John H. Chafee Coastal Barrier Resources System; Availability of 
Final Revised Maps for Alabama, Florida, Georgia, Louisiana, Michigan, 
Minnesota, Mississippi, New York, Ohio, and Wisconsin

AGENCY: Fish and Wildlife Service, Interior.

ACTION: Notice of availability.

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

SUMMARY: The Coastal Barrier Resources Act (CBRA) requires the 
Secretary of the Interior (Secretary) 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 CBRS unit as a result of natural forces. 
The U.S. Fish and Wildlife Service (Service) has conducted this review 
and has prepared final revised maps for all of the CBRS units in 
Alabama, most units in Florida, all units in Georgia, several units in 
Louisiana, all units in Michigan, the only unit in Minnesota, all units 
in Mississippi, all units in the Great Lakes region of New York, all 
units in Ohio, and all units in Wisconsin. The maps were produced by 
the Service in partnership with the Federal Emergency Management Agency 
(FEMA) and in consultation with the appropriate Federal, State, and 
local officials. This notice announces the findings of the Service's 
review and the availability of final revised maps for 247 CBRS units. 
The final revised maps for these CBRS units, dated January 11, 2016, 
are the official controlling CBRS maps for these areas.

DATES: Changes to the CBRS depicted on the final revised maps, dated 
January 11, 2016, become effective on March 14, 2016.

ADDRESSES: For information about how to get copies of the maps or where 
to go to view them, see SUPPLEMENTARY INFORMATION.

FOR FURTHER INFORMATION CONTACT: Katie Niemi, Coastal Barriers 
Coordinator, U.S. Fish and Wildlife Service, Ecological Services 
Program, 5275 Leesburg Pike, MS: ES, Falls Church, VA 22041; (703) 358-

SUPPLEMENTARY INFORMATION:

Background

    Background information on the CBRA (16 U.S.C. 3501 et seq.) and the 
CBRS, as well as information on the digital conversion effort and the 
methodology used to produce the revised maps, can be found in a notice 
the Service published in the Federal Register on August 29, 2013 (78 FR 
53467).
    For information on how to access the final revised maps, see the 
Availability of Final Maps and Related Information section below.

Announced Map Modifications

    This notice announces modifications to the maps for all of the CBRS 
units in Alabama, most units in Florida, all units in Georgia, several 
units in Louisiana, all units in Michigan, the only unit in Minnesota, 
all units in Mississippi, all units in the Great Lakes region of New 
York, all units in Ohio, and all units in 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). The CBRA 
requires the Secretary to review the CBRS maps at least once every 5 
years and make, in consultation with the appropriate Federal, State, 
and local officials, 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 CBRS unit as a result of 
natural forces (16 U.S.C. 3503(c)).
    The Service's review resulted in a set of 202 final revised maps, 
dated January 11, 2016, depicting a total of 247 CBRS units. The set of 
maps includes: 9 maps for 10 CBRS units located in Alabama, 90 maps for 
125 CBRS units located in Florida, 16 maps for 13 CBRS units located in 
Georgia, 15 maps for 7 CBRS units located in Louisiana, 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, 14 maps for 
21 CBRS units located in the Great Lakes region of New York, 7 maps for 
10 CBRS units located in Ohio, and 5 maps for 7 CBRS units located in 
Wisconsin. Comprehensively revised maps for Florida Units P15, P16 and 
FL-63P were made effective on February 29, 2016, via Public Law 114-
128; therefore, the revised maps prepared for these units through the 
digital conversion effort will not be adopted administratively by the 
Service and are not described in this notice. The Service found that a 
total of 134 of the 247 units reviewed had experienced changes in their 
size or location as a result of natural forces since they were last 
mapped. The Service's review of these areas also found two CBRS units 
that required modifications to correct administrative errors that were 
made in the past on maps for Santa Rosa County, Florida, and Jackson 
County, Mississippi. The revised maps were produced by the Service in 
partnership with FEMA.
    The Service is specifically notifying the following stakeholders 
concerning the availability of the final revised maps: 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; the members of the Senate and House of 
Representatives for the affected areas; the Governors of the affected 
areas; the local elected officials of the affected areas; and other 
appropriate Federal, State, and local officials.

