TCB can consider modifying this alignment to accommodate the outfall planning <br />study or land use needs. Prior to making such modifications, TCn will discuss the potential re- <br />alignment with the project sponsors. <br /> <br />TCB needs to identify what the flow path is along the south side of 96th A venue or whether the <br />flow goes under/over 96th A venue and is tributary to the proposed Arsenal North Tributary. In <br />addition, the proposed location of this tributary needs to be verified, as it appears to be located <br />north of the low point in the eontours. <br /> <br />The location of the upper part of the Elm tributary needs to be modified from what WWE shows. <br />The upper part of the Elm has been re-directed into the Arsenal North tributary. <br /> <br />ICON Engineering is evaluating the alignment of the main stem of First Creek between SH 85 <br />and Brighton Road. ICON provided TCB with a drawing showing the proposed alignment. <br /> <br />Alternative Evaluation <br /> <br />A "first cut" of the identification of flood control alternatives for the lower reach of First Creek <br />was presented by Turner Collie and Braden (TCB). Five possible detention basin locations were <br />presented that could be used to control peak flows along the main stem of First Creek. The first <br />potential detention basin presented is downstream of Peoria Street.
