2.1 Introduction

This Chapter contains planning and design objectives and development controls applicable to all areas within the Alpine Sub-regions. The controls respond to the general character of the Alpine Region and the sensitivity of its alpine, sub-alpine and montane environments.

This Chapter provides the planning provisions that apply across all Sub-regions. It should be read in conjunction with Chapter 3 or Chapter 4, and the Carrying Capacity Framework at Chapter 5.

How to read and apply this chapter:

2.2 Built form and design

With the exception of development at Blue Cow which requires consideration of Section 2.7, C5, the objectives and controls in this part do not apply to recreation infrastructure, lifting facilities, monitoring stations, ski-slope huts, snow-making infrastructure, on-mountain guest amenity buildings (including food and beverage outlets and toilets) and any ancillary structure associated with these land uses.

2.2.1 Building siting and location

Objective
  1. Ensure the siting and location of development is:
    1. consistent with the desired future character of the relevant Sub-region, and
    2. where practical, undertaken on disturbed or partly disturbed land to minimise impacts on the environment and Aboriginal cultural heritage values, including places and objects of significance to Aboriginal peoples.
  2. Maintain key view corridors and vistas from public roads and other public vantage points and minimise visual intrusion on the landscape.
  3. Allow for the management of snow accumulation and associated building maintenance and access requirements.
  4. Ensure access appropriately addresses climatic design considerations throughout the year.
  5. Conserve existing significant natural landforms features including slopes, ridges and boulder outcrops/tors.
  6. Be appropriately designed to ensure visual privacy of occupants.
Controls

Siting development and topography

  1. Development is to be designed and sited to, where possible, avoid significant impacts on views and landscape features and habitats, e.g. boulder outcrops/tors, creeks, bogs and wetlands.
  2. Where practical, development is located within existing building footprints and other disturbed areas including infrastructure corridors.
  3. Buildings are sited and orientated to provide safe snow accumulation zones. Building entrances are snow and/or drip free to protect building occupants and visitors.
  4. Development is stepped in response to the natural topography to minimise the need for earthworks as shown in Figure 2. Stepped development considers snow deposition and equitable access.
  5. Development maintains ridgelines (see Figure 3) and natural vegetated backdrops.

Setbacks to access ways, roads and infrastructure

  1. Where there is an established setback from a road used to access the development, the front facade of buildings align with the neighbouring building setback (refer Figure 4 and Figure 5).
  2. Subject to site conditions and consideration of streetscape, amenity and environmental impacts, allowable encroachments within the setback may include detached structure such as waste structures and elements attached to the building, such as entry features or porticos, balconies, decks, pergolas, terraces or verandahs, window box treatments, bay windows or similar features, awnings or other features over a window and sun shading features and eaves.
  3. Buildings are set back from transport, utilities and snow-based infrastructure to ensure that amenity is preserved for visitors and to provide sufficient operating space for infrastructure, including oversnow and snow-clearing operations.

Setbacks and building separation

  1. Buildings are sited and orientated with consideration for occupant privacy.
  2. Setbacks and separation distances between buildings ensure that new development does not impede existing public pedestrian access and allows for the management of snow accumulation between buildings while avoiding obstruction of building entry and exit points.

Note: Buildings may be clustered to address snow management.

2.2.2 Building height and scale

Objectives
  1. Reinforce the desired future character and scale of the relevant Sub-region, except where sites have specific height controls.
  2. Building height maintains view corridors and key vistas from public spaces and vantage points.
  3. Ensure building height does not unreasonably dominate the natural landform, vegetation, or other features of the landscape.
  4. Maximise solar access to public spaces.
Controls
  1. The height of buildings is consistent with those specified for the relevant Sub-region. Where there is no specified height for buildings, the development is consistent with the established heights that characterise the Sub-region, and
  2. Where reasonable, the height and scale of buildings maintain key view corridors and vistas identified within the future character statements and avoid reducing solar access to identified public spaces within the Sub-region.

