California Aqueduct Reach 4 Verizon Fiber Optic Lines Repair
Document Type
NOE - Notice of Exemption
Document Description
Existing Verizon fiber optic communication lines are used to remotely operate existing California State Water Project (SWP) infrastructure. A portion of this line in California Aqueduct (Aqueduct) Reach 4 (between Check 14 and Check 15) is damaged. Failure to immediately repair the existing line could cause loss of the ability to remotely monitor and control SWP infrastructure. Currently scheduled repairs will occur on the right side (R) of the Aqueduct at milepost (MP) 98.48R, MP 99.81R, and MP 100.23R, but repairs may be made anywhere between Aqueduct Checks 14 and 15. At each repair site, an approximately 8-foot-long, by 6-foot-wide, by 6-foot-deep excavation will be made. Once the excavation is made, the line will be located and assessed for damage. The damaged lines will be repaired by splicing new fiber optic material into them in an on-site Verizon splice-lab trailer. The repaired lines will be reinstalled in the excavation, and each excavation will be backfilled and compacted to original contours.
