Add Additional Elevation (Freeboard) above the minimum BFE + 1 foot required by the 6th. Ed. FBC FPM ordinance text changes and – local technical code amendments (FBC, R and FBC, B) NEW REQUIREMENTS IN 6th Ed. FBC! The 6th Edition FBC requires all buildings to be elevated to or above the Base Flood Elevation (BFE) plus 1 foot. The requirement is new to the FBC, Residential. The FBC, Building has required a minimum of BFE + 1 ft since 2010. CRS Note. With all communities now required to enforce the FBC with BFE + 1 ft, CRS credit should be available to those communities that did not previously adopt at least BFE + 1 ft. See guidance prepared by DEM to help CRS communities satisfy the CRS/ISO documentation related to the FBC and freeboard requirements (link below). Description: Elevating buildings higher than the minimum base flood elevation required by the NFIP reduces the frequency and severity of flood damage. Reflecting that reduction, NFIP flood insurance premiums are lower for individual buildings that are elevated above the minimum BFE (see graphic). An independent study conducted for FEMA determined that the incremental cost of additional elevation can be offset within a few years (depending, of course, on a number of factors such as foundation type; elevation on fill tends to be the most expensive method of elevation). See the last page for additional reasons to consider elevating buildings higher than the minimum requirement. How the 6th Ed. FBC, Building specifies BUILDING elevations: The FBC, B does not specify building elevations in the body of the code. Rather, it is done by reference to ASCE 24 which requires buildings within the scope of the FBC, B to be above the BFE as a function of flood zone and risk category. To see the existing
