Baltimore District

Overview

The identification and location of jurisdictional Waters of the United States, including wetlands regulated by the U.S. Army Corps of Engineers under Section 404 of the Clean Water Act and Sections 9 and 10 of the Rivers and Harbors Act, is determined through a process known as a Jurisdictional Determination (JD). The Corps uses a multi-parameter approach defined in the Corps's Wetland Delineation Manual, dated January 1987, and supplemental guidance (including Regional Supplements) when making wetland determinations. View graphics generally depicting the extent of Section 10 and Section 404 jurisdiction

Regional Supplements

Regional Supplements to the U.S. Army Corps of Engineers Wetland Delineation Manual are part of a nationwide effort to address regional wetland characteristics and improve the accuracy and efficiency of wetland-delineation procedures. Regional differences in climate, geology, soils, hydrology, plant and animal communities, and other factors are important to the identification and functioning of wetlands. These supplements were developed by wetland delineation experts from state and federal agencies and academia with experience within this area. Where differences in the two documents occur, the Regional Supplement takes precedence over the Corps Manual.

The Baltimore District is currently using or will in the near future implement three Regional Supplements:

1. Atlantic and Gulf Coastal Plain Supplement

2. Eastern Mountains and Piedmont Supplement

3. Northcentral and Northeast Supplement


National Wetland Plant List

The 2016 National Wetland Plant List (NWPL) was published in the federal register April 18, 2016. NWPL is used to determine whether the hydrophytic vegetation parameter is met when conducting wetland determinations under the Clean Water Act and the Wetland Conservation Provisions of the Food Security Act. NWPL became effective May 1, 2016. Always reference this wetland plant list on any wetland delineation/determination forms.

 

Requesting a Jurisdictional Determination

A property owner or interest may request a jurisdictional determination or verification of delineation from the Corps of Engineers. The final determination of whether an area is waters of the United States, including jurisdictional wetlands, and whether the activity requires a permit must be made by a Corps District Office.
