Surfers' Beach Erosion
Construction of the Pillar Point Harbor breakwater in 1960 dramatically increased the rate of erosion south of the jetty, taking away the beach and threatening the highway.
See Surfers' Beach page.
Mirada Rd Armoring in Miramar
Inevitable deterioration of rock slope protection along Mirada Rd from wave action is ongoing. In Jan 2016 placement of supplemental rip-rap boulders ~100 feet south of Medio Ave was done with emergency permit from the Coastal Commission. The County has budgeted $2.6 million in 2016/17 for a longer-term solution for Mirada Rd erosion protection. Dept of Public Works has suggested soil-nail wall covered with sculpted colored shotcrete, or sheet-pile wall.

Coastal Regional Sediment (sand) Management Plans
(CRSMP) are being developed for specific portions of the coast (littoral cells). The program seeks to present ways to restore and preserve beaches, reduce the proliferation of protective shoreline structures, sustain recreation and tourism, enhance public safety and access, restore coastal sandy habitats, and identify cost-effective solutions for restoration of areas impacted by excess sediment.
- Pillar Point to Moss Landing is the extent of the Santa Cruz Littoral Cell CRSMP. The 352-page final plan was released Sept 2015. A 7-page excerpt doc covers just Pillar Point and Surfers' Beach area.
- San Francisco to Pacifica Littoral Cell Coastal Regional Sediment Management Plan is here.
- The Midcoast north of Pillar Point is not included in either of these studies.
