Ipotesi progettuali applicate nella stima di indennità di esproprio

The case-study here proposed concerns the evaluation of indemnity of expropriation of a non-conventional real estate placed in a high value environmental-urban context; the evaluation has been carried out within a Board of Arbitrators. The expropriation of central areas in sensitive contexts exposes urban policies to many problems springing from plurality and instability of their price: plurality due to the complexity of the context and to the possibilities descending from asset’s characterization; instability following the extraordinary possibility of use, and the complementarity with the potential operators. In the estimative process a “plan oriented” approach has been implemented; the options of use and the capacities of improvement have been selected and suggested combining the directions of General Urban Plan with the instructions of the Consolidated Act about the Expropriation. These instructions summarize the difficult and contrasty stratification of the special legislation. Moreover they present explicative gaps and interpretative doubt operating both as limits and as opportunities. A multiform characterization of the asset emerges transcending both the asset’s material characters and the local market scale. The variety of the potential social uses stimulates a different idea of public territorial policy, furthermore it encourages the civil utilization’s adequacy with the improvement’s opportunities. The need to synthesize between urban and landscape values, practical and symbolic functions, social and individual interests, concentration and diffusion of value, local and general targets, material input and cultural output, and then also between improvement of physical asset and continuity of corresponding material and immaterial income, they both need an enlargement of value approach and also in the seemingly peaceable privatistic-legal evaluations.
