Special Report: Low Density and Costs of Urban DevelopmentBy Hélène Nessi
In Italy, the traditional analysis concerning the use of urban land income is mainly used to explain the urban sprawl and the existing wide under equipped suburb. Such a neo-Marxist approach does not take into account the way soil is allocated and the process set in place to limit such urban rent. What is the best way for society to use such land capital gains as sources for investment in infrastructure network and public equipment? This research attempts to look for a better understanding of the Roman urban development, and to evaluate the efficiency and effects (financial and urban) of the tools set up by the municipality to master or limit urban rent. The analysis based on the study of 4 specific cases show the way infrastructures in network and collective services were financed by the municipality and it shows the capacity for action and the modality it may use for urban planning.
