Under the influence of society-wide developments there is an immediate need for an imperative solution to the question of broad based integrated planning of territorial development with a synergistic effect. Spatial management creates the foundations for the harmonization and functional use of a territory. Its development is negatively influenced by exceptional events originating on the given territory. The incorporation of preventive measures into strategic documents of spatial management provides an increase in security for the territorial unit. This paper focuses on the assessment of specific preventive measures for the origin and minimization of the consequences of exceptional events. Particular attention is paid to a selected group of exceptional events, namely natural disasters. The aim of the paper is, on the basis of suitably set criteria, to designate measures through the method of multi-criteria decision-making. The purpose of selecting the most suitable measures with the use of the multi-criteria decision-making method is to see them put them into practice and directly incorporated into strategic territorial planning documents.
