It isn’t just plastic bags, butts and balloons littering the coast. Dock bumpers, debris booms and sandbags shed plastic, too.
The California Coastal Commission will vote this week on new guidance cities can use in their coastal development plans to reduce plastic in its growing number of forms, whether it's foodware, plastic paint flaking off boats, caution tape swirling in the tide or beached buoys.
San Diego passed an ordinance in 2023 to curb single-use plastics like polystyrene (aka Styrofoam), including foam dock floats, buoys and navigation markers, but things like sandbags and tobacco waste aren’t part of it.
Yet more than 100,000 sandbags were used across the county during a single storm in August 2023. Once made from burlap, most now are plastic; the county says if they can’t be safely reused, or the sand removed and the cover trashed, take them straight to the landfill. .

Less than nine percent of plastic gets recycled in California, causing harm to terrestrial, freshwater, estuarine, and marine ecosystems, not to mention a hefty cleaning bill: California communities spend more than $428 million per year on plastic pollution.
Using the guidance, project reviewers could help reduce the toll from one of the most littered items on earth, cigarette filters — each of which can fragment into as many as 15,000 microfibers — by requiring receptacles in areas where smokers congregate.
Alila Marea, a beach resort in Encinitas, faced stricter permit conditions applied by the commission: keep a smoke-free environment to reduce cigarette litter, install recycling bins and a microfiber laundry filtration system, swap one-time use containers for reusable ones where feasible, and join regional programs that monitor such measures.
In addition to such common trash, the nonprofit Paddle Out Plastic picks up “dock bumpers of all shapes and sizes”; wrappers around piling that falls in the water; chunks of debris booms; straw wattles wrapped in plastic netting, used in erosion control; foam from floating docks; and all types of signs and their protective plastic, which hail from shore and buoy.
Woven plastic sandbags are currently ubiquitous along the coast, trails, roads, and nature preserves, said a letter to the commission. The bags break open and leak plastic “and seem to never be removed by whoever installed them,” it said.
“To our way of thinking burlap or other natural fiber should be substituted universally for woven plastic sandbags.”
Burlap, which is biodegradable, is recommended “when available” by the department of water resources, but polypropylene plastic sandbags are cheaper, more plentiful, and can be stored for years without rotting.
Like other sources of plastic, they also leach toxic chemicals and can have a large impact.
Among the many ways the commission suggests cities can cut down on plastic is by choosing alternative materials. Local coastal plans “can require that outdoor structures, products, and activities prioritize the use of non-plastic materials wherever feasible.”
According to the commission, well over 80 percent of debris found on California beaches is some form of plastic.
