The London Legacy Development Corporation’s new clout will start in October and its scope will include the Queen Elizabeth Olympic Park, said a spokeswoman.
"The corporation will become the local planning authority for the park and adjoining areas in Tower Hamlets, Waltham Forest, Hackney and Newham.
"The new Planning Policy and Decisions Team will determine planning applications, appeals, enforcement and listed building consents."
Vivienne Ramsey, currently Director of the Olympic Delivery Authority’s planning decisions team will head up the new group and will draw up a local plan for the area and set a charge for the new Community Infrastructure Levy.
"We will working closely with the boroughs of Hackney, Newham, Tower Hamlets and Waltham Forest and the Mayor’s office to develop a planning service that works for all communities," said Ramsey.
The corporation’s interim chief executive Dennis Hone said: "This is the next logical step in ensuring we are able to maximise London’s 2012 legacy through developing the Queen Elizabeth Olympic Park and surrounding areas of east London.
"Being a single point of contact for regeneration – landowner, developer, planning authority and investor – will better enable us to secure and promote high-quality sustainable development and investment in order to benefit local communities."
He said the team would run like any other planning authority. Most of the land had been earmarked for the Queen Elizabeth Olympic Park, to consist of a North Park of wetlands and rambling spaces and a South Park more urban in feel.
Landscaped areas of the park will wrap around five new neighbourhoods of 8,000 homes, schools, health centres and shops. Other sites will be transformed into new business areas.
