Honolulu District's Donald Schlack, the District's subject matter expert for Emergency Power, talks with emergency respone officials at his workstation in the Honolulu District Emergency Operations Center. In response to Hurricane Iselle, the U.S. Army Corps of Engineers, Honolulu District fielded multiple assets to assist the U.S. Coast Guard, Hawaii State Civil Defense, FEMA, and other federal, state, and local agencies. The Honolulu District, working with our local and federal partners, jointly conducted an underwater survey in Hilo Harbor on Aug. 8 and ensured there were no channel obstructions. Based on the successful results of this survey, the Coast Guard reopened Hilo Harbor the same day allowing vessel traffic to safely resume. The District, teaming with the 249th Engineer Battalion - Prime Power, also worked with state and federal officials to assist their efforts in restoring power in affected areas.
