Strategic spatial planning can be defined as a quite diverse planning activity. According to A. Faludi and W. Salet (2000) three approaches can be distinguished today: (1) institutional approach, (2) communicative or ‘discoursive’ approach, and (3) interactive approachto planning. In Slovenia, formalised beginnings can be observed in the 60ties of the previous century. The context of strategic spatial planning has changed substantially with the introduction of explicitconservation requirements. Spatial plans have lost their strategic nature provided by legislation. The reason for the change was the concept of intrinsic values that has been introduced by certain planning actors. Such a concept abolishes the feasibility of a societal discourse and obviousness of reconciliation in order to draw out a strategic spatial plan. Many attempts done in Slovenia since the 70ties in order to use strategic planning in practice have failed.
