What is Erosion Control? 

Erosion prevention and sediment control (EPSC) is a way to prevent soil and sediment form washing away during construction and land development. This process includes both temporary and permanent best management practices, known as BMPs. The main goal is to reduce the amount of soil and other pollutants that enter rivers, wetlands, and drainage systems. By doing this, we protect our natural resources and lessen the impact of construction on nearby areas. 

Why is This Important?

The City of Salem requires an erosion control permit for any construction or development project that disturbs more than 1,000 square feet of land. These rules are in place to protect our natural resources and ensure that development is responsible. This information is important for anyone planning a construction project, no matter how big or small. Understanding these requirements helps you follow City, State, and Federal laws. 

When is an Erosion Control Permit Required? 

You need a City-issued Erosion Control Permit if your project disturbs 1,000 square feet or more of land. Common projects that require this permit include new home construction, commercial or multi-family developments, additions, accessory structures, and retaining walls.

You need a City-issued Erosion Control Permit and a Department of Environmental Quality (DEQ) 1200-C Permit if your project disturbs one-acre or more of land. Common projects that require this permit include subdivisions or large commercial and multi-family developments. 

When is an Erosion Control Permit Not Required?

You do not need an erosion control permit for the following activities:

  • Normal home gardening or landscaping, unless:
    • You are working within 50 feet of a waterway and disturbing more than 1,000 square feet.
    • The land has a steep slope (more than 25 percent).
  • Projects that disturb less than 1,000 square feet of soil.
  • Interior work inside an existing building.
  • Activities that do not disturb the ground at all.
  • Projects covered under a 1200-CA General Permit from the Oregon Department of Environmental Quality.
  • Activities that count as farm use or accepted farming practices under Oregon law.
  • Mining activities with permits from the Oregon Department of Geology and Mineral Industries.
  • Routine maintenance of gravel roads, road shoulders, paths, parking lots, and storage yards.
  • Routine care of sports fields or playgrounds that already have grass or permanent curbing.

Project Size Determines the Process

Your application process depends on how much land your project will disturb.

Projects Disturbing Less Than 10,000 Sq Ft
Projects Disturbing 10,000 Sq Ft or More
Projects Disturbing One Acre or More

No matter what size your project is, you are responsible for erosion control on site. You can download the Erosion Sediment Control Site Plan Review checklist to make sure your project meets all requirements for erosion control.
