Flood planning

Flood plan SGB

Council uses three main tools to manage development in flood planning areas.  These are: 

We have four major floodplains:

Flooding information for your property

You can request flooding information for your property from Council if your property is located within a flood study or management plan adopted by Council. Refer to the section below on Flood Planning Requirements for more detail or use the information below to see if Council has flooding information on your property.

Flood information is provided for general purposes only. Council does not prepare the information; it has been supplied to Council by various third-parties at a point in time. Because the information is based on modelling, any particular flood (and the circumstances causing it) may be different to the scenarios modelled by the various studies which provided the basis for the information.

Because of the nature of the information and that it has been supplied, Council does not guarantee the information is free from error or omission. As a result, Council will not be responsible for any damage, however caused, by the provision of the information.

The information is subject to change as a result of updated flood modelling. Council is not responsible for updating the information.

Therefore Council does not warrant that the information is accurate after the day of issue. Council does not know each customer’s reasons for seeking the information. Customers are encouraged to get professional advice specific to their requirements regarding the information.

You can use the following links to determine if flooding information is available for your property before applying for a certificate:

Flood Information Certificate - Online application form

A fee of $155/property applies. 

Council will interrogate the relevant flood model, using modelling software to provide a flood certificate. Certificates will generally include the following information:

Item Maximum Minimum
Ground Levels

Level m AHD

Level m AHD

100 year flood

Level m AHD

Level m AHD

10 year flood

Level m AHD

Level m AHD

100 year Flood Hazard

Flood Hazard (Low/Intermediate/High)

100 year (2100) Flood Hazard

Flood Hazard (Low/Intermediate/High)

2050 Flood Planning Level

Level m AHD

2100 Flood Planning Level

Level m AHD

The above flood information will be sourced from the relevant food study or flood management plan

 

Flood Planning Requirements

Council does not have adopted flood studies or management plans for the areas outside the following floodplains:

Where development is proposed on land that is, or may be considered, within a flood planning area, the applicant will be required to submit a report using local flood information and/or flood modelling to satisfy the requirements of Council’s Local Environmental Plan and Development Control Plan. 

In most instances a professional Civil/Hydraulic Engineer (with qualifications suitable for admission as a corporate Member of Engineers Australia) will be required to prepare this report and/or flood study.

Contact Council’s Development Support Officers on 02 6626 7025 for further information on flood planning requirements.

Managing flood risk

Council manages flood risk in accordance with the NSW Floodplain Development Manual 2005, in consultation with the NSW Office of Environment and Heritage.

The main objective of the State Government’s Flood Policy is to reduce the affect of flooding and flood liability on individual owners and occupiers and to reduce private and public losses resulting from floods. 

The Policy requires that a merit approach be followed when dealing with planning, development and building in a flood planning area.

A flood planning area is the area of land below the flood planning level that is subject to flood-related development controls (from the NSW Floodplain Development Manual 2005). 

The manual defines flood planning levels as the combinations of flood levels (derived from significant historical flood events or floods of specific average recurrence intervals) and freeboards selected for floodplain risk management purposes, as determined in management studies and incorporated in management plans.
