Jurisdictional determination (JD)
A jurisdictional determination is a U.S. Army Corps of Engineers document stating whether wetlands or waters on a site are regulated under the Clean Water Act. An approved JD is a formal, appealable finding, while a preliminary JD treats the features as potentially jurisdictional. Securing one clarifies what can be filled, what needs a Section 404 permit, and how much land is truly buildable.
