EIS Description of Alternatives

Zero-Alternative
5
The proposed development does not take place The Barkarby Airport remains No -or few- new housing in the area Zero-Alternative
6
Increasing road traffic of approx. 2% per year Increasing noise pollution (plane and road traffic) Increasing air pollution (plane and road traffic)
7
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

19
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
20
EIS Traffic Air Quality
21
Traffic Assumptions Traffic increase 2% per year Timescale of 10 years
22
Air Quality CO Emissions
28
Air Quality NO2 Emissions
34
Main Facts NO2 is the only pollutant to be considered Not a major threat over 10 meters Motorway represents the main pollutant source
35
EIS Traffic Noise Impact

41
Mitigation Measures Public-bus network Speed limit No-building area Screens
45
EIS Hydrology Water Quality & Runoff
46
Runoff Baseline runoffs: Igelbäcken 45 l/s Bällstaån 120 l/s
47
Runoff Very small runoff increase Cumulative impacts. Be careful!!!
48
Water Quality Less nitrogen released Phosphorus increase in Bällstaån
49
Main Facts Overflow will increase Improved water quality
50
EIS Ecology Flora, fauna & landscape
51
Impacts on Landscape 0 Alternative Fragmentation Other alternatives Opens the ”Green wedge”
52
Impacts on Flora Only impact will be on the edge of the forests (ecotones) for alternative 2 and 4 Deciduous, coniferous, oak trees, grass
53
Impacts on Fauna Alternative 4 and 12 are close to the Igelbäcken Impact on fish Mitigation Restricted access to the stream Stone Loach and Spinned Loach
54
EIS Social
56
Population & Economic Growth Population base & high level for the municipality (Regional plan) Green buildings concept
57
"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
62
EIS Monitoring
64
EIS Conclusion & Recommendations
65
No big difference between the alternatives for environmental impacts Big differences in social impacts We decide to recommend Alternative 4
66
Better balance between the needs for housing and the economic development of the area Avoids uncertainty concerning further development of the IKEA commercial area
67
Very good public transport network Limited impact on the environment (no excavation, no deforestation) Improvement of water quality (especially in the Igelbäcken)
