On December 18, 2013, the Jacksonville District of the U.S. Army Corps of Engineers (Corps) provided public notice of the setback criterion to be utilized for the review of structures proposed to be placed along certain Federal channels (Setback Guidance). The Setback Guidance applies to works and structures located within the following waterways:
• Atlantic Intracoastal Waterway (AIWW) from the Florida State line south to the St. Johns River,
• Intracoastal Waterway (IWW) on the east coast of Florida from the St. Johns River to Miami,
• Intracoastal Waterway (GIWW) on the west coast of Florida from the Caloosahatchee River to the Anclote River,
• Okeechobee Waterway (OWW) those portions not covered by Regional General Permit number 67. This would include the waterway from the W.P. Franklin Lock and Control Structure west to Punta Rassa and from the St. Lucie Lock and Dam east to its intersection with the east coast Intracoastal Waterway.
Establishing Setback Guidance is necessary to advise the public of the manner in which Jacksonville District intends to exercise its authority under the R&HA to (1) maintain the navigable capacity of the Federal channels by minimizing both potential hazards to navigation and impediments to maintenance dredging created by structures located along the edges of the channels and (2) ensure that proposed modifications do not impair the usefulness of a Federal project and are not injurious to the public interest. For these reasons, the setback for all structures is 100’ from the near design edge of the aforementioned federal channel. The December 2013 Setback Guidance superseded all previous setback policy, criteria, and/or guidance established by the Jacksonville District.
Under the December 2013 Setback Guidance, applicants requesting a variance to the 100-foot setback to place a structure closer than 62.5’ from the near design edge of the federal channel, were required (to the maximum extent practicable) to restrict the width of the structure to 1/3 of the lot’s shoreline, up to a maximum width of 40'. The 1/3 width, up to 40' maximum criteria in the 2013 Guidance was intended to reduce the potential of structures to impact the navigable capacity of the Federal channels by minimizing both potential hazards to navigation and impediments to maintenance dredging created by structures located along the edges of the channels. The Corps has decided to remove the maximum 40' restriction associated with variances to the setback, but retain the restriction that the width of the structure not exceed 1/3 of the width of the shoreline when centered on the property.
The Setback Guidance does not have binding effect. It is guidance to the public which provides predictability on how the Corps reviews structures along certain federal channels. Each proposed project is reviewed on case-by-case based on site specific information and there is no guarantee that proposed structures will be authorized closer than 100' from the near design edge, consistent with the waterward extent of neighboring structures, or up to 1/3 the width of the shoreline. Removal of the 40' width restriction recognizes the Corps’ flexibility to allow, as appropriate under its authorities, variances to the 100' setback for development up to 1/3 of the shoreline for properties which exceed 120' of shoreline. This revision will not diminish the Corps’ ability to operate and maintain the Federal channels in an efficient, cost-effective and environmentally acceptable manner.
The revised Setback Guidance is effective concurrent with this public notice and is available on our website at http://www.saj.usace.army.mil/Missions/Regulatory/ItemsofInterest.aspx.

PUBLIC NOTICE
U.S. Army Corps of Engineers, Jacksonville District,
Setback Guidance for Structures along Certain Federal Channels
On December 18, 2013, the Jacksonville District of the U.S. Army Corps of Engineers
(Corps) provided public notice of the setback criterion to be utilized for the review of
structures proposed to be placed along certain Federal channels (Setback Guidance).
The Setback Guidance applies to works and structures located within the following
waterways:
· Atlantic lntracoastal Waterway (AIWW) from the Florida State line south to the
St. Johns River,
· lntracoastal Waterway (IWW) on the east coast of Florida from the St. Johns
River to Miami,
· lntracoastal Waterway (GIWW) on the west coast of Florida from the
Caloosahatchee River to the Anclote River,
· Okeechobee Waterway (OWW) those portions not covered by Regional
General Permit number 67. This would include the waterway from the W.P.
