Mount St. Helens, Washington Feasibility Report & Environmental Impact Statement. Volume 1: Main Report

Abstract

The eruption of Mount St. Helens, which began in the spring of 1980, resulted in the movement of sediment creating a threat of flooding and navigation disruption in southwestern Washington. President Reagan recognized that the Federal Government was spending millions of dollars for emergency action and would continue responding to any emergency which threatened life and property. Thus he requested, through a Memorandum to the Secretary of Defense, that the Corps of Engineers prepare alternative strategies for handling the projected movement of sediment. The strategies were to address the continuing problems of flood hazards and potential disruptions to navigation based upon engineering feasibility, economic merit and environmental sensitivity. The report, "A Comprehensive Plan for Responding to the Long-term Threat Created by the Eruption of Mount St. Helens, Washington," was forwarded to the President in November 1983. The plan evaluated five alternative strategies for sediment control and analyzed six alternative outlets for stabilizing the level of Spirit Lake. In transmitting the Comprehensive Plan report, the Assistant Secretary of the Army recommended finding a permanent solution to the sediment control problem that could be forwarded for congressional authorization and funding. This report responds to that recommendation. Key elements of the Comprehensive Plan are summarized later in this document. Further refinement of the plan presented in this report will occur during the Continued Planning and Engineering (CP&E). In addition, analysis and design of other alternatives will continue.
