subject, and an adequate valuation support is requested to prove its importance, spread the culture of protection and prevention, and sustain policies. The devastating effects of the 2009 earthquake in Abruzzo, the costs and the administrative difficulties originated by it, and the perspective of structural modifications of the territory, have increased the sensitivity about the seismic prevention, and the national legislation (art. 11 of the law 77-2009) converting the Abruzzo law decree establishes the financing of the interventions aimed at preventing the seismic risk throughout the national territory as well, allocating in seven years nearly one billion Euro. The particular combination of economic and ethical aspects fully involves the valuation discipline, especially relating to the planning issues prevention refers to for the evaluation of the concerning investments and their coordination according to the principles of collective interest and the maximum effectiveness and efficiency required by a prevention plan. The essay focuses on an experience in the municipality of Faenza (RA), involved by the “Dipartimento della Protezione Civile” (Civil Protection Department) and by the “Regione Emilia Romagna” (Emilia Romagna’s Regional Government) in the experimentation of the Limit Condition for Emergency (CLE) together with the municipalities of the surrounding territory: Brisighella, Casola Valsenio, Castel Bolognese, Riolo Terme, Solarolo. CLE is the condition allowing the urban area to continue to carry out its main functions after the seism, preserving accessibility and the connection with the territorial system. Referring to a significant sample of buildings in the historic centre of Faenza, the study intends to systematize and include in an unitary model of analysis, valuation and project, two distinct but not distant operative levels: on the one hand, at the level of the analytic foundation of the arguments, the constructive aspects of buildings; on the other hand, at the level of the formation of the project syntheses, the urban planning-administrative aspects concerning the CLE creation. The following phases are envisaged: 1. description of the different architectural units; 2. calculation of the class of capsizing and collapse risk; 3. assignment of the intervention category; 4. calculation of the cost of the intervention works; 5. calculation of revenue in terms of differential of real estate value; 6. proposal of incentive model; 7. individuation of the strategic variables through the analyses of sensitivity; choice of the best CLE arrangement alternative.
