The Shire of Exmouth says it will cost nearly $5 million to repair damage caused by heavy rainfall and associated flooding in the town late last month.
Council estimates nearly $4 million is required to repair the town's roads and drain infrastructure, many of which are still clogged with debris.
Work to complete a multi-million dollar realignment of streets in the town's centre has been delayed by two months to June.
The extension of a levee wall at the Exmouth Aerodrome is being discussed after the base of the runway washed away.
The shire also expects to spend $500,00 to repair the town's boat ramp.
The Department of Parks and Wildlife is still assessing the damage at the nearby Cape Range National Park.
The WA Government's natural disaster relief fund will cover most of the damage repair costs.
