EXECUTIVE SUMMARY

This Review of Environmental Factors (REF) provides an assessment against the requirements of Part 5 of the Environmental Planning & Assessment Act 1979 (Act) for the following road work projects to be undertaken by Camden Council (Council): 1.

Upgrade the intersection of Camden Valley Way, Kirkham Lane and Liz Kernohan Drive at Elderslie (commissioning of a signalised intersection). A length of Kirkham Lane will also be upgraded by way of widening and resurfacing as part of this project.

Construct a roundabout at the corner of Camden Valley Way and Hilder Street at Elderslie.

Utility considerations including relocation telecommunications infrastructure.

Any heritage impacts associated with the proposed development on identified heritage significant sites.

sewer,

water,

electricity

and

This amendment to the REF is to address the inclusion of a construction compound on Lot 1 DP 914674 located at the corner of Camden Valley Way and Hilder Street. Approximately 3,700m2 of land in the north-eastern part of Lot 1 DP 914674 is proposed to be used for the construction compound for the temporary storage of construction materials and machinery during works. While Lot 1 DP 914674 was previously included in the REF for the road upgrade works, the impact of the construction compound area had not been considered. The amended REF (Revision H) includes these considerations and any additional mitigation measures, as required. Indicative location of the construction compounds are provided in Appendix I. As exact details of the sheds, offices etc have not been provided, it is assumed that these structures will be constructed under the provisions for exempt developments in State Environmental Planning Policy (Transport and Infrastructure) 2021. A further amendment to the REF will be required if the proposed scope of works is outside the standards for exempt developments. In reviewing the works proposed against the relevant provision of the Act, Camden Council is both a public authority proponent under section 5.3 and the determining authority following section 5.1. As such, the proposed works are considered Development permitted without consent following a review of the Act, the Environmental Planning and Assessment Regulations 2021 (Regulation), and the State Environmental Planning Policy (Transport and Infrastructure) 2021, enabling the works to be undertaken without consent. All matters affecting, or likely to affect, the environment by the proposed activity included the following: Transformation of a Locality The works being proposed within the already disturbed landform is not considered to transform the locality. Minor changes to the landform are envisaged by virtue of the excavations and vegetation clearing proposed. The Endangering of a Species Species are not considered to be endangered by the proposed development. The works are contained within the existing disturbed landform and is not mapped containing biodiversity values.

Long-Term Effects on the Environment The proposed activity is not considered to result in long-term effects on the environment by virtue of the activity proposed. Degradation of the Quality of the Environment Earthworks and the provision of a road extension may result in alteration to the natural environmental processes. It is recommended that that the works are undertaken with the recommendation of a suitably qualified engineer to ensure hydrology of the locality is maintained. Risk to the safety of the environment Risk to the safety of the environment is not envisaged subject to adequate environmental protection measures be implemented during the relevant works. Reduction in the range of beneficial uses of the environment Given the disturbed landform, reduction in the range of beneficial uses of the environment are not envisaged by virtue of the activity proposed. Landform, Geology and Soils The proposal has the potential to generate sediment during rainfall events due to ground disturbance, including excavation and vegetation removal. Sediment mobilisation from soil deposited on road pavements during works is a further potential impact. Hydrology, Flooding and Water Quality During construction, the disturbance of soils would create the potential for the mobilisation of sediment. The potential for accidental spills and leaks creates a further issue. These potential impacts are considered manageable and have been addressed through the proposed safeguards and mitigation measures. During operation, the proposal would result in some increase in impermeable hard surface areas and would increase capture in wet weather events by a small amount. Impacts from the broader area are likely to be negligible. Sediment runoff from earthwork and construction may impact stormwater quality and quantity by introducing silt and other pollutants and increase volume into nearby water bodies. To address and mitigate potential environmental impacts, the REF recommends the preparation of a Construction Environment Management Plan prior to the commencement of works with details to address direct actions to be undertaken by construction contractors to ensure runoffs are to be captured and treated before entering natural waterways and water quality in waterways is managed and maintained. Air Quality Construction activities including earthworks can generate dust and particulate matter emissions which can contribute to localized air pollution if not mitigated effectively. As part of construction works, dust control measures are to be addressed in a Construction Environment Management Plan (CEMP) and implemented by the contractor. The use of paints, solvents, and adhesives during construction may release Volatile Organic Compounds (VOCs) into the air which can affect the air quality within the locality. During construction works, air quality monitoring systems are to be installed, and green infrastructure utilized for natural air filtration.

The production and transportation of building materials, as well as construction activities, can produce carbon and other greenhouse gases. As part of construction works, consideration will be given to sustainable building materials and construction practices to reduce emissions during the construction phase. The proposal is anticipated to result in minor emissions from machinery (e.g., delivery vehicles, construction plant) and dust. Mitigation measures are proposed and include ensuring construction vehicles are serviced at regular intervals and during windy conditions have a water tanker. However, direct impacts on residents were deemed to be low given the proposal surrounds. Climate Change Climatic impacts were deemed to be minor given the nature and scale of the proposed activity. Greenhouse gas emissions associated with the proposal would include direct emissions from the operation of machinery and indirect emissions associated with the energy embodied in the materials used. Biodiversity No threatened species, populations, endangered ecological communities or their habitats listed under the Biodiversity Conservation Act 2016 (NSW) or the Environment Protection and Biodiversity Conservation Act 1999 (CTH) will be significantly affected by the proposal. Similarly, connectivity and habitat fragmentation are not envisaged. The works proposed seek to extend an existing road network and are contained within the road reserve. The vegetation proposed to be removed as part of the relevant works are not anticipated to create additional impacts given the already disturbed nature of the environment. Vegetation and habitat impacts are expected to be non-significant and will affect existing, scattered and fragmented roadside vegetation with low habitat value and interconnectivity significance. Lighting and Energy The operation of the use demands energy and lighting and other systems. This can have an impact on overall energy consumption and introduce potential lighting impact on sensitive receivers due to the placement of street lights in places where they were not before. Renewable energy sources are proposed to be explored for energy and street light provisions where appropriate. Further, vizor are to be used for traffic lights proposed hence that lighting impacts do not deflect to sensitive receivers. Noise and vibration Noise and vibration generation levels were found likely to exceed noise management levels during those times that operations are closest to businesses. Recommendation was issued to ensure reasonable and feasible construction noise mitigation. The main vibration generating activity with potential to affect nearby uses is the vibratory equipment. Monitoring was recommended to be undertaken in response to vibration related complaints. The upgraded road network would result in similar noise levels to the existing environment once the relevant works are completed.

Heritage Lot 101 in DP1143373 and Lot 162 in DP1087243 are identified as containing a heritage items (I105 and I104) with local significance. Niche Environment and Heritage provided a Statement of Heritage Impact (SOHI) to overview the proposal against the heritage significance of the site with recommendations. The works are to be conducted in accordance with the recommendations of the report. Lot 301 DP1143646 (440 Camden Valley Way) is listed as potentially having an Aboriginal heritage item (refer to Appendix D). Following the OEH's AHIP Register, it is noted that an approval to destroy has been issued for the Aboriginal heritage site (AHIP No. C0002506 dated 3/3/2017). Works relating to the extension of Liz Kernohan Drive will pass close to this area, however, given the existing approval to destroy, as well as the existing disturbed nature of the works site, the risk of disturbance of further culturally significant items is considered low. Landscape Character and Visual Impacts The proposed works will require the removal of approximately 98 trees including non-mature trees, exotic and weed species (overgrown African Olives) from the road reserves of Camden Valley Way and Kirkham Lane, and the land to the east of Liz Kernohan Drive extension. Amendments have been made to the design to include a retaining wall on the northern side of Camden Valley Way to retain some of the mature Liquid Amber trees in the vicinity of the proposed works. No vegetation removal is proposed from the north-east stretch of Camden Valley Way where the heritage items are located. Tree removal from the verges of Kirkham Lane is largely confined to the western side of the road with only three trees being removed from the eastern side and thereby minimising any impact on the adjoining heritage listed land. The proposal includes extensive landscaping to offset the amenity loss from the clearing. Existing weed species in the road reserve will be removed and replaced with native plantings as part of the proposed landscaping. Once established the proposed plantings will enhance the streetscape, provide pedestrian amenity and create visual buffers to sensitive areas, resulting in an overall improvement in the visual environment and ecological outcomes. While a low to moderate change in the visual environment along the streetscape is expected from the proposed clearing, these are mostly transient views experienced by the road users. Therefore, the amenity loss from the vegetation removal is not considered to have an unacceptable level of impact when balanced against the benefits of the proposed road works. Socio-Economic Impacts Potential traffic disruption is envisaged on Camden Valley Ways and the local road network of Hilder Street, Kirkham Lane and Liz Kernohan Drive during the relevant works. Including restrictions on movement which can cause inconvenience for road users. Traffic management practices are recommended to ensure flows are adequately maintained at critical times. It was not envisaged that business operations will be significantly affected by the activity. Waste Minimisation and Management The project is not expected to generate large quantities of waste materials. Any non-reusable fill from excavated areas will be transferred to a registered waste management facility for disposal. All suitable road-base waste will be transported to a recycling facility for potential reuse. Where possible, any green waste generated will be reused for landscaping works associated with the project.

Justification and conclusion The benefits derived from proceeding with the proposal will outweigh the potential short-term inconveniences. Underground Infrastructure The proposed development plans indicated the location of underground services comprised of reticulated water, sewer, and stormwater infrastructure. However, the development plans do not indicate the removal of underground infrastructure as part of the activity. It is recommended that consent be sought from the relevant public utility authority if utility adjustment is requirement as part of the proposed activity.

Location of Works

Figure 2: Site Plan (MetroMap, 2023)

The Camden Valley Way / Hilder Street intersection is currently configured as a ‘seagull’. Based on an analysis of this intersection turning right from Camden Valley Way into Hilder Street in the morning peak is difficult. Liz Kernohan Drive is designed to extend northwards from its current terminus and intersect with Camden Valley Way and Kirkham Lane. Currently the west-bound carriageway of Camden Valley Way at this intersection includes a right turning lane into Kirkham Lane. No left turning or right turning lanes into or out of Kirkham Lane currently exist. Kirkham Lane is a two-way road which takes on rural road type qualities in design and appearance. Pursuant to the Camden Local Environmental Plan 2010, the site of the activity is located primarily within zone SP2 Infrastructure (Classified Road). Where the road widening and ancillary works extend beyond the existing road reserve boundary, these areas comprise land in zone RE1 Public Recreation (south of Camden Valley Way) and RU1 Primary Production and R5 Large Lot Residential (north of Camden Valley Way). Figure 3 provides the zoning context of the proposed road upgrades.

