Understood
. I suggest checking out the JD educational materials for the Corps' Regulatory Request System (i.e., our new electronic submittal system launched earlier this year). See the RRS jurisdiction page at:
https://rrs.usace.army.mil/rrs/home/jurisdiction
Read through the Q&As on that page and you should see how the Corps is prioritizing delineation-only reviews ahead of JD options.
In particular, check out the Q&A for: "Can the USACE provide written assurance regarding the location of regulated waters on my project site?"
Here's the answer they provide (emphasis mine):
Bottom line: Written assurance is provided as part of the permit application review process and generally doesn't/shouldn't involve a JD.
Agreed. Except you definitely shouldn't need a JD to establish jurisdictional boundaries early or obtain Corps concurrence. Note that one of the RRS submittal options is "Submit an Aquatic Resource Delineation Report and Aquatic Resource Inventory." This option was included in the RRS to steer applicants toward delineation-only verifications instead of JDs. Delineation review/approval is all that should be needed for most permit applications.
As mentioned, you're completely within your rights to request a JD. An AJD does, after all, provide five years of legal assurance regarding a resource's jurisdictional/non-jurisdictional status, which could be especially useful for large/complex/controversial projects where you're afraid of WOTUS definitions changing prior to completion of the permit process (but even that's not 100% assured).
In any case, from what I've shared above, it should hopefully at least be clear that JDs are not the "only appropriate method of boundary acceptance"
.
Hope that helps. I'm also happy to hash this out via DM or phone if you like...sometimes simply chatting can be the best way to work through all the little questions/nuances.
