South Dakota's Housing Infrastructure Financing Program, a state loan fund intended to incentivize housing construction, will soon be available for airport improvement and maintenance projects in Sioux Falls and Rapid City. The change is part of legislation approved by lawmakers and signed into law by South Dakota Republican Gov. Larry Rhoden. The loans can be used for housing-related infrastructure such as streets, roads, sewer lines and water lines. The fund has supported 85 projects across the state and has supported 7,421 single-family housing lots or units and 5,754 apartment or other multi-family units. The new law will take effect in July. This bill is one of 210 signed by Rhoden during the annual legislative session.