THE PROJECT 4.1

PROJECT OBJECTIVES

The objectives of the proposal are: •

To improve traffic efficiency during peak periods

•

To improve safety for motorists, cyclists and pedestrians

•

To ensure quality urban design outcomes

•

To ensure good environmental outcomes

4.2

BACKGROUND

The Camden Local Government Area (LGA) is undergoing strong population growth (highest growth rate in Australia based on ABS statics for 2017) with a projected target of 300,000 people by 2040. With population growth, comes greater demand on infrastructure including the road network. With new residential subdivisions coming online and traffic generating land uses attracting greater activity (i.e., local schools and playing fields experiencing increasing numbers), the road network is approaching capacity levels. Assessments by the Roads & Maritime Services (RMS) and Council indicate that the road network in this location requires upgrading to maintain safe and efficient traffic flow. Traffic modelling conducted for the proposal indicates that the intersection is currently performing but will continue to deteriorate unless an upgrade is implemented. Improvements to the Camden Road network have been identified and improved connectivity is a key driver of local economic opportunity. The intersection upgrade of Camden Valley Way, Kirkham Lane and Liz Kernohan Drive will assist with traffic flows into recently completed residential subdivisions to the south. It will reduce travel times and the number of vehicles currently using local roads. The proposed roundabout at the intersection of Camden Valley Road and Hilder Street is also a result of increased volumes in this location to access Kirkham Park and Elderslie High School and will create a safer road environment which will function more efficiently and effectively. It is considered both projects will have a positive outcome on the manner in which the traffic network functions, reduce travel times and create safer road environments. 4.3

NSW STATE PRIORITIES

In 2015, the NSW Premier announced a new suite of “State Priorities” targeting growth and economic development (NSW Government 2015). Under the banner of “Building Infrastructure”, improving road travel reliability was listed as a key priority. This includes ensuring journey times on key roads continues to improve to enable businesses and the community to move around with greater ease and boosting productivity. To do this, the State Government are committed to making better use of existing road infrastructure. The primary aim of the project is to provide increased capacity through the two identified intersections which will reduce traffic congestion and better accommodate predicted volume increases. The project will assist in facilitating the State Government’s growth and economic goals to make better use of existing infrastructure.

REGIONAL AND LOCAL PLANNING CONSIDERATIONS

GREATER SYDNEY REGION PLAN The Greater Sydney Region Plan A Metropolis of Three Cities contains objectives for the provision of infrastructure greater opportunities for learning, labour participation, industry growth and development, and access to housing and services across Greater Sydney and to facilitate a functional “30-minute city”. The proposed activity is consistent with the objectives of the Greater Sydney Region Plan and is aligned with current and forecast growth in the Camden-Campbelltown-Macarthur sub-region. The proposed road upgrades will result in an improved safer transport network benefiting the movement of local and regional traffic. The proposal will enhance economic development in southwest Sydney by facilitating faster travel times. It will also facilitate a better way of life for commuters by reducing times and creating a safer road network. On this basis, the proposal is considered to be consistent with the objectives of the Region Plan. FUTURE TRANSPORT Future Transport 2056, which incorporates the Greater Sydney Services and Infrastructure Plan presents the 40-year vision for the delivery of world-class public transport, roads and freight network to the State and the Sydney Region. The Plan also identifies planned and co-ordinated actions required to address current challenges and develop a more integrated transport system. Greater Sydney, including the Camden LGA faces increasing congestion on arterial and local roads, particularly during peak periods. Easing congestion is a key objective of the Plan and it specifically outlines what actions are required to improve infrastructure services. It is considered the proposed upgrades are consistent with the Plan by increasing capacity, improving safety and reducing travel times for the residents of south-western Sydney. PROPOSAL OBJECTIVE The objectives of the proposal are: • • • • 4.5

To improve traffic efficiency during peak periods. To improve safety for motorists, cyclists and pedestrians. To ensure quality urban design outcomes. To ensure good environmental outcomes. NEED FOR THE ACTIVITY

To provide increased capacity through the two identified intersections which will reduce traffic congestion and better accommodate predicted volume increases. The project will assist in facilitating the State Government’s growth and economic goals to make better use of existing infrastructure. The project is informed by a traffic advice undertaken by Seca Solution in January 2018, attached as Appendix C. Traffic counts were undertaken during typical peak hours on weekdays as part of this study. The intersections were modelled using Sidra Intersection 7 to determine the capacity required to cater for the future growth and the changes in the traffic flows from the extension of Liz Kernohan Drive to Camden Valley Way. The modelling was based on the forecast flows for 2036 future scenario obtained from Council’s Strategic Traffic Model developed by TDG in 2015.

17/065 | Revised REF: Camden Valley Way Road Widening Works

Page | 16

SIDRA modelling considered the following scenarios in the morning and afternoon peak periods in 2036: • Single lane roundabout at Camden Valley Way/Hilder Street • Dual lane roundabout at Camden Valley Way/Hilder Street intersection as a dual lane • Traffic control signals at Camden Valley Way/Kirkham Lane and Liz Kernohan Drive intersection The modelling results indicated that the proposed works will allow Camden Calley Way/Hilder Street intersection will perform at Level of Service (LoS) A in both the scenarios. The proposal has adopted the dual lane roundabout as shown in Figure 5. An overall performance of LoS D is predicted for the signalised intersection at Camden Valley Way/Kirkham Lane and Liz Kernohan Drive intersection. An increase in queues and delays is expected at the latter beyond 2036; however, the study considers it acceptable given the 20-year design life for a project of this scale. Overall, the modelling results indicate the proposed upgrade works are required to accommodate the anticipated land use changes and growth and enable the intersections to operate at an acceptable level of service. 4.6

ALTERNATIVES CONSIDERED

Options were developed to specifically address the identified need and to have regard to the constraints imposed by the existing road alignments. The width of the existing road reserves, a need to avoid unnecessary land acquisition and traffic flows / volumes were also factored in. The process of option selection comprised a two-stage process: 1.

A consideration of whether the project in any configuration could be justified. This is an evaluation of the ‘do nothing’ option.

An evaluation of intersection improvement options by reference to agreed assessment criteria.

The following potential upgrade options have been assessed: •

Roundabouts at both intersections.

•

Traffic lights at both intersections.

•

Single and dual lane options at Hilder Street and Camden Valley Way intersection.

•

Do nothing option for the intersection of Hilder Street and Camden Valley Way and traffic lights at Liz Kernohan Drive.

RMS historical traffic data for Camden Valley Way indicates an average annual growth rate of 1.37%. Given the areas future residential and employment growth, and expansion of Narellan Town Centre, a conservative estimate of 2% (compound) annual growth is considered more appropriate for future traffic volume estimates which has been used in this assessment. Each option was assessed by reference to the following questions: •

How safe is the option?

•

How well does the option reduce congestion and delays?

•

How would the option affect access to the local area?

•

What impact does the option have on the environment?

•

Does the option represent value for money?

Page | 17

Ultimately, based on the analysis of the various options it was decided that the signalisation of the intersection of Camden Valley Way, Kirkham Lane and Liz Kernohan Drive, and the installation of a roundabout at the corner of Camden Valley Way and Hilder Street was the preferred approach. Refer to the attached traffic advice in Appendix C for details. 4.7

Detailed proposal designs plans are provided in Appendix A. Camden Valley Way will be widened through this section to two lanes in both directions. It is envisaged that works associated with the upgrades will be undertaken separately thus reducing the potential impacts on traffic flows. Further, laydown areas for construction are proposed as part of the relevant works. These will be located within Lot 1 DP 914674 and Lot 301 DP 1143646. However, as details of these works have not been provided, this assessment considers the use of this site for the temporary storage of materials, equipment, machinery etc. and includes recommendations to minimise impacts from the use of these sites during construction. As exact details of the sheds, offices etc. have not been provided, it is assumed that these structures will be constructed under the provisions for exempt developments in State Environmental Planning Policy (Transport and Infrastructure). A further amendment to the REF will be required if the proposed scope of works is outside the standards for exempt developments. 4.8

4.9.4

Episodic Risks

Episodic risks such as bushfire, coastal hazard, flooding, extreme weather events can have minor impacts on the proposal and result in additional impacts on the environment in combination with the proposed activity. As part of the activity, a Construction Environment Management Plan is to be development to detail methods for mitigating episodic risks as well as construction method to reduce bushfire hazard risks. Materials The proposal would require the following materials (but not limited to): •

Stormwater drainage pipes.

•

Concrete for kerb, gutter and pits.

• •

Traffic signal posts and other accessories. Fill material (volumes to be established as part of construction management plan).

•

Ground cover (e.g., turf).

•

Trees.

•

Sediment and erosion control devices.

4.9.5

Traffic Management and Access

Traffic would be managed in accordance with the RMS Traffic Control at Worksites Manual and through an approved traffic management plan. To avoid major congestion, lane closures would largely occur during off-peak periods and in consultation with the local traffic commander. Further, a reduced speed limit will be in place for the duration of works. Prior notice and updates will be provided to motorists and other users via temporary roadside mobile signs located in strategic locations. 4.9.6

Ancillary Facilities

It is proposed to use parts of Lot 1 DP 914674 and Lot 301 DP 1143646 as the project’s storage and stockpiling area. However, detailed plans for the laydown areas have not been provided at this stage. It is anticipated that these details will be identified in the construction environmental management plan. These areas will only operate for the duration of construction. Full details of any associated structures in this location are not yet known, and it is assumed that they can be undertaken under the exempt development provisions. As noted previously a further assessment will be required if the scope of works exceed the provisions of exempt development pathway. To the extent practicable, any stockpiling should be established, operated and decommissioned in accordance with the recommended work practices contained in the Waste management guideline 2023 and the Transport Stockpile Site Management Guideline, and the requirements of ‘Managing Urban Stormwater: Soils and construction – Volume 1’ (the Blue Book). All works on Lot 1 DP914674 should maintain a minimum separation of 40m from the drainage line on the site 4.9.7

Public Utility Adjustment

Several utility infrastructure relocations, adjustments and / or protection will be required as part of the project. The available ground survey indicates that there are a significant number of services on both sides of Camden Valley Way and connecting side streets. For the Hilder Street roundabout project these include water and sewer, power poles and overhead power lines. One power pole will require removal as it is located within that area identified to accommodate the roundabout. The design and relocation of is to be in accordance with the requirements of the Energy Australia approval. Further, the proposed development plans do not indicate the removal of reticulated water, sewer, and stormwater infrastructure as part of the

17/065 | Revised REF: Camden Valley Way Road Widening Works

Page | 26

activity. It is recommended that consent be sought from the relevant public utility authority if utility adjustment is requirement as part of the proposed activity. Existing stormwater culverts and headwalls running under the surface of Camden Valley Way are also located on both approaches to the proposed roundabout - with the proposed increase in the width of the road in this section these will be extended and upgraded. Existing stormwater pits are located on either side of the Hilder Street / Camden Valley Way intersection. As part of this project these pits will become redundant. For the Camden Valley Way / Kirkham Lane / Liz Kernohan Drive intersection upgrade, the following infrastructure will require relocation or adjustment: •

Power poles in Kirkham Lane, Camden Valley Way

•

Water hydrants in Kirkham Lane, Camden Valley Way

•

Water meters and water stop valve on Camden Valley Way to be adjusted

•

Telecommunications pit on Camden Valley Way to be adjusted

•

Sewer stop valve on Kirkham Lane to be adjusted

Specific requirements regarding adjustment / protection of utilities would be confirmed prior to construction and in consultation with the relevant infrastructure provider. 4.10 PROPERTY ACQUISITION The Hilder Street / Camden Valley Way roundabout element of the project will require the following lands to be acquired: •

Approximately 4670m² of Lot 11 DP827115 to the north of Camden Valley Way to facilitate the construction of the roundabout and the road widening for the required upgrading of an existing stormwater culvert / headwall.

The Camden Valley Way / Kirkham Lane / Liz Kernohan Drive element of the project will require the following lands to be acquired: •

Approximately 5083m² of Lot 11 DP827115 on the northern side of Camden Valley Way.