2.2.3 Building design

Objectives
  1. Provide a high quality of building design that incorporates architectural elements of the Sub-region, responds to the landscape setting of the Sub-region and is appropriate for the prevailing alpine, sub-alpine or montane conditions.
  2. Ensure development responds to public spaces through activation, appropriate public domain treatments for year-round conditions, and minimise any reduction in solar access.
  3. Ensure individual buildings contribute positively to the desired future character of Sub-regions with regard to bulk, form, style, scale, setbacks and materials whilst enabling innovative and contemporary design.
  4. Encourage contemporary building materials that complement and enhance the character of the relevant Sub-region.
  5. Ensure building materials, colour and finishes are appropriate for the prevailing alpine, sub- alpine or montane setting and minimise glare and reflection.
Controls
  1. Development complies with Australian Standard AS1170.3.
  2. Development provides sufficient space for storage of the type and number of bins required to meet the needs of the development.
  3. Building design is consistent with the local character and the building style described in the Sub-region desired future character statement (refer to Appendix A).

Relationship to public spaces

  1. Car parking structures are integrated into the design of the building. Garages and undercroft parking structures do not dominate building facades.
  2. Buildings located adjacent to public spaces:
    1. address and activate public spaces with entrances, lobbies and windows. Where entertainment, food and drink premises are located adjacent to public spaces, outdoor seating appropriate to prevailing climatic conditions are considered, and
    2. provide a visually attractive and functional interface with public spaces, appropriate to the alpine, sub-alpine or montane climatic conditions in the relevant Sub-region.

Roof design

  1. Roof design, including materials, pitch and plane, overhangs, and stormwater drainage solutions prevent snow accumulation over building entrances, walkways, roads and driveways, or in public spaces or other areas where people congregate.
  2. Roof materials comprise corrugated iron or profiled metal and have low reflectivity.

NOTE: Shedding snow safely to ground melt zones is the preferred method of managing snow accumulation.

Articulation

  1. Buildings avoid blank walls and be articulated. Examples of achieving building articulation are illustrated in Figure 6 to Figure 9.

Building entries

  1. Building entries are designed and located to be clearly visible from the street/road or access point, and easily identifiable and accessible in difficult weather conditions, to provide shelter and a transition space to the interior and to be snow and drip free, incorporating a roof structure or design element that prevents snow shedding at the entrance.

Building materials

  1. Building materials and finishes maximise thermal comfort and minimise energy consumption and are hard wearing, long lasting and of a high quality and low maintenance to withstand the snow, rain, wind and high levels of UV exposure encountered in alpine, sub-alpine and montane climates.
  2. Building facade design achieves a balance between solid and void elements, avoids large expanses of a single material and incorporates different colours and patterns and are articulated using techniques such as projections and recesses.
  3. Building facade wall materials may comprise a mixture of profiled metal, timber, stone, plastered masonry, bagged and painted concrete, or other appropriate materials. Natural stonework, such as granite or similar, is incorporated into the ground floor facade, particularly in areas readily viewed from the public domain. Natural cleft or rock face stone such as granite and basalt are used on 15% of lower levels.
  4. Colours for large expanses of external wall are be recessive and sympathetic to the landscape character.
  5. Sustainable building materials are encouraged where they are appropriate for the prevailing climatic conditions and environment in the Sub-region.

Main Range Management Unit

  1. Development that may be viewed from the Main Range Management Unit (as defined in the Kosciuszko National Park PoM) considers:
    1. colour palette that blends with the prevailing landscape,
    2. appropriate materials that minimise reflectivity and prominence, and
    3. design and siting of development.

Views of the top of mountain in Charlotte Pass Alpine Resort, Thredbo Alpine Resort, and Perisher Range Alpine Resort are particularly important. The majority of Guthega village can be viewed along with Blue Cow Terminal from the Main Range and will require particular consideration.

2.3 Amenity

With the exception of development at Blue Cow which requires consideration of Section 2.7, C5, the objectives and controls in this part do not apply to recreation infrastructure, lifting facilities, monitoring stations, ski-slope huts, snow-making infrastructure, on-mountain guest amenity buildings (including food and beverage outlets and toilets) and any ancillary structure associated with these land uses.

