1 Sustainable urban development vision and projects in Strasbourg 13 th October 2011 Indian official Delegation

2 I. Local context and mains development objectives

3 Strasbourg, the european metropolis A metropolitan area, in the middle of the dynamic Upper-Rhine Region Key-figures Area: 316 sq. km Municipalities: 28 (= CUS) Inhabitants: (CUS) for Strasbourg - centre city Few keywords European capital A transboundary district 2 d most important French river-harbour 1 st French University A recognized tradition of innovation

4 Territory structuring specifities 3 structuring networks : assets for a development project Water heritage Density of water resources and its constraints is a structuring element for conception of the city Nature heritage Quality for urban life. Building landscape identity. Support for biodiversity Support for local agriculture Organize ecological continuities Public transport network Constituting an efficient alternative to the individual car up to the outer limits of the innerrings suburbs

5 Socio-economic and other heritages context Strasbourg = dynamic situation, in comparison with others big cities from the North-East of France. Expected demographic growth within 2030: inhab. This demographic trend has been accompanied by a sociodemographic specialisation : the city concentrates younger populations, as well as the most deprived and the richest ones. Stakes : diversification and balance of the housing offer A city focused on creativity and innovation Generalist economy relatively protected due to its diversity, but at the same time,exposed to its dependent relationships to neighbouring economies. A strong tertiary sector, centred on financial activities. Stake : comfort economic balance Historical centre belongs to UNESCO world heritage ( ha) «Frozen» area justifying necessity to enlarge actual city centre.

6 Build a city across the Rhine, not only back to the River 3 axes of strategy Strengthen the metropolitan heartland open to the Rhine : with development of a metropolitan belt including all major international and regional amenities and functions (using opportunities offered by the historical military open landscape around historical centre). Structure secondary district s poles and centres to promote social and functional mix. In fixing intense development here: ensure preservation nature and a high quality of public spaces.

7 II. Implementation of mains sustainable urban development principles in Strasbourg

8 3 «actions strategies» Public information, people involvment Working to build a common culture Exhibitions, publication of guides, conferences cycles, European symposium of ecological districts. Involve future project s inhabitants From simple public meetings to regular workshops Develop specific tools and partnerships Focusing traditional professional stakeholders Define / promote a sustainable urban strategy using a Charta engaging property developer (real estate promoter) to respect more ambitious specifications Experimentation with projects Develop urban projects according to sustainable, development. Like ecological district (i.e: Danube)

9 Ecological districts = experimentation laboratories Regarding to energetic and climatic stakes, we need to redefine the way of building the city Strasbourg = a strong political will to develop ecological districts which aims to become real experimentation laboratories of the sustainable city These experimentations mustn't be reserved for ecological districts but has vocation to be spread to the scale of all the city. Ecological districts could thus be seen as bricks to build a sustainable city. Exemplar experimentation + Transposability to short / medium term All urban projects - urban development - urban renewal

10 Topics experimented in ecological districts Space conciliate density and life quality Limit urban sprawl Biodiversity Preserve green «living heritage»

11 Topics experimented in ecological districts Mix and diversity Promote a new living together model social and intergenerational diversity Prefer district composed of a functional mix instead of mono-functionnal district. Sustainable mobility Reduce dependence to the car Offer a better and peaceful public spaces quality promote soft transports dense urbanisation around public transportation network

12 Topics experimented in ecological districts Energetic efficiency React to the energetic challenge Support inhabitants to the energetic burden (30 % renewable energy) Resources and wastes Limit ecological footprint Compose with grey energy concept Building methods Prefer ecological and healthy materials Beyond the price, think to the health

13 Topics experimented in ecological districts Participative approaches Do and live together «... because ecological districts don t make eco-citizen»

14 III. Main stake areas for urbain development a zoom on the metropolitan heartland

15 Metropolitan heartland: Two-banks projects Train station area Wacken EU institutions A large-scale project 250 hectares 1 million sq. meters to be build housings inhabitants jobs «Two-banks project» Develop the city towards the Rhine Consolidate the European dimension

16 Innovation: Ecocités (Eco-city) project Mobility service pole: Pass mobility Mobility service pole: Pass mobility Transboundary car charge stations Alsace Auto 2.0 Woody demonstrative district Positive energy demonstrative district Smart energy management demonstrative district Entrepot Malraux Collaborative working platform Geothermal heating demonstrative district Medical technology campus Geothermal integrated to basement

