AI Contract Overview

Contra Costa County is seeking to repair an embankment failure and reconstruct the roadway at Pinehurst Road Milepost 1.7 in Moraga, California, to restore two-way traffic. The project, identified as Project WO4515 and CP#26-09, involves the construction of two soldier pile walls measuring approximately 40 and 80 feet long, utilizing 35-foot-deep drilled piles with root wad revetment and boulder toe armoring. Additional scope includes replacing a 24-inch corrugated metal pipe culvert with a 30-inch reinforced concrete pipe culvert and installing a new inlet, a guardrail, and thermoplastic striping. The work will require excavations up to 25 feet deep, the removal of approximately five trees, and the trimming of ten others. Potential right-of-way acquisitions and utility relocations may also be necessary. The project is anticipated to begin in summer 2027 with an estimated duration of 80 days. Construction will be managed using one-way reversing traffic control, ensuring that emergency vehicles maintain access at all times. No night or weekend work is planned, and equipment staging will likely occur within the closed lane of the roadway. The contractor must adhere to California Environmental Quality Act guidelines and implement Best Management Practices for erosion control, including the use of fiber rolls, silt fencing, and hydroseeding. All necessary regulatory permits must be secured prior to the start of construction. Primary points of contact for the project are Sandeep Kajla from the Public Works Department and Syd Sotoodeh from the Department of Conservation and Development.

Full Description

The purpose of this project is to repair an embankment failure and reconstruct the roadway to restore two-way traffic along Pinehurst Road, which was damaged during winter storm events. The road is currently limited to one travel lane. The embankment will be repaired by constructing two soldier pile walls with root wad revetment and boulder toe armoring, and by replacing a storm drain culvert that crosses underneath the roadway. The soldier pile walls will be approximately 40 and 80 feet long. The piles for the walls will be installed by drilling into 35-foot-deep holes; no pile driving will occur. Excavations up to 25 feet deep are required to install the soldier pile lagging. A guardrail will also be installed. Drainage improvements include replacing the existing 24-inch corrugated metal pipe culvert crossing Pinehurst Road with a 30-inch reinforced concrete pipe culvert to properly convey flows from the adjacent hillside. A new inlet will be installed at the culvert. The roadway thermoplastic striping will match the existing striping. Equipment staging will likely occur along the closed lane of Pinehurst Road. Appropriate Best Management Practices (BMPs), including but not limited to erosion control measures such as fiber rolls, silt fencing, and hydroseeding of temporarily disturbed areas, will be implemented during construction. Regulatory permits will be obtained before construction. Approximately five trees will be removed, and approximately ten trees will require trimming. Real property transactions, including right-of-way acquisition, may be necessary to support the project. Utility relocations may also be needed. The project is anticipated to begin in summer 2027 and take approximately 80 days to complete. During construction, one-way reversing traffic control will be in place. Emergency vehicles will always have access. Traffic control signs will be installed before and during construction. No night or weekend work is anticipated.