Consultation With Federal, State, and Local Officials

Consultation and Comment Period

    The CBRA requires consultation with the appropriate Federal, State, 
and local officials (stakeholders) on the proposed CBRS boundary 
modifications to reflect

[[Page 13408]]

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 maps 
(dated August 14, 2015) for Federal, State, and local stakeholders, 
from November 17, 2015, through December 17, 2015. This comment period 
was announced in a notice published in the Federal Register (80 FR 
71826) on November 17, 2015.
    Formal notification of the comment period was provided via letters 
to approximately 530 stakeholders, including 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; the members of the Senate and House of Representatives 
for the affected areas; the Governors of the affected areas; the local 
elected officials of the affected areas; and other appropriate Federal, 
State, and local officials.

Comments and Service Responses

    The November 2015 notice specifically solicited comments from 
Federal, State, and local officials. Below is a summary of the 10 
written comments and/or acknowledgements received from stakeholders 
(Federal, State, and local officials) and the Service's response to 
those comments. Comments received from non-stakeholders were not 
considered as part of this process and are therefore not summarized or 
responded to below. Interested parties may contact the Service 
individual identified in the FOR FURTHER INFORMATION CONTACT section to 
make arrangements to view copies of the comments received during the 
stakeholder review period.

Great Lakes Region

    1. U.S. General Services Administration Great Lakes Region: The 
U.S. General Services Administration Great Lakes Regional Office had no 
comment on the proposed boundary changes as a result of natural forces 
to the units in Michigan, Minnesota, Ohio, and Wisconsin.

Florida

    1. Representative Jeff Miller, House of Representatives, 1st 
District, Florida: Representative Miller requested that the Service 
review all information provided by his constituents (local officials) 
supporting technical corrections to both Unit P32 and Unit P32P, and 
take appropriate measures to ensure that any technical errors are 
corrected in the final maps.
    Service Response to Representative Miller: The Service did not 
receive comments from local officials or any other constituents 
regarding Units P32 and P32P during the comment period. However, the 
Service has been contacted by the City of Destin in the past regarding 
whether the areas within these units met the CBRA criteria for an 
undeveloped coastal barrier at the time of designation. Changes to the 
CBRS boundaries through the digital conversion effort are limited to 
the administrative modifications the Secretary is authorized to make 
under the CBRA (16 U.S.C. 3503(c)-(e)). Changes that are outside the 
scope of this authority and technical correction reviews must be 
considered through the comprehensive map modernization process, which 
entails significant research, public review, and Congressional 
enactment of legislation to make the revised maps effective. Additional 
information about CBRS digital conversion and comprehensive map 
modernization can be found in the Digital Conversion of the CBRS Maps 
section of the notice published by the Service in the Federal Register 
on August 29, 2013 (78 FR 53467).
    The Service will consider the information previously provided by 
the local officials at such time as this area is reviewed through the 
comprehensive map modernization process. However, the Service does not 
recommend removing lands or aquatic habitat from the CBRS unless there 
is compelling evidence that a technical mapping error led to the 
inclusion of the area in the CBRS.
    2. Bay County Community Development Department: Bay County provided 
comments regarding three residential subdivisions and Recreational 
Vehicle subdivision in Unit P31P and a portion of a residential 
subdivision and residential/resort condominium in Unit FL-93P. Bay 
County believes these areas were mapped within the OPAs by mistake due 
to their close proximity to State parks (St. Andrews State Park in Unit 
P31P and Camp Helen State Park in Unit FL-93P) and should be removed 
from the CBRS.
    Service Response to Bay County Community Development Department: 
Changes to the CBRS boundaries through the digital conversion effort 
are limited to the administrative modifications the Secretary is 
authorized to make under the CBRA (16 U.S.C. 3503(c)-(e)). Changes that 
are outside the scope of this authority, such as those recommended by 
Bay County, must be considered through the comprehensive map 
modernization process, which entails significant research, public 
review, and Congressional enactment of legislation to make the revised 
maps effective. Additional information about CBRS digital conversion 
and comprehensive map modernization can be found in the Digital 
Conversion of the CBRS Maps section of the notice published by the 
Service in the Federal Register on August 29, 2013 (78 FR 53467).
    Unit FL-93P has already undergone the comprehensive map 
modernization process through the Digital Mapping Pilot Project (pilot 
project) and the results of the Service's initial review of Unit FL-93P 
are contained in Appendix D of the Service's 2008 Report to Congress: 
John H. Chafee Coastal Barrier Resources System Digital Mapping Pilot 
Project. The Service is currently preparing a final recommended map of 
the unit for Congressional consideration. The final results of the 
Service's comprehensive review of Unit FL-93P, including the final 
recommended map, will be included in a final report to Congress on the 
pilot project, which is anticipated to be finalized later in 2016. The 
final recommended map for Unit FL-93P will become effective only if 
adopted by Congress through legislation.
    Unit P31P is currently undergoing the comprehensive map 
modernization process. The Service will consider the information 
provided by Bay County during the course of its review. However, the 
Service does not recommend removing lands or aquatic habitat from the 
CBRS unless there is compelling evidence that a technical mapping error 
led to the inclusion of the area in the CBRS.
    3. St. Johns County Engineering Division: St. Johns County 
commented that the 1996 map (which is dated November 12, 1996) of Unit 
P05 shows the northern boundary of the unit hugging St. Augustine 
Inlet's northern boundary, and that the boundary on the 2015 draft map 
(which is dated August 14, 2015) now cuts through the beach immediately 
north of the inlet. The County indicated that this area has 
historically been dynamic and requested that the northern boundary of 
Unit P05 along Porpoise Point (aka Vilano Point) be revised to hug the 
current location of St. Augustine Inlet's north shoreline.
    Service Response to St. Johns County Engineering Division: The 
Service has reviewed the northern boundary of Unit P05 and has made a 
modification to the portion of the boundary along the eastern shoreline 
of the Tolomato River, but has made no change to the boundary as it 
crosses the barrier north of St.

