Flooding in California can take several forms, from atmospheric-river-driven rainfall and overflowing waterways to coastal flooding, flash floods, localized drainage problems and post-wildfire debris flows.

Flood walls can help protect homes, businesses, facilities and infrastructure from rising water, but choosing the right system requires more than comparing product heights. The best flood barrier should match the expected flood conditions, the area being protected, the site surface and the resources available for deployment.

Garrison Flood Control is proud to announce that it has been named to the 2026 Inc. 5000, ranking No. 63 overall in the United States, No. 2 among manufacturing companies nationwide, and No. 8 among companies in Florida.

A luxury waterfront residence on Di Lido Island in Miami Beach, Florida required a comprehensive flood mitigation solution for multiple vulnerable openings throughout the property. Located in a high-risk flood zone (FEMA Flood Zone AE), the homeowner requested a robust, integrated system to protect the perimeter, access points, and high-value electrical equipment. The solution, the USA-made Hammerhead® Aluminum Flood-Log System. Chosen for its ability to withstand heavy flood loads, quick deployment before a storm, advanced engineering and aesthetically unobtrusive for daily living.

Microburst storms can develop quickly, affect a relatively small area, and cause serious damage within minutes. While microbursts are best known for destructive straight-line winds, wet microbursts can also produce intense rainfall that overwhelms drainage systems and creates sudden, localized flooding.

Garrison Flood Control collaborated with Pinellas County Officials to host a live hands-on flood product and preparedness demonstration on July 22, 2026. This approach allowed key-county personnel tasked with emergency preparedness and operational maintenance and response to directly assess the wide variety of flood control systems and water diversion solutions directly available for their needs through Garrison Flood Control.

If you've seen the headlines, you might think Florida just made it permit-free to protect your home from flooding. Under HB 803, homeowners and their contractors can now install temporary hurricane and flood protection walls or barriers without pulling a building permit.

The best residential garage flood wall depends on the opening, expected water depth, deployment time, storage space, acceptable permanent hardware, and whether water should be stopped at the garage door or diverted farther away.
