Abstract

The long-term monitoring of a major beach restoration project on the shore of Seahurst Park in Burien, Washington included 10 years of post-project physical beach monitoring between 2005 and 2015, along with 2 years of pre-project monitoring. Restoration at the park was initiated to remove the failing shore armor, restore natural processes and rebuild the beach profile for the benefit of Pacific salmon and other species and to augment the park visitors’ experience through a more natural beach environment and improved trails. Multiple tools from the Shoreline Monitoring Toolbox were implemented following restoration, however this talk focuses on the application of physical beach monitoring.

Beach topographic data was collected via total station survey in both the south and north park beach restoration phases. Analysis included both profile change observations as well as comprehensive beach surface change analysis from topographic data. Sediment sampling of the upper beach was completed concurrent with beach surveying. Samples were processed for sediment grain size and compared to previous years. Results of ten years of monitoring are discussed along with lessons learned and implications for future monitoring projects.
