Mills Canyon Sewer Access Road Repair Project
This project addressed the maintenance access road that had eroded. The erosion on the maintenance road had compromised the integrity of the existing sewer line and access to maintain the existing sewer line.
Scope: The City of Burlingame repaired three areas of the Mills Canyon Sewer Access Road where soil movement had resulted in damage to the road. Project work included construction of three new soldier piles and lagging retaining walls consisting of steel beams embedded in cast-in-drilled-hole (CIDH) caisson foundations with treated wood lagging, installation of wall back-drains, removal of soil and replacement with new engineered fill or controlled-low-strength-material, installation of surface drainage improvements, and installation of new asphaltic concrete road and dikes.
