Boulevard The Mount Alexander Road ‘boulevard’ runs 3.9 kilometres from the Tullamarine Freeway in the north to the Moonee Ponds Junction in the south. This includes 1.0 kilometre of Bulla Road and 2.9 kilometres of Mount Alexander Road. It has a typical corridor width of 60 metres that accommodates public transport and up to six lanes of traffic. Public transport that uses this corridor includes seven bus services and the 59 tram. These services connect the activity centres of Essendon North, Essendon and Moonee Ponds. N 0 250 500 750 1000 Metres GHD | Essendon Junction Grade Separation, Draft Feasibility Assessment Report – Project No. 3132598 | March 2015 | 45 Shared lanes Two lanes of traffic run in either direction along Mount Alexander Road through Essendon Junction. Where the road passes under the existing rail bridge, the roads become more constrained and congested with trams moving from a dedicated reserve to sharing the second road lane with cars. This creates delays for the tram services. Road corridor below rail bridge reduced to four lanes with trams merging from dedicated reserve to lane shared with cars. N 0 50 100 150 200 Metres 46 | March 2015 | Essendon Junction Grade Separation, Draft Feasibility Assessment Report – Project No. 3132598 | GHD Signalised intersections There are existing signalised intersections at Mount Alexander Road / Buckley Street and Buckley Street / Russell Street / Rose Street. The junction at Mount Alexander Road and Fletcher Street is a roundabout with signalised crossings. Careful attention would need to be paid to the Mount Alexander Road / Fletcher Street intersection with any new traffic conditions. If Raleigh Street is connected through to Mount Alexander Road, as part of the grade separation project, then a new signalised intersection may have to be established at Mount Alexander Road / Raleigh / Shamrock Street. N 0 50 100 150 200 Metres GHD | Essendon Junction Grade Separation, Draft Feasibility Assessment Report – Project No. 3132598 | March 2015 | 47 Pinched alignment Street alignment The VicTrack site and private site at the west corner of Mount Alexander Road and Fletcher Street are the only properties along the boulevard that extend into the 60 metre wide road corridor. This would be due to historical reasons with the VicTrack land extended north east to the retaining wall of the road underpass. As a historical anomaly, the 45 metre wide restriction through the junction could be used as a positive opportunity to bring development on the two sides of Mount Alexander Road closer together. This would help integrate the Neighbourhood Centre and render Mount Alexander Road less of a dividing feature. N 0 50 100 150 200 Metres 48 | March 2015 | Essendon Junction Grade Separation, Draft Feasibility Assessment Report – Project No. 3132598 | GHD Boulevard alignment Street alignment Conversely, bringing Mount Alexander Road to natural ground line could provide an opportunity to widen the boulevard corridor out to its original 60 metres and provide maximum benefit for public transport and road capacity. The impact of the widened boulevard on pedestrian connectivity would need to be considered. However, the width of the 60 metre boulevard is unlikely to be detrimental to the human scale if the pedestrian heart of the precinct is near the station and the boulevard becomes a transport spine.

This could provide a tram super stop in a plaza environment adjacent any new development on the VicTrack site with strong interchange potential to buses and rail. The trams would have to cross traffic using signals at Mount Alexander Road/ Shamrock and Mount Alexander Road/ Fletcher intersections. 59 tram Provision for future tram route from Moonee Ponds Tram interchange in plaza environment N 0 50 100 150 200 Street alignment Metres GHD | Essendon Junction Grade Separation, Draft Feasibility Assessment Report – Project No. 3132598 | March 2015 | 51 Street alignment 59 tram Provision for future tram route from Moonee Ponds Tram interchange in boulevard environment N 0 50 100 150 200 Metres 52 | March 2015 | Essendon Junction Grade Separation, Draft Feasibility Assessment Report – Project No. 3132598 | GHD Tram boulevard option/ widened Alternatively, the 59 tram could maintain the typical pattern along Mount Alexander Road and be accommodated in the central reserve between the boulevard trees. A tram super stop could act as a refuge for pedestrians crossing from one side of the activity centre to the other. This option could work with the ‘boulevard’ alignment whereby the VicTrack parcel boundary is adjusted. Tram boulevard option/ pinched Street alignment Alternative to the tram plaza option, the 59 tram could maintain the typical pattern along Mount Alexander Road and be accommodated in the central reserve between the boulevard trees. A tram super stop could act as a refuge for pedestrians crossing from one side of the activity centre to the other. This option could work with the ‘pinched’ alignment whereby no adjustment to the VicTrack parcel boundary would be required. 59 tram Provision for future tram route from Moonee Ponds Tram interchange in boulevard environment N 0 50 100 150 200 Metres GHD | Essendon Junction Grade Separation, Draft Feasibility Assessment Report – Project No. 3132598 | March 2015 | 53 Street alignment Bus station option The majority of buses move through the activity centre stop in Russell Street, adjacent the train station.

