John H. Chafee Coastal Barrier Resources System; Availability of 
Final Revised Maps for Michigan, Minnesota, Mississippi, Ohio, South 
Carolina, Texas, and Wisconsin

AGENCY: Fish and Wildlife Service, Interior.

ACTION: Notice of availability.

-----------------------------------------------------------------------

SUMMARY: The Coastal Barrier Resources Act requires the Secretary of 
the Interior to review the maps of the John H. Chafee Coastal Barrier 
Resources System (CBRS) at least once every 5 years and make any minor 
and technical modifications to the boundaries of the CBRS as are 
necessary to reflect changes that have occurred in the size or location 
of any unit as a result of natural forces. We, the U.S. Fish and 
Wildlife Service, have conducted this review for all of the CBRS units 
in Michigan, Minnesota, Mississippi, North Carolina, Ohio, Texas, and 
Wisconsin, and 10 units in South Carolina. This notice announces the 
findings of our review and the availability of final revised maps for 
116 CBRS units in the project area, except for the North Carolina 
units. We did not prepare final revised maps for the North Carolina 
units because sufficient data was not available in some areas.

DATES: Changes to the CBRS depicted on the final revised maps, dated 
December 30, 2022, become effective on August 16, 2023.

ADDRESSES: For information about how to get copies of the maps or where 
to go to view them, see the Availability of Final Maps and Related 
Information section.

SUPPLEMENTARY INFORMATION: 

Background and Methodology

    Background information on the Coastal Barrier Resources Act (CBRA; 
16 U.S.C. 3501 et seq.) and the John H. Chafee Coastal Barrier 
Resources System (CBRS), as well as information on the 5-year review 
effort and the methodology used to produce the revised maps, can be 
found in a notice the U.S. Fish and Wildlife Service (Service) 
published in the Federal Register on November 22, 2022 (87 FR 71352).

Announced Map Modifications

    This notice announces modifications to the maps for several CBRS 
units in Michigan, Minnesota, Mississippi, Ohio, South Carolina, Texas, 
and Wisconsin. Most of the modifications were made to reflect changes 
to the CBRS units as a result of natural forces (e.g., erosion and 
accretion). CBRA requires the Secretary of the Interior (Secretary) to 
review the maps of the CBRS at least once every 5 years and make, in 
consultation with the appropriate Federal, State, and local officials, 
such minor and technical modifications to the boundaries of the CBRS as 
are necessary solely to reflect changes that have occurred in the size 
or location of any unit as a result of natural forces (16 U.S.C. 
3503(c)).
    The Service's review resulted in a set of 118 final revised maps, 
dated December 30, 2022, depicting a total of 116 CBRS units. The set 
of maps includes:

 36 maps for 46 CBRS units located in Michigan
 1 map for 1 CBRS unit located in Minnesota
 9 maps for 7 CBRS units located in Mississippi
 7 maps for 10 CBRS units located in Ohio
 7 maps for 10 CBRS units located in South Carolina
 53 maps for 35 CBRS units located in Texas
 5 maps for 7 CBRS units located in Wisconsin

    The Service made modifications to a total of 18 CBRS units (of the 
133 units reviewed) due to natural changes in their size or location 
since they were last mapped. No revised maps were prepared for the 17 
North Carolina units that were included in our initial review. Because 
of ongoing geomorphic change in certain units and the need for 
additional data, the North Carolina units will be reviewed again in the 
future.

[[Page 55711]]

Consultation With Federal, State, and Local Officials

    CBRA requires consultation with the appropriate Federal, State, and 
local officials (stakeholders) on the proposed CBRS boundary 
modifications to reflect changes that have occurred in the size or 
location of any CBRS unit as a result of natural forces (16 U.S.C 
3503(c)). The Service fulfilled this requirement by holding a 30-day 
comment period on the draft revised boundaries for Federal, State, and 
local stakeholders, from November 22, 2022, through December 22, 2022. 
This comment period was announced in a notice published in the Federal 
Register (87 FR 71352) on November 22, 2022.
    The Service notified approximately 340 stakeholders concerning the 
availability of the draft revised boundaries, including: (1) the Chair 
and Ranking Member of the House of Representatives Committee on Natural 
Resources, the Chair and Ranking Member of the Senate Committee on 
Environment and Public Works, and the members of the Senate and House 
of Representatives for the affected areas; (2) the governors of the 
affected areas; (3) State and local officials with floodplain 
management and/or land use responsibilities; and (4) Federal officials 
with knowledge of the coastal geomorphology within the project area.

