Elevating buildings above the <br />base flood level is a common technique for reducing <br />flood damage. Flood insurance requirements mandate <br />that residential buildings in flood-prone areas be elevated <br />and that other types of buildings be elevated and/or <br />floodproofed It is a particularly useful technique where <br />site elevations are consistently below the base flood eleva- <br />tion, and offers the greatest assurance of keeping a build- <br />ing dry during flooding <br />One method of raising buildings is to use fill mate- <br />rial to achieve the desired elevations. This technique in- <br />teracts with the various site design issues, and requires <br />consideration of the type of filL compaction and settle- <br />ment of filL protection against erosion, and the effect of <br /> <br />Buildings can be raised <br />above tbe BFE by the use of <br />fill material. <br /> <br /> <br />\ <br />h.