[[Page 13409]]

Augustine Inlet along Porpoise Point for the reasons described below.
    When Unit P05 was first established in 1982, the northern boundary 
of the unit was drawn to include the undeveloped land located north of 
St. Augustine Inlet. The original map adopted by Congress included 
within the unit approximately 41 lots of a residential subdivision 
(which was beginning to develop at the time of designation) known as 
Porpoise Point. In 1996, Congress revised the northern boundary of Unit 
P05 with the intent of removing these 41 lots from the CBRS by enacting 
Public Law 104-333. According to the legislative history of this law, 
the northern boundary of Unit P05 on the map adopted through this 
legislation was to follow ``the division between developed and 
undeveloped property,'' and there is no mention of the northern 
shoreline of the inlet (House Report 104-452). The fact that the 
boundary on the 1996 map follows the location of the northern shoreline 
of the inlet as depicted on the base map appears to be coincidence. 
Because the intent of this boundary is to follow a development feature, 
rather than a geomorphic feature that has experienced natural change, 
it is outside the scope of the digital conversion effort, which is 
limited to the administrative modifications the Secretary is authorized 
to make under the 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 the revised maps. Additional information about CBRS 
digital conversion and comprehensive map modernization can be found in 
the Digital Conversion of the CBRS Maps section of the notice published 
by the Service in the Federal Register on August 29, 2013 (78 FR 
53467).
    Unit P05 has already undergone the comprehensive map modernization 
process through the Digital Mapping Pilot Project (pilot project) and 
the results of the Service's initial review of Unit P05 are contained 
in Appendix D of the Service's 2008 Report to Congress: John H. Chafee 
Coastal Barrier Resources System Digital Mapping Pilot Project. The 
Service is currently preparing a final recommended map of the unit for 
Congressional consideration. The final results of the Service's 
comprehensive review of Unit P05, including the final recommended map, 
will be included in a final report to Congress on the pilot project, 
which is anticipated to be finalized later in 2016. The final 
recommended map for Unit P05 will become effective only if adopted by 
Congress through legislation.
    The northern boundary of the unit along the Tolomato River located 
just to the northwest of St. Augustine Inlet follows the shoreline on 
the official map dated November 12, 1996, and the Service believes that 
the intent of the boundary in this location was to coincide with the 
shoreline. This change is within the scope of the digital conversion 
project, and the boundary has been modified to follow the current 
location of the shoreline as described in the Summary of Modifications 
to the CBRS Boundaries section below.
    4. Charlotte County Community Development Department: Charlotte 
County had no comments regarding the proposed additions, but requested 
that the Service review the northern portion of the central segment of 
Unit P21, which the County believes does not accurately reflect the 
natural conditions at the time the area was designated within the CBRS 
in 1990. Information provided by the County indicates that the northern 
portion of the central segment of Unit P21 (which is depicted with 
mangrove symbology on the original base map) includes an area of 
fastland on the mainland. This fastland has developed since the area 
was included within Unit P21. The County requested that the Service 
consider amending this section of the CBRS to reflect the natural 
conditions that were in place at the time of the initial designation of 
the area in 1990 and remove the mainland fastland to make it consistent 
with the remainder of this area.
    Service Response to Charlotte County Community Development 
Department: Changes to the CBRS boundaries through the digital 
conversion effort are limited to the administrative modifications the 
Secretary is authorized to make under the CBRA (16 U.S.C. 3503(c)-(e)). 
Changes that are outside the scope of this authority, such as the one 
recommended by Charlotte County, must be made through the comprehensive 
map modernization process, which entails Congressional enactment of 
legislation to make the revised maps effective. Additional information 
about CBRS digital conversion and comprehensive map modernization can 
be found in the Digital Conversion of the CBRS Maps section of the 
notice published by the Service in the Federal Register on August 29, 
2013 (78 FR 53467).
    Unit P21 has already undergone the comprehensive map modernization 
process through the Digital Mapping Pilot Project (pilot project), and 
the results of the Service's initial review of Unit P21 are contained 
in Appendix D of the Service's 2008 Report to Congress: John H. Chafee 
Coastal Barrier Resources System Digital Mapping Pilot Project. The 
Service is currently preparing a final recommended map of the unit for 
Congressional consideration and will take into consideration the 
information provided by Charlotte County. The final results of the 
Service's comprehensive review of Unit P21, including the final 
recommended map, will be included in a final report to Congress on the 
pilot project, which is anticipated to be finalized later in 2016. The 
final recommended map for Unit P21 will become effective only if 
adopted by Congress through legislation.

