Council play a key role in identifying flood prone land across the Northern Beaches, including the management of risks to life and property from flooding.

In late 2019, we asked you to tell us about your experiences of flooding in the Greendale Creek catchment by filling in a survey and sharing photos and videos.

Thank you to everyone who provided feedback.

From this, we have developed a draft flood study for the Greendale Creek catchment to review and define the existing and future flood behaviour in the catchment and establish how best to manage flood risks into the future.

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.

At the meeting on Tuesday 22 March 2022, Council gave approval to publicly exhibit the draft flood study.

We know our community, particularly in flood prone areas, are busy cleaning up and recovering for the recent storms so we have decided to hold off on starting the formal public exhibition until at least May 2022.

We will have opportunities for the community to discuss the results with us and our engineering consultants at that time.

In the meantime, we will capture on-ground flood information to assist in the consultation process and make any refinements to the final flood study.

View the Council report (Item 11.3) and Attachment Booklet (Item 11.3).

We will send an email and update this page when the exhibition dates are confirmed, noting it will not be any earlier than May.

Project updates

We need the local community to help us better understand flood risks in the Greendale Creek catchment.

Please tell us about your experiences of flooding in the Greendale Creek catchment by filling in the online survey.

Please note that a paper version of the survey is being mailed out to residents in the catchment area, if you prefer to fill it out in writing.

Photos can be attached within the survey and videos can be emailed to floodplain@northernbeaches.nsw.gov.au

Survey closed Sunday 8 September 2019

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.

More information about flood studies is available here.

Council will prepare a Draft Flood Study for Greendale Creek to identify and manage flood risks in the catchment area.