The primary access points to the station will affect the pedestrian traffic in the surrounding streets. Therefore they should be strategically placed to aid activation in the desired areas outlined in the Structure Plan. This train station access point would shift greater emphasis and activation onto Mount Alexander Road. A disadvantage of this option is that the access point is further away from the existing heritage listed station building. Adaptive re-use of the building would have to be explored.

This option shifts the emphasis and activation into the centre of the VicTrack site and is conducive to creating a ‘city square’ type environment. Access to the station is within an acceptable proximity to the existing heritage listed station. Therefore, this option provides the opportunity to use the existing building for an ancillary use to the station as preferred by Heritage Victoria.

This option shifts the emphasis and activation created by the station into the centre of the VicTrack site and is conducive to creating a ‘city square’ type environment. Unlike access option 3, access would be provided directly through the existing heritage listed station building. As such, this design provides the best opportunity to take advantage of the heritage building for an ancillary use as preferred by Heritage Victoria.

Above ground Divider implications The above ground implications of the grade separation were explored in a number of high level design options. These options illustrate design ideas that will be further considered in the Essendon Junction structure plan process. 60 | March 2015 | Essendon Junction Grade Separation, Draft Feasibility Assessment Report – Project No. 3132598 | GHD Option 01 – do minimum Street alignment The ‘do minimum’ option would retain the existing ‘pinched’ alignment along Mount Alexander Road by retaining the boundary of the VicTrack site. The dead end at Raleigh Street would be left unchanged. The southern portion of the VicTrack site could potentially become a plaza defined by the buildings on the freed northern and southern parcels. This opens up the activity centre to increased pedestrian permeability from Russell Street through to Rose Street. Alternatively the southern area could be used for an off-street bus interchange adjacent to the heritage station building.

Raleigh street would be connected through to Shamrock Street to increase permeability. Connect Raleigh Street through to Shamrock Street A ‘straight’ pedestrian link would be created through the VicTrack site to connect Rose Street to the junction via Fletcher Street. This would create a visible connection to Fletcher Street with clear sight lines. The southern portion of the VicTrack site could potentially become a plaza defined by the buildings on the freed northern and southern land parcels. This opens up the activity centre by increasing pedestrian permeability from Russell Street to Rose Street. Alternatively the land could be used for an off-street bus interchange adjacent to the heritage station building.

Raleigh street would be connected through to Shamrock Street to permit vehicle access and increase pedestrian permeability. Connect Raleigh Street through to Shamrock Street A pedestrian link would be created to connect Rose Street to Essendon Junction. This link would be adjacent the potential plaza or off street bus interchange in the southern portion of the VicTrack site.

The disadvantage of a dedicated bus interchange is that it could create inactive frontages along Mount Alexander Road and Russell Street. The bus interchange would largely be a ‘dead’ space at night time, which is unfavourable to personal security. This may be detrimental to the success of the pedestrian area to the south and may act as a barrier to the northern portion of the site. Connect Raleigh Street through to Shamrock Street The advantage of having a separate bus interchange area is that it would free up the southern portion of Russell Street from buses. The dedicated bus interchange is also in closer proximity to the tram interchange along Mount Alexander Road.

The ample space between the VicTrack development and the historic building to the south enhances pedestrian permeability without having a dedicated link separate to the plaza. The passing by foot traffic would informally activate the plaza and provide some passive surveillance. The plaza would be bounded by Rose Street and Russell Street and well defined by the building edges to the north and south.

Making Russell Street more pedestrian focused was one of the key ideas that arose from community consultation. The large plaza would act as a continuation of the pedestrian focused environment at Russell Street and enhance permeability from Rose Street to Essendon Junction.

