In some areas e.g. Spean Street, prior to the flood defence works commencing it is necessary to divert existing pipes and cables. This work will be carried out by the utility companies (BT, Scottish Power, Thus etc) over the next six months.

In most areas the first activity to be carried out is securing the site with new fencing which will be followed by tree felling and site clearance.
