As part of the effort to remove, relocate and replace approximately 2.5 miles of the Escondido Canal that crosses through the San Pasqual Indian Reservation, the project team had to accomplish three major tasks. First was constructing a desilting basin, followed by demolishing and replacing the existing canal, then installing a 60-in. pipeline, all of which was completed in May 2023.

The 110-ft-long by 32-ft-wide desilting basin is a hydraulic structure within the 100-ft city right-of-way that required large retaining walls and an all-weather access road. The first half-mile of the open canal was replaced with 60-in.-wide by 48-in.-high precast concrete box culvert.
