The City of St. Petersburg has a rule: when substantial flood damage exceeds 49% of your home's pre-damaged market value, you're required to elevate the entire house based on modern FEMA floodplain heights.
While many St. Petersburg homes sit in designated flood hazard areas, new neighborhoods like Blanc by Onyx+East are strategically built in "Zone X", the lowered flood-risk class on FEMA's National Flood Hazard Map. The substantial damage rules don’t apply in this zone.
Our builders take it a step further, incorporating materials engineered for coastal wind and humidity so new homes exceed the standards found in most of the city's housing stock.
