2023-08

  • Emergency Management Performance Grants [Bi-Annual Refresh]

2023-06

  • NFIP Community Status Book [New]

2023-05

OpenFEMA API framework version 8.1 has been released. This release includes updates to four existing datasets, and the deprecation of two datasets:

  • Declaration Denials [Update] – A “Tribal Request” flag was added to indicate requests submitted directly to the President, independently of a state, by a Tribal Nation.
  • Disaster Declarations Summaries [Update] – A “Tribal Request” flag was added to indicate requests submitted directly to the President, independently of a state, by a Tribal Nation.
  • FIMA NFIP Redacted Policies Version 2 [Update] – This is a new version of the previous dataset. It contains many additional fields, field name and data type changes, and enhanced field descriptions. These fields have been added to the Policies file: Policy Status, Cancellation/Voidance Reason Code, Subsidized Rate Type, ICC Premium, Reserve Fund Assessment, Community Probation Surcharge, Premium Payment Indicator, Replacement Cost, Basic Building Rate, Additional Building Rate, Basic Contents Rate, Additional Contents Rate, Enclosure Type Code, Building Description Code, Insurance to Value Code, Post-FIRM V Zone Indicator, Floodproofed Indicator, Waiting Period Type, Rollover/Transfer Code, Endorsement Effective Date, FEMA Region, Property Purchase Date, Rental Property Indicator, Tenant Indicator, State-Owned Indicator, Condominium Coverage Type Code, Disaster Assistance Coverage Required Code, Mandatory Purchase Flag, Grandfathering Type Code, Rated NFIP Community ID, Current NFIP Community ID, Rated NFIP Community Name, Program Type Indicator, Map Panel Number, Map Panel Suffix, Census Block Group FIPS, and Current Flood Zone. Version 1 is deprecated and will be removed in September 2023.
  • FIMA NFIP Redacted Claims Version 2 [Update] – This is a new version of the previous dataset. It contains many additional fields, field name and data type changes, and enhanced field descriptions. These fields have been added to the Claims file: Building Damage Amount, Building Deductible Code, Net Building Payment Amount, Building Property Value, Cause of Damage, Condominium Coverage Type Code, Contents Damage Amount, Contents Deductible Code, Net Contents Payment Amount, Contents Property Value, Disaster Assistance Coverage Required Code, Event Designation Number (EDN), Flood Insurance Claims Office (FICO) Number, Flood Characteristics Indicator, Flood Water Duration, Floodproofed Indicator, Flood Event, ICC Coverage, Net ICC Payment Amount, Rated NFIP Community ID, Current NFIP Community ID, Rated NFIP Community Name, Contents Non-Payment Reason, Building Non-Payment Reason, Number of Units, Building Replacement Cost, Contents Replacement Cost, Replacement Cost Basis, State-Owned Indicator, Water Depth, Census Block Group FIPS, Current Flood Zone, Building Description Code, Rental Property Indicator. Version 1 is deprecated and will be removed in September 2023.

In addition to the new datasets, dataset updates, general bug fixes, and performance improvements, version 8.1 of the API framework also includes the following notable changes/fixes:

  • Fixed an error related to browser downloads when using the $filename API parameter.
  • Fixed an issue that caused the API $filter to fail if the sought value contained a forward slash (/).
  • The maximum limit for returned records ($top) has been expanded. Previously, the default number of records returned and the maximum that could be returned at one time was 1,000. Now, if no $top value is specified, 1,000 records will be returned. However, the maximum limit has been increased to 10,000 records. This should reduce the number of situations in which “paging” must be performed to download larger datasets and will reduce the number of iterations for situations where paging is still required. This value may be expanded in the future after we assess the impact to our systems.

2023-04

  • Emergency Management Performance Grants [Bi-Annual Refresh]
  • FY2022 Preparedness (Non-Disaster) / Assistance to Firefighter Grants [Yearly Update]

2023-03

OpenFEMA API framework version 8.0 has been released. In addition to general bug fixes and performance improvements, version 8.0 of the API framework addresses the following:

  • Invalid/unsupported query string parameters will no longer be accepted. An error will be returned indicating the invalid parameter.
  • Changes to the handling of $filter argument data types. The values provided for a filter argument must be quoted or not quoted according to the field data type. The new framework logic will not allow strings for Booleans. Only a Boolean value or a number corresponding to a Boolean (i.e., true/false 0/1) will be accepted. Similarly, numeric values like fiscal years will fail if expressed as a string instead of a number.
  • Enhanced error messaging when query strings are invalid.
  • Fixed an error related to the JSONA file format.
  • Introduced JSONL as a new file format which will be particularly useful for streaming data.
  • The returned field order is now specified by a metadata element. Prior to this version, fields were returned in no particular order. Your processes may be affected if they expected a specific field order. One possible workaround is to use the $select parameter to specify the field order you prefer.
