<br /> <br />Figure 4.59 Connected Utility Service Tank <br />Foundation <br /> <br />damaged. Where external components, such as <br />an outdoor compressor/evaporator unit are <br />installed, they must also be elevated above an- <br />ticipated flooding. As with utility service tanks, <br />these components are best located adjacent to the <br />manufactured home on a separate platform sup- <br />ported by the elevated structure. <br /> <br />Access and Egress <br />A clear access and egress path to the manufac- <br />tured home must be provided to allow evacuation <br />and rescue efforts necessitated by a flood. Access <br />and egress should be addressed during the <br />evaluation of a potential site to ensure feasible <br />alternates exist. Necessary considerations may <br />also include bridges, walkways, and areas of safe <br />refuge which allow safe evacuation during <br />flooding. <br /> <br />Having considered Chapters I-IV of the manual <br />a determination on the usability of a particular <br />flood-prone site for manufactured housing should <br />be possible. Where use of the land is feasible, at <br />least one candidate design may be available for <br />consideration. Such a site design could include <br />site modifications, elevation of the manufactured <br />home, anchoring or evacuation based upon an <br />assessment of the flood forces and capacity of any <br />candidate designs. <br />The design work sheet provided in Appendix F <br />should be used in developing candidate designs <br />in conformance with the manual. <br />Having developed a candidate design(s), the <br />ability of the design(s) to survive anticipated flood <br />occurrences should be assessed. At a minimum, <br />the design would have to comply with the provi- <br />sions of the National Flood Insurance Program <br />(NFIP) which include certain tie-down and eleva- <br />tion requirements as previously discussed. <br /> <br />Based on an evaluation of the site, other <br />measures may !;Ie warranted whic~ will further <br />reduce the potential for damage. These measures <br />may, however, require additional costs over'and <br />above those necessary to comply with the <br />minimum NFIP requirements. However, they will <br />afford a greater probability of flood damage loss <br />reduction which may offset or exceed the <br />necessary costs to attain the additional protection. <br />Chapter V discusses the costs associated with <br />improving the flood loss reduction potential for a <br />manufactured home siting technique(s), <br /> <br />70 <br />
