Check whether a specific Houston-area address took on water during Hurricane Harvey in August 2017, based on modeled high-water-mark data.
Free lookup. No account required. Greater Houston coverage.
Hurricane Harvey dropped more than 50 inches of rain on parts of Houston and flooded well over 150,000 structures, many of them outside the mapped flood zone. Whether a home flooded in Harvey is one of the most useful facts a buyer can have, and it rarely appears on a listing. This free tool estimates the Harvey flood depth at a specific address.
Floodfolio compares the location to Hurricane Harvey high-water data and reports the estimated flood depth at that point. A result above zero means floodwater is modeled to have reached the location. A dry result means the location does not show up in the Harvey high-water data.
Harvey was the clearest stress test Houston has had in a generation. A home that stayed dry through Harvey has a meaningful track record. A home that flooded, even if it is now repaired and outside the flood zone, carries information a buyer deserves before making an offer.
Enter the address above. Floodfolio estimates the Hurricane Harvey flood depth at that location from modeled high-water data and shows whether the spot took on water in August 2017.
No. The result is based on modeled high-water data, not a property inspection. It is a strong signal, but localized drainage, the exact structure footprint, and repairs since 2017 are not captured. Treat it as research, not a guarantee.
Because the flood zone is a prediction and Harvey is what actually happened. Many homes that flooded in Harvey were outside the mapped high-risk zone. Past flooding is one of the strongest indicators of future risk.
Disclosure rules vary and depend on what the seller reports. This tool gives you an independent read from federal storm data so you are not relying only on a disclosure form.
