Slide 4

Canal Lining Projects Components of Colorado River Quantification Settlement Agreement Settles a water rights question and case dating to the 1960s Provides 93,700 air conditioning ft/yr of water SDCWA will get 77,700 air conditioning ft every year SLR will get 16,000 air conditioning ft yearly

Slide 5

History of the All American Canal Lining Project Congressional approval of the Project was under PL 100-675, Title II marked into law by the President on November 17, 1988 Concrete coating was from recently downstream of Pilot Knob (~Station 1170+27) to Drop 4, a sum of around 29 miles During arrangement of the EIS/EIR the Project was adjusted to keep running from Station 1250+00 to Drop 3 because of: Major ecological issues between Drops 3 & 4 and expenses to moderate such Wanted to move the beginning stage far from Pilot Knob, (a sacrosanct region of the Quechan Indians) to wipe out any potential natural/social clashes Approved the Record of Decision (ROD) on July 29, 1994

Slide 6

History of the All American Canal Lining Project Completed and recorded EIS/EIR in July 1994 Reclamation embraced a Re-examination and Analysis of 1994 FEIS/EIR and ROD which decided said archives stayed ebb and flow with the proposed activity California State Legislature passes SB 1765 consistently appropriating $200 million for the two trench ventures, with $126 million put aside for the Project. This bill was marked into law by the Governor on September 24, 1998 California voters in 2003 affirm Proposition 50; incorporates $20 million for the two trench ventures; adds $9.65 million to Project for aggregate of $135.65 million Quantification Settlement Agreement (QSA) and its related archives marked on October 10, 2003 with the Project a key part to lessen California\'s water use to its 4.4 million section of land feet distribution

History of the Coachella Canal Lining Project Congressional approval of the Project was under PL 100-675, Title II marked into law by the President on November 17, 1988 Concrete coating from Siphon 7 to Siphon 32, a sum of around 35 miles FEIS/FEIR was finished and documented on April 27, 2001 Record of Decision (ROD) marked on March 27, 2002 Amendment #1 to ROD marked on changing favored other option to refined parallel channel Key allow was the Corps of Engineers 404 across the country allow got in June 2004

AACLP Project Elements Construct roughly 23 miles of lined waterway contiguous existing trench DWR subsidizing up to $135.65 Million Current assessments demonstrate critical invade of accessible assets Design is finished. Development is relied upon to be finished in Spring 2009

67,700 Acre-Feet every Year of Water Conserved from Lining the All-American Canal SLR 11,500 air conditioning ft SDCWA 56,200 air conditioning ft

Slide 13

How does lining 78% of the waterway bring about recouping 97% of drainage water? The leakage recuperation by reach is as per the following:

Slide 14

Project Challenges Project group has and is working perseveringly on a most optimized plan of attack premise to address various outline, development, planning, and cost issues to minimize costs (development, ecological, and operations/support) yet upgrade the new trench offices and the required natural moderation.

Slide 15

Design Challenges New parallel arrangement to minimize trench exhuming, privileges of-way, and dewatering Reach 1B is most troublesome—various options were considered. The dike in-trench arrangement was chosen Project has and will keep on being affected by increments in fuel, bond, and to a littler degree steel costs Working together to guarantee that all state stores required in light of momentum calendar are accessible

Slide 16

Current Status Design is finished and the venture is planning to start development Current timetable shows development fulfillment in Spring 2009

CCLP Project Elements Construct around 35 miles of lined channel nearby existing waterway Construction started October 2004 Project anticipated that would be finished April 2007 DWR subsidizing up to $83.65 Million Construction granted for $71,198,900 Current appraisals for natural and different territories demonstrate accessible assets will be surpassed

Slide 25

Design/Construction Challenges With parallel channel, raised the transform of the trench 4 feet (from 2 feet beneath existing waterway modify to 2 feet above existing channel upset) Developed a huge warm blooded animal security and water source system Performed biological esteem evaluation to meet ecological responsibilities in a monetarily solid way

Slide 26

Current Status Construction is somewhat in front of calendar Construction is roughly 97% finish Lining of the trench was finished in August 2006 Tie-ins to existing waterway finished in November 2006 Water cutover happened on December 4, 2006 Total removal – 5.6 million cubic yards (approx.) Structural cement – 37,000 cubic yards (approx.) Concrete covering – 1.3 million square yards (approx.) Fencing and electrical work is in advance

SDCWA Funding Working together to guarantee that all state reserves required amid the development stage is accessible Will guarantee that all state assets are utilized preceding the requirement for SDCWA reserves for expenses over $83.65 million for CCLP and $135.65 for AACLP This will lessen financing expenses to SDCWA and the venture
