The Development District Association of Appalachia (DDAA) is an organization of 72 Local Development Districts (LDD's) covering parts of twelve states and all of West Virginia in the Appalachian Region. Local Development District is the Appalachian Regional Commission's (ARC) generic name for the multi-county planning and development organizations which from State to State may be otherwise known as regional councils, councils of governments, area development districts, regional development centers, or regional planning commissions.  LDD's are the local partner in the ARC's Federal-State-Local partnership, and they serve the member counties and municipalities within their designated regions in efforts aimed at achieving the goals of the ARC.
