EIS

Description of Alternatives


Zero-Alternative


Zero-Alternative

  • The proposed development does not take place

  • The Barkarby Airport remains

  • No -or few- new housing in the area


Zero-Alternative

  • Increasing road traffic of approx. 2% per year

  • Increasing noise pollution (plane and road traffic)

  • Increasing air pollution (plane and road traffic)


Zero-Alternative

  • Expansion of the IKEA commercial area in the south

  • Creation of a Natural Reserve around the Igelbäcken

  • Slow restoration of military damaged forests


Alternative 2

The ”Anatomic” development


Alternative 2

  • The ”Anatomic” development

  • The smallest option

  • All around the Barkarby village with a green belt in between


Alternative 2

  • Area concerned: 86.5 hectares

  • 4600 new inhabitants

  • 11 housing areas (9 with apartments – 2 with villas)

  • No public transport network


Description of Alternatives

Alternative 4

The ”American Dream” development


Alternative 4

  • The ”American Dream” development

  • The medium-sized option

  • Mixed use: housing & commercial/business

  • Only on the North of Norrviksvägen


Alternative 4

  • Area concerned: 95.49 hectares

  • 7170 new inhabitants & 3640 work places

  • 6 housing areas (6 with apartments – 2 with villas) & 3 commercial/business areas

  • Bus network, pedestrian and cycling paths in the housing areas


Alternative 12

Description of Alternatives

The ”Tutti Frutti” development


Alternative 12

  • The ”Tutti Frutti” development

  • The biggest option

  • Mixed use: housing & commercial/business

  • Around the village of Barkarby

    (North, East and South)


Alternative 12

  • Area concerned: 133 hectares

  • 11000 new inhabitants

  • 7 housing areas, all with apartments & some commercial areas (undefined)

  • New tunnel under the whole area moving the transiting traffic

  • Bus network, pedestrian and cycling paths


EIS

Traffic

Air Quality


Traffic Assumptions

  • Traffic increase 2% per year

  • Timescale of 10 years


Air Quality

CO Emissions


Air Quality

NO2 Emissions


Main Facts

  • NO2 is the only pollutant to be considered

  • Not a major threat over 10 meters

  • Motorway represents the main pollutant source


EIS

Traffic

Noise Impact


Baseline


0-Alternative


Mitigation Measures

  • Public-bus network

  • Speed limit

  • No-building area

  • Screens


EIS

Hydrology

Water Quality & Runoff


Runoff

  • Baseline runoffs:

  • Igelbäcken 45 l/s

  • Bällstaån 120 l/s


Runoff

  • Very small runoff increase

  • Cumulative impacts. Be careful!!!


Water Quality

  • Less nitrogen released

  • Phosphorus increase in Bällstaån


Main Facts

  • Overflow will increase

  • Improved water quality


EIS

Ecology

Flora, fauna & landscape


Impacts on Landscape

  • 0 Alternative  Fragmentation

  • Other alternatives  Opens the ”Green wedge”


Impacts on Flora

Deciduous, coniferous, oak trees, grass

  • Only impact will be on the edge of the forests (ecotones) for alternative 2 and 4


Impacts on Fauna

Stone Loach and Spinned Loach

  • Alternative 4 and 12 are close to the Igelbäcken  Impact on fish

  • Mitigation  Restricted access to the stream


Social

EIS


Population & Economic Growth

  • Population base & high level for the municipality (Regional plan)

  • Green buildings concept


Green buildings concept

  • "Typical" buildings consume more of our resources than necessary, negatively impact the environment, and generate a large amount of waste.

  • Energy efficiency, use renewable energy

  • Water conservation

  • Waste minimization

  • Reduced operation and maintenance costs


Public Participation

  • Interviews & questionnaires

  • Meetings


EIS

Monitoring


EIS

Conclusion &

Recommendations


  • No big difference between the alternatives for environmental impacts

  • Big differences in social impacts

     We decide to recommend

    Alternative 4


  • Better balance between the needs for housing and the economic development of the area

  • Avoids uncertainty concerning further development of the IKEA commercial area


  • Very good public transport network

  • Limited impact on the environment (no excavation, no deforestation)

  • Improvement of water quality (especially in the Igelbäcken)
