DEPARTMENT OF THE ARMY NATIONWIDE PERMIT VERIFICATION
Dear Mr. McKinney:
I am responding to your request (Corps File No. SPL-2018-00491-LOB) for a Department of
the Army permit for the La Quinta/Dune Palms Road Bridge Replacement of Low Water
Crossing Project located along Dune Palms Road over the Coachella Valley Storm Water
Channel (CVSC) north of Highway 11 and south of Blackhawk Way/Westward Ho Drive in the
City of La Quinta within Riverside County, California (Latitude 33.710833°, Longitude -
116.277777°). (Figures 1-2)
Because implementation of this project would result in a discharge of dredged and/or fill
material into waters of the United States, a Department of the Army permit is required pursuant
to section 404 of the Clean Water Act (33 U.S.C. 1344; 33 C.F.R. parts 323 and 330). I have
determined your proposed project, if constructed as described in your application, would comply
with Nationwide Permit (NWP) 14 – Linear Transportation Projects and NWP 33- Temporary
Construction, Access, and Dewatering. Specifically, you are authorized (as shown on the
enclosed figures) to conduct the following regulated activities:
1. Discharge permanent fill material into approximately 0.02 acre (20 linear feet) of non-
wetland waters of the U.S., including the discharge of 300 cubic yards of concrete for
the installation of 4 bridge columns within the CVSC;
2. Temporarily discharge dredged or fill material into approximately 0.72 acre of non-
wetland waters of the U.S. for:
a.A bypass road of approximately 0.35 acre that would be removed once the
bridge is finalized; and
b. Dredge approximately 0.24 acre for construction access, grading, and
excavation.
3. Temporary impact 0.01 acre of wetland waters of the U.S. to remove a storm drain
outlet.
For this NWP verification letter to be valid, you must comply with all of the terms and
conditions in Enclosure 1. Furthermore, you must comply with the non-discretionary Special
Conditions listed below:
- 2 -
Special Conditions:
1. This NWP verification is contingent upon the issuance of a section 401 Water Quality
Certification (WQC) from the Regional Water Quality Control Board (RWQCB). The
Permittee shall abide by the terms and conditions of the section 401 WQC. The Permittee
shall submit the section 401 WQC to the Corps Regulatory Division (preferably via email)
within two weeks of receipt from the issuing state agency. The Permittee shall not proceed
with work within waters of the United States until receiving an e-mail or other written
notification from Corps Regulatory Division acknowledging the section 401 WQC has been
received, reviewed, and determined to be acceptable. If the RWQCB fails to act on a valid
request for certification within two months after receipt of a complete application, please
notify the Corps Regulatory Division so we may consider whether a waiver of water quality
certification has been obtained.
2. Within 45 calendar days of completion of authorized work in waters of the U.S., the
Permittee shall submit to the Corps Regulatory Division a post-project implementation
memorandum including the following information:
a.Date(s) work within waters of the U.S. was initiated and completed;
b.Summary of compliance status with each special condition of this permit (including
any noncompliance that previously occurred or is currently occurring and corrective
actions taken or proposed to achieve compliance);
c.Color photographs (including map of photo points) taken at the project site before and
after construction for those aspects directly associated with permanent impacts to
waters of the U.S. such that the extent of authorized fills can be verified;
d. One copy of "as built" drawings for the entire project. Electronic submittal (Adobe
PDF format) is preferred. All sheets must be signed, dated, and to-scale. If
submitting paper copies, sheets must be no larger than 11 x 17 inches; and
e.Signed Certification of Compliance (attached as part of this permit package).
3. Pursuant to 36 C.F.R. section 800.13, in the event of any discoveries during construction of
either human remains, archeological deposits, or any other type of historic property, the
Permittee shall notify the Corps' Archaeology staff (Danielle Storey at 213-452-3845 OR
Meg McDonald at 213-452-3849) and Corps Regulatory Division (Luis O. Betancourt-
Massanet at 213-452-3375 or Stephanie Hall at 213-452-3410) within 24 hours. The
Permittee shall immediately suspend all work in any area(s) within 100 feet of where
potential cultural resources are discovered. The Permittee shall not resume construction in
the area surrounding the potential cultural resources until the Corps Regulatory Division re-
authorizes project construction, per 36 C.F.R. section 800.13.
4. The Permittee shall place orange safety fencing during construction to restrict entry to the
parcel where site P-33-16950 (CA-RIV-8835) is located. Additionally, ground disturbing
- 3 -
activities in the Area of Direct Impact in the site vicinity shall be observed by archaeological
and Native American monitors
5. The Permittee shall discharge only clean construction materials in and along waters of the
U.S. The Permittee shall ensure no debris, soil, silt, sand, sawdust, rubbish, cement or
concrete washings thereof, oil or petroleum products, from construction shall be allowed to
enter into or placed where it may be washed by rainfall or runoff into waters of the United
States. Upon completion of the project authorized herein, any and all excess material or
debris shall be completely removed from the work area and disposed of in an appropriate
upland site.
6. No later than one month following completion of authorized work in waters of the U.S., the
Permittee shall ensure all sites within waters of the U.S. subject to authorized, temporary
impacts are restored to pre-project alignments, elevation contours, and conditions to the
maximum extent practicable to ensure expeditious resumption of aquatic resource functions.
In addition, within 4 months of initial occurrence of project impacts to waters of the U.S., the
Permittee shall hydroseed, where possible, the disturbed portions of the earthen stream banks
and bottom and floodplain, as appropriate, with native, non-invasive species, as appropriate
to the affected areas, to reduce the potential for erosion. The Permittee shall submit the
proposed native planting palette for review and approval by the Corps Regulatory Division at
least 30 days prior to initiation of construction. The Permittee shall ensure the affected areas
(disturbed stream channel bottoms and banks and hydroseeded/replanted areas) are
maintained and monitored annually for a period of three years after completing the native
seeding activities, such that less than 10 percent (absolute cover) of the drainages disturbed
by the project are vegetated by non-native and invasive plant species. For each project
drainage feature, the Permittee shall submit to the Corps Regulatory Division a memorandum
by December 31th after completion of the minimum three-year maintenance and monitoring
period. The memo shall indicate for each project crossing/aquatic impact area, when
temporary construction areas were re-contoured to pre-construction conditions, when native
seeding was completed, the species and percent cover (absolute) of invasive and/or non-
invasive plant species that occur onsite each year prior to treatment, and when and how
many/the extent of invasive and/or non-invasive plant species that were removed each year.
This verification is valid through March 18, 2022. If on March 18, 2022, you have
commenced or are under contract to commence the permitted activity, you will have an
additional twelve (12) months to complete the activity under the present NWP terms and
conditions. However, if I discover noncompliance or unauthorized activities associated with the
permitted activity, I may request the use of discretionary authority in accordance with procedures
in 33 C.F.R. § 330.4(e) and 33 C.F.R. §§ 330.5(c) or (d) to modify, suspend, or revoke this
specific verification at an earlier date. Additionally, at the national level, the Chief of Engineers,
any time prior to March 18, 2022, may choose to modify, suspend, or revoke the nationwide use
- 4 -
of a NWP after following procedures set forth in 33 CFR § 330.5. It is incumbent upon you to
comply with all of the terms and conditions of this NWP verification and to remain informed of
any change to the NWPs.
