Jurisdictional Determinations

Jurisdictional Determinations (JDs) are tools used by the U.S. Army Corps of Engineers to help implement Section 404 of the Clean Water Act and Sections 9 and 10 of the Rivers and Harbors Act of 1899 and define our limits of geographic jurisdiction. â€‹

Delineation Concurrence: Concurrence with a wetland delineation is a written notification from the Corps concurring, not concurring, or commenting on the wetland boundaries delineated on a property. Under this request, the Corps will not address the jurisdictional status of the wetlands on the property, only the boundaries of the resources within the review area.​

Preliminary Jurisdictional Determination (PJD):  A PJD is a nonbinding written indication that there may be waters of the United States, including wetlands, on a parcel or indications of the approximate location(s) of waters of the United States or wetlands on a parcel. For purposes of computation of impacts and compensatory mitigation requirements a permit decision made based on a PJD will treat all waters and wetlands in the review area as if they are jurisdictional waters of the U.S. PJDs are advisory in nature and may not be appealed.​

Approved Jurisdictional Determination (AJD): An AJD is an official Corps determination that jurisdictional waters of the United States or navigable waters of the United States, or both, are either present or absent on the property. An approved jurisdictional determination precisely identifies the limits of those waters on the project site determined to be jurisdictional under the Clean Water Act or Rivers and Harbors Act. Approved jurisdictional determinations can be relied upon by the affected party for a period of five years. An approved jurisdictional determination may be appealed through the Corps’ administrative appeal process.
