The Advisory Base Flood Elevations are higher than the elevations depicted on the effective FIRMs because they are based 35 additional years of flood data, including the effects of Hurricanes Katrina and Rita, in addition to accounting for the impacts of subsidence and the degradation of the coastal barriers.
