Stantec New Zealand Level 3, 111 Carlton Gore Road Newmarket, Auckland 1023 NEW ZEALAND Mail to: PO Box 13052, Christchurch 8141 1 July 2022 Project/File: 310203996 Environmental Protection Authority Dear Expert Consenting Panel, Reference: Waihoehoe Precinct This letter has been prepared in response to Minute 15 issued by the Expert Consenting Panel (the “Panel”) for the Waihoehoe Precinct Project (the “Project”). Specifically, it responds to the technical advice on transport and traffic provided to the Panel regarding the Project by Commute Transport Consultants, dated 27 June 2022 (“The Commute Letter”). Having reviewed this technical advice provided to the Panel, it is considered that the vast majority of potential issues identified and questions (certainly the most critical issues) that have arisen from the Panel are agreed and resolved or can be addressed by appropriate conditions of consent as suggested. The critical issues of agreement include: • The modelling demonstrates that restricting any development prior to the opening of the Rail Station is not required in relation to effects (item 3.3 of the Commute Letter); • The interim Waihoehoe Road layout is sufficient to cater for the expected traffic (item 5.1); • The roading / intersection upgrades provided within the conditions of consent are sufficient to accommodate the demands of the developments enabled by all three Drury East Fast Track applications (item 5.2 and 5.3); • The proposed cul-de-sacs offer sufficient active mode connections (albeit with a CPTED requirement discussed later in this letter) (item 5.4); • The overall roading layout is appropriate, albeit with several minor issues of detail (item 5.7); • The Ultimate Upgrade of Waihoehoe Road (east) is not required to provide sufficient active mode connection to the rail station (item 5.10); • The overall trip generation and modelling undertaken is appropriate (item 5.13); and • The proposed development aligns with relevant transport strategies (item 6.1). However, there are several issues that have been identified in the technical review by Commute which require further clarification / explanation. These are responded to within the body of this letter, or within Attachment 1 to this letter, which provides an additional comment column on the attachment within the Commute Letter. The key items dealt with within this letter are: • The concern relating to consent implementation difficulties at EPA stage for design issues not yet resolved at consent stage (item 3.2 of the Commute letter, and reiterated throughout); • The construction methodology for the Waihoehoe Rail Bridge (item 3.4); • The interim design treatment for the Waihoehoe Rail Bridge (also item 3.4); • CTMP Truck Routes (item 3.5); • Cul-de-sac designs and their shared path connections (items 5.4 and 5.5); • Roading layout / connections at the site boundary (items 5.7 and 5.8); • Vehicle tracking at key locations (item P3 of Attachment 1 of the Commute Letter); and • The level of detail provided for the proposed Waihoehoe Road / Road 16 intersection (item P20 of Attachment 1 of the Commute Letter). • Active Mode Facilities between Drury East and Drury South (item P58 of Attachment 1 of the Commute Letter).
1 July 2022 Page 2 of 42 Reference: Waihoehoe Precinct Each of these issues are addressed in detail within this letter. In addition, responses are also provided to each item within the Commute Memo Appendix (provided as Attachment 1 to this letter). 1 Consent Implementation Issues at EPA Stage. Item 3.2 and several further items refer to concerns relating to acquiring EPA for items where AT does not agree with the applicants’ design approach. This issue is dealt with in detail within the memo to the EPA dated 1 July 2022 prepared by the applicant’s counsel Mr Brabant (“Brabant Memo”). The Brabant Memo explains why a consent should not be withheld due to unresolved matters of detail that are better addressed at EPA stage. 2 Waihoehoe Road Bridge Interim Design Item 3.4 of the Commute Letter agrees that the Interim design is “the best and safest way of using the width available on the bridge (without widening / replacing / new walking and cycling bridge).” Comments were previously provided on this matter (Stantec Response Letter dated 13 April 2022), but for the sake of brevity were kept succinct. This section now seeks to expand upon earlier responses and discuss the matter in further detail. The over-arching response is that it is acknowledged that the design has shortfalls against TDM guidance, but when considering options available it is the best option available. 2.1 Current conditions The overbridge for Waihoehoe Road over the rail line to the Great South Road roundabout is currently one lane each direction, plus shoulders, and a narrow footpath on the northern side. The approximate width between railings is assumed as 10.4m to be conservative for design purposes at the fast-track application stage concept work. This current layout provides acceptable conditions for motor vehicles (to an acceptable level for the fast- track application traffic flows), but very low convenience and safety for people on bicycles and on foot. 2.2 Likely timing of permanent bridge replacement In the short-medium term, this overbridge requires a substantial rebuild, regardless of the Drury East Plan Changes or Fast Track applications. The main reasons for this are: o To allow the triple / quadruple-tracking of the North Island Main Trunk (NIMT) rail line. o To allow the additional traffic lanes as per the intended long term 30m wide Notice of Requirement arterial road layout and nearby intersection layout at Great South Road (to cater for flows beyond those of the current fast-track application area volumes) o To provide significantly improved walk and cycle facilities of a standard as per the intended long term 30m wide Notice of Requirement arterial road layout on Waihoehoe Road The indicative design within the NOR shows six traffic lanes over the rail line plus separated cycleways and footpaths on both sides of the road. It is acknowledged that the timing for the new rail overbridge is not yet confirmed, albeit it is understood as possible that an announcement on this may be made soon
