Despite recent media revelations that one in eight city home owners now have one or more of the above notations added to their Certificate 149 on council files - which technically means it is land which could require any new dwelling to be raised by more than two metres - there's no need to panic, council's Manager Integrated Planning, Sharon Pope, told the Lakes Mail this week.

Owners fear that any one of these notations could have a negative impact on the value of their property, especially waterfront property on the edge of the lake.

"The inference of the media reports is that land with one or more of these notations on the Certificate 149 is predicted to be flooded by rising sea levels, and that isn't what it means at all," Ms Pope said.

"All it actually means is that land identified in this way is subject to the government and council's relevant flood policy, the flood management manual, as far as development is concerned. These are not new notations we've just added to the records. The notations were approved and applied as long ago as 2008," she said.

"These notations do not mean council is predicting the subject land will be flooded or will be inundated by a rise in sea level or that development isn't allowed because of it. It means that these issues must be taken into account when any development on the property is proposed.

"Owners on the eastern side of the lake in places like Marks Point tend to be on very low, flat land which is almost at sea level and the policy requires a minimum dwelling clearance of 1.8m plus an optional freeboard clearance of 500mm where applicable above sea level, but even then there are options open to owners.

"On the western side of the lake, most of the affected land is at least a metre above sea level and much of that identified land has areas on it which are higher than two metres.

"If a dwelling is proposed on the higher ground, the DA isn't really affected by the policy at all, even if the land has been identified as low laying or subject to flood," Ms Pope said.
