Project summary

Edit project overview to modify the project summary.


The Olympic Park will bring lasting benefits to east London. After the Games, it will be transformed to include a huge urban park. The new park will link the tidal Thames Estuary to the south and the Hertfordshire countryside to the north.

Some of the major benefits to the environment include:

  • 8kms of river restored
  • 4,000 homes protected from flood
  • 2 million tonnes soil decontaminated
  • The largest urban park created in Europe for over 100 years

Native species planted, including oak, ash, willow, birch, hazel, holly, blackthorn and hawthorn – a home for wildlife in the middle of the city. 30,000 tonnes of silt removed from waterways. 280 hectares of brownfield land cleaned.

750 bat roost and bird boxes put on site.

45 hectares of wildlife habitat created.

20 million gallons of contaminated groundwater treated.

4000 homes in West Ham and Canning Town have reduced flood risk.

99.5 per cent of construction waste re-used, recycled or recovered.

98 per cent of material from demolition work re-used, recycled or recovered.
