Isaac Way residents told the Courier they received flyers about planned disruptive earthworks a week before the removal of trees from a block of land behind the Banksia Park Aged Care facility.
Kwinana Mayor Carol Adams said drainage in the area needed upgrading to prevent future flooding of several nearby properties.
Calista resident Isobel, who did not want her surname published, said people living in the area were angry because they had a right to know what would happen to the trees.
‘I had to go to the council to find out what was happening and was told they were extending the stormwater drain,’ she said.
‘By extending the drain, residents will be left with stagnant water odours and an increase in mosquitoes along the street. It’s completely unfair for them to make a decision like this and keep us uninformed.’
Cr Adams said letters were sent to all affected residents, which outlined the general work and contact details for several project officers.
‘The City acknowledges that the notification letter was focused on the works affecting residents’ driveways and could have also described the works planned for the sump,’ she said.
‘The existing sump capacity was not sufficient to contain the flow from the catchment and required expansion to cater for the volume of stormwater run-off from the catchment.’
