Jurisdictional Determination Request
F. JURISDICTIONAL DETERMINATION(JD)TYPE (Select One)
n I am requesting that the Corps provide a preliminary JD for the property identified herein.
A Preliminary Jurisdictional Determination(PJD)provides an indication that there may
be "waters of the United States"or"navigable waters of the United States"on a property.
PJDs are sufficient as the basis for permit decisions. For the purposes of permitting, all
waters and wetlands on the property will be treated as if they are jurisdictional "waters of
the United States". PJDs cannot be appealed(33 C.F.R. 331.2); however, a PJD is
"preliminary"in the sense that an approved JD can be requested at any time. PJDs do
not expire.
0 I am requesting that the Corps provide an approved JD for the property identified herein.
An Approved Jurisdictional Determination(AJD) is a determination that
jurisdictional "waters of the United States"or"navigable waters of the United
States" are either present or absent on a site. An approved JD identifies the limits of
waters on a site determined to be jurisdictional under the Clean Water Act and/or
Rivers and Harbors Act. Approved JDs are sufficient as the basis for permit
decisions. AJDs are appealable (33 C.F.R. 331.2). The results of the AJD will be
posted on the Corps website. A landowner,permit applicant, or other"affected
party" (33 C.F.R. 331.2)who receives an AJD may rely upon the AJD for five years
(subject to certain limited exceptions explained in Regulatory Guidance Letter 05-
02).
I am unclear as to which JD I would like to request and require additional information
to inform my decision.
G. ALL REQUESTS
n Map of Property or Project Area. This Map must clearly depict the boundaries of the
review area.
n Size of Property or Review Area —0.85 acres.
n The property boundary(or review area boundary) is clearly physically marked on the site.

length of each of these features as appropriate.
• Isolated waters, waters that lack a significant nexus to navigable waters, or non-
jurisdictional upland features should be identified as Non-Jurisdictional. Please

"Isolated", "No Significant Nexus", or"Upland Feature"). Please include the acreage

For Preliminary Jurisdictional Determinations:
• Wetland and non-wetland features should not be identified as Jurisdictional, 404,
Waters of the United States, or anything that implies jurisdiction. These features can be

1) The Corps of Engineers believes that there may be jurisdictional aquatic resources in
the review area, and the requestor of this PJD is hereby advised of his or her option
to request and obtain an approved JD (AJD) for that review area based on an
informed decision after having discussed the various types of JDs and their
characteristics and circumstances when they may be appropriate.
2) In any circumstance where a permit applicant obtains an individual permit, or a
Nationwide General Permit (NWP) or other general permit verification requiring "pre-
construction notification" (PCN), or requests verification for a non-reporting NWP or
other general permit, and the permit applicant has not requested an AJD for the
activity, the permit applicant is hereby made aware that: (1)the permit applicant has
elected to seek a permit authorization based on a PJD, which does not make an
official determination of jurisdictional aquatic resources; (2) the applicant has the
option to request an AJD before accepting the terms and conditions of the permit
authorization, and that basing a permit authorization on an AJD could possibly result
in less compensatory mitigation being required or different special conditions; (3)the
applicant has the right to request an individual permit rather than accepting the terms
and conditions of the NWP or other general permit authorization; (4) the applicant can
accept a permit authorization and thereby agree to comply with all the terms and
conditions of that permit, including whatever mitigation requirements the Corps has
determined to be necessary; (5) undertaking any activity in reliance upon the subject
permit authorization without requesting an AJD constitutes the applicant's acceptance
of the use of the PJD; (6) accepting a permit authorization (e.g., signing a proffered
individual permit)or undertaking any activity in reliance on any form of Corps permit
authorization based on a PJD constitutes agreement that all aquatic resources in the
review area affected in any way by that activity will be treated as jurisdictional, and
waives any challenge to such jurisdiction in any administrative or judicial compliance
or enforcement action, or in any administrative appeal or in any Federal court; and (7)
whether the applicant elects to use either an AJD or a PJD, the JD will be processed
as soon as practicable. Further, an AJD, a proffered individual permit (and all terms
and conditions contained therein), or individual permit denial can be administratively
appealed pursuant to 33 C.F.R. Part 331. If, during an administrative appeal, it
becomes appropriate to make an official determination whether geographic
jurisdiction exists over aquatic resources in the review area, or to provide an official
delineation of jurisdictional aquatic resources in the review area, the Corps will
provide an AJD to accomplish that result, as soon as is practicable. This PJD finds
that there "may be"waters of the U.S. and/or that there "may be"navigable waters of
the U.S. on the subject review area, and identifies all aquatic features in the review
area that could be affected by the proposed activity, based on the following
information:

C`A C'A Vegetation is close to undisturbed in species present and their proportions. Lower strata composed of native
species,with non-native invasive species absent or sparse.

species. This may include communities of weedy native species that develop after clear-cutting or clearing or
communities with non-native invasive species present,but not dominant,over a large portion of the expected strata or
communities missing understory but retaining canopy trees.
C`C C`C Vegetation is severely disturbed in terms of species diversity or proportions. Mature canopy is absent or communities
with non-native invasive species dominant over a large portion of expected strata or communities composed of planted