1 July 2022 Page 3 of 42 Reference: Waihoehoe Precinct by authorities – potentially aimed at constructing the new bridge as part of the nearby Drury Central train station works by early 2025 1. Related to this, it is considered relevant that Waka Kotahi has, in February 2022 2, begun early works on replacing the three motorway rail overbridges over the NIMT, which includes moving the motorway alignment to the east, and providing for a future quadruple tracking. While these works, due to their extents, are expected to take until 2026/2027, they clearly show that quadruple tracking enabling works are already occurring – only 800m away. Also related to this is the fact that the electrification of the rail line to Pukekohe (also currently underway) is planned to be complete by the second half of 2024 3. Until then, the commuter functions of the NIMT to Pukekohe are undertaken by rail replacement buses. The lack of commuter trains, and the fact that any new lines are not yet electrified, mean it would be much easier to construct the new bridge in the short term. In summary, while no timeframes can yet be confirmed for the permanent overbridge replacement, it is likely that any interim layout as part of the fast-track application may quickly be superseded by the permanent layout. 2.3 Alternative Interim options considered In reviewing potential interim options for improving walking and cycling safety on the existing overbridge, the following alternative options were considered as part of the decision process to select the proposed interim upgrade presented in the fast-track application: o Option 1: Narrow cycle lanes (Option 1, Attachment 2) o By narrowing the current wide traffic lanes to only 3m each (feasible due to the straight alignment), it would be possible to add narrow cycle lanes and narrow separators (raised hard-rubber strips or similar) between the vehicle lanes and cycle lanes. o One cycle lane would be slightly wider (1.4m) than the other (1.2m), due to the fact that one lane (the westbound lane) would be directly adjacent to a railing. The existing ~1.2m wide footpath on the north side would be retained effectively as is. o While arguably safer for people on bikes than the current solution, it is considered that this option retains some significant issues. In particular, it would require departures from standards for narrow cycle lanes, narrow (and likely traversable) separators and sub-standard footpath width. The single footpaths would remain narrow albeit somewhat set back more from the cycle lanes. o The option also has narrow general lanes and would require a departure for these lane widths. o Overall, this option is considered feasible and safer than existing, but would provide limited improvement. o Option 2: Narrow shared paths (Option 2, Attachment 2) 1 https://at.govt.nz/about-us/news-events/end-of-the-line-in-sight-for-auckland-s-diesel-commuter-trains/ 2https://www.nzta.govt.nz/assets/projects/sh1-papakura-to-bombay/sh1-papakura-to-drury-project- update-april-2022.pdf 3 https://at.govt.nz/about-us/news-events/end-of-the-line-in-sight-for-auckland-s-diesel-commuter-trains/
1 July 2022 Page 4 of 42 Reference: Waihoehoe Precinct o In this option, as per Option 1, the traffic lanes are narrowed, but the achieved width is instead allocated to provide two narrow shared paths on each side. This would provide 3.2m wide lanes (with 0.2m channel allowance) and 2.0m wide shared paths each side. o This option would provide walking and cycling facilities on both sides of the bridge, reducing the need for people to cross the road to a single-sided facility. o However, pedestrians would have to share with people on bicycles for over at least 25m-30m distance, in a narrow path environment. At 2m width this is lower than the 2.5m absolute minimum of the Transport Design Manual, which also is to be used only over a shorter distance of 15m length. o With traffic and substantial heavy vehicle flows directly adjacent to these narrow shared paths, this option was not considered safe enough to proceed with. o Option 3: Standard shared path (Option 3, Attachment 2) o In this option, as per Option 1 and 2, the traffic lanes are narrowed, but the achieved width is instead mostly allocated to provide a single 3.0m width shared path on one side (south side in the fast-track application plans). o This would provide an effective 3.2m wide lane in westbound direction (including the channel on the shared path kerb side), a 3.0m wide lane on the non-shared path eastbound side, and a 1.2m marked eastbound shoulder. o The key advantages of this solution would be that it would provide a wider shared path solution, and