The entire Vermont extent of the National Flood Hazard Layer (NFHL) as acquired 12/15/15 from the FEMA Map Service Center msc.fema.gov upon publication 12/2/2015 and converted to VSP.The FEMA DFIRM NFHL database compiles all available officially-digitized Digital Flood Insurance Rate Maps. This extract from the FEMA Map Service Center includes all of such data in Vermont including counties and a few municipalities. This data includes the most recent map update for Bennington County effective 12/2/2015.DFIRM - Letter of Map Revision (LOMR) DFIRM X-Sections DFIRM Floodways Special Flood Hazard Areas (All Available)

The National Flood Hazard Layer (NFHL) is a geospatial database that contains current effective flood hazard data. FEMA provides the flood hazard data to support the National Flood Insurance Program. You can use the information to better understand your level of flood risk and type of flooding.

The NFHL is made from effective flood maps and Letters of Map Change (LOMC) delivered to communities. NFHL digital data covers over 90 percent of the U.S. population. New and revised data is being added continuously. If you need information for areas not covered by the NFHL data, there may be other FEMA products which provide coverage for those areas.

NSGIC Data Citation:This project uses existing FEMA data resources that are the authoritative sources of information on this topic, including geospatial data files and open data APIs that were used to access available FEMA Federally-declared Natural Disaster data in the United States available from 1964 to 2014 (through 2013).To support our mapping needs, NSGIC downloaded a snapshot of FEMA data and published our own data Service Definitions and Feature Layers on NSGIC’s ArcGIS Online Mapping Platform to create the unfiltered Feature Layer Services we needed to support our mapping needs of the FEMA Federally Declared Disaster data.Note: These original data sources reflect a variety of inconsistencies and completeness is data collection, as well as changing definitions and priorities in FEMA’s disaster declaration information collection since record-keeping began in 1964. The original data was not modified.To publish the new Feature Layers on ArcGIS Online, NSGIC joined the FEMA Natural Disaster data with an Esri US County polygon shapefile with county population and demographic attributes from the U.S. Census Bureau’s American Community Survey. NSGIC added the 2010 and 2015 population estimates from the Census Bureau’s American Community Survey to relate the impacts of every declared natural disaster to current time frame.A significant portion of the available attribute data is not displayed in the NSGIC interactive maps, but is accessible through the site by experienced users.More recent data may be available from the original sourcesFEMA Data Citation:Data for this project was downloaded from FEMA in April 2016 and reflects the data available at that time using the available APIs.This product uses the Federal Emergency Management Agency’s API, but is not endorsed by FEMA.FEMA cannot verify the quality and/or timeliness of any data or any analysis derived therefrom after the data has been retrieved from FEMA.gov.NSGIC Data Citation:This project uses existing FEMA data resources that are the authoritative sources of information on this topic, including geospatial data files and open data APIs that were used to access available FEMA Federally-declared Natural Disaster data in the United States available from 1964 to 2014 (through 2013).To support our mapping needs, NSGIC downloaded a snapshot of FEMA data and published our own data Service Definitions and Feature Layers on NSGIC’s ArcGIS Online Mapping Platform to create the unfiltered Feature Layer Services we needed to support our mapping needs of the FEMA Federally Declared Disaster data.Note: These original data sources reflect a variety of inconsistencies and completeness is data collection, as well as changing definitions and priorities in FEMA’s disaster declaration information collection since record-keeping began in 1964.

Technical GIS users can also utilize a series of dedicated GIS web services that allow the NFHL database to be incorporated into websites and GIS applications. For more information on available services, go to the NFHL GIS Services User Guide.You can also use the address search on the FEMA Flood Map Service Center (MSC) to view the NFHL data or download a FIRMette. Using the “Search All Products” on the MSC, you can download the NFHL data for a County or State in a GIS file format. This data can be used in most GIS applications to perform spatial analyses and for integration into custom maps and reports. To do so, you will need GIS or mapping software that can read data in shapefile format.FEMA also offers a download of a KMZ (keyhole markup file zipped) file, which overlays the data in Google Earth™. For more information on using the data in Google Earth™, please see Using the National Flood Hazard Layer Web Map Service (WMS) in Google Earth™.

The National Flood Hazard Layer (NFHL) data incorporates all Flood Insurance Rate Map (FIRM) databases published by the Federal Emergency Management Agency (FEMA), and any Letters of Map Revision (LOMRs) that have been issued against those databases since their publication date. It is updated on a monthly basis. The FIRM Database is the digital, geospatial version of the flood hazard information shown on the published paper FIRMs. The FIRM Database depicts flood risk information and supporting data used to develop the risk data. The primary risk classifications used are the 1-percent-annual-chance flood event, the 0.2-percent-annual-chance flood event, and areas of minimal flood risk. The FIRM Database is derived from Flood Insurance Studies (FISs), previously published FIRMs, flood hazard analyses performed in support of the FISs and FIRMs, and new mapping data, where available. The FISs and FIRMs are published by FEMA. The NFHL is available as State or US Territory data sets. Each State or Territory data set consists of all FIRM Databases and corresponding LOMRs available on the publication date of the data set. The specification for the horizontal control of FIRM Databases is consistent with those required for mapping at a scale of 1:12,000. This file is georeferenced to the Earth's surface using the Geographic Coordinate System (GCS) and North American Datum of 1983.

