Document Description
Signed Notice of Determination documenting San Mateo County Board of Supervisors Approval of Final IS/MND for the Entrada Way Culvert Slip-out Bank Stabilization Project (Project or Proposed Project). The Proposed Project involves a biotechnical approach to stabilize and repair the left bank of La Honda Creek directly upstream (north) from Entrada Way in the unincorporated community of La Honda in San Mateo County, California. The bank failure threatens existing infrastructure, including stormwater infrastructure, the Entrada Way roadway, and overhead utility poles located at the top of the bank. The Proposed Project includes construction of an engineered log structure (cribwall) along the lower bank with vegetated soil lifts (VSLs) on the upper slopes above the cribwall. The existing culvert headwall parallel to the roadway would be extended approximately 22 linear feet (LF) toward the left bank. The Proposed Project also includes repositioning the creek thalweg to its original pre-erosional alignment away from the left bank and closer to the center of the channel in line with the culvert. Other Project activities include realignment of an associated storm drain pipe to discharge downstream of Entrada Way and minor roadway improvements.