also create less constrained general traffic lanes. o For these reasons, and because other options discussed below were not deemed appropriate, Option 3 was taken forward to the application. o Option 4: Separate walk/cycle bridge (not shown) o It was considered whether a separate, adjacent interim walk/cycle bridge would be suitable to cater for the active mode facilities. This was quickly identified as having significant costs and challenges. o If constructed to two-track width, it would still require a sizable span width of some 25m or more. If constructed to future four-track width, this would increase costs further, especially if KiwiRail opposed central supports. o Unlike the works on top of the existing bridge in Option 1-3, the new bridge would require much more extensive works, above a live rail line. This is because freight trains and commuter trains to Hamilton are still using the NIMT even while the commuter connection to Pukekohe is suspended. o Depending on timeframes, from late 2024, the line to be spanned would also be electrified. Even if the works occurred before the lines went live, the new bridge would have to be built with modern added clearances and protections for the users against proximity to electrical lines. o If constructed, a new bridge would represent a major work in the same timeline and in close proximity to a major train station / interchange project nearby, increasing complexity of approvals and works. o If constructed over the current two-track rail line width, it would need to be removed as soon as the four-tracking project occurs. o If constructed close to the existing bridge, it would likely need to be removed as soon as the new overbridge is constructed, as it would be expected to clash with the work zones or new structures. o If constructed both to future four-tracking widths and further away from the existing bridge, it would be out of line for the use by Waihoehoe Road active mode users - and also require 3rd party land acquisition because it will extend beyond the existing road corridor. This then presents the challenge of feasible physical implementation because
1 July 2022 Page 5 of 42 Reference: Waihoehoe Precinct it would require land that is not owned or controlled by any of the Drury East developers (i.e. Kiwi Property, Fulton Hogan and Oyster Capital). o As noted above, the close proximity in space and time to various major infrastructure works in the area (quadruple-tracking, new train station, new overbridge) may also mean that in practice, the further (post-fast-track) approvals of such a new bridge would be difficult and uncertain. o In Commute’s 27 June 2022 memorandum, the risk is raised that the application layout, if not favoured by Auckland Transport, might be rejected at EPA, leading to an unimplementable consent. Arguably, the same applies even more to a new bridge in these constrained circumstances. o If despite all the above constraints, a feasible location can be found and approval from the various parties, including KiwiRail, be achieved, the resulting structure will be significantly more complex and costly compared to a “simple” walk/cycle bridge say, bridging a stream. o Considering the lifetime of the new bridge might well be measured in a handful of years, this option was discarded as unreasonable. o Option 5: Clip on widening to bridge (not shown) o It was also considered whether it would be feasible to attach a “clip-on” structure to the existing bridge to provide additional space for walk / cycle facilities, easing the constraints experienced by the above options. o Any cantilevered structure, even if only supporting active modes, can place significant strain on existing support structures of an aging bridge. This potential issue increases with width and length of the facility. o It is therefore considered likely that any substantial-width clip-on, even if not effectively needing to be designed as a new bridge, would still incur many of the costs and downsides of Option 4, for less active mode benefit – and no greater certainty of being in place for longer. As such, this option was also discarded. 2.4 Other factors / responses in support of the application interim layout Structural concerns regarding location of shared path: Among other aspects, concerns have been raised in Commute’s 27 June 2022 memorandum regarding the structural feasibility of removing the current northern-side footpath, replacing it with a trafficable shoulder and adding the interim shared path on the south side. These concerns are acknowledged, as the required structural assessment has not yet taken place. o However, it is noted that if, on further structural assessment, this concern is realised, the interim layout proposed can feasibly be mirrored, with the shared path located on the north side. o While this change (if later found to be required) would place the shared path on the bridge on the opposite side from the shared path for the rest of the fast-track interim design for Waihoehoe Road to the east, there is sufficient space in the immediate bridge vicinity to the west and east to place the shared path on the north side. o This crossing location to the onward shared path eastwards on Waihoehoe Road could be at a mid-block location, or, possibly more suitably, cross to the south side at the new train station intersection at Kath Henry Lane. As such, this concern if it eventuates, would not make the overall concept unfeasible.