A NWP does not grant any property rights or exclusive privileges. Additionally, it does not
authorize any injury to the property, rights of others, nor does it authorize interference with any
existing or proposed Federal project. Furthermore, it does not obviate the need to obtain other
Federal, state, or local authorizations required by law.
Thank you for participating in the regulatory program. If you have any questions, please
contact Luis Betancourt-Massanet at 213-452-3845 or via e-mail at

Enclosure 1: NATIONWIDE PERMIT NUMBER(S) NWP 14 Linear Transportation Projects and NWP
33 Temporary Construction, Access, and Dewatering
1. Nationwide Permit(s) NWP 14 Linear Transportation Projects and NWP 33 Temporary
Construction, Access, and Dewatering Terms:
14. Linear Transportation Projects. Activities required for crossings of waters of the United States associated
with the construction, expansion, modification, or improvement of linear transportation projects (e.g., roads,
highways, railways, trails, airport runways, and taxiways) in waters of the United States. For linear
transportation projects in non-tidal waters, the discharge cannot cause the loss of greater than 1/2-acre of waters
of the United States. For linear transportation projects in tidal waters, the discharge cannot cause the loss of
greater than 1/3-acre of waters of the United States. Any stream channel modification, including bank
stabilization, is limited to the minimum necessary to construct or protect the linear transportation project; such
modifications must be in the immediate vicinity of the project. This NWP also authorizes temporary structures,
fills, and work, including the use of temporary mats, necessary to construct the linear transportation project.
Appropriate measures must be taken to maintain normal downstream flows and minimize flooding to the
maximum extent practicable, when temporary structures, work, and discharges, including cofferdams, are
necessary for construction activities, access fills, or dewatering of construction sites. Temporary fills must
consist of materials, and be placed in a manner, that will not be eroded by expected high flows. Temporary fills
must be removed in their entirety and the affected areas returned to pre-construction elevations. The areas
affected by temporary fills must be revegetated, as appropriate. This NWP cannot be used to authorize non-
linear features commonly associated with transportation projects, such as vehicle maintenance or storage
buildings, parking lots, train stations, or aircraft hangars. Notification: The permittee must submit a pre-
construction notification to the district engineer prior to commencing the activity if: (1) the loss of waters of the
United States exceeds 1/10-acre; or (2) there is a discharge in a special aquatic site, including wetlands. (See
general condition 32.) (Authorities: Sections 10 and 404) Note 1: For linear transportation projects crossing a
single waterbody more than one time at separate and distant locations, or multiple waterbodies at separate and
distant locations, each crossing is considered a single and complete project for purposes of NWP authorization.
Linear transportation projects must comply with 33 CFR 330.6(d). Note 2: Some discharges for the
construction of farm roads or forest roads, or temporary roads for moving mining equipment, may qualify for an
exemption under section 404(f) of the Clean Water Act (see 33 CFR 323.4). Note 3: For NWP 14 activities that
require pre-construction notification, the PCN must include any other NWP(s), regional general permit(s), or
individual permit(s) used or intended to be used to authorize any part of the proposed project or any related
activity, including other separate and distant crossings that require Department of the Army authorization but do
not require pre-construction notification (see paragraph (b) of general condition 32). The district engineer will
evaluate the PCN in accordance with Section D, ¿District Engineer¿s Decision.¿ The district engineer may
require mitigation to ensure that the authorized activity results in no more than minimal individual and
cumulative adverse environmental effects (see general condition 23).
33. Temporary Construction, Access, and Dewatering. Temporary structures, work, and discharges, including
cofferdams, necessary for construction activities or access fills or dewatering of construction sites, provided that
the associated primary activity is authorized by the Corps of Engineers or the U.S. Coast Guard. This NWP also
authorizes temporary structures, work, and discharges, including cofferdams, necessary for construction
activities not otherwise subject to the Corps or U.S. Coast Guard permit requirements. Appropriate measures
must be taken to maintain near normal downstream flows and to minimize flooding. Fill must consist of
materials, and be placed in a manner, that will not be eroded by expected high flows. The use of dredged
material may be allowed if the district engineer determines that it will not cause more than minimal adverse
environmental effects. Following completion of construction, temporary fill must be entirely removed to an area
that has no waters of the United States, dredged material must be returned to its original location, and the
affected areas must be restored to preconstruction elevations. The affected areas must also be revegetated, as
appropriate. This permit does not authorize the use of cofferdams to dewater wetlands or other aquatic areas to
change their use. Structures left in place after construction is completed require a separate section 10 permit if
located in navigable waters of the United States. (See 33 CFR part 322.) Notification: The permittee must
submit a pre-construction notification to the district engineer prior to commencing the activity if the activity is
conducted in navigable waters of the United States (i.e., section 10 waters) (see general condition 32). The
preconstruction notification must include a restoration plan showing how all temporary fills and structures will
be removed and the area restored to pre-project conditions. (Authorities: Sections 10 and 404)
2. General Conditions: The following general conditions must be followed in order for any authorization by
an NWP to be valid:
1. Navigation. (a) No activity may cause more than a minimal adverse effect on navigation.
(b) Any safety lights and signals prescribed by the U.S. Coast Guard, through regulations or otherwise,
must be installed and maintained at the permittee's expense on authorized facilities in navigable waters of the
United States.
(c) The permittee understands and agrees that, if future operations by the United States require the
removal, relocation, or other alteration, of the structure or work herein authorized, or if, in the opinion of the
Secretary of the Army or his authorized representative, said structure or work shall cause unreasonable
obstruction to the free navigation of the navigable waters, the permittee will be required, upon due notice from
the Corps of Engineers, to remove, relocate, or alter the structural work or obstructions caused thereb y, without
expense to the United States. No claim shall be made against the United States on account of any such removal
or alteration.
2. Aquatic Life Movements. No activity may substantially disrupt the necessary life cycle movements of
those species of aquatic life indigenous to the waterbody, including those species that normally migrate through
the area, unless the activity's primary purpose is to impound water. All permanent and temporary crossings of
waterbodies shall be suitably culverted, bridged, or otherwise designed and constructed to maintain low flows to
sustain the movement of those aquatic species. If a bottomless culvert cannot be used, then the crossing should
be designed and constructed to minimize adverse effects to aquatic life movements.
3. Spawning Areas. Activities in spawning areas during spawning seasons must be avoided to the
maximum extent practicable. Activities that result in the physical destruction (e.g., through excavation, fill, or
downstream smothering by substantial turbidity) of an important spawning area are not authorized.
4. Migratory Bird Breeding Areas. Activities in waters of the United States that serve as breeding areas
for migratory birds must be avoided to the maximum extent practicable.
5. Shellfish Beds. No activity may occur in areas of concentrated shellfish populations, unless the
activity is directly related to a shellfish harvesting activity authorized by NWPs 4 and 48, or is a shellfish
seeding or habitat restoration activity authorized by NWP 27.
