The growing population of the Tuggerah Lakes' catchment has always lived with the risk of flooding. To help manage the flood situation, Council applies strict development controls for all new housing and infrastructure projects built in low-lying, flood-prone areas. For example, all the latest developments need to have a Minimum Habitable Floor Level of 2.7m above sea level. This means that the new sites must be constructed to this height. Similar building restrictions have been in place for over 40 years.
The Minimum Habitable Floor Level of 2.7m is set 0.5m above the 1-in 100-year flood level, which means that – for safety reasons – it is over 1m higher than the February 2020 peak flood height. It is also the same height as the Probable Maximum Flood in Tuggerah Lakes.
Non-habitable areas within a house such as garages can be built at lower levels. When buying a house in the flood-prone area, it is recommended to check all these necessary safety measures and see whether they comply with Council's regulations.
Managing Flood Risk
To provide our community with the most accurate flood information, Council undertakes several flood studies and develops flood risk management plans for the Central Coast. In these documents, we identify flood-prone areas and investigate how to best prepare for a flood event so that there is minimal damage to the properties and no risk to lives.
If you are a resident of the Central Coast, find out more about your flood risk on Central Coast Council's website.
