Brandon sits about five miles east of Sioux Falls in Minnehaha County, where the Big Sioux River meets Split Rock Creek. Interstate 90 runs along the city's north side, and most shops line Splitrock Boulevard (SD Highway 11). A post office named Brandon has operated since 1878, but the city itself only incorporated in 1973.
A young, fast-growing city
Brandon grew from 8,785 residents in 2010 to 11,048 in 2020, and the 2020 census counted 4,038 housing units with only 3.7% vacant. The median age is about 35. Families come for the Brandon Valley School District, which added an intermediate school in 2015 and runs five elementary schools. Weekends often mean Great Bear Recreation Park or the trails and campsites at the Big Sioux Recreation Area.
Newer houses still get tested
South Dakota's Department of Agriculture and Natural Resources places the eastern part of the state in EPA Radon Zone 1, the highest predicted level. Brandon's newer subdivisions are no exception: radon rises from the soil under any slab or basement floor, so a recent build can test high just like an older farmhouse. The state also stresses that the zone map never replaces a test of your own house.
