The SCADA system will incorporate several remote <br />sensors throughout the Dry Creek basin at an estimated cost of $150,000. The total estimated <br />cost for the East Vine Diversion with the SCADA system was $1.15 million. <br /> <br />5.3.3 Boxelder Creek Diversion <br /> <br />The Boxelder Creek Diversion is similar to the East Vine Diversion. The flood flows would be <br />released at Boxelder Creek rather than back to the existing Dry Creek. The introduction of flood <br />flows from the Dry Creek Basin to Boxelder Creek requires that the discharges be contained <br />within the existing banks or a flood easement may need to be purchased from the adjacent <br />landowners. The diversion of flood flows to Boxelder Creek reintroduces the water rights issues <br />that were considered with the Willox Lane Diversion. <br /> <br />A labyrinth spillway was designed to pass 3,000 cfs, without overtopping the Larimer and Weld <br />Canal. The preliminary layout of the labyrinth spillway is shown in the Technical Appendix. <br />The gate structure, SCADA system and labyrinth weir were estimated to cost approximately <br />$500,000. The cost does not include any land or flood easement costs. <br /> <br />T:lProjecls\6824660Dry CrkDiversionLarimerCounty\Sub_OO\12.0 Word Proc\Flood Control P1an-Rpldoc 04124100(11:14 AM) 5-5 <br />
