<br />Types of Residential Structures That Can Be Elevated <br /> <br />~ <br /> <br />FEMA's post- and pre-FIRM <br />requirements do not allow <br />basements below the Base Flood <br />Elevation (BFE) for substantially <br />damaged/improved and post- <br />FIRM applications, For more <br />information on what retrofitting <br />measures are allowable under <br />FEMA guidelines, refer to <br />Chapter II, Regulatory Frame- <br />work, <br /> <br />HOUSES OVER BASEMENTS <br /> <br />These houses are slightly more difficult to elevate because <br />their utilities are usually in the basement. In addition, <br />basement walls may have been extended to the point where <br />they cannot structurally withstand flood forces. Houses <br />over basements can be: <br /> <br />. elevated on solid fOWldation walls by creating a new <br />masonry-enclosed area on top of an abandoned and <br />filled-in basement (see Figures VI-E9 through VI-ElO); <br />or <br /> <br />. elevated on an open foundation, such as masonry piers, <br />by filling in the old basement (see Figures VI-Ell and <br />VI-E12). <br /> <br />Engineering Principles and Practices of Retrofitting Flood-Prone Residential Structures <br />January 1995 <br /> <br />VI- E,11 <br />