•

Approximately 2310m² of Lot 101 DP1143373 on the northern side of Camden Valley Way.

•

Approximately 614m² of Lot 101 DP1143373 on the eastern side of Kirkham Lane.

•

Approximately 330m² of Lot 5 DP882365 on the eastern side of Kirkham Lane.

Land on the southern side of Camden Valley Way are Council owned and zoned as RE1 Public Recreation Land where the proposed road upgrade and widening works are permitted. 4.11 STATUTORY AND PLANNING FRAMEWORK The Act establishes the statutory framework for planning and environmental assessment in New South Wales. Implementation of the Act is the responsibility of the Minister for Planning, statutory authorities, and local councils.

17/065 | Revised REF: Camden Valley Way Road Widening Works

Page | 27

The Act contains distinct parts which impose requirements for planning approval: •

Part 4 generally provides for the control of local “development” that requires development consent from the local Council.

•

Part 5 provides for the control of “activities” that do not require development consent and are undertaken and/or approved by a determining authority.

The applicable approval process is generally determined by reference to the relevant environmental planning instruments and other controls. These include Local Environmental Plans (LEPs) and State Environmental Planning Policies (SEPPs). Pursuant to Section 3.28 of the Act there is a general presumption that a SEPP prevails over a LEP in the event of an inconsistency. The proposed activity comprises development permitted without consent under the provisions of State Environmental Planning Policy (Transport and Infrastructure) 2021 (the Transport and Infrastructure SEPP). The works to be undertaken as part of the proposed activity are deemed to comply with the relevant provisions of the Transport and Infrastructure SEPP. Chapter 2, Part 2.3, Division 17 dictates that development for the purpose of a road or road infrastructure facilities may be carried out by or on behalf of a public authority without consent on any land. The proposal is appropriately characterised as development for the purposes of a road. Its individual elements have no independent purpose. Provided the provisions of Division 5.2 (State significant infrastructure) of Chapter 5 of the Act are not triggered, the proposed activity can be assessed under the provisions of Division 5.1 of Part 5. It is also noted that the proposal is not located on land reserved under the National Parks and Wildlife Act 1974 and does not affect land or development regulated by State Environmental Planning Policy (Resilience and Hazards) 2021 or State Environmental Planning Policy (Planning Systems) 2021.

17/065 | Revised REF: Camden Valley Way Road Widening Works

PLANNING CONTEXT

The provisions of the Act govern development within New South Wales. The following provides an assessment of the Activity against the relevant statutory documents and concludes that Part 5 of the Act is the applicable governing instrument. 5.1 5.1.1

COMMONWEALTH LEGISLATION Environment Protection and Biodiversity Conservation Act 1999

The Environment Protection and Biodiversity Act 1999 (EPBC Act) is administered by the Federal Department of Sustainability, Environment, Water, Population and Communities (DSEWPAC). The nine matters of national environmental significance to which the EPBC Act applies includes: 1. 2. 3. 4. 5. 6. 7. 8. 9.

World heritage sites. National heritage places. Wetlands of international importance. Nationally threatened species and ecological communities. Migratory species. Commonwealth marine areas. The Great Barrier Reef Marine Park. Nuclear actions. A water resource in relation to coal seam gas development and large coal mining development.

The proposed activity is considered an ‘action’ under Section 523 of the EPBC Act that aims to protect and manage matters of national environmental significance from actions that are likely to have a significant impact. The EPBC Act lists criteria that are used to determine whether or not an action is likely to have a significant effect on matters of national environmental significance. An action may be referred to the Department of Agriculture, Water, and the Environment for assessment to determine whether the likely environmental impacts are such that should be assessed under the EPBC Act. Should the Minister of the Department of Agriculture, Water and the Environment decide the proposed action requires approval, the proposed action is called a ‘controlled action’ and is subject to a formal assessment and approval process. In reviewing the Department of Agriculture, Water and the Environment Protected Matters Search Too on 27 June 2023, incorporating the entire area of the subject site. The search result noted nil species being within the minimum 10km search locality, refer to Appendix F. Overall, it is considered that no further action is required under the EPBC Act. 5.2 5.2.1

NSW LEGISLATION Environmental Planning and Assessment Act 1979

The Act provides the legislative requirements and processes for any development within NSW. Any development in NSW is determined in accordance with the provisions of Part 4 or Part 5 of the Act. Where an environmental planning instrument provides that specified development may be carried out without the need for development consent, a proponent may carry the development out on land to which the provision applies in accordance with that instrument.

17/065 | Revised REF: Camden Valley Way Road Widening Works

Page | 29

This REF provides an assessment of the proposed works against the relevant statutory documents and demonstrates that Part 5 of the Act is the appropriate approval process. Under Section 5.1 of the Act, the proposed development is defined as ‘carrying out of a work’ and is referred to as an ‘activity’, as such; the proposal will be referred to as ‘the activity’ in this report. As Council is the proponent, the works are to be assessed as ‘development permissible without consent’ under Part 5 of the Act. Accordingly, Council must satisfy Sections 5.5, 5.6 and 5.7 of that Act by examining to the fullest extent possible all matters which are likely to affect the environment. This REF is intended to assist, and ensure Councils' compliance, with the Act including Sections 5.5, 5.6 and 5.7 and the requirements of section 171 of the EP&A Regulation 2021. Environmental Planning Instruments made under the Act may also be relevant and are addressed below. 5.2.2

Environmental Planning and Assessment Regulation 2021:

Section 171 of the Environmental Planning and Assessment Regulation 2021 (Regulation) details the factors which must be taken into account when considering the likely impacts of an activity to be carried out under Part 5 of the Act and is addressed in Section 5 of this REF. 5.2.3

Biodiversity Conservation Act 2016

The purpose of the Biodiversity Conservation Act 2016 is to maintain a healthy, productive, and resilient environment for the greatest well-being of the community, now and into the future, consistent with the principles of ecologically sustainable development (described in Section 6(2) of the Protection of the Environment Administration Act 1991). An activity under Part 5 that is ‘likely to significantly affect threatened species’ is regulated under the Biodiversity Conservation Act 2016 and requires the preparation of a biodiversity development assessment report (BDAR) or species impact statement (SIS) before it can be determined and proceed. In accordance with Section 7.2(1) of the Biodiversity Conservation Act 2016, an activity is likely to significantly affect threatened species if: (a) (b) (c)

it is likely to significantly affect threatened species or ecological communities, or their habitats, according to the test in section 7.3, or the development exceeds the biodiversity offsets scheme threshold if the biodiversity offsets scheme applies to the impacts of the development on biodiversity values, or it is carried out in a declared area of outstanding biodiversity value.

The biodiversity offsets scheme does not apply to development under Part 5 (Section 7.2(2)). Nevertheless, a search of the NSW Government Biodiversity Values Map and Threshold Tool was undertaken on 27 June 2023. Mapped biodiversity value areas identified directly adjacent to the site of the activity (see Figure 9). It is noted, however, that the Biodiversity Values Map is only relevant to determining whether the Biodiversity Offset Scheme threshold has been exceeded, which does not apply for Part 5 development.

17/065 | Revised REF: Camden Valley Way Road Widening Works

Page | 30

Figure 9: Biodiversity Values Map and Threshold Tool (NSW Government, 2023)

An assessment under Section 7.3 has been completed to determine whether the proposed activity is likely to significantly affect threatened species, or ecological communities, or their habitats as outlined within Table 2 below. A search of the Environment and Heritage Bionet Atlas for recorded endangered, threatened and vulnerable species on 11 September 2023 identified 29 fauna species and 7 flora species within a 5km radius of the subject site. There are no recorded observations within or directly adjacent to the site of the works, though many of the species recorded could potentially occupy or be present in the area. Table 2: Part 7 Assessment SECTION

PROVISION

ASSESSMENT

1 (a)

(a) In the case of a threatened species, whether the proposed development or activity is likely to have an adverse effect on the life cycle of the species such that a viable local population of the species is likely to be placed at risk of extinction.

As per the Bionet Atlas of NSW Wildlife map, the works are not within proximity to threatened species and habitats. Whilst it is noted that the activity will result in removal of vegetation within the transport corridor, the removal of these trees within a disturbed landform are not anticipated to negatively impact on the locality.

1(b)

(b) In the case of an endangered ecological community or critically endangered ecological community, whether the proposed development or activity—

There are no endangered species identified on or near the location of the proposed activity. As noted above, the removal of trees within a disturbed landform is not considered to negatively impact on the locality.

The proposed activity is not identified as being near to a declared area of outstanding biodiversity value.

1(e)

(e)

Whether the proposed development or activity is or is part of a key threatening process or is likely to increase the impact of a key threatening process.

The proposed activity is not a key threatening process, it is unlikely to threaten the survival, abundance or evolutionary development of a native species or ecological community within the locality.

5.2.4

Contaminated Land Management Act 1997

The Contaminated Land Management Act 1997 (CLM Act) establishes a process for investigating and (where appropriate) remediating land that the EPA considers to be contaminated significantly enough to require regulation under Division 2 of Part 3. Further assessment or remediation under the CLM Act is not considered necessary in this regard. The activity area has not been declared as significantly contaminated under the CLM Act. Should suspected contaminants be identified on the site, an assessment will be carried out to determine if notification of the contamination under Section 60 of the CLM Act to the EPA is required. Any required remediation would be carried out in accordance with the CLM Act. The EPA database did not identify any order issued over the land under the Act. 5.2.5

Heritage Act 1977

The Heritage Act 1977 protects Non-Indigenous heritage and is administered by the NSW Heritage Office. Under Section 139 of the Act, an excavation permit must be obtained for the excavation or disturbance of a relic unless an exemption applies. Following a review of the State Heritage register on 27 June 2023, it is noted that the proposed activity area does not contain heritage items or places of State significance within a 500-metre radius. The area of activity is adjacent to Lot 101 in DP1143373 165 and Lot 162 in DP1087243 which are mapped as containing items of local heritage significance listed in the Camden Local Environmental Plan 2010 (reference: item no I105 Yamba and item no I104 Rheinbergers Hill). Niche Environment and Heritage were engaged to prepare a Statement of Heritage Impact (SOHI) to assess the heritage

17/065 | Revised REF: Camden Valley Way Road Widening Works

Page | 32

impacts of the proposed activity. The finding of the report provided the following conclusions on heritage impacts. • • • •

The subject area is not considered to have its own heritage value and the heritage items within the locality is unlikely to be impacted by the proposed works. There will be some reduction in curtilage for both items, and some removal of nonsignificant fencing and vegetation from along Camden Valley Way’s road reserve. There is the possibility of potential physical impacts to the southern structure within the ‘Yamba’ heritage item, but these can be avoided. The proposed works will modify the visual landscape in and around the subject area, but this is unlikely to cause negative impacts to the heritage value of nearby items or the subject area.