1 July 2022 Page 6 of 42 Reference: Waihoehoe Precinct Concern over proximity of shared path users to live lane Concerns have been raised in Commute’s 27 June 2022 memorandum, and by AT, about the proximity of the proposed 3.0m wide interim shared path to a live lane. It is considered that while not ideal, this is actually a very common situation across Auckland – and thus acceptable for a temporary interim solution. It is also noted that where providing retrofit facilities, or changes to existing roads and intersections, Auckland Transport and Waka Kotahi also continue to occasionally approve and construct shared paths immediately adjacent to live lanes – citing constraints in space and funding, even where no clear path to later upgrade is available. The most prominent Auckland examples of existing shared paths adjacent to live lanes are both on the Tamaki Drive shared path, at Ngapipi Bridge (near Ngapipi Road intersection) and opposite The Strand. This existing shared path on the Ngapipi Bridge is of similar width as the fast-track interim proposal (approximately 3.0m) – but the section located directly adjacent (no buffer zone, railing or crash barrier) is much longer, at approximately 90m instead of 30m. Likewise, on the northern side of Tamaki Drive opposite The Strand, a 60m long section of the shared path that connects two stretches of separated cycleways / footpaths narrows to 3m and is adjacent to the live lanes. Figure 1: Street View of Tamaki Drive Shared Path over Ngapipi Bridge
1 July 2022 Page 7 of 42 Reference: Waihoehoe Precinct Figure 2: Tamaki Drive shared path adjacent to the Strand Tamaki Drive is Auckland’s busiest cycle route, with, regular daily numbers of more than 1,000 users, and on some days, more than 2,000 riders. The adjacent traffic lanes of the arterial road carry approximately 18,000 vehicles per day (at Ngapipi Bridge). As such, the situation is highly comparable – except that the active mode user demand on Waihoehoe Road will be significantly lower, reducing the likelihood of conflict on the path. Despite this existing situation being in place on Tamaki Drive for nearly 50 years (the facility has been a legal shared facility since 1976), the applicant is not aware of any safety issues related to this bridge shared path adjacent to the traffic lanes. It is acknowledged that Auckland Transport has a project in the works to add an active mode bridge adjacent to the existing Tamaki Drive Ngapipi Drive facility, which will in the coming years reduce or remove the downsides of the shared path, however, the design also does not have a buffer to live traffic lanes. Therefore, providing a similar facility on a much less busy active mode route, when there is an imminent future upgrade, is considered appropriate. Low demand levels, further reduced One of the key concerns regarding a shared path is the potential for conflicts of users, and thus the risk of this leading to a user accidentally entering the adjacent traffic lane. This clearly is highly dependent on the level of use of the path. It is considered that the section of path on the rail bridge will not see very high use, as current origins and destinations are still limited. Crucially in this regard, the main future pedestrian origin/destination in the area, the coming Drury Central train station, will have its own rail overbridge, and an entrance off Great South Road. This allows access from both sides of the rail line (and depending on possession of a HOP card / gating arrangement, may even allow “through trips” through the station for people not catching a train or bus).