Franklin Lock and Control Structure west to Punta Rassa and from the St.
Lucie Lock and Dam east to its intersection with the east coast lntracoastal
Waterway.
Establishing Setback Guidance is necessary to advise the public of the manner in which
Jacksonville District intends to exercise its authority under the R&HA to (1) maintain the
navigable capacity of the Federal channels by minimizing both potential hazards to
navigation and impediments to maintenance dredging created by structures located along
the edges of the channels and (2) ensure that proposed modifications do not impair the
usefulness of a Federal project and are not injurious to the public interest. For these
reasons, the setback for all structures is 100' from the near design edge of the
aforementioned federal channel. The December 2013 Setback Guidance superseded all
previous setback policy, criteria, and/or guidance established by the Jacksonville District.
Under the December 2013 Setback Guidance, applicants requesting a variance to the
100-foot setback to place a structure closer than 62.5' from the near design edge of the
federal channel, were required (to the maximum extent practicable) to restrict the width of
the structure to 1/3 of the lot's shoreline, up to a maximum width of 40'. The 1/3 width, up
to 40' maximum criteria in the 2013 Guidance was intended to reduce the potential of
structures to impact the navigable capacity of the Federal channels by minimizing both
potential hazards to navigation and impediments to maintenance dredging created by
-2-
structures located along the edges of the channels. The Corps has decided to remove the
maximum 40' restriction associated with variances to the setback, but retain the restriction
that the width of the structure not exceed 1/3 of the width of the shoreline when centered
on the property. This revision is reflected in the updated Setback Guidance dated
November 9, 2017.
The Setback Guidance does not have binding effect. It is guidance to the public which
provides predictability on how the Corps reviews structures along certain federal channels.
Each proposed project is reviewed on case-by-case based on site specific information and
there is no guarantee that proposed structures will be authorized closer than 100' from the
near design edge, consistent with the waterward extent of neighboring structures, or up to
1/3 the width of the shoreline. Removal of the 40' width restriction recognizes the Corps'
flexibility to allow, as appropriate under its authorities, variances to the 100' setback for
development up to 1/3 of the shoreline for properties which exceed 120' of shoreline. This
revision will not diminish the Corps' ability to operate and maintain the Federal channels in
an efficient, cost-effective and environmentally acceptable manner.
The revised Setback Guidance is effective concurrent with this public notice and is

MEMORANDUM FOR RECORD
SUBJECT: U.S. Army Corps of Engineers, Jacksonville District, Setback Guidance for
Structures along Certain Federal Channels
1. PURPOSE: This memorandum updates the U.S. Army Corps of Engineers, Jacksonville
District, (Corps) guidance regarding setback policy (Guidance) for structures along the Federal
channels, established by memorandum dated 18 December 2013. The Guidance is revised herein
to remove the maximum 40 foot width of a structure parallel to the shoreline when closer than
62.5 feet from the near design edge and instead allow structures up to 1/3 the width of the
shoreline. In accordance with Section 10 of the Rivers and Harbors Act of 1899 (R&HA Section
10), the Corps has the authority to regulate any obstruction to the navigable capacity of waters of
the United States not affirmatively authorized by Congress. Furthermore, in accordance with
Section 14 of the Rivers and Harbors Act of 1899 (33 USC § 408) (Section 408), the Corps has
the authority to review requests for modifications to Federal projects by non-Federal interests.
The purpose of the Guidance is to advise the public and Jacksonville District personnel of the
manner in which Jacksonville District intends to exercise its authority under the R&HA to (1)
maintain the navigable capacity of the Federal channels by minimizing both potential hazards to
navigation and impediments to maintenance dredging created by structures located along the
edges of the channels and (2) ensure that proposed modifications do not impair the usefulness of
a Federal project and are not injurious to the public interest. It is the Corps' intent to equitably
manage the construction of structures along the Federal channels so that, to the extent
practicable, property owners achieve some form of structural access while ensuring the
Government's ability to maintain such waterways and the public's rights to safe navigation.