Given the above findings, the proposed works are deemed to pose an acceptable risk to the heritage value of the subject area and the identified heritage items and that the work proceed with caution. It is recommended that the proposed works are carried out following the recommendation of the SOHI. The SOHI forms part of this REF and is included in Appendix B. 5.2.6

Mine Subsidence Compensation Act 2017

The Mine Subsidence Compensation Act 2017 aims to regulate development in areas that were previously undermined. The site of the proposed activity is not within a Mine Subsidence District and is not subject to the provisions of this Act. 5.2.7

National Parks and Wildlife Act 1974 (NPW ACT)

The NPW Act regulates the control and management of all national parks, historic sites, nature reserves, and Aboriginal areas (among others). The aim of the Act is to conserve the natural and cultural heritage of NSW. Where works will disturb Aboriginal objects, an Aboriginal Heritage Impact Permit (AHIP) is required. The harming or desecrating of Aboriginal objects or places is an offence under Section 86 of the National Parks and Wildlife Act 1979. Under Section 90, an Aboriginal heritage impact permit may be issued in relation to a specified Aboriginal object, Aboriginal place, land, activity or person or specified types or classes of Aboriginal objects, Aboriginal places, land, activities or persons. As identified above, a search of the NSW National Parks and Wildlife’s Aboriginal Heritage and Information Management Services (AHIMS) database was undertaken 27 June 2023. The search revealed that potential Aboriginal sites are present within a 500-metre radius of the proposed activity area (see Figure 12).

17/065 | Revised REF: Camden Valley Way Road Widening Works

Page | 33

Figure 12: Approximate Location of Aboriginal Sites (AHIMS Web Services, 2023)

It has been confirmed that an approval to destroy has been issued for this item (AHIP No. C0002506 dated 3/3/2017). Given the proposed activity footprint, impacts are not envisaged on any further sites of Aboriginal cultural significance and the disturbance of culturally significant items is not expected. Nonetheless, standard precautionary measures are to be implemented during works to ensure regulatory procedures are followed in the event of unexpected finds, that works in the area cease, authorities be notified and further directions be obtained before works recommence. 5.2.8

Protection of the Environment Operations Act 1997

The NSW Protection of the Environment Operations Act 1997 (POEO Act) aims to protect and reduce degradation of the environment from development activities. The POEO Act examines issues such as air and water pollution, waste management and noise. The POEO Act also prescribes, “scheduled activities” in which a licence must be obtained from the Office of Environment and Heritage (OEH). The proposed activity is not identified as a Scheduled Activity under Schedule 1 of the POEO Act and therefore an Environment Protection Licence is not required for the proposed works. 5.2.9

Roads Act 1993

The Roads Act 1993 (Roads Act) provides for the classification of roads. It also provides for the declaration of Roads and Maritime and other public authorities as roads authorities for both classified and unclassified roads. It also regulates the carrying out of various activities in, on and over public roads. Consent to carry out works on an unclassified road is not required as per Schedule 2 Clause 5(1) of the Roads Act. However, a Road Occupancy Permit would need to be obtained as necessary prior to construction commencing.

17/065 | Revised REF: Camden Valley Way Road Widening Works

Page | 34

5.2.10 Rural Fires Act 1997 In accordance with Section 91 of the Act and the NSW Rural Fires Act 1997 Section 100B, a bushfire authority must be obtained before developing bushfire prone land for a subdivision of bush fire prone land that could lawfully be used for residential or rural residential purposes, or development of bushfire prone land for a special fire protection purpose. The subject site is identified as bush fire prone land. Despite this, the proposal is not that of subdivision or special fire protection purposes as defined in the Regulations. Therefore, a bushfire authority is not required as part of the proposal. As the proposal is development on bush fire prone land, the Planning for Bushfire Protection 2019 (PBP) will be applicable. As part of the Landscape Master Plan, NBRS has made design considerations to account for the bushfire categorisation. 5.2.11 Water Management Act 2000 The Water Management Act 2000 (WM Act) provides for the sustainable and integrated management of the State’s water resources for the benefit of both present and future generations. Section 91E of the Act establishes an approval regime for controlled activities within waterfront land. However, Clause 41 of the Water Management (General) Regulation 2018 provides an exemption for public authorities in relation to all controlled activities on waterfront land. Therefore, approval under the WM Act is not required. 5.3 5.3.1

ENVIRONMENTAL PLANNING INSTRUMENTS State Environmental Planning Policy (Transport and Infrastructure) 2021

State Environmental Planning Policy (Transport and Infrastructure) 2021 (the Transport and Infrastructure SEPP) aims to facilitate the effective delivery of infrastructure and educational facilities across the State. The works to be undertaken as part of the proposed activity are deemed to comply with the relevant provisions of the Transport and Infrastructure SEPP. Chapter 2, Part 2.3, Division 17 dictates that development for the purpose of a road or road infrastructure facilities may be carried out by or on behalf of a public authority without consent on any land. As exact details of the sheds, offices etc. on the construction compounds proposed on Lot 1 DP 914674 and Lot 301 DP 1143646 have not been provided, it is assumed that these structures will be constructed under the provisions for exempt developments in State Environmental Planning Policy (Transport and Infrastructure) 2021. A further amendment to the REF will be required if the proposed scope of works is outside the standards for exempt developments. 5.3.2

Camden Local Environmental Plan 2010

The Camden Local Environmental Plan 2010 (LEP) is the relevant local planning instrument applicable to the site of the proposed activity with the majority of works proposed within zone SP2 Infrastructure (Classified Road). Where the road widening and ancillary works extend beyond the existing road reserve boundary, these areas comprise land in zone RE1 Public Recreation (south of Camden Valley Way) and RU1 Primary Production and R5 Large Lot Residential (north of Camden Valley Way). Although the proposed activity does not rely on the LEP for permissibility, it is noted that “roads” comprise development permitted with consent in each of the applicable LEP land use zones over which the activity will take place. The road widening and upgrade works are also consistent with the relevant objectives of the above zones.

17/065 | Revised REF: Camden Valley Way Road Widening Works

Page | 35

Other relevant provisions of the LEP applicable to the proposal are the two heritage items of local significance listed in Schedule 5 (item no I105 Yamba and item no I104 Rheinbergers Hill). Heritage impacts are addressed in this REF and a Statement of Heritage Impact is submitted in support of the proposal (see Appendix B). 5.4

CONCLUSION

The proposed activity is permitted as development without consent under the State Environmental Planning Policy (Transport and Infrastructure) 2021. It is concluded that the activity is permissible without consent and can be carried out on behalf of Camden Council under Part 5 of the Act. No further approvals are required as part of the proposal under the provisions of the Act.

CONSIDERATION OF ENVIRONMENTAL FACTORS 6.1

DUTY TO CONSIDER ENVIRONMENTAL IMPACT

Section 5.5 of the Act requires the determining authority to examine and consider to the fullest extent possible all matters affecting or likely to affect the environment by reason of that activity. The regulatory requirements for environmental impact assessment of activities are specified in Section 5.6 of the Act. This section identifies the environmental impact assessment functions of a determining authority in accordance with the EP&A Regulations. Section 171 of the Regulation requires the determining authority to consider the environmental factors specified in the environmental factors guidelines that apply to the activity when considering likely impacts on the environment. The “Guidelines for Division 5.1 Assessments” published by the Department of Planning and Environment which has been applied to the assessment of the proposed activity in accordance with the section 171 requirements. The guidelines include reference to the environmental factors for consideration in section 171(2) of the Regulation. These factors are addressed in Table 3. Table 3: Consideration of Environmental Factors (Section 171(2) of the Regulation) SECTION 171(2) FACTOR (a) the environmental impact on the community,

COMMENTS

IMPACT

No significant environmental impacts are expected.

Minor / Short Term

There will be some minor loss of vegetation and some surface disturbance. Vegetation and surface impacts will be limited and contained to not exceed any greater disturbance than necessary to carry out the works. There is potential for noise, dust and sediment/erosion impacts in the immediate surrounds during the activity. These will be controlled and regulated to avoid or minimise unreasonable impacts.

(b) the transformation of the locality,

The activity will involve excavation and a minor level of vegetation clearing to achieve the required road width. The works take place on Council road reserve in an already moderately disturbed environment.

Minor

Some minor but insignificant impact on the ecosystems of the locality is expected. These impacts are primarily in a moderately disturbed environment. The minor impacts expected will not result in any significant disturbance or irreversible damage to the ecosystems of the locality.

Minor / ShortTerm

(d) reduction of the aesthetic, recreational, scientific or other environmental quality or value of the locality,

Significant impacts expected are not envisaged. The proposed activity and construction will have a minor aesthetic impact given the existing disturbed land use. New impacts can be mitigated by landscaping comprised of soft and hard.

COMMUNITY ENGAGEMENT

In line with the community participation objectives detailed within the Camden Community Participation Plan 2021, Council is to inform and consult with the public on the proposed activity as soon as practicable. A Community Participation Plan (CCP) will be developed and published on Council’s website prior to the commencement of construction. The CCP will identify and notify key stakeholders, both internal and external, providing regular update on project progress. Communication channels will include: • • •

6.4

Direct outreach: Letter mail-outs to adjacent landowners and site notices Digital platforms: Regular project updates on the Council website, including project details, timelines, completed work, relevant documentation and announcements. Community contact: A dedicated project mailbox for community members and stakeholders to provide feedback and inquiries. ABORIGINAL COMMUNITY INVOLVEMENT

An Aboriginal Heritage Information Management System (AHIMS) search was undertaken which identified a potential Aboriginal site in the project area (Lot 301 DP1143646 (158 Camden Valley Way) – Aboriginal sites are recorded in or near the above location). Following the OEH's AHIP Register, it can be confirmed that an approval to destroy has been issued for this item (AHIP No. C0002506 dated 3/3/2017), refer to Appendix G. Works relating to the extension of Liz Kernohan Drive will pass close to this area, however, given the existing approval to destroy, as well as the existing disturbed nature of the works site, the risk of disturbance of further culturally significant items is considered low. Whilst it is considered the risk is low, it is nonetheless recommended that prior to disturbance of the area and its surrounds, a suitably qualified professional undertake a physical assessment of the site to determine if any items exist and if found appropriate action taken in consultation with the local Aboriginal community. 6.5

GOVERNMENT AGENCY AND STAKEHOLDER INVOLVEMENT

No government authorities have been consulted on issues relating to the proposed development in the preparation of this REF. Consultation is to be carried out with government agencies and other key stakeholders where required. This consultation will include: • •

A copy of the REF and design is made publicly available. Stakeholders informed prior to construction commencing.

It is envisaged there will also be on-going discussions prior to and during construction with Transport for NSW, local bus services, NSW Police, and other emergency service providers. 6.6

ONGOING OR FUTURE CONSULTATION

Camden Council is to continue to inform residents and stakeholders of the ongoing progress of the project in line with the Community. This will be carried out using methods such as the distribution of updates, emails to identified stakeholders, and updates on Council’s project website.

6.7 6.7.1

ABORIGINAL AND CULTURAL HERITAGE Existing Environment

Lot 301 DP1143646 (440 Camden Valley Way) is listed as potentially having an Aboriginal heritage item (refer to Appendix D). 6.7.2

Impact Assessment

The works associated with the project on this site are located along the immediate frontage of Camden Valley Way and in terms of disturbance of the ground is considered relatively minor. 6.7.3

Mitigation Measures

The following mitigation measures are recommended for aboriginal and cultural heritage management. 6.7.4

Recommendation 1:

Prior to work commencing, the actual location of the item is to be identified and if required a plan of management put in place to either protect it or to make an application with the Department of Planning and Environment for its removal. An AHIP will need to be obtained or the existing AHIP will need to be transferred to relevant person undertaking the works. It is recommended that prior to disturbance of the area and its surrounds, a suitably qualified professional undertake a physical assessment of the site to determine if any items exist and if found appropriate action taken in consultation with the local Aboriginal community. 6.7.5

Recommendation 2:

The Standard Management Procedure – Unexpected Heritage Items is to be employed during the construction phase of the activity. Unexpected finds

6.7.6

The Standard Management Procedure – Unexpected Heritage Items must be followed if a known or potential Aboriginal object(s), including skeletal remains, is found during construction. This would also involve consultation with local Aboriginal groups and the need to obtain an AHIP approval. Work may only re-commence once the requirements of that procedure have been satisfied.

