Work on a new coastal defence scheme in East Sussex, which could save up to 200 homes from falling into the sea, is due to begin early next year.
The cliff is falling away on land at Fairlight Cove
The houses at Fairlight Cove, near Hastings, are under threat from coastal erosion, with five lost to the sea in the last six years.
Rother District Council approved a planning application earlier this year, but it was blocked by English Nature.
The watchdog raised several objections but an agreement has now been reached.
The scheme has been included in the Department for Environment, Food and Rural Affairs' capital programme, with 100% government grant funding guaranteed.
The council had warned last year that it could not afford the work needed to stabilise the landslip.
Councillor Robin Patten said many of the issues raised by English Nature had been valid, but "the protection of peoples' homes and livelihoods had to take priority over any other matters".
He added that he was extremely pleased that it had now agreed to "a way forward" on the project.
