canal lining projects
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
history of the all american canal lining project
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

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
history of the coachella canal lining project
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

  • Construct approximately 23 miles of lined canal adjacent to existing canal
  • DWR funding up to $135.65 Million
  • Current estimates indicate significant overrun of available funds
  • Design is complete.
  • Construction is expected to be completed in Spring 2009

how does lining 78 of the canal result in recovering 97 of seepage water
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 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.

design challenges
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
current status
Current Status
  • Design is complete and the project is preparing to begin construction
  • Current schedule indicates construction completion in Spring 2009

  • DWR funding up to $83.65 Million
  • Construction awarded for $71,198,900
  • Current estimates for environmental and other areas indicate available funds will be exceeded

design construction challenges
Design/Construction Challenges
  • With parallel canal, raised the invert of the canal 4 feet (from 2 feet below existing canal invert to 2 feet above existing canal invert)
  • Developed a large mammal safety and water source strategy
  • Performed ecological value assessment to meet environmental commitments in an economically sound manner
current status1
Current Status
  • Construction is slightly ahead of schedule
  • Construction is approximately 97% complete
  • Lining of the canal was completed in August 2006
  • Tie-ins to existing canal completed in November 2006
  • Water cutover occurred on December 4, 2006
  • Total excavation – 5.6 million cubic yards (approx.)
  • Structural concrete – 37,000 cubic yards (approx.)
  • Concrete lining – 1.3 million square yards (approx.)
  • Fencing and electrical work is in progress
sdcwa funding
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