Objectives
  1. Ensure high levels of amenity for accommodation occupants in terms of solar access, visual and acoustic privacy and avoidance of odour problems.
  2. Ensure new development is sited and designed to protect solar access to existing and future key public spaces and habitable rooms and common living areas within the development and nearby, existing development, balanced against opportunities to provide views from development.
  3. Preserve and enhance view corridors and significant vistas that are viewed from publicly accessible vantage points, including those identified in the Alpine Sub-regions, and promote view sharing between developments to key landscape, such as ridgelines and skyline.
  4. Minimise impacts from lighting on occupants and the natural environment.
Controls

Solar access and overshadowing

  1. Tourist and visitor accommodation is designed and orientated to enhance solar access to the common living areas of the development and primary windows of both the development and adjoining developments.
  2. Development is designed to minimise overshadowing of public spaces, particularly those that are used by persons to congregate and key open spaces utilised during the snow season. New development does not reduce solar access to public spaces and communal areas to less than two hours between 11am and 3pm on 21 June.

Visual privacy

  1. Development of tourist and visitor accommodation, as well as staff accommodation, minimises privacy impacts on habitable rooms within the same or adjacent development through a combination of the following:
    1. offsetting the location of habitable windows between buildings (where possible),
    2. providing setbacks and separation between buildings,
    3. locating balconies to avoid direct views to, or overlooking of, adjacent balconies, or
    4. use of privacy screening, opaque windows or other such devices.

Examples of proposed approaches and building separations are illustrated in Figure 10.

Noise and odour

  1. Building location, design and layout considers the following:
    1. impact from external noise or odour sources such as food and drink premises, plant and machinery or infrastructure on the occupants of the building,
    2. noise and odour transmission between different uses within the building, and
    3. the potential impact of noise or odour upon adjoining uses.

Lighting

  1. Lighting does not unreasonably impact on the amenity of building occupants, particularly in sleeping locations, or the natural environment.
  2. Development minimises light spillage visible from the Main Range Management Unit.
Example of design measures to minimise visual privacy impacts between buildings, including building separation, offsetting of windows and balconies and use of privacy screens.
Figure 10. Examples of building separation, setbacks, privacy screening, window offsetting and balcony placement to ensure visual privacy

2.4 On-mountain development and infrastructure

The objectives and controls in this part apply to development for the purposes of lifting facilities, monitoring stations, ski-slope huts, snow-making infrastructure, infrastructure facilities and recreation infrastructure.

Objectives
  1. Allow for a mix of summer and winter recreational opportunities for a range of visitor skill levels and types that enhances the particular Alpine Sub-region character.
  2. Allow for on-mountain development and infrastructure that is environmentally sustainable and meets visitor needs.
  3. Ensure ease and efficiency of circulation, adequacy of public facilities, lift and trail capacity and public safety to enhance amenity in all seasons.
Controls
  1. Upgrades to lifting infrastructure and snowmaking infrastructure prioritise development that limits disturbance to existing alignments. Where this is not practical or will result in adverse impact on amenity or efficiency, development may occur outside of existing alignments.
  2. Aerial lifts are to be used in place of surface lifts, unless it can be demonstrated that a surface lift is necessary for operational reasons and that the surface lift will result in minimal environmental impacts. Consideration will be given to environmental impacts and operational outcomes in consideration of the most appropriate form of lifting infrastructure and any associated cabling.
  3. Walking trails and infrastructure are designed along existing disturbed areas such as ski slopes. Where this is not practical, development may occur outside of existing disturbed areas.
  4. All summer and winter on-mountain developments and infrastructure make efficient use of the natural terrain by limiting terrain modification to where it is essential for safety, to resolve environmental issues or to improve visitor experience.

2.5 Minor alterations and additions

This section describes the relevant development controls applicable to ‘alterations, additions and minor works to existing buildings’. Such development does not need to consider other sections of this DCP (except Section 2.7 Historic Heritage).

NOTE: Development that is covered by this section requires a development application to be submitted to the Department. Nothing in this section precludes development from being carried out as either exempt or complying development that meets the requirements of Part 4.3 of the Precincts - Regional SEPP and development standards under either Schedule 2 (exempt development) or Schedule 3 (complying development).

Alterations, additions and minor works to existing buildings is, for the purposes of this section of the DCP, development that is carried out on any use for the following forms of internal and external building alterations:

Internal building alterations to construct, install, replace or renovate building elements such as:

  1. an internal window, doorway, wall, ceiling or floor lining, frame members, stairs and stairwells,
  2. kitchen or bathroom, built-in fixtures including a vanity, cupboard or wardrobe,
  3. sanitary fixture, including a grease trap,
  4. shelving or racking, partition, workstation or counter.

