ARE THERE ADDITIONAL REQUIREMENTS THAT COMMUNITIES SHOULD CONSIDER ADOPTING BESIDES THE ADVISORY BASE FLOOD ELEVATIONS?
Yes. NFIP floodplain management requirements have special provisions that apply in coastal high hazard areas or V zones. Because these areas are subject to wave impacts and high velocity floodwaters, buildings must be elevated on piles or columns so the bottom of the lowest horizontal structural member (usually a floor beam) is above the BFE. This allows waves to pass under the building. Recent experience has shown that wave impacts and debris are a problem in many coastal areas which are currently designated as A zones or even as B, C, and X zones. To adequately protect buildings from wave impacts, communities should consider requiring V-zone construction methods in any zones where waves were experienced during Hurricanes Katrina and Rita. These areas can be determined using the same calculation used to calculate the wave height. Communities should consider requiring V zone type construction in any area where the wave height is greater than one foot. This could include areas designate
