This is a polygon data set representing City of Boise annexations and de-annexations since the original townsite was established in 1866 by the Idaho Territorial Legislature. An annexation is the legal incorporation of a geographic area in to a political body. A de-annexation is the secession of a geographic area from a political body. De-annexed areas are areas that were once part of the incorporated boundaries of Boise City but have been removed from the incorporated boundaries (based on the ordinance tied to the de-annexation).The source of the data is the ordinances of annexation recorded by the Boise City Clerks' office. This data is maintained by City of Boise GIS and is based on the legal descriptions contained in the ordinances. This data set is continually being updated as annexations occur. It is current to the date it was published.Data Attributes:Ordinance # (ORDINANCE): This is a number, assigned by the Boise City Clerk's Office, which uniquely identifies the codified annexation.Year Approved (ANNEXYEAR): Year the annexation was approved.Official Effective Date (EFFECTIVEDATE): The official date the annexation became effective.Unique ID (ANNEXNUMBER): This is a unique identification code, assigned by Boise City Planning and Development Services, used to track the progression of an annexation prior to the annexation being codified as an official ordinance.Notes (ANNEXNOTES): Miscellaneous information associated with the annexation (i.e. other ordinances that affect that particular ordinance, de-annexed areas). De-annexation (DeAnnexed)? Indicates whether the polygon has been 'de-annexed' or not.For more information about annexations, please contact the City of Boise Planning & Development Services division.
