Japan Street was hit with two major downpours just weeks apart this summer which flooded houses and left a damage bill of more than $1 million at the neighbouring caravan park.

Mayor Vicki Jellie said the council had set aside money to look at the Japan Street stormwater catchment area which had flooded in heavy rainfalls.

The council has budgeted $65,000 this year towards works, and another $580,000 spread over the next two financial years. The council will carry out further assessment works on the stormwater network across the entire city to help it prioritise renewal and upgrade works, it said.

Japan Street flooded twice in January and sparked calls from residents to fast-track and prioritise upgrades to the ageing drainage network.

When the Figtree Caravan Park flooded on January 2, it turned the holiday park into a river of contaminated water and sewerage, leaving a damage and loss of income bill to the tune of about $1 million.

The flooding on January 2 came after a downpour that was described as a once-in-50-year rain event which saw 30mm fall in 12 minutes.

The street was hit again on January 27 when parts of the state received a month's worth of rain in a day.

In the wake of the downpours it was revealed that almost $1 million was needed to solve the long-term drainage problems in Japan Street.

And last year, the council admitted there was already a $1.1 million yearly shortfall in the city's finances to manage the drainage network.
