Slip-out Repair and Bank Stabilization Near 1780 Higgins Canyon Road Project

The Slip-out Repair and Bank Stabilization Near 1780 Higgins Canyon Road Project is an initiative by the California San Mateo County Department of Public Works to perform critical road repairs, bank stabilization, and habitat enhancement along the southwestern bank of Mills Creek in Half Moon Bay. Approved on November 12, 2025, and certified under CEQA guidelines via a Negative Declaration, the project aims to restore the failed bank and bed of Mills Creek and repair the damaged roadway. The primary point of contact for the project is Natural Resource Manager Julie Casagrande. Technical specifications for the project include the installation of a 192-linear-foot soldier pile retaining wall and 185 feet of biostabilization-based bank repair using soil lifts and vegetated boulder revetments. Additionally, the scope involves restoring 110 linear feet of engineered creek bed to its original flowpath and reconstructing 180 linear feet of failed roadway. This roadway work requires the removal of 2,116 square feet of existing asphalt and the installation of 4,556 square feet of new asphalt to restore the travel lane and shoulder to a width of approximately 20 feet.
