Crescent City Inner Harbor Rehabilitation

Langan provided geotechnical services for the Crescent City Inner Harbor rehabilitation project after it was affected by the tsunami generated from the 2011 earthquake in Japan.  The project consisted of replacing existing steel piles with concrete piles and adding additional concrete piles to support new concrete floating docks, and constructing new foundations for the three gangway landings.In addition to foundation design, we evaluated the stability of harbor slopes for both static and seismic conditions, and have provided recommendations for increasing their stability. The project won the 2016 ACEC California Engineering Excellence Award.
