Seawall Repair on Private Property, Incorporating Public Access Stairs & Walkway

Project Description & Challenges:

This is a Seawall repair on private property incorporating public access stairs and walkway to the beach. The entirety of the work was performed from private property through a side yard access point that is less than 6 feet wide.

Techniques & Materials Utilized:

The finished project includes more than 30 grouted tiebacks in bedrock, more than 30 Chance Helical tiebacks in terrace soils, thousands of pounds of corrosion resistant reinforcing steel, hundreds of cubic yards of structural and art-rockrock carved shotcrete and a custom art-rock concealed door separating the private property from the public access walkway. The seawall is founded more than four feet below the tide line of the Pacific Ocean. The primary challenge in constructing this project is it’s location at the edge of and within the water; combined with the tiny access point and the need to maintain public access adjacent and around the work at one of the most popular surf and coastal access points in Santa Cruz.

Pacific Helix Products Used:

Chance SS series tiebacks and terminations.
