Fini Bologna: Municipal Structural Plan (PSC) > During the lesson "Construction sites and projects“ the focus was on: • the concept of "city" • the "seven cities of Bologna" as a tool to interpret and project the contemporary territory • the different types of projects linked together by each city > In this lesson the main focus is on: • once again on the "cities" as a re-composition tool for Bologna and its metropolitan area • the concept of "infrastructure" considering it in a broader sense • the links between each city and infrastructure > Each city presents and has been built on different structural element Bologna as a “Metropolitan city” and as "City of Cities” are the two images that briefly set out the new approach of the Structural Plan • The main problem is to structure the territory with its archipelago of situations (each of them in some cases functioning as an islands). • In the metropolitan area of Bologna, Seven Cities link together historical nuclei, social housing quarters, citadels, clusters of houses in the foothills. These “chains” of situations are organized by different structural elements, which name the cities as well. • Cities and structural elements: 1. The railway network (the City of Railway) 2. The highway (the City of By-Pass Road) 3. The morphology (the City of Hills) 4. The main river (the City of Reno) 5. A small river and the road which delimitate the east boundaries of Bologna (the City of Savena) 6. The old Roman road towards Piacenza (the City of Western Via Emilia) 7. The old Roman road towards Rimini (the City of Eastern Via Emilia) • The 7 Cities distinguishes new urban forms and chains of spaces in the urban area: they identify differences that are already present and highlight the strategies that will guide future actions. • Each one is strongly linked to the other, but each is unique through their history, characteristics and future strategies, different series of spaces where various populations and social practices prevail, where the way of living changes. The strategic schemes of the Seven Cities of Bologna The City of the Railway – The new image of Bologna The City of the by-pass road: From great barrier to the linking road The City of the hills: A new statute The City of the River Reno: the Construction of a Landscape The City of the River Savena: a Residential and productive city-park The City of the Eastern Via Emilia: another metamorphosis The City of the Western Via Emilia: another metamorphosis The Seven Cities are the strategic and structural image of the new Plan: • Recognize the existence of new types of ‘urbanity’ already present or potential; • Take their name and shape from places, aiming to become familiar to those living there, and to enter the non ‘expert’ public communication circuits; • Identify a clear and strong strategy for each cities: > Strategies can be implemented during a long period of time > through the main transformation projects and through small requalification projects > in the metropolitan districts or neighbourhoods municipalities; • Seek to mobilize thoughts, generate waits, move actions, and motivate care about the territory “…In Bologna, the "seven cities" concept, is the operational tool used to select, to interpret in an unitary way and to link the singular areas of transformation. These areas will transform the physical form and the functioning of the metropolitan territory giving life to other figures of different scales…” "A Bologna le "sette città" sono lo stratagemma operativo per selezionare, interpretare unitariamente e legare insieme singole aree di trasformazione che muteranno l'assetto fisico e il funzionamento del territorio metropolitano dando vita ad altrettante figure quasi sempre di scala sovralocale.“ (P. Gabellini, Fare Urbanistica, Carocci, Roma, 2009, p.65) • So we can consider each city as a "recomposition projects" that gives sense and links different projects of the past (developed in the Previous Plans), of the present and for the future of the city, according with a structural image. • There are present and past projects related to urbanized process and future projects related to future strategy. • Two others important topics… • Two others important topics (I): Structuring cities with Different elements “… Equipment, roads, collective spaces and centralities, ecological networks, water system and sewage networks: for the term 'infrastructure' we must go back to the original meaning, it is what allows and facilitates the continuance of social reproduction, i.e. the pursuit and development of production activities and social practices” “So in this sense the concept of infrastructures is much wider than what is normally understood by the term. The infrastructure of a territory is made up of environment elements as well as roads, communal or provincial technical offices, professional organizations, the hospitals, schools, universities, railway and roads systems…” P. Viganò, B. Secchi (eds., 2001), Territories of a new modernity, Laterza, Roma Bari, pag.118 • Two others important topics (II): Infrastructures in a Wider Sense “… Attrezzature, strade, spazi collettivi e centralità, reti ecologiche, sistemi delle acque e reti fognarie: per infrastruttura si deve tornare ad intendere ciò che consente e facilita la prosecuzione del processo di riproduzione sociale, il proseguimento e lo sviluppo cioè delle attività produttive e delle pratiche sociali” “In questo senso il concetto di infrastruttura è assai più ampio di quanto venga solitamente inteso. Fa parte dell’infrastrutturazione di un territorio l’ambiente, quanto la strada, l’ufficio comunale o della provincia, l’organizzazione professionale quanto il sistema ospedaliero, quello scolastico e universitario, ferroviario o stradale…” P. Viganò, B. Secchi (eds., 2001), Territories of a new modernity, Laterza, Roma Bari, pag.118 • Two others important topics (II): infrastructures in a wider sense • "Giving the right sort of infrastructures means dealing with the question of roads. All the contemporary territories have been increasingly identified as a vast spectrum of times and schedules connected to the still more vast spectrum of the social practices that depend on it“ • "Roads, public transport (railways, trams and buses), bicycle paths allow articulation of movements; build places with different densities and their various accessibilities; direct our attention towards the places of discontinuity where one technique gives way to another; construct new meeting places and services (…). • "Providing new environmental infrastructures means taking a different approach to the one in the past in the construction of a new landscape where contemporary society is represented, in the management of the water supply and system, in the production of energy from renewable sources and its relation to open spaces.