Low Tide on the Beaches

CGS staff were out collecting data last week at the lowest daytime summer tides.
Field crews and project leads were getting new projects going at the USGS Marine Station on Marrowstone Island (pictured), along a Whidbey Island bluff edge road, at the Birch Bay berm, and at several residential parcels around the region.
We also kicked off a new phase of design work at two of Bellingham’s existing and future waterfront parks.

This study assessed the feasibility of a revolving loan fund, which would finance low-interest loans for residential shoreline projects like hard armor removal, soft-shore stabilization, and elevating or moving homes landward to reduce flooding risk under sea level rise. This study includes a technical report by CGS on the costs of these Shore Friendly actions, which is the most comprehensive regional cost study to-date.

2021 Nearshore Restoration Summit

Register here for three days of presentations hosted by PSEMP, WDFW, and ESRP.

Join CGS’s Jim Johannessen at the 2021 Nearshore Restoration Summit on March 11 at 8:40am PST.  Jim will discuss Puget Sound coastal restoration design considerations for the rest of the 21st century, kicking off day two of the summit.  This virtual conference is put on by the Washington Department of Fish and Wildlife and Estuary and Salmon and Restoration Program to connect nearshore restoration scientists and practitioners through the latest research and future issues for Salish Sea nearshore restoration.

Soft Shore Protection in Skagit County

In 2019, CGS completed the design of this soft shore protection project for at a low-elevation, high wave energy site on Fidalgo Island. The design is intended to mitigate flood risk under for future conditions of sea level rise.

CGS is providing oversight of project construction, which includes the installation of large buried wood and a gravel berm (completed) and planting of native backshore vegetation (coming soon!).

Birch Bay Beach Nourishment

1.6 miles of Birch Bay beach nourishment has begun! On the ground construction started in early January for what is thought to be the largest beach nourishment project in the greater Puget Sound region (210,000 tons)!

This extensive beach nourishment endeavor is intended to create a broad beach backshore and walking trail. The project was first conceived in 1975 by Wolf Bauer. Jim Johannessen of CGS has worked on several stages of this project over the course of its history. CGS was a key beach designer for the consultant team, working for Whatcom County Public Works.

Work is occurring at the south end of the project most evenings through February 15 and will start again after Labor Day continuing northward.
