Entrada Way Culvert Slip-out Bank Stabilization Project

The Entrada Way Culvert Slip-out Bank Stabilization Project is a locally administered infrastructure initiative by the San Mateo County Department of Public Works to address critical bank erosion along the left bank of La Honda Creek upstream of Entrada Way in the unincorporated community of La Honda, California. The project employs a biotechnical approach combining engineered log structures (cribwalls) along the lower bank with vegetated soil lifts on the upper slopes to stabilize the failing bank, which threatens the Entrada Way roadway, stormwater infrastructure, and overhead utility poles. To further mitigate erosion and restore natural channel dynamics, the creek’s thalweg will be repositioned to its pre-erosion alignment near the center of the channel, aligned with the culvert, while the existing culvert headwall will be extended approximately 22 linear feet toward the left bank. Additional work includes realigning an associated storm drain pipe to discharge downstream of Entrada Way and undertaking minor roadway improvements. The project was approved through a Final Initial Study/Mitigated Negative Declaration under CEQA, with environmental mitigation measures tied to specific identifiers such as P-43-000562 and CA-SCL-000567, though no formal federal contract clauses, acquisition regulations, or pricing details are included in the documentation. Construction is scheduled to begin on June 1, 2026, with all work performed on-site at the specified location near Highway 84 and APN 083-051-110. No formal contract value, solicitation number, or procurement structure has been established, as the documentation reflects an environmental compliance and project approval record rather than a federally governed acquisition. There is no specified contract type, payment office details, or invoicing methodology, and financial transactions tied to the project are limited to environmental review fees totaling $3,093.75 processed via county check. The County of San Mateo retains oversight through its Natural Resource Manager, Julie Casagrande, with public comments and submittals directed to the Department of Public Works in Redwood City. While site-specific mitigation and cultural resource assessments are referenced, no federal procurement requirements such as FAR clauses, COR/COTR assignments, offeror certifications, or evaluation factors for award are applicable or present. Inspection and acceptance protocols are governed by CEQA guidelines and National Historic Preservation Act standards, with compliance monitored at the project site and formally reviewed through the County’s administrative offices. The project relies on local
