The project consisted of widening a section of State Highway 1 in Carmel, California. Prior to our involvement in the project, protected Cypress trees were identified near the proposed retaining wall. Cal Engineering & Geology was hired as a subconsultant to the project civil engineer to design the retaining wall. Following a site visit and meetings with the civil engineer, CE&G suggested construction of a pier and grade beam supported segmental block retaining wall to limit excavation and potential damage to the Cypress trees. Excavation at the site was limited to the pile excavations which were observed by an arborist and the grade beam was constructed at grade to avoid damage to the root system of the Cypress trees. The grade beam was designed to resist vertical loads from the segmental block wall and horizontal loads from earth pressure acting on the retained side of the grade beam. CE&G also designed a sheet pile wall which was used for temporary shoring for a portion of the project, to limit excavation near a high pressure gas line.
