THE PLANO DETALLADO DE SANTIAGO BY ALEJANDRO BERTRAND (1889-1890)

Abstract

This article presents and analyzes the potential contribution of the new Law of Contributions to Public Space, to the financing and implementation of public spaces. This article simulates the contribution of private intensive residential densification operations in 15 neighborhoods of the Metropolitan Area of Santiago. The Law constitutes a framework for moving towards balanced urban development through payments for impacts proportional to density. However, the results show that the contribution percentage is insufficient to implement the communal and inter-communal investment plans. In turn, their final contribution in land or money transfer responds to location or lot characteristics because tax assessment and the lot area have greater impact than the density of the residential building, on the contribution to public space. It is shown that when calculating the contributions with the occupation density, distortions occur with respect to the density planned by local zoning instruments.