6. Suitable Material. No activity may use unsuitable material (e.g., trash, debris, car bodies, asphalt,
etc.). Material used for construction or discharged must be free from toxic pollutants in toxic amounts (see
section 307 of the Clean Water Act).
7. Water Supply Intakes. No activity may occur in the proximity of a public water supply intake, except
where the activity is for the repair or improvement of public water supply intake structures or adjacent bank
stabilization.
8. Adverse Effects From Impoundments. If the activity creates an impoundment of water, adverse
effects to the aquatic system due to accelerating the passage of water, and/or restricting its flow must be
minimized to the maximum extent practicable.
9. Management of Water Flows. To the maximum extent practicable, the pre-construction course,
condition, capacity, and location of open waters must be maintained for each activity, including stream
channelization, storm water management activities, and temporary and permanent road crossings, except as
provided below. The activity must be constructed to withstand expected high flows. The activity must not
restrict or impede the passage of normal or high flows, unless the primary purpose of the activity is to impound
water or manage high flows. The activity may alter the pre-construction course, condition, capacity, and
location of open waters if it benefits the aquatic environment (e.g., stream restoration or relocation activities).
10. Fills Within 100-Year Floodplains. The activity must comply with applicable FEMA-approved state
or local floodplain management requirements.
11. Equipment. Heavy equipment working in wetlands or mudflats must be placed on mats, or other
measures must be taken to minimize soil disturbance.
12. Soil Erosion and Sediment Controls. Appropriate soil erosion and sediment controls must be used
and maintained in effective operating condition during construction, and all exposed soil and other fills, as well
as any work below the ordinary high water mark or high tide line, must be permanently stabilized at the earliest
practicable date. Permittees are encouraged to perform work within waters of the United States during periods
of low-flow or no-flow, or during low tides.
13. Removal of Temporary Fills. Temporary fills must be removed in their entirety and the affected
areas returned to pre-construction elevations. The affected areas must be revegetated, as appropriate.
14. Proper Maintenance. Any authorized structure or fill shall be properly maintained, including
maintenance to ensure public safety and compliance with applicable NWP general conditions, as well as any
activity-specific conditions added by the district engineer to an NWP authorization.
15. Single and Complete Project. The activity must be a single and complete project. The same NWP
cannot be used more than once for the same single and complete project.
16. Wild and Scenic Rivers. (a) No NWP activity may occur in a component of the National Wild and
Scenic River System, or in a river officially designated by Congress as a “study river” for possible inclusion in
the system while the river is in an official study status, unless the appropriate Federal agency with direct
management responsibility for such river, has determined in writing that the proposed activity will not adversely
affect the Wild and Scenic River designation or study status.
(b) If a proposed NWP activity will occur in a component of the National Wild and Scenic River
System, or in a river officially designated by Congress as a “study river” for possible inclusion in the system
while the river is in an official study status, the permittee must submit a pre-construction notification (see
general condition 32). The district engineer will coordinate the PCN with the Federal agency with direct
management responsibility for that river. The permittee shall not begin the NWP activity until notified by the
district engineer that the Federal agency with direct management responsibility for that river has determined in
writing that the proposed NWP activity will not adversely affect the Wild and Scenic River designation or study
status.
(c) Information on Wild and Scenic Rivers may be obtained from the appropriate Federal land
management agency responsible for the designated Wild and Scenic River or study river (e.g., National Park
Service, U.S. Forest Service, Bureau of Land Management, U.S. Fish and Wildlife Service). Information on
these rivers is also available at: http://www.rivers.gov/.
17. Tribal Rights. No NWP activity may cause more than minimal adverse effects on tribal rights
(including treaty rights), protected tribal resources, or tribal lands.
18. Endangered Species. (a) No activity is authorized under any NWP which is likely to directly or
indirectly jeopardize the continued existence of a threatened or endangered species or a species proposed for
such designation, as identified under the Federal Endangered Species Act (ESA), or which will directly or
indirectly destroy or adversely modify the critical habitat of such species. No activity is authorized under any
NWP which “may affect” a listed species or critical habitat, unless ESA section 7 consultation addressing the
effects of the proposed activity has been completed. Direct effects are the immediate effects on listed species
and critical habitat caused by the NWP activity. Indirect effects are those effects on listed species and critical
habitat that are caused by the NWP activity and are later in time, but still are reasonably certain to occur.
(b) Federal agencies should follow their own procedures for complying with the requirements of the
ESA. If pre-construction notification is required for the proposed activity, the Federal permittee must provide
the district engineer with the appropriate documentation to demonstrate compliance with those requirements.
The district engineer will verify that the appropriate documentation has been submitted. If the appropriate
documentation has not been submitted, additional ESA section 7 consultation may be necessary for the activity
and the respective federal agency would be responsible for fulfilling its obligation under section 7 of the ESA.
(c) Non-federal permittees must submit a pre-construction notification to the district engineer if any
listed species or designated critical habitat might be affected or is in the vicinity of the activity, or if the activity
is located in designated critical habitat, and shall not begin work on the activity until notified by the district
engineer that the requirements of the ESA have been satisfied and that the activity is authorized. For activities
that might affect Federally-listed endangered or threatened species or designated critical habitat, the pre-
construction notification must include the name(s) of the endangered or threatened species that might be
affected by the proposed activity or that utilize the designated critical habitat that might be affected by the
proposed activity. The district engineer will determine whether the proposed activity “may affect” or will have
“no effect” to listed species and designated critical habitat and will notify the non-Federal applicant of the
Corps’ determination within 45 days of receipt of a complete pre-construction notification. In cases where the
non-Federal applicant has identified listed species or critical habitat that might be affected or is in the vicinity of
the activity, and has so notified the Corps, the applicant shall not begin work until the Corps has provided
notification that the proposed activity will have “no effect” on listed species or critical habitat, or until ESA
section 7 consultation has been completed. If the non-Federal applicant has not heard back from the Corps
within 45 days, the applicant must still wait for notification from the Corps.
(d) As a result of formal or informal consultation with the FWS or NMFS the district engineer may add
species-specific permit conditions to the NWPs.
(e) Authorization of an activity by an NWP does not authorize the “take” of a threatened or endangered
species as defined under the ESA. In the absence of separate authorization (e.g., an ESA Section 10 Permit, a
Biological Opinion with “incidental take” provisions, etc.) from the FWS or the NMFS, the Endangered Species
Act prohibits any person subject to the jurisdiction of the United States to take a listed species, where "take"
means to harass, harm, pursue, hunt, shoot, wound, kill, trap, capture, or collect, or to attempt to engage in any
such conduct. The word “harm” in the definition of “take'' means an act which actually kills or injures wildlife.
Such an act may include significant habitat modification or degradation where it actually kills or injures wildlife
by significantly impairing essential behavioral patterns, including breeding, feeding or sheltering.
