Stormwater management helps future-proof against flooding

A comprehensive review of flood preparedness and updated stormwater modelling by the City of Salisbury has confirmed that the actions being rolled out across the City safeguard the local community against a one in 100 year major flooding event.

City of Salisbury has already committed more than $8 million as part of its efforts to manage flooding, with an additional $13 million earmarked for further stormwater management works over the next decade. 

Mayor Gillian Aldridge said the flood management works are tangible actions the City of Salisbury is taking to address and adapt to climate change.

“This approach reflects a great deal of hard work, but updated modelling obtained as part of the review process has helped us to focus our efforts on locations where actions may still need to be considered to best protect people and their properties from floodwaters caused by a major weather event,” Mayor Aldridge said.

“As well as rolling out new drainage systems, we also utilise a number of successful local floodwater mitigation strategies,” she said. “Such as responding to increased stormwater inflows caused by major housing developments by purchasing flood-prone sections of land and in turn, where possible, using them for flood storage, together with the construction of wetlands to flood control dams, and riverbank landscaping to protect areas up and down stream of these sites.”

“Because the City of Salisbury doesn’t operate in isolation, we also monitor and address additional stormwater inflows that are likely to impact on our catchment areas from significant housing developments in adjacent council areas.”

Mayor Aldridge said the Council is now using the updated flood modelling to identify and in turn contact residents and businesses identified as potentially being impacted by a significant weather event and invite them to a drop-in information session to speak directly with Council staff. 

“These information sessions, combined with our normal contact channels, offer an opportunity for us to better understand community expectations about flood risks and address any concerns that our community might have,” she said.
