Flood Planning

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

The primary objective of the Government’s Flood Policy is to reduce the impact 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.

Note: The NSW Floodplain Development Manual 2005 defines a flood planning area as the area of land below the flood planning level and thus subject to flood related development controls. 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.

Council uses three main tools to manage development in flood planning areas. The Local Environment Plan, Development Control Plans and Floodplain Management Plans.

The Byron Shire has four major floodplains. To find flood information in each floodplain follow the links below.

If you need Council to provide you with flooding information for your property, you can lodge a Flood Planning Certificate application form with the relevant fee, currently $155/property. Council will interrogate the relevant flood model, using its software and provide a flood certificate, which will generally include the following information:

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

Council does not currently have any adopted flood studies or management plans for the areas of the Shire outside of the above 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.
