Their fears were justified when the tall tree came down in strong winds last week.
Resident Joan Leitch-Keating had a feeling that the tree would fall on her house just moments before it came crashing down on her bedroom roof.
Ms Leitch-Keating said she was in her front bedroom about 10pm on July 16. She heard the winds, which reached up to 80km/h, and considered sleeping somewhere else. After reassuring herself the tree would be OK, she was startled by a crack, which sounded like thunder.
‘The whole house shook,’ she said. A branch struck her roof just metres from where she had been sitting.
‘I was expecting it to come down one day,’ she said. ‘There was tree rot and all the tap root was rotted.’
Neighbour Dolcie Butler said she was ‘always frightened’ the tree would come down.
Her husband complained to Mandurah City Council about four years ago. She said a tree doctor came out and assessed that there was nothing wrong with the tree.
‘It worried me though,’ Mrs Butler said.
Resident Steve Rowsell had also written to council a few years ago about his concerns.
‘But I was told an arborist came out and said the tree was OK,’ he said.
A City of Mandurah spokeswoman said the tree had looked healthy. She said dead limbs had been removed in the past and pruning undertaken to keep branches clear of the road and houses.
