The objective of this report is to identify high impact areas within Polk County for future investment in affordable housing development. This analysis takes into account areas of existing need in the county as well as areas that are well served by bus service, schools, food markets, and medical facilities. Through a spatial analysis methodology that overlays these two sets of conditions (areas of need and areas with proximity to critical services), we are able to identify optimal areas for the development of new affordable housing in Polk County.
