8B.1.1 Objective - Avoidance of Coastal Erosion and Inundation Hazards
The potential adverse effects of coastal erosion and inundation of land, buildings and structures is avoided.
8B.1.1.1 Policy - Effect of Climate Change
By ensuring that subdivision, use and development has regard to any actual or potential effect of climate change on the occurrence or severity of natural hazards.
8B.1.1.2 Policy - Dune Protection
By maintaining and enhancing the ability of active dune areas to provide natural protection against coastal erosion and inundation.
8B.1.1.3 Policy - Managing Erosion and Inundation Hazards
- Existing Buildings and Activities:
By using relocation and avoiding further development and/or retreat of lawfully established existing buildings and activities within the CHEPA.
- New Subdivision or Use:
By avoiding the effects of new subdivision or use on the active foredune areas in managing coastal erosion and inundation hazards.
8B.1.1.4 Policy - Building in the Coastal Hazard Erosion Plan Area (CHEPA)
By ensuring that activities within the Coastal Hazard Erosion Plan Area shall be able to be practicably moved or relocated to an alternative building site beyond the Coastal Hazard Erosion Plan Area, and the foredune reinstated to maintain or enhance its natural buffering ability when that activity is exposed to risk from coastal erosion and inundation (including the foundation structures).
8B.1.1.5 Policy - Current Erosion Risk Zone (CERZ)
By prohibiting use and development of sites within the Current Erosion Risk Zone, unless the activity maintains or enhances the natural buffering effect of the foredune and presents a less than minor risk of increasing coastal erosion and inundation.
8B.1.1.6 Policy - 50-Year and 100-Year Erosion Risk Zones (ERZ)
By providing for subdivision, use and development of sites within the 50-year and 100-year Erosion Risk Zones in limited and managed circumstances, while maintaining and enhancing the natural buffering ability of the foredune area.
8B.1.1.7 Policy - Retention of Volume of Sand Within the Coastal Hazard Erosion Plan Area (CHEPA)
By ensuring that subdivision, use and development of sites within the Coastal Hazard Erosion Plan Area retain the volume of sand excavated from sites within the Coastal Hazard Erosion Plan Area.
8B.1.1.8 Policy - Review: Development and Use
By ensuring the location of buildings, structures and activities within the Coastal Hazard Erosion Plan Area are reviewed when the crest of the foredune, or the top of any dune scarp, recedes to a point within 10 metres or less to the nearest part of a building or activity to assess the risk from erosion and inundation. Buildings, structures and activities may be required to be practicably moved or relocated to an alternative building site as a consequence of the review.
8B.1.1.9 Policy - Subdivision
- Current Erosion Risk Zone:
- By prohibiting subdivision on land wholly located within the Current Erosion Risk Zone;
- By enabling subdivision to be undertaken on land partially located within the Current Erosion Risk Zone, where any new allotment created complies with 8B.1.1.9 b) - Policy – Subdivision;
- 50-Year and 100-Year Erosion Risk Zones
By ensuring that only those allotments proposed to be created with an alternative building site, provided contiguous with and clear of the Coastal Hazard Erosion Plan Area, shall be approved.
8B.1.1.10 Policy - Roads and Parking and Manoeuvring Areas
- By enabling the maintenance and upgrading of existing roads, parking and manoeuvring areas located within the Coastal Hazard Erosion Plan Area at the completion of any beach or dune reinstatement. Any maintenance and/or upgrading shall have the least impact possible on the dune system and enhance the buffering abilities of the foredune where appropriate;
- By enabling hard protection works to be constructed to maintain the lifeline function of the existing transport network.
8B.1.1.11 Policy - Utilities, Works, Services
By enabling the maintenance of existing network utilities, including stormwater discharge structures located within the Coastal Hazard Erosion Plan Area, where beach or dune reinstatement is undertaken at the completion of such works. Maintenance work of stormwater discharge structures should include remediation and mitigation works to reduce the discharge’s impact on the dune system and, wherever possible, enhance the natural buffering ability of the foredune.
8B.1.1.12 Policy - Open Space
By requiring works undertaken on Open Space Zones to enhance the natural buffering abilities of the dune system and, wherever possible, the natural character of that environment.
8B.1.1.13 Policy - Coastal Protection Plan Area
By avoiding the effects of inappropriate subdivision, use, development in the Coastal Protection Plan Area to:
- Protect the natural coastal dune system from inappropriate modification and use;
- Retain the Coastal Protection Plan Area in an undeveloped state, while providing for a limited range of managed access opportunities through the coastal protection plan area, ensuring that:
- The natural shape of the foredune is retained;
- Areas disturbed by any activity are re-vegetated with native dune species;
- Any walkway, cycleway, boardwalk or signage is able to be relocated (or easily removed);
- Any walkway, cycleway, boardwalk or signage is constructed from timber, or similar lightweight material approved and certified by a coastal processes engineer as being appropriate in the Coastal Protection Plan Area;
- No activity results in an increased risk to the environment, people, property or structures from coastal erosion and inundation;
- Ensure the effects of coastal erosion and inundation hazards on built development are avoided.