Louisiana

    1. State of Louisiana Department of Environmental Quality: The 
State of Louisiana had no objection to the proposed modifications.

Michigan

    1. State of Michigan Department of Environmental Quality: The State 
of Michigan had no comment regarding the draft maps.

Ohio

    1. State of Ohio Department of Natural Resources: The State of Ohio 
had no comment on the proposed modifications.

New York

    1. State of New York Office of Parks, Recreation and Historic 
Preservation: The State of New York commends the Service on the digital 
conversion of the CBRS maps for the parks in the Great Lakes portion of 
New York State, and states that the accuracy of the revised maps 
appears correct and usability will be greatly improved.

Wisconsin

    1. State of Wisconsin Department of Administration's Coastal 
Management Program: The State of Wisconsin found the draft maps 
acceptable and had no further comment.

Change to Draft Maps

    The Service made one change to the CBRS boundaries depicted on the 
draft maps dated August 14, 2015, as a result of the fall 2015 comment 
period (November 17, 2015, 80 FR 71826). This change is to Florida Unit 
P05 and is described in the Summary of Modifications to the CBRS 
Boundaries section below and the justification is included in the 
Consultation with Federal, State, and Local Officials section above.

[[Page 13410]]

    The CBRS boundaries depicted on the remaining final revised maps, 
dated January 11, 2016, are identical to the CBRS boundaries depicted 
on the draft revised maps dated August 14, 2015.

Summary of Modifications to the CBRS Boundaries

    Below is a summary of the changes depicted on the final revised 
maps dated January 11, 2016.

Alabama

    The Service's review found 6 of the 10 CBRS units in Alabama to 
have changed due to natural forces.
    AL-01P: PERDIDO KEY UNIT. A portion of the northern boundary of the 
unit has been modified to account for erosion along the shoreline of 
Old River. The western boundary of the unit has been modified to 
account for both erosion and accretion around Florida Point.
    Q01: MOBILE POINT UNIT. There are five discrete segments of Unit 
Q01, but modifications to account for natural changes were only 
necessary in the largest segment. The southern boundary of the excluded 
area has been modified to account for erosion along the shoreline.
    Q01P: MOBILE POINT UNIT. There are four discrete segments of Unit 
Q01P, but modifications to account for natural changes were only 
necessary in the two eastern segments. In the easternmost segment of 
the unit, the eastern boundary has been modified to account for 
shoreline erosion along Oyster Bay. In the eastern central segment of 
the unit, the southern boundary of the excluded area has been modified 
to account for shoreline erosion, and the boundary following the 
northern edge of Little Lagoon has been modified to account for natural 
changes that have occurred in the configuration of the shoreline.
    Q01A: PELICAN ISLAND UNIT. The landward boundary of the unit 
located west of the Isle Dauphine Golf Club has been extended northward 
and westward to account for the migration of Pelican Island into 
Dauphin Island.
    Q02: DAUPHIN ISLAND UNIT. In the eastern segment of the unit, 
located north of Fort Gaines, a portion of the boundary has been 
modified to account for wetlands erosion along the western side of an 
unnamed channel located landward of the southern portion of Little 
Dauphin Island. In the western segment of the unit, located on the west 
end of Dauphin Island, the northern boundary has been moved further 
north to account for the migration of the island. The western boundary 
has been moved further west to account for accretion at the western tip 
of the island.
    Q02P: DAUPHIN ISLAND UNIT. The portions of the boundary 
encompassing the area near North Point and along the Dauphin Island 
Bridge have been expanded to accommodate accreting sand and submerged 
shoals around the northwestern portion of Little Dauphin Island.

