Meridian Water, a new village on the Lea, moves a step nearer with £170m Housing Infrastructure Fund cash from the government.
The former Stonehill Business Park and bus garage will see 10,000 new homes and shops each side of the navigation linked by new bridges.
The infrastructure grant will enable the construction of the bridges over the Lea and Pymmes Brook to go ahead as well as flood alleviation measures.
The new Meridian Station has already opened in advance of work on the £6bn village project starting next year. Completion is expected by 2040.
Immediately to the south the Lea Valley Walk will pass out of Meridian Water on to rural Tottenham Marsh.
