The percentage increased to 14 percent in 1980 and declined slightly to 13 percent in 1990. Pivo, et al. ascribe the drop in the 1980s to the increase in population in exurban bedroom communities. The study concludes by recommending strategies to increase the density and balance of urban areas, first by promoting such increases statewide, second by targeting declining areas, and third by focusing on places that should be denser or more balanced given their regional location. The city of Sioux Falls is located in southeastern South Dakota at the intersection of Interstates 90 and 29. It is the largest city in the state with a population estimate of 114,000 and a two-county MSA population of more than 150.000.
Major employment is centered around medical, retail, finance, and light manufacturing operations.
In 1979, the city of Sioux Falls adopted a comprehensive growth management plan designed to guide urban development over the next 20 years. As part of the plan, growth area boundaries in which development would be permitted were established, based on environmental constraints and the cost and availability of services such as utilities and streets. At the same time, both counties within the MSA were encouraged to adopt stricter zoning ordinances to further manage surrounding rural residential development. In addition, an annexation policy limits services outside corporate limits by annexing areas prior to development approval. Those growth area boundaries established more than 15 years ago have been effectively enforced through phasing of public services and updated land use controls.