2. DEFINITIONS: The following terms are defined for the purpose of this memorandum. See
Appendices for diagrams depicting some of the following terms.
a. channel Those areas within the waterways listed in Paragraph 3 of this Guidance that
are part of a Congressionally authorized federal navigation project. This refers to the area
located between the design edges.
b. currently serviceable A structure is considered to be currently serviceable if it is usable
as is but not so degraded or damaged as to essentially require reconstruction.
c. design depth The depth to which the Corps has been authorized to maintain the Federal
channel by the enabling legislation for that Federal project. This defines the depth parameter
of the area between the design edges of the Federal channel with respect to mean lower low
water elevations.
d. design edge The surveyed edges of a Federal channel which the Corps has been
authorized to maintain by the enabling legislation for that Federal project. The distance
between the design edges defines the width of the Federal channel.
CESAJ (1200A)
SUBJECT: U.S. Army Corps of Engineers, Jacksonville District, Setback Guidance for
Structures along Certain Federal Channels
e. hydrographic survey A survey designed to present an accurate, measurable description
of the submerged terrain. The survey must show a plan view of the entire project area,
including all areas where structures and mooring will be located, arranged in such a manner
as to show lines of equal depth with respect to mean lower low water elevation. See
Appendix A for more information on this requirement.
f. mean lower low water (MLLW) The average of the lower low water height of each tidal
day observed over the National Tidal Datum Epoch (NTDE). The NTDE is actively
considered for revision every 20 to 25 years and the present NTDE is 1983 through 2001.
g. most waterward This is considered to be that portion of a structure which lies closest to
the near design edge of the federally authorized navigational channel. For purposes of
measuring the setback of a structure, this point could be, but is not limited to, mooring
pilings, decking, boat hoist/lifts or the roof line.
h. near design edge - The design edge of the federally authorized navigational channel that
is closest to the work/site.
i. riprap For this document, riprap is considered to be a type of revetment. Revetments are
generally sloping structures placed along a shoreline in such a way as to absorb the energy
of incoming waves. A riprap revetment is generally constructed of concrete or stone rubble
of varying sizes.
j. setback The area between the near design edge of a federal channel extending
horizontally 100 feet landward.
k. side slope The inclined area located adjacent to and outside of the established design
edges of the Federal channel going from the design depth at the near design edge to the top
edge of slope.
l. structures Any pier, boat dock, boat ramp, wharf, dolphin, weir, boom, breakwater,
bulkhead, revetment, riprap, jetty, artificial island, artificial reef, permanent mooring
structure, power transmission line, permanently moored floating vessel, piling, aid to
navigation, or any other obstacle or obstruction.
m. submerged bulkhead Any structure constructed such that it extends into the bottom
contour (natural or dredged) of the waterbody and is partially or completely submerged at
mean low water, which is designed to stop/reduce shoaling within the boat mooring area.
Submerged bulkheads are not considered to be essential to support the integrity of the
associated dock structure.
2
CESAJ (1200A)
SUBJECT: U.S. Army Corps of Engineers, Jacksonville District, Setback Guidance for
Structures along Certain Federal Channels
n. top edge of slope The reference point determined by multiplying the design depth of the
channel by the channel slope; a slope ratio of 3:1 will be utilized for this guidance. The
resulting value gives the horizontal distance from the design edge to the top edge of slope.
For example, when the design depth of a channel is 10 feet, then design edge will be 30 feet
from the top edge of slope.
o. terminal platform - A terminal platform is that part of a structure located at or near the
waterward terminus of the structure which is designed to secure and load or unload a vessel
or conduct other water dependent activities but which may also be used for other non-water
dependent activities.
p. wave break - Wave breaks are defined as boards, sheet piling or any materials that are
constructed as part of docks, boat and anchoring locations, walkways, and fishing piers that
are not necessary for the integrity of the structure. The purpose of these structures is to
stop/reduce shoaling within the boat mooring area and minimize wave damage.
q. X&Y State Plane Coordinates (X&Ys) - A set of two coordinates which describe a
unique point based on the State Plane Coordinate System. The X&Ys are utilized to identify
the location of the most waterward corners of a structure, proposed or existing. These
coordinate points are used by the Corps to determine the horizontal distance between the
most waterward portion of the structure and the near design edge of the Federal channel.