Their views on the project are expressed in the following report. 120 | March 2015 | Essendon Junction Grade Separation, Draft Feasibility Assessment Report – Project No. 3132598 | GHD CONFIDENTIAL CONFIDENTIAL VICTORIAN DESIGN REVIEW PANEL Essendon Junction Grade Separation Project February 2014 Essendon Junction Grade Separation Project Design Review Report – 19 February 2014 We thank the Moonee Valley City Council (MVCC) and GHD for presenting the Essendon Junction Grade Separation Project to the Victorian Design Review Panel. We also thank VicTrack and Heritage Victoria for attending and contributing to the session. This is a fascinating project with a number of complex contextual issues. We support MVCC’s concerns about the functionality of the Essendon Junction and its surrounding precinct and also the balanced approach being taken to a large-scale infrastructure intervention with significant heritage considerations. This grade separation project has the potential to unlock a great number of opportunities for central Essendon and we are pleased to see MVCC leading this infrastructure project with an openness to the urban regeneration possibilities. Strategic considerations We commend MVCC’s ‘big picture’ view of this infrastructure project and the ambition to improve pedestrian connections in an activity area that is currently divided by significant road and rail barriers. The resolution of the Junction for pedestrians is an important focus of this project, however the Junction is not necessarily a place within Essendon to which people are drawn. There is an important strategic question to be determined: where is the ‘heart’ of the activity area? We suggest the exercise of mapping people movements through the precinct would be beneficial to understand where people are moving to, the timing of journeys and the barriers to moving through the precinct by foot. Giving consideration to how people engage with the Essendon activity area will give clues to the direction the project needs to take and clarify the options that align with the vision for the area. While we acknowledge there are multiple possibilities for the public realm that can result from a grade separation at Essendon, we suggest the opportunities to be pursued will become clearer following this type of strategic analysis. We strongly encourage the design of the Junction precinct as a whole rather than focus too heavily on the individual interventions. Essendon has a history and an identity and it is important that these elements of the place are strengthened and respected as the design develops. Rail-under-Road Options The rail-under-road solution proposes a good outcome for Essendon and enables opportunities to reconnect and revitalise the Essendon centre. The next stage of the investigation should provide a more comprehensive understanding of the benefits associated with this solution in order to demonstrate clearly the value that such an investment can provide. We note that two options for rail-under-road have been developed and suggest that this type of assessment will be useful should the project team be required to establish which solution offers the greater benefits or delivers a better result in terms of public outcome and development potential. Of the two options presented, we acknowledge that the option that proposes a section of Mt Alexander Road being raised could be managed if properties and future development in the area is planned for in a way that accommodates the raised ground level. A commitment to adapting the 2 GHD | Essendon Junction Grade Separation, Draft Feasibility Assessment Report – Project No. 3132598 | March 2015 | 121 CONFIDENTIAL CONFIDENTIAL surrounding urban environment to suit this grade change would be critical to ensuring the existing barrier at Mt Alexander Road is simply not replaced with another form of barrier. The Panel agreed that such an endeavour would take considerable time and additional investment before a good urban outcome could be achieved. It was noted that it is often a false economy to undertake a less expensive option that is not able to deliver the same level of enduring benefits that will be offered by a more expensive option. In this instance, the indicative cost difference between the two options seems negligible in an investment of this scale and, for all the above reasons, we offer support for the rail-under-road solution that restores Mt Alexander Road to its original grade. Essendon Junction and Mt Alexander Road The proposal to extend the Mt Alexander Road ‘boulevard’ through the Essendon Junction is supported in principle. Returning this section of Mt Alexander Road to its original 60-metre alignment may be perceived to be in conflict with the idea of improving pedestrian connectivity in the precinct. However, we suggest that if designed appropriately this central section of the boulevard can provide a strong civic outcome and a pedestrian-friendly environment. A similar scaled boulevard, Whitehorse Road, Box Hill, offers a useful precedent for how the median can be designed to be a high quality public realm and functional space for people and transport. We encourage consideration of how pedestrians can be afforded priority in central Essendon and of how the Mt Alexander Road barrier can be overcome. The early ideas about integration of a tram stop with crossing points on this section of the boulevard deserves further investigation, along with other opportunities such as designing the median as a plaza, with the potential inclusion of a Station entrance. A boulevard does not have to be of a consistent character for its entire length and there are opportunities for this section of Mt Alexander Road to respond to its location as well as provide functional improvements at the Junction. We support the proposal to introduce trees as a means of reinforcing the existing boulevard character north and south of the Junction. This is a unique and rare opportunity for MVCC to rethink the urban structure in central Essendon. We encourage the team to be inventive in overcoming the difficulties at the Junction and not be constrained by the existing corners and edges that may be contributing to the problem. VicTrack – Carpark Site VicTrack has an important stake in the re-visioning of central Essendon given the scale of its landholdings and its long frontage to Mt Alexander Road at the Junction. We encourage VicTrack and MVCC to continue to discuss leveraging opportunities from the available land within the Essendon Junction precinct. There is obvious development potential on the VicTrack site and we support a mixed-use proposal that makes a strong contribution to central Essendon and sets the benchmark for further development within the precinct. Appropriate development on the VicTrack land has the potential to unlock value on both sides of Mt Alexander Road. It is important that the east side of Mt Alexander Road contributes in proportion with the VicTrack site and in line with the vision for the Essendon Junction more broadly. We suggest investigating how the VicTrack land could form part of a broader strategy for development in the precinct: for example, offering VicTrack land as an offset to release the land opposite for development. the next stage of investigation include 3D massing and sectional diagrams to explore the scale of built form to ensure that it is appropriate and contributory. Essendon Station Complex We encourage further investigation into the possibilities for adaptive reuse of the Essendon Station complex, in partnership with Heritage Victoria, to determine a solution that maintains the integrity of the Station’s heritage qualities while allowing for contemporary transport standards. While re-use of the heritage Station as an entry to the new underground railway platforms is an appealing idea, the resultant interventions are potentially severe. Further investigation of this possibility is required. The option to adapt the Station precinct to a place for pedestrians, potentially as a ‘city square’ with retail, is positive. As the options for the Station precinct develop, consideration of the scale of new public spaces, the integration of laneways and connections, and the proposed landscaping, will become increasingly important. The presented drawings were useful to demonstrate possible opportunities for the precinct, but consideration now needs to be given to the location of pedestrian links through the Station and broader VicTrack site. Next Steps In addition to the comments above, resolution is needed about whether the railway corridor will accommodate freight trains and whether a curved track at the Station platform acceptably meets universal design requirements. The three transport modes within the precinct need to work cohesively together while establishing central Essendon as a desirable place for people. While this early stage of the project is assessing feasibility, the next stage needs integrated and visionary design thinking to unlock the opportunities that this level of investment and intervention may enable in Essendon. We encourage MVCC to develop the concepts and options in more detail in order to inform better the choices that will have to be made. We offer MVCC the support of the Office of the Victorian Government Architect through design workshop facilitation and a second review of the proposal by the Victorian Design Review Panel at the next appropriate design stage. Geoffrey London Victorian Government Architect Up to 12 storeys of development are allowed on the VicTrack site. We question the ‘fit’ of built form of this scale within the Essendon context. While we understand that the economic feasibility of development on this site is an important factor in the case for the grade separation project, this needs to be balanced with the possible impact of overdevelopment in this area.

