Residents living in the coastal areas of Norfolk are to have their say on the future use of flood sirens.
Residents can be warned of floods by phone, fax or e-mail
The review will examine whether thev should be retained or decommissioned.
In recent years the sirens have been superceded to some extent by the use of alerts on television, local radio, e-mail, text and phone messages.
The review involves North Norfolk Council, the Borough of King's Lynn, West Norfolk, Great Yarmouth Borough Council and Norfolk County Council.
North Norfolk Council has distributed questionnaires to residents asking for comments to be included within the overall review.
A report covering the future of flood sirens along the whole of the Norfolk coast will be presented to the Fire and Community Protection Panel of Norfolk County Council in March.
