Jim Johannessen, Owner and Principal Geologist at CGS, recently presented to over 250 attendees at the Restore America’s Estuaries National Living Shorelines Technology Transfer Workshop in Oakland, CA. The presentation, titled “Living Shorelines/Soft Shore Protection Design and Implementation in Puget Sound”, detailed the ins and outs of soft shore protection: what it means, how it interacts with the coastal environment, its ecological benefits and design methods, and how it has been successfully applied by CGS on dynamic coasts throughout Puget Sound region.
In fall of 2017, Coastal Geologic Services completed Phase 3 of the Weaverling Spit Restoration project for the Samish Indian Nation. Weaverling Spit is located on the west shore of the Fidalgo Bay Aquatic Reserve, across from Marchs Point in Skagit County. The spit contains documented forage fish spawning beaches for surf smelt, which are an important food source for many marine mammals, birds, and fish — particularly salmon.
Over 200 cubic yards of rock and fill debris were removed from the rockery armor at the Samish RV parking area, and soft shore beach nourishment (sediment import) along with large wood installations were placed along the regraded upper beach to improve beach stability and forage fish spawning habitat.
This project occurred in three phases: Phase 1 was completed in 2009, Phase 2 was completed in 2012, and Phase 3 concluded in September 2017 after 2 years of work. CGS completed mapping, assessment, design, and monitoring, and assisted with planning and construction oversight for all three phases.
