Client, file Executive summary Roads and Maritime Services (RMS) is proposing to replace the existing bridge over Deadmans Creek along Heathcote Road at Sandy Point. The proposed work would comprise construction of a new bridge over Deadmans Creek and would include realigning Heathcote Road on the approaches to the bridge. The proposed works would also involve improving the road drainage system at the intersection of St George Crescent and Heathcote Road, about one kilometre south of the existing bridge. Following commissioning of the new bridge, the existing bridge would be demolished. The replacement bridge is needed to improve safety for motorists and other road users crossing Deadmans Creek on Heathcote Road. This aligns with RMS’s ongoing commitment to provide a safe and efficient road network for NSW road users. During the concept design planning phase, RMS undertook a process of community and stakeholder consultation. In November 2012, RMS distributed a community update to local residents in Sandy Point and nearby suburbs. This community update outlined the proposal to replace the bridge and invited the community and stakeholders to view and discuss the concept two community information sessions on 10 November 2012 and 14 November 2012. The concept design was also publically displayed at the Liverpool and Engadine Motor Registries. At the community information sessions, members of the project team, including RMS engineers, designers and communication officers responded to questions raised by members of the community. About 75 community members attended these sessions. From 5 November 2012 to 30 November 2012, RMS sought written comments from the community regarding the concept design. A project telephone number was also provided for verbal inquiries. Feedback was received from 53 community members and 92 issues were raised. This Community Issues Report summarises the issues raised during the consultation period for the concept design and outlines RMS responses to these issues. This report is available for viewing on the RMS website. It also forms part of the review of environmental factors (REF) prepared for the preferred option (refer to Appendix E of the REF). Where possible, RMS has incorporated the community feedback into the design for the proposed replacement bridge.

The proposed work would include: Realigning Heathcote Road in the vicinity of the bridge Improving drainage at the intersection of St George Crescent and along the alignment of Heathcote Road in the vicinity of the bridge. Demolishing the existing bridge, following the commissioning of the new bridge. The proposal would provide a wider, safer alignment for this section of Heathcote Road, with key the features including: Two 3.5m lanes, one in each direction. Shoulders with widths of 2.0 metres and a 0.6 metre wide median on the bridge and approaches. A raised road alignment, providing for increased flood immunity from 1 in 5 years, to 1 in 20 years flood level. An improved road alignment, with reduced grades and better curve geometry. Widening the left turn lanes into and out of St George Crescent at the intersection Improved drainage at the intersection of St George Crescent. The key features of the main bridge structure would include: A new 11.6 metre wide concrete bridge, upstream from the existing structure. Retaining walls on the bridge approaches to support the raised level of the bridge. A temporary personnel crossing of the creek during the construction period. 1.2 Proposal objectives The key objectives of the proposal are: Provide a wider bridge over Deadmans Creek. Provide a safe road environment for motorists along Heathcote Road in the vicinity of Deadmans Creek. Minimise impacts on the environment and locality. Improve the flood immunity of the Deadmans Creek crossing. Develop a cost-effective solution. 1.3 Purpose The proposed replacement of the existing bridge over Deadmans Creek is needed to improve the safety conditions for motorists and other road users crossing Deadmans Creek on Heathcote Road. The strategic need for the proposal is aligned to RMS’ ongoing commitment to provide a safe and efficient road network environment for NSW road users. Replacement of the bridge over Deadmans Creek along Heathcote Road Sandy Point Community Issues Report 1 As part of the proposal, RMS undertook a period of community and stakeholder consultation. 