External building alterations to construct, install, replace or renovate building elements such as:

  1. painting, plastering, cement rendering, cladding, attaching fittings or decorative work,
  2. wall or roof cladding (including structural wall),
  3. a door, security screen or grille on a door or window, including enlargement/reduction of existing doors.
  4. security door or balustrade,
  5. entry features or porticos, balconies, decks, pergolas, terraces or verandahs, window box treatments, bay windows or similar features, awnings or other features,
  6. external window, glazed area or door, including enlargement/reduction of existing windows.
Objectives
  1. Facilitate the orderly development of land.
  2. Ensure the design of alterations, additions and minor works to existing buildings (including those for fire or accessibility upgrades) do not detract from the amenity of the surrounding buildings and the desired future character of the Sub-region.
Controls
  1. Does not increase the height of the existing development or encroach into established setbacks, unless consistent with relevant controls in Chapter 2.2 and the relevant Sub-region.
  2. Development that involves alterations to improve equitable access to a building (including lifts, ramps, and stairs) is sympathetically integrated into the existing building and retains its original character and landscaped areas.
  3. Development on ridgelines does not result in any significant adverse visual impact.
  4. Development involving external works must not include excavation or filling, unless the alterations and additions are located within the existing building envelope.
  5. Building materials and colours are consistent with the existing building materials or sympathetic with the existing character of the immediate locality.
  6. Development relating to heritage items listed in the Precincts-Regional SEPP 2021 is consistent with Section 2.7 Historic Heritage.
  7. Development on land identified as bushfire prone must address the bushfire protection measures in the NSW RFS publication Planning for Bush Fire Protection (or equivalent)
Articulation zone

Means an area within a lease boundary forward of the building line within which building elements are permitted to be located.

2.6 Signage and Wayfinding

Objectives
  1. Ensure signage is in keeping with the scale, character and architectural style or features of a building or location.
  2. Provide well designed and suitably located signage that allows for the identification of a business, land use or activity which the signage relates.
  3. Ensure a coordinated approach to signage where a development has multiple tenancies.
  4. Protect landscape qualities and key view corridors and vistas from inappropriate signage.
  5. Ensure signage does not adversely impact on the locality or cause a distraction to road users.
  6. Ensure signage does not create conflicts or safety problems for pedestrians.
  7. Wayfinding and interpretive signage are appropriately positioned, fit for purpose, consistent with road safety principles and existing signage and sympathetic to the landscape and heritage, whilst utilising universal design principles, enhancing scenic qualities, protecting views and vistas and reducing visual clutter.
Controls

General controls

  1. Signage is to recognise the legitimate needs for directional advice, business identification and promotion.
  2. Signage is to complement and be compatible with the development on which it is situated, adjoining development and the character of the area.
  3. The size and shape of a signage is to relate and be proportional to the size of the building or space to which it is to be attached. Larger building facades are capable of accommodating larger signs without detracting from the appearance of the building.
  4. Signage is to make up no more than 20 percent of the building facade.
  5. Signage is not to dominate or obscure a building or its architectural features. Advertising and signage should highlight and reinforce architectural details.
  6. Signage is not to negatively impact on road safety.
  7. Signage erected or displayed on heritage items is not to detract from the architectural character and heritage significance of the buildings.
  8. Signage is not to dominate or obscure landscape qualities or key view corridors and vistas.
  9. Signage is to be installed with consideration of impacts on native trees and other vegetation, including any immediate or ongoing removal or pruning of vegetation for visibility of the signage.

Illuminated signs

  1. Signs should not detract from the building’s architecture during daylight.
  2. Illumination (including cabling) must be concealed, integral with the sign or provided by carefully designed remote or spot lighting.
  3. Adjustable light intensity must be installed if required by the consent authority.
  4. Illumination is limited to the hours of 7am to 10pm/close of business (whichever is the lesser).

Signage and road safety

  1. Signage is considered to impact on road safety detrimentally and is undesirable if it:
    1. obscures or interferes with road traffic signs, signals, the view of oncoming vehicles or pedestrians or road hazards or obstructions
    2. use words like ‘stop’ or other directions that could be confused with traffic signs
    3. has variable messages or lighting intensity that impairs or distracts drivers
    4. is located where drivers need greater concentration, such as at major intersections or merging/diverging lanes.

