Flood Mitigation Design Projects at Urana and Morundah
Published on 10 January 2024
Federation Council commenced two flood mitigation design projects in June 2023. The projects are being undertaken by consultant’s Dryside Engineering for Federation Council. The projects have now progressed to the completion of the concept design stage. The concept design drawings can be viewed and / or downloaded from this page.
The first project at Urana involves the design of an upgrade of the existing temporary 1.2 km long flood protection levee. The 2.2 km long upgraded levee at Urana will be predominantly located on unused road reserve. The levee will be constructed from a suitable clay based material, topsoiled and grassed.
The Urana levee design crest height will most likely be elevated 0.5 metre above the 1 in 100 year flood level, providing the township with protection from Urangeline and Billabong Creek flooding. Culvert structures will be provided through the levee to cater for local runoff flooding, with provision to prevent backflows from the wet side of the levee.
The second design project at Morundah includes a 660 metres long diversion bund / levee designed to protect the township from local runoff flooding originating from the east side of the town area. The bund will be approximately 0.6 metre high. The bund will deflect local runoff away from the town area.
The Morundah works will also include an upgrade of the gravity pipe drain through the existing creek levee bank adjacent to the stormwater pump outlet facility. The proposed 1.35 metres diameter culvert will provide for extra capacity to discharge local runoff flooding.
The design projects will now progress to detailed design over the next six to nine months. The detailed design drawings will be put out for public comment prior to finalization.
Once the design project are completed, Council will apply in early 2025 for NSW and / or Federal Government funding to construct the flood mitigation works. If Council is successful in accessing funding, the construction works would be expected to take place in 2026.
