2011 Tsunami at the Port of Brookings, Oregon

On March 11, 2011, we received a request from the Port of Brookings, Oregon, to assist in the response, already initiated by the Port Director, Mr. Ted Fitzgerald, to the effects of Japan’s devastating earthquake and destructive tsunami surges.

As wave surges had begun arriving and entering the Port of Brookings harbor in mid-morning of the 11th, Ted and members of his crew had already been working down at the docks for hours. Due to their early response, most of the commercial recreational boat owners had been notified, and many had been able to get their vessels out of the harbor and harm’s way.

Though it could have been much worse, serious damage nevertheless occurred that day at the Port of Brookings, the Port just southward at Crescent City, CA, and other Oregon Ports north of Brookings (e.g. Gold Beach, Port Orford and Bandon).

In addition to the destruction of numerous docks and piles, and some vessels, an estimated 30,000 cubic yards of sediment and debris had within the harbor of the Port of Brookings accumulated as a result of the tsunami wave surges.

Response had to be immediate. FEMA & OEM were of tremendous assistance.

Since 2009 we have entered into projects to assist a number of other south coast projects at various ports, providing engineering planning and design, permitting, landslide revetments repair, dredge and disposal planning, sediment planning, sampling, evaluation and characterization, submerged aquatic vegetation survey, avoidance and mitigation , equipment evaluation and specification, provided assistance in obtaining federal and state grants, etc.
