The unplanned occupation of the Coastal Zone has promoted the replacement of the original natural environment by the anthropic environment. This transformation generates conditions that unbalance the Environmental Diversity (abiotic and biotic natures) and prejudice the anthropic environment. This problem tends to continue and worsen in small municipalities; as is the case of municipality of Jaguaruna, Santa Catarina, Brazil. The present paper presents the method of structuring the first steps of a coastal strategic plan developed in Camacho Balneary/Jaguaruna through actions and scenarios of management based on conflict conditions mapping, the application of the Legal - Environmental Criticality Index (ICLA, in Portuguese), the paradigm of Geodiversity and the local sedimentary dynamics. In a Geographic Information System environment, the regionalization of the Environmental Diversity landscape was carried out by “map algebra” of abiotic and biotic information. After identifying and ranking the main conflict conditions by applying the ICLA, each conflict condition with an area over 1,000 m2 was evaluated. There were 71 conflict conditions, which cover 79.91% of the areas occupied with urban or agricultural activities. When comparing the results with the current management instruments, the main restrictions observed were: disrespect for legal and environmental constraints of occupation; poor sanitation; territory and urban zoning incoherent with the socio-spatial dynamics of Jaguaruna; lack of financial investment; and insufficient technical staff. The management scenarios allowed the design of three different types of intervention (medium term), which reflect different development proposals, for deliberation and implementation by public managers. The methodological proposal, combined with the incorporation of pre-existing management initiatives and plans, provided: the identification and hierarchy of conflict conditions in a simple and intelligible way; the proposition of objective management actions; the spatialization of trend scenarios and the continuity of pre-existing management initiatives.
