During heavy rain, the entrance to the culvert that carries Calico Brook beneath the estate became blocked by debris (leaves, branches etc.) and overtopped into the estate, causing extensive flooding to most of the properties. Most residents spent the next few months - up to December '87 - in caravans parked on their front gardens, whilst repairs were carried out. The properties required extensive repair: re-plastering, new woodwork (doors, window frames etc.), with only the higher houses at the entrance to the estate being unaffected.