Comments and Service Responses

    Below is a summary of the 10 written comments and/or 
acknowledgements received from stakeholders (Federal, State, and local 
officials) and the Service's responses. One additional anonymous 
comment not pertaining to the 5-year review was received but is not 
summarized below. Interested parties may view the comments received 
during the stakeholder review period at https://www.regulations.gov 
under Docket No. FWS-HQ-ES-2022-0107 or may contact the Service 
individual identified in the FOR FURTHER INFORMATION CONTACT section to 
make arrangements to view copies of the comments.
    (1.) Comment from the Manistee County Planning Department, 
Michigan: Manistee County indicated that the proposed change in the 
CBRS boundary around Snake Island appeared to be accurate. However, 
they raised a concern with the inland shoreline of Arcadia Lake, which 
they assert is not accurately shown on the point (located on the north 
side of the lake) and asked that it be corrected.
    Our Response: We reviewed the official November 2, 1994, map for 
Unit MI-21, which is based upon a 1983 U.S. Geological Survey 
topographic quadrangle, and found that the boundary in question was not 
drawn to follow the shoreline of Arcadia Lake. Because this particular 
segment of boundary was not drawn to follow a geomorphic feature on the 
official map, no changes are warranted through the 5-year review 
process.
    (2.) Comment from Representative Gregory F. Murphy, MD, House of 
Representatives, 3rd District, North Carolina: Representative Murphy 
requested that the Service exclude the lots serviced by infrastructure 
along North Carolina Highway 210 and New River Inlet Road from Unit 
L06, because he asserts these lots were mistakenly placed in the unit 
when the CBRS was first mapped.
    Our Response: Changes to the CBRS boundaries through the 5-year 
review effort are limited to the administrative modifications the 
Secretary is authorized to make under CBRA (16 U.S.C. 3503(c)-(e)). 
Changes that are outside the scope of this authority must be made 
through the comprehensive map modernization process, which entails 
Congressional enactment of legislation to make the revised maps 
effective. Unit L06 has already undergone the comprehensive map 
modernization process, and the revised maps for the unit were adopted 
by Congress via the Strengthening Coastal Communities Act of 2018 (Pub. 
L. 115-358). These maps (dated December 21, 2018) removed about 78 
structures from the CBRS and added about 170 acres to the CBRS (mostly 
wetlands). The results of the Service's review of the level of 
infrastructure within Unit L06 are described in our response to Comment 
15 in Appendix E of our 2016 Final Report to Congress: John H. Chafee 
Coastal Barrier Resources System Digital Mapping Pilot Project. While 
we found some structures on the ground and a main trunk line of 
infrastructure that ran along the length of the unit in 1982 when it 
was first included within the CBRS, the area still met the CBRA 
criteria for an undeveloped coastal barrier. Therefore, we do not 
recommend remapping to remove the land currently in the CBRS unit 
except for a minor and technical correction to address an error in the 
vicinity of Barton Bay Court (affecting two existing structures) that 
was identified in 2021. We transmitted a draft revised map (dated April 
30, 2021) correcting this minor error to Congress on August 10, 2021. 
That revised map will not take effect unless adopted by Congress 
through legislation. Additional information about this map is available 
on our website at https://www.fws.gov/project/current-coastal-barrier-resources-system-remapping-projects.
    (3.) Comment from the Mayor of the Town of North Topsail Beach, 
North Carolina: The Town supports Representative Murphy's and 
Representative David Rouzer's efforts to exclude from Unit L06 the 
portions of North Topsail Beach serviced by infrastructure. The Town 
asserts that the Service did not consider the full complement of 
infrastructure in place at the time the area was first included in 1982 
within the CBRS.
    Our Response: See above response to Representative Murphy.
    (4.) Comment from the Carteret County Beach Commission, North 
Carolina: Carteret County had no comment regarding the CBRS units in 
North Carolina, as no changes to the current maps are recommended at 
this time.
    (5.) Comment from the National Park Service (NPS): The NPS 
commented in response to the Service's decision that we plan to revisit 
the North Carolina units due to ongoing geomorphic change and the need 
for additional data (including the NPS's completed Cape Hatteras and 
Cape Lookout National Seashores boundary surveys). The NPS provided a 
point of contact for further information about the status of the 
seashore boundary surveys, which were ongoing at the time of the 2022 
5-year review.
    (6.) Comment from the North Carolina Department of Public Safety: 
The State of North Carolina had no comment on the proposed 
modifications. They appreciate the Service's deferral of proposed 
changes in North Carolina due to the dynamic coast and the survey being 
conducted by the NPS.
    (7.) Comment from the Ohio Department of Natural Resources (ODNR): 
The ODNR commented that the proposed change to the southern boundary of 
Unit OH-06 includes a portion of a Federal navigation channel in 
Sandusky Bay. They assert that the existing area is adequate to account 
for potential accretion of the Bay Point sand spit and therefore no 
modification to the existing boundary is needed. However, if the 
boundary is to be modified, ODNR recommends that the proposed boundary 
be adjusted to eliminate inclusion of the Federal navigation channel. 
Additionally, ODNR commented that the revision of the CBRS units is a 
Federal agency activity that will have reasonably foreseeable effects 
on coastal uses and resources in Ohio's coastal zone. As ODNR is the 
designated State agency charged with implementing Ohio's federally 
approved Coastal Management Program under the

