Parts of Leyton Marshes were used for the 2012 London Olympic and Paralympic Games, despite some local opposition. A temporary basketball training venue was built on Porter's Field Meadow for the games, which was opposed by members of Save Lea Marshes. The venue was dismantled after the Paralympic Games, the Olympic Delivery Authority being required to return the open space to its original state. In addition, on the request of the local user group, the Lee Valley Regional Park Authority committed to spending £65,000 on improving Leyton Marsh, including pathways and seating, as well as introducing habitats to attract existing and new species of wildlife into the area.
