How New Flood Hazard Maps Affect Construction (Engineers, Surveyors, Developers)
Osceola County uses the results of the most current set of Flood Insurance Rate Maps and its accompanying Flood Insurance Study to guide compliance and site planning. The new, revised Flood Maps will be considered the "best available data" and used for new construction when they illustrate more restrictive (higher base flood elevations) than the current effective flood maps.
Base Flood Elevations on the new maps are related to the North American Vertical Datum, 1988 (NAVD 88).
