8.2.8	Landslide Hazard Overlay Code
8.2.8.1	Application
This code applies to assessable development: subject to the Landslide Hazard Overlay shown on the overlay maps contained within Schedule 2 (Mapping); and identified as requiring assessment against the Landslide Hazard overlay code by the tables of assessment in Part 5 (Tables of assessment). All provisions in this code are assessment benchmarks for applicable assessable development.
Editor's Note-;Planning scheme policy 9 for assessment of natural hazards includes guidance for preparing a site specific geo-technical analysis.
8.2.8.2	Purpose and overall outcomes
The purpose of the Landslide Hazard overlay code is to ensure: development avoids or mitigates the potential adverse impacts of landslide hazard on people, property, community, economic activity and the environment; and development on steep land is avoided or limited in scale and intensity and is sensitively located and designed to minimise adverse impacts on landscape character, scenic amenity, environment and public safety. The overall outcomes sought for the Landslide Hazard overlay code are: Development in areas at risk from landslide hazard is compatible with the nature of the hazard. Development is resilient to landslide hazards by ensuring siting, design and access responds to and minimises potential risks to people, property and the environment. Natural processes and the protective function of landforms and vegetation are maintained in landslide hazard areas. Development avoids the release of hazard materials as a result of landslide hazard events. Development supports and does not unduly burden disaster management response or recovery capacity and capabilities. Development directly, indirectly or cumulatively avoids an unacceptable increase in the extent or severity of landslide hazards on the site or to other properties. Development on steep land occurs only where scenic amenity, landscape character and environmental quality and integrity is maintained and safe and efficient access can be provided.
8.2.8.3	Assessment Criteria
Table 8.2.8.3.1 - Criteria for assessment
	 Performance outcomes	Acceptable outcomes	Comments  Landslide hazard	 	 PO1 Development maintains the safety of people, property and hazardous materials stored in bulk from the risk of landslide.	AO1.1 Development, including associated access, is not located on land identified as a landslide hazard area on a Landslide Hazard Overlay Map; OR AO1.2 Development, including associated access, is located outside moderate, high and very high landslide hazard areas and areas with 15% slope or greater, as determined by a site-specific slope-analysis; Editor's Note—A site- specific geotechnical assessment may be used to demonstrate that although the proposed development is shown on the Landslide Hazard Overlay as being in the moderate, high or very high landslide hazard area, the landslide risk is low or very low. OR AO1.3 A site-specific geotechnical assessment is prepared by a registered professional engineer to certify that: the stability of the site, including associated buildings and infrastructure, will be maintained and operational for the life of the development; the site is not subject to the risk of landslide activity originating from other land, including land above the site; and development of the site will not increase the risk of landslide activity on other land; Editor's Note— PSP8 Natural Hazards provides further guidance on assessing landslide hazard. AND AO1.4 Any specific measures identified in a site specific geotechnical assessment for stabilising the site or development are to be fully implemented.	Complies – The location of the caretaker accommodation and shed is not located within the Landslide Hazard Area.  Essential community infrastructure	 	 PO2 Essential community infrastructure is is able to function effectively during and immediately after landslide events.	AO2.1 Development involving essential community infrastructure is not located within a landslide hazard area as identified on a Landslide Hazard Overlay Map; OR AO2.2 Development involving essential community infrastructure is located in a low or very low landslide hazard area and on land less than 15% slope, as determined by a site-specific slope-analysis; Editor's Note—A site-specific geotechnical assessment may be used to demonstrate that although the proposed development is shown on the Landslide Hazard Overlay as being in the moderate, high or very high landslide hazard area, the landslide risk is low or very low. AO2.3 A site-specific geotechnical assessment is prepared by a registered professional engineer to certify that: the long term stability of the site, including associated buildings and infrastructure, will be maintained and operational for the life of the development; access to the site will not be impeded by a landslide event; the community infrastructure will not be adversely affected by landslide activity originating from other land, including land above the site; and development of the site will not increase the risk of landslide activity on other land.	na  Sloping sites, landscape character and scenic amenity	 	 PO3 Development, including associated access, is designed and constructed to: be responsive to the natural topography and constraints imposed by the slope; retain the natural landforms, landscape character, vegetation, including the visual amenity of hill slopes and ridgelines; visually integrate into the streetscape and the natural surrounds; and ensure buildings and structures are not visually obtrusive, particularly from ridgelines, public open spaces, scenic routes and other critical vantage points, outside the site.	AO3.1 Buildings present no more than two storeys at any one point when viewed from the road or other public space. AO3.2 Buildings and associated accesses are not constructed on land with a slope greater than 25%. AO3.3 No additional lots intended to provide house sites are created on land with a slope of 25% or greater. AO3.4 Buildings are designed to follow the natural landform rather than modify it. Editor's note- Designs that step down the slope using split level construction or elevated construction on suspended floors are a preferred alternative to standard slab on ground construction reliant on cut and fill of sites. AO3.5 The extent of filling or excavation is revegetated immediately following completion of the works. AO3.6 Any building, including any associated car parking structure:- has a maximum undercroft height at the perimeter of the building of 3 metres above ground level; or incorporates landscape screening for the full height of any undercroft higher than 3 metres above ground level at the perimeter of the building. Editor's note- Vertical battens are also useful to enclose the undercroft area. AO3.7 On sloping sites roof lines are generally parallel with contours of the land and roof pitch does not exceed 15 degrees.	na 	 PO4 Development on sloping sites provides safe and efficient access for vehicles and pedestrians	AO4.1 Driveways are not steeper than 20% for more than 20 metres or one quarter of their length, whichever is the lesser, and not steeper than 25% in any location. AO4.2 Vehicle turning areas are provided at the end of driveways so that it is not necessary to reverse up or down driveways. AO4.3 Where a driveway is steeper than 20% in any part, it is provided with a slip-resistant surface.	na