Florida

    The Service's review found 66 of the 125 CBRS units in Florida that 
are included in this review to have changed due to natural forces. 
Additionally, the Service's review found that one of these units, FL-
99, contained an administrative error that was made by the Service in 
1997.
    Unit FL-87P was not included in this review because it was remapped 
and referenced in notices the Service published in the Federal Register 
on August 29, 2013 (78 FR 53467) and April 17, 2014 (79 FR 21787). 
Additionally, this review originally included Florida units P15, P16, 
and FL-63P; however, comprehensively revised maps for those three units 
were made effective on February 29, 2016, via Public Law 114-128; 
therefore, the draft maps for those units prepared through the digital 
conversion effort have been superseded and are not included in this 
notice. The comprehensively revised maps, dated February 29, 2016, make 
modifications to the CBRS to remove areas that were inappropriately 
included within the CBRS in the past; add undeveloped areas that 
qualify for inclusion; and also address the natural changes that were 
proposed in the notice published in the Federal Register (80 FR 71826) 
on November 17, 2015.

    FL-03P: GUANA RIVER UNIT. The boundary of the unit has been 
modified to follow the shoreline at the northeastern portion of 
Capos Island. The boundary has been modified to reflect natural 
changes that have occurred in the configuration of the wetland/
fastland interface around portions of Lake Ponte Vedra and east of 
Guana River. A portion of the landward boundary near Spanish Landing 
has been modified to account for channel migration along the 
Tolomato River as visible on the new CBRS base map. The southwestern 
portion of the landward boundary of the unit has been modified to 
reflect natural changes that have occurred in the configuration of 
the wetland/fastland interface.
    FL-06P: WASHINGTON OAKS UNIT. The northwestern portion of the 
landward boundary of the unit has been modified to reflect natural 
changes that have occurred in the configuration of the wetland/
fastland interface.
    FL-14P: PEPPER BEACH UNIT. There are two discrete segments of 
Unit FL-14P. Within the northern segment, primarily the Indian River 
Aquatic Preserve, the southern boundary has been modified along Fort 
Pierce Cut to reflect natural changes that have occurred in the 
configuration of the shoreline.
    FL-16P: JUPITER BEACH UNIT. A portion of the western boundary of 
the unit has been modified to reflect natural changes that have 
occurred in the configuration of the shoreline of an unnamed channel 
near Jupiter Beach Park. A portion of the northern boundary has been 
modified to reflect natural changes that have occurred in the 
configuration of the shoreline of Jupiter Inlet.
    FL-35: NORTH KEY LARGO UNIT. Portions of the landward boundary 
of the unit have been modified to reflect natural changes that have 
occurred in the configuration of the mangroves and the shoreline 
along Little Card Sound. Portions of the boundaries that are 
coincident with Unit FL-35P have been modified to reflect natural 
changes that have occurred in the configuration of the mangroves and 
shoreline along Linderman Creek, Card Sound, Barnes Sound, and the 
Atlantic Ocean. Portions of the boundary coincident with Unit FL-36P 
have been modified to reflect natural changes that have occurred in 
the configuration of the mangroves and shoreline along El Radabob 
Key.
    FL-35P: NORTH KEY LARGO UNIT. There are seven discrete segments 
of Unit FL-35P, but modifications to account for natural changes 
were only necessary in five of the segments. The boundaries of the 
unit are primarily coincident with those of Unit FL-35. In the 
northernmost segment of the unit, located on Linderman Key, a 
portion of the boundary has been modified to reflect natural changes 
that have occurred in the configuration of the mangroves and 
shoreline along Card Sound. In the next segment to the south, a 
portion of the boundary has been modified to reflect natural changes 
that have occurred in the configuration of the mangroves and 
shoreline along Linderman Creek. The western boundary of this same 
segment has been modified to reflect natural changes that have 
occurred in the configuration of the mangroves and shoreline along 
Card Sound. Portions of the central segment, comprised largely of 
Crocodile Lake National Wildlife Refuge, have been modified to 
reflect natural changes that have occurred in the configuration of 
the shoreline along the Atlantic Ocean and Barnes Sound. In the two 
southernmost segments of Unit FL-35P, portions of the boundaries 
have been modified to reflect natural changes that have occurred in 
the configuration of the mangroves and shoreline along the Atlantic 
Ocean. The lateral boundaries of the central segment have been 
extended to clarify the extent of the unit.
    FL-36P: EL RADABOB KEY UNIT. Portions of the western boundary of 
the unit have been modified to reflect natural changes that have 
occurred in the configuration of the mangroves and shoreline along 
Largo Sound. Portions of the boundary coincident with Unit FL-35 
have been modified to reflect natural changes that have occurred in 
the configuration of the mangroves and shoreline along El Radabob 
Key.
    FL-37: RODRIGUEZ KEY UNIT. A portion of the landward boundary of 
the unit has