1.4 Existing road and infrastructure Heathcote Road is an arterial road, which is an important link between south-west Sydney and the Princes Highway at Heathcote. It services commercial, local and through traffic from Liverpool to Wollongong and the Holsworthy Army Base. Heathcote Road is mostly located in a semi-rural environment and the signposted speed limit varies from 70km/h to 100km/h along its length. It is bordered by undeveloped land, with some residential suburbs at the Liverpool end of Heathcote Road. The section of Heathcote Road which comes under the proposal is signposted at 80km/h and has a narrow, steep and winding curve when approaching Deadmans Creek in either direction and does not meet today’s design standards. The existing bridge is a six-span structure with a total length of 37.1 metres. The existing carriageway is 6.6 metres wide with one lane in each direction. 1.5 Crash history In the period between 2002 and 2011, seven crashes were recorded on Heathcote Road, from north of the bridge to the intersection at St George Crescent. These crashes included one injury and four incidents where vehicles required towing from the scene. In addition, the existing bridge over Deadmans Creek was damaged in 2012 as a result of two crashes involving heavy vehicles. The recent crash history suggests there is a risk of vehicles either crashing or clipping each other while travelling on the bridge. This proposal would provide an improved road alignment on the northern and southern approaches and widen the Deadmans Creek crossing, improving road safety for all users. 1.6 Options selection RMS investigated a range of potential options to replace the existing bridge over Deadmans Creek. The design development process involved input from RMS business units Bridge Section, Infrastructure Asset Management and the Transport Management Centre. A series of preliminary investigations were initially undertaken within the study area to identify environmental and engineering constraints. Based on these investigations, a range of options were developed. A workshop was held in May 2012 to assess the options that had been prepared. The objective of this workshop was to: review the various road and bridge alignment options. select a preferred alignment option for further refinement. Replacement of the bridge over Deadmans Creek along Heathcote Road Sandy Point Community Issues Report 2 The options were assessed against a range of criteria including: Road safety benefits. Environmental impacts. Geotechnical and hydrological constraints. Engineering requirements and constraints (including alignment and grading). Traffic impacts and site access availability. Estimated project cost. Ease of construction. Four options were identified. A description of each of the options is provided below. 1.6.1 Design options to replace the bridge Four design options for the project were investigated for the life of the project’s development: Option 1A: Replace the existing bridge with a wider, longer bridge, which would be located upstream (west) of the existing crossing and demolish the existing bridge after commissioning the new bridge. Option 1B: Replace the existing bridge with a wider, longer bridge, which would be located downstream (east) of the existing crossing and demolish the existing bridge after commissioning the new bridge. Option 2: Retain the existing bridge for northbound traffic using Heathcote Road and construct a new bridge for southbound traffic using Heathcote Road. Once the new bridge has been completed, demolish the existing bridge and extend the new bridge on the upstream (west) side for an ultimate two-lane configuration. Option 3: Widen the existing bridge on the downstream side (east) of Deadmans Creek. 1.6.2 The preferred option Option 1A was selected as the preferred option and is the subject of the REF. Option 1A would best achieve each of the proposal objectives and assessment criteria identified in Section 1.2 and 1.6 of this report. In particular, the development of an improved alignment for the Deadmans Creek Bridge would improve the safety of this section of Heathcote Road and reduce the likelihood of crashes in this area. An artist’s impression of the preferred option is shown in Figures 1–1 to 1–2b. Since the community update that presented the proposal in November 2012 some design refinements have been made based on community, stakeholder and agency feedback and the results of ongoing technical investigations. Further discussion of the options considered and the preferred option as well as design refinements will be provided as part of the REF.

Figure 2-1 to Figure 2-3 show the community update letterbox distribution zones. The Community Update outlined the project development process and invited the community to attend one of the community information sessions on the concept design of the preferred option. A copy of the Community Update is provided in Appendix A.

