This article provides a description of the ongoing problem of derelict docks, and a record of docks the community has been left to deal with in past years. Derelict docks have been a growing problem in the last few years, and we expect more docks will wash up on our shores in the future. Climatologists are predicting an increase in the frequency and severity of winter storms, and many of the docks in the Salish Sea will reach their end of life in the coming years. In this article we will describe what has happened with the four docks that have washed ashore recently on Mayne Island. We hope these examples will encourage dock owners to maintain and properly dispose of dock infrastructure, and raise awareness about the current lack of government support for derelict dock cleanup.

Piggott Bay Beach July 2017

The first derelict dock we’ll look at washed up on Piggott Bay Beach sometime in early 2017. Its origin is unknown. It was composed of large open styrofoam blocks with a concrete cap. Each time the tide came in the dock would rub back and forth on the beach, spewing more styrofoam pellets. Piggott Bay is notable on Mayne Island as a place where microplastics have built up. (See our previous article here for more info.) Thankfully, this dock was right beside the access at Piggott Bay Beach and volunteers were able to deconstruct the dock and load it onto the Recycling Society’s truck for transport to Hartland Landfill. Special thanks to the many volunteers, the Recycling Society for providing transport, and the CRD for covering the dump fee.

Campbell Bay Beach January 2019

The second derelict dock we’ll look at washed up at Campbell Bay Beach in the winter of 2019. Like the previous dock, it was made of exposed styrofoam on the bottom, but glued to a ribbed concrete top laced with rebar. It was also grinding on the beach and by the time volunteers started cleanup, styrofoam pellets were thick across the top of the south half of the beach. The rebar reinforcement caused us trouble, and if it wasn’t for staff and equipment from the Mayne Island Fire Department we would not have been able to deconstruct the dock. Hauling bags of wet styrofoam up the steep path was also a challenge. Special thanks on this one to the many volunteers, Michael Dunn and Ryan Boeur especially for putting in long shifts, the MI Fire Department, Home Hardware for tool loan, and Dan Hafting for waiving transport fee to the dump.

Campbell Bay Beach February 2020

The third dock we’ll look at was another section of dock from the same origin as the previous one. This was a case of failure to properly maintain the dock, and it was disheartening for those who had helped clean up the first section the year before. Volunteers were able to flip this section over, allowing access to the styrofoam without having to cut the rebar. Special thanks to Jesse and Rachel Jones for trying to prevent the need for cleanup in the first place, Meg Iredale for coordinating the cleanup, and the many volunteers including the 2nd Mayne Island Scouts. Also to the owner of the dock for having the courage to show up and help with the cleanup, and Mayne Island Garbage for covering disposal costs.

St. John Point – January 2022

The fourth dock we took apart was washed up on the shore of St. John Point and reported to us in early January of 2022. This dock was made of two sections, each approximately 2m x 3m, connected by a pressure treated top rail. The top and sides were capped with concrete, with exposed styrofoam on the bottom and one side. About 35% of the styrofoam had already dispersed into the ocean when we got to it. We organized a community cleanup with eight volunteers and were able to demolish the dock with grinders, sledge hammers, and wire cutters. Fortunately there was no rebar reinforcement in this dock. The styrofoam pile was transported by boat in two trips to Spud Point where it was transported by vehicle to Hartland Landfill. A big thank you to all the hardworking community volunteers who helped out, as well as a special thanks to Lucas from Life Aquatic Marine Endeavors for tool loan, Lance and Laura for assisting with boat transport, and Mayne Island Garbage for again covering the costs of transport and dump fee to the landfill.

Piggot Bay Beach – 2024

The fifth dock that was found and removed was first reported by a Piggott Bay resident Patti Bacchus, who posted on Facebook for advice on what to do. The response from the community was swift – special thanks to Michael Ball from Mayne Island Towing and Recovery, and two islanders Martin Renaud and Pat Roberts for working to pull the cement-encased Styrofoam off the beach and on to the road. From there, community members Meg Iredale and Ryan Boeur separated the concrete from the Styrofoam using sledgehammers and reciprocal saws, and from there the Styrofoam blocks were picked up by Mayne Island Recycling Centre volunteer Grant Buday and Conservancy staff Justine Apostolopoulos. Thanks to the MI Recycling Centre, the Styrofoam will be brought to an Ocean Legacy recycling depot for upcycling, and the concrete will be transported to Hartland Landfill after the 2024 Annual Beach Clean-Up.

Campbell Point – present day

The sixth dock we’ll look at is still sitting on the shoreline of Campbell Point—a physical symbol of the lack of government ownership on the issue of derelict docks. This one is too large for our community volunteers to handle, though the nearby property owners have done a great job of minimizing the spread of styrofoam until a permanent solution can be found. This dock is about 12 metres (40′) long and made of styrofoam compartments encased on all sides but the top. The two end compartments were spewing styrofoam until they were cleaned up by the property owners. Efforts to have the Coast Guard or Transport Canada take action to remove the dock have failed. Both organizations say it’s not their responsibility, which leaves the question, whose is it? Eventually this dock will be carried to a new location during a winter storm. Possibly Campbell Bay Beach? Perhaps knocking other docks loose along the way?

Recommendations for current or potential dock owners

We want to provide a friendly reminder to all dock and boat owners on Mayne Island to please maintain your docks and boats. Failure to maintain and properly dispose of aging docks and boats can lead to the situations described above. Accidents can and do happen but let’s do our best to prevent them.

  • Before building your own dock, approach neighbours about sharing existing structures if they exist.
  • Complete regular inspections of your docks and boats, especially in winter during storm season. If you are absent for long periods of time, hire a local to make your checks for you.
  • To hire a local company offering marine infrastructure maintenance services, contact Life Aquatic Marine Endeavors at 250-222-0477
  • Label your boat and dock with your name and phone number so people can call you if things break loose.
  • Have a plan for end of life disposal. Before deciding to install a dock or purchase a property with a dock, make sure you understand the process and costs of getting rid of the dock responsibly when the time comes.
  • Regularly replace any worn lines and connections.
  • Before installing a dock, consult your local nature conservancy for the locations of eelgrass and bull kelp beds

Reef Bay has been picking up a lot of debris from the New West pier fire, clumps of creosote-covered logs with huge spikes through them. I can’t believe booms were not put in place to catch this poisonous garbage before it came down the river. Most of the time we can clean up small debris and put it in our own garbage, should we be calling the Conservancy if we get something we can’t handle?

    Rob Underhill · November 3, 2020 at 1:01 pm

    The best group to contact depends on what it is. If you see a boat floating that looks uncontrolled call the Coast Guard at 1-800-567-5111. If you see a “hazard to navigation” call Transport Canada. If large debris is washed up on shore there is no official group to contact but yes please contact the Conservancy. We can’t promise we can do anything about it since we don’t have any resources for cleanup but we may be able to organize a volunteer cleanup in certain circumstances. At a minimum we will try to document it to help describe this ongoing problem.
