Os Planos Diretores de Bacia Hidrográfica e a irradiação de efeitos sobre instrumentos de ordenação territorial

Abstract

This essay reflects the role of Master or Sectorial Plan and their integration. On this way, we present a special reflection on the influence of constant diagnoses in the Watershed Plans, its power to produce urban planning restrictions and also how it reduces the discretion in planning land using cases. This subject has got a lack of reflection in Brazilian legal doctrine, although it's huge empirical relevance. These Watershed Plans' indirect functions, as territorial planning instruments and disaster risks prevention is enhanced due to the recent increase in the occurrence of extreme weather events, especially the urban flood processes. The legal complexity of this subject is boosted by the lack of regulation of the new management system for susceptible areas of disaster risk (called) "natural". Despite the legal uncertainty brought by the lack of regulation, a general duty of mapping and prevention of occupation on areas of risk remains, based more on empirical knowledge of risks (by environmental diagnosis) than in the desirable internalization of restricted measures able to reconcile Urbanistic Master Plans to inserts provisions of Watershed Plans.