(f) If the non-federal permittee has a valid ESA section 10(a)(1)(B) incidental take permit with an
approved Habitat Conservation Plan for a project or a group of projects that includes the proposed NWP
activity, the non-federal applicant should provide a copy of that ESA section 10(a)(1)(B) permit with the PCN
required by paragraph (c) of this general condition. The district engineer will coordinate with the agency that
issued the ESA section 10(a)(1)(B) permit to determine whether the proposed NWP activity and the associated
incidental take were considered in the internal ESA section 7 consultation conducted for the ESA section
10(a)(1)(B) permit. If that coordination results in concurrence from the agency that the proposed NWP activity
and the associated incidental take were considered in the internal ESA section 7 consultation for the ESA
section 10(a)(1)(B) permit, the district engineer does not need to conduct a separate ESA section 7 consultation
for the proposed NWP activity. The district engineer will notify the non-federal applicant within 45 days of
receipt of a complete pre-construction notification whether the ESA section 10(a)(1)(B) permit covers the
proposed NWP activity or whether additional ESA section 7 consultation is required.
(g) Information on the location of threatened and endangered species and their critical habitat can be
obtained directly from the offices of the FWS and NMFS or their world wide web pages at http://www.fws.gov/
or http://www.fws.gov/ipac and http://www.nmfs.noaa.gov/pr/species/esa/ respectively.
19. Migratory Birds and Bald and Golden Eagles. The permittee is responsible for ensuring their action
complies with the Migratory Bird Treaty Act and the Bald and Golden Eagle Protection Act. The permittee is
responsible for contacting appropriate local office of the U.S. Fish and Wildlife Service to determine applicable
measures to reduce impacts to migratory birds or eagles, including whether “incidental take” permits are
necessary and available under the Migratory Bird Treaty Act or Bald and Golden Eagle Protection Act for a
particular activity.
20. Historic Properties. (a) In cases where the district engineer determines that the activity may have the
potential to cause effects to properties listed, or eligible for listing, in the National Register of Historic Places,
the activity is not authorized, until the requirements of Section 106 of the National Historic Preservation Act
(NHPA) have been satisfied.
(b) Federal permittees should follow their own procedures for complying with the requirements of
section 106 of the National Historic Preservation Act. If pre-construction notification is required for the
proposed NWP activity, the Federal permittee must provide the district engineer with the appropriate
documentation to demonstrate compliance with those requirements. The district engineer will verify that the
appropriate documentation has been submitted. If the appropriate documentation is not submitted, then
additional consultation under section 106 may be necessary. The respective federal agency is responsible for
fulfilling its obligation to comply with section 106.
(c) Non-federal permittees must submit a pre-construction notification to the district engineer if the
NWP activity might have the potential to cause effects to any historic properties listed on, determined to be
eligible for listing on, or potentially eligible for listing on the National Register of Historic Places, including
previously unidentified properties. For such activities, the pre-construction notification must state which
historic properties might have the potential to be affected by the proposed NWP activity or include a vicinity
map indicating the location of the historic properties or the potential for the presence of historic properties.
Assistance regarding information on the location of, or potential for, the presence of historic properties can be
sought from the State Historic Preservation Officer, Tribal Historic Preservation Officer, or designated tribal
representative, as appropriate, and the National Register of Historic Places (see 33 CFR 330.4(g)). When
reviewing pre-construction notifications, district engineers will comply with the current procedures for
addressing the requirements of section 106 of the National Historic Preservation Act. The district engineer shall
make a reasonable and good faith effort to carry out appropriate identification efforts, which may include
background research, consultation, oral history interviews, sample field investigation, and field survey. Based
on the information submitted in the PCN and these identification efforts, the district engineer shall determine
whether the proposed NWP activity has the potential to cause effects on the historic properties. Section 106
consultation is not required when the district engineer determines that the activity does not have the potential to
cause effects on historic properties (see 36 CFR 800.3(a)). Section 106 consultation is required when the
district engineer determines that the activity has the potential to cause effects on historic properties. The district
engineer will conduct consultation with consulting parties identified under 36 CFR 800.2(c) when he or she
makes any of the following effect determinations for the purposes of section 106 of the NHPA: no historic
properties affected, no adverse effect, or adverse effect. Where the non-Federal applicant has identified historic
properties on which the activity might have the potential to cause effects and so notified the Corps, the non-
Federal applicant shall not begin the activity until notified by the district engineer either that the activity has no
potential to cause effects to historic properties or that NHPA section 106 consultation has been completed.
(d) For non-federal permittees, the district engineer will notify the prospective permittee within 45 days
of receipt of a complete pre-construction notification whether NHPA section 106 consultation is required. If
NHPA section 106 consultation is required, the district engineer will notify the non-Federal applicant that he or
she cannot begin the activity until section 106 consultation is completed. If the non-Federal applicant has not
heard back from the Corps within 45 days, the applicant must still wait for notification from the Corps.
(e) Prospective permittees should be aware that section 110k of the NHPA (54 U.S.C. 306113) prevents
the Corps from granting a permit or other assistance to an applicant who, with intent to avoid the requirements
of section 106 of the NHPA, has intentionally significantly adversely affected a historic property to which the
permit would relate, or having legal power to prevent it, allowed such significant adverse effect to occur, unless
the Corps, after consultation with the Advisory Council on Historic Preservation (ACHP), determines that
circumstances justify granting such assistance despite the adverse effect created or permitted by the applicant.
If circumstances justify granting the assistance, the Corps is required to notify the ACHP and provide
documentation specifying the circumstances, the degree of damage to the integrity of any historic properties
affected, and proposed mitigation. This documentation must include any views obtained from the applicant,
SHPO/THPO, appropriate Indian tribes if the undertaking occurs on or affects historic properties on tribal lands
or affects properties of interest to those tribes, and other parties known to have a legitimate interest in the
impacts to the permitted activity on historic properties.
21. Discovery of Previously Unknown Remains and Artifacts. If you discover any previously unknown
historic, cultural or archeological remains and artifacts while accomplishing the activity authorized by this
permit, you must immediately notify the district engineer of what you have found, and to the maximum extent
practicable, avoid construction activities that may affect the remains and artifacts until the required coordination
has been completed. The district engineer will initiate the Federal, Tribal, and state coordination required to
determine if the items or remains warrant a recovery effort or if the site is eligible for listing in the National
Register of Historic Places.
22. Designated Critical Resource Waters. Critical resource waters include, NOAA-managed marine
sanctuaries and marine monuments, and National Estuarine Research Reserves. The district engineer may
designate, after notice and opportunity for public comment, additional waters officially designated by a state as
having particular environmental or ecological significance, such as outstanding national resource waters or state
natural heritage sites. The district engineer may also designate additional critical resource waters after notice
and opportunity for public comment.
(a) Discharges of dredged or fill material into waters of the United States are not authorized by NWPs 7,
12, 14, 16, 17, 21, 29, 31, 35, 39, 40, 42, 43, 44, 49, 50, 51, and 52 for any activity within, or directly affecting,
critical resource waters, including wetlands adjacent to such waters.
(b) For NWPs 3, 8, 10, 13, 15, 18, 19, 22, 23, 25, 27, 28, 30, 33, 34, 36, 37, 38, and 54, notification is
required in accordance with general condition 32, for any activity proposed in the designated critical resource
waters including wetlands adjacent to those waters. The district engineer may authorize activities under these
NWPs only after it is determined that the impacts to the critical resource waters will be no more than minimal.