[[Page 55712]]

Coastal Zone Management Act (CZMA; 16 U.S.C. 1451-1464 and 15 CFR part 
930), they assert that the Service is required to submit a Federal 
consistency determination to ODNR for this project. After the comment 
period closed, we received an email from the Buffalo District of the 
U.S. Army Corps of Engineers concurring with ODNR's comment.
    Our Response: We reviewed the expansion of Unit OH-06 and agree 
that the proposed change was larger than necessary to account for 
geomorphic change at Bay Point. We have reduced the proposed addition 
to include only the area where accretion is occurring, and the Federal 
navigation channel is no longer proposed for inclusion within the unit. 
However, CBRA does exempt Federal expenditures (following consultation 
between the action agency and the Service) for ``the maintenance or 
construction of improvements of existing Federal navigation channels 
(including the Intracoastal Waterway) and related structures (such as 
jetties), including the disposal of dredge materials related to such 
maintenance or construction'' (16 U.S.C. 3505(a)(2)).
    Regarding ODNR's CZMA comment, the Service has determined that the 
modification of the CBRS boundaries to comply with the statutory 5-year 
review requirement does not require a consistency review under the 
CZMA. Federal agencies are responsible for ensuring that consistency 
review under the CZMA is completed as needed for each action they fund, 
authorize, or carry out. The CZMA's implementing regulations at 15 CFR 
930.31(a) define ``Federal agency activity'' in part as any functions 
performed by or on behalf of a Federal agency in the exercise of its 
statutory responsibilities. The term includes a range of activities 
where a Federal agency makes a proposal for action initiating an 
activity or series of activities when coastal effects are reasonably 
foreseeable (e.g., a Federal agency's proposal to physically alter 
coastal resources, a plan that is used to direct future agency actions, 
a proposed rulemaking that alters uses of the coastal zone). Thus, as 
the CZMA regulation makes clear, the consistency requirement is 
directed at Federal agency activities that result in effects to coastal 
zone resources or uses.
    CBRA encourages the conservation of storm-prone and dynamic coastal 
barriers by requiring that no new Federal expenditures or financial 
assistance be made available within CBRS units unless allowed under 
CBRA. The units were originally designated on a set of maps adopted by 
Congress through legislation, and these maps are maintained by the 
Service. CBRA does not restrict activities conducted with private, 
State, or local funds, and it also contains exceptions that allow 
Federal agencies to fund certain projects and provide financial 
assistance within the CBRS following consultation with the Service.
    Inclusion of areas within the CBRS through the 5-year review (which 
makes minor and technical modifications to existing CBRS units to 
address geomorphic change) results in a requirement that Federal 
agencies ensure that any action they fund, authorize, or carry out is 
compliant with CBRA and its consultation requirement. Even in a case 
where Federal funding for a project is prohibited by CBRA, it may still 
be carried out with an alternative non-Federal funding source. 
Therefore, while we understand the ODNR's position, we have determined 
that the 5-year review is not a Federal agency activity itself, and a 
CZMA Federal consistency review is not needed.
    (8.) Comment from the Town Administrator of the Town of Pawleys 
Island, South Carolina: Pawleys Island commented that there are no 
proposed changes to CBRS Unit M02; however, they have concerns with the 
inclusion of a jetty (located on the south side of Midway Inlet on the 
north end of Pawleys Island) within the current boundary of the unit. 
In particular, the Town requests clarity on the implications of the 
CBRS on making repairs to the jetty, which are anticipated to occur in 
the next couple of years. The Town also requested a meeting with the 
Service to discuss this matter further.
    Our Response: Changes to the CBRS boundaries through the 5-year 
review process are limited to the administrative modifications the 
Secretary is authorized to make under CBRA (16 U.S.C. 3503(c)-(e)). 
Changes that are outside the scope of this authority must be made 
through the comprehensive map modernization process, which requires 