Inappropriate signage

  1. The following forms of signage are not appropriate and will not be supported:
    1. roof signs
    2. sky signs controlled from the land, including inflatable balloons
    3. signs painted on or applied to the roof
    4. moving and flashing signs
    5. variable or video message signs
    6. canvas, calico, or similar signs (except temporary signs)
    7. hoardings (except during construction)
    8. billboards
    9. posters (except within frames attached to structures)
    10. pole or pylon signs (except for certain uses, max height 7.0m)
    11. vertical or horizontal projecting signs
    12. fin signs

Wayfinding signage

  1. To assist with the public access and understanding of the long First Nations association with the land, Aboriginal cultural items such as artistic design or names is incorporated into wayfinding signage and/or interpretive panels where appropriate. Interpretation initiatives include consultation with Aboriginal community members.
  2. Design guidance for wayfinding signage considers how building design, siting, and materials could form part of a broader interpretation strategy, including consideration of Connection to Country and Return to Country.

2.7 Transport, car parking and access

Objectives
  1. Support improved public transport year round to the Sub-regions, including regular bus access from Jindabyne to Perisher Range Alpine Resort Sub-region, Thredbo Alpine Resort Sub-region, and Charlotte Pass Alpine Resort Sub-region in the summer.
  2. Ensure car parking minimises environmental impact and does not compromise the Sub-region character or visually detract from the desired future character.
  3. Provide opportunities for improved walking and cycle connections and supporting infrastructure throughout the Sub-regions.
  4. Ensure Sub-region village road and public domain design utilises durable, low-maintenance materials that can tolerate alpine, sub-alpine and montane climate variation and snow-related usage and operations.
  5. Ensure car parking, vehicle access, and loading, service and waste facilities do not compromise pedestrian safety.
  6. Ensure development provides improved access and parking, and that facilities consider both winter and summer activities and the equipment required for them, such as snow related activities, mountain biking, hiking, and micromobility.
Controls

Car parking and services/loading

  1. Development is consistent with the following maximum car parking rates:
    1. hotel or motel accommodation (including pubs where accommodation is provided) and eco-tourist facilities:
      1. one space per unit/room, and
      2. two parking spaces for the manager.
    2. backpackers’ accommodation: assessed on merit.
    3. serviced apartments:
      1. one parking space per one-bedroom unit, or
      2. two parking spaces per two or more-bedroom unit, and
      3. two parking spaces for the manager.
    4. lodges: two parking spaces per unit.
    5. commercial premises (including offices), shops, restaurants and cafes and other development not specified in C1: Separate parking for individual developments will generally not be required as the majority of customers will be drawn from the village accommodation. A detailed parking and traffic impact assessment by a suitably qualified traffic specialist may be required to substantiate proposed parking provision.
  2. Car parking provision minimises substantial earthworks and the loss of significant native vegetation and ecological communities where possible.
  3. Where car parking is to be provided in association with individual accommodation buildings, it is to be located within the lease boundary or an associated licence area.
  4. The provision of tandem parking or car stackers will be considered for:
    1. club and commercial lodge accommodation where the operator manages the parking of these vehicles, and
    2. self-contained accommodation where the parking is allocated to a specific unit.
  5. Servicing and waste facilities are integrated into the overall development or are located or screened to minimise visibility from public spaces, without compromising accessibility for the vehicles that are required to access them.
  6. The design of car parking, loading, service and waste facilities minimise the potential for pedestrian and vehicle (including oversnow) conflicts.
  7. Design of car parking and village road treatment ensures appropriate storage and clearing arrangements for snow build-up, considers road paving and stormwater infrastructure that reduces run-off turbidity, considers the use of storm-ceptors or other measures to prevent pollution from car parks and other paved areas and ensures compliance with the requirements of Chapter 2.10 Stormwater Management.

Pedestrian and cycling facilities

  1. New development, including new car parking areas, provides sufficient bicycle and micromobility parking, or alternatively a bicycle rack for use by the whole of the development (where possible).

