The Greater Taree council area has suffered an estimated million dollars worth of flood damage over the past two weekends.
Roads and bridges are just starting to emerge from water after the latest flood.
Council spokesman Steven Yam said the approaches to around 20 bridges have been washed away.
He said Natural Disaster funding was made available after the Australia Day event but many rural roads suffered more damage last weekend.
"We hope that declaration would cover the event just gone past because our analysis is that the second weekend actually had a heavier impact on us than the first weekend,' he said.
"The priority for council is actually access for people to get to work, to get to services and do their shopping and schools etc.
"There is still a fair bit of water in the catchment as well."
Mr Yam said the main issues are landslides and bridge approaches.
"A lot of our approaches to bridges have been affected or washed out," he said.
"We're looking at about 20 odd bridges.
"When the creeks come down in full force they hit the bridge and they've got nowhere else to go they also hit the sides and both sides of bridges have disappeared.
"We're also looking at a lot of washouts on our roads.
" We've had two flood events in two weekends so we're looking at probably around one million dollars roughly, to clean up."
