Remedial works to the cliffs above Tenby's North Walk are set to start on Monday.
A landslip occurred on the cliffs below The Norton in April last year and, following a review of stability, Pembrokeshire County Council were now proposing further remedial work, members of Tenby Town Council were told on Tuesday night.
The work would include 'soil nailing', vegetation control to to remove bind weed, and litter picking of the slope between W. H. Smith and the Duke of York Walk.
The contract was expected to last four weeks and 'some disruption' of The Norton was likely.
There would be traffic-light control on The Norton and the county council felt that it could be necessary to close the promenade walkway at times.
The county council had stressed to contractors that no work would be permitted over Easter, including the siting of any temporary contractors' stores or site accommodation.
A grant had also been awarded to the county council by the National Assembly allowing them to carry out further appraisal and remedial works over a wider area of the North Cliffs following the various rockfalls and landslips during storms two years ago.
The first stage of this work would be detailed inspections of the cliffs between Easter and the Jubilee holiday. Any slope stabilisation work would then be carried out in the autumn and winter.
Clr. Mrs. Maureen Ward felt that the news was 'wonderful', while Clr. Mickey Folland 'fully supported' the action being taken.
"However," he added, "there are naturally occurring springs serving wells under the Royal Lion and Royal Gate House hotels.
"Perhaps we should warn the engineers just in case they are not aware of them."
