Community plans often <br />involve mixing and combining solutions to <br />address unique flooding situations. You can <br />also use the following solutions to address <br />other goals such as economic development, <br />preserving historic areas, and rehabilitating <br />housing. <br /> <br />Acqu isitionj relocation <br /> <br />The preferred method of flood hazard mitiga- <br />tion; acquiring and relocating structures outside <br />of the floodplain benefits the community in <br />many ways: <br /> <br />,f Removing the structures from the flood- <br />plain ensures they will not be damaged <br />during the regional flood and eliminates <br />the perils or risk of flooding to life and <br />property. <br /> <br />,f Provides open space for the community, <br />such as park land. <br /> <br />./ Removing these structures also reduces the <br />chance of water pollution by removing <br />potentially hazardous material from the <br />floodplain. <br /> <br />Most acquisition/relocation projects are <br />voluntary agreements with the property owners. <br /> <br /> <br />\\t\.\)~_\~~ <br /> <br />-~-....... <br /> <br />~. <br />~.. ,. <br />- - 'k.
