Limitations and assumptions The constraint analysis uses the following limitations and assumptions: > The maps show existing conditions within the corridor at a broad scale. > The analysis is based on available data, with limited field investigation. > The analysis covers a large corridor and a vast amount of spatial data. The broad level of the spatial data limits the details available at a local level.

Specific limitations within topic areas are discussed in the relevant sections below. It should be noted that any specific programs or

5.2.2 Community input Community comments and feedback relating to land use highlighted: >> The importance of the village settlement pattern adjacent to the Bells Line of Road. >> The amenity and value of villages, including Kurrajong Hills and the residential areas around Bowen Mountain and Grose Vale. >> The potential impacts on traffic congestion due to land use changes. >> The potential impacts of a bypass or motorway on local businesses (eg The Apple Bar, Tutti-Frutti, and The Turpentine Tree), and tourist attractions (eg Mount Tomah Botanic Gardens, orchards and slot canyons). >> Concerns about the length of the planning process. This could create uncertainty for prospective buyers of properties, who could be hesitant to purchase properties due to concern about the potential for future road widening.

>> In the eastern section, the moderate constraint highlights the North West Growth Centre and special use/community facilities such as the University of Western Sydney campus and TAFE NSW Western Sydney campus. Moderate constraint also reflects the occurrence of specialised agriculture associated with the flood plain, fruit growing and small lot settlements. >> In the western section, moderate constraint is associated with the Newnes State Forest and the small lot village settlements of Clarence and Little Hartley.

Low constraint areas >> Low constraint areas along the corridor reflect the presence of large rural lots. >> Low constraint in the eastern section reflects areas of infrastructure, including the Castlereagh Corridor.

5.2.4 Future investigations The land use analysis represents a snapshot of current and known future land uses. Any future planning or implementation of upgrade(s) will need to consider any planned changes to land use likely to occur, including any additional mining operations. As such, the land use constraint map will need to be updated, and will need to include detailed site-specific land use investigations. Additionally, native title (including land subject to native title claims) and Aboriginal-owned land will need to be considered for any future planning.

Each geotechnical aspect was classified as either a high, moderate, low or null constraint based on its influence on any future road upgrade. The final geotechnical constraints map is a composite of all the input constraint maps. Constraint classifications for each of the above aspects are summarised in Table 5.1.

5.3.2 Community input There were limited community concerns raised regarding geotechnical constraints. Specific concerns were raised about the preservation of slot canyons, which are considered to be irreplaceable heritage and recreational resources. The most popular canyons for visitors are very close to the road, and are less than a metre wide. Recreational canyons will need to be considered in future corridor development activities.

37 Bells Line of Road Long Term Strategic Corridor Plan

5.3.3 Mapping results Geotechnical constraints are shown in Figure 5.2.

High constraint areas >> High geotechnical constraint is associated with the more mountainous areas of the central and western sections, reflecting high slope as well as less stable geological units.

Moderate constraint areas >> Moderate constraint is associated with the flatter areas of the (eastern section) and Hartley Valley (western section), as well as isolated areas along the ridgeline (central section).

Low constraint areas >> Low constraint is generally restricted to small areas in the west, around the Newnes Plateau and small, isolated areas dispersed throughout the central section of the corridor.

5.3.4 Future investigations Planning for future road development in the corridor will require more detailed geotechnical assessment, looking specifically at route options and involving more detailed site reconnaissance. Specific geotechnical testing will also be required. Recreational canyons will need to be considered in any route development work and assessment.

Landscape character types Along the length of the route there are two broad landscape The Bells Line of Road corridor offers areas of visual richness categories: and a diverse range of experiences. These qualities are a function of climate, topography characterised by major changes > Urban/rural/settled landscapes clearly modified for human use in elevation and dramatic landforms, cultural and heritage items, or habitation. and the close proximity of unique vegetation. The corridor > Wilderness landscapes, mostly undisturbed bushland or forest. includes the Wollemi and Blue Mountains national parks and the Hawkesbury River. At a more detailed level, the corridor contains 17 discrete landscape character types. Each was assigned a constraint At both ends of the corridor are established towns with level (high, moderate, low) based on its sensitivity to any road embodied European heritage, the Macquarie towns of Richmond upgrades. The character types and constraint level classifications and Windsor at the outer extent of Sydney’s metropolitan are summarised in Table 5.2. footprint in the east and Lithgow in the west.

