1 INTRODUCTION 1.1 BACKGROUND Wallbridge & Gilbert (W&G) have been engaged by the Town of Gawler (Council) to complete a review of the proposed Evanston Gardens Development Plan Amendment, and prepare a structure plan for the broader Evanston Gardens Area. The site, which covers approximately 100 ha, is located 5 km south west of the Gawler town centre, and approximately 40 km from the Adelaide CBD. The study area is bordered by Hillier Road / Gawler River to the north, Coventry Road to the south, Jack Cooper Drive to the east, and bya number of property boundaries to the west. The study area currently comprises existing residential allotments and rural land, as well as a local reserve and primary school. The area is also bordered by several other large land subdivisions, including Orleana Waters and Aspire. The majority of the land within the study area is currently zoned as Deferred Urban land, and has been identified for future residential development in The 30 Year Plan for Greater Adelaide. A proposal has been submitted to Council to amend the Development Plan and re-zone several allotments from Deferred Urban to Residential / Residential Park to allow for development of the land. A locality plan of the study area is illustrated in the following figure: Study Area Figure 1 - Proposed Land Division, Locality Plan 4 WALLBRIDGE & GILBERTEvanston Gardens Transport Infrastructure Review WAD151176 / Rev B INFRASTRUCTURE & ENVIRONMENTAL SERVICES Page 4 of 27

1.2 PURPOSE OF THE ASSESSMENT The purpose of this study is to identify the impact that the development of land within the study area will have on the existing transport infrastructure. The study will also identify any options/upgrades that may be required to ensure that the network can cope with any increase in traffic volumes. 1.3 PREVIOUS STUDIES The study will assess road infrastructure, as well as pedestrian and cyclist provision, and links to public transport. The following will be utilised while completing this study: Draft Gawler Transport and Traffic Management Plan, prepared by Mott MacDonald [July 2014] Draft Infrastructure Master Plan, New Southern Urban Areas (Evanston South, Evanston Gardens, Hillier), prepared by the Town of Gawler [August 2006] Standards and Requirements for Land Development/Land Division, prepared by the Town of Gawler [July 2012] Town of Gawler Development Plan, prepared by the Town of Gawler [April 2015] Gawler Community Plan 2014-2024, prepared by the Town of Gawler [September 2013] Strategic Directions Report 2013-2017, prepared by the Town of Gawler [July 2013] The methodology used in this analysis has been based on the Town of Gawler Development Plan, relevant Australian Standards and Austroads guidelines. 5 WALLBRIDGE & GILBERTEvanston Gardens Transport Infrastructure Review WAD151176 / Rev B INFRASTRUCTURE & ENVIRONMENTAL SERVICES Page 5 of 27

3 EXISTING 3.1 EXISTING CONDITIONS ROADWAY AND TRAFFIC CONDITIONS Currently the subject areas are typically undeveloped, with some existing residential properties and outbuildings. Roads that will be primarily impacted by development include: Hillier Road Angle Vale Road Jack Cooper Drive These roads will provide access to the major development areas and will experience increases in traffic volumes as a result of development. Key features of the roadways are discussed below. 3.1.1 HILLIER ROAD Hillier Road in the study area is a two-way, two lane local collector roadunder the care and control of Council. The road typically has unsealed shoulders along the length of the study area. Daily traffic volumes are estimated to be in the order of 1,000vehicles per day (vpd). The posted speed limit is 60 kph. 3.1.2 ANGLE VALE ROAD Angle Vale Road in the study area is a two-way, two lane arterialroadunder the care and control of thedepartment of Planning, Transport and Infrastructure (DPTI).The road typically has unsealed shoulders along the length of the study area. Average Annual Daily Traffic (AADT) volumes are in the order of 3,100 vehicles per day (vpd), with approximately 6% heavy vehicle traffic. The posted speed limit is 60 kph. 3.1.3 JACK COOPER DRIVE Jack Cooper Drive in the study area is a two-way, two lane arterial roadunder the care and control of DPTI.The road typically has sealed shoulders along the length of the study area. Average Annual Daily Traffic (AADT) volumes are in the order of 5,400 vehicles per day (vpd), with approximately 3.5% heavy vehicle traffic. The posted speed limit is 80 kph, reducing to 60kph south of the Hillier Road junction. 8 WALLBRIDGE & GILBERTEvanston Gardens Transport Infrastructure Review WAD151176 / Rev B INFRASTRUCTURE & ENVIRONMENTAL SERVICES Page 8 of 27

