Following a flood event, the City of Manhattan will inspect homes and businesses in the City limits for safe and habitable conditions. If the property is located in the City’s Special Flood Hazard Area (the definition can be found in Section 10-105), a detailed inspection of the building will occur. If the damage to the building meets or exceeds the definition of being substantially damaged (also found in Section 10-105), the building must conform to the Floodplain Regulations.
Generally speaking, if a home was found to be substantially damaged (damaged 50% or more than the fair market of the home or damaged by 2 floods in a 10-year period that caused an average of 25% or more damage of its fair market value), and was built lower than today’s base flood elevation; the house would need to be elevated. This regulation is one of the City’s higher standard floodplain regulations to break the cycle of a flood, repair, and repeat and to make current properties safer from flooding.
