Project Description:
Years of wave related erosion of the Perisama shelf supporting this 30-year old gravity retaining wall were beginning to undermine it. Soil Engineering Construction, Inc., working with the owner and their coastal consultant (HKA) designed, permitted and implemented the installation of a cutoff trench designed to protect the seawall from undermining. For this project, SEC excavated and placed approximately 200 lineal feet of 24" wide, 6' deep cut off trench along the base of an existing seawall to protect three properties.
