How many properties are flood affected?
Approximately 410.
What are the flood risks?
- Flooding can occur from flash flooding from the creeks after heavy rainfall in the catchment or from backwater flooding from Narrabeen Lagoon or a combination of both. Flooding in Narrabeen Lagoon can occur after heavy rain in the catchment or from waves and king tides from the ocean during a severe ocean storm or a combination of both.
- Flash flooding means that flooding will occur quickly and there will be little opportunity for warning or assistance before or during a flood. However, flooding from backwater from Narrabeen Lagoon may mean that flood waters could remain elevated for many hours.
What is Council doing?

What can I do?
- Being prepared for a flood is the best way to reduce the risks. The State Emergency Service (SES) is the lead response agency for floods, storms and tsunami across NSW. See the SES website for ways you can prepare for a flood.
- Council will post information on the website and advertise in the local media whenever new information becomes available