23. Mitigation. The district engineer will consider the following factors when determining appropriate
and practicable mitigation necessary to ensure that the individual and cumulative adverse environmental effects
are no more than minimal:
(a) The activity must be designed and constructed to avoid and minimize adverse effects, both temporary
and permanent, to waters of the United States to the maximum extent practicable at the project site (i.e., on site).
(b) Mitigation in all its forms (avoiding, minimizing, rectifying, reducing, or compensating for resource
losses) will be required to the extent necessary to ensure that the individual and cumulative adverse
environmental effects are no more than minimal.
(c) Compensatory mitigation at a minimum one-for-one ratio will be required for all wetland losses that
exceed 1/10-acre and require pre-construction notification, unless the district engineer determines in writing that
either some other form of mitigation would be more environmentally appropriate or the adverse environmental
effects of the proposed activity are no more than minimal, and provides an activity-specific waiver of this
requirement. For wetland losses of 1/10-acre or less that require pre-construction notification, the district
engineer may determine on a case-by-case basis that compensatory mitigation is required to ensure that the
activity results in only minimal adverse environmental effects.
(d) For losses of streams or other open waters that require pre-construction notification, the district
engineer may require compensatory mitigation to ensure that the activity results in no more than minimal
adverse environmental effects. Compensatory mitigation for losses of streams should be provided, if
practicable, through stream rehabilitation, enhancement, or preservation, since streams are difficult-to-replace
resources (see 33 CFR 332.3(e)(3)).
(e) Compensatory mitigation plans for NWP activities in or near streams or other open waters will
normally include a requirement for the restoration or enhancement, maintenance, and legal protection (e.g.,
conservation easements) of riparian areas next to open waters. In some cases, the restoration or
maintenance/protection of riparian areas may be the only compensatory mitigation required. Restored riparian
areas should consist of native species. The width of the required riparian area will address documented water
quality or aquatic habitat loss concerns. Normally, the riparian area will be 25 to 50 feet wide on each side of
the stream, but the district engineer may require slightly wider riparian areas to address documented water
quality or habitat loss concerns. If it is not possible to restore or maintain/protect a riparian area on both sides of
a stream, or if the waterbody is a lake or coastal waters, then restoring or maintaining/protecting a riparian area
along a single bank or shoreline may be sufficient. Where both wetlands and open waters exist on the project
site, the district engineer will determine the appropriate compensatory mitigation (e.g., riparian ar eas and/or
wetlands compensation) based on what is best for the aquatic environment on a watershed basis. In cases where
riparian areas are determined to be the most appropriate form of minimization or compensatory mitigation, the
district engineer may waive or reduce the requirement to provide wetland compensatory mitigation for wetland
losses.
(f) Compensatory mitigation projects provided to offset losses of aquatic resources must comply with
the applicable provisions of 33 CFR part 332.
(1) The prospective permittee is responsible for proposing an appropriate compensatory mitigation
option if compensatory mitigation is necessary to ensure that the activity results in no more than minimal
adverse environmental effects. For the NWPs, the preferred mechanism for providing compensatory mitigation
is mitigation bank credits or in-lieu fee program credits (see 33 CFR 332.3(b)(2) and (3)). However, if an
appropriate number and type of mitigation bank or in-lieu credits are not available at the time the PCN is
submitted to the district engineer, the district engineer may approve the use of permittee-responsible mitigation.
(2) The amount of compensatory mitigation required by the district engineer must be sufficient to ensure
that the authorized activity results in no more than minimal individual and cumulative adverse environmental
effects (see 33 CFR 330.1(e)(3)). (See also 33 CFR 332.3(f)).
(3) Since the likelihood of success is greater and the impacts to potentially valuable uplands are reduced,
aquatic resource restoration should be the first compensatory mitigation option considered for permittee-
responsible mitigation.
(4) If permittee-responsible mitigation is the proposed option, the prospective permittee is responsible
for submitting a mitigation plan. A conceptual or detailed mitigation plan may be used by the district engineer
to make the decision on the NWP verification request, but a final mitigation plan that addresses the applicable
requirements of 33 CFR 332.4(c)(2) through (14) must be approved by the district engineer before the permittee
begins work in waters of the United States, unless the district engineer determines that prior approval of the
final mitigation plan is not practicable or not necessary to ensure timely completion of the required
compensatory mitigation (see 33 CFR 332.3(k)(3)).
(5) If mitigation bank or in-lieu fee program credits are the proposed option, the mitigation plan only
needs to address the baseline conditions at the impact site and the number of credits to be provided.
(6) Compensatory mitigation requirements (e.g., resource type and amount to be provided as
compensatory mitigation, site protection, ecological performance standards, monitoring requirements) may be
addressed through conditions added to the NWP authorization, instead of components of a compensatory
mitigation plan (see 33 CFR 332.4(c)(1)(ii)).
(g) Compensatory mitigation will not be used to increase the acreage losses allowed by the acreage
limits of the NWPs. For example, if an NWP has an acreage limit of 1/2-acre, it cannot be used to authorize any
NWP activity resulting in the loss of greater than 1/2-acre of waters of the United States, even if compensatory
mitigation is provided that replaces or restores some of the lost waters. However, compensatory mitigation can
and should be used, as necessary, to ensure that an NWP activity already meeting the established acreage limits
also satisfies the no more than minimal impact requirement for the NWPs.
(h) Permittees may propose the use of mitigation banks, in-lieu fee programs, or permittee-responsible
mitigation. When developing a compensatory mitigation proposal, the permittee must consider appropriate and
practicable options consistent with the framework at 33 CFR 332.3(b). For activities resulting in the loss of
marine or estuarine resources, permittee-responsible mitigation may be environmentally preferable if there are
no mitigation banks or in-lieu fee programs in the area that have marine or estuarine credits available for sale or
transfer to the permittee. For permittee-responsible mitigation, the special conditions of the NWP verification
must clearly indicate the party or parties responsible for the implementation and performance of the
compensatory mitigation project, and, if required, its long-term management.
(i) Where certain functions and services of waters of the United States are permanently adversely
affected by a regulated activity, such as discharges of dredged or fill material into waters of the United States
that will convert a forested or scrub-shrub wetland to a herbaceous wetland in a permanently maintained utility
line right-of-way, mitigation may be required to reduce the adverse environmental effects of the activity to the
no more than minimal level.
24. Safety of Impoundment Structures. To ensure that all impoundment structures are safely designed,
the district engineer may require non-Federal applicants to demonstrate that the structures comply with
established state dam safety criteria or have been designed by qualified persons. The district engineer may also
require documentation that the design has been independently reviewed by similarly qualified persons, and
appropriate modifications made to ensure safety.
25. Water Quality. Where States and authorized Tribes, or EPA where applicable, have not previously
certified compliance of an NWP with CWA section 401, individual 401 Water Quality Certification must be
obtained or waived (see 33 CFR 330.4(c)). The district engineer or State or Tribe may require additional water
quality management measures to ensure that the authorized activity does not result in more than minimal
degradation of water quality.
