KOA provided construction management and inspection services for the replacement and realignment of a portion of existing sewer beginning at the intersection of Lambert and Tamarack Avenue, traveling north in Tamarack Avenue, east through the Tamarack Park parking lot, then along the westerly side of the Brea Canyon Channel right-of-way, east underneath the channel and through an easement before connecting to the existing sewer in Pepper Tree Road. Approximately 1,600 linear feet of 10-inch to 18-inch diameter sewer was proposed for this project which included the removal and replacement of 30 linear feet of 10’Wx8’H reinforced concrete box and 25 linear feet of 48’Wx11’H reinforced concrete rectangular channel. The project utilized pipe bursting operation to install the new sewer line between residential properties and cut-outs in the flood control channel to install the new sewer line under the flood control channel.