Congressional enactment of legislation to make the revised maps 
effective. Unit M02 has already undergone the comprehensive map 
modernization process, and the revised maps for the unit were adopted 
by Congress via the Strengthening Coastal Communities Act of 2018 (Pub. 
L. 115-358). At that time, the Service carefully reviewed the area 
where the jetty is located, and we determined that the jetty was not 
included within the CBRS as the result of a mapping error.
    Our historical background records indicate that in 1982, when Unit 
M02 was established, the Department of the Interior (Department) was 
aware of the shoreline stabilizing structures (at that time, it was 
rock revetments and a small pile-driven groin) at the north end of 
Pawleys Island. The Department considered the presence of these 
structures and found no basis for excluding the property where the 
structures were located from the CBRS. This issue is addressed in the 
response to Comment 21 in Appendix E of our 2016 Final Report to 
Congress: John H. Chafee Coastal Barrier Resources System Digital 
Mapping Pilot Project. The Service met with the Town Administrator in 
January 2023 to discuss as requested.
    (9.) Comment from FEMA, Region 6, Mitigation Division: FEMA 
requested that we contact the floodplain administrator for the City of 
Rio Grande City, Texas, for the review of this CBRS mapping project 
(including possible permit requirements). In addition, FEMA requested 
that the CBRS mapping project comply with Executive Orders (EOs) 11988 
and 11990 if it is federally funded.
    Our Response: The Service did not contact Rio Grande City, as it is 
over 100 miles inland and our mapping project is along the coast of 
Texas. However, the Service did specifically contact State and local 
officials with floodplain management and/or land use responsibilities 
in the affected areas. Additionally, EOs 11988 and 11990 do not apply 
to the Service's CBRS mapping activities, as there is no associated on-
the-ground activity or financial assistance. Furthermore, CBRA does not 
plan, regulate, or license any land use or development (it merely 
limits the use of Federal funds for certain prohibited activities, with 
no restrictions on private, State, or locally funded projects). CBRA is 
consistent with the spirit of both EOs (which seek to avoid adverse 
impacts associated with the modification or development of floodplains 
and wetlands) because it discourages development and modification of 
coastal barriers and their associated aquatic habitat.
    (10.) Comment from the U.S. Geological Survey (USGS), Coastal/
Marine Hazards and Resources Program: USGS concurred with the CBRS 
review process, indicating that updated imagery detected necessary 
changes resulting from natural processes to a handful of the CBRS 
units. USGS identified some minor inconsistencies between boundaries 
and current imagery in a few cases and a difference in the level of 
fidelity to small-scale features defining boundaries in some areas. 
USGS recommended that boundary changes in submerged areas

[[Page 55713]]

(e.g., Unit WI-04) be more clearly explained.
    Our Response: We met with USGS to discuss the specific issues 
raised. Based on the comments USGS provided, we found that the summary 
of change for Unit WI-04 needed to be updated to provide additional 
explanation for the change. We acknowledge that there are some 
inconsistencies and differences in the level of fidelity to small-scale 
features, due to a variety of reasons. Some inconsistencies were 
inherited from the original mapping of the units in the 1980s and 1990s 
(which was done by hand on 1:24,000 scale USGS topographic 
quadrangles). We are limited in our authority to make administrative 
changes to the boundaries under CBRA (16 U.S.C. 3503(c)-(e)) and cannot 
make changes solely to make the boundaries more consistent with each 
other.
    Additionally, we declined to make changes to certain boundaries 
where there may be a relationship between the boundary and another 
feature (such as a park boundary or an international boundary); This 
can lead to perceived inconsistencies. However, in such cases, further 
review may be warranted through the comprehensive remapping process. 
Furthermore, some changes in the units cannot be addressed through our 
5-year review authority, because they are caused by human activity 
rather than by natural forces.

