Project Manager: Michael Murphy, Emergency Services Coordinator 94325 Moore Street (Courthouse Annex) P.O. Box 746 Gold Beach, OR 97444 FUNDING The strongest winter windstorm in several years came ashore in southwest Oregon on February 7, 2002, resulting in extensive property, vegetation, and electric utility damage as well as widespread loss of electrical service and associated economic losses. The storm’s destructive forces extended through the Coast Range and into the, mid Willamette Valley. On March 12, 2002, President Bush declared a five-county area of Oregon a federal disaster area. This disaster was designated FEMA-1405-DR-OR under the Robert T. Stafford Disaster Relief and Emergency Assistance Act, PL 93-288. Under the declaration, federal funds are provided for the state and affected local governments in the counties of Coos, Curry, Douglas, Lane and Linn to pay 75 percent of the eligible cost for debris removal, emergency services, and restoring damaged public facilities. The declaration also makes cost-shared funding, through the Hazard Mitigation Grant Program (HMGP), available to the state for approved projects that will reduce future disaster losses and resulting costs. Funding for this project was awarded to Curry County through the Hazard Mitigation Grant Program, DR-1405, HMGP#11-99011; Project: Curry County Natural Hazards Mitigation Planning. 1.1. 8 *Executive Summary: Hazard Mitigation Survey Team Report for the Severe Windstorm in Western Oregon, February 7, 2002. Prepared by Oregon Emergency Management and the Federal Emergency Management Agency. ORGANIZATION The Curry County Natural Hazard Mitigation Plan is the collaborative effort of the County, all incorporated cities and communities within the county, rural fire districts, and special districts, to address multi-hazard issues including flood, landslide, severe winter storm, windstorm, wildfire, earthquake, and tsunami. Each participating city and the county have identified specific hazards that impact the community’s residents and infrastructure keeping in mind that there is a considerable transient population in tourism.
