The Rural Heritage Development Initiative (RHDI) is a three-year pilot program of preservation-based economic development in the 15-county Arkansas Delta region. Focusing on heritage tourism, local business development, preservation education, landmark preservation, and imaging & branding, the RHDI is funded by the W.K. Kellogg Foundation and sponsored by the National Trust for Historic Preservation. Partners in the RHDI are Main Street Arkansas, Arkansas Delta Byways and the Historic Preservation Alliance of Arkansas, as well as the Main Street programs of Blytheville, Dumas, Helena, Osceola and West Memphis.