26. Coastal Zone Management. In coastal states where an NWP has not previously received a state
coastal zone management consistency concurrence, an individual state coastal zone management consistency
concurrence must be obtained, or a presumption of concurrence must occur (see 33 CFR 330.4(d)). The district
engineer or a State may require additional measures to ensure that the authorized activity is consistent with state
coastal zone management requirements.
27. Regional and Case-By-Case Conditions. The activity must comply with any regional conditions that
may have been added by the Division Engineer (see 33 CFR 330.4(e)) and with any case specific conditions
added by the Corps or by the state, Indian Tribe, or U.S. EPA in its section 401 Water Quality Certification, or
by the state in its Coastal Zone Management Act consistency determination.
28. Use of Multiple Nationwide Permits. The use of more than one NWP for a single and complete
project is prohibited, except when the acreage loss of waters of the United States authorized by the NWPs does
not exceed the acreage limit of the NWP with the highest specified acreage limit. For example, if a road
crossing over tidal waters is constructed under NWP 14, with associated bank stabilization authorized by NWP
13, the maximum acreage loss of waters of the United States for the total project cannot exceed 1/3 -acre.
29. Transfer of Nationwide Permit Verifications. If the permittee sells the property associated with a
nationwide permit verification, the permittee may transfer the nationwide permit verification to the new owner
by submitting a letter to the appropriate Corps district office to validate the transfer. A copy of the nationwide
permit verification must be attached to the letter, and the letter must contain the following statement and
signature:
“When the structures or work authorized by this nationwide permit are still in existence at the time the
property is transferred, the terms and conditions of this nationwide permit, including any special conditions, will
continue to be binding on the new owner(s) of the property. To validate the transfer of this nationwide permit
and the associated liabilities associated with compliance with its terms and conditions, have the transferee sign
and date below.”
_____________________________________________
(Transferee)

(Date)
30. Compliance Certification. Each permittee who receives an NWP verification letter from the Corps
must provide a signed certification documenting completion of the authorized activity and implementation of
any required compensatory mitigation. The success of any required permittee-responsible mitigation, including
the achievement of ecological performance standards, will be addressed separately by the district engineer. The
Corps will provide the permittee the certification document with the NWP verification letter. The certification
document will include:
(a) A statement that the authorized activity was done in accordance with the NWP authorization,
including any general, regional, or activity-specific conditions;
(b) A statement that the implementation of any required compensatory mitigation was completed in
accordance with the permit conditions. If credits from a mitigation bank or in-lieu fee program are used to
satisfy the compensatory mitigation requirements, the certification must include the documentation required by
33 CFR 332.3(l)(3) to confirm that the permittee secured the appropriate number and resource type of credits;
and
(c) The signature of the permittee certifying the completion of the activity and mitigation.
The completed certification document must be submitted to the district engineer within 30 days of
completion of the authorized activity or the implementation of any required compensatory mitigation,
whichever occurs later.
31. Activities Affecting Structures or Works Built by the United States. If an NWP activity also
requires permission from the Corps pursuant to 33 U.S.C. 408 because it will alter or temporarily or
permanently occupy or use a U.S. Army Corps of Engineers (USACE) federally authorized Civil Works project
(a “USACE project”), the prospective permittee must submit a pre-construction notification. See paragraph
(b)(10) of general condition 32. An activity that requires section 408 permission is not authorized by NWP
until the appropriate Corps office issues the section 408 permission to alter, occupy, or use the USACE project,
and the district engineer issues a written NWP verification.
32. Pre-Construction Notification. (a) Timing. Where required by the terms of the NWP, the prospective
permittee must notify the district engineer by submitting a pre-construction notification (PCN) as early as
possible. The district engineer must determine if the PCN is complete within 30 calendar days of the date of
receipt and, if the PCN is determined to be incomplete, notify the prospective permittee within that 30 day
period to request the additional information necessary to make the PCN complete. The request must specify the
information needed to make the PCN complete. As a general rule, district engineers will request additional
information necessary to make the PCN complete only once. However, if the prospective permittee does not
provide all of the requested information, then the district engineer will notify the prospective permittee that the
PCN is still incomplete and the PCN review process will not commence until all of the requested information
has been received by the district engineer. The prospective permittee shall not begin the activity until either:
(1) He or she is notified in writing by the district engineer that the activity may proceed under the NWP
with any special conditions imposed by the district or division engineer; or
(2) 45 calendar days have passed from the district engineer’s receipt of the complete PCN and the
prospective permittee has not received written notice from the district or division engineer. However, if the
permittee was required to notify the Corps pursuant to general condition 18 that listed species or critical habitat
might be affected or are in the vicinity of the activity, or to notify the Corps pursuant to general condition 20
that the activity might have the potential to cause effects to historic properties, the permittee cannot begin the
activity until receiving written notification from the Corps that there is “no effect” on listed species or “no
potential to cause effects” on historic properties, or that any consultation required under Section 7 of the
Endangered Species Act (see 33 CFR 330.4(f)) and/or section 106 of the National Historic Preservation Act
(see 33 CFR 330.4(g)) has been completed. Also, work cannot begin under NWPs 21, 49, or 50 until the
permittee has received written approval from the Corps. If the proposed activity requires a written waiver to
exceed specified limits of an NWP, the permittee may not begin the activity until the district engineer issues the
waiver. If the district or division engineer notifies the permittee in writing that an individual permit is required
within 45 calendar days of receipt of a complete PCN, the permittee cannot begin the activity until an individual
permit has been obtained. Subsequently, the permittee’s right to proceed under the NWP may be modified,
suspended, or revoked only in accordance with the procedure set forth in 33 CFR 330.5(d)(2).
(b) Contents of Pre-Construction Notification: The PCN must be in writing and include the following
information:
(1) Name, address and telephone numbers of the prospective permittee;
(2) Location of the proposed activity;
(3) Identify the specific NWP or NWP(s) the prospective permittee wants to use to authorize the
proposed activity;
(4) A description of the proposed activity; the activity’s purpose; direct and indirect adverse
environmental effects the activity would cause, including the anticipated amount of loss of wetlands, other
special aquatic sites, and other waters expected to result from the NWP activity, in acres, linear feet, or other
appropriate unit of measure; a description of any proposed mitigation measures intended to reduce the adverse
environmental effects caused by the proposed activity; and any other NWP(s), regional general permit(s), or
individual permit(s) used or intended to be used to authorize any part of the proposed project or any related
activity, including other separate and distant crossings for linear projects that require Department of the Army
authorization but do not require pre-construction notification. The description of the proposed activity and any
proposed mitigation measures should be sufficiently detailed to allow the district engineer to determine that the
adverse environmental effects of the activity will be no more than minimal and to determine the need for
compensatory mitigation or other mitigation measures. For single and complete linear projects, the PCN must
include the quantity of anticipated losses of wetlands, other special aquatic sites, and other waters for each
single and complete crossing of those wetlands, other special aquatic sites, and other waters. Sketches should be
provided when necessary to show that the activity complies with the terms of the NWP. (Sketches usually
clarify the activity and when provided results in a quicker decision. Sketches should contain sufficient detail to
provide an illustrative description of the proposed activity (e.g., a conceptual plan), but do not need to be
detailed engineering plans);
(5) The PCN must include a delineation of wetlands, other special aquatic sites, and other waters, such
as lakes and ponds, and perennial, intermittent, and ephemeral streams, on the project site. Wetland delineations
must be prepared in accordance with the current method required by the Corps. The permittee may ask the
Corps to delineate the special aquatic sites and other waters on the project site, but there may be a delay if the
Corps does the delineation, especially if the project site is large or contains many wetlands, other special aquatic
sites, and other waters. Furthermore, the 45 day period will not start until the delineation has been submitted to
or completed by the Corps, as appropriate;
(6) If the proposed activity will result in the loss of greater than 1/10-acre of wetlands and a PCN is
required, the prospective permittee must submit a statement describing how the mitigation requirement will be
satisfied, or explaining why the adverse environmental effects are no more than minimal and why compensatory
mitigation should not be required. As an alternative, the prospective permittee may submit a conceptual or
detailed mitigation plan.
