Tough proposals in order to reduce the impact of a third runway at Heathrow Airport have been promised by opponents of the expansion.
Members of the public have been invited to a consultation in order to give feedback on the plans.
Heathrow is due to publish its proposals to cover the phases of the construction work, designs of the new facilities, the reconfiguration of the M25 and how airspace will be used by additional flights.
John Stewart, chairman of the group Hacan, which opposes expansion at the airport, said his organisation will be putting together “tough proposals” to mitigate any impacts of a third runway.
The Department for Transport says it is on track to publish final proposals in regard to the expansion in the first half of 2018, which will be subjected to a vote in Parliament.
It is hoped that construction will begin in early 2021.
