A joint statement by the club and Haringey Council said Spurs are now “seeking to deliver an iconic, new Premier League stadium development and a host of local improvements.”
The commitment follows Haringey Council’s pledge to invest £9m towards new and improved public spaces, heritage work and environmental improvements in North Tottenham.
Mayor of London Boris Johnson has also committed £18m to the regeneration of the area including £8.5m towards a new stadium approach.
Spurs will now push ahead with stadium plans – known as the Northumberland Development Project – costing around £400m.
Tottenham Hotspur Chairman, Daniel Levy, said: “As a major employer and business in the area we are delighted with this commitment from the Mayor and Haringey Council.
“We have long said we could only invest in the area if we could see our commitment supported by others and that there was a real need to maximise the regeneration benefits and lift the wider area.
“We therefore see this as a commitment from the public sector to the Tottenham area and one which strengthens our ability to deliver a new stadium scheme with the potential to kick-start the long-term regeneration of North Tottenham.”
