Sustainable urban development vision and projects in Strasbourg

13th October 2011 – Indian official Delegation

I.Local context

andmains development objectives

Strasbourg, the european metropolis

European capitalA transboundary district2d most important Frenchriver-harbour 1st French UniversityA recognized tradition ofinnovation

Key-figures

Area: 316 sq. kmMunicipalities: 28 (= CUS)Inhabitants: 475 000 (CUS)276 000 for Strasbourg -centre city

A metropolitan area, in the middle of the dynamic Upper-Rhine Region

Few keywords

Territory structuring specifities 3 structuring networks : assets for a development project

Nature heritageQuality for urban life.Building landscape identity. Support for biodiversitySupport for local agriculture Organize ecological continuities

Water heritageDensity of water resources and its constraints is a structuring element for conception of the city

Public transport networkConstituting an efficient alternative to the individual car up to the outer limits of the inner-rings suburbs

Strasbourg = dynamic situation, in comparison with others big cities from the North-East of France.

Expected demographic growth within 2030: 50 000 inhab.

This demographic trend has been accompanied by a socio-demographic 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 (1988 - 111ha)

« Frozen » area justifying necessity to enlarge actual city centre.

Socio-economic and other heritages context

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.

Build a city across the Rhine, not only back to the River

II.Implementation of mains

sustainable urban development principles in Strasbourg

Public information, people involvment

Working to build a common cultureExhibitions, publication of guides, conferences cycles, European symposium of ecological districts.

Involve future project’s inhabitantsFrom simple public meetings to regular workshops

Develop specific tools and partnerships

Focusing traditional professional stakeholdersDefine / 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)

3 « actions strategies »

• 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 All urban projects

- urban development- urban renewal

“Transposability” to short / medium term

+

Ecological districts = experimentation laboratories

Spaceconciliate density and life quality Limit urban sprawl

Biodiversity Preserve green « living heritage »

Topics experimented in ecological districts

Mix and diversityPromote a new “living together” model social and intergenerational diversity Prefer district composed of a functional mix instead of “mono-functionnal” district.

Topics experimented in ecological districts

Sustainable mobilityReduce dependence to the car Offer a better and peaceful public spaces quality promote “soft transports” dense urbanisation around public transportation network

Energetic efficiencyReact to the energetic challenge Support inhabitants to the energetic burden (30 % renewable energy)

Resources and wastesLimit ecological footprint Compose with “grey energy concept”

Building methodsPrefer ecological and healthy materials Beyond the price, think to the health

Topics experimented in ecological districts

Participative approachesDo and live together « .... because ecological districts don’t make eco-citizen »

IV.Innovation fields on which

Strasbourg know-how is particularly recognized

1. Local public transport policies2. Ecological districts

3. Co-housing projects

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

Public transportation policies

Implemented in 19946 tramway lines (54 km)58,2 millions (passenger travels) in 2008

Tramway (trolley)

Public transportation policies

Reducing the place of the carPedestrian area (1st French city) Connecting car parks topublic transport network 60 sharing-cars service(23 stations)

Bicycle development plan520 km of cycle tracks1 200 places to park bicycles installed per year8% of urban movements (CUS) - 20% in the city centreCreation of a shared bicycles services in 2010

Modification of the land-use document for reducing car parkingIn a buffer of 500m around tramway network the number of parking place per housing was reduced from 1 to 0,5

6 Ecological districts in Strasbourg / CUS

TanneriesLingolsheim

4/6 of ecological districts will be develop on industrial fallow lands

“Rebuild the city on the city”

650 housings (50 % social, 10 % co-housing) on 7 ha Specificities: exemplary transversal approaches on a specific and efficient part.

Danube: « pilot and flagship » ecological district

La Brasserie / Strasbourg450 housings on 3,8 haSpecifities: industrial fallow lands, no car traffic,

Pilot : Schiltigheim City240 housings on 4.5 haSpecificities : former industrial fallow, rainwater storage system using former industrial bier tanks, and heated by solar installation system

Adelshoffen / Schiltigheim ecological district

« Tanneries » Lingolsheim

Pilot : Lingolsheim City1100 housings on 13 haSpecificities: reconversion of an industrial fallow land.

Pilot : CUS - 1000 housings on 55 ha (25 urbanized)Specificities: nature dimension and place for water deeply included as main component in the projectLocal farming / agriculture also planned

Rives du Borie / Ostwald Ecological district

Kochersberg « Doors » - VendenheimPilot : Vendenheim City350 housings on 8.5 haSpecificities: adaptation of an ecological district model to the 2nd

outer-urban ring : evolution from a residential suburb model to a more dense housing model.

IV.Innovation fields on which

Strasbourg know-how is particularly recognized

1. Local public transport policies2. Ecological districts

3. Co-housing projects

Objectives :

Support emergence and local citizen involvementin the building of them living environment.

Support high quality contemporary architecturein densification of existing urban areas.

Diversify standard models of housing production

Create local reference of performed social and ecological housing

Co-housing pilot project

Definition of co-housing : collective building, bottom-up dynamics

Context in France / Europe

Pioneer policy in Strasbourg: 1st to support directly and actively this approach

Specific actions / projects: dedicating 10 grounds for such projects

Co-housing project: selected projects

Assessment

- Good success of the 1st 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 2nd 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

Co-housing : assessment and perspectives