“ P. Viganò, B. Secchi (eds., 2001), Territories of a new modernity, Laterza, Roma Bari, pag.120 • Two others important topics (II): infrastructures in a wider sense The city of Railway: the new image of Bologna • It is the city where over the forthcoming years there will be the most important transformations, where there will be a re-composition of the building developments that have grown up both before and after the urban and industrial revolution. • It is the urban figure that stands at the centre of the redevelopment projects that the PSC seeks to oversee, which will provide a new image for Bologna in Italy and in Europe. The City of the by-pass road: From great barrier to the linking road The City of the by-pass road (From great barrier to link road) • These developments suffer all the inconveniences related to the transit and their habitability can only be improved through a system of links and open spaces: - intersections, car parks, cycling and pedestrian ways - areas of mitigation, agricultural spaces on the edges, green connection • The progressive inclusion of the by-pass road, destined to become a metropolitan road, will determine the multiplication of the places directly linked to it: areas of new urban development and places to be re-developed which represent the range of metropolitan uses and practices. The City of the by-pass road: From great barrier to the linking road The City of the by-pass road: From great barrier to the linking road Area Parco Nord: esplorazioni progettuali. Planimetria generale Ipotesi per la riqualificazione della zona a nord della Fiera Coordinamento Prof. C. Quintelli Università degli Studi di Parma – dicembre 2006 The City of the by-pass road: From great barrier to the linking road The City of the River Reno: the Construction of a Landscape The City of the Reno - The construction of a landscape • it is a unifying element in a discontinuous metropolitan city, consisting of urban developments that are mainly residential but not often related to the river park. • this city needs to be recognized as such and to be improved by working on the pedestrian and cycle links across it, on the centrality of the existing districts and on relations with the other Cities. The City of the River Savena: a Residential and productive city-park The City of the Savena – A residential and productive park • For the City of the Savena the emphasis is shifted from the void to the building development of the park, highlighting the difference between the environment of the Savena and that of the Reno, and therefore the differing role that open spaces can play in the two different contexts. • Residential areas, quality manufacturing and services areas are developed together, mixed with open parklands, natural environments, agricultural spaces, composing a (new) real metropolitan city The City of the Western Via Emilia: another metamorphosis The City of the Eastern Via Emilia: another metamorphosis • The two Cities of Via Emilia open the historic center and provide the regeneration of the Roman road on which Bologna was built. This is the condition for reinforcing livability and creating new central points where there are many historical nuclei. Types of interventions: • Introducing a new dedicated public transport systems • Improving of car parks near to the bus stops • Moving of private traffic into existing or new link road • New connections with cycle tracks, linked with basic services and with public bus stops • Improving public areas along the road • Restoring links with neighbouring urban centres The objectives: • to return the Via Emilia to its role as a urban backbone; • to rebuilt transversal links with neighbouring areas that have been interrupted for some time; • to return roads and public squares to pedestrian uses. Differences in the transportation systems and differences in the buildings which have been developed to the east and to the west suggested different planning strategies and designs. • To the east a new automatic trolleybus (Civis) will link the Roman and Medieval city with the eighteenth and nineteenth area of expansion, with the modern Due Madonna and Fossolo districts, and with the new area planned by the PSC in the Savena area. • This succession of interventions will find their common structural point of reference in the redeveloped road Via Emilia. • A metropolitan transport service to the west both above and below ground • It will connect the Roman and medieval city with the first concentrated eighteenth and nineteenth century developments, the old industrial centre of Santa Viola, the old district of Borgo Panigale developed with the creation of the public housing districts of the fifties, sixties and seventies. • Some urban episodes, different and autonomous, which may become a system restructuring the road and introducing a new public transport. 7 Cities: territorial figures: The PSC Strategy 7 Cities: territorial figures: The PSC Strategy Systems and Contexts: For Extending Quality 7 Cities: territorial figures: The PSC Strategy Systems and Contexts: For Extending Quality Situations: For Local Guidelines Bolognina.
