<br /> <br />Chapter VI: General Design Practices <br />Elevation <br /> <br />entitled Flood Resistant Materials Requirements for Build- <br />ings Located in Special Flood Hazard Areas in Accordance <br />with the National Flood Insurance Program, <br /> <br />Step 9: Design utilities extensions. <br /> <br />The field investigation will reveal the specific utility systems <br />that will require relocation, extension, or modification, <br />Where possible, utility systems should be relocated above <br />the flood protection level. Local utility companies should <br />be contacted about their specific requirements governing the <br />extension of their utility service. In many instances, the <br />local utility company will construct the extension for the <br />homeowner. Critical issues in this extension process in- <br />clude: <br /> <br />. handling of utilities encased in the existing slab or walls; <br /> <br />. coordination of disconnection and reconnection; <br /> <br />. any local codes that require upgrades to the utility <br />systems as part of new construction or substantial repair <br />or improvement; <br /> <br />. introduction of flexible connections on gas, water, <br />sewer, and oHlines to minimize potential for seismic <br />damage; <br /> <br />. potential for relocation or elevation of electrical system <br />components from existing crawl space and/or basement <br />areas; and <br /> <br />. design of separate GFI-type electrical circuits and use of <br />flood-resistant materials in areas below the BFE, <br /> <br />VI .
