    - - 527 hectares of new green space and parks
      - 50km of shared-use paths
  - - - Population growth - Atlanta is the largest city in South East USA with 5.1 million people in 2006 up from 1.4 million in 1970
      - Traffic congestion - There are 50 000 km of roads in Atlanta, 90% of residents drive to work everyday experiencing 68 hours of delay per year.
      - Cultural loss - Civil war battlefields surrounding Atlanta, such as Kennesaw Mountain national Battlefield to the north, are under threat from suburban homes.
      - Socio-economic division - Most sprawl is to the north where most white middle-class suburbs have developed. The inner city has had less investment; this is where poor black population has stayed.
      - Water quality and quantity - suburbs along the chattahoochee river increase run-off and contaminate drinking water with pollutants. Over 1 million Atlantans use septic tanks, which often leak. Increased water demand for industry and irrigation uses supplies, affecting fishing habits.
    - - Environmental
        
        Impermeable surfaces - more concrete and asphalt replacing solid and trees means surface water can not enter drainaway, causing flash floods and water contamination.
        
        Agricultural land - Expansion has meant that farmland has been bought and covered with shopping malls and other developments.
        
        Air quality - traffic congestion causes increases in respiratory illness such as emphysema, bronchitis and asthma. Air stagnates here so fumes from vehicles are rarely blown away.
        
        Loss of green space/ecosystems - between 1982 and 2002 over 38% of green space within Atlanta city boundary was built on. The city loses an average of 125 hectares of trees per day by deforestation. Ecosystems suffers as wildlife dies or migrates away.
        
        Hotlanta - the removal of trees such as maple, oak and elm and the addition of concrete encourages more heat build up and a ‘heat-island’ over the city. Temperatures can be more than 10OC higher than the countryside.
