Northern Beaches Council is responsible for the identification of flood prone land in the Local Government Area (LGA). We also play a key role in the management of risks to life and property from flooding.

One of our most important activities is to increase our community's awareness of flooding so that people are better able to understand and plan for the flood risks they face.

A flood study aims to:

- define existing flood behaviour (including levels and extents)

- help identify flooding problem areas in the catchment

- assess the impacts of climate change.

Council will prepare a Draft Flood Study for Greendale Creek to identify and manage flood risks in the catchment area. The study area comprises all areas that drain to Curl Curl Lagoon, including the suburbs of Curl Curl, North Curl Curl and parts of the suburbs of Brookvale, Narraweena and Freshwater.

The draft Study will be placed on Public Exhibition in early 2020.
