<br />This technique is particularly applicable for mobile homes, which are <br />not conducive to floodproofing. <br /> <br />If elevated high enough, you could give yourself a new carport. <br /> <br />Problems of Elevation and Evacuation <br /> <br />Unless the house is evacuated, there will be water under it making <br />access difficult during a flood. <br /> <br />Additional expenditures may be needed to improve the appearance. <br /> <br />Your basement will probably be unprotected. <br /> <br />Costs: Consult your local contractors. You can expect at least $5,000 <br />to elevate a building. Evacuation would cost at least $10,000 more, <br />with most of the cost going to preparation of the new site. These costs <br />would be much less for a mobile home. <br /> <br />D. Dry Floodproofing <br /> <br />Dry floodproofing is a series of adjustments made to your house to keep <br />water from entering during a flood. The ideas presented in this section <br />are not to be confused with floodproofing measures to be taken when <br />building a new house. Normally, building code requirements are much <br />more restrictive on what is permitted when building a new floodproofed <br />structure. <br /> <br />To dry floodproof an existing building, four factors need to be taken <br />into account: <br /> <br />1. Static lateral pressure: the walls must be able to resist <br />the pressures of standing water pushing sideways. <br /> <br />2. Uplift: the floor must be able to resist the pressures of <br />water pushing upwards when the ground is saturated. <br /> <br />3. Waterproofing: the walls and floor must be watertight and <br />all openings must be closed and made watertight. <br /> <br />4. Dynamic loads: the building must be able to withstand the <br />shocks and pressures that may accompany a flood. <br /> <br />Dry floodproofing is a very difficult business. If done wrong, the <br />walls may collapse causing more damage than if the building were per- <br />mitted to flood. Dry floodproofing measures should be designed by a <br />structural engineer who can prepare the best design that takes into <br />account the peculiarities of your house, soils, and expected flooding. <br />The following ideas are offered with this recommendation for consulting <br />an engineer. These ideas should help you decide if dry floodproofing <br />is feasible for your situation. <br /> <br />10 <br />
