Land Development Planning: New Principles and New Representations in the General Urban Plan of Parma

Since the entry of Emilia-Romagna Regional Law No. 24/2017 Disciplina regionale sulla tutela e l’uso del territorio , the processes guiding the development of the territory have profoundly changed, in principle, in the structuring through processes of participation and how contents are expressed and represented. Concepts such as the containment of soil consumption as a non-renewable resource; regeneration of urbanized territories; protection and enhancement of land, including agricultural land; protection and enhancement of historical and cultural elements; and promotion of greater levels of knowledge of the territory and its existing built heritage are the main principles of the law that give foundational importance to the entire process of forming the knowledge framework and strategic lines that structure General Urban Plans, which are designed to express planning contents through an ideogrammatic type of cartography. The analysis of the law and its contents also becomes an opportunity to reflect on the tools through which the governance of the territory is implemented, from GIS to web GIS up to the changes in the graphic language through which the planning principles are expressed, with specific reference to the planning tools of Parma, on which the new General Urban Plan (PUG) is being defined.
