            Canal Lining Projects

• Components of Colorado River
  Quantification Settlement Agreement
• Settles a water rights dispute and litigation
  dating to the 1960s
• Provides 93,700 ac-ft/yr of water
• SDCWA will receive 77,700 ac-ft annually
• SLR will receive 16,000 ac-ft annually



                                                  4
History of the All American Canal Lining Project

• Congressional authorization of the Project was under PL 100-
  675, Title II signed into law by the President on November 17,
  1988
• Concrete lining was from just downstream of Pilot Knob
  (~Station 1170+27) to Drop 4, a total of about 29 miles
• During preparation of the EIS/EIR the Project was modified to
  run from Station 1250+00 to Drop 3 due to:
   – Major environmental issues between Drops 3 & 4 and costs to
     mitigate such
   – Wanted to move the starting point away from Pilot Knob, (a sacred
     area of the Quechan Indians) to eliminate any potential
     environmental/cultural conflicts
• Approved the Record of Decision (ROD) on July 29, 1994



                                                                         5
    History of the All American Canal Lining Project

•    Completed and filed EIS/EIR in July 1994
•    Reclamation undertook a Re-examination and Analysis of 1994
     FEIS/EIR and ROD which determined said documents remained
     current with the proposed action
•    California State Legislature passes SB 1765 continuously
     appropriating $200 million for the two canal projects, with $126
     million set aside for the Project. This bill was signed into law
     by the Governor on September 24, 1998
•    California voters in 2003 approve Proposition 50; includes $20
     million for the two canal projects; adds $9.65 million to Project
     for total of $135.65 million
•    Quantification Settlement Agreement (QSA) and its related
     documents signed on October 10, 2003 with the Project a key
     component to reduce California’s water use to its 4.4 million
     acre-feet apportionment



                                                                         6
 History of the Coachella Canal Lining Project

• Congressional authorization of the Project was under
  PL 100-675, Title II signed into law by the President
  on November 17, 1988
• Concrete lining from Siphon 7 to Siphon 32, a total of
  about 35 miles
• FEIS/FEIR was completed and filed on April 27, 2001
• Record of Decision (ROD) signed on March 27, 2002
• Amendment #1 to ROD signed on changing preferred
  alternative to refined parallel canal
• Key permit was the Corps of Engineers 404
  nationwide permit received in June 2004

 How does lining 78% of the canal result in recovering
               97% of seepage water?



• The seepage recovery by reach is as follows:

           Project Challenges

Project team has and is working diligently on
a fast-track basis to address a number of
design, construction, scheduling, and cost
issues to minimize costs (construction,
environmental, and operations/maintenance)
yet optimize the new canal facilities and the
required environmental mitigation.




                                                14
             Design Challenges

• New parallel alignment to minimize canal
  excavation, rights-of-way, and dewatering
• Reach 1B is most difficult—a number of
  alternatives were considered. The
  embankment in-canal alignment was selected
• Project has and will continue to be impacted
  by increases in fuel, cement, and to a smaller
  extent steel prices
• Working together to ensure that all state
  funds required based on current schedule
  are available

                                                   15
              Current Status

• Design is complete and the project is
  preparing to begin construction
• Current schedule indicates construction
  completion in Spring 2009

               SDCWA Funding

• Working together to ensure that all state
  funds required during the construction phase
  is available
  – Will ensure that all state funds are used prior to
    the need for SDCWA funds for costs over $83.65
    million for CCLP and $135.65 for AACLP
  – This will reduce financing costs to SDCWA and
    the project
