Deuel and Snyder Improvement Company Agenda Item 14a March 10, 2009 (UPDATED March 18, 2009) Page 3 of S for diversions when these rights were put in place). The Meadow Rights have two separate appropriations: Ap~ril 2, 1871 for 13 cfs and July 1, 1874 for 8 cfs. This water can only be diverted between April l Ot and July l Oth, as defined in the decree. The traditional irrigation rights (which can be used during the entire irrigation season) also have two appropriations: Apri17, 1884 for 32 cfs and November 1, 1888 for 31 cfs. The Company and its shareholders also have a recharge plan which was decreed in 2003 with the Company's plan for augnentation. The Company's average annual diversion is 4,590 AF for all water diverted into the Canal. Project Description A range of alternatives to address the rehabilitation of the sand gate structure were considered, including: 1) No action; 2) Rebuild the sand gate using a slide gate; 3) Rebuild the sand gate using a radial gate; and 4) Replace 25 feet of the river diversion structure with a new bladder gate system. Alternative 1- No Action: If the Company continues to operate with its current system, the danger to its ditch personnel remains a concern; therefore, this option was not acceptable. Alternative 2- Rebuild the sand gate using a slide gate: This alternative consists of replacing a portion of the river diversion with a five foot slide gate. This alternative would create a platform over the rollover wall. A slide gate of this size would likely require multiple personnel to operate. The cost of this alternative is approximately $80,000. Alternative 3- Rebuild the sand gate using a radial gate: This alternative consists of replacing a portion of the diversion with a five foot wide radial gate. This alternative is identical to alternative #2 except for the style of gate. The advantage of this alternative is that a radial gate can be operated by one individual. The cost of this alternative is approximately $100,000. Alternative 4- Replace 25 feet of the river diversion structure with a new bladder gate system: This alternative consists of replacing a portion of the diversion with a 25 foot wide inflatable bladder gate. This alternative will eliminate the safety concerns for personnel and increase the ability to remove sand from the Company's point of diversion. The cost of this alternative is approximately $250,000. Selected Alternative: The Company has chosen Alternative 3 and will replace a five foot section of the diversion structure with a radial gate, which will address the safety concerns and allow the Company to more easily operate the gate. The Project design is expected to be completed in March 2009. Construction is anticipated to take place in the fall of 2009.