20 IV. Innovation fields on which Strasbourg know-how is particularly recognized 1. Local public transport policies 2. Ecological districts 3. Co-housing projects

21 Public transportation policies Public transportation development plan 4 major stakes being coherent with the metropolis development project upgrade quality of the urban public transport network find answers to peri-urban and second outer-ring stakes take up the financing challenge Implemented in 3 key-dimensions check close coherence between urban territorial development and mobility needs and evolution enhance level of performance of public transport services (competitiveness) Financing of infrastructure and of the supply

22 Public transportation policies Tramway (trolley) Implemented in tramway lines (54 km) 58,2 millions (passenger travels) in 2008 Reducing the place of the car Pedestrian area (1 st French city) Connecting car parks to public transport network 60 sharing-cars service (23 stations) s tations voitures adhérents Bicycle development plan 520 km of cycle tracks places to park bicycles installed per year 8% of urban movements (CUS) - 20% in the city centre Creation of a shared bicycles services in

23 Public transportation policies Modification of the land-use document for reducing car parking In a buffer of 500m around tramway network the number of parking place per housing was reduced from 1 to 0,5 Short look about evolution of the way we move in Strasbourg 100% 7% 9% 13% 90% TC 80% 70% 50% 53% 46% VP 60% 50% 40% 30% 20% 10% 0% 2% 8% 33% 1% 6% 31% 1% 8% 33% 2RM vélo marche Dichotomy of urban moves Cars represent less than 50% Strasbourg, 1 st French City (46 %) Walking represents 33 % Bicycle use increase to : 8 % Public transport use inscrease to : 13 %

24 IV. Innovation fields on which Strasbourg know-how is particularly recognized 1. Local public transport policies 2. Ecological districts 3. Co-housing projects

25 6 Ecological districts in Strasbourg / CUS Tanneries Lingolsheim 4/6 of ecological districts will be develop on industrial fallow lands Rebuild the city on the city

26 Danube: «pilot and flagship» ecological district 650 housings (50 % social, 10 % co-housing) on 7 ha Specificities: exemplary transversal approaches on a specific and efficient part. La Brasserie / Strasbourg 450 housings on 3,8 ha Specifities: industrial fallow lands, no car traffic,

27 Adelshoffen / Schiltigheim ecological district Pilot : Schiltigheim City 240 housings on 4.5 ha Specificities : former industrial fallow, rainwater storage system using former industrial bier tanks, and heated by solar installation system «Tanneries» Lingolsheim Pilot : Lingolsheim City 1100 housings on 13 ha Specificities: reconversion of an industrial fallow land.

28 Rives du Borie / Ostwald Ecological district Pilot : CUS housings on 55 ha (25 urbanized) Specificities: nature dimension and place for water deeply included as main component in the project Local farming / agriculture also planned Kochersberg «Doors» - Vendenheim Pilot : Vendenheim City 350 housings on 8.5 ha Specificities: adaptation of an ecological district model to the 2 nd outer-urban ring : evolution from a residential suburb model to a more dense housing model.

29 IV. Innovation fields on which Strasbourg know-how is particularly recognized 1. Local public transport policies 2. Ecological districts 3. Co-housing projects

30 Co-housing pilot project Definition of co-housing : collective building, bottom-up dynamics Context in France / Europe Pioneer policy in Strasbourg: 1 st to support directly and actively this approach Specific actions / projects: dedicating 10 grounds for such projects Objectives : Support emergence and local citizen involvement in the building of them living environment. Support high quality contemporary architecture in densification of existing urban areas. Diversify standard models of housing production Create local reference of performed social and ecological housing

31 Co-housing pilot project Cronenbourg Quartier des Quinze Centre Neudorf Elsau

32 Illustrations : G. Studio architectes Co-housing project: selected projects

33 Co-housing : assessment and perspectives Assessment - Good success of the 1 st consultation: 17 groups - Quality and innovations in projects presented - But necessity to support technically some groups which don t have specialists in their staff Stakes - Develop and democratize more projects - Strengthen methodology to support groups Perspectives - A 2 nd consultation will be initiated (fall 2011) - Grounds for such projects will also be reserved in ecological districts. - Other French cities following this experience (Paris, Lille,...) - Creation of a national network of cooperation piloted by Strasbourg
