Overview: The Walla Walla District Regulatory Program

The Walla Walla District, Corps of Engineers is responsible for administering the Regulatory Program in the State of Idaho. The Regulatory office processes permit applications for work that occurs in “waters of the United States” that are regulated by the Corps.

Regulated activities within our jurisdiction require a permit from the Corps. The majority of Regulatory Program authority falls under two laws:

  1. Section 10 of the Rivers and Harbors Act (1890 & 1899)
  2. Section 404 of the Clean Water Act

Examples of areas that may be within Corps jurisdiction are:

  • Marshes and swamps
  • Streams, creeks, and rivers
  • Ponds and lakes
  • Wetlands, including seasonally-saturated forested and non-forested wetlands

Examples of work activities that require a permit include:

  • Dredging of waterways
  • Bank stabilization
  • Recreational ponds and lakes
  • Construction of piers, docks, marinas, fleeting areas, boat ramps, roads
  • Residential and commercial developments
  • Utility lines
  • Mining activities
