Bulkheads

DCG staff have designed a wide variety of bulkheads, both in marine and freshwater environments. Bulkhead types can range from mechanically stabilized earth (MSE) walls to cast-in-place concrete or even steel sheet pile walls.

Lopez Island Gabion Basket Wall

DCG provided engineering for the construction of a gabion basket wall on Lopez Island, Washington. Since a steep slope behind a timber bulkhead was showing significant sloughing, DCG designed a solution with gabion baskets along the slope to stabilize the hillside. Photo taken during construction.

Tulalip Timber Bulkhead

DCG is providing ongoing engineering and regulatory compliance support for the replacement of an existing timber bulkhead at Priest Point, Washington. DCG has provided a unique design with timber pilings and concrete lagging because timber pile installation was significantly simpler at this private residence than the installation of heavier steel members from the shore.

Camano Island HOA Bulkhead

DCG is currently providing structural design and permit compliance support for the replacement of a 340-ft long timber bulkhead that sits at the base of a coastal bluff with 22 homes sitting atop it. Work has begun with a survey, geotechnical investigation, and comparison of wall concepts including concrete, sheet pile, soldier pile, and MSE wall systems. The full scope of work entails developing a design for the wall, obtaining approved permits, and providing construction support. The photo shown here is of the deteriorated timber bulkhead, prior to construction.

Browns Point Vinyl Z-Sheet Bulkhead

DCG provided complete engineering and permitting services for a new concrete bulkhead to be cast against vinyl sheet piles and placed waterward of an existing bulkhead on the cliffs of Browns Point, Washington. Additional support was provided for an aluminum framed retractable boat ramp with FRP grating.
