Pianificazione urbanistica, paesaggio e valutazione. Una proposta per il Piano Urbanistico Operativo di Cava De' Tirreni

The aim of the paper is to provide a support to evaluation in planning through an application based on the proposal of the Municipal Urban Plan of Cava De’ Tirreni (Province of Salerno, Italy). The goal is to elaborate a Decision Support System to evaluate the landscape and territorial integration of possible alternatives of Operational Plans, which are usually formed after public announcements to select, in a competitive way, the interventions to be implemented in transformation areas. Starting from the concept of landscape areas that divide the municipal territory, the proposed procedure helps the selection of the first Operational Plan, choosing three different urban areas for the experimentation application. The study is articulated in tree steps: 1) check of conformity; 2) economic and financial feasibility, and 3) performance of the plan actions, considering a suitable system of indicators through which verify the goals achievement. The evaluation has been carried out by means of integration between MCDA and GIS, in particular using the ELECTRE multicriteria method.