Site Manager

Construction

Recommendation 3:

Works should cease and an appropriately qualified person, or OEH / Heritage Office, is to be consulted and advise on any management or mitigation measures that may be required to be implemented should Aboriginal or European heritage items or artefacts be unearthed during the works.

6.8 6.8.1

AIR QUALITY / CLIMATE / ENERGY Existing Environment

The current air quality of the area is considered to be comparable to that of a typical open periurban setting (relatively clean). However, a major source of air pollution for the local area is exhaust emissions from motor vehicles travelling along Camden Valley Way. Exhaust from these vehicles would include (but is not limited to) the release of greenhouse gases as well as the production of small, airborne particulates, leading to semi-ideal air quality. It is not envisaged that the project would change the existing mix or amount of traffic that utilises the road network in this location. As such, it is unlikely that a substantial change in existing longterm air quality would occur as a result of the upgrade. 6.8.2

Impact Assessment

Air quality impacts during the construction phase of the project would largely be from dust generated during earthworks, and exhaust fumes from machinery and vehicles idling at stop / go locations. Measures can be introduced to mitigate some of these impacts as outlined in the table below. 6.8.3

Mitigation Measures

The following recommendations are proposed to mitigate air quality, climate and energy impacts associated with the proposed activity. 6.8.4

Recommendation 1:

Pre-construction works, an Air Quality Management Plan (AQMP) is to be prepared and implemented as part of the CEMP to mitigate air quality impacts during construction. The AQMP will identify: •

Potential sources of air pollution (such as dust, vehicles transporting waste, plant and equipment) during construction;

•

Air quality management objectives consistent with the relevant published EPA and/or OEH guidelines;

•

Mitigation and suppression measures to be implemented, such as spraying or covering exposed surfaces, provision of vehicle clean down areas, covering of loads, street cleaning, use of dust screens, maintenance of plant in accordance with manufacturer's instructions;

•

Methods to manage work during strong winds or other adverse weather conditions;

•

A progressive rehabilitation strategy for exposed surfaces;

•

A monitoring program to assess compliance with the identified objectives, and developed in accordance with any relevant published EPA and/or OEH guidelines; and

•

Community notification and complaint handling procedures.

6.8.5

Recommendation 2:

Pre-construction works, all sensitive receivers likely to be affected are to be notified a minimum of five days prior to commencement of any work that may have an adverse impact on local air quality. The notification is to include details of the project construction period and construction hours; any recommended measures that can be implemented (e.g. window closure, staying indoors, etc.), contact information for project management staff; complaint and incident reporting; and how to obtain further information.

17/065 | Revised REF: Camden Valley Way Road Widening Works

Page | 42

6.8.6

Recommendation 3:

Pre-construction works, all personnel working on-site are to receive training to ensure awareness of requirements of the AQMP. 6.8.7

Recommendation 4:

During construction works, the adopted AQMP mitigation and suppression measures are to be implemented to protect local air quality when required. 6.9 6.9.1

BUSHFIRE Existing Environment

The proposed activity area contains mapped bushfire hazard buffer following the NSW Planning Portal mapping. 6.9.2

Impact Assessment

Bushfire hazard impacts are not envisaged for the proposed activity. The activity seeks to extend an existing road network and is not associated with the introduction of a new use. Further, the proposed activity area is located within the bushfire hazard buffer overlay and does not include high bushfire risk areas. 6.9.3

Mitigation Measures

Mitigation measures are not proposed as the activity is not associated with bushfire impacts. 6.10 FLORA AND FAUNA 6.10.1 Existing Environment The project area is largely disturbed and either urban, public open space or semi-rural in nature. Existing trees located along the road reserve and within private property fronting Kirkham Lane are either native vegetation regrowth, exotic plants or weed species. 6.10.2 Impact Assessment The extent of works proposed affects existing roadside vegetated areas with low habitat value and a low likelihood of containing endangered, threatened or vulnerable flora or significant habitat for fauna. It is noted that the proposed activity area is not mapped as containing biodiversity values following a review of the Biodiversity Values Map and Threshold Tool. Accordingly, it is considered that no further assessment is warranted and that the required removal of vegetation to facilitate the activity can be supported. If opportunities exist, it is suggested that a landscape replacement strategy is adopted. 6.10.3 Mitigation Measures The following recommendations are advised to minimise impacts on Flora and Fauna:

17/065 | Revised REF: Camden Valley Way Road Widening Works

Page | 43

6.10.4 Recommendation 1: During construction, the works are to be consistent with the Biodiversity Guidelines – Protecting and managing biodiversity on RTA projects, and any specific requirements of management arrangements would be implemented to manage environmental risks associated with weeds, pest species and pathogens. As a minimum this would include: •

Completion of a site weed assessment and, if necessary, based on the assessment outcomes, a weed management plan;

•

Implementation of appropriate weed control methods and weed disposal; and

•

Implementation of appropriate hygiene protocols where there are potential or known pathogen risks.

•

Preclearing surveys should be undertaken by a suitably qualified ecologist. Similarly, all tree removal must be supervised by a suitably qualified ecologist.

•

The construction laydown areas for the activity should be located away from the tree protection zone of the vegetation to be retained, with appropriate tree protection measures implemented (if required) to eliminate adverse impacts.

6.10.5 Recommendation 2: Compensatory plantings as per the Landscape Plan to offset the tree removal required for the development. 6.11 LANDSCAPE AND VISUAL IMPACT 6.11.1 Existing Environment The project area is located at the current interface between urban and rural land uses. It is relatively flat and has some tree coverage. Land to the north of Camden Valley Way and those adjoining Kirkham Lane are typically open rural lands previously used for grazing. Sites with local heritage significance are located on either side of the north- eastern stretch of Camden Valley Way. The verges of Camden Valley Way currently contain fragmented linear tree plantings within no significant biodiversity value. The affected area of Kirkham Lane has a row of trees with regrowth native vegetation and exotic vegetation which includes weed species on either side of the road reserve. 6.11.2 Impact Assessment The proposed works will require the removal of approximately 98 trees including non-mature trees, exotic and weed species (overgrown African Olives) from the road reserves of Camden Valley Way and Kirkham Lane, and the land to the east of Liz Kernohan Drive extension. Trees to be removed from Camden Valley Way reserve are largely located at the interface of agricultural and recreational lands. As such the existing visual buffer to the residential area will not be significantly impacted proposed clearing. Amendments have been made to the design to include a retaining wall on the northern side of Camden Valley Way to retain some of the mature Liquidamber Trees in the vicinity of the proposed works. No vegetation removal is proposed from the north-east stretch of Camden Valley Way where the heritage listed parcels are located. Tree removal from the verges of Kirkham Lane is largely confined to the western side of the road with only three trees being removed from the eastern side and thereby minimising any impact on the adjoining heritage listed land.

17/065 | Revised REF: Camden Valley Way Road Widening Works

Page | 44

Removal of seven trees from the land to the east of the proposed extension to Liz Kernohan Drive is anticipated to have a moderate level of impact on the outlook of the recreational reserve. However, this change in the visual environment will be mostly experienced by the road users as the closest residential development is more than 100m away from this location. The Landscape Plans prepared by Group GSA demonstrate extensive plantings along the roadways to establish green corridors with native plantings. A wide variety of native trees are included in the design to establish green corridors with screening vegetation to buffer heritage significant lands and residential developments. The Landscape Plans attached in Appendix H provide a detailed schedule of plantings and landscape treatments to the roundabout and intersection proposed as part of the development. As demonstrated in the Landscape Plan, the clearing required for the development is insignificant compared to the proposed tree plantings and landscaping. Some of these include: •

•

• •

Liquidambar Styraciflua along Camden Valley Way between the two intersections, and a mix of Pyrus Ussuriensis, Lophostemon confertus and Leptospermum continentale to the east of the four-way intersection to provide variety, visual interest and screening in the vicinity of future large lot residential developments. Kirkham Lane will be provided with a mix of native trees and screen plantings comprising Lophostemon confertus, Corymbia maculata, Eucalyptus sideroxylon, Leptospermum continentale etc. Hilder Street will be provided with Eucalyptus amplifolia on the eastern side. A variety of large street trees including Corymbia eximia and Angophora subvelutina are proposed along Liz Kernahan Drive, along with ground covers along the median.

Existing weed species in the road reserve will be removed and replaced with native plantings as part of the proposed landscaping. Once established the proposed plantings will enhance the streetscape, provide pedestrian amenity and create visual buffers to sensitive areas, resulting in an improved visual and environmental outcome. While a low to moderate change in the visual environment along the streetscape is expected from the proposed clearing, these are mostly transient views experienced by the road users. Therefore, the amenity loss from the vegetation removal is not considered to have an unacceptable level of impact when balanced against the benefits of the proposed road works. During construction, the project area and laydown areas will cause some visual impacts, however this will be short term and is considered acceptable with the recommended measures being adopted. 6.11.3 Mitigation Measures The following measures are proposed pre-construction and during construction to mitigate visual and landscape impacts. 6.11.4 Recommendation 1: During construction, project work sites, including construction areas and supporting facilities are to be managed to minimise visual impacts, including appropriate storage of equipment, parking, stockpile screening and arrangements for the storage and removal of rubbish and waste materials in a timely manner. If required, temporary site lighting will be installed and operated in accordance with AS4282:1997 Control of the Obtrusive Effect of Outdoor Lighting.

6.11.5 Recommendation 2: Pre-construction and during construction, a Landscape Management Plan to ensure cost effective and consistent management of landscape works is to be developed and implemented during construction. 6.12 HYDROLOGY, FLOODING AND WATER QUALITY 6.12.1 Existing Environment The project area is located in the Nepean River sub-catchment of the Hawkesbury Nepean catchment. There are watercourses in proximity to the project (Herbert Rivulet and Oxley Rivulet) and subsurface drainage is evident. It is noted that designs for Herbert Rivulet will be considered and developed outside the scope of this project. 6.12.2 Impact Assessment It is not envisaged that any changes to flows will have a significant impact on local flooding or drainage. As appropriate safeguard measures will be implemented during the construction phase of the project, it is anticipated that the activity will not have an unacceptable level of impact on the flow paths and existing hydrology of the locality. 6.12.3 Mitigation Measures The following mitigation measures are proposed for hydrology, flooding and water quality management. 6.12.4 Recommendation 1: Pre-construction and during construction, a Soil and Water Management Plan (SWMP) is to be prepared in accordance with the relevant standard and implemented as part of the Construction Environment Management Plan (CEMP) for water quality impacts by the Project Manager. The SWMP will identify all reasonably foreseeable risks relating to soil erosion and water pollution associated with undertaking the activity and describe how these risks will be managed and minimised during construction. This will include arrangements for managing pollution risks associated with spillage or contamination on the site, the laydown areas and the adjoining areas and monitoring during and post-construction. 6.12.5 Recommendation 2: Pre-construction and during construction, a site-specific Erosion and Sediment Control Plan (ESCP) is to be prepared and included in the SWMP and CEMP for water quality impacts by the Project Manager. The ESCP is to identify detailed measures and controls to be employed to minimise erosion and sediment control risks including, but not necessarily limited to runoff, diversion and drainage points. The ESCP will also include arrangements for managing wet weather events, including monitoring of potential high-risk events (such as storms) and specific controls and follow-up measures to be applied in the event of wet weather.

