  • Timescale of 10 years
slide22

Air Quality

CO Emissions

slide28

Air Quality

NO2 Emissions

main facts
Main Facts
  • NO2 is the only pollutant to be considered
  • Not a major threat over 10 meters
  • Motorway represents the main pollutant source
slide35
EIS

Traffic

Noise Impact

mitigation measures
Mitigation Measures
  • Public-bus network
  • Speed limit
  • No-building area
  • Screens
slide45
EIS

Hydrology

Water Quality & Runoff

runoff
Runoff
  • Baseline runoffs:
  • Igelbäcken 45 l/s
  • Bällstaån 120 l/s
runoff1
Runoff
  • Very small runoff increase
  • Cumulative impacts. Be careful!!!
water quality
Water Quality
  • Less nitrogen released
  • Phosphorus increase in Bällstaån
main facts1
Main Facts
  • Overflow will increase
  • Improved water quality
slide50
EIS

Ecology

Flora, fauna & landscape

slide51

Impacts on Landscape

  • 0 Alternative  Fragmentation
  • Other alternatives  Opens the ”Green wedge”
slide52

Impacts on Flora

Deciduous, coniferous, oak trees, grass

  • Only impact will be on the edge of the forests (ecotones) for alternative 2 and 4
slide53

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
population economic growth
Population & Economic Growth
  • Population base & high level for the municipality (Regional plan)
  • Green buildings concept
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
slide61

Public Participation

  • Interviews & questionnaires
  • Meetings
slide62
EIS

Monitoring

slide64
EIS

Conclusion &

Recommendations

slide65

No big difference between the alternatives for environmental impacts

  • Big differences in social impacts

 We decide to recommend

Alternative 4

slide66

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

  • Avoids uncertainty concerning further development of the IKEA commercial area
slide67

Very good public transport network

  • Limited impact on the environment (no excavation, no deforestation)
  • Improvement of water quality (especially in the Igelbäcken)
