It is estimated more than $100,000 damage was caused when a large section of Roses Gap Road was washed away and a gaping hole appeared during last Tuesday morning's downpour.

It is the second time in four years this type of incident has occurred and Northern Grampians Shire Council has moved to ensure it doesn't happen a third.

Council has announced it will apply for funding to repair and restore the road, but also complete mitigation works that reduce the risk of it happening again.

Engineers have estimated the total cost of the project to be around $200,000, a cost Council doesn't want the burden of having to bare all on its own.

"We're making an application of funding to Department of Treasury and Finance through VicRoads as part of the Disaster Recovery arrangements that we have with the State and Federal Governments," Northern Grampians Shire Council chief executive officer Justine Linley said.

"This hasn't been declared a natural disaster area, but clearly there was enough volume of rain for significant damage to occur on that particular piece of road.

"We're hopeful that at least the replacement will be covered, but what we're very conscious of is that we don't want this to happen again.

"It has only been a couple of years and we've ended up with the same stretch of road with almost identical damage because the culvert isn't wide enough."

Ms Linley said the cost of the enhancement which could include an additional road side culvert would be considered by councillors as part of their budget discussions.

"Even if we do a forecast variation, but it would make good long term asset management sense to put a larger culvert in, that means that no one has to cover the cost of this again and it also reduces the risk substantially of it happening again,” she said.

“I can’t guarantee that if we don’t do that mitigation work, than when we get another big rain and we won’t end up with another $120,000 of restoration works.”

Mayor, Cr Murray Emerson along with Council’s Director Infrastructure and Environment Sanjay Manivasagasivam toured the effected area on Monday, taking in the scope of the damage and holding talks with businesses in and around the area to make sure they haven’t been directly effected.

Roses Gap Road has been closed as work to repair it to a point where it can at least be driven on continues.

“It could be that the culvert works happen at a separate time but we’re working really hard to get it up and running as soon as we can,” Ms Linley said.

“It really brings to the fore how important it is that if you’ve got an opportunity to mitigate and change things when you know something is likely to happen again that you actually put those things in place.

“We think that’s sustainable long term and the issue that we’ve got for Roses Gap is that they’ve been hit year after year, it doesn’t matter whether it has been with a flood or fire, or flood again.

“Roses Gap Road is a major access route through to not just Roses Gap but through to the Wartook Valley from this side of the Grampians, it’s a beautiful part of the Grampians and it is one we encourage people to visit.”

VicRoads Acting Regional Director, Chris Dunlop said he is aware Northern Grampians Shire has made an application for funding.

“VicRoads assists local and state governments by providing an assessments role of road rectification claims submitted by local councils as a result of flood damage,” he said.

“VicRoads understands that a claim will be submitted by Northern Grampians Shire Council, which will be assessed on its merits using an established process.

“These findings are then submitted to Department of Treasury and Finance for further action.

“As Roses Gap Road is a council asset, management of the road is the responsibility of local government.”