This is a dataset download, not a document. The Open button will start the download.This data layer is an element of the Oregon GIS Framework. This feature dataset contains the following feature classes: 1. FEMA Flood Insurance Study base flood elevation (BFE) lines: The FEMA_BFE feature class is a compilation of FEMA Flood Insurance Study base flood elevation (BFE) lines for the state of Oregon. The FEMA Flood Insurance Study base flood elevation (BFE) lines were derived from Digital Flood Insurance Rate Maps and georeferenced paper Flood Insurance Rate Maps. 2. FEMA Flood Insurance Study inundation zones: The FEMA_FLD_HAZ_AR feature class is a compilation of FEMA Flood Insurance Study inundation zones for the state of Oregon. The FEMA Flood Insurance Study inundation zones were derived from Digital Flood Insurance Rate Maps and georeferenced paper Flood Insurance Rate Maps. 3. FEMA Letter of Map Change (LOMC) Locations: The FEMA_LOMC feature class is a compilation of FEMA Letter of Map Change (LOMC) Locations for the state of Oregon. The FEMA Letter of Map Change (LOMC) Locations were downloaded from the FEMA Map Service Center Website. The LOMC points were precisely located using county-level assessor data, orthoimagery, and lidar hillshades. 4. FEMA Flood Insurance Study profile baselines: The FEMA_PROFIL_BASLN feature class is a compilation of FEMA Flood Insurance Study profile baselines for the state of Oregon. The FEMA Flood Insurance Study profile baselines were derived from Digital Flood Insurance Rate Maps and paper Flood Insurance Rate Maps. 5. FEMA Flood Insurance Study cross section (XS) lines: The FEMA_XS feature class is a compilation of FEMA Flood Insurance Study cross section (XS) lines for the state of Oregon. The FEMA Flood Insurance Study cross section (XS) lines were derived from Digital Flood Insurance Rate Maps and paper Flood Insurance Rate Maps. See feature class metadata for detailed information about each feature class.

The National Household Survey (NHS) tracks progress in personal disaster preparedness through investigation of the American public's preparedness actions, attitudes, and motivations. FEMA administers the survey in English and Spanish via landline and mobile telephone to a random sampling of approximately 5,000 adult respondents. The survey includes a nationally representative sample as well as hazard-specific oversamples which may include earthquake, flood, wildfire, hurricane, winter storm, extreme heat, tornado, and urban event. FEMA delays publishing the data until approximately the release of the summary results for the subsequent NHS iteration. For example, FEMA published the 2017 data package at approximately the same time as the publication of the 2018 NHS Summary.Each zip file may include an analysis summary, the survey instrument, raw weighted and unweighted data, aggregated data analysis, and a codebook with weighting overviews.Raw Data: Datasets may include unedited raw data. As such, users should plan to clean the data as needed prior to analysis.Citation: Users should cite the date the data was accessed or retrieved from fema.gov. In addition, users must clearly state that "FEMA and the Federal Government cannot vouch for the data or analyses derived from these data after the data have been retrieved from the Agency's website.”

Normally, any FIRM that has associated flood profiles has cross sections. The S_XS table contains information about cross section lines. These lines usually represent the locations of channel surveys performed for input into the hydraulic model used to calculate flood elevations. Sometimes cross sections are interpolated between surveyed cross sections using high accuracy elevation data. Depending on the zone designation (Zone AE, Zone A, etc.), these locations may be shown on Flood Profiles in the FIS report and can be used to cross reference the Flood Profiles to the planimetric depiction of the flood hazards. This information is used in the Floodway Data Tables in the FIS report, as well as on the FIRM panels.

This layer is a component of Region Preliminary Data.

Overview: FEMA and Argonne National Laboratory completed the first analysis of community resilience indicators in 2018 and repeated the process in 2022. The analysis process begins with a literature review and cataloguing of published peer-reviewed assessment methodologies on social vulnerability and community resilience. The literature review findings are then filtered by inclusion criteria established by the research team to ensure the methodologies are:

Quantitative, Data and methodology are publicly available, Calculated at the county level or lower, Examine generalized hazard risk (rather than a singular hazard), and Focused on pre-disaster community conditions.

After this, the research team identifies the commonly used indicators across these methodologies and selects the best data source for each indicator. Finally, the research team bins the data for visualization, conducts a correlation analysis, and creates a composite index called the "FEMA Community Resilience Challenges Index (CRCI)".