17/065 | Revised REF: Camden Valley Way Road Widening Works

Page | 46

6.12.6 Recommendation 3: Minimise risks to water quality during construction, consistent with any specific requirements of the approved SWMP, control measures implemented to minimise risks associated with erosion and sedimentation entry to drainage lines and waterways. That is to include, but not necessarily be limited to: Sediment management devices, such as sediment fencing, straw bales or sandbags; Measures to divert or capture and filter water prior to discharge, such as drainage channels and first flush systems; • Installation of measures at work entry and exit points to minimise movement of material onto adjoining roads, such as rumble grids or wheel wash bays; and Appropriate location and storage of construction materials, fuels and chemicals, including bunding where appropriate. The construction compound must maintain a minimum clearance of 40m from the drainage line on Lot 1 DP 914674, as indicated on the plans in Appendix I. • •

6.13 NOISE / VIBRATION 6.13.1 Existing Environment The existing environment includes noise and vibration generated from vehicle egress and ingress along Camden Valley Way. 6.13.2 Impact Assessment The proposed activity can generate noise and vibration levels which can exceed construction management levels during those times that operations are closest to businesses. Mitigation Measures Noise and Vibration Management Plan (NVMP) will be prepared for the activity. 6.13.3 Recommendation 1: Pre-construction, the Project Manager is to ensure that a Noise and Vibration Management Plan (NVMP) is prepared as part of the CEMP for construction noise. The NVMP will be prepared in accordance with the ICNG and will identify: • All potential significant noise and vibration generating activities associated with the activity; • Measures to be implemented during construction to minimise noise and vibration impacts, such as restrictions on working hours, staging, placement and operation of work compounds, parking and storage areas, temporary noise barriers, haul road maintenance, and controlling the location and use of vibration generating equipment; • Feasible and reasonable mitigation measures to be implemented; and • Arrangements for consultation with potentially affected neighbours and sensitive receivers, including notification and complaint handling procedures contingency measures to be implemented in the event of non-compliance with noise and vibration criteria. • Special consideration should be given to the amenity of the dwelling adjoining the western boundary of Lot 1 DP 914674 where the construction compound is proposed. Adequate noise mitigation measures should be implemented to minimise impact on this receiver.

17/065 | Revised REF: Camden Valley Way Road Widening Works

Page | 47

6.13.4 Recommendation 2: During construction, the majority of works are likely to be carried out during standard working hours (i.e., 7am – 6pm Monday to Friday, 8am –1pm Saturdays). The Site Manager is to ensure that any work that is performed outside normal work hours or on a Sunday or public holiday minimises noise impacts in accordance with Roads and Maritime’s Environmental Noise Management Manual Practice Note 7 – Roadworks Outside of Normal Working Hours and the ICNG. 6.13.5 Recommendation 3: During construction, the Site Manager is to ensure that construction personnel is made familiar with the potential for noise and vibration impacts upon local residents and encouraged to take all practical and reasonable measures to minimise noise during the course of their activities. 6.13.6 Recommendation 4: During construction and where practical, the Site Manager is to ensure that the layout and positioning of noise-producing plant and activities at each work site are located and orientated to minimise noise emission levels. 6.13.7 Recommendation 5: During construction and where practicable, the Site Manager is to ensure that equipment is selected to minimise noise emissions. Equipment is to be fitted with appropriate noise control equipment and be in good working order. 6.13.8 Recommendation 6: During construction and where practical/possible, the Site Manager is to ensure that non-beeper reversing movement alarms are used such as broadband (non-tonal) alarms or ambient noisesensing alarms. Work site layouts will be designed to reduce the need for reversing, potentially minimising the use of reversing beepers. 6.13.9 Recommendation 7: During construction, the Site Manager is to ensure that vehicles, plant and equipment are regularly inspected and maintained to avoid increased noise levels from rattling hatches, loose fittings etc. 6.13.10

Recommendation 8:

During construction, the Site Manager is to ensure that all vehicles, plant and equipment will be shut down when not in use. 6.13.11

Recommendation 9:

During construction, the recommended safe working distances for vibration intensive plant are to be considered during construction planning. Mitigation measures may be required where sensitive receivers are located closer to the construction work than the safe working distances.

6.14 TRAFFIC AND TRANSPORTATION 6.14.1 Existing Environment The traffic and transportation condition of the existing environment is comprised of light vehicle and truck egress and ingress via Camden Valley Way for east and west bound traffic. 6.14.2 Impact Assessment Construction of the project will generate light vehicle, truck and construction equipment movements to and from the site. The typical traffic generating activities would include construction staff travelling to and from site, delivery of plant, equipment and construction materials, and collection and disposal of waste not appropriate for reuse onsite. Parking for construction staff will be provided in a dedicated location identified as part of the construction management plan. Individual lane or full road closure may be required at times to undertake work. This may include the closure of some lanes, which is likely to affect the flow of traffic. Prior to construction, a Traffic Management Plan (TMP) for the project will be developed. The TMP will include the guidelines, general requirements and procedures to be used when activities or areas of work have a potential impact on existing traffic arrangements. As such, construction may have a moderate to high impact on traffic and network performance. 6.14.3 Public Transport Bus travel times may be impacted due to lane closures and associated project construction activities; however, services should remain open and operational. The bump on effect is that train connections will be impacted which will be an inconvenience to commuters. Unfortunately, this is largely unavoidable and challenging to manage. Potential options include minimising road closes etc. during peak hour traffic and including in the community communication package messages around commuters allowing additional travel times and an apology for the inconvenience caused. 6.14.4 Active Transport Pedestrian and cycle pathways within the immediate area will be partly closed during construction for safety reasons and upgrading. Where active transport routes and connections are temporarily removed or blocked due to the project, an alternative path will need to be provided. It is considered there is sufficient space in the existing road reserve and adjacent public spaces to accommodate temporary pedestrian / cycle paths during construction. As it may be difficult to provide cycle facilities with compliant standards (such as shared use paths) at all times during construction, a temporary signed cycle route may be an option. A temporary cycle detour (identified through signage and line-marking) may be used to facilitate this connection. Cyclists would need to negotiate the temporary path facilities and as such the existing paths should be maintained wherever possible. It is considered that the project will have a negligible impact / short term effect on the active transport network. Property Access Vehicle access to properties with frontages to the project sites will not be affected. During the construction phase, access for emergency vehicles will need to be provided and specific routes confirmed and detailed in the TMP. Other works may require partial closure of the intersections limiting access. It is recommended that these works be staged so access is maintained and completed outside of peak times or as night works where possible. It is considered that construction of the project will have minimal to no impact on property access and if so, it will be short-term.

17/065 | Revised REF: Camden Valley Way Road Widening Works

Page | 49

6.14.5 Operation: The completed upgrades will improve reliability of journey times, particularly during peak travel periods. The activity will reduce traffic congestion and delays by increasing the capacity of the intersections. The future operational performance of the intersections has been determined as good and will operate at a level of service where average delays per vehicle will be reduced. The upgrade will have a positive effect on traffic and network performance. 6.14.6 Road Safety The level of service and delays experienced at the identified intersections is likely to reduce the ‘stop-start’ travel conditions which will lead to improved road safety (improved traffic flows within a signalised controlled environment). On this basis, it is considered the road upgrade will have a positive impact on road safety once operational. 6.14.7 Public Transport It is understood that all bus routes and services within the locality will be retained. Once completed and operational, the improved road network is likely to have a positive effect on the public transport network. Active Transport Existing paths will largely be retained, and improved pedestrian crossings will be provided. It is considered that these upgrades will have a positive outcome on the active transport network once operational. 6.14.8 Mitigation Measures Safeguards and mitigation measures are to be implemented to minimise the impacts of the project. 6.14.9 Recommendation 1: Pre-construction, a TMP is to be prepared and implemented in accordance with the Roads and Maritime Traffic Control at Worksites Manual (Version 4), Australian Standard 1742.3 Manual of Uniform Traffic Control Devices, and instruction from the Transport Management Centre. 6.14.10

Recommendation 2:

Pre-construction and during construction, road users, local residents, pedestrians and cyclists are to be advised in advance of changes including the use of appropriate signage. 6.14.11

Recommendation 3:

During construction, Real-time information would be made available through temporary Variable Message Signs (VMS), and the media. 6.14.12

Recommendation 4:

During construction, materials are to be managed to minimise the number of haulage and delivery vehicles required on site. 6.14.13

Recommendation 4:

During construction, the designated site access points and haulage routes would be used.

17/065 | Revised REF: Camden Valley Way Road Widening Works

6.14.14

Recommendation 4:

Post construction affected areas are to be restored to a condition equivalent to that which existed prior to the commencement of the work. 6.15 SOILS AND GEOLOGY 6.15.1 Existing Environment The project area is described as being flat. The physiography of the soils is described as plain under woodland shrub understorey on alluvium lithology with soil types of Stratic Rudosol (ASC) and Alluvial (GSG). The site of the proposed works is not identified as containing potential acid sulfate soils. Groundwater is likely to be present given the surrounding watercourses. Limited sub-surface excavation will be required below the existing surface levels to clearly establish its depth and qualities. In the event that groundwater is encountered, a detailed geotechnical investigation will be undertaken and if warranted a management plan developed. 6.15.2 Impact Assessment It is not considered that the project, either during construction or once operational will not have an adverse impact on the area’s soils or geology. 6.15.3 Mitigation Measures The following mitigation measures are proposed for soil and geology. 6.15.4 Recommendation 1: Pre-construction, a Soil Management Plan (SMP) is to be prepared in accordance with the relevant standards and implemented as part of the CEMP to mitigate soil impacts. The SMP is to identify all reasonably foreseeable risks relating to subsurface impacts and pollution associated with undertaking the activity and describe how these risks will be managed and minimised during construction. This will include arrangements for managing pollution risks associated with spillage or soil contamination on the site and adjoining areas and monitoring during and post construction period. 6.15.5 Recommendation 2: During construction, appropriate environmental practices are to be adopted for washdowns and refuelling having regard to potential impacts on groundwater in addition to the implementation of general erosion, sediment and water quality control safeguards. During construction, where groundwater is intercepted during construction works, it will be managed to minimise potential adverse impacts in accordance with the RTA Technical Guideline: Environmental Management of Construction Site Dewatering. These may include, but not necessarily be limited to: • •

Options to collect and store groundwater to enable recharge of the water table (such as via grassed swales); and Where recharge is not appropriate or feasible, discharging groundwater to the surface water drainage system following suitable treatment to ensure discharged water is of an appropriate quality.

17/065 | Revised REF: Camden Valley Way Road Widening Works

Page | 51

Prior to any dewatering activities being carried out, an approval must first be obtained in accordance with section 92 of the WM Act. 6.15.6 Recommendation 3: During construction, the rehabilitation of disturbed areas are to be carried out progressively and in accordance with the following guidelines: • • •

Managing Urban Stormwater: Soils and Construction series; TfNSW Landscape Design Guideline; and RMS Roads and Maritime Guideline for Batter Stabilisation Using Vegetation.

