A DRAFT study on public exhibition until this Saturday suggests continuing with flood awareness programs, optimising flood emergency management, and improving flood warning systems should be high priority actions for the Upper Cockle Creek Floodplain.

Cockle Creek has a 109-square-kilometre catchment area, with six main tributaries, and enters Cockle Bay, on Lake Macquarie, at Speers Point.

Flooding in the catchment has been recorded since the 1930s.

"This risk management study and plan, along with a new, overarching flood study of the area, reassesses design flood levels using latest data and technology," Lake Macquarie City Council environmental systems manager Brad Sutton said.

"It also takes into account predictions of sea level rise."

According to the Floodplain Risk Management Study and Plan, 229 properties in the catchment would be affected by a 'one percent annual exceedance probability flood event'.

This refers to a flood that has a one percent chance of occurring in any given year.

"We are committed to building more flood-resilient communities across Lake Macquarie," Mr Sutton said.

"These plans will help us achieve that goal."

The Upper Cockle Creek Flood Study and Floodplain Risk Management Study and Plan Final Draft Reports are on exhibition until this Saturday, April 13, at shape.lakemac.com.au/upper-cockle-creek-flood-study.
