No full textControllare l'impossibile. Urbanistica e consumo di suolo nella sfida per la città futura
No full textEuropean policies, aimed at reaching the target of zero land consumption by 2050, call for a reflection on the past experiences of environmental preservation actions carried out in different territorial contexts. Authors’ aim is to point out the limits and the opportunities of different regulatory tools, mainly market-based, founded on the development rights transfer for soil protection. These limits and opportunities are compared to the traditional normative
Non financial compensation for the redevelopment of the historic urban landscape: the case study of Villasor in Sardinia (Italy)
Get PDFIn Europe, the debate on the recovery of the historic centres has been developed, over the years, around the balance between conservation and transformation needs in order to meet the new demands of the contemporary world. In the field of urban planning, the strictly conservative and binding approach has gradually been supported by flexible and consensual mechanisms that act as a stimulus to private initiative in the redevelopment and regeneration of the historic urban landscape. The consolidated Italian experience in the policies for the protection and enhancement of historical settlements is being significantly innovated after the entry into force of the Urbani Code, which extends the character of landscape heritage to the historic urban fabric, transferring to the regional authorities the task of establishing the specific regulations for its use and transformation. The Region of Sardinia has achieved an important role in the implementation of policies for the recovery and redevelopment of the historic centres identified by the Regional Landscape Plan (RLP). The common and consolidated practice is still characterized by the use of traditional regulative instruments, in particular the detailed plan, which provide rules for the requalification of the compromised urban fabrics through a set of rules and guidelines to be applied to the replacement of recent buildings and the renovation of urban patterns that for density, ratios between solids and voids, heights, alignments and elevations are incompatible with the values of the context. The constraint and binding approach is effective in the conservation strategies but often inadequate to implement actions of integrated redevelopment of urban fabric altered by new buildings in contrast with the historic urban landscape features, also due to the global crisis situation and the shortage of public funding. The paper proposes the use of the non-financial compensation tool, based on the granting of bonus development rights to realising on site or in alternative locations, in order to encourage urban regeneration projects that also involve the replacement of buildings incompatible with historical urban landscape morphological patterns. The integration of a methodology for assessing the financial feasibility of the demolition and reconstruction of the incompatible structures in the planning process, as tested in the case study of Villasor municipality, has allowed the elaboration of a model to support the use of a compensation mechanism for the redevelopment of historical settlement values. In this perspective, the paper aims to investigate the opportunities provided by market-oriented and flexible approaches to support and promote private urban regeneration projects. In particular, it illustrates the experimental results of a methodology for the analysis of the urban fabric that takes into account the factors influencing the feasibility of the intervention of demolition and reconstruction of the incompatible buildings. Finally a model for the assessment of any bonus in terms of additional building capacity is suggested, to be granted to private operators as an incentive to ensure the cost-effectiveness of the project
Città pubblica e rigenerazione urbana nei nuovi strumenti di piano. Il caso di Cagliari
No full textIl piano particolareggiato per il recupero del centro storico di Cagliari. Prime considerazioni critiche sulla proposta di piano
No full textThe recent coming into force of the urban renewal plan for the historic
centre of Cagliari is an opportunity to reflect more widely on the urban policy renewal
innovations and, more specifically, on issues related to the effectiveness of
historic centre urban renewal plan implementation. The authors intend to highlight
some important contradictions of the regulatory plan apparatus that should be subject
to structural review. They also suggest possible supplements
La difficile attuazione del piano urbanistico tra regolazione multisettoriale e politiche tradizionali
No full textL’applicazione di meccanismi perequativi e compensativi pensati per intervenire nei tessuti urbani consolidati,
ed in particolare nella città storica, dovrebbe essere anche finalizzata a coinvolgere il privato nella costruzione
e nella manutenzione della città pubblica e ad attivare processi di recupero dal basso.
Nel far fronte all’esigenza di miglioramento della qualità urbana e di sostenibilità ambientale in generale,
occorre fare i conti con gli ingenti costi della riqualificazione e con la scarsa disponibilità di risorse da parte
degli enti locali. Il partenariato pubblico privato costituisce ormai una soluzione “obbligata” per l’attuazione di
piani e progetti urbani. Parallelamente alla necessità di definire una nuova forma per il piano urbanistico è
necessario introdurre, nella pratica urbanistica, innovative modalità di attuazione che consentano di superare le
difficoltà legate all’esproprio e di coinvolgere il privato nella costruzione della città pubblica
Regional Landscape Planning and Local Planning. Insights from the Italian Context
Get PDFLandscape has acquired great importance in the urban and territorial policies of European countries after the European Landscape Convention. Italy has a long tradition in the protection of landscape and cultural heritage, characterised by a particular attention to the history and the identity culture of the communities. The main rule in this field, the Code of Cultural Heritage and Landscape of 2004
(Urbani Code), refers to a mix of environmental, cultural, and social factors belonging to different types of natural and urban landscapes that Regional Landscape Plans have to identify, sharing with local communities. The most important innovation concerns the attempt to overcome the binding and regulatory approach, only focused on protection constraints, in order to generate high awareness about the
identity value of landscape and to encourage a more democratic community participation in the landscape policies. The ineffectiveness of landscape policies is often due to the lack of sharing of the landscape vision and planning approaches established at regional level, with local authorities and settled communities. This paper reflects on the topic of inter-institutional collaboration between national,
regional, and local authorities, by focusing on the process of adaptation of urban local plans to the regional landscape plans and comparing different regional contexts. The article highlights a strong delay in the approval of regional landscape plans and a relevant inter-institutional conflict in the co-planning phase with the national authority, leading to the ineffectiveness of landscape plans in the
transfer of regional landscape planning guidelines to the local landscape scale, with relevant consequences on territorial government, between conservative measures and transformation drivers
The role of regulation in the land-take control. The Italian case of the metropolitan city of Cagliari
No full textUsing natural land for the transformation of settlements into extensive and sprinkled agglomerations is particularly clearly seen in the urban and the metropolitan contexts. The European Union provisions will move the European Countries towards the target of zero land-take by 2050, including regulatory measures and incentives to pursue this goal. This paper proposes to assess the effectiveness of the regulatory approach adopted by Italy for landscape planning. In particular, the Landscape Plan developed by Sardinia Region will be analysed. This one aims at limiting the urban expansion for the construction of new housing units only as a result of actual housing requirements that cannot be met only through the recovery and reuse of areas. Focusing on the case of Cagliari metropolitan city, the study assesses the increase in the urbanised areas as well as the incoherence among the demographic trends – the housing needs and the planning of new residential expansion in the municipal urban plans adapted to the Regional Landscape Plan. The research highlights the ineffectiveness of landscape planning regulation in the reduction of land-take phenomenon and the need for a strategy at the supra-municipal scale to coordinate urban demand planning
