<br />In order to calculale the damages from flood events. the study area was broken into
<br />reaches a~ sbown on Figure 12. Limits for the reaches were defined based upon similar
<br />land use, and the need to dt.-'1:ermine potential flood dmnage for each of the alternatives
<br />smdied. Each allernatiw protects different lengths of Pawnee Creek and the Pawnee
<br />Creek overflow, Each Reach reflects the potential flooJ damage that may occur from
<br />tlooding due to only flows in Pawnee Creek or the overflow. In the eY'Clll of a major,
<br />regional flood, extensive damage to the City of Sterling and Logan County ma)' also
<br />result from tlooding along Sand Creek, PioneCf Ditch, and tbe Soutb Platte River, in
<br />addition to Pawnee Creek. Reach I is essentially lheportion of the City of Sterling that is
<br />north of Iris Drive. Reaeb U extend, fmm his Drive '(luth to tbe northern edge of
<br />Riverside Cemetery. Reach III includes the Riverside Cemetery. and extends south to the
<br />Pawnee Creek Bridge under HWY 6. then west along Pa"'1lce Creek to CR. 33. Reaeh
<br />IV extends west along Pa"'1lee Creek fwm CR. 33 to CR. 29.

<br />Ill' Charles Leaf and Resource Consultants. The primary purpose of this report was to

<br />analysis was conducted City wide. and thl' Pawnee Creek o\'ert1ow was ju~( (,ne part of