Changes to Draft Boundaries

    As a result of a stakeholder comment received during the comment 
period, the Service made one change to the boundaries (which were 
displayed on a web mapping application on the Service's website and are 
now depicted on the final revised maps, dated December 30, 2022). This 
boundary change is to Ohio Unit OH-06, and the justification for this 
change is described in the Consultation with Federal, State, and Local 
Officials section of this notice. The remaining CBRS boundaries 
depicted on the final revised maps, dated December 30, 2022, are 
identical to those that were announced for stakeholder review.

Summary of Modifications to the CBRS Maps

    Below is a summary of the changes depicted on the final revised 
maps of December 30, 2022.

Michigan

    The Service's review found that 3 of the 46 CBRS units in Michigan 
required changes due to natural forces. The imagery that was used for 
this review and the revised maps is dated 2020. Additionally, one 
adjustment was needed to the northern lateral boundary of Sadony Bayou 
Unit MI-22 to maintain the relationship between the boundary and a 
structure that was on the ground prior to the designation of the CBRS 
unit in 1990. This structure appeared to be outside of the unit on the 
2012 NAIP imagery used for the previous official map but appears to be 
within the unit on the 2020 imagery due to an approximately 10-foot 
difference in location between the two images. The boundary has been 
adjusted to the south by about 10 feet to maintain the relationship 
between the boundary and the structure that was depicted on the 
previous map, and the structure remains outside of the unit.
    In September 2022, the U.S. Board on Geographic Names voted to 
replace the names of nearly 650 geographic features that had previously 
featured a derogatory word for indigenous women. These name changes 
affect three Michigan units, which have been updated accordingly.
    MI-05: HURON CITY. The boundary of the unit has been modified to 
account for shoreline erosion along Lake Huron to the east of Willow 
Creek.
    MI-13: BIRDSONG BAY. The name of this unit has been changed from 
``Squaw Bay'' to ``Birdsong Bay'' to reflect the new name of the 
underlying feature.
    MI-21: ARCADIA LAKE. The boundary of the unit has been modified to 
account for natural changes along the shoreline of the peninsula 
located between Arcadia Lake and Lake Michigan.
    MI-25: MINO-KWE POINT. The name of this unit has been changed from 
``Squaw Point'' to ``Mino-kwe Point'' to reflect the new name of the 
underlying feature.
    MI-40: GREEN ISLAND. The boundary of the unit has been modified to 
account for shoreline erosion along Lake Michigan at Point la Barbe.
    MI-64: MINO-KWE JIIGIBIIK. The name of this unit has been changed 
from ``Squaw Beach'' to ``Mino-kwe jiigibiik'' to reflect the new name 
of the underlying feature.

Minnesota

    The Service's review found that the boundaries of Unit MN-01 (the 
only CBRS unit in Minnesota) did not need to be modified due to changes 
from natural forces. The imagery that was used for this review and the 
revised map is dated 2021.

Mississippi

    The Service's review found that two of the seven CBRS units in 
Mississippi required changes due to natural forces. The imagery that 
was used for this review and the revised maps is dated 2021.
    R02: DEER ISLAND. The western boundary of the unit has been 
modified to account for accretion at the western end of Deer Island.
    R03: CAT ISLAND. The southern boundary of the eastern segment of 
the unit has been modified to account for accretion of the spit at the 
south end of Cat Island.

North Carolina

    The Service reviewed the 17 CBRS units in North Carolina, but made 
no changes. Revised maps have not been produced for this State. The 
imagery that was used on the currently effective maps is dated 2010, 
2012, or 2014, depending on the unit. The imagery that was used for 
this review is dated 2020.
    While no changes have been made to the CBRS boundaries in North 
Carolina at this time, future changes may be warranted for the 
boundaries of Unit NC-03P, which were updated by Congress in 1999 
through Public Law 106-116 to align with the boundaries of Cape 
Hatteras National Seashore at that time. However, significant shoreline 
erosion has occurred along the Atlantic coast of Hatteras Island, 
particularly in the villages of Rodanthe, Waves, Avon, and Buxton, and 
the CBRS boundary is now hundreds of feet offshore in some places. 
Erosion is occurring at a rate of 2-4 meters per year in some areas.
    In those places where the shoreline has eroded significantly, the 
boundary of Cape Hatteras National Seashore is now the mean high-water 
line. Numerous structures may be located seaward of the mean high-water 
line due to erosion and may be on property owned by the National Park 
Service. Some of these structures have been deemed uninhabitable due to 
compromised septic systems and/or other issues. At the time of our 
review, the National Park Service was planning to conduct a boundary 
survey. As the survey was incomplete before our 5-year review effort 
was completed, we have not made any boundary modifications at this 
time. We will also continue to monitor geomorphic change occurring in 
other areas in North Carolina, including the northwestern boundary of 
Unit L03AP (where geomorphic change is occurring very near to the CBRS 
boundary along Shackleford Banks).
    In the future, we plan to revisit the North Carolina CBRS units 
through the 5-year review authority, provided that sufficient data is 
available at the time of our review. More information about our review 
of North Carolina units can be found in a notice the Service published

