Existing tonnages and trends in oceanborne commerce in Humboldt Harbor have been determined, with a finding that the need for navigation improvements is more critical now than anticipated when the project was authorized in 1968 on the basis of projections and findings set forth in the Project Document (H.D. No. 330, 90th Congress, 2d Session). The economics of the project have been completely reevaluated and it is agreed that timely initiation of the work of deepening the North Bay Channels from their existing 30-foot depth to their authorized depth of 35 feet is imperative to efficient and safe operation of the harbor in its accommodation of the larger, deep draft vessels now in use for transocean shipment of logs, lumber, wood pulp, chips and other bulk forest products. Economic transportation, particularly waterborne transportation, is fundamental to maintenance of a competitive timber industry and the economic well-being of the five county tributary area of Humboldt Bay and Harbor.
