<br />ESTIMATED ANNUAL DAlfAGES (!AD)
<br />Land use information, the topography of the atudy area, and the
<br />stage-frequency data were correlated with stage-damage relationships to
<br />estimate flood damages at Malta. The existing right-bank foresight levee
<br />is not recognized as adequately providing flood protection and is not
<br />credited with preventing any flood damages. This is because of the lack
<br />of structural integrity.
<br />
<br />The flood damage potential for Malta includes damage to buildings and
<br />their contents as well as damage to public facilities within the 500-year
<br />flood plain. Damage to public facilities includes utilities, roads,
<br />parks, and bridges. Also included in the damage estimates are flood
<br />cleanup costs. These costs were included in the damage analysis as a
<br />percentage of the total damage to structure and contents. The percentage
<br />is based on previous Omaha District studies. It was detemined to be
<br />approximately 11 percent of the damage developed for structures and their
<br />contents. This percentage was used for all flood events examined.
<br />
<br />The total EAD for the Milk River study area 18 $116,200. The !AD for
<br />subareas I, 2, and 3 are $73,500, $27,100, and $15,600, respectively.
<br />Table 5 presents the estimated !AD and the damage-frequency relationship
<br />for each subarea.