[[Page 13411]]

been modified to account for shoreline erosion along the Atlantic 
Ocean.
    FL-39: TAVERNIER KEY UNIT. A portion of the northeastern 
boundary of the unit has been modified to account for emergent 
mangroves along Plantation Key. A boundary segment was added to the 
lateral boundaries to clarify that Tavernier Key is located within 
the unit.
    FL-44: TOMS HARBOR KEYS UNIT. Portions of the landward boundary 
of the unit have been modified to reflect natural changes in the 
configuration of the mangroves and shoreline along Toms Harbor.
    FL-47P: KEY DEER/WHITE HERON UNIT. There are 15 discrete 
segments of Unit FL-47P, but modifications to account for natural 
changes were only necessary in 4 segments. Portions of the boundary 
of the largest segment of the unit were modified to account for 
natural changes that have occurred in the configuration of the 
shoreline along Cudjoe Key. Portions of the boundary that are 
coincident with Unit FL-52 have been modified to account for natural 
changes that have occurred in the configuration of the shoreline 
along Big Torch Key. In a central segment, located between Little 
Knockemdown Key and Summerland Key, portions of the boundary that 
are coincident with Unit FL-52 have been modified to account for 
natural changes that have occurred in the configuration of the 
shoreline. Portions of the boundary, located in Upper Sugarloaf 
Sound, have been modified to account for natural changes in the 
configuration of the shoreline along Buttonwood Key.
    FL-50: NO NAME KEY UNIT. Portions of the western boundary of the 
unit have been modified to account for natural changes in the 
configuration of the shoreline along Big Pine Key.
    FL-51: NEWFOUND HARBOR KEYS UNIT. A portion of the eastern 
boundary of the unit has been modified to account for changes in the 
configuration of the mangroves and shoreline of an unnamed island 
located west of Long Beach.
    FL-52: LITTLE KNOCKEMDOWN/TORCH KEYS COMPLEX UNIT. There are two 
discrete segments of Unit FL-52, but modifications to account for 
natural changes were only necessary in the northern segment. A 
portion of the eastern boundary following Niles Channel, which is 
coincident with the excluded area, has been modified to account for 
natural changes that have occurred in the configuration of the 
shoreline. Portions of the northern boundary that are coincident 
with Unit FL-47P have been modified to account for natural changes 
that have occurred in the configuration of the shoreline along Big 
Torch Key. A portion of the southern boundary has been modified to 
reflect natural changes in the configuration of the mangroves and 
shoreline along Summerland Key. Portions of the boundary that are

    MI-44: ALBANY ISLAND UNIT. The western portion of the landward 
boundary of the unit has been modified to reflect natural changes 
that have occurred in the configuration of the wetland/fastland 
interface.
    MI-49: SHELLDRAKE UNIT. A portion of the northern boundary of 
the unit has been modified to reflect natural changes that have 
occurred in the configuration of the shoreline of Betsy River.
    MI-53: VERMILION UNIT. The landward boundary of the unit has 
been modified to reflect natural changes that have occurred in the 
configuration of the wetland/fastland interface and the 
configuration of the shoreline of Twomile Lake.
    MI-62: SAUX HEAD UNIT. The boundary of the unit has been 
modified to reflect natural changes that have occurred in the 
configuration of the shoreline of Saux Head Lake.

Minnesota

    The Service's review found that the boundaries of Unit MN-01 (the 
only CBRS unit in Minnesota) do not need to be modified due to changes 
from natural forces.

