Construction of retaining walls across Wye River and Separation Creek

Colac Otway Shire is currently constructing 21 retaining walls across Wye River and Separation Creek. 

 The new walls will replace retaining walls located within the Council road reserve that were damaged in the bushfire. Council will be using non-combustible materials including steel I-beams and reinforced concrete sleepers for new structures to increase their resilience to future fire events.

Council’s contractor, Leprechaun Landscaping, commenced works in Separation Creek on Monday 19 June 2017. It is likely to take four months to complete all of the retaining walls, subject to weather conditions. All affected property owners will be contacted individually before the commencement of any works. The work is being done in several stages.

As at mid August 2017, stage five construction will begin.

Residents and visitors please note, major delays and road closure will occur on Koonya Avenue, Wye River  – between Durimbil Avenue and Dunoon Road – from Monday 21 August through to Friday 25 August 2017.

Road access will be available to general traffic at approximately 5pm on Friday 18 August.

Access to Dunoon Road will be via Karingal Drive.Construction of Stage 5 retaining walls:

3 Durimbil Ave – 14 to 25 August 2017                  

10 Durimbil Ave – 14 to 25 August 2017                  

16 Durimbil Ave – 14 to 25 August 2017                    


Reticulated drainage for the townships of Wye River and Separation Creek

Colac Otway Shire has contracted Cardno to design the reticulated stormwater drainage system it is installing across the two townships. Cardo is a professional infrastructure and environmental services company, with expertise in the development of physical and social infrastructure for communities around the world.

The concept design for the stormwater reticulation system is complete, and we are keen to hear your feedback on it.

The stormwater concept designs are now available to view here. (PDF, 45MB)

A one-page PDF explaining the designs can be downloaded here(PDF, 98KB)

We are holding two community drop-in sessions for public comment on these designs in Wye River and in Melbourne, before detailed designs are produced in September. All property owners and residents welcome. No need to RSVP, please just come along.

Construction, Traffic and Environment Management Plan

On Wednesday 28 June Council approved the Construction, Traffic and Environment Management Plan (Plan), which was developed by Colac Otway Shire and Coffey to guide construction during the rebuild phase of renewal.

The Plan will provide residents planning to develop or construct residences on their land with guidance on meeting the planning approval requirements of Colac Otway Shire. Many of the management measures provided in this plan are based on Victorian government policy or legislation; others have been introduced by Colac Otway Shire to meet the requirements of the communities of Wye River and Separation Creek. 

Colac Otway Shire, along with all residents and principal contractors will ultimately be responsible for the implementation of the Plan for Wye River and Separation Creek and communication with all relevant stakeholders.

This will involve:

  • Enforcement of compliance with EPA Maximum Construction times to moderate the impact of construction activities on the local community’s amenity
  • Implementation of the temporary traffic management plan and associated parking restrictions to ensure the safe movement of traffic and minimize the risks to vehicle operators and pedestrians. This includes the enforcement of a 20 km/hr speed limit for the area. Enforcement of current legislation and, if required, higher control standards stipulated within the plan to minimize damage to the environment and amenity.

The CTEMP will be administered through the use of planning and building permits within the Wye River and Separation Creek townships. Landowners wishing to rebuild will have to comply with the requirements of the CTEMP and ensure that all contractors also strictly adhere to the plan. These requirements will be issued on all future planning permits for demolition/removal of a building, construction of a new building, or construction of retaining walls over 1m in height.
