Description: The Federal Emergency Management Agency (FEMA) has developed the Advisory Flood Zones. They provide full geospatial representation of the coastal and riverine Advisory Base Flood Elevations (1% annual chance coastal flood hazard), including both storm surge and wave components. FEMA is providing an advisory floodway to provide a geospatial limit of the channel of rivers or other watercourse and the adjacent land areas that must be reserved in order to discharge the base flood without cumulatively increasing the water surface elevation more than the designated height. FEMA has developed the Coastal A Zone to approximate the extent of breaking waves less than 3 ft and equal to and greater than 1.5 ft in height for the 1-Percent-Annual-Chance flood events

Description: 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.
Description: Para los municipios de Puerto Rico se realizaron actualizaciones de las estructuras, teniendo como resultado 35 municipios actualizados con una imagen aérea del 2010. En algunos polígonos no se tenía datos, por este motivo se añadieron unas propiedades estándares para los mismos. Estos polígonos fueron identificados con la columna "Estructuras", en la cual el número 1 representa los datos originales, el número 2 representa los datos estándares y el número 3 para identificar aquellos polígonos que tienen algunos datos originales y otros estándares.