Option four is a further developed version of Option 3 that responds to a number of rail technical requirements specified by PTV, including but not limited to the length and number of platforms. Table 1.a provides a list of PTV’s requirements and commentary on how those are met by Option 4. In addition to the design work associated with Option 4, GHD also considered the impact of the rail grade separation on the gas main in Buckley Street and the potential impact of the Mt Alexander Road rail under road grade separation on the Shamrock Road intersection. 124 | March 2015 | Essendon Junction Grade Separation, Draft Feasibility Assessment Report – Project No. 3132598 | GHD GHD | Essendon Junction Grade Separation, Draft Feasibility Assessment Report – Project No. 3132598 | March 2015 | 125 Table 1.a PTV’s requirements and option 4 Transport Requirement Heavy Rail Track Description Option 4 Status Maintain 2 broad gauge tracks within the Newmarket and Craigieburn corridor section Maintains 2 broad gauge tracks Has been addressed Maintain 3 broad gauge tracks from approximately 300m north of Essendon precinct Maintains 3 broad gauge tracks Has been addressed The proposed track configurations have been design to permit parallel movements for turn-back operations as well as through services without conflict Allows parallel movements for turn-back operations as well as through services without conflict Has been addressed All turnouts to be 1:15 to allow for 65 km/h operational speeds through turnouts where possible Base design provides 230 m platforms with 1 in 15 turnouts and therefore 65 km/h through turnouts. However, R300 m curves at ends of platforms restrict speeds to 45 km/h through platforms. It may be possible if detailed survey were available, additional alignment design options may achieve a higher design speed. However, Essendon is a key node and therefore even if express services were introduced elsewhere on this line in the future, Essendon is unlikely to experience any significant express running. The 45 km/h curve speed restrictions will have negligible impact on train running times.

