Abstract: Strategic turns in regional development are a serious challenge. They lead to actions related to the rationalisation of the management of administrative units and territorial systems, to their linking in order to seek synergistic effects. The article deals with a problem related to the creation of associations of municipalities, here conventionally called areals. This idea develops in the direction of their aggregation, conforming to, and responding to the megatrend of local prosuming. Emphasis is placed on the configuration and role of the areal. Strategic issues that accompany the formation of areals are formulated including models that can become the basis for visioning, strategizing and planning. On this basis, an integral model (vision) for the formation of a specific areal in the Southernmost Danube Arc, called Svibenik (Svishtov - Belene - Nikopol) is launched. The intention is also to combine in one the theory with the design of a real areal structure.
