Structures located in Zones A, AE, AH, AO, A99 Shaded X and X zone may be flood proofed to the Regulatory Flood Protection Elevation in lieu of elevation provided that all areas of the structure, together with attendant utility and sanitary facilities, below the Regulatory Flood Protection Elevation are watertight with walls substantially impermeable to the passage of water, using structural components having the capability of resisting hydrostatic and hydrodynamic loads and the effect of buoyancy.Īs a result of a map change, for example, a home formerly in a low-risk X zone may now be in an A zone. ![]() Out of all the policies in the state in 2012, the median premium for A zones was slightly more than $1,000, the median premium for V zones was more than $3,200, and the median premium in an X zone was $405.įlood zone(s), including any Shaded X or X zone, designation of the proposed development area as determined on the FIRM or other flood map as determined in Section 151.07 Basis for Establishing the Special Flood Hazard Areas and Section 151.08 Establishment of a Local Elevation Standard to Serve as Regulatory Flood Protection Elevation in Shaded X and X zones. ![]() According to this FIRM, the project site is located within an Unshaded X zone and is, therefore, outside of the 100-year flood zone.įor properties within an X zone, the minimum seawall elevation shall meet 3.9 feet NAVD88 and the maximum shall meet the definition of grade as determined by Section 47-2.2 (g)(1)(a).ĭue to a change in the boundaries of a SFHA, a property may be remapped into a SFHA but be allowed to retain the rates associated with the property’s former location in a B, C, or X zone.