6.16 RESOURCE USE AND WASTE MANAGEMENT 6.16.1 Existing Environment The project area encompasses an existing road network and pedestrian facilities which have minimum waste generation and resource use. Vegetation which has been identified to be removed will generate green waste, if unable to be reused in the landscape element of the project. 6.16.2 Impact Assessment Generators of waste are responsible for the correct classification of the waste they produce in accordance with the EPA Waste Classification Guidelines Part 1: Classifying waste (the Waste Classification Guidelines). A waste register is required to ensure that legislative requirements are met. The WARR Act provides a framework for considering resource management and is given effect by the NSW Waste Reduction and Purchasing Policy (WRAPP). Under the WRAPP Reporting Guidelines, agencies are required to give priority to buying materials with recycled content, when it is cost and performance competitive to do so (OEH, 2016). The project requires large volumes of fill being transported to and from the site. This can result in increased demand for natural soil resource if the development solely relies on fill transport from areas other than the development area. 6.16.3 Mitigation Measures Mitigation measures are proposed for resource use and waste management as follows: 6.16.4 Recommendation 1: Pre-construction and during construction, contractors are to be required to propose recycled-content materials where they are cost and performance competitive and are the environmental equivalent (or better) than non-recycled alternatives. Specific materials that are targeted for reuse or recycling in accordance with the Roads and Maritime Environmental Sustainability Strategy that are specifically relevant to this proposal. 6.16.5 Recommendation 2: Pre-construction, a Waste Management Plan (WMP) is to be prepared and implemented as part of the CEMP. It is to provide specific guidance on measures and controls to be implemented to support minimising the amount of waste produced and appropriately handling and disposing of unavoidable waste. It is to also address the importation of waste to the site for use in undertaking the project. The WMP will give effect to any management measures contained in any waste assessment carried out for the project and include, but not necessarily be limited to:

• • • • •

Measures to avoid and minimise waste associated with the project; Classification of wastes generated by the project and management options (re-use, recycle, stockpile, disposal); Classification of wastes received from off-site for use in the project and management options; and Procedures for storage, transport and disposal; The WMP will be prepared considering the Roads and Maritime Environmental Procedure – Management of Wastes on Roads and Maritime Services Land and relevant Roads and Maritime Waste fact sheets.

6.16.6 Recommendation 3: During construction, Waste is to be classified in accordance with the methods and specifications of the NSW EPA Waste Classification Guidelines 2014. 6.16.7 Recommendation 4: During construction, any trees to be removed shall be reused as mill-able timber wherever practicable. Other vegetated material from native species shall be mulched and re-used on-site for landscaping or rehabilitation purposes if consistent with the approved FFMP for the project. Weed species, or vegetation not considered appropriate for re-use on-site, will be removed and disposed of to an appropriately licenced facility. 6.16.8 Recommendation 5: During construction and after considering the outcomes of relevant information that becomes available during construction, appropriate measures are to be implemented to address identified deficiencies or undertake actions needed to address waste related impacts. If necessary, the WMP is to be reviewed and updated to include any additional required measures. 6.16.9 Recommendation 6: During construction, the development is to optimise the use of onsite cut and fill so as to reduce demand for fill from areas outside of the development area. 6.17 CLIMATE CHANGE IMPACTS 6.17.1 Existing Environment The climate of the locality is characterised by warm summers and mild winters with rainfall normally throughout the year (i.e., no distinct wet or dry seasons). Climate change generally refers to increased temperatures associated with the concentration of greenhouse gases in the atmosphere. It is now generally accepted that the release of certain gases including carbon dioxide and methane directly leads to climate change taking place. 6.17.2 Impact Assessment The construction of the project will result in the release of the following greenhouse gases which has the potential to contribute to the effects of climate change:

17/065 | Revised REF: Camden Valley Way Road Widening Works

•

• •

Carbon may be embedded in many of the materials used during construction including concrete, trees and pavements. There are also various greenhouse gas emissions associated with the extraction and production of materials used in the construction of road materials. Carbon dioxide and nitrous oxide will be generated from fossil fuel combustion in construction plant and the disposal or transport of materials. Methane will be released from the landfilling of any carbon-based waste, and potentially from fugitive emissions during the use of natural gas.

In the broader context, the effects of the construction phase of the project are considered relatively minor and potential impacts can be managed through the implementation of appropriate safeguard measures. 6.17.3 Mitigation Measures Notwithstanding the above, the following is recommended to mitigate climate change impacts preconstruction. 6.17.4 Recommendation 1: Pre-construction, specific measures are be outlined in the CEMP to ensure that construction minimises any potential impacts on or from climate change including: •

•

Plant, vehicles and machinery will be operated efficiently in accordance with the manufacturers guidelines to ensure optimal performance and be switched off when not in use; and Procedures will be set out for the management of extreme events including flooding, heatwaves and bushfires.

6.18 CONSTRUCTION/DEMOLITION IMPACTS 6.18.1 Existing Environment The project area is largely disturbed and either urban, public open space or semi-rural in nature. Existing trees located along the road reserve and within private property fronting Kirkham Lane are either native vegetation regrowth, exotic plants or weed species. Stockpiling is proposed within the northern parts of Lot 301 DP 1143646 lie within the boundaries of the project area. As Lot 301 is identified as containing an aboriginally significant site, an AHIP will be required prior to the commencement of works. 6.18.2 Impact Assessment Given large volumes of cut and fill for the project, environmental safeguards for erosion and sediment control should be implemented in addition to other measures such as management of air quality, traffic management, weed and pest control to minimise impacts during construction and demolition. Stockpiles of fill on the site should be located and managed in accordance with the guidelines in ‘Managing Urban Stormwater: Soils and construction – Volume 1’ (the Blue Book) 6.18.3 Mitigation Measures The following recommendations are made for to mitigate construction impacts.

6.19 SOCIAL IMPACTS The proposal is considered to result in positive social impacts through improving the Camden Valley Way traffic conditions which in outcome increases the efficient use of the road network for road users. 6.20 ECONOMIC IMPACTS The road widening activity proposed is anticipated to create local jobs through labour and equipment hire. Additionally, the new extension facilitated by the proposal will also create both short- and longterm employment through future alteration and scheduled maintained for the road network. 6.21 EUROPEAN HERITAGE While the location of the proposed works does not contain any items of European heritage significance, the area of activity is adjacent to Lot 101 in DP1143373 165 and Lot 162 in DP1087243 which are mapped as containing items of local heritage significance listed in the Camden Local Environmental Plan 2010 (reference: item no I105 Yamba and item no I104 Rheinbergers Hill). 6.21.1 Recommendation 1: The proposal should comply with the recommendations in the SoHI prepared by Niche Environment and Heritage, which include, but not limited to the following: • •

•

Vegetation clearing in and around Yamba should not negatively impact the fabric of the structure and work crews must be inducted to this effect. The proposed works which are conducted in proximity to the southern structure/cottage at ‘Yamba’ must be, through physical barriers and other controls, separated from the proposed works in order to prevent physical impacts to the fabric of this structure. The e encroachment of the proposed works on heritage curtilage should be minimised as much as possible, and after the works are completed, the identified heritage items must be updated with the resultant modification to their curtilage on council-supplied heritage mapping information.

6.22 CUMULATIVE ENVIRONMENTAL IMPACTS 6.22.1 Existing Environment Cumulative impacts could be experienced if construction or operation of the project coincided with construction or operation of other local development, such as other road upgrades, public work or private development. In this respect, it is noted that whilst the project involves two intersections within close proximity of each other construction will be undertaken separately to minimise potential impacts. 6.22.2 Impact Assessment The severity of potential cumulative impacts will vary between locations and would generally be dependent on the types of work being carried out, the timing and duration of the work relative to each other, the distance between the work and the receivers and the sensitivity of the receiver. For residents and motorists using the local network, coinciding construction activities may result in a lower visual amenity and air quality environment. These impacts would be short-term and can be justified by the long-term, positive impacts of the upgrade.

6.22.3 Mitigation Measures Further, the safeguards and management measures recommended are expected to effectively manage potential cumulative visual amenity and air quality impacts. 6.22.4 Recommendation 1: Pre-construction and during construction, potential cumulative impacts are to be explored and where identified, incorporated into the traffic management plan and the noise and vibration management plan. 6.22.5 Recommendation 2: During construction, management measures within the CEMP are to be reviewed in response to any complaints received and if warranted changed. It is therefore considered that any cumulative impacts can be managed through the implementation of the various management measures noted above.

ENVIRONMENTAL MANAGEMENT 7.1

ENVIRONMENTAL MANAGEMENT PLANS (OR SYSTEMS)

Safeguards and management measures have been identified to minimise adverse environmental impacts which could potentially arise as a result of the project. Should the project proceed, these recommended management measures will be applied during the construction phase. Project Environmental Management Plan/s (PEMP) and a CEMP will be required for the proposed activity. These plans will provide a framework for establishing how these measures will be implemented and who will be responsible for their implementation. The plans will be prepared prior to construction and should be reviewed and certified, prior to any physical work commencing. The CEMP will be a working document, subject to change if necessary. It is suggested that the currency of the plan is checked should an extended period of time elapse between its preparation and sign off and actual work commencing. The CEMP and PEMP will be developed in accordance with the specifications set out in the QA Specification G36 – Environmental Protection (Management System), QA Specification G38 – Soil and Water Management (Soil and Water Plan) and QA Specification G10 – Traffic Management. 7.2

SUMMARY OF SAFEGUARDS AND MANAGEMENT MEASURES

Environmental safeguards outlined in this document should be incorporated into the construction management phase of the project. These safeguards when employed properly will minimise the potential impacts of the project on the surrounding environment. The safeguards and management measures are summarised in Table 4. Table 4: Summary of Site-Specific Environmental Safeguards IMPACT Traffic and Access

ENVIRONMENTAL SAFEGUARDS A TMP is to be prepared and implemented in • accordance with the RMS Control at Worksites Manual (Version 4), Australian Standard 1742.3 Manual of uniform traffic control devices, and instruction from the Transport Management Centre. • Road users, local residents, pedestrians and cyclists are to be informed in advance of changed conditions, including any likely disruptions to access. • Real-time information is to be made available through temporary Variable Message Signs (VMS), and the media. • Materials are to be managed to minimise the number of haulage and delivery vehicles required on site. •

Designated site access points and haulage routes are to be used.

Affected areas are to be restored to a condition equivalent to that which existed prior to the commencement of the work. Aboriginal Heritage

As identified in the REF, Lot 301 DP1143646 (158 Camden Valley Way) is listed as potentially having an Aboriginal heritage item. A check of OEH's AHIP Register confirms an approval to destroy has been issued for this item (AHIP No. C0002506 dated 3/3/2017). It is also noted that the works associated with the project on this site are located along the immediate frontage of Camden Valley Way and in terms of disturbance of the ground is considered relatively minor. The Standard Management Procedure – Unexpected Heritage Items must be followed if a known or potential Aboriginal object(s), including skeletal remains. An AHIP of transfer of AHIP will be required prior to the commencement of works. It is recommended that prior to disturbance of the area

IMPACT

ENVIRONMENTAL SAFEGUARDS and its surrounds, a suitably qualified professional undertake a physical assessment of the site to determine if any items exist and if found appropriate action taken in consultation with the local Aboriginal community.

