drains – debris, leaves, or ice can clog drains and trigger flash floods.
Dam-related threats – areas downstream from Castle Lake or other natural barriers face additional risk if those structures fail.
Tidal surges and sea level rise – king tides and rising sea levels threaten coastal areas.
Even if your home hasn’t flooded before, weather patterns and urban growth have increased the odds, making private flood insurance in Longview, WA a smart investment.
