What recent storms did here
Helene's record surge came over the seawalls of Snell Isle in September 2024 and into ground floors of homes that had never flooded before. On Snell Isle the waterfront address and the flood exposure come as a pair. Nothing since has come close: the St. Petersburg tide gauge peaked at 1.43 ft above normal high tide in both 2025 and 2026 so far, on ordinary high tides, versus the 6.31 ft Helene pushed over these seawalls.

How fast can HydroDam install flood barriers in Snell Isle?
Most Snell Isle installs happen within a couple of weeks of the assessment. We fabricate every barrier at our Clearwater shop to your exact openings, then mount the U-channel posts during calm weather. The visit to a Snell Isle home covers measuring, mounting, and a practice deployment. When a storm threatens Pinellas County, you drop the planks in yourself and seal a typical opening in under 10 minutes without a crew.
Can I install flood barriers myself in Snell Isle?
You can deploy them yourself, and the system is designed for that.
