The total area of the Florence community encompasses 131.68 square miles of land and 8.24 square miles of water, reflecting the abundance of lakes, ponds, and wetlands typical of this glacially carved landscape.
Community & economy
Florence embodies the spirit of rural Great Plains living, where agriculture is the cornerstone of the local economy and neighbors rely on one another through the seasons. Farming operations focused on corn, soybeans, wheat, and sunflowers are common throughout the surrounding countryside, and many residents are tied directly or indirectly to the agricultural industry. Daily life in Florence revolves around community gatherings, local schools, and the natural surroundings that provide opportunities for hunting, fishing, and outdoor recreation throughout the year.
Transportation
Florence is accessible via U.S. Highway 212, a major east-west corridor that connects northeastern South Dakota to communities across the region and beyond. State and county roads provide additional access throughout the rural landscape surrounding the community. The nearest commercial airport serving the area is Watertown Regional Airport, located in Watertown, South Dakota, which offers regional flight connections for residents needing air travel.
History
Florence was established as part of the wave of settlement that swept through Dakota Territory in the late nineteenth century, driven largely by the extension of the railroad and the promise of fertile agricultural land. Like many communities in Codington County, Florence grew as homesteaders arrived to farm the productive glacial plains of northeastern South Dakota. Agriculture has remained the defining industry of the area since its founding, shaping both the landscape and the culture of the community across generations.
Did you know?
One of the lesser-known aspects of the Florence area is the remarkable ratio of water to land within its boundaries — with over 8 square miles of water area, the community sits within one of South Dakota's most lake-rich regions, making it a quiet haven for waterfowl hunters and anglers who seek less-traveled fishing spots. This abundance of wetlands also makes the area an important habitat corridor for migratory birds along the Central Flyway, drawing wildlife enthusiasts from across the region each spring and fall.