1 July 2022 Page 8 of 42 Reference: Waihoehoe Precinct In a local context, this will mean that many pedestrian users of the station who would otherwise use the new shared path on the rail overbridge will find the station’s own overbridge much more convenient, reducing interim usage on Waihoehoe Road, and thus any conflicts. Potential railing addition (as per Option 3a, Attachment 2) As discussed in the above and in the application, the proposed 3.0m shared path complies with Auckland Transport’s minimum width – the issues raised appear to be largely with the lack of separation from the traffic lanes (normally, a shared path is to be located 1m or more away from the live lane according to Auckland Transport’s guidance). While in the constrained situation found on the existing bridge, adding this separation is not feasible, a potential change to the application design would be to provide a heavy-duty pedestrian fence between the shared path and the live lanes. This would require approximately 0.4m width (nominal railing width allowance of 0.1m width, and 0.3m setback from the kerb). While this railing design would constrain the remaining path to 2.6m width, such a railing would result in a facility that would significantly reduce the remnant risk of any active mode user accidentally entering the live traffic lanes. With the comments above regarding likely low patronage, and the interim nature of the facility, it is considered that this adjustment would provide a way forward to overcome the key concern raised. 2.5 Rail Bridge Interim Design Conclusion Given the above discussion, the following conclusions are evident: • The proposed interim design will represent a shortfall against TDM, but will provide a safe and convenient solution in the interim until the full bridge upgrade is provide as per the NOR design; • There are examples of other interim designs in Auckland that have similar TDM departures, but have significantly higher active mode and traffic demand; • The alternatives considered are considered either inadequate or too complex from a constructability / disruption perspective. As such, the proposed interim design is considered the most pragmatic and effective approach. 3 Waihoehoe Road Bridge Construction Methodology Item 3.4 of The Commute Letter discusses the construction of the Ultimate upgrade to Waihoehoe Road Rail Bridge in the future that is enabled by the NOR, including the following excerpt: “This upgrade requires substantial regrading of Waihoehoe Road, on both sides of the bridge. The plans within the NoR shows the height difference between the existing and final carriageway level, being up to 4.23 metres. This is likely to result in significant challenges in keeping Waihoehoe Road open to traffic (especially in two directions) during construction. As a result, it is likely that when this upgrade occurs in the future, access to the subject site will be restricted to Fitzgerald Road.” It is acknowledged that upgrading an existing road corridor and bridge whilst retaining current use is an aspect that requires consideration. However, this issue is best dealt with at EPA stage (of the Ultimate upgrade works) when construction methodologies are known.
1 July 2022 Page 9 of 42 Reference: Waihoehoe Precinct There are many excellent examples of construction methodologies that have overcome such constraints on much busier transport corridors. One recent example is the Eastern Busway between Panmure and Pakuranga. As with Waihoehoe Road, the Pakuranga Road corridor and its new bridge were both constructed alongside the existing corridor and bridge, then a series of contra-flow traffic management systems minimised traffic disruption as the old and new sections were completed. As in this case, the new Panmure Bridge is also several metres higher than the old bridge (which has remained). A similar methodology is feasible for this project, especially as the NOR widens the corridor at only one side of the road, which enables such lane flexibility used at the Eastern Busway. 4 Construction Traffic Management Plan Item 3.5 of the Commute Letter requests truck routes, which were not provided within the Outline CTMP provided with the ITA. The truck route for this site will be Waihoehoe Road (west), Great South Road, State Highway 1. Given the response in Section 3 of this letter, it is anticipated that careful construction methodology of the future Waihoehoe Rail Bridge construction can adequately ensure that this route will always be available. For minor road closures that may be required, these are anticipated to be overnight only. However, in the unlikely event that a brief daytime closure of Waihoehoe Road rail bridge is required, then trucks will use the Fitzgerald Road to Quarry Road, then travel to SH1 via Maketu Road (via the Ramarama Interchange) or Great South Road, SH22 (via the Drury Interchange). As these routes are already used for construction and earthworks traffic as part of the Drury South development, no issues with regard to safety or capacity are expected. The Commute Letter also recommends a change to the CTMP condition to ensure integration with other construction projects within Drury. This change is acceptable and has been included in the revised conditions. 5 Cul-de-sac / Shared Path Designs Items 5.4 – 5.6 of the Commute Letter discuss the proposed cul-de-sacs and the shared path connects at each head. Overall, Commute agrees that cul-de-sacs are an appropriate layout if they have appropriate active mode connections. However, Commute concurs with AT that a CPTED assessment is required to justify the departure from standard required to reduce the overall corridor width from 8m to 5m. This CPTED Assessment has been undertaken and is provided under separate cover by Barker & Associates. 6 Roading Layout at Site Boundaries Items 5.7 and 5.8 of the Commute Letter suggests that any roads that stop adjacent to neighbouring land should be provided / formed right up to the boundary. This request is acceptable, and a condition of consent is proposed to this effect.