Mountain village High Urban centres in the central section that form a service base with schools, post offices, accommodation, general stores, etc. High street civic High Established centres that serve a civic function (eg local council chambers, police stations, courthouses, commercial and retail). Forest ridgeline High Areas where Bells Line of Road is on a ridgeline with forest immediately adjacent to the corridor, with very few built elements. Mountain pass High Areas along the road corridor associated with sharp changes in elevation and winding routes that provide a constantly changing visual experience. Forest flood plain High Flood plain areas with remnant or regrowth forest and agricultural land. The suitability of much of the surrounding land for agriculture means that large areas of this character type are rare. Forest mountain/national park High Areas in the central section with native vegetation, either untouched or regrowth forest. Spatial quality is enclosed. River/riparian Moderate Areas where a watercourse (eg Hawkesbury River) is large enough to have a visual presence as well as offering recreational opportunities such as water-skiing or parkland on its banks. Mountain rural Moderate Rural properties above the escarpment mainly in the central section, and, to a lesser extent, in the western section. Rural escarpment Moderate The area above the Hawkesbury River beyond North Richmond, characterised by a repeating pattern of agricultural land, residential areas, small shopping centres and remnant vegetation.

5.6.3 Mapping results Visual character constraints are shown in Figure 5.5.

High constraint areas > The visually dramatic bushland landscape within the national parks has great visual importance. Areas of high constraint are found predominantly in the central and western sections associated with the occurrence of native vegetation and high slopes of the Blue Mountains and Wollemi national parks.

Moderate constraint areas > Areas of moderate constraint in the eastern section reflect the flatter, relatively less vegetated areas. > Areas of moderate constraint in the western section are generally due to the presence of native vegetation.

Low constraint areas > Areas of low constraint are largely to the east of the Hawkesbury River and reflect less visually sensitive land uses (eg rural settlement) and relatively flatter, cleared areas.

Low constraint areas >> Low constraint is dispersed throughout the corridor. East of the Hawkesbury River, low constraint corresponds with land disturbed by rural and residential land uses. Within the Blue Mountains (west of the Hawkesbury River) low constraint areas correspond to particularly high-slope areas, reflecting less accessible areas.

5.7.4 Future investigations The limited information available on Aboriginal cultural heritage sites, together with the importance of this area indicates a need for a detailed, site-specific assessment of Aboriginal heritage as part of any future investigations. This would include targeted surveys and consultation with the Aboriginal community.

Low constraint areas > Generally, non-Aboriginal heritage is a low constraint across the eastern and western areas of the corridor.

5.8.4 Future investigations The constraint mapping provides a general overview and does not include all listed sites, due to some listings lacking specific location data. There are also likely to be a large number of unlisted sites with heritage significance occurring within the corridor. Future detailed investigations would need to identify these. Any future upgrade to Bells Line of Road will also require consideration of sites that are currently nominated for listing on the statutory registers. Such items/sites include the Blacktown Native Institution and the Colebee/Nurragingy Land Grant nominations on the State Heritage Register and the Hartley Valley, which is currently nominated for listing on the National Heritage List. Additionally, future planning will also need to consider the heritage listed walking trails (there are more than 300 trails) of the Blue Mountains World Heritage Area. Fieldwork will need to be undertaken as part of future planning. It is expected that the number of potential heritage items and archaeological sites will increase after detailed historical analysis and a site survey are undertaken. More detailed investigations will need to consider both direct and indirect impacts on heritage items, and consider design measures to minimise any impacts. Heritage building in Richmond

Moderate constraint areas > The large proportion of moderate constraint areas in the central and western sections reflects the occurrence of drinking water and the catchments of the Grose and Colo rivers (which are classified as wild rivers). The moderate constraints do not relate directly to watercourses but rather the catchments which feed them. Low constraint areas > Low constraint areas dominate the eastern section of the corridor, as there are no specific catchments in this area.

5.9.4 Future investigations Any planning for future upgrade(s) must consider potential Hawkesbury River near Richmond impacts on both the wild river and drinking water catchments, which are protected by State legislation and planning policies. Similarly, development within a drinking water catchment must demonstrate neutral or beneficial effects on water quality. Any road development in the corridor will require a site-specific soil and water management plan to address construction phase water quality and may require water quality monitoring to be undertaken. Water quality will also be an important component of the design of any future road development due to the need to avoid road contaminants entering sensitive waterways as a result of road operation. Planning and design will need to consider spill containment and the quality of day-to-day road runoff.

This constraint analysis suggests that any major road upgrade through the central and western parts of the Bells Line of Road corridor would be extremely challenging from an environmental, approvals and cost perspective.
