--- title: "NFIP Community Layer Comprehensive" method: GET path: "/v1/NfipCommunityLayerComprehensive" tags: ["National Flood Insurance Program"] deprecated: true --- # NFIP Community Layer Comprehensive `GET /v1/NfipCommunityLayerComprehensive` ## Request - Base URL: `https://www.fema.gov/api/open` - URL: `https://www.fema.gov/api/open/v1/NfipCommunityLayerComprehensive` - Auth: none declared - TypeScript: (a function with typed inputs; its response is checked against the schema) > **Deprecated.** This dataset is also known as the 3d layer and contains a fairly comprehensive set of unaltered source geometry polygons that overlap. It is derived from Census, State of Maine, and National Flood Hazard Layer political boundaries. The Community Layer datasets contain geospatial community boundaries associated with Census and NFIP data. The dataset does not contain personally identifiable information (PII). The Community Layer can be used as a reference to tie Community ID numbers (CID) to jurisdiction, tribal, and special land use area boundaries. However, as jurisdictions may change over time, this dataset should not be considered authoritative. A geodatabase (GDB) link is included in the Full Data section below. The compressed file contains a collection of files that can store, query, and manage both spatial and nonspatial data using software that can read such a file. It contains all three versions of the community layer, not just the layer for which this dataset page describes. Data as of December 2024. No updates are planned at this time. This layer can also be accessed from the FEMA ArcGIS viewer online: https://fema.maps.arcgis.com/home/item.html?id=4b712b99d43d41cb9328e94891520a63 Citation: FEMA's citation requirements for datasets (API usage or file downloads) can be found on the OpenFEMA Terms and Conditions page, Citing Data section: https://www.fema.gov/about/openfema/terms-conditions.

It assists in quickly identifying specific communities and associated flood risk information when using FEMA's management systems. - `stateCode` string, string, nullable: FIPS two-digit numeric code used to identify the United States, the District of Columbia, US territories, outlying areas of the US and freely associated states - `countyCode` string, string, nullable: FIPS five-digit numeric code used to identify counties and county equivalents in the United States, the District of Columbia, US territories, outlying areas of the US and freely associated states. Please note that Indian Reservations are not counties and thus will not have a FIPS county code. - `censusGeoid` string, string, nullable: Numeric code that uniquely identify all administrative/legal and statistical geographic areas for which the Census Bureau tabulates data. - `county` string, string, nullable: The name of a U.S. county, parish, borough, independent city or other political subdivision of a U.S. state or territory - `communityName` string, string, nullable: Name of the NFIP community, generally, representing the lowest level of government with land use authority. Not every city or town is recognized as its own community with the NFIP. Each state or territory determines land use authority granted to counties/parishes/boroughs, towns/cities, tribal area, etc. within their own jurisdiction - `communityNameShort` string, string, nullable: A shortened version of the Community Name - stripped of any suffix such as "Town of" - `censusYear` number, nullable: The Census Year associated with the data. - `censusPopulationEntire` number, nullable: Census Population derived from blocks: Entire Community - `censusHousingUnitsEntire` number, nullable: Census Housing Units derived from blocks: Entire Community - `landAreaEntire` number, float, nullable: Land area of an entire community in square kilometers. - `cisType` string, string, nullable: CIS Government Unit (Derived from CIS Name) - `cisSource` string, string, nullable: Source of CIS data; typically PIVOT - `geometrySource` string, string, nullable: Source of geometry - `alternateGeoid` string, string, nullable: Alternate non-census identifier, such as Maine GIS code - `alternateName` string, string, nullable: Alternate non-census name - `alternateLongName` string, string, nullable: Alternate Long Name - `layerCreationNotes` string, string, nullable: Assumptions or tidbits of note in the creation of the layer - `censusClassCodes` string, string, nullable: Census Class codes: https://www.census.gov/library/reference/code-lists/class-codes.html - `censusFunctionalStatusCodes` string, string, nullable: Census Functional status codes: https://www.census.gov/library/reference/code-lists/functional-status-codes.html - `layerTypeCode` string, string, nullable: Includes the following types: Tribe, County, Consolidated City, Statistical Area, SLUA, Place (multi-county), Maine Town/Township, County Subdivision, Place - `layerGeometry` object, nullable: Polygon or multipolygon coordinates of the layer that the community area encompases. --- [API](https://skmtc.dev/fema/apis/openfema-api.md) - [All operations](https://skmtc.dev/fema/apis/openfema-api/llms.txt) - [OpenAPI document](https://skmtc.dev/fema/apis/openfema-api/revisions/fdc02603897f?raw)