See Paragraph 4.b. (page 4) and Appendix A for more information X&Ys as they pertain to
this Guidance.
3. APPLICABILITY:
a. This Guidance supersedes all previous setback guidance and memoranda for structures
issued by the Corps' Jacksonville District and will be applicable to all structures located within
the setback along the following Federal navigation project waterways:
Atlantic Intracoastal Waterway from the Florida State line south to the St. Johns River,
Intracoastal Waterway on the east coast of Florida, from the St. Johns River south to
Miami,
Intracoastal Waterway on the west coast of Florida, from the Caloosahatchee River north
to the Anclote River,
Okeechobee Waterway, those portions not covered by Regional General Permit number 67.
This would include the waterway from the W.P. Franklin Lock and Control Structure west to
Punta Rassa and from the St. Lucie Lock and Dam east to its intersection with the east coast
Intracoastal Waterway.

CESAJ (1200A)
SUBJECT: U.S. Army Corps of Engineers, Jacksonville District, Setback Guidance for
Structures along Certain Federal Channels
b. This Guidance may be modified as necessary to ensure the navigable capacity of the
above-listed waterways.
c. This Guidance does not create any rights or obligations.
d. Nothing in this Guidance shall limit the ability of the Corps to issue, modify, suspend,
revoke, or deny any individual permit or general permit nor shall this Guidance limit the
Corps' ability to exercise its enforcement authority under the Rivers and Harbors Act of
1899.
4. GENERAL INFORMATION:
a. All applications seeking authorization for the construction of structures at or within the
setback of a Federal channel will indicate the mooring locations of vessels expected to use the
structure. If mooring to the waterward side of the terminus of the structure is proposed and no
mooring pilings are included in the application, a minimum vessel beam width of 10 feet will be
applied to establish the setback distance of the structure. A larger beam width may be utilized if
information is provided or obtained which indicates larger vessels will be docked at the structure.
b. All applications seeking authorization for the construction of structures to be located at or
within the setback of a Federal channel will be required to supply X&Ys for the most waterward
points of the structure. Additionally, all authorized projects will be required to submit an as-built
survey with X&Ys upon completion of the work for review and verification by the Corps'
Regulatory Division. See Appendix A for further information regarding the requirements
associated with the submittal of X&Ys.
c. All applications seeking authorization for the construction of docking and mooring
structures to be located at or within the setback (as defined in Paragraph 5 below) of a Federal
channel will be required to supply a hydrographic survey of the location of the structure. See
Appendix A for further information regarding the requirements associated with a hydrographic
survey. Generally, vertical bulkheads, information signs, and aids to navigation will not require a
hydrographic survey; however, on a case-by-case basis the Corps may require a hydrographic
survey for other structures to be located at or within the setback.
d. Provided structures along those Federal channels identified in Paragraph 3 above comply
with this Guidance, no project-specific permit under Section 408 will likely be required.
5. SETBACK GUIDANCE: The setback for all structures constructed along the channel of the
Federal navigation project waterways identified in Paragraph 3 of this guidance is 100 feet from
the near design edge of the channel. All permit applications seeking authorization for the
4
CESAJ (1200A)
SUBJECT: U.S. Army Corps of Engineers, Jacksonville District, Setback Guidance for
Structures along Certain Federal Channels
construction of structures within 100 feet of the near design edge of the Federal channel will be
reviewed by the Corps and are subject to review by the non-Federal, local sponsor of the affected
portion of the Federal channel. During the review and evaluation of all applications seeking
authorization for the construction of structures within the setback, every effort will be made to
locate any structure authorized as far from the near design edge of the channel as practicable.
