The purpose of the weirs was to slur and divert the flow to other <br />sections of tine channel, The weirs consisted of a cast -in -place reinforced concrete foundation <br />that ran up the channel slopes (Image #26, 27, 29, 30, 31), removable, sliding weir logs were <br />installed into the reinforced concrete to adjust flow rate or divert flow when needed <br />(Images # 28), Reinforced concrete modifications (Images #32 -35) were also made to the <br />existing reinforced concrete channel structure to accomodate removable aluminum weir logs <br />and divert flow. <br />This project is substantially similar to the Santa Ana Delhi Channel Diversion Project. The <br />work was in channels that are larger in size than the Santa Ana Deihl Channel and experience <br />much greater flow (Image #k 27, 31, 36). Over 1,550 CY of cast -in -place reinforced concrete <br />were required, which is more than the requiement for the Santa Ana Delhi Project. The scope <br />and type of the project was similar to what is required for the Santa Ana Delhi Channel. <br />Cast -in -Place reinforced concrete structures with metal pieces were required to modify <br />portions of the channels (similar to the Santa Ana Delhi Channel) to divert flow that was even <br />greater than what will be expected for the Santa Ana Delhi Channel (Images # 27, 29, 31, 35, <br />36), <br />For the reasons mentioned above, this project partially satisfies the minimum experience <br />requirements for the Santa Ana Delhi Diversion Project, It satisfies 7 months of the required <br />5 years experience within the last ten years In reinforced concrete flood control channels and <br />structures. It also satisfies one of the required two projects in the last 15 years in reinforced <br />concrete flood control The project satisfies the requirement of one project with a flow <br />diversion structure (in this case many). <br />Included as supplementary images are #37, 38 which show a project in Huntington Beach <br />finished in February 2007 which included a RC storm water channel for which a large RC <br />structure was constructed with tall wails like what is required in the Delhi Channel.