Mississippi

    The Service's review found four of the seven CBRS units in 
Mississippi to have changed due to natural forces. Additionally, the 
Service's review found that one of these units, R01A, contained 
administrative errors that were made by the Service in 1990.

    MS-01P: GULF ISLANDS UNIT. The gap between the two discrete 
segments of the

[[Page 13415]]

unit, located near the western tip of Petit Bois Island, has been 
moved to the west due to the migration of Petit Bois Island towards 
Horn Island Pass Channel.
    MS-02: MARSH POINT UNIT. Portions of the landward boundary of 
the unit have been modified to reflect natural changes that have 
occurred in the configuration of the wetland/fastland interface.
    MS-04: HERON BAY POINT UNIT. Three segments of offshore boundary 
have been added to the eastern, western, and southern portions of 
the unit to clarify the extent of the unit. The southern boundary of 
the unit is coincident with the northern boundary of Unit LA-02 in 
Louisiana. No modifications were made to the boundaries of this unit 
as a result of changes due to natural forces.
    R01A: BELLE FONTAINE POINT UNIT. The western boundary of the 
unit has been modified to reflect natural changes in the wetlands 
along Graveline Bay. Additionally, three areas of the unit have been 
modified to correct administrative errors in the transcription of 
the boundary from the draft map that was included in the Service's 
1988 Report to Congress: Volume 17, Mississippi, and was reviewed 
and approved by Congress, to the official map dated October 24, 
1990, for this unit. On the landward side of the unit, the boundary 
on the official 1990 map inaccurately showed more wetlands within 
the unit than the 1988 draft map. Furthermore, the eastern and 
western lateral boundaries of the unit were intended to remain the 
same as those depicted on the original map for this unit dated 
September 30, 1982, which was adopted by Congress with the enactment 
of the CBRA. However, the lateral boundaries were inadvertently 
moved by as much as 950 feet when they were transcribed from the 
1988 draft map onto the new base map used for the official 1990 map. 
These corrections are supported by an assessment of the historical 
CBRS maps for the area and the legislative history of the CBIA. 
These errors likely occurred due to the fact that the boundary shown 
on the draft map that was approved by Congress had to be transcribed 
onto a new base map in 1990 in order to create the official map for 
the unit, and the new base map showed slightly updated natural and 
development features.
    R02: DEER ISLAND UNIT. The official October 24, 1990, map of 
this unit does not include a complete depiction of the western end 
of Deer Island due to the limitations of the base map that was used 
at the time. The western portion of the boundary of the unit goes up 
to edge of the U.S. Geological Survey Topographic Quadrangle that it 
was printed on, and the unit is assumed to extend to the west to 
cover all of Deer Island. A segment of boundary has been added to 
the western end of the unit to match the location of the boundary as 
depicted on the Congressionally adopted map that first established 
this unit, dated September 30, 1982, to clearly show that all of 
Deer Island is within the unit. This clarification is supported by 
an assessment of the historical CBRS maps for this area as well as 
the legislative history of the CBIA. No modifications were made to 
the boundaries of this unit as a result of changes due to natural 
forces.
    R03: CAT ISLAND UNIT. The western segment of the unit has been 
modified to account for erosion of the wetlands on the western side 
of Cat Island. The eastern segment of the unit, consisting of Middle 
Spit, South Spit, and associated shoals, has been modified to 
account for erosion of the wetlands, and erosion and migration of 
the spit. Due to the rapid rate of erosion in this area, some of the 
boundaries have been generalized.

New York

    The Service's review found 15 of the 21 CBRS units in the Great 
Lakes region of New York (the only CBRS units in New York that were 
part of this review) to have changed due to natural forces. Unit NY-60P 
was remapped and referenced in notices the Service published in the 
Federal Register on June 10, 2014 (79 FR 33207), and May 4, 2015 (80 FR 
25314). Other CBRS units in the State of New York were not assessed as 
part of this review. The Long Island region of New York is part of a 
separate comprehensive mapping project related to Hurricane Sandy. 
Draft maps for that project are anticipated to be released for public 
review and comment in 2017.

    NY-62: GRENADIER ISLAND UNIT. The eastern lateral boundary of 
the unit has been modified to account for the accretion of a sand 
spit within the unit.
    NY-64: THE ISTHMUS UNIT. A portion of the boundary of the unit 
along Chaumont Bay has been modified to reflect natural changes that 
have occurred in the configuration of the wetland/fastland 
interface.
    NY-65: POINT PENINSULA UNIT. The landward boundary of the unit 
has been modified to reflect natural changes that have occurred in 
the configuration of the wetland/fastland interface.
    NY-66: HOUNSFIELD UNIT. Two segments of offshore boundary have 
been added to clarify the extent of the unit. No modifications were 
made to the boundaries of this unit as a result of changes due to 
natural forces.
    NY-67: DUTCH JOHN BAY UNIT. Portions of the boundary along the 
shoreline of Stony Island have been modified to account for natural 
changes that have occurred in the configuration of the shoreline.
    NY-68: SHERWIN BAY UNIT. Portions of the boundary located inland 
of Shore Road have been modified to account for natural changes that 
have occurred in the configuration of the shoreline of Sherwin Bay.
    NY-69: ASSOCIATION ISLAND UNIT. The boundary of the unit has 
been modified to account for erosion along the shoreline of 
Association Island.
    NY-72: NORTH POND UNIT. The boundary of the unit has been 
modified to reflect natural changes that have occurred in the 
configuration of the wetland/fastland interface and to account for 
shoreline erosion around North Pond.
    NY-73: DEER CREEK MARSH UNIT. The boundary of the unit around 
the southern half of Deer Creek Marsh has been modified to reflect 
natural changes that have occurred in the configuration of the 
wetland/fastland interface.
    NY-74: GRINDSTONE CREEK UNIT. The landward boundary of the unit 
has been modified to follow the wetland/fastland interface along 
portions of the boundary that previously followed the shoreline of a 
pond which no longer exists as depicted on the base map of the 
October 15, 1992 official CBRS map. A portion of the northern 
lateral boundary has been moved northward to reflect the current 
position of the outlet of Grindstone Creek.
    NY-75: BUTTERFLY SWAMP UNIT. The landward boundary of the unit 
has been modified to reflect natural changes that have occurred in 
the configuration of the wetland/fastland interface around Butterfly 
Swamp.
    NY-76: WALKER UNIT. The landward and southern lateral boundaries 
of the unit have been modified to reflect natural changes that have 
occurred in the configuration of the wetland/fastland interface.
    NY-77: SNAKE SWAMP UNIT. A portion of the eastern boundary of 
the unit located north of Lakeshore Road has been modified to 
reflect natural changes that have occurred in the configuration of 
the wetland/fastland interface.
    NY-79: BLIND SODUS BAY UNIT. The landward boundary of the unit 
has been modified to account for natural changes that have occurred 
in the configuration of the shoreline and wetland/fastland 
interface. The western lateral boundary of the unit has been moved 
southwest to account for erosion along the shoreline of Lake 
Ontario.
    NY-84: MAXWELL BAY UNIT. The boundary of the unit has been 
modified to account for natural changes that have occurred in the 
configuration of the wetland/fastland interface.
    NY-87: BIG SISTER CREEK UNIT. A portion of the landward boundary 
on the northern side of the unit formerly followed the shoreline of 
an unnamed channel that has since migrated southward. This portion 
of the boundary has been modified to follow the wooded vegetation 
line east of the beach.

Ohio

    The Service's review found 6 of the 10 CBRS units in Ohio to have 
changed due to natural forces.

    OH-02: MENTOR UNIT. There are two segments of Unit OH-02, but 
modifications to account for natural changes were only necessary in 
the western segment. Portions of the boundary around Mentor Marsh 
have been modified to reflect natural changes that have occurred in 
the configuration of the wetland/fastland interface.
    OH-03: NORTH POND UNIT. The western end of the landward boundary 
of the unit has been modified to reflect natural changes that have 
occurred in the configuration of the wetland/fastland interface. The 
eastern and western lateral boundaries of the unit have been 
modified to account for erosion along the shoreline of Lake Erie.
    OH-04: OLD WOMAN CREEK. The southern portion of the boundary of 
the unit located north of Ohio State Route 2 has been modified to 
account for natural changes that have occurred in the shoreline 
along Old Woman Creek.

[[Page 13416]]

    OH-06: BAY POINT UNIT. The southwestern boundary of the unit has 
been moved farther southeast to account for the accretion of Bay 
Point.
    OH-09: FOX MARSH UNIT. The landward boundary of the unit has 
been modified to reflect natural changes that have occurred in the 
configuration of the wetland/fastland interface.
    OH-10: TOUSSAINT RIVER UNIT. The landward boundary of the unit 
has been modified to reflect natural changes that have occurred in 
the configuration of the wetland/fastland interface.
