Doreen and Dr Vas Khandekar have lived with regular flooding around their Braemar Lodge property for 30 years.

Dr Khandekar said he had contacted council on several occasions and no assistance had been given but is hopeful a recent councillor inspection has prompted action.

The first problem the Khandekars face is the water run-off which is directed through a large culvert under the Old Hume Highway and down-stream through a creek which passes through five small pipes to make its way under Braemar Avenue and continue downstream.

Dr Khandekar said the problem was that the volume of water allowed to pass through the large culvert would often not fit through the five smaller pipes, causing the water to accumulate and flood the surrounding area.

The second problem is caused from a non-operational easement between the Khandekar's property and a neighbouring property.

"The water from a neighbouring property is channelled onto ours because the easement is not operational and hasn't been since 1996," Dr Khandekar said.

"All the water has turned our property into a swamp, the ground is always damp and it's gone under our house causing rising damp and erosion."

Previously, council told the Khandekars to be patient, but after 30 years, this was the straw that broke the camel's back.

"In the last downpour of rain, we had two schools of fish in the middle of our backyard," Dr Khandekar said.

"We have spent a fortune on plants, because everything is dying."

However, after all this time, the Khandekars refuse to give up and will continue to fight to protect the historic property, which Dr Khandekar called the "icon of the northern gateway".

"If we don't protect it, it will just go down," he said.

"We are tenacious."

Councillor Larry Whipper has visited the site on several occasions and said the flooding issues "are progressively worse".

"We inspected a number of properties which themselves have become inundated with storm water runoff from catchments above. These properties appear to facilitate the movement from their properties onto properties below. Obviously the lowest property collects it all," Cr Whipper said.

"The current situation reflects a lack of acceptable easements and channels."

Cr Whipper said the obvious short term solution would be to increase the pipes under Braemar Avenue to cope with the vast volumes of water.

Part of the solution could also be to open up easements and drainage lines.

"A further information session is scheduled for early December. At that time I am hoping a full report outlining short, medium and long terms solutions will be put up to council for consideration," Cr Whipper said.
