As a part of the Beach Nourishment Science Sprint, a new final report (Lambert & Chamberlin 2023) was recently published! CGS was contracted by WDFW in this first of a series of “Science Sprint” research efforts where state and federal scientists are providing direction and expert opinions of critical nearshore resources management issues.

Coastal Geologic Services' work by Avery Maverick and Jim Johannessen on assessing sea level rise vulnerability in Puget Sound was just published in the Journal of Sustainability! This was a collaborative effort with Washington Sea Grant (Dr. Ian Miller, lead) where we developed a framework for calculating a sea level rise vulnerability score for every coastal parcel in Puget Sound, totaling 111,239 parcels. The assessment incorporated coastal flooding and erosion to quantify the impacts to habitats and infrastructure. Our results suggest that adaptation actions directed at a relatively small number of specific parcels could yield significant reductions in vulnerability in Puget Sound. Additionally, our results were coupled with a social vulnerability index, developed in tandem with a group from NOAA’s National Centers for Coastal Ocean Science.

A great day of vegetation planting and invasive species removal at Little Squalicum Estuary!

CGS staff joined over 200 volunteers this Saturday, including Bellingham Mayor Seth Fleetwood and US Representative Rick Larsen, in the Martin Luther King Jr. Day of Service Community Work Party at Little Squalicum Park. Volunteers planted over 4,600 estuary and upland plants throughout the park and removed 24 cubic yards of invasive vegetation! CGS has been a part of the Little Squalicum Estuary habitat enhancement project from the beginning over 15 years ago, including work on the conceptual design, funding support, final project design, and construction oversight. Once completed, the project will provide important rearing habitat for ESA-listed Chinook salmon from the Nooksack River, as well as benefits to other species including steelhead, chum salmon, coho salmon, surf smelt, and sand lance.

Thanks to the City of Bellingham, Nooksack Salmon Enhancement Association, and many other partners for organizing a wonderful community event!

Up until 1853, the Coast Salish peoples used the estuary at Maritime Heritage Park as a canoe landing and camp for fishing and gathering. From 1853 to 1874 Henry Roeder and Russell Peabody ran a sawmill at the mouth of Whatcom Creek. Then from the early 1900’s until the 1970’s the estuary was filled with 20 feet of garbage and dredge spoils. After decades of restoration actives including the installation of over 100,000 native plants and invasive vegetation removal, in August 2020, Lummi tribal fisherman harvested salmon from Whatcom Creek for the first time in 100 years! Whatcom Creek currently supports coho, chum, and Chinook salmon, as well as Steelhead trout along 4 miles of accessible salmon habitat downstream of Lake Whatcom.

CGS’s coastal geologist, Avery Maverick volunteered with NSEA - Nooksack Salmon Enhancement Association and City of Bellingham, Washington - Government at the park this last weekend in one of their ongoing work party events. Awesome to see salmon in the creek during the event!

Construction for Little Squalicum will commence this summer following a design created by CGS! A large new estuary will be built along Squalicum Creek in Western Bellingham close to the mouth of the Nooksack River to replace the lost estuary and nearshore habitats. Construction will be conducted by Glacier Environmental who was recently awarded a contract by the City of Bellingham. Also, the Port of Bellingham will be starting construction of a new beach area east of the park based on conceptual plans designed by CGS in 2008. Come check out the City's project open house this Wednesday, May 25th between 6:00 to 8:00 PM at Bellingham Technical College, located 3028 Lindberg Avenue. (https://cob.org/event/lse-open-house)

Another Bellingham favorite: Boulevard Park!

Scroll through these photos to go back in time and see what this site looked like 20 years ago.

CGS was part of the restoration of Boulevard Park which began in 2013. Working with , CGS completed a beach restoration design that created safe beach access, made the park more resilient to storms, and restored beach habitat for forage fish.

As you can see in some of the before photos (particularly the third one), the old shoreline had a few issues!

Another bulkhead removal and beach restoration project is underway in Similk Bay in Skagit County! The goals of this project are to restore surf smelt spawning and marine riparian vegetation areas. 

CGS did the design for this project which is managed by the program.