(7) For non-Federal permittees, if any listed species or designated critical habitat might be affected or is
in the vicinity of the activity, or if the activity is located in designated critical habitat, the PCN must include the
name(s) of those endangered or threatened species that might be affected by the proposed activity or utilize the
designated critical habitat that might be affected by the proposed activity. For NWP activities that require pre-
construction notification, Federal permittees must provide documentation demonstrating compliance with the
Endangered Species Act;
(8) For non-Federal permittees, if the NWP activity might have the potential to cause effects to a historic
property listed on, determined to be eligible for listing on, or potentially eligible for listing on, the National
Register of Historic Places, the PCN must state which historic property might have the potential to be affected
by the proposed activity or include a vicinity map indicating the location of the historic property. For NWP
activities that require pre-construction notification, Federal permittees must provide documentation
demonstrating compliance with section 106 of the National Historic Preservation Act;
(9) For an activity that will occur in a component of the National Wild and Scenic River System, or in a
river officially designated by Congress as a “study river” for possible inclusion in the system while the river is
in an official study status, the PCN must identify the Wild and Scenic River or the “study river” (see general
condition 16); and
(10) For an activity that requires permission from the Corps pursuant to 33 U.S.C. 408 because it will
alter or temporarily or permanently occupy or use a U.S. Army Corps of Engineers federally authorized civil
works project, the pre-construction notification must include a statement confirming that the project proponent
has submitted a written request for section 408 permission from the Corps office having jurisdiction over that
USACE project.
(c) Form of Pre-Construction Notification: The standard individual permit application form (Form ENG
4345) may be used, but the completed application form must clearly indicate that it is an NWP PCN and must
include all of the applicable information required in paragraphs (b)(1) through (10) of this general condition. A
letter containing the required information may also be used. Applicants may provide electronic files of PCNs
and supporting materials if the district engineer has established tools and procedures for electronic submittals.
(d) Agency Coordination: (1) The district engineer will consider any comments from Federal and state
agencies concerning the proposed activity’s compliance with the terms and conditions of the NWPs and the
need for mitigation to reduce the activity’s adverse environmental effects so that they are no more than minimal.
(2) Agency coordination is required for: (i) all NWP activities that require pre-construction notification
and result in the loss of greater than 1/2-acre of waters of the United States; (ii) NWP 21, 29, 39, 40, 42, 43, 44,
50, 51, and 52 activities that require pre-construction notification and will result in the loss of greater than 300
linear feet of stream bed; (iii) NWP 13 activities in excess of 500 linear feet, fills greater than one cubic yard
per running foot, or involve discharges of dredged or fill material into special aquatic sites; and (iv) NWP 54
activities in excess of 500 linear feet, or that extend into the waterbody more than 30 feet from the mean low
water line in tidal waters or the ordinary high water mark in the Great Lakes.
(3) When agency coordination is required, the district engineer will immediately provide (e.g., via e-
mail, facsimile transmission, overnight mail, or other expeditious manner) a copy of the complete PCN to the
appropriate Federal or state offices (FWS, state natural resource or water quality agency, EPA, and, if
appropriate, the NMFS). With the exception of NWP 37, these agencies will have 10 calendar days from the
date the material is transmitted to notify the district engineer via telephone, facsimile transmission, or e-mail
that they intend to provide substantive, site-specific comments. The comments must explain why the agency
believes the adverse environmental effects will be more than minimal. If so contacted by an agency, the district
engineer will wait an additional 15 calendar days before making a decision on the pre-construction notification.
The district engineer will fully consider agency comments received within the specified time frame concerning
the proposed activity’s compliance with the terms and conditions of the NWPs, including the need for
mitigation to ensure the net adverse environmental effects of the proposed activity are no more than minimal.
The district engineer will provide no response to the resource agency, except as provided below. The district
engineer will indicate in the administrative record associated with each pre-construction notification that the
resource agencies’ concerns were considered. For NWP 37, the emergency watershed protection and
rehabilitation activity may proceed immediately in cases where there is an unacceptable hazard to life or a
significant loss of property or economic hardship will occur. The district engineer will consider any comments
received to decide whether the NWP 37 authorization should be modified, suspended, or revoked in accordance
with the procedures at 33 CFR 330.5.
(4) In cases of where the prospective permittee is not a Federal agency, the district engineer will provide
a response to NMFS within 30 calendar days of receipt of any Essential Fish Habitat conservation
recommendations, as required by section 305(b)(4)(B) of the Magnuson-Stevens Fishery Conservation and
Management Act.
(5) Applicants are encouraged to provide the Corps with either electronic files or multiple copies of pre-
construction notifications to expedite agency coordination.
3. Regional Conditions for the Los Angeles District:
1. For all activities in waters of the U.S. that are suitable habitat for federally listed fish species, including
designated critical habitat for such species, the permittee shall design all new or substantially reconstructed
linear transportation crossings (e.g. roads, highways, railways, trails, bridges, culverts) to ensure that the
passage and/or spawning of fish is not hindered. In these areas, the permittee shall employ bridge designs
that span the stream or river, including pier- or pile-supported spans, or designs that use a bottomless arch
culvert with a natural stream bed, unless determined to be impracticable by the Corps.
2. Nationwide Permits (NWP) 3, 7, 12-15, 17-19, 21, 23, 25, 29, 35, 36, or 39-46, 48-54 cannot be used to
authorize structures, work, and/or the discharge of dredged or fill material that would result in the "loss" of
wetlands, mudflats, vegetated shallows or riffle and pool complexes as defined at 40 CFR Part 230.40-45.
The definition of "loss" for this regional condition is the same as the definition of "loss of waters of the
United States" used for the Nationwide Permit Program. Furthermore, this regional condition applies only
within the State of Arizona and within the Mojave and Sonoran (Colorado) desert regions of California.
The desert regions in California are limited to four USGS Hydrologic Unit Code (HUC) accounting units
(Lower Colorado -150301, Northern Mojave-180902, Southern Mojave-181001, and Salton Sea-181002).
