Diretrizes técnicas e legais para locação de limites edificados em praias

Abstract

The guidelines for leasing built limits built in beaches borders are important in projects of urban intervention, once, the contention wall has a fundamental role as a limit for urbanization. Contention walls also have the function of to minimizing the effects of erosion and flood in urban areas and to do the support of the necessary embankment for the consolidation of the road system. Drawing from a case study of Praia do Amor (Outeiro, Pará, Brazil), where a design project was completed in 2005, guidelines for the correct positioning of the contention wall in borders of beaches were suggested: i) when defining the limits for intervention, to clearly establish boundaries through photographic, ordnance and topography surveys; ii) assess social, economic and infrastructure demands for an accurate definition of the kind of work to be conducted; iii) assess a diagnosis of buildings information such as shape, occupation, landscape and tenure conditions; iv) conduct climate, hydrologic and ocean conditions for a survey of beach environmental conditions for predicting future impacts on the structure to be built; v) locate the contention wall leaving 50m from the protected area in order to keep built structures away form corrosion; iv) in cases which the limits are already occupied by buildings without possibilities for rearrangement, assess contention wall in order to support the effects of waves and currents to avoid collapses and human and material losses in the area.
