California's scour mitigation spans both seismic-zone river crossings and coastal infrastructure exposed to Pacific storm surge, and Caltrans bridges statewide require scour protection engineered for the state's combination of seismic loading and variable coastal-to-inland flow conditions.
GSI treats this as one of several Washouts & Scour Damage issues the state's infrastructure owners regularly face.
Riprap and armor stone for California bridge crossings are sized for site-specific flow conditions ranging from seasonal coastal storm surge to seismic-zone river dynamics. This draws directly on GSI's bridge solutions work.
Grout-filled mattress systems for California infrastructure incorporate seismic performance considerations alongside standard scour protection design. GSI's emergency bridge repair capability supports this step.
Sheet pile and grouted rock protection at California bridge foundations addresses both routine scour and the additional loading seismic events can introduce to already-scoured foundations. This is one application of GSI's broader coastal and bluff stabilization expertise.
GSI often considers water infrastructure alongside this work when scoping California projects.
Engineered for California's conditions. GSI's California scour mitigation integrates seismic performance into standard scour protection design — a combined requirement most other states' scour work doesn't share. GSI's transportation infrastructure and engineers experience backs this approach.
Design/build delivery. The same organization designs and installs — removing the coordination overhead of separate design and construction firms.
Caltrans specification compliance. Project documentation and field methods comply with state DOT standards starting with the earliest documentation.
