<br />, <br />,I <br /> <br />Damage estimates for the Midwest flood show marked <br />inconsistencies. No federal agency is responsible for <br />developing accurate assessments of flood damages. nor <br />is funded to do so. The affected states and the Federal <br />Emergency Management Agem::y (FEMA) conduct <br />preliminary damage assessments to t!c:tenllinc if a <br />Presidential disaster declaration is warrameu and (() <br />estimate the resources necessary for response and <br />recovery. Once sufficient damage has been identitied <br />that justities a declaralion and once FEMA has a <br />general idea of how resources should he allocated, <br />federal agencies have liule il1l.:entive (() expend <br />resources updating preliminary asst:sSIHl::llts. Resourct:s <br />afe instead focused un tracking and projecting <br />expenditures. The NWS is not funded (() eslimate ((Hal <br />damages hut does so (0 suppon other missions. The <br />USACE. which in Ihe past eSlimated tlood damages, is <br />no longer funded to do so. The Revit:w Committee is <br />com;erned lhat decisions involving hundreds of millions <br />of dollars onen are being madt: withoul syslematic <br />assessments of flood damages and without a t.:h:ar <br />underslanding of the nalUrt: allll t:xteIH of lhose <br />damages. <br /> <br />Agriculture <br /> <br />Agricullural d:unages from Ihe Flood of 1993 had two <br />primary t.:aust:s: excessive moisture thaI prevt:llted <br />planting and reduced yields ill upland and floodplain <br />areas ami at.:lUal tlooding (hat destroyed t.:rops and <br />severely d:unaged many acres of lertile floodplain <br />c.:ropland. "is diftkult to separate the fac.:wrs that <br />intluent.:ed crop production during Ihe 1993 growing <br />season in the 9-slate region. They included rain, low <br />temperatures. early frost. and tloods. More than 70 <br />percent of the crop disaster assistant.:e payments, <br />however. were made to coumies in upland areas d 1l0{-~~ <br />ill main stem river floodplains. n <br /> <br />Agril:ultural damages direc[ly allrihuted (0 actual <br />flooding lOtaled more thall $2.5 hill ion, with an <br />estimated $1.4 hillioll in lost corn and soybean sales. <br />Most of these losses wen: reslricted to 1993 as (he <br />productive capacity of [h~ land was unc.:hanged. There <br />wt:re, however. damages 10 field fertility and fann <br />infrastructurt: of at least $100 million. <br /> <br />Each state suffered difkrelH types of losses. For <br /> <br />16 <br /> <br />, <br /> <br />THE FLOOD OF 1993 <br /> <br /> <br />example, Missouri with 34 percent of its cropland (5.1 <br />million acres) in the floodplain, had crop damages from <br />flooding on 3.1 million acres causing $247 million in <br />lost sales.'4 In lIIinois, only 3 percem of the state's <br />corn and soybean acreage (312.000 and 276.000 acres <br />respectively) were lost to nooding with a loss in sales <br />of$153A million." Minnesota fanners losl $500 <br />million in crop sales. but most of the damage was <br />caused by wet conditions rather than riverine flooding. 16 <br /> <br />D:unage from scour and deposition affected 455.000 <br />acres on the Missouri River floodplain representing 20 <br />percent of Ihe flooded cropland along Ihe Miss~ri and <br />Mississippi rivers. I? . Drainage ditches were filled with <br />sediments, and other agric.:ultural infrastructure was <br />deslroyed. Almosl 60,000 acres have sand deposition <br />more than 24 inches thick and reclamation costs to <br />restore fertility to damaged cropland are approximately <br />$190/acre. I~ I f cropland restoration requires removal of <br />sand. il will COSI approximately $3,200 to remove each <br />acre-foolofsand.'9 It will cost-$10.8 million to remove <br />sediment and dehris from ditches.20 <br /> <br />St:c.:ondary impac.:ls of agricultural losses to a local <br />economy vary substantially with the dependeIlce of that <br />ec.:onomy on the agricultural sector. Immediate losses <br />are due 10 lost sales and unemployment. In the long <br />run. the assessed value of land that sustained long-lenn <br />damage may he reduced which will affecI Ihe property <br />tax base of affet.:ted conununilies. <br /> <br />Another secondary effec.:[ was a reduction in c.:rop- <br />support payments aher prices adjusted to the reduced <br />