1 July 2022 Page 10 of 42 Reference: Waihoehoe Precinct 7 Vehicle Tracking at Key Locations Item P3 of Attachment 1 of the Commute Letter requests additional vehicle tracking to demonstrate compliance, particularly around 90deg curves. Additional tracking for the 90-degree curves has been provided (all four parts of Sheet 1, and the top two parts of Sheet 2 of Attachment 3). It is acknowledged that the tracking shown for these 90-degree curves do not meet the “mid-block” requirements of passing between a van and a rubbish truck. This is because functionally, they perform, and have similar sizing to a small, compact residential intersection (where rubbish trucks are not assumed to have to be able to turn at the same time as another vehicle coming out of the 90-degree adjoining road). Such tight local road curves are common throughout Auckland, and these in fact assist with traffic calming / slow speed environments (tight curves are explicitly noted as traffic calming features in the relevant sections of the TDM). As long as sightlines are appropriate for such a slower- speed low-volume environment (which they are), drivers will naturally negotiate giving way to (or be given way by) a rubbish truck passing the other way. Designing these as full curves would follow a more “mid-block” logic that would require road widening and encourage speeds not considered appropriate for these locations. It is also acknowledged that several of the vehicle tracks shown overlap with kerblines etc. This merely reflects the level of detail that is necessary at resource consent stage, as opposed to EPA stage. For EPA, any remaining minor changes to accommodate the tracking will be undertaken alongside incorporation of other comments received as part of the AT consultation at that time. Modifying the designs at resource consent stage to accommodate the tracking only to make further changes at EPA stage is inefficient. 8 Waihoehoe Road / Road 16 Intersection Item P20 of Attachment 1 of the Commute Letter requests further information regarding the design of the Waihoehoe Road / Road 16 intersection. Additional information / refinement of this signalised layout, and associated vehicle tracking, is now provided in Attachment 4 of this letter. The plans also show visibility checks to the two zebra crossings. For the eastbound approach on Waihoehoe Road to the western zebra crossing, we have reviewed this initially for 70 kph (the current speed limit of Waihoehoe Road) and also for 50kph, which we consider more appropriate for this location, even with the current condition. The latter is because a driver approaching this intersection and turning left is going to be highly conscious that this is an intersection (not a left-turn free-flow curve). Factors in this regard are the presence of an upcoming median island including a slight left deflection of the through lane, the presence of traffic signal poles, the raised-table zebra visible ahead left, and the relatively tight curve (sized for 10.3m rubbish trucks, i.e. for local road conditions). In practice, this slip lane will function very similar to any raised zebra crossing slip lane in a signal. With the added physical reinforcement of the raised table, practical crossing speeds will be more likely to be around 30 kph. However, crucially, even the 70 kph sightline requirement can be met, assuming no obstructions are located in the sightline where it passes outside the current road corridor. The applicant is willing to agree to a consent condition keeping this sightline clear - and it is important to note that this sightline passes through area that the NOR intends for road widening, i.e. will not be developed in any case.