The results are shown on the plan entitled Buckley Street – Gas Main Locations with the main sizes derived from adjacent DBYD detail plans. In summary there are 100 mm and 225 mains on the south side of the road; the 225 mm main is continuous through the rail crossing, while the 100 mm main comes from the south in Sherbourne Road and turns to the west in Buckley Street. On the north side there is a 100 mm main continuous through the crossing and a proposed offtake main heading North on either the west side of railway reserve or the east side of Rose Street. Offsets are shown on the plan. The detail DBYD plans indicate that all existing mains are cast iron; the 225 main was constructed in 1918 and the 100 mains were installed in 1936. It is considered these mains would be reaching the end of the service life and will eventually be scheduled for replacement. This would need to be confirmed with SP Ausnet, the relevant gas authority for the region. It is recommended that discussions are initiated at an early date with the gas authority to investigate whether the gas main replacement can be undertaken in conjunction with rail regrading works, thus reducing the need for temporary connections on the existing mains when new mains are installed in the bridge understructure. As it is likely the bridge structure will comprise a series of super T’s or similar, the gas mains can be satisfactorily located in the void space between adjacent webs, in line with previous practices. The gas authority should be requested to provide advice on their requirements for accessibility to the gas mains. 130 | March 2015 | Essendon Junction Grade Separation, Draft Feasibility Assessment Report – Project No. 3132598 | GHD 100mm Prop Area Requested in DBYD Gas Distribution Mains GHD | Essendon Junction Grade Separation, Draft Feasibility Assessment Report – Project No. 3132598 | March 2015 | 131 Mt Alexander Road concept grading A concept gradeline has been prepared for Mt Alexander Road at the proposed rail under road grade separation using MGA 55 contour information. This indicates that a road surface level of approximately RL 44.00 can be graded into the existing surface level before the intersections immediately to the north and south of the rail corridor. This assumes a grade of 2% on the north western side and 1.6% on the south eastern side of the rail crossing estimated from available contour information. Based on this concept the vertical alignment of the road should allow sufficient sight distance to the back of queue in the event that the Shamrock Road intersection is signalised in the future. The vertical alignment of Mt Alexander road is heavily influenced by the rail design levels, clearance envelopes and depth of structure. As such, the road alignment should be considered as an integral part of subsequent design stages to ensure that an optimal outcome is achieved. 132 | March 2015 | Essendon Junction Grade Separation, Draft Feasibility Assessment Report – Project No. 3132598 | GHD MT ALEXANDER ROAD CH 188.000 TP CH 180.000 CH 160.000 CH 140.000 CH 120.000 CH 100.000 CH 80.000 CH 60.000 CH 40.000 CH 20.000 CH 0.000 TP PLAN IP CH 164.66 RL 42.67 RAIL CLEARANCE ENVELOPE RL 44.00 SAG CH 168.23 RL 42.82 IP CHCH 15.23 RLRL 42.94 SAG 13.27 43.11 IP CH 84.74 RL 44.75 CREST CH 84.74 RL 44.29 1:1000 VERTICAL SCALE 1:200 AT ORIGINAL SIZE 0 2 4 6m HORIZONTAL SCALE 1:1000 AT ORIGINAL SIZE 0 10 20 30m A CH 179.66 RL42.91 CH 149.66 RL43.06 CH 49.74 RL43.84 CH 30.23 RL43.33 CH 0.23 RL43.24 CH 119.74 RL43.84 PRELIMINARY rev PRELIMINARY ISSUE description app'd date ESSENDON STATION GRADE SEPARATION MT ALEXANDER ROAD CONCEPT GRADING DATUM RL. 35.00 L=0.23m L=19.51m K=6.52 L=30m L=29.92m K=13.46 L=70m L=8.34m 43.143 43.583 44.064 44.283 44.205 43.830 43.310 42.864 42.914 43.042 EXISTING SURFACE LEVEL 42.44 41.58 40.40 40.00 40.00 40.40 41.16 41.96 42.75 43.04 40.000 60.000 80.000 100.000 120.000 140.000 160.000 180.000 188.000 G=1.6% DESIGN SURFACE LEVEL CHAINAGE LONGITUDINAL SECTION HORIZONTAL SCALE 1:1000 VERTICAL SCALE 1:200 Plot Date: K=7.14 L=30m 20.000 G=-2.6% 43.244 G=2.6% 43.24 G=-2% 0.000 VERTICAL ALIGNMENT 18 February 2015 - 4:30 PM Plotted by: Tim James Cad File No: Level 8, 180 Lonsdale Street, Melbourne VIC 3000 Australia T 61 3 8687 8000 F 61 3 8687 8111 E [email protected] W www.ghd.com Conditions of Use: This document may only be used by GHD's client (and any other person who GHD has agreed can use this document) for the purpose for which it was prepared and must not be used by any other person or for any other purpose. scale 1:1000 date VERTICAL SCALE 1:200 AT ORIGINAL SIZE 0 2 4 6m HORIZONTAL SCALE 1:1000 AT ORIGINAL SIZE 0 10 20 30m FEB 2015 approved (PD) for A3 job no. 31-0919749 rev no.
