Maintenance Alert

Santa Ana River Flood Control Channel | Annual Maintenance: Excess Sand Removal from Channel Outlet, Operation of Large Equipment


Large equipment will be used at the Santa Ana River outlet and along Newport Beach areas. Crews will remove excess sand that naturally accumulated in the flood channel outlet area. This is routine maintenance performed annually before the storm season to prevent water flow blockages. This is being done in coordination with the State Lands Commission for State-owned land located at the shoreline.


At the Santa Ana River flood control channel outlet between the cities of Huntington Beach and Newport Beach, west of Pacific Coast Highway.

* See also PDF attached below for maps of location and replenishment area (Between 52nd Street and 40th Street).


  1. Approximately up to 70,000 cubic yards of accumulated sand will be removed from the channel outlet near the shoreline, as allowed through regulatory permits for flood control maintenance. Removing the excess sand minimizes potential flood risks during rain events and also maintains the natural tidal flow with the adjacent Newport Shores marsh area. Removed sand will be visually inspected for notable debris that will be removed prior to placement on beach areas.
  2. In coordination with the City of Newport Beach, crews will transport the removed sand to City beach areas that will benefit most from sand replenishment.

Your safety is the top priority! Large equipment will be used. Please observe all caution signs / barriers and stay a safe distance from the work area.