1 July 2022 Page 11 of 42 Reference: Waihoehoe Precinct For the approach from the north on Road 16, we have assumed a 30kph speed environment (and formal speed limit), as this will be a very narrow local road, with traffic calming as required on all local roads. The required sightlines are met. Reaction time chosen was 2.0s instead of 2.5s even for the Waihoehoe Road approach, which in the near-term future could still be considered rural. This is because the conflict only occurs if the driver voluntarily steers left into the side road, i.e. it can be considered that the driver is at normal alert state, rather than less alert as might occur on a straight-through rural road approach to a mid-block crossing. The plans now also show key dimensions, some minor road marking additions (limit lines, give way triangles etc), and the proposed traffic signal pole locations. For clarification, as the path on the south side of Waihoehoe Road is a shared path, and as Road 16 is a local road, the crossing has been shown as a wide pedestrian crossing, but this could alternatively be a split walk/cycle crossing. 9 Active Mode Facilities between Drury East and Drury South Item P58 of Attachment 1 of the Commute Letter raises a minor concern regarding upgrades between Drury East developments and Drury South. It is acknowledged that the project does not provide additional active mode upgrades south of any other Drury East Fast Track development connections. This is considered to not be necessary for several reasons: • The proposed development, and the overall upgrades outlined in Plan Changes 48, 49 and 50 focus almost all journeys towards the now consented Drury Central train station, the metropolitan centre to continue north linking to the train station, the other Drury East Plan Change 4 areas and associated Fast Track development proposals, and the external street network via Waihoehoe Road. The traffic modelling established that the vast majority of the demand will be to those destinations, and only a relatively small number of trips (by all modes) will be made to the south; • There is an existing shared pathway provided along Waihoehoe Road and Drury Hills Road that provides an active mode connection between Drury East and Drury South. Although it may necessitate journey diversions, it does represent an unbroken active mode connection should some users prefer to use that route; • It is considered that connecting this project, and the wider Drury East Plan Changes (48, 49 and 50) to the closest development area in Drury South is unnecessary and beyond the scope of mitigation required for this project; • It is anticipated that as part of Plan Change 49, further active mode upgrades on Fitzgerald Road to the south of Brookfield Road will be provided as part of subsequent resource consent stages. That Plan Change’s precinct provisions ensure that any development fronting any of the collector roads needs to provide active mode upgrades towards the train station and Waihoehoe Road. So as ongoing resource consent or Fast Track applications are submitted that front Fitzgerald Road, the upgrades will move further south; 4 Private Plan Changes 48 and 49.
1 July 2022 Page 12 of 42 Reference: Waihoehoe Precinct • It is anticipated that as Drury East continues to urbanise as anticipated and planned for within the Council’s Drury-Opaheke Structure Plan with future subsequent plan change applications to rezone the remaining Future Urban zoned land between Drury East and Drury South that will appropriately address active mode connections between the two destinations; and • By way of background and during caucusing for the Drury East Plan Changes, Council’s consultant traffic engineer (in their capacity as regulator) also queried if active mode connections to the south should be provided. This was addressed within the plan change hearing evidence for the Drury East plan change applicants that upgrades south of the plan change areas were outside of the plan changes mitigation remit. The Hearing Panel agree, and the Panel’s decision found in favour of the applicants– i.e the requested addition by Council to include upgrades to the south within the transport upgrade standard were rejected. As such, it is considered that the request for additional active mode connections on Fitzgerald Road to the south of the Drury East Fast Track Applications are unjustified and unwarranted for the mitigation of any adverse effects arising from this project.

This can be overcome by providing active mode road to road links (i.e. shared paths/accessways) but they need to be designed correctly.

Treating these as per the design requirements of the TDM). separated paths implies that the user would actually separate themselves to the appropriate side, which given the short length, is unlikely given the short desire line. In this context, providing a separated path would simply overcomplicate things, particularly at the ends, where the separated cycleway would then need a give-way (potentially raised) crossing over the footpath. The safety impacts of shared paths relate to two key issues - sightlines and the path level of use. By virtue of (relatively wide) corridors and open, right-angle intersections, the first is avoided, and the second is not going to be an issue because these are not through routes, they are the lowest level of dispersed use by bike riders, rather than a "collector" cycle element or similar.

Auckland Transport does not accept the vesting of ‘paper roads’. These connections are deemed important to ensure that future east-west connections are enabled by the current consent application. This is particularly important in the absence of an approved Precinct Plan under the plan change process that would better define the roading layout for future developers

This has the potential to create more than minor (and potentially significant) future operational and safety effects on Waihoehoe Road.

It is therefore not a question of replacing like for like as the standard of pavement needs to be to an urban standard capable of withstanding this traffic and the subsequent increases in traffic associated with completed development.

Non-compliance with AT’s TDM and provision of appropriate urban linkages to the development site will cause a fragmented transport network and less than desirable outcome. Accordingly, it is considered necessary that any future development in Drury will be, from the early stages of development, well connected to the Drury Central Rail Station (now consented) thus having effective and efficient public transport facilities integrated with safe walking and cycling infrastructure. Based on the details supplied with this application, I remain concerned that there will be gaps or substandard links in the infrastructure which is required to enable and encourage active modal travel to and from the Drury Central Rail Station.