The sessions were held on Saturday 10 November 2012 and Wednesday 14 November 2012. Approximately 75 community members attended the community information sessions. At the community information sessions, members of the project team including RMS team members which included engineers, designers and communications staff, displayed the concept design for the preferred option and responded to questions raised by the community. Community members had the opportunity to respond to RMS on the concept design in writing by completing a feedback form, provided at the community information sessions and returning it to RMS by the 30 November 2012. Written comments were also accepted via email and a project telephone number was provided for enquiries. The concept design was also placed on display at the Liverpool and Engadine Motor Registries. 2.3 The respondents RMS sought community feedback on the concept design from 5 November 2012 until 30 November 2012. This Community Issues Report categorises the community responses, summarises the issues raised and outlines the RMS responses to the issues raised by the community. This Community Issues Report will form part of the REF prepared for the preferred option. RMS received 53 submissions in response to the concept design for the preferred option (Option 1A) from members of the community. For the purposes of this report, the 53 respondents were categorised by the type of stakeholder making the submission, these categories included: Sandy Point resident. Not specified. Community group. Pedestrian/cyclist. Road user (non-resident). Government agency. Other. Other local resident. Figure 2-4 and Table 2-1 shows the percentage of respondents by the above stakeholder categories. The majority of respondents (36 people or 68 per cent) were Sandy Point residents. It should be noted that for the purposes of this report, respondents were categorised according to the information they supplied on their feedback forms and emails. RMS is aware the categories listed above are not mutually exclusive. For example, a resident of Sandy Point would almost certainly be a road user. However, for simplicity of reporting, it was necessary to specify one category per respondent. For this reason, a reference to a respondent as a road user in this report indicates the respondent is not a resident of Sandy Point or has not provided a residential address in the community feedback form.

For the purposes of this report, the 92 issues were sorted into the following five categories: Access. Safety for road users. Design. Environmental impacts. Other. Figure 2–5 and Table 2-2 provides a summary of the number of responses for each issue category. The issues of Access and Safety for road users concerned the majority of respondents. Another 20 per cent of respondents were concerned with design, and the impact design can have on motorists safety.

Table 2-4 RMS response by subcategory Issue category Issue subcategory Access Safe access to and from St George Crescent from Heathcote Road Safety of the intersection of St George Crescent and Heathcote Road. Improved entry and exit onto Heathcote Road from Sandy Point. RMS response A full upgrade of the St George Crescent intersection does not form part of the scope of this project, which is to widen or replace the bridge over Deadmans Creek; This narrow bridge represents a safety issue for road users. Funding has been provided to RMS to address the safety of road users using the bridge. For the period between 2002 and 2011, seven crashes were recorded on Heathcote Road from north of the bridge to St George Crescent. At this time, the crash data does not support the need to upgrade the intersection and as such, funding to carry out a full upgrade of the intersection has not been provided to RMS. Following further investigation of the areas drainage, RMS is proposing to improve drainage on the southern road approach to the bridge. This requires some modifications to be made to the St George Crescent intersection. Although these modifications are principally designed to improve drainage, widening the left turn lanes into and out of St George Crescent at the intersection will improve the provision of left in/left out turn facilities at the intersection, thereby improving safety for all road users wishing to turn left at this location. The NSW State Government has identified Heathcote Road for a future corridor strategy, which would investigate its operation and needs into the future. Any major upgrade to the St George Crescent intersection will need to be considered as part of that overall improvement package. As part of the development of this improvement package RMS would submit a case to Transport for NSW for funding to investigate Heathcote Road as other projects, priorities and resources allow. If funding is secured, RMS will review the St George Crescent intersection at that time. Safe pedestrian and cyclist access on the proposed bridge and along Heathcote Road Provision of a cycle lane/pedestrian path. Pedestrian and cyclist connectivity with Heathcote Road. The proposed bridge would not provide a separate pedestrian or cycle path as there are no existing paths along this road for a path over the proposed bridge to connect to hence would be an isolated section with no 'connectivity' lines. Some suggestions were also made to retain the existing bridge for