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.

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 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. 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.

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.

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 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 coincident with Unit FL-47P, located between Little Knockemdown Key and Summerland Key, have been modified to account for natural changes that have occurred in the configuration of the shoreline.

FL-54: SUGARLOAF SOUND UNIT. There are four discrete segments of Unit FL-54, but modifications to account for natural changes were only necessary in the two western segments. In both western segments of the unit, portions of the boundary have been modified to reflect natural changes in the configuration of the shoreline along Lower Sugarloaf Sound.

FL-55: SADDLEBUNCH KEYS UNIT. There are two discrete segments of Unit FL-55. In the northern segment of the unit, portions of the boundary have been modified to account for shoreline erosion along the western side of Shark Key. In the southern segment of the unit, portions of the boundary have been modified to reflect natural changes that have occurred in the configuration of the mangroves and shoreline along Geiger Key.

FL-65P: WIGGINS PASS UNIT. A portion of the landward boundary of the unit has been modified to account for natural changes that have occurred along Vanderbilt Channel.

FL-67: BUNCHE BEACH UNIT. The northern boundary of the unit has been modified to account for natural changes that have occurred in the configuration of an unnamed channel south of Big Shell Island. A portion of the western boundary has been extended westward to account for the migration of the sand sharing system in San Carlos Bay. The name of this unit has been changed from “Bunch Beach” to “Bunche Beach” to correct a spelling error.

FL-80P: PASSAGE KEY UNIT. The northern and southern lateral boundaries of the unit have been extended westward and the southern lateral boundary has been moved southward to ensure that all of the shoals are clearly within the unit.

FL-81: EGMONT KEY UNIT. The boundary of the southern segment of the unit has been modified to account for natural changes that have occurred along the shoreline of Egmont Key.

FL-81P: EGMONT KEY UNIT. The landward boundary of the unit has been modified to account for natural changes that have occurred in the configuration of the shoreline along Egmont Key. The southern boundary has been moved southward to include more of the sand sharing system associated with Egmont Key.

FL-83: COCKROACH BAY UNIT. Portions of the landward boundary of the unit have been modified to account for natural changes that have occurred in the configuration of the wetland/fastland interface.

FL-86P: CALADESI/HONEYMOON ISLANDS UNIT. A portion of the northern boundary of the unit has been moved northward to include more of the sand sharing system associated with Honeymoon Island. A portion of the southern boundary that is coincident with Unit P24A has been modified to account for accretion and to include the associated aquatic habitat at the northern tip of Clearwater Beach Island.

FL-89: PENINSULA POINT UNIT. The landward boundary and the western lateral boundary of the unit have been moved further north and west to account for accretion at the western tip of Peninsula Point. The southern lateral boundary of the unit has been extended offshore to clarify the extent of the unit.

FL-94: DEER LAKE COMPLEX. The westernmost portion of the landward boundary of the unit has been modified to reflect natural changes in the wetlands along the shoreline of an unnamed pond. The boundary following the eastern shoreline of Deer Lake and the boundary along the central segment of the unit have been modified to reflect natural changes that have occurred in the configuration of the wetland/fastland interface.

FL-96: DRAPER LAKE UNIT. A portion of the landward boundary of the unit has been modified to reflect natural changes in the shoreline of Draper Lake.

FL-97: NAVARRE BEACH UNIT. The landward boundary of the unit has been modified to account for shoreline erosion along the northern side of Santa Rosa Sound.

FL-98P: SANTA ROSA ISLAND UNIT. A portion of the boundary in Pensacola Bay, located northwest of Fort Pickens, has been moved northward to account for accretion at the western tip of Santa Rosa Island.

FL-99: TOM KING UNIT. An approximately 750-foot long portion of the boundary of the unit located along the shoreline of East Bay north of Tom King Bayou has been modified to correct an administrative error in the transcription of the boundary from the prior CBRS map dated October 24, 1990, to the official map dated July 12, 1996, for this unit. The boundary on the official 1996 map was placed approximately 130 feet too far inland, and incorrectly included four homes within the unit. This correction is supported by an assessment of the historical CBRS maps for this area, the draft map of Unit FL-99 included in the Service's 1988 Report to Congress: Volume 15, Florida (West Coast); the Service's 1994 Coastal Barrier Resources System Photographic Atlas: Florida, Volume 13, Panama City, Part II; and the legislative history of the Coastal Barrier Improvement Act (CBIA) (Pub. L. 101-591). Structures remain within other portions of Unit FL-99 that were not affected by this transcription error. No modifications were made to the boundaries of this unit as a result of changes due to natural forces.

FL-100: TOWN POINT UNIT. The eastern and western lateral boundaries of the unit have been extended offshore to clarify that the shoals north of Town Point in Pensacola Bay are within the unit. No modifications were made to the boundaries of this unit as a result of changes due to natural forces.

FL-101: GARCON POINT UNIT. A portion of the landward boundary of the unit has been modified to account for natural changes that have occurred in the wetlands. A portion of the northern boundary of the unit has been modified to account for erosion along the shoreline of East Bay and natural changes that have occurred in the configuration of the wetland/fastland interface. An offshore boundary has been added in East Bay, and the western lateral boundary of the unit has been extended offshore to clarify the extent of the unit.

FL-102: BASIN BAYOU UNIT. A portion of the boundary along Escambia Bay has been modified to account for erosion along the shoreline.

FL-103P: PERDIDO KEY UNIT. A portion of the landward boundary at the eastern end of the unit has been moved northward to account for accretion on the northeastern side of Perdido Key.

P02: TALBOT ISLANDS COMPLEX. The northern portion of the boundary has been modified to account for channel migration along Sawpit Creek and Gunnison Cut.

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 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.

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.
