A Lake Macquarie councillor hopes making an internal briefing memo public will allay some community concern regarding flood warnings and predicated sea level rise.
Council was last night given the memo after councillor Jason Pauling called for more information regarding the organisation's flood planning process.
Angry Marks Point residents are calling for the current flood mapping to be immediately withdrawn.
Councillor Pauling says residents are worried the projected sea level rise information is misleading and inaccurate.
"There's a large number of properties affected currently and there's a large degree of concern within the community, and a degree of uncertainty across the board," he said.
"So, clearly residents are worried and looking for answers, and looking for what opportunities there are in the future, but, equally to look after their situation now."
But Councillor Brian Adamthwaite says the public deserves to know about anticipated sea level rise and potential flooding issues.
"As far as property values (are concerned), I mean statistical research will show that average mean prices (in affected areas) haven't gone down, and demand for those properties hasn't decreased at all either," he said.
"Unfortunately there's always a lot of misinformation and hopefully the council, and the briefing that's been provided, will help allay some of the fears from that misinformation."
