The City of Kalgoorlie-Boulder has commenced works to widen the Gribble Creek floodway between Hannan Street and Speculation Drive as part of its ongoing work to address drainage issues across the City.
City of Kalgoorlie-Boulder CEO John Walker said the City had commenced work on broadening the Gribble Creek catchment through Centennial Park as an action from the Council endorsed 2015 Gribble Creek Flood Study.
“Part of the recommendations of the Gribble Creek Flood Study was the widening of Gribble Creek through this area to gently channel the water to prevent flooding up and down stream,” he said.
“To achieve this, we needed to remove between 70 and 80 self-propagated river gums, which are notorious branch droppers, and non-native peppercorn trees in an area about 540 metres long. The trees were removed because once their roots were exposed by flooding and water erosion, they become less stable and are a significant safety risk to the community.
“We appreciate that it looks quite severe to see all these trees knocked over, and we want to apologise to the community for not giving them advance warning that these works were going ahead.
“We’re really looking at a big picture plan here, as we work to address flooding issues, working through the Gribble Creek Flood Study, and in the Charles Street and Hawkins Street areas.”
Mr Walker said that community members concerned by the tree removal had an opportunity to get involved in replacing them at the annual KBULG Community Tree Planting Day on 28 July.
“This year’s Community Tree Planting Day will be held in Centennial Park, and about 2000 plants, including trees, shrubs and low lying ground covers will be planted to help remediate the area and reduce erosion,” he said.
“Our crews will also be planting approximately 1000 street trees in the 2019/20 financial year.”
