This Flood Insurance Study was produced through a cooperative partnership between the State of North Carolina and FEMA. The North Carolina Floodplain Mapping Program, through FEMA's Cooperating Technical State (CTS) Initiative, is conducting flood hazard analyses and producing updated, digital FIRM panels for all North Carolina communities. Additional information regarding the North Carolina Floodplain Mapping Program and the data collected during the mapping process are available at http://www.ncfloodmaps.com. The Digital Flood Insurance Rate Map (DFIRM) 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 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 file is georeferenced to the earth's surface using the NC State Plane Coordinate System, North American Datum 1983, Units of Feet. The specifications for the horizontal control of DFIRM data files are consistent with those required for mapping at a scale of 1:12,000.

North Carolina Preliminary Stream Centerlines: In 2000, the Federal Emergency Management Agency (FEMA) designated North Carolina a Cooperating Technical Partner State, formalizing an agreement between FEMA and the State to modernize flood maps. This partnership resulted in creation of the North Carolina Floodplain Mapping Program (NCFMP). As a CTS, the State assumed primary ownership and responsibility of the Flood Insurance Rate Maps (FIRMs) for all North Carolina communities as part of the National Flood Insurance Program (NFIP). This project includes conducting flood hazard analyses and producing updated, Digital Flood Insurance Rate Maps (DFIRMs). Floodplain management is a process that aims to achieve reduced losses due to flooding. It takes on many forms, but is realized through a series of federal, state, and local programs and regulations, in concert with industry practice, to identify flood risk, implement methods to protect man-made development from flooding, and protect the natural and beneficial functions of floodplains. FIRMs are the primary tool for state and local governments to mitigate areas of flooding. Individual county databases can be downloaded from https://fris.nc.gov/fris.

Stream Centerlines is a linear feature class that is required for locating all crosssections and for referencing the data from the hydraulic study. These zones are currently in the process of local review and revision.

This data set contains vector polygons depicting locations for counties, EPA regions, Army Corps of Engineers areas, and FEMA regions, and lines depicting state water boundaries in North Carolina. Location-specific type and source information are stored in associated data tables (described below) designed to be used in conjunction with this spatial data layer. This data set is a portion of the...

USA Structures This feature layer, utilizing Federal Emergency Management Agency (FEMA) data, displays footprints for all structures (buildings) greater than 450 square feet in the United States and its territories. According to FEMA, “FEMA’s Response Geospatial Office, Oak Ridge National Laboratory, and the U.S. Geological Survey collaborated to build and maintain the nation’s first comprehensive inventory of all structures larger than 450 square feet for use in Flood Insurance Mitigation, Emergency Preparedness and Response.”Note: these states and territories were updated in this cycle: Alabama, Alaska, Connecticut, Delaware, District of Columbia, Florida, Geogia, Hawaii, Iowa, Kansas, Kentucky, Louisiana, Maine, Michigan, Minnesota, Mississippi, Montana, Nebraska, New Hampshire, New Mexico, New York, North Carolina, North Dakota, Oregon, Rhode Island, South Carolina, South Dakota, Tennessee, Texas, Utah, Vermont, Washington, West Virginia, Wisconsin, Wyoming, Puerto Rico, Virginia, Virgin Islands, Guam, American Samoa, and Northern Mariana Islands.Assembly Building in Dallas County, TexasData currency: June 6, 2025Data source: FEMA's USA Structures State GDB Download SiteData modification: added State FIPS, PROP_CNTY, and Global ID fields.

Information on the amount of water flowing in streams and rivers is critical to the management of water resources, emergency response to flooding, fisheries management, and many other uses. This layer provides access to real-time stream gauge readings compiled from a variety of agencies and organizations.Dataset SummaryThe Live Stream Gauges layer contains real-time measurements of water depth from multiple reporting agencies recording at sensors across the world. This layer uses GeoEvent Processor to ingest and consolidate the many live sensor feeds, and updates itself every hour. At some gauges, flow in cubic feet per second is estimated using a stage-discharge rating curve. Flow forecasts are also provided where available. These sensor feeds are owned and maintained by the GIS community. For details on the coverage in this map and the users who contributed data for this map via the Community Maps Program, view the list of Contributors for the Live Stream Gauges Service. If you want to contribute your organization's gauges, read more about the program here.

This data represents all Fire Department incidents responded to by the Town of Cary. It contains five complete calendar years, plus the current year. The dataset only contains calls that have been completed and reviewed. As a result, incident reports may take 1 - 5 business days to complete, based on the complexity of the call.

Incidents are reported in accordance with the National Fire Incident Reporting System (NFIRS)

This data is updated daily.

The hurricane risk index is simply the product of the cumulative hurricane strikes per coastal county and the CDC Overall Social Vulnerability Index (SVI) for the given county. We normalize the hurricane strikes data to match the SVI data classification scheme (i.e., max value at 1); however, using the raw or normalized values of hurricane strikes has no impact on the spatial pattern of the risk index. Therefore, a risk index of value 1 indicates the county has the highest hurricane strikes of all the counties and is the most vulnerable county in the nation according to the SVI index. Because the analysis is over multiple states, we use the ‘United States’ SVI dataset at the county level. Values of the index are unevenly distributed so we classify intervals using the Jenks method and the first break at 0.08 is roughly equal to the median index value. For counties north of North Carolina, the low hurricane risk is most dependent on the low number of hurricane strikes. The vast majority of the counties fall in the lowest risk category and any in the second lowest category are there because of high social vulnerability.

This data set is a collection of polygons representing the roof line of built structures wholly or partially within the State of North Carolina political boundary. The building footprints are closed polygons with a unique identifier and have the square footage calculated. The polygons were not required to be rectilinear (i.e. interior angles = 90 degrees), but they should give an accurate representation of the building when viewed at a scale of 1:1500 in ArcGIS.

These data were derived by the North Carolina Floodplain Mapping Program (fris.nc.gov) as part of its effort to modernize FEMA Flood Insurance Rate Maps (FIRM) statewide. Previous structure specific geospatial data (where it existed) was typically shown spatially as a point at the center of a structure or parcel boundary. With a building centroid (or center) as a location, much of a building may be within a vulnerable zone of a hazard yet not be included in an evaluation. Good data is extremely important to the hazard assessment. This need for accuracy enhances the need for building footprints to evaluate the hazard. The Statewide Building Footprint Layer was developed to meet that need. The North Carolina Floodplain Mapping Program was established in response to the extensive damage caused by Hurricane Floyd in 1999
