Layer Type: Polygon Data Owner: FEMA Authoritative: Yes Downloadable: Yes Initial Dataset Creation: Unknown Last update: N/A Update Frequency: N/A Reason for Update: City does not maintain Filters Applied: Flood hazard areas Source data: https://las-cruces.maps.arcgis.com/home/item.html?id=5f1906fd247244e8b1eef0212d0fa290 Projected Coordinate System: N/A Limitations: Overview The National Flood Hazard Layer (NFHL) dataset represents the current effective flood data for the country, where maps have been modernized. It is a compilation of effective Flood Insurance Rate Map (FIRM) databases and Letters of Map Change (LOMCs). The NFHL is updated as studies go effective. For more information, visit FEMA's Map Service Center (MSC). You can view this information in a standalone viewer here: https://hazards-fema.maps.arcgis.com/apps/webappviewer/index.html?id=8b0adb51996444d4879338b5529aa9cd REST URL: https://hazards.fema.gov/gis/nfhl/rest/services/public/NFHL/MapServer Base Map Considerations The default base map is from an ESRI service and conforms to FEMA's specification for horizontal accuracy. This base map is composed of the orthoimagery used when the Flood Insurance Rate Maps (FIRMs) were initially created combined with standard imagery products managed by ESRI. This map should be considered the best online resource to use for official National Flood Insurance Program (NFIP) purposes when determining locations in relation to regulatory flood hazard information. If a different base map is used with the NFHL, the accuracy specification may not be met and the resulting map should be used for general reference only, and not official NFIP purposes.
