Simon Hancox said the Port Macquarie-Hastings Council project to undertake mapping as part of the North Brother Local Catchments Flood Study (2019), could result in negative consequences for residents.

The study outlined areas which are deemed to be flood prone including Bold Street in Laurieton, St Joseph's Primary School Laurieton and Pelican Court, West Haven.

The data for the study has been compiled with some input from residents, sources such as photos and measurements taken during high rainfall events.

Mr Hancox said the flood mapping has been based on a 100-year event, which has not even occurred.

As a result, a major portion of the Camden Haven has been listed as flood prone.

To the best of his knowledge, Mr Hancox said only a small amount of the Camden Haven population has been adversely impacted by flood events.

Mr Hancox is concerned the data collected as part of the flood mapping will be utilised by insurance companies to calculate and determine policies.

Insurance Council of Australia's Policy Risk and Disaster general manager Karl Sullivan said the industry relies on flood mapping conducted by local councils to assess the flood risk at individual addresses.

"A homeowner's insurance premium is based on the risk level of natural hazard exposure at their specific address," he said.

"Almost all local councils around Australia provide the insurance industry with flood mapping, which assists insurers to accurately calculate building and contents premiums.

"If up-to-date flood mapping has not been provided for a LGA with a known flood risk, insurers use a conservative estimate of the flood risk."

The Camden Haven Courier contacted council in relation to Mr Hancox's concerns.

The spokesperson encouraged Mr Hancox and other residents to submit feedback as part of the engagement process, which is open until June 30.

Council's website states the focus of the study is to understand the behaviour of local catchment flash flooding from North Brother Mountain and the flood risk that it poses to the community.
