Weaverling Spit Restoration Phase 3, Fidalgo Bay

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.

High resolution mapping in action

This is a sample 3D model created for a recent project using aerial imagery from a drone (UAV or UAS). CGS uses drone imagery and RTK GPS technology to produce high-quality models and topographic surfaces anchored in geographic space.