6. VARIANCES TO SETBACK:
a. All applicants requesting a variance to the 100-foot setback must provide justification for
allowance of a potential impact to both the navigable capacity of the channel and the Federal
Government's ability to maintain the channel. The information supplied to provide justification
may include, but is not limited to, the horizontal distance between the shoreline and the edge of
the federal channel, the actual water depth at MLLW, the presence of submerged vegetation or
shoreline vegetation (i.e. sea grasses or mangrove fringe), public health and safety issues, and the
proposed use of the structure. All of the information supplied to justify authorization of the
structure will be used during the review and evaluation of the work proposal. See Appendix B
for more information on these design restrictions.
b. If the applicant is seeking authorization to place a structure such that any portion of it will
be located within 62.5 feet of the near design edge of the channel and the justification provided is
inadequate water depth, the applicant must show that dredging an access channel to allow
placement of the structure more than 62.5 feet from the near design edge of the channel has been
denied by a local, state or federal agency with the authority to regulate the dredging activity.
c. In no case will any structure be allowed to be constructed such that any portion of it, or any
vessel utilizing it, is located closer to the near design edge of the Federal channel than the top
edge of the slope plus 2 feet. For example, if the top edge of slope is located 30 feet from the
near design edge of the federal channel, no structure will be authorized such that any portion of
that structure is located closer than 32 feet (30 feet + 2 feet) from the near design edge of the
channel. The following table provides information on the design depth and minimum clearance
requirements for each of the Federal Channels listed in Paragraph 3.a.

7. RESTRICTIONS ASSOCIATED WITH VARIANCES TO SETBACK:
Applications for structures which are seeking authorization to be located closer than 62.5 feet
from the near design edge of the Federal channel will be required, to the maximum extent
practicable, to adhere to the design guidance provided below to reduce their potential impact to
both the navigable capacity of the channel and the Federal Government's ability to maintain the
channel. Site specific information will be reviewed when determining if there is a need to
deviate from the design guidance provided below. See Appendix C for more information on
these design restrictions.
a. The width of the structure may not exceed 1/3 of the width of the waterward edge of the lot.
The width of the structure will be determined by including any hoist, lift, mooring piling, roof
overhang or any other structure used in conjunction with the mooring structure. Additionally,
the terminal platform portion of the structure must be centered on the waterward edge of the lot.
The access pier may be located at any point along the landward side of the terminal platform.
6
CESAJ (1200A)
SUBJECT: U.S. Army Corps of Engineers, Jacksonville District, Setback Guidance for
Structures along Certain Federal Channels
b. Where local restrictions require that two adjacent lots share an access pier, the width
restriction noted in Paragraph 7.a. will apply to each half of the structure. The access pier must
be centered on the shared property line.
c. A submerged bulkhead or wave break may not be allowed to be constructed such that any
portion of the structure is located closer than 62.5 feet from the near design edge of the channel.
d. Riprap may not be allowed as a shoreline stabilization method when it is to be located
closer than 62.5 feet from the near design edge of the channel.
8. Existing Structures: Generally, previously authorized, currently serviceable structures may be
repaired or rehabilitated, in accordance with their Department of the Army authorization, such
that they maintain the authorized footprint and do not extend beyond their authorized distance
from the near design edge of the Federal channel provided that the structure is not to be put to
uses differing from those uses specified or contemplated for in the original permit or the most
recently authorized modification. A pre-construction notification is required and the Corps will
make the determination of whether an existing structure is currently serviceable. Any
modification, including minor deviations, will be reviewed pursuant to the setback guidance in
effect at the time of the request.
In the event that a previously authorized, currently serviceable structure is destroyed by an act of
nature or other event, a new application will be required which will be reviewed pursuant to the
setback guidance in effect at the time of the request. It is possible that any authorized
reconstruction will not be the same size or design as the original structure.
