"8D.1  Objectives and Policies for Areas Subject to Flooding from Intense Rainfall"

Updated 16 November 2020

Proposed Amendment

"8D.1.1 Objective - Avoidance or mitigation of flooding from intense rainfall"

"The flood risk to life, property and infrastructure resulting from subdivision, use and development of land is reduced over time taking into account the effects of climate change."

"8D.1.1.1 Policy – Floodplains - General"

"Maintain the conveyance function and storage capacity of floodplains by:

  1. Restricting the infilling of floodplains;
  2. Restricting activities within the floodplain; and
  3. Restricting urban development and subdivision within the floodplain."

"8D.1.1.2 Policy - Overland Flowpaths - General"

"Maintain the function of overland flowpaths to safely convey flood water and reduce risk to life, property and infrastructure by:

  1. Maintaining the water carrying capacity of an overland flowpath;
  2. Maintaining the water storage capacity of a major overland flowpath;
  3. Restricting activities that may obstruct an overland flowpath;
  4. Ensuring that the risk of flooding is not transferred to other people, property or infrastructure; and
  5. Ensuring that the minimum freeboard level of habitable rooms is 500mm above the flood level; and
  6. Demonstrating that safe evacuation during flood events is provided."

"8D.1.1.3 Policy - Floodplains and Overland Flowpaths - Critical Buildings and Social and Cultural buildings"

"Manage activities to reduce the risk to life and property from flooding including:

  1. Avoiding new critical buildings being located within floodplains and overland flowpaths
  2. Avoiding new social and cultural buildings being located within floodplains and overland flowpaths; and
  3. Restricting additions to existing buildings located within floodplains and overland flowpaths."

"8D.1.1.4 Policy - Flood Prone Area - General"

Requiring new buildings and additions to existing buildings (other than social and cultural buildings and critical buildings) within the flood prone area to mitigate risks from flood hazards by:

  1. Requiring that the minimum freeboard level of habitable rooms is 500mm above the flood level
  2. Ensuring that the risk of flooding is not transferred to other people, property or infrastructure; and
  3. Ensuring that business and industrial activities are designed to minimise damage to goods and internal fittings caused by flooding.

"8D.1.1.5 Policy - Flood Prone Area - Social and Cultural Buildings and Critical Buildings"

"Manage activities to reduce the risk of flooding in flood prone areas by:

  1. Requiring new social and cultural buildings and critical buildings to be located outside flood prone areas; and
  2. Requiring the additions or alterations to existing social and cultural building and critical buildings located within flood prone areas to mitigate risks from flood hazard by:
    1. Ensuring that the minimum freeboard level of habitable rooms is 500mm above the flood level; and
    2. Ensuring that the risk of flooding is not transferred to other people, property or infrastructure; and
    3. Demonstrate that safe evacuation during flood events is provided; and
    4. Ensuring buildings are designed to minimise damage caused by flooding; and
    5. For critical buildings located within a flood prone area, ensuring that the activity within the critical building continues in its normal function during and after a 1% AEP rainfall event concurrent with a 5% AEP storm-tide event, taking into account the effects of climate change on rainfall and sea level based on the RCP 8.5 median scenario as of the year 2130."

"8D.1.1.6 Policy - Impervious surfaces"

"Restrict on site impervious surfaces to manage the amount of stormwater run-off generated by a development and ensure that adverse effects of flooding are avoided or mitigated."
