The explicit regional planning experiences in Serbia have been elucidated upon the case of the elaboration and implementation approach of the Kolubarski district regional spatial plan. Specific circumstances going along with the plan’s elaboration demanded the advancement of the regional planning methodology with an efficient approach in defining a strong working team organisation, and clear temporal and spatial guidelines. Furthermore, the means were required for the communication improvement between planners and interested groups on the national, regional and particularly local level so as to determine development goals and mediate conflicting interests. In the preparation and consideration of this spatial plan’s elaboration phases, the cooperation between the planners and responsible authorities and expert agencies of the municipalities of Valjevo, Lajkovac, Ljig, Mionica, Osecina and Ub was particularly valuable and useful. The same goes for the Kolubarski district, the Agency for construction and development of the Kolubarski district affected by the earthquake and other expert institutions, organisations and enterprises from this planning region. The achieved cooperation provided for the quality and actuality of the planning propositions and the ensuing approval by the local communities smoothed the Spatial plan’s implementation.
