Neath Port Talbot Council have now cleared the site of a landslide in Ystalyfera and have started to work to restore the site to how it was before.
A spokesperson for the council said that so far this week they have spent time preparing the site, pulling out tree trunks and clearing the debris.
The landslide in the Swansea Valley happened in December and resulted in 13 families being forced to leave their homes.