2.8 Aboriginal cultural heritage

Objectives
  1. Management of Aboriginal cultural heritage is based on the principles of protection, maintenance, and enhancement, to preserve the significance of landscapes, vegetation and objects of significance to Aboriginal people.
  2. Protect Aboriginal Objects and Aboriginal Places of heritage significance by minimising the likelihood of disturbance from development.
Controls
  1. The location of a development in relation to a heritage management zone in the DCP maps (see Appendix D) will determine the nature and level of further assessment required. Development is consistent with the Due Diligence Code of Practice for the Protection of Aboriginal Objects in NSW.
  2. An erosion and sediment control plan prepared as part of the application considers measures to minimise disturbance to Aboriginal cultural heritage objects. This may include through the use of soft engineering solutions such as the placing of hay bales or coir logs on the surface.

2.9 Historic heritage

Objectives
  1. Support and ensure the long-term conservation of heritage items, associated fabric, views, and the heritage values of items and places through retention and interpretation.
  2. Ensure development of heritage items is based on an understanding of the heritage significance of the particular heritage item(s).
  3. Ensure significant features of heritage items are retained and that development, with regard to bulk, form, style, character, scale, setbacks and materials, is sympathetic to these features.
Controls
  1. Where an adopted Conservation Management Plan (CMP) is in place for a heritage item, the development is consistent with that CMP.
  2. Heritage items, wherever possible, are incorporated into the design of the public domain in the Alpine Sub-regions where they are publicly accessible and can be appreciated by all.
  3. Redevelopment or upgrades to a heritage item listed in the Precincts-Regional SEPP 2021 removes inappropriate or unsympathetic alterations and additions to heritage items and reinstates significant missing details and building elements where possible.
  4. Development on or adjacent to a heritage item listed in the Precincts-Regional SEPP 2021:
    1. ensures that impacts to the heritage item are minimised through siting, the provision of curtilages, selection of appropriate materials and finishes, use of landscaping and fencing or other measures supported by a Statement of Heritage Impact, and
    2. provides further heritage assessment where the development is likely to have adverse impact on a heritage item or its value. Development is considered to have a material affect if it involves:
      1. the full or partial demolition of a building
      2. major alterations or additions involving the introduction of major new elements or harm to significant portions of original fabric
      3. minor alterations where significant fabric may be harmed, or elements added to original fabric that diminishes its value
      4. major adverse impacts, such as obscuring key views or dominating a heritage item, or the removal of evidence of significant historical associations, and
      5. impact to significant archaeological deposits.

2.10 Landscaping

Objectives
  1. Provide strong visual identity by including plants with defined form and foliage to help strengthen a pedestrian orientated environment.
Controls
  1. Landscaping and rehabilitation are undertaken for new development in accordance with Rehabilitation Guidelines for the Resort Areas of Kosciuszko National Park (Rehab Guidelines) (Dept. Environment and Climate Change 2007) as updated or replaced from time to time, including where stabilising sites and preparing them for planting, selecting and planting species and maintaining plantings following development.

2.11 Stormwater management

Objectives
  1. Retain natural features of waterways for stormwater source management and control, in preference over structural or ‘end of pipe’ solutions.
  2. Where appropriate, utilise best practice for stormwater management, including capture, treatment, and reuse of rainwater and release at appropriate flow rates.
  3. Stormwater drainage networks include both underground and above ground drainage infrastructure and facility for removing debris and contamination.
Controls
  1. Development is to have a neutral or beneficial impact on surface and groundwater quality, including in watercourses and associated riparian vegetation and receiving waters.
  2. All new underground stormwater pit and pipe drainage is designed to capture and convey the 5% annual exceedance probability (AEP) design event flow plus 20%.
  3. All overland flow paths are designed to safely convey the 1% AEP flows plus 50% of underground pipe flows (based on the assumption that the underground pipe has a reduced capacity of 50% due to blockage of surface inlet pits).
  4. All development that will affect existing stormwater infrastructure:
    1. limit site discharge to predevelopment flows for the 10% AEP and below, and
    2. provide a safe (where practical limit velocities to 2m/s) overland flow path for stormwater runoff for events greater than the 10% AEP up to and including the 1% AEP including consideration of climate change projections for rainfall intensity. This ensures that where pipes are blocked by frozen water there is a defined overland flow path to ensure water escapes and does not impact development.
  5. Development allows for the treatment of stormwater runoff during summer months and the storage of snow push during winter months through:
    1. edge treatments (rock or concrete lined channels and basins) to store snow push, reduce velocities of melted water and allow for sediment to be captured in channels or basins (designed to allow for removal of sediment by heavy machinery following winter months) before discharge into nearby watercourses
    2. vegetated buffer strips on roads to capture sediments in storm and snow runoff, or
    3. site specific stormwater pollution devices to capture runoff from large, paved areas such as car parks. Figure 11 provides examples of these treatments.