pedestrian access and as a corridor for emergency vehicles. This section of Heathcote Road is a narrow two lane road with sign-posted local speeds of up to 80km/h and has no dedicated footpath or cycleway and again would be an isolated section with no 'connectivity' lines. Reuse of the existing bridge would not be feasible unless additional major road work is completed and due to the current alignment, would not be suitable for reuse in any future road upgrade. Retaining the existing bridge would also require ongoing maintenance to an aging infrastructure. Replacement of the bridge over Deadmans Creek along Heathcote Road Sandy Point Community Issues Report 15 Issue category Issue subcategory Safety for road users Safety improvements on the proposed bridge and surrounding road network Increased driving speed on the proposed bridge. Safe exit from St George Crescent onto Heathcote Road. Design Number of lanes on the proposed bridge Proposed bridge should be two lanes in each direction. Proposed bridge should be designed to accommodate for future developments. Environmental Impacts Operational noise impacts for local residents due to increased traffic Noise reduction barriers should be placed along Heathcote Road. Existing noise impacts in Sandy Point due to traffic and heavy breaking. Flora and fauna impacts of the proposed bridge Incorporation of wildlife underpass/crossing into the design Impacts to fauna and flora from proposed bridge. RMS response RMS acknowledges that the wider bridge and approaches may result in some increased driving speeds along this section of Heathcote Road. However, on balance, RMS considers that the improved vertical alignment, improved sight lines and sight distance, two metre wide shoulders and a central 0.6 metre median to separate traffic will improve safety for all vehicles using this route. The proposal involves providing a new, wider two-lane bridge. While the provision of a dual carriageway was considered, it was not deemed viable due to existing infrastructure and environmental constraints. RMS understands no decision has been made on the Gandangara land release or the Moorebank intermodal development proposals. The proposed two-lane bridge is designed to meet current traffic demands and identified safety risks. The NSW State Government has identified Heathcote Road as a candidate for a future corridor strategy, which would investigate its operation and needs into the future. Design has considered the implications of a potential future upgrade of Heathcote road and the proposed bridge fits well with any future upgrade. No immediate upgrade to the number of lanes on Heathcote Road is proposed at this time. The noise impacts of this proposal have been assessed in developing the REF. Potential impacts on amenity may result from traffic noise. However, given the proximity of the existing road to houses within Sandy Point, the rural nature of the proposal site and the proposed improved road surface of the proposal, changes in amenity due to increased noise from the proposal are expected to be minimal. The proposed bridge would be about 36 metres longer than the current bridge. This would ensure that the current level of fauna and flora access and connectivity along Deadmans Creek underneath the bridge and its approaches is maintained and may result in improved access due to the proposed increased length and resultant area underneath, allowing for improved travel between upstream and downstream areas. Replacement of the bridge over Deadmans Creek along Heathcote Road Sandy Point Community Issues Report 16 Issue category Issue subcategory Flood mitigation on the surrounding road network and drainage on the proposed bridge Dredging of Deadmans Creek would assist in flood mitigation. Heathcote road, on the Liverpool side of the existing bridge will still be flood liable. Other Funding for construction RMS response The proposed replacement bridge would be higher than the existing bridge, which will not only improve the vertical alignment but also help to increase the flood immunity of the bridge. At this stage no full scale dredging of Deadmans Creek is considered necessary or proposed. Flooding and drainage impacts of the proposal have been assessed in detail and will be available in the REF. Another element of the proposal is to upgrade the drainage system in the vicinity of the intersection of St George Crescent and Heathcote Road. The proposal for widening the crossing over Deadmans creek is funded by the State Government, as part of the RMS Infrastructure Asset Management budget. Replacement of the bridge over Deadmans Creek along Heathcote Road Sandy Point Community Issues Report 17 3 Conclusion RMS has considered and responded to the issues raised by the community in relation to the concept design for the proposed replacement of the bridge over Deadmans Creek along Heathcote Road, Sandy Point. RMS has taken the issues raised during community information sessions into account during the assessment of the REF. RMS will place on the website the REF for community and stakeholder information. Following the determination of the REF, work will start on the detailed design of the project. Once the design is finalised, a further update will be provided to the community before works begin. Information on the progress of the project will continue to be updated on the project website.