Non-Aboriginal Heritage

The following non-aboriginal heritage items have been identified over the site and with local significance: LEP I105 Yamba, Partially within the subject area. LEP I104 Rheinbergers Hill, Partially within the subject area. LEP I109 House, Located within 100m of but southwest from the Liz Kernohan connection section of the subject area. LEP I103 John Oxley, Located southwest and removed from the subject area. The works proposed to facilitate the development can be located wholly outside of the areas identified as containing local heritage significance. As such, the development is not deemed to impact on heritage items subject to the recommendations of the Statement of Heritage Impact prepared in support of the proposal.

Water Quality, Hydrology and Flooding

A Soil and Water Management Plan (SWMP) are to be prepared in accordance with QA Specification G38 and implemented as part of the CEMP. The SWMP is to identify all reasonably foreseeable risks relating to soil erosion and water pollution associated with undertaking the activity and describe how these risks are to be managed and minimised during construction. The Plan shall include arrangements for managing pollution risks associated with spillage or contamination on the site and adjoining areas and monitoring during post-construction. A site-specific Erosion and Sediment Control Plan (ESCP) will be prepared and included in the SWMP and CEMP. The ESCP is to identify detailed measures and controls that are to be applied to minimise erosion and sediment control risks including, but not necessarily limited to runoff, diversion and drainage points. The ESCP is to also include arrangements for managing wet weather events, including monitoring of potential highrisk events (such as storms) and specific controls and follow-up measures that are to be applied in the event of wet weather. Consistent with any specific requirements of the approved SWMP, control measures are to be implemented to minimise risks associated with erosion and sedimentation entry to drainage lines and waterways. That will include, but not necessarily be limited to: sediment management devices, such as sediment fencing, straw bales or sandbags; measures to divert or capture and filter water prior to discharge, such as drainage channels and first flush; installation of measures at work entry and exit points to minimise movement of material onto adjoining roads, such as rumble grids or wheel wash bays; and appropriate location and storage of construction materials, fuels and chemicals, including bunding where appropriate. •

Construction Noise

A Noise and Vibration Management Plan (NVMP) is to be prepared as part of the CEMP. The NVMP is to be prepared in accordance with the ICNG and is to identify: All potential significant noise and vibration generating activities associated with the activity; Measures to be implemented during construction to minimise noise and vibration impacts, such as restrictions on working hours, staging, placement and operation of work compounds, parking and storage areas, temporary noise barriers, haul road maintenance, and controlling the location and use of vibration generating equipment; Feasible and reasonable mitigation measures to be implemented; and

ENVIRONMENTAL SAFEGUARDS -

Arrangements for consultation with affected neighbours and sensitive receivers, including notification and complaint handling procedures contingency measures to be implemented in the event of non-compliance with noise and vibration criteria.

The majority of works are to be carried out during standard working hours (i.e. 7am – 6pm Monday to Friday, 8am –1pm Saturdays). Any work that is performed outside normal work hours or on a Sunday or public holiday is to minimise noise impacts in accordance with RMS’s Environmental Noise Management Manual Practice Note 7 – Roadworks Outside of Normal Working Hours and the Interim Construction Noise Guideline (ICNG). Construction personnel will be made familiar with the potential for noise and vibration impacts upon local residents and encouraged to take all practical and reasonable measures to minimise noise during the course of their activities. Where practical, the layout and positioning of noise-producing plant and activities at each work site will be optimised to minimise noise emission levels. Where practical, equipment are to be fitted with appropriate noise control measures and be in good working order. Where possible, non-beeper reversing movement alarms are to be used such as broadband (non-tonal) alarms or ambient noise-sensing alarms. Work site layouts are to be designed to reduce the need for reversing, potentially minimising the use of reversing beepers. Vehicles, plant and equipment are to be regularly inspected and maintained to avoid increased noise levels from rattling hatches, loose fittings etc. All vehicles, plant and equipment are to be turned off when not in use. Recommended safe working distances for vibration intensive plant is to be considered during construction planning. Mitigation may be required where sensitive receivers are located closer to the construction work than the safe working distances. Landscape and Visual

Project work sites, including construction areas and supporting facilities are to be managed to minimise visual impacts, including appropriate storage of equipment, parking, stockpile screening and arrangements for the storage and removal of rubbish and waste materials in a timely manner. Where required, temporary site lighting is to be installed and operated in accordance with AS4282:1997 Control of the Obtrusive Effect of Outdoor Lighting. A Landscape Management Plan (LMP), to ensure cost effective and consistent management of landscape works will be developed.

Socio-economic

A Communication Plan (CP) is to be prepared and implemented as part of the CEMP to ensure provision of timely and accurate information to the community during construction. The CP is to include (as a minimum): Mechanisms to provide details and timing of proposed activities to affected stakeholders, including changed traffic and access conditions; and Contact name and telephone number for the management of complaints. The CP is to be prepared in accordance with the RMS’s Community Involvement and Communications Resource Manual. Access for emergency vehicles is to be maintained at all times during construction. Any site-specific requirements will be determined in consultation with the relevant emergency services agency. Consultation is to be carried out with potentially affected properties prior to the commencement of and during work in accordance with the RTA’s Community Involvement and Communications Resource Manual. Consultation is to include but not limited to door knocks, newsletters or letter box drops providing information on the proposed work, working hours and a contact name and number for more information or to register complaints.

ENVIRONMENTAL SAFEGUARDS Consultation is to be carried out with all affected property owners and businesses during detailed design and construction to develop and implement measures to mitigate impacts on land use viability, infrastructure and severance. Consultation with local businesses would identify appropriate management strategies to avoid or minimise impacts on access and operations. This would include consideration of measures such as additional signage and alternative access arrangements. Disruptions to property access and consultation cohesion and traffic would be notified to team landowners at least five days in advance in accordance with the relevant community consultation processes outlined in the Traffic Management Plan.

Land use

Prior to the commencement of utility work, consultation is to occur with identified persons and organisations that may be adversely affected by service disruptions (such as businesses, educational and/or police facilities) to determine any special requirements or alternative service arrangements.

Soils and geology

A Soil Management Plan is to be prepared in accordance with QA Specification G38 and implemented as part of the CEMP. The SMP is to identify all reasonably foreseeable risks relating to subsurface impacts and pollution associated with undertaking the activity and describe how these risks would be managed and minimised during construction. That would include arrangements for managing pollution risks associated with spillage or soil contamination on the site and adjoining areas and monitoring during and postconstruction. In addition to the implementation of general erosion, sediment and water quality control safeguards, any sediment, washdowns, and refuelling. Where groundwater is intercepted during construction works, it is to be managed to minimise potential adverse impacts in accordance with the RTA Technical Guideline: Environmental management of construction site dewatering. These may include, but not necessarily be limited to: - Options to collect and store groundwater to enable recharge of the water table (such as via grassed swales); - Where recharge is not appropriate or feasible, discharging groundwater to the surface water drainage system following; and - Appropriate treatment to ensure discharged water is of sufficient quality. Prior to any dewatering activities being carried out, an approval must first be obtained in accordance with Section 92 of the WM Act. The rehabilitation of disturbed areas is to be carried out progressively and in accordance with: - Managing Urban Stormwater: Soils and Construction series; - RTA Landscape Guideline; and - Roads and Maritime Guideline for Batter Stabilisation Using Vegetation.

Contamination

A Contaminated Land Management Plan (CLMP) is to be prepared and implemented for any areas of land likely to be contaminated. The CLMP is to be prepared in accordance with relevant requirements of the Roads and Maritime Guideline for the Management of Contamination. If contaminated areas are encountered during construction, appropriate control measures are to be implemented to manage the immediate risks of contamination, such as the diversion of surface runoff, capture of any contaminated runoff or temporary capping. All other work that may impact on the contaminated area are to cease until the nature of the contamination has been confirmed and any necessary site-specific controls or further actions identified in consultation with the Environment Manager and / or EPA. A site-specific emergency spill plan is to be developed and include spill management measures in accordance with the Roads and Maritime Code of Practice for Water Management and relevant EPA guidelines. The plan would address measures to be

CONCLUSIONS

This REF has been prepared for Camden Council by Monteath & Powys Pty Ltd to satisfy obligations under Part 5 of the Act. It has been prepared in accordance with Section 5.1 of the Act and provides an environmental assessment considering the factors outlined in section 171 of the Regulation. Review of the proposal has determined that the activity is not likely to significantly affect the environment. The activity would not impact on, or require any substantial changes to, existing site activities. As such, it is concluded that an Environmental Impact Statement is not required for this activity. As identified in the REF, Lot 301 DP1143646 (440 Camden Valley Way) is listed as potentially having an Aboriginal heritage item. The works associated with the project on this site are located along the immediate frontage of Camden Valley Way and in terms of disturbance of the ground is considered relatively minor. Further, the proposal is supported by a Heritage Impact Assessment prepared by Niche Heritage and Environmental which identifies the actual location of the heritage items with recommendations to maintain an acceptable risk to the heritage value of the subject area and identified heritage items. 9.1

JUSTIFICATION

The upgrades are required to improve the long-term capacity of the Camden Valley Way network in the Elderslie area and will enhance traffic flows and address peak period delays at the identified intersections. Traffic modelling conducted for the project indicates that the identified intersections are currently performing, although will deteriorate unless an upgrade is implemented given the population growth being experienced in the area. The potential environmental impacts of the project have been identified and they include loss of some vegetation, visual impacts and noise. These impacts will be minimised as far as practicable during the finalisation of the design and can be adequately managed. On balance, the benefits derived from proceeding with the project are considered to outweigh the potential impacts. On this basis, the project is considered justified. 9.2

ECOLOGICALLY SUSTAINABLE DEVELOPMENT

Ecologically sustainable development (ESD) is a development that improves the total quality of life, both now and in the future, in a way that maintains the ecological processes on which life depends. The principles of ESD have been a consideration throughout the development of the Proposal. The EP&A Act recognises that ESD requires the effective integration of economic and environmental considerations in decision-making processes. The four main principles supporting the achievement of ESD are considered in the context of the proposal below. 9.3

PRECAUTIONARY PRINCIPLE

The precautionary principle deals with certainty in decision-making. It provides that where there is a threat of serious or irreversible environmental damage, the absence of full scientific certainty should not be used as a reason to postpone measures to prevent environmental degradation. The threat of serious or irreversible environmental damage is one of the essential preconditions to the engagement of the precautionary principle. As no threat of serious or irreversible environmental damage has been identified the precautionary principle does not apply.

9.4

INTER-GENERATIONAL EQUITY

Social equity is concerned with the distribution of economic, social and environmental costs and benefits. Inter-generational equity introduces a temporal element with a focus on minimising the distribution of costs to future generations. The impacts of the proposal have been identified as short term and manageable. Benefits will be experienced over a longer period. 9.5

CONSERVATION OF BIOLOGICAL DIVERSITY AND ECOLOGICAL INTEGRITY

The principle of internalising environmental costs into decision making requires consideration of all environmental resources which may be affected by a project including air, water, land and living things. While it is often difficult to place a reliable monetary value on the residual, environmental and social effects of the project, the value placed on environmental resources within and around the activity area is evident in the extent of environmental investigations, planning and design of impact mitigation measures to prevent adverse impacts. 9.6

CONCLUSION

In accordance with Part 5 of the Act, Camden Council, as the determining authority for the activity, has fulfilled its duty to consider the environmental impact of the proposed activity. As such, the proposed works can be carried out by or on behalf of Camden Council without consent under the provisions of the State Environmental Planning Policy (Transport and Infrastructure) 2021.
