Unfortunately we hear these words a lot. Living in the lowcountry is geographically a location that is susceptible to flooding for a number of reasons. The number one reason that comes to mind is Hurricanes which can bring in storm surges that surpass expectations and cause much damage to your home or business. The second is new development. New development can add imperious surface area which denies saturation and natural water flow. Areas that have been uncommon flooding areas are becoming more and more susceptible to flooding.
Insurance company's use Elevation Certificates to rate your flood insurance premiums, therefore it is in your best interest to have a certificate that reflects the conditions of your home or business. The current FEMA Flood certificates contain questions on the openings around the crawlspace of the structure, how high are the openings and how many openings are around the structure.
Flood certificates can be used from prior flood policy's, but you don't know if it reflects the current characteristic's of the home or business for proper coverage ratings.
The computed elevation to which floodwater is anticipated to rise during the base flood. Base Flood Elevations (BFEs) are shown on Flood Insurance Rate Maps (FIRMs) and on the flood profiles.
The BFE is the regulatory requirement for the elevation or floodproofing of structures. The relationship between the BFE and a structure's elevation determines the flood insurance premium.
Zone C, Zone X - Areas determined to be outside 500-year floodplain determined to be outside the
1% and 0.2% annual chance floodplains.
Zone B, Zone X500 - Areas of 500-year flood; areas of 100-year flood with average depths of less than 1
foot or with drainage areas less than 1 square mile; and areas protected by levees
from 100-year flood. An area inundated by 0.2% annual chance flooding.
Zone A - An area inundated by 1% annual chance flooding, for which no BFEs have been
Zone AE - An area inundated by 1% annual chance flooding, for which BFEs have been
Zone VE - An area inundated by 1% annual chance flooding with velocity hazard
(wave action); BFEs have been determined.
