Central Coast Council, north of Sydney, was announced post the merger of Gosford City and Wyong Shire Councils on 12 May 2016.

As a potential regional city it comprises an area of 1,681 square kilometres, encompasses 152 suburbs with a total population of over 330,000 people.

Gosford has many types of waterways and water bodies ranging from lagoons, creeks, rivers, dams, overland flow paths, tributaries and estuaries. Floodplain Risk Management Planning can be found here

Flooding in Wyong Shire occurs for a number of reasons- River or creek banks are overtopped. Lake levels rise and cover foreshore areas. Stormwater drainage is unable to cope cope leading to "overland flows" running down a street or through backyards.

You may experience little warning of flooding.

Severe thunderstorms can cause localised flooding of stormwater and some creek areas within less than an hour.

Prolonged periods of intense rain may cause flooding of large rivers and creeks throughout the Shire while flooding of the lakes often occurs after two or three consecutive days of heavy rain.

Floodplain Risk Management Plans are available here
