<br />formulation purposes, the study area was divided inlOthrCc reaches as in the Gingery
<br />study. Reach A consist~ of subarea~ 14 through 17, reach B consist~ of subareas 6
<br />through 13, ami reach C consists of subareas I through 5.

<br />Land use data were colle<:tcd in the 500-year flood plain of Dry Creek for each of
<br />the 17 subareas. There are 675 residential and 254 nonresidential structures in the
<br />500-year flood plain. The number of buildinp identified during the land u<;e survey alld
<br />their values, including contents, are shllwn in tallle 4-2, Subarcas 4 and 5 were found
