Streambank Stabilization/
Instream Habitats

Streambank stabilization helps protect public and private property from losses due to erosion and bank failures. RR’s bank stabilization and in-stream habitat design/build services are the best in the industry.


Flood control levees need protection from erosive flows. Natural streambanks, though never static, can be relatively stable. Perturbations in the watershed can cause bank erosion which can lead to:

  • Loss of valuable private property
  • Sedimentation of important salmon and steelhead spawning gravels
  • De-stabilization of stream morphology, causing additional bank erosion until a new equilibrium is established

Streambank instability has multiple causes, including urbanization, channel modifications, irrigation water transport, effluent water transport, as well as natural causes such as flood flows, animal activities and wildfires. In addition, flood control levees on major rivers often require specialized reinforcement to protect them from erosion caused by high river flows.
