This Washington State Department of Ecology report outlines stormwater erosion and sediment control requirements for large construction projects involving one or more acres of disturbed land in the Puget Sound Basin. It describes best management practices (BMPs) such as covering exposed soil, trapping sediment onsite, and protecting adjacent properties from runoff and sediment. Developers are required to create an erosion and sediment control plan and are financially responsible for its implementation.Open full document
Notes
A Washington State Department of Ecology report summarizing erosion and sediment control requirements for large parcel construction projects involving one acre or more of land disturbance. The report covers best management practices (BMPs) for covering soil, trapping sediment, protecting adjacent properties, controlling other pollutants, and managing construction activities. It also outlines the requirement for a large parcel erosion and sediment control plan and references the NPDES permit program.
