Description This report describes changes in shoreline morphology resulting from the removal of ~800 feet of shoreline armoring from the base of a historic feeder bluff at Edgewater Beach in South Puget Sound near Olympia, Washington. High-resolution, 3D topographic data were collected before and after bulkhead removal using boat-based lidar coupled with ground-based GNSS beach topography and sediment grain-size analysis. The restoration increased effective beach width and large woody debris, improved spawning habitat, and enhanced the sediment budget of the drift cell.
The mission of the Department of Ecology is to protect, preserve, and enhance Washington’s environment. To help us meet that goal, please consider the environment before you print or request a copy.
