Construction: erosion and sediment control inspection and maintenance

Erosion and sediment control inspection and maintenance

ESC measures require ongoing attention to ensure integrity and performance. ESC inspections should take place, at minimum, during installation, after rainfall events, and at the critical inspection points discussed in the Pre-construction: communication, inspection plan, and utilities coordination (section).

At these inspections, keep an eye out for accumulated sediment, worn materials, compliance with the project's staging plan, and potential failure points.

Soil, sand and minerals washed from land into water, usually after rain. They pile up in reservoirs, rivers and harbors, destroying fish-nesting areas and holes of water animals and cloud the water so that needed sunlight might not reach aquatic plans. Careless farming, mining and building activities will expose sediment materials, allowing them to be washed off the land after rainfalls.
