PASS-A-GRILLE FLOOD BARRIERS FOR HISTORIC AND GULF-FRONT HOMES. CUSTOM FABRICATED. LOCALLY INSTALLED.
Pass-a-Grille sits at the southern tip of St. Pete Beach, a narrow stretch of barrier island with the Gulf on one side and Pass-a-Grille Channel and Boca Ciega Bay on the other. When Helene hit in 2024, around five feet of storm surge swept across the island, piling sand and water through the historic district and into homes. Dam It Defense flood barriers are custom-measured, engineered, and installed by our local team.
Hurricane Season 2026 begins June 1. Don’t wait until a Storm Watch is issued.

2.5X Strength & Seal
Aerospace Grade aluminum that is 2.5X the thickness and density of most competing products; allowing it to withstand a jaw dropping 40,000+ PSI. Thicker, larger, and denser 2-phase age-resistant EPDM gaskets for maximum seal and longevity.
Dam It Difference

View System Specifications
Not all flood barriers are built the same. Our aluminum flood barrier systems use aerospace-grade aluminum cross sections, reinforced channel depth, and dual-phase EPDM compression gaskets engineered to a higher standard than most competing flood protection systems on the market on the Pinellas beaches and across Tampa Bay.
What makes Pass-a-Grille one of Pinellas County’s most surge-exposed barrier-island neighborhoods.
Pass-a-Grille is the historic southern tip of St. Pete Beach, a narrow barrier island with the Gulf of Mexico on one side and Pass-a-Grille Channel and Boca Ciega Bay on the other. With water on both sides and very little elevation, surge has nowhere to go but into the streets and homes. During Hurricane Helene in 2024, around five feet of storm surge swept across St. Pete Beach, leaving sand piles and debris through the historic Eighth Avenue district and flooding ground floors across the neighborhood. The Pinellas County Sheriff described the beaches afterward as a war zone. Pass-a-Grille is a Zone A mandatory evacuation area, with Gulf-front parcels in FEMA Zone VE and the rest in Zone AE.
Surge from both sides
At the narrow south end of the island, water comes from the Gulf and from Pass-a-Grille Channel and Boca Ciega Bay at once. During Helene, surge crossed the island from both directions, leaving homes with almost nowhere for the water to drain.
Repeat storm history
Pass-a-Grille and St. Pete Beach took a one-two punch in 2024, hit by Hurricane Helene and then Hurricane Milton weeks later. Hotels and homes across the island flooded, and many are still rebuilding. This is not a once-in-a-generation risk.
Historic, ground-level homes
Pass-a-Grille’s older, single-story and ground-level historic homes sit close to grade, which leaves them especially exposed to surge and to the costly, slow recovery that follows.
FEMA Zone VE and AE designation
Gulf-front Pass-a-Grille parcels are designated FEMA Zone VE, a Coastal High Hazard Area where wave action is factored on top of surge. The rest of the neighborhood falls in Zone AE. Both require flood insurance for most mortgaged properties.
Custom flood barriers and layered protection for your barrier-island property.
Pass-a-Grille properties face surge from the Gulf and the bay at once. We help you protect perimeter openings first, then address additional vulnerabilities with one coordinated team.

Common Pass-a-Grille flood barrier questions.
Is Pass-a-Grille in a FEMA flood zone?
Yes. Pass-a-Grille is a barrier-island neighborhood in a Zone A mandatory evacuation area. Gulf-front parcels are designated FEMA Zone VE, the highest-risk Coastal High Hazard Area, and the rest is in Zone AE. Both require flood insurance for most mortgaged properties given surge exposure from the Gulf and Pass-a-Grille Channel.
How much do flood barriers cost for a Pass-a-Grille home?
Flood barrier systems are custom-assessed based on your opening count, dimensions, height requirements, and threshold conditions. Your free on-site assessment includes measurements and a scoped quote for your specific property. No generic estimates. Every system is fabricated to your exact openings at our St. Petersburg facility.
How bad was the flooding in Pass-a-Grille during Helene?
Hurricane Helene drove around five feet of storm surge across St. Pete Beach in September 2024, leaving sand piles and debris through the historic Eighth Avenue district and flooding ground floors across Pass-a-Grille. The Pinellas County Sheriff said the county had never seen surge like it. Weeks later, Hurricane Milton struck the same area.
Do flood barriers work for historic and Gulf-front homes?
Yes. Every system is custom-fabricated to your exact openings, so it fits older and historic homes as well as modern construction. Aerospace-grade aluminum and dual-phase EPDM compression gaskets create a watertight seal at ground-level openings, whether the water is coming from the Gulf, the bay, or stormwater backup.
How quickly can flood barriers be installed before hurricane season?
Hurricane season begins June 1. Assessment, fabrication, and installation timelines depend on opening count and current scheduling. The best window is now before storm season demand peaks. Schedule your free assessment to get a realistic installation timeline for your Pass-a-Grille property.
Do you serve the rest of St. Pete Beach and the other beaches?
Yes. Dam It Defense serves all of St. Pete Beach and the surrounding Pinellas barrier islands including Treasure Island, Tierra Verde, and the Gulf beach communities. Our in-house team handles assessment, fabrication, and installation across all of them.