3. When a pre-construction notification (PCN) is required, the Los Angeles District shall be notified in
accordance with General Condition 32 using either the South Pacific Division PCN Checklist or a signed
application form (ENG Form 4345) with an attachment providing information on compliance with all of the
General and Regional Conditions. The PCN Checklist and application form are available at:
http://www.spl.usace.army.mil/Missions/Regulatory/PermitProcess.aspx. In addition, unless specifically
waived by the Los Angeles District, the PCN shall include:
a. A written statement describing how the activity has been designed to avoid and minimize adverse
effects, both temporary and permanent, to waters of the United States;
b. Drawings, including plan and cross-section views, clearly depicting the location, size and
dimensions of the proposed activity as well as the location of delineated waters of the U.S. on the
site. The drawings shall contain a title block, legend and scale, amount (in cubic yards) and area (in
acres) of fill in Corps jurisdiction, including both permanent and temporary fills/structures. The
ordinary high water mark or, if tidal waters, the mean high water mark and high tide line, should be
shown (in feet), based on National Geodetic Vertical Datum (NGVD) or other appropriate
referenced elevation. All drawings shall follow the Updated Map and Drawing Standards for the
South Pacific Division Regulatory Program (Feb 2016), or most recent update (available at the South
Pacific Division website at:
http://www.spd.usace.army.mil/Missions/Regulatory/PublicNoticesandReferences.aspx/ );
c. Numbered and dated pre-project color photographs showing a representative sample of waters
proposed to be impacted on the project site, and all waters proposed to be avoided on and
immediately adjacent to the project site. The compass angle and position of each photograph shall be
documented on the plan-view drawing required in subpart b of this regional condition.
d. Delineation of aquatic resources in accordance with the current Los Angeles District’s Minimum
Standards for Acceptance of Aquatic Resources Delineation Reports (available at:
http://www.spl.usace.army.mil/Missions/Regulatory/Jurisdictional-Determination/).
4. Submission of a PCN pursuant to General Condition 32 and Regional Condition 3 shall be required for
specific regulated activities in the following locations:
a. All perennial waterbodies and special aquatic sites throughout the Los Angeles District as well as
intermittent waters within the State of Arizona for any regulated activity that would result in a loss
of waters of the United States. The definition of “loss of waters of the United States” for this
regional condition is the same as the definition used for the Nationwide Permit Program.
b. All areas designated as Essential Fish Habitat (EFH) by the Pacific Fishery Management Council,
and that would result in an adverse effect to EFH, in which case the PCN shall include an EFH
assessment and extent of proposed impacts to EFH. EFH Assessment Guidance and other supporting
information can be found at:
http://www.westcoast.fisheries.noaa.gov/habitat/fish_habitat/efh_consultations_go.html.
c. All watersheds in the Santa Monica Mountains in Los Angeles and Ventura counties bounded by
Calleguas Creek on the west, by Highway 101 on the north and east, and by Sunset Boulevard and
Pacific Ocean on the south.
d. The Santa Clara River watershed in Los Angeles and Ventura counties, including but not limited to
Aliso Canyon, Agua Dulce Canyon, Sand Canyon, Bouquet Canyon, Mint Canyon, South Fork of
the Santa Clara River, San Francisquito Canyon, Castaic Creek, Piru Creek, Sespe Creek and the
main-stem of the Santa Clara River.
e. The Murrieta and Temecula Creek watersheds in Riverside County, California for any regulated
activity that would result in a loss of waters of the U.S. The definition of “loss of waters of the
United States” for this regional condition is the same as the definition used for the Nationwide
Permit Program.
f. All waterbodies designated by the Arizona Department of Environmental Quality as Outstanding
Arizona Waters (OAWs), within 1600 meters (or 1 mile) upstream and/or 800 meters (1/2 mile)
downstream of a designated OAW, and on tributaries to OAWs within 1600 meters of the OAW (see
http://www.azdeq.gov/index.html).
g. All waterbodies designated by the Arizona Department of Environmental Quality as 303(d)-impaired
surface waters, within 1600 meters (or 1 mile) upstream and/or 800 meters (1/2 mile) downstream of
a designated impaired surface water, and on tributaries to impaired waters within 1600 meters of the
impaired water (see http://www.azdeq.gov/index.html).
5. Individual Permits shall be required for all discharges of fill material in jurisdictional vernal pools, with the
exception that discharges for the purpose of restoration, enhancement, management or scientific study of
vernal pools may be authorized under NWPs 5, 6, and 27 with the submission of a PCN in accordance with
General Condition 32 and Regional Condition 3.
6. Within the Murrieta Creek and Temecula Creek watersheds in Riverside County the use of NWPs 29, 39, 42
and 43, and NWP 14 combined with any of those NWPs shall be restricted. The loss of waters of the U.S.
cannot exceed 0.25 acre. The definition of “loss of waters of the United States” for this regional condition is
the same as the definition used for the Nationwide Permit Program.
7. Individual Permits (Standard Individual Permit or 404 Letter of Permission) shall be required in San Luis
Obispo Creek and Santa Rosa Creek in San Luis Obispo County for bank stabilization projects, and in
Gaviota Creek, Mission Creek and Carpinteria Creek in Santa Barbara County for bank stabilization
projects and grade control structures.
8. In conjunction with the Los Angeles District's Special Area Management Plans (SAMPs) for the San Diego
Creek Watershed and San Juan Creek/Western San Mateo Creek Watersheds in Orange County, California,
the Corps' Division Engineer, through his discretionary authority has revoked the use of the following 26
selected NWPs within these SAMP watersheds: 03, 07, 12, 13, 14, 16, 17, 18, 19, 21, 25, 27, 29, 31, 33, 39,
40, 41, 42, 43, 44, 46, 49, and 50. Consequently, these NWPs are no longer available in those watersheds to
authorize impacts to waters of the United States from discharges of dredged or fill material under the Corps'
Clean Water Act section 404 authority.
9. Any requests to waive the applicable linear foot limitations for NWPs 13, 21, 29, 39, 40 and 42, 43, 44, 51,
52, and 54, must include the following:
a. A narrative description of the affected aquatic resource. This should include known information on:
volume and duration of flow; the approximate length, width, and depth of the waterbody and
characters observed associated with an Ordinary High Water Mark (e.g. bed and bank, wrack line, or
scour marks) or Mean High Water Line; a description of the adjacent vegetation community and a
statement regarding the wetland status of the associated vegetation community (i.e. wetland, non-
wetland); surrounding land use; water quality; issues related to cumulative impacts in the watershed,
and; any other relevant information.
b. An analysis of the proposed impacts to the waterbody in accordance with General Condition 32 and
Regional Condition 3;
c. Measures taken to avoid and minimize losses, including other methods of constructing the proposed
project; and
d. A compensatory mitigation plan describing how the unavoidable losses are proposed to be
compensated, in accordance with 33 CFR Part 332.
10. The permittee shall complete the construction of any compensatory mitigation required by special
condition(s) of the NWP verification before or concurrent with commencement of construction of the
authorized activity, except when specifically determined to be impracticable by the Corps. When mitigation
involves use of a mitigation bank or in-lieu fee program, the permittee shall submit proof of payment to the
Corps prior to commencement of construction of the authorized activity.
