British Columbia Stabilized Construction Entrances and Trackout Control
Environmental Management Act, Municipal ESC Bylaws, and Salmon Habitat Protection
British Columbia's water defines the province, from the Fraser River and the salmon streams of the Lower Mainland and Vancouver Island to the Pacific coast, the Okanagan, and the mountain rivers of the Interior. Salmon-bearing waters run through the middle of the province's fastest-growing communities, and the region's long, wet winters send heavy runoff through active construction sites. On this ground, keeping sediment on the job site and off public roads is a core compliance duty, and a stabilized construction entrance is one of the first controls installed and inspected.
British Columbia Environmental Regulation
British Columbia controls construction discharges under the Environmental Management Act, which regulates the introduction of waste, including sediment, into the environment, and under the Water Sustainability Act, which governs work in and about a stream. A project must comply with these provincial laws and, in most cases, with the more detailed erosion and sediment control requirements set by the local government. British Columbia projects also sit under the federal Fisheries Act, which is enforced actively in the province because so much construction happens near salmon habitat, so letting sediment reach a fish-bearing stream can carry serious federal consequences on top of provincial and municipal enforcement.
Municipal ESC Bylaws and Qualified Professionals
Most of British Columbia's erosion and sediment control requirements are set and enforced by municipalities, and the bylaws across Metro Vancouver are among the strictest in the country. Municipalities including Vancouver, Surrey, Coquitlam, Burnaby, and the District of North Vancouver require an erosion and sediment control plan and permit before construction, often prepared and monitored by a qualified environmental professional, with turbidity limits at the point of discharge and enhanced controls during the wet season. Site access measures must specifically address soil tracking and sediment run-off, which puts the construction entrance at the centre of compliance. Standard construction details across the Lower Mainland follow the Master Municipal Construction Documents (MMCD).
The Aggregate Construction Entrance and Its Limits
British Columbia guidance describes the traditional construction entrance as a pad of coarse crushed aggregate placed over a geotextile fabric at every site exit, sized and built to knock sediment loose from tires, with runoff directed to a sediment control such as a trap or a treatment system.
The weakness of the aggregate pad is maintenance, and British Columbia's wet climate makes it worse. Through the Lower Mainland's rainy season, the stone quickly fills with saturated mud, loses its ability to clean tires, and must be topped up or replaced, while any material tracked onto the road has to be removed before it washes into a storm drain. When the stone pad alone is not enough, a wheel wash sprays tires with pressurized water and drains to a sediment trap, adding water handling and cleanout. Each traditional option carries a recurring cost and a maintenance cycle that a durable manufactured entrance can avoid.
FODS as a Compliant Construction Entrance in British Columbia
British Columbia evaluates a construction entrance on whether it performs the required function, removing sediment from tires before vehicles reach the road, and the operator specifies the chosen practice in the erosion and sediment control plan. FODS Trackout Control Mats can be named directly in that plan as the site's stabilized construction entrance, satisfying the same purpose as the aggregate pad while removing the loose stone and the heavy maintenance the traditional design depends on. On sites near salmon streams, where a qualified professional is monitoring turbidity and the Fisheries Act is in play, an entrance that reliably keeps sediment out of the storm system is a direct compliance advantage.
FODS Trackout Control System
The FODS Trackout Control System is a reusable, manufactured construction entrance made of high-density polyethylene mats with a pyramid-shaped surface that works like the rough edges of crushed stone. As vehicles pass, the pyramids deform the tires and open the tread so sediment breaks loose and collects in the voids between the pyramids, clear of the tires. Each mat measures about 3.7 metres by 2.1 metres, and the modular design lets contractors build the entrance to fit the site. On high-traffic projects the system has reduced street sweeping by 59 percent compared with aggregate.
FODS performs consistently in wet conditions, which matters through a British Columbia winter, and unlike a rock pad it does not saturate and fail as the rain sets in. The mats install over any substrate without excavation and can be relocated quickly as work advances, which suits phased site development, transit, and highway work. Because the system uses no loose stone, there is nothing to lodge in dual tires or migrate onto active roadways, and maintenance is a quick pass with a skid steer broom, a powered sweeper, or a FODS shovel. With a service life of more than ten years, the same mats can be reused across projects, which shifts the cost of a construction entrance from a recurring expense to a one-time investment.
Risks of Vehicle Trackout on Roadways
Safety is a primary concern wherever construction traffic meets a public road. Aggregate exits deposit stone and debris onto pavement, creating hazards for drivers and workers, and loose rock can lodge between dual tires and be thrown at speed. Wheel washes add the burden of supplying and containing water. FODS uses a rockless, water-free technique to clean tires and does not carry the same risk of injury or liability as aggregate entrances. The mats are durable and reusable across many projects, which reduces the environmental impact tied to aggregate production, hauling, and disposal. On British Columbia sites that drain to the Fraser, the coastal inlets, or any of the province's salmon streams, keeping stone and sediment off the road also helps keep it out of the water and out of fish habitat protected under the Fisheries Act.
