Erosion Prevention Planning and Design Manual

The City of West Linn places a high value on the conservation of natural resources. Construction activities without proper erosion and sediment control protection can contribute large amounts of sediment and other pollutants to streams, rivers, wetlands and ponds. Construction can also be harmful to trees, including the trunk, canopy and roots. In partnership with the cities of Gladstone, Happy Valley, Lake Oswego, Milwaukie, Oregon City, Wilsonville, Oak Lodge Sanitary District and Clean Water Services, an Erosion Prevention Planning and Design manual was created to assist in guiding developers and contractors in proper erosion and sediment control protection.
