Jay Whitby, whose house was also flooded, said she and her neighbours noticed the stream flooding several times over the past few months.
She said the fire service arrived and the community helped by building a dam, adding: “If it wasn’t for all of them I don’t know what we would have done.”
NWFRS group manager Tim Owen said 11 properties were affected and fire crews were pumping the flood water into the estuary via a flood plain – which they are monitoring to ensure no other properties are hit.
The ground maintenance company for the estate, Greenbelt, says the area which caused the flooding is not in their area of responsibility, and that it has dealt with maintenance issues in the past two months where the water runs in its area.
The developer of the estate Anwyl homes, has been contacted for comment.
