The Assessment of the Public and Private Conveniences in the Urban Transformation Interventions: An Optimization Model for the Value Recapture Adoption
Authors: , , ,
Abstract: In the field of urban transformation interventions, the “privatization” of the potential indirect benefits is a crucial issue. In fact, if not adequately recaptured and managed they can favor the private developers or owners by reducing the share of acquirable public resources intended for the realization of new infrastructures and services. For this reason, the Extraordinary Urbanization Contribution (EUC) was introduced in Italy in 2014 with Art. 16, co.4 of DPR n. 380/2001 to allow an equitable redistribution - between the public and private subjects involved - of the surplus value generated by urban variant interventions. The lack of univocal guidance for determining this contribution has made its application difficult, therefore the work aims to provide a rational and methodological rigorous decision support model intended for the public administration for assessing the surplus value generated by complex urban variant intervention. Its methodological structure is based on goal programming optimization principles. In particular, the innovative contribution of the model is to provide the assessment of the surplus value of “complex” urban variant interventions, or those for which the inclusion of the “time” factor could affect the results and the conveniences of the parties involved. For these reasons, different discount rate values are assumed. The main findings regard the possibility of being used for supporting the public administrations in the correct application of the national regulations, also consistent with the value recapture and value sharing research streams, and for identifying the extra-profit margins and conveniences of the private subject involved.
