Document Description
This is a modification to approximately 134-feet of the south bank of San Mateo Creek in San Mateo County, CA where a sackrete revetement was previously installed. The proposed Project will stabilize the south bank of San Mateo Creek in the Study Area resulting from severe erosion during winter flows of December 2022 and January 2023. Specifically, the remediation will replace unpermitted sackrete revetment with a restored natural bank of boulder revetment, anchored large wood structures, and willow/dogwood/bay laurel inter-plantings. Post construction monitoring and maintenance will be provided for a minimum of five years to ensure the bank performs as designed and the enhanced plantings become established. The Avoidance and Minimization Measures incorporated into the Biological Assessment, together with conditions imposed as part of the authorizations from the regulatory agencies will ensure that there would be no significant adverse impacts on any special-status species or their habitat.