[[Page 55714]]

in the Federal Register on November 22, 2022 (87 FR 71352).

Ohio

    The Service's review found that 1 of the 10 CBRS units in Ohio 
required changes due to natural forces. The imagery that was used for 
this review and the revised maps is dated 2021.
    OH-06: BAY POINT. The southern boundary of the unit has been 
modified to account for the southward accretion of Bay Point.

South Carolina

    The Service's review found that 3 of the 10 CBRS units in South 
Carolina that are included in this review (Units M02, M03, M08, M09/
M09P, M10, M13, SC-01, SC-03, and SC-10P) required changes due to 
natural forces. The imagery that was used for this review and the 
revised maps is dated 2021.
    The remaining 13 South Carolina units were not included in this 
review because they were either comprehensively reviewed in 2021 or 
they will be included in a more comprehensive review (beyond the scope 
of the 5-year review) at a later date, at which time the Service will 
also complete an assessment of changes necessary due to natural forces.
    M03: PAWLEYS INLET. The southwestern boundary of the unit has been 
modified to account for natural changes in the wetlands.
    M09: EDISTO COMPLEX. The coincident boundary between Units M09 and 
M09P has been modified to follow the current location of Jeremy Inlet. 
The landward boundary of the unit has been modified to reflect natural 
changes in the configuration of the wetlands along the Townsend River.
    M09P: EDISTO COMPLEX. The coincident boundary between Units M09 and 
M09P has been modified to follow the current location of Jeremy Inlet.

Texas

    The Service's review found that 6 of the 35 CBRS units in Texas 
required changes due to natural forces. The imagery that was used for 
this review and the revised maps is dated 2020.
    T03A: BOLIVAR PENINSULA. The boundary of the unit has been modified 
to reflect natural changes in the configuration of the wetlands on and 
around the Bolivar Peninsula.
    T04: FOLLETS ISLAND. The boundary of the unit (a portion of which 
is coincident with Unit T04P) has been modified to reflect erosion 
along the shorelines of Mud Island and Moody Island.
    T04P: FOLLETS ISLAND. The boundary of the unit (a portion of which 
is coincident with Unit T04) has been modified to reflect erosion along 
the shoreline of Moody Island.
    T07: MATAGORDA PENINSULA. The coincident boundary between Units T07 
and T07P has been modified to account for natural changes at the mouth 
of Caney Creek.
    T07P: MATAGORDA PENINSULA. The coincident boundary between Units 
T07 and T07P has been modified to account for natural changes at the 
mouth of Caney Creek.
    T12: BOCA CHICA. The boundary of the unit has been modified to 
account for natural changes along the shoreline of the Rio Grande.

Wisconsin

    The Service's review found that three of the seven CBRS units in 
Wisconsin required changes due to natural forces. The imagery that was 
used for this review and the revised maps is dated 2020.
    WI-03: PESHTIGO POINT. The southern boundary of the western segment 
of the unit has been modified to account for erosion and an increased 
lake level in Green Bay.
    WI-04: DYERS SLOUGH. The eastern boundary of the unit has been 
modified to account for erosion and an increased lake level in Green 
Bay and maintain a relationship between the boundary and the shoreline 
of the landform at the mouth of the Peshtigo River.
    WI-07: FLAG RIVER. The western boundary of the unit has been 
modified to reflect natural changes in the configuration of the 
wetlands at the mouth of the Flag River.

Availability of Final Maps and Related Information

    The final revised maps dated December 30, 2022, can be accessed and
