This council led project is mapping flooding throughout the Stawell township to identify any options to manage water flows into the future.
The initial stage of the flood study was to collect data which was utilised to inform the hydraulic models. Council received community feedback to confirm the model's accuracy, including:
Photos from the 2011 event
Observations or remarks about the accuracy of the model
Suggestions for flood mitigation for future events
September 2023 – October 2023
Consultation Outcomes
What you said
What we did
Flood shown on property at Short Street unlikely to reach extents shown
Revisited model inputs
Flood water reaches the front fence during large events on Mareli Street
Water flows through backyards between Freeland Avenue and Warren Street
Test to see if enlargement of Grant Street basin would reduce flooding in backyards
Flooding doesn’t reach the shed on Holloway Road East
Incorporated the observation into the model
Clean up area in waterway crossing Ararat Road near Sloane Street
Investigate whether this is feasible
Properties near Franklin Street experience flooding. The drain between Lillian Street and Clifton Avenue requires clearing.
Test to see if enlargement of Clifton Avenue culverts assists in drainage. Assess options for improving drainage infrastructure to reduce flooding.
Flood extents reach low lying parts only of the paddock at the rear of Ormston Road property. No buildings currently sited on this part of the paddock.
Incorporated the observation into the model. Possible future overlays to ensure only appropriate development occurs.
Flooding not experienced at Clifton Avenue
Area around house, road easement and lot at White Street not flooded
Flooding of property occurs near Oregan and William Streets intersection
Test improved pit catchment rates and consider construction of kerb and channel
Floor Level Survey - Underway
Some members of the community will be approached by council to have the floor levels of their homes surveyed. This information is used to identify which dwellings may be at risk of inundation.
Mid 2024
Develop Flood Maps
The design model has been created using the information provided by the community. WaterTechnology has created flood maps which will be uploaded to the council website by 10 June 2024. The community will have the chance to offer feedback for the final report online from 10 June onwards, or to drop into an information booth at the Stawell Library on 13 June.
Test Flood Mitigation Options and Finalise Flood Study
Flood mitigation options will be developed in response to community feedback and a report and flood maps summarising the findings of the study will be provided to the community.
