Regional Planning Affiliation 18 (RPA-18)

The State of Iowa has 18 Regional Planning Affiliations (RPAs) that provide transportation planning on a regional level outside the urbanized areas.  RPA-18 is comprised of Harrison, Mills, Shelby, and the non-urbanized portion of Pottawattamie County in southwest Iowa. MAPA serves as the RPA facilitator for RPA-18. This planning work includes the development and maintenance of the RPA's Long Range Transportation Plan, Regional TIP, other Iowa DOT requirements, as well as professional and administrative services for the RPA. The RPA-18 Board has separate Policy and Technical Committees, comprised of representatives from each county (Harrison, Mills, Pottawattamie and Shelby) and each city with a population greater than 5,000 (currently the city of Glenwood). The Southwest Iowa Transit Agency (SWITA) and the Iowa DOT are also represented on the Technical Committee.