In 2022, the FEMA and Argonne research team updated the 2018 literature review and examined 14 methodologies published between 2003 and 2021. Examining the indicators used in these methodologies, the research team identified 22 indicators as commonly used (indicators used in five or more of the 14 methodologies). The research team produced the FEMA CRCI at the county and the census tract levels. More details on these indicators and the research process can be found in the FEMA CRCI Storymap. Data last updated on May 13, 2023. This is the latest available version of the CRCI. Questions or comments about this layer? Email the RAPT team at FEMA-TARequest@fema.dhs.gov

This dataset is an input to several tutorials for the software package an UNcertain Structure and Fragility Ensemble (UNSAFE) framework for property-level flood risk esimation. We upload this dataset as this persistent and unique link so that the UNSAFE examples are easier to follow, as the original data is only available at a URL.

This dataset was obtained in April, 2024 on the FEMA Flood Map Service Center: Welcome landing page.

This is a MD iMAP hosted service. Find more information on http://imap.maryland.gov. The DFIRM Database presents the flood risk information depicted on a given Flood Insurance Rate Map (FIRM) in a digital format suitable for use in electronic mapping applications. The DFIRM database is a subset of the Digital Flood Insurance Study (FIS) database that serves to archive the information collected during the FIS. This map service is a composite of Effective and Preliminary floodplain data. Q3 data is used where neither Effective or Preliminary data is available for a given community. The primary risk classifications used are the 1-percent-annual-chance flood event - the 0.2-percent-annual- chance flood event - and areas of minimal flood risk. The DFIRM Database is derived from Flood Insurance Studies (FISs) - previously published Flood Insurance Rate Maps (FIRMs) - flood hazard analyses performed in support of the FISs and FIRMs - and new mapping data - where available. The FISs and FIRMs are published by the Federal Emergency Management Agency (FEMA). The specifications for the horizontal control of DFIRM data files are consistent with those required for mapping at a scale of 1:12 - 000.

The Integrated Public Alert and Warning System (IPAWS) is a modernization of the nation's alert and warning infrastructure that unifies the United States' Emergency Alert System (EAS), Wireless Emergency Alerts (WEA), the National Oceanic and Atmospheric Administration (NOAA) Weather Radio, and other public alerting systems implemented as a set of Web services. Organized and managed by FEMA, the system supports alert origination by Federal, state, local, territorial and tribal officials, and subsequent dissemination to the public using a range of national and local alerting systems. This dataset contains recent, historic, and archived IPAWS Common Alerting Protocol (CAP) v1.2 messages from June 2012 to the present including date, time, event code (examples listed below), city, county, joint agency, police, law enforcement, Collaborative Operating Group (COG), State(s), locality, territory or tribe. It can be used to capture and analyze historic and archived messages. The dataset is published with a twenty-four (24) hour delay to reduce the risk of being confused with an active alert received from the live IPAWS feed. The most recent record will reflect the alert(s) sent twenty-four (24) hours ago (if such records exist). For example, if an alert originator sent an alert at 1459GMT on June 1st and sent a different alert at 1600GMT on June 2nd, these alerts will not be visible in the dataset until 1459GMT on June 2nd and 1600GMT June 3rd respectively. Information on signing up for receiving active alerts can be found at https://www.fema.gov/emergency-managers/practitioners/integrated-public-alert-warning-system . To request access to alerts issued through IPAWS or for a list of companies with access to the IPAWS All-Hazards Information Feed, email ipaws@fema.dhs.gov. The data elements within the CAP messages are well documented and can be found in the following technical document: https://docs.oasis-open.org/emergency/cap/v1.2/CAP-v1.2-os.pdf See also: IPAWS Architecture - https://www.fema.gov/pdf/emergency/ipaws/architecture_diagram.pdf IPAWS Overview - https://www.fema.gov/emergency-managers/practitioners/integrated-public-alert-warning-system This is raw, unedited data with no personally identifiable information from the IPAWS Alert Aggregator from June 2012 to the present created by over 1450 Alert Originators across the country. FEMA does not validate the content of each message. As such, it may contain a small percentage of human error. OpenFEMA does not have a full backup capability so if the site goes down, the information will be inaccessible. This is a rare occurrence. Earlier messages may contain non-compliant geocoordinates. Recent versions of the software check these coordinates for compliance. This dataset is not intended to be an official federal report and should not be considered an official federal report. If you are using this site for other than research purposes, please understand that these CAP messages are captured only after the official IPAWS message has been sent. Note that the original IPAWS CAP message is provided in the originalMessage element of the returned JSON object. The XML based message is encoded such that a separate tool, such as a JSON parser, computer language, or browser must be used to view the original format. See the originalMessage field description for additional details. Due to its size and its hierarchical data structure, working with the IPAWS Archived Alerts file can be challenging. See the OpenFEMA Guide to Working with Large Data Sets page for useful hints and tips: https://www.fema.gov/about/openfema/working-with-large-data-sets .
