<br /> <br />, <br /> <br />EuildinqCodes <br />A ~ell~written and properly enforced building code Can <br />effecti"..ly reduce damages to buildings in the flood plain during <br />flood periods. A few of the requirements which should be specified <br />in a building code to reduce flood da~ges are, prevent flotation <br />of buildings from their fo~dations by re~iring proper anchorage 1 <br />establi~h basement elevations and minimum first floor elevations <br /> <br />" - <br />. . <br />~ ~ " <br />.., <br />" . <br />. . . <br />. . 0 <br />o <br />"., <br />~ 4 ::: <br />. <br />. <br />. - . <br />~ " '" <br />--- <br />::'~~~ <br />o ~ ~ " <br />" - ~ ~ <br /> <br />consistent with potential floods; require structural strength to <br />withstand water pressure or high velocity of flowing water; restrict <br />the uSe of materials whiCh deteriorate rapidly when exposed to water~ <br />prohibit equipment that might be hazardous to life when submerged, <br />such as a chemical storage, boilers or electrical equipment. <br /> <br />Development policies <br />While all regulatory controls are valuable tools in <br />comprehensive flood damage prevention planning, probably the most <br />effective tool is in the area of developro.",nt policies, "Flood <br />conscious"governm",ntalpoliciesthatliIllittheextensionofpubliC <br />roads, utilities and other services into flood prone areas can play <br />an important indirect role in Shaping overall development.
