City of Redondo Beach Legado Development Sewer Upgrades

Redondo Beach, CA


PACE designed approximately 550 feet of new 12-inch sewer pipe and multiple manholes through various major intersections and along Pacific Coast Highway to provide additional conveyance capacity for the City of Redondo Beach. The pipeline traverses a Caltrans highway and the City of Torrance right-of-way, so multiple encroachments were required for the project. PACE evaluated numerous alignment alternatives and trenchless construction technology through pipe bursting. PACE concluded that the existing pipe was too shallow for pipe bursting and was able to identify an alignment to cross both over and under existing underground utilities. During construction, the contractor submitted an alternate construction approach called “Pilot-Tubing,” a trenchless technology. PACE evaluated the new construction method and agreed it was beneficial for the City to proceed. This trenchless method significantly reduced construction traffic impact with some cost savings to the City.


Key Features:

  • Trenchless pipeline installation
  • 12-inch vitrified clay pipe (VCP) sewer requiring permits from multiple public entities
  • Existing sewer pipe retained in operation for added redundancy
  • Multiple pipeline alignments evaluated to avoid existing underground utilities
