<br />) <br /> <br />1-) <br /> <br />) <br /> <br />The ALUF program requires that the existing land use information be <br /> <br /> <br />entered in a spatial data base of uniform grid sizes. The predominant <br /> <br /> <br />land use is indicated for each grid cell. We might determine from our <br /> <br /> <br />projections that residential, commercial, and industrial land use will be <br /> <br /> <br />the predominant land use in say 900, 800, and 200 grid cells, <br /> <br /> <br />respectively. <br /> <br />STEP THREE: ESTABLISH NEIl FLOODPIAIN INVENTORY <br /> <br />Analysis of future benefits is based on the projected level of <br /> <br /> <br />economic activity in the study area and its spatial distribution. The <br /> <br /> <br />analysis entails reestablishing a projected inventory for each damage <br /> <br /> <br />reach and floodzone so that depth-damage functions can be applied. <br /> <br />Once land use is established, there are three tasks in establishing <br /> <br />the future floodplain structure inventory. These are: estimating the <br /> <br /> <br />number and elevation of physical units, estimating the future value of <br /> <br /> <br />those units, and determining the susceptibility of those units to flood <br /> <br /> <br />damage. It can generally be assumed that land use patterns identified in <br /> <br /> <br />Step Two will be the same, unless there is an impending development or <br /> <br />recent change in the pattern of development that breaks with the existing <br /> <br />land use. <br /> <br />AFFLUENCE FACTOR <br /> <br />Increases in residential content-to-structure value ratios are <br /> <br />believed to increase with income over time. The affluence factor concerns <br /> <br />the extent of increase in the content-to-structure value ratio over the 50 <br /> <br />VI-9 <br />
