Sioux Falls annexations

Most Sioux Falls annexations begin with a petition from the property owners; the city council then adopts a resolution taking the territory in, and the resolution is filed with the county Register of Deeds. The city can also annex on its own motion. Every record below carries the petition number for the owners’ request.

An annexation is a boundary change. Whether anything is built on the land afterwards is not part of this record, and the status below is reproduced exactly as the city’s dataset states it. Dates are the date the resolution was filed — the council adopted it earlier.

26 records published , covering 1,279.2 acres .

That counts what 605Buzz has published, not everything the city has annexed. The area is the total of the boundary polygons in these records — the city’s own GIS measurement, which includes street right-of-way annexed alongside the land, and which is not a deeded acreage.
