Anchor QEA is assisting Island County with roadway drainage analysis, design, wetland delineation, impacts assessment, mitigation design, and permitting as part of a 1.3-mile-long road improvement project.  The project is located adjacent to the historic Dugualla Bay tidal estuary (now modified to a freshwater marsh) near Whidbey Island Naval Air Station.  The project will make some adjustments to the roadway horizontal and vertical alignment, widen its two travel lanes to 12 feet, expand its paved shoulders, and construct walls where needed to conform to topographic constraints and to maintain slope stability.  Stormwater improvements will include roadway drainage separation and collection, conveyance, treatment, and dispersed outfall, along with upslope run-on drainage collection and bypass.  Beyond stormwater services, Anchor QEA completed wetland and stream delineations along with wildlife habitat review, reported those results, and prepared a wetland mitigation plan that meets the requirements of the U.S. Army Corps of Engineers (Corps), Washington State Department of Ecology (Ecology), and the County Critical Areas Ordinance.  The wetland mitigation design (currently in progress) incorporates the use of treated stormwater and natural upland drainages to enhance wetland hydrology and revegetate the Dugualla Lake shoreline area (a prior tidal estuary habitat) that has been altered by agricultural practices.  Anchor QEA also prepared a Biological Assessment (BA) as part of an Endangered Species Act (ESA) analysis for the project and is providing assistance with environmental permitting to gain required construction approvals.  Construction is currently planned beginning in 2009.
