Lower Latham Reservoir Company Agenda Item 26a January 19, 2010 (UPDATED February 4, 2010) Page 4 of 7 Selected Alternative No. Ib — Purchase additional LLDC Shares: This alternative was chosen because the LLDC shares have senior water rights that sustain a high yield during both average and drought years. The shares are also easily incorporated into the plan for augmentation from an operational standpoint because the location of the point of diversion and river delivery structures provide augmentation deliveries in the necessary location. Recharge Facilities Alternatives Alternative No. 2a — Underground reservoir storage constructed on property owned by the Company: This alternative was eliminated because it was cost prohibitive. Alternative No. 26 — Enlargement of the Lower Latham Reservoir: This alternative was also eliminated because it was also cost prohibitive and would require a significant increase to the existing spillway. Selected Alternative No. 2c — New recharge facilities under the Lower Latham Ditch system: This alternative included purchasing land under the Lower Latham Ditch system, constructing recharge ponds, improving laterals to the recharge sites, and modifying headgates at the laterals. This alternative was selected because it was the most economically feasible. Through this Project, the Company intends to do the following: • Purchase the Klein Farm, including: five shares of LLDC, 2-7/8 shares of the Company, two irrigation wells, and 240 acres of land with improvements; • Construct two recharge ponds at the Klein site; • Line 2,8501ineal feet of the Klein Lateral to facilitate deliveries to the site; • Purchase the Schmidt recharge site, which includes 34.9 acres of land; • Modify headgates at the north branch and south branch of the Smith Lateral; • Enlarge both north and south branches of the Smith Lateral to increase conveyance; • Construct two ponds at the Schmidt site. Schedule - The Company closed on the Klein Farm on December 15, 2009. It is currently in negotiations for the Schmidt site with final acquisition expected to occur in the next few months. Once the Company owns these properties, it is proposing the following schedule: design complete by the end of January 2010, bid in February 2010, award the bid in March 2010, construct between April and June 2010. The water rights will be added to the water court application prior to December 31, 2010. Cost - Table 2 shows the estimated Project costs. Note that the land acquisition costs are limited to the area required for the recharge ponds, sedimentation pond, and associated delivery and measurement structures.