2.12 Flooding

The objectives and controls in this apply to flood prone land. Flood prone land is identified in Appendix F.

Objectives
  1. Development within flood prone land (FPL) is consistent with the Flood Risk Management Manual (2023).
  2. Development is sited, designed, and located to avoid or mitigate the flood risk to people, property and infrastructure both within the lease boundary and beyond the boundary, and ensure flood safe access is available.
  3. Development activities do not reduce the capacity of the floodplain to store floodwaters, impede floodwater flow, or alter flood patterns in a way that compromises public safety or access to evacuation routes.
  4. Protect the integrity of floodplains and floodway, including riparian vegetation, fluvial geomorphologic environmental processes and water quality.
Controls
  1. Development within FPL (refer Appendix F) satisfies the following:
    1. ensure flood safe access can be achieved through ensuring depth of flooding over vehicular driveways and roads is limited to approximately 0.3 metres and velocities of less than two metres per second. Where this not be achieved, development demonstrates how safe access can be achieved in the event of flooding;
    2. set habitable floor levels at a minimum of the flood planning level of 1% AEP plus a freeboard of 500mm and maximum of three metres above ground level; and
    3. ensure all structures have flood compatible building components if below the 1% AEP Flood Level plus 500mm Freeboard.
  2. Where the flood planning level (FPL) is above the PMF level then the lower of the two values is be adopted. Refer to Figure 12 which shows the minimum habitable floor level recommended when the PMF is below the FPL.
  3. For tourist and visitor accommodation, a risk-based approach is adopted. Where a risk-based approach is applied the development satisfies the following:
    1. development requires the preparation of a flood emergency management plan by a suitably qualified consultant to address the risks of flooding and demonstrate compliance with the following principles:
      1. development planned and operated in recognition of the full range of potential floods up to and including the probable maximum flood (PMF)
      2. ensure development on the floodplain is consistent with the Flood Risk Management Manual (2023)
      3. tourist accommodation operators, developers and park occupants are conscious of the potential flood hazard and consequent risk associated with the use and development of land within the floodplain
      4. all land uses and essential services are appropriately sited and designed in recognition of all potential floods
      5. does not place an unacceptable financial burden on leaseholders or the community and
      6. restrict intensification of development and activity in high flood risk precincts, and where possible to reduce continued occupancy by long-term residents (i.e. staff and managers) within high flood risk precincts.
    2. to protect the integrity of floodplains and floodways, including riparian vegetation, fluvial geomorphologic environmental processes and water quality, where the development is located within the PMF flood extent but not within the FPL. Flood extent consideration is given to the H4 hazard vulnerability limiting depth and velocities (refer to Table 1) as part of the structural design of the building/structure.
    3. where the development is located within the FPL minimum habitable floor levels are set at the flood planning level of 1% AEP plus a freeboard of 500mm and the design of structures with consideration of the hazard vulnerability classification for the land as per the map and defined in Table 1.
    4. where development is located within the 1% AEP flood extent the hazard vulnerability classification for the land in Table 1 and the special flood considerations include that the development will not affect the safe occupation of and efficient evacuation of people in the event of a flood, incorporates appropriate measures to manage risk to life from flood and will not adversely affect the environment in the event of a flood.
  4. A site-specific flood assessment that demonstrates compliance with this Chapter is to be submitted for development:
    1. within sites that are covered by existing flood mapping
    2. that intersects or blocks a watercourse channel which comprises the bed and banks of the watercourse (to the highest bank) with a stream order of two or greater, or
    3. that is located within the riparian zone of a watercourse with a stream order of four or greater. Where the riparian zone is defined as the vegetated riparian zone (VRZ) adjoining the channel (NoW, 2012). A fourth order stream includes estuaries, wetlands and parts of rivers influenced by tidal waters. (NoW, 2012) For a fourth order stream the riparian zone is recommended to comprise of 40 metres each side of the channel.

