Heathrow is to commence the preparation of a planning application to expand the airport with a new runway.
The application is intended to be formally submitted in 2019, after the government has designated the National Policy Statement.
The news follows the government’s announcement in October that a new runway at Heathrow is its preferred option for airport expansion.
To inform its planning application, Heathrow will undertake extensive engagement and consultation with local communities and other stakeholders on various aspects of the scheme including environmental impacts and project design.
The first step will be to commence wildlife and other environmental surveys in the local area, starting in early 2017.
The latest Community Bulletin from Heathrow, delivered to over 4,000 homes this week, sets out information about this to residents living nearby.
Emma Gilthorpe, Heathrow expansion director, said: “Heathrow has its team in place, working to deliver the benefits of expansion in the most sustainable way.
“During the detailed planning process there will be lots of opportunities for local communities, industry partners and other interested parties to help shape our proposals.
“Together, we want to create a plan that not only boosts the economy - locally and across the UK - but one that delivers a lasting legacy in the local area and tackles important local issues including reducing noise and meeting air quality requirements.”
