U.S. Fish and Wildlife Service 20161216 B4_CBRS_Polygons Vector Digital Data Set (Polygon) Falls Church, VA U.S. Fish and Wildlife Service This Coastal Barrier Resources System (CBRS) data set, produced by the U.S. Fish and Wildlife Service (Service), contains areas designated as undeveloped coastal barriers in accordance with the Coastal Barrier Resources Act (CBRA), 16 U.S.C. 3501 et seq., as amended. The boundaries used to create the polygons herein were compiled between 12/6/2013 and 12/16/2016 from the official John H. Chafee Coastal Barrier Resources System CBRS maps. The boundaries of the CBRS Units in Connecticut, Massachusetts, Rhode Island, and the Long Island portion of New York, were digitized from the official paper maps according to the guidelines in a notice published in the Federal Register on August 29, 2013 (see the “Georeferencing and Boundary Interpretation” and “Boundary Transcription” sections of 78 FR 53467; available at https://www.federalregister.gov/d/2013-21167). In all other cases where the official map was created through digital methods, the digital boundary was used. These digital polygons are only representations of the CBRS boundaries shown on the official CBRS maps and are not to be considered authoritative. The Service is not responsible for any misuse or misinterpretation of this digital data set, including use of the data to determine eligibility for federal financial assistance such as federal flood insurance. CBRS maps are either enacted by Congress or adopted administratively by the Secretary of the Interior (Secretary), and are maintained by the Service. As maps are revised, this data set will be updated with the new boundaries. Copies of the official CBRS maps are available for viewing at Service’s Headquarters office and are also available to view or download at https://www.fws.gov/ecological-services/habitat-conservation/cbra/Maps/index.html. CBRS boundaries viewed using the CBRS Mapper or the shapefile are subject to misrepresentations beyond the Service’s control, including misalignments of the boundaries with third party base layers and misprojections of spatial data. The official CBRS map is the controlling document and should be consulted for all official determinations. Official determinations are recommended for all properties that are in close proximity (within 20 feet) of a CBRS boundary. For an official determination of whether or not an area or specific property is located within the CBRS, please follow the procedures found at https://www.fws.gov/ecological-services/habitat-conservation/cbra/Determinations.html. For any questions regarding the CBRS, please contact your local Service field office or email CBRA@fws.gov. Contact information for Service field offices can be found at http://www.fws.gov/offices. This data set was created to provide local users with a general depiction of the aerial extent of the boundaries of the John H. Chafee Coastal Barrier Resources System. 19901024 20161216 publication date Complete As needed -97.638831188 -64.623138628 47.435614654 17.66185332 None CBIA Coastal Barrier Resources System Coastal Barrier Coastal Barrier Resources Act Flood Insurance Prohibition CBRS Otherwise Protected Area John H.

Falls Church VA 22041 US 703-358-2171 CBRA@fws.gov Esri ArcGIS 10.2.2 (Build 3552) Service Pack N/A (Build N/A) Independent quality control checks were conducted on all attributes. Topological checks were conducted to ensure that no polygons overlap and that adjacent boundaries are coincident where appropriate. In most cases the seaward boundary of a CBRS unit is defined by the 30 foot bathymetric contour rather than a hard boundary depicted on the official source map. In these cases, the digital boundaries have been terminated by connecting the ends of the lateral boundaries on the seaward side. Therefore, the actual CBRS seaward boundary may extend farther offshore than is shown by the polygons. In large coastal embayments and the Great Lakes, the boundary is defined by the 20-ft bathymetric contour or a line approximately one mile seaward of the shoreline, whichever is nearer the coastal barrier. Because many CBRS boundaries have specific relationships to features visible on the base map, the CBRS boundaries are most reliable when paired with the orthoimagery that was used in the boundary digitization. Therefore, a potential source of error is the spatial accuracy of the base map orthoimagery. The CBRS boundaries inherit the spatial accuracy of base orthoimagery, and may appear not to fit other images properly. The orthoimagery is obtained from multiple sources and is selected based on quality, cost, and coverage availability. The imagery selected generally met the following guidelines: it must be no more than five years old at the time of boundary digitization, it must have a resolution of 1 meter pixels or less, the imagery must be orthorectified, and the imagery must be available free of charge. Commonly used orthoimagery for CBRS mapping is from the National Agriculture Imagery Program (NAIP). NAIP imagery has a stated horizontal accuracy of +/- 20 feet. For official CBRS maps produced since 2014, the base map image source is printed in the title block of the map. To obtain the source of the base map image for a particular map or for other information about CBRS mapping, please email CBRA@fws.gov.

Producer defined Unit_Type String 25 0 0 Fast_Acres The approximate amount of fastlands (also known as uplands), in acres, that is landward of the shoreline of a unit. Land of this type is considered to generally consist of land above mean high tide. The value is derived by calculating the portion of the unit, inland of the shoreline, that is not covered by the National Wetlands Inventory (NWI) polygons. U.S. Fish and Wildlife Service 0 45893 Fast_Acres Single 4 0 0 Wet_Acres The approximate amount of wetlands and open water landward of the shoreline of a unit, in acres. This value is most often derived by calculating the portion of the unit, landward of the shoreline, that contains NWI polygons. The associated aquatic habitat acreage numbers include open water landward of the coastal barrier, but not nearshore waters seaward of the shoreline. For the purpose of the acreage calculation, all units were artificially closed at the seaward shoreline using a dataset digitized for this purpose before acreage calculations were performed. U.S. Fish and Wildlife Service 0 120308 Wet_Acres Single 4 0 0 Shore_Mile The approximate length of shoreline within a unit in miles. The Service digitized a shoreline boundary to artificially close off the units along the seaward shoreline. This shoreline boundary generally follows the wet/dry sand line as interpreted from the base map image. Additionally, the shoreline boundary crosses any inlets and/or other dividing water bodies within each unit. In conjunction with the boundaries of the unit, the shoreline boundary is used to define the total area of a unit that is subject to an acreage calculation.

Chafee Coastal Barrier Resources System (CBRS), a defined set of geographic units along the Atlantic, Gulf of Mexico, Great Lakes, U.S. Virgin Islands, and Puerto Rico coasts. Most new Federal expenditures and financial assistance are prohibited within the CBRS, unless those activities qualify for an exception under Section 6 of CBRA (16 U.S.C. § 3505). The U.S. Fish and Wildlife Service (Service), through the Secretary of the Interior, is responsible for administering CBRA which includes consulting with Federal agencies that propose spending funds within the CBRS. There are two types of units within the CBRS; “System units” and “Otherwise Protected Areas” (OPAs). The boundaries of System units are generally intended to follow geomorphic, development, or cultural features (e.g., wetland/upland interface, roads, etc.) and are depicted on the CBRS maps with bold solid lines. Most new Federal expenditures and financial assistance, including Federal flood insurance, are prohibited within System units. The CBRS currently includes 585 System units, which add up to approximately 1.35 million acres of land and associated aquatic habitat. The boundaries of OPAs are generally intended to coincide with the boundaries of conservation or recreation areas such as state parks and national wildlife refuges. OPAs are depicted on the CBRS maps with dotted/dashed lines and unit names followed by a “P” (e.g., FL-20P). The only Federal spending prohibition within OPAs is the prohibition on Federal flood insurance. The CBRS currently includes 277 OPAs which add up to approximately 2.11 million acres of land and associated aquatic habitat.