2.13 Biodiversity, natural water systems and water sensitive urban design

Objectives
  1. Minimise impacts of development, including associated stormwater runoff, to areas of high biodiversity value within and along watercourses and riparian corridors. This includes the species of aquatic and terrestrial fauna that the areas of high biodiversity value support.
  2. Protect and enhance existing natural or constructed drainage networks including channel bed and banks by controlling the magnitude and duration of erosive flows.
Controls

All development

  1. Except where development within the vegetated riparian zone (VRZ) is unavoidable or allowable under the Guidelines for Controlled Activity Approvals, or equivalent under the Water Management Act 2000, development is designed and sited to minimise disturbance of the of the natural drainage system and avoid VRZs, shown in Figure 13.
  2. Development is designed and sited to avoid or minimise impacts on significant natural landform features including slopes, ridges and rock outcrops.
  3. Development that may result in biodiversity impacts (excluding vegetation removal) is supported by rehabilitation and monitoring measures consistent with the Rehab Guidelines.
  4. Impervious surfaces are minimised and soft landscaping incorporated to the maximum practical extent to promote water infiltration and reduce stormwater run-off.
  5. Except as part of minor developments or alterations and additions and where site conditions allow, water sensitive urban design (WSUD) measures are incorporated into development to minimise adverse impacts on sensitive and water-dependent ecosystems such as bogs and fens. Within the Alpine Region, this includes all areas of alpine and sub-alpine peatlands, damp herb fields and fens.
  6. Stormwater runoff from communal areas for new development is treated through communal WSUD measures to ensure water pollution is avoided.

All development excluding on-mountain food and beverage facilities, lifting facilities, ski slope huts, snow-making infrastructure and associated buildings

  1. Where possible, development is located near existing infrastructure and concentrated in and around already disturbed areas or areas of low ecological value to avoid habitat fragmentation. This includes associated infrastructure and services.
  2. Development is setback from significant landscape features and habitats, including existing creeks, bogs and wetlands to provide an appropriate buffer zone. Such buffer zones are provided in accordance with the requirements under Guidelines for riparian corridors on waterfront land. Exceptions will be considered where new development is located within an existing building footprint and/or disturbed areas.

2.14 Bushfire prone land

Objectives
  1. Ensure bushfire management measures are balanced with the protection of areas of environmental and cultural significance.
Controls
  1. Development on land identified as bush fire prone land on the Bush Fire Prone Land Map must address the bush fire protection measures in Planning for Bushfire Protection 2019 (or equivalent), ensuring that impacts on biodiversity and heritage are considered as part of and balanced against any required Asset Protection Zones (APZs).

2.15 Climate and ecologically sustainable development

Objectives
  1. Contribute to the wider goal of achieving a carbon neutral Alpine Region in operation with electrified development and 100% renewable energy by 2050.
  2. Enable a climate resilient Alpine Region with promotion of year-round tourism activities.
  3. Provide for the efficient use of natural resources and reduce the consumption of water and fossil fuels.
  4. Improve sustainability of building materials through reduction, re-use and recycling of materials, resources and building components.
Controls
  1. New commercial development and tourist and visitor accommodation:
    1. adopts a sustainable design framework. Development is encouraged to achieve the highest possible rating, by way of Green Star Building and/or NABERS Energy Commitment Agreement and/or Climate Active Carbon Neutral Certification
    2. contributes towards the transition away from fossil fuel usage including through the use of electric induction cooktops, electric heat pumps for space heating and electric hot water supply (solar, electric heat pump or electric instantaneous heating systems)
    3. incorporates the use of on-site renewable energy generation, with consideration of snow-loading impacts and orientation to maximise output, and
    4. utilises thermal mass principles to reduce energy demand through:
      1. insulation with 'R' value of 3.5 or more for ceilings, 2.5 or more for walls and two or more for raised or lightweight-type floors
      2. a concrete slab-on-ground with an in-slab or in-screed heating or cooling system, with insulation with an R-Value greater than or equal to 1.0, installed around the vertical edge of its perimeter, and
      3. install double glazed or higher order windows, glass doors and skylights (Insulated Glass Units).
