Snohomish Estuary Wetlands Study. Volume I. Summary Report

摘要

This study provides a basis for the environmental evaluation of public interest factors and a factual body of physical, biological, public policy, and land use information for the Snohomish estuary study area, to be used in the environmental evaluation and review of Corps Section 10 and Section 404 permit applications. Wetlands and areas of particular importance or concern in the study area are identified and described. A method for the assessment of the specific and cumulative impacts of proposed permit activities is presented. The study area includes the entire 100-year floodplain of the Snohomish River north of its confluence with Ebey Slough, Everett Harbor, the north shore of Possession Sound including Tulalip Bay and adjacent upland boundaries. Emphasis is on the floodplain and areas under Corps jurisdiction; the upland areas are included because activities there may influence wetlands and floodplain areas. The permit review process as carried out by the Seattle District is described.
