Resumo
For a long time, economic activities occurred in the lack of legal rules. Due to advancement of legislation, many activities became in situation of irregularity, mainly by occupying buildings in protected areas. In this condition, the maintenance or destruction of these buildings should be based on an impact comparative analysis of both alternatives. However, a lack of criteria and standardization of procedures has undermined the proper treatment and decision making. Thus, the purpose of this paper was to introduce a methodological proposal for comparative environmental analysis applied to the settlement of irregular activities. For that, an impact global index was constructed, by means of literature review to identify the parameters involved, as well as to its formulation with use of interaction matrices. The method was applied for assessing an activity that made intervention in permanent preservation area, within consolidated urban area without authorization of competent agency. As a result, an index able to support making decision about maintenance or destruction of irregular buildings was obtained, considering attributes as duration, extension and intensity in the formulation of magnitude of the impact, as well as the parameters of accumulation, reversibility and sensibility to evaluate its importance. Although the proposed method does not eliminate the subjectivity of the environmental assessment, it contributes to standardization through a logical and organized procedure that allows a comparison based on quantitative parameters, especially for smaller projects, usually assessed only according to qualitative attributes.
