Project Description: 

The Crest residential development sits at the crest of the coastal bluff located immediately down coast of downtown Capitola.  The Owners plan to do a condominium conversion demanded various site improvements to mitigate the detrimental effects of coastal processes.  Soil Engineering Construction, Inc., in concert with the Owners geotechnical consultant, developed a plan to design, permit and construct the following: an underpinning system incorporating deeply drilled, reinforced concrete underpinning piers, a slope stabilization system incorporating tieback restrained shear pins with a connecting grade beam, a sea cave fill program incorporating protective anchors to allow the work to proceed safely, and a cut off wall to prevent unmining and the placement of a structural fill.

• Deeply drilled underpinning piers

• Tieback restrained shear pins

• Grade Beam

• Sea Cave infill with protective anchors

• Placement of structural fill
