Surfers' Beach


Surfers' Beach Pilot Restoration Project (Harbor District)

Surfers’ Beach July 2016

In 2015 the Harbor District initiated a Pilot Surfers’ Beach Sand Replenishment Project as a reduced scale of the Army Corps preferred alternative, and began seeking grant funding and stakeholder partners.  The pilot project involves a one-time placement of up to 100,000 cubic yards of east basin dredge material onto Surfers’ Beach between the jetty and Coronado St, using a suction dredge and pumping system to transport a sand slurry via pipeline.

Construction is anticipated in spring/summer 2024, beginning with an eelgrass mitigation project in the west basin required by permitting agencies. If the follow-up 2-year monitoring program finds that the project is effective and does not cause unacceptable environmental impacts, then a larger beach nourishment project would be pursued in the future.

Highway & Coastal Trail Armoring (Caltrans)

Jan 2016 Surfers’ Beach, Caltrans project

San Mateo County, Caltrans, and Half Moon Bay collaborated on a project constructed in 2016 to protect the highway from erosion at Surfers’ Beach, connect a 400-foot section of the Coastal Trail, and add a stairway down to the beach over the newly installed 175-foot section of rock slope protection.  The Coastal Development Permit for the coastal armoring is temporary, for a 10-year period, to allow time for Caltrans to implement a long-term solution to protect the highway from erosion (such as moving this section of highway).

Harbor Breakwater (US Army Corps of Engineers)

Construction of the Pillar Point Harbor breakwater by the Army Corps 1959-61 dramatically increased the rate of erosion south of the jetty to Medio Creek.  In 2009 the Army Corps, with the Harbor District as local 50% sponsor, initiated the Northern Half Moon Bay Shoreline Improvement Project to determine the feasibility of an Army Corps project to mitigate greatly increased down-coast erosion and harbor sediment buildup.

Seven plus years and over $1 million later, the final report was released in Feb 2017. This table summarizes the design measures analyzed and conclusions. The preferred alternative, estimated to cost $5 million, was to move 150,000 cubic yards of harbor dredged material to Surfers' Beach and southward to the Miramar revetment (figure); however, no Army Corps project is recommended for federal funding due to inadequate cost/benefit ratio.
