 From the Kelo.com News Center, I'm Tom Rooney. The Sioux Falls metro area crossed a new milestone. Here's Joe Bowman with the details. According to the U.S. Census Bureau, the Sioux Falls metropolitan area has surpassed a population threshold of 300,000 residents. The growth surge has led to a sharp increase in property values, but also in property tax. Construction in Sioux Falls is also booming to keep up with the increased demand in housing.