3.1.4 KEY INTERSECTIONS The key intersections within the study area are: Jack Cooper Drive / Hillier Roadpriority-controlled T-junction Angle Vale Road / Jack Cooper Drivepriority-controlled T-junction Angle Vale Road / Coventry Road priority-controlled T-junction 3.2 PLANNED ROADWAY IMPROVEMENTS It is understood that a new distributor road is under consideration to link Angle Vale Road and Coventry Road to Main North Road. It is anticipated that this roadway would be a key transit route for traffic generated within the study area, providing a more direct link to Adelaide and supplementing the existing major travel routes. 3.3 EXISTING PEDESTRIAN AND CYCLIST INFRASTRUCTURE Minimal footpaths or bicycle lanes are provided in the vicinity of the site on any of the key roadways within the study area. The exception is a short section of footpath on Angle vale Road, east of the Jack Cooper Drive junction. 3.4 EXISTING PUBLIC TRANSPORT INFRASTRUCTURE Bus stops are located on jack Cooper Drive, close to the Hillier Road and Angle Vale Road junctions. Services operate to and from Gawler. Tambelin Railway Station, on the Gawler line, is located approximately 1.5km from Hillier Road. Services operate to Adelaide city and Gawler. 9 WALLBRIDGE & GILBERTEvanston Gardens Transport Infrastructure Review WAD151176 / Rev B INFRASTRUCTURE & ENVIRONMENTAL SERVICES Page 9 of 27

4 TRAFFIC GENERATION AND DISTRIBUTION 4.1 DEVELOPMENT AREA TRIP GENERATION Traffic generation rates for the proposed development areas have focussed on the weekdaypm peak periods, as this is considered to be the critical period for residential developments. While developments within the study area will be constructed in stages, the analysis has focussed on the fully-completed scenario. RESIDENTIAL The specific breakdown of each development has not yet been finalised, so for the purposes of the analysis the following assumptions were applied: 12.5% of land area designated as green space 12.5% of land area designated as road reserve A rate of 25 allotments per hectare adopted, based on similar residential developments in the vicinity Residential traffic generation rates have been calculated based on thedraft Gawler Transport and Traffic Management Plan and the NSW Roads and Maritime Services(previously Road and Traffic Authority) Guide to Traffic Generating Developments, 2002. TheTransport and Traffic Management Plan specifies a traffic generation rate of 6.5 trips per unit per day. The Guide to Traffic Generating Developmentsspecifies a 10% peak hour factor for residential developments, which has been applied to the daily rate. Daily Trips 6.5 per dwelling PM Weekday Trips 0.65 per dwelling The calculated residential trip generation can also be separated into incoming and outgoing trips during peak periods. Based on the Institute of Transport Engineers Guide to Trip Generation 7 th Edition, the following ratios have been adopted: PM Peak Period 65% incoming and 35% outgoing NEIGHBOURHOOD CENTRE While it is anticipated that the neighbourhood centre will accommodate a variety of land uses, for the purposes of the analysis it has been assumed that the neighbourhood centre will primarily be retail. The following assumptions have been applied to the analysis: 10,000m 2 of the centre will be occupied by retail 35% (3,500m 2 ) of the retail area will be floor area. This proportion is based on typical standalone retail developments A supermarket land use was assumed, based on the ITE rate of 11.3 trips per 100m 2 GFA 10 WALLBRIDGE & GILBERTEvanston Gardens Transport Infrastructure Review WAD151176 / Rev B INFRASTRUCTURE & ENVIRONMENTAL SERVICES Page 10 of 27

