Commission approves buried pin‑pier wall to protect Opal Cliff Drive condominium

The Capitola Planning Commission on July 17 unanimously approved a Coastal Development Permit and Conditional Use Permit for a buried pin‑pier wall system to protect a 12‑unit condominium at 4820 Opal Cliff Drive after staff, the applicant and an outside geotechnical reviewer resolved technical comments. Staff said the proposal responds to a significant erosion event tied to 2022–2023 storms that left the bluff in proximity to the building and that the building predates the Coastal Act; staff and the applicant agreed that the structure qualifies as protection for existing development under the local coastal program. The approved design calls for 28 drilled piers at 4‑foot centers down roughly 47 feet to bedrock, tied by a cast‑in‑place grade beam, and 18 tensioned tiebacks at about 25 degrees and 58 feet in length. Cotton Shires, a contracted geotechnical reviewer, requested deeper piers and steeper tieback angles; the applicant revised the design in response. Staff also consulted Coastal Commission staff, which requested the pier locations be shifted farther from the building; the applicant moved the piers to roughly 9.5 feet from the building as requested. An HOA board member, John Kazam, told the commission the association had worked through consultants, contractor selection and a special homeowner vote to raise funds and that the building is in “imminent danger” of compromise from further bluff collapse. Kazam said the association initially sought an emergency CDP but was redirected to the regular process because of timing and project complexity. Applicant and staff presentations described the finished wall as largely buried with minimal visibility above grade, and staff said contractor means, methods and phasing details were provided to address staging near the bluff edge; contractor staging is proposed primarily within the condominium parking lot rather than public street staging. Conditions require a final landscape plan and additional construction sequencing details to reduce vegetation loss and manage equipment movement. Commissioners asked about equipment size and staging; staff noted the drill rig would have roughly an 8‑foot track width and would be moved in a sequenced pattern with clustered drilling to minimize movement along the work area. Staff said Coastal Commission staff had been kept informed and that the applicant had addressed the Coastal Commission’s technical memo. A motion to approve application 02/50231 carried unanimously on roll call (Commissioner Howard yes, Commissioner Que aye, Chair Esty aye). The applicant and HOA representatives said they plan to pursue longer‑term regional solutions in coordination with adjacent property owners and the Coastal Commission but regard the pin‑pier wall as the practicable near‑term protection for the existing structure.