KARBEETHAN RESERVE The reserve is not anticipated to be a large generator of trips during the PM peak. It would likely be a higher generator on weekends, when people would use the recreational facilities. EVANSTON GARDENS PRIMARY SCHOOL The primary school is an existing development and would not therefore generate any additional trips. 120 students are enrolled in the school. The trip rate of 0.28 per student has been adopted from the ITE Guide. Based on the above assumptions, the following table outlines the anticipated trip generation for the land division for the PM peak hour. While the school is an existing generator, it has been included due to its central location within the study area. Table 2: Proposed Development Area Peak Hour Traffic Generation Development Area Units Trip Rate Incoming Trips Outgoing Trips Total Trips Area 1 156 Allotments 0.65 per unit 65 35 100 Area 2 9.8 Hectares 0.02 per hectare 0 0 0 Area 3 7.9 Hectares 0.02 per hectare 0 0 0 Area 4 156 Allotments 0.65 per unit 20 10 30 Area 5 156 Allotments 0.65 per unit 135 75 210 Area 6 120 Students 0.28 per student 15 20 35 Area 7 3,500m 2 11.3 per 100m 2 200 200 400 Area 8 156 Allotments 0.65 per unit 125 65 190 Area 9 156 Allotments 0.2 per unit 20 10 30 Area 10 156 Allotments 0.65 per unit 30 45 45 Area 11 156 Allotments 0.65 per unit 15 5 20 Area 12 156 Allotments 0.65 per unit 5 5 10 Total New Trips 615 450 1,065 Total Study Area Trips 630 470 1,100 11 WALLBRIDGE & GILBERTEvanston Gardens Transport Infrastructure Review WAD151176 / Rev B INFRASTRUCTURE & ENVIRONMENTAL SERVICES Page 11 of 27

The use of the term Trip represents a one-way vehicular movement from one point to another but excluding the return journey. Therefore, a vehicle entering and leaving the development corresponds to two trips. The additional development-generated trips will be used to assess the performance of key site accesses and added to the road network to determine the impact of the proposed development on the local road network. A plan illustrating the anticipated traffic generation of each development area is included in Appendix B. 4.2 SPATIAL DISTRIBUTION OF TRIPS The distribution of trips throughout the local road network is influenced by the locations of the access points and the origins / destinations of trips on the external road network. Distribution will also be influenced by the new distributor road linking to Angle Vale Road, with a greater proportion of traffic travelling via the new road to Adelaide following its completion. In order to minimise the impact on the road network and improve safety, it is recommended that where possible access points are located away from arterial roads. It is also recommended that developments have one access point only, with traffic routed to the access via the internal development road network. The following table outlines the recommended locations for the development area access points: Table 3: Recommended Development Area Access Location Development Area Area 1 Area 2 Area 3 Area 4 Area 5 Area 6 Area 7 Area 8 Area 9 Area 10 Access Location Hillier Road Hillier Road & Angle Vale Road Hillier Road Angle Vale Road Angle Vale Road Hillier Road & Angle Vale Road Angle Vale Road Hillier Road & Angle Vale Road Hillier Road Murray Hillier Court Comments Existing road link through reserve. Potential to form an approach to new distributor road roundabout. Existing access points. Primary access via Angle Vale Road. Roundabout access recommended on Hillier Road, linking with existing retirement village / Area 9 access. T-junction access initially recommended on Angle Vale Road, to be upgraded to roundabout operation following realignment of Coventry Road Access via retirement village. Recommended roundabout link with Area 8 access. Murray Hillier Court junction with Jack Cooper Drive recommended for upgrade. 12 WALLBRIDGE & GILBERTEvanston Gardens Transport Infrastructure Review WAD151176 / Rev B INFRASTRUCTURE & ENVIRONMENTAL SERVICES Page 12 of 27

Development Area Area 11 Area 12 Access Location Murray Hillier Court Ross Davis Avenue Comments Murray Hillier Court junction with Jack Cooper Drive recommended for upgrade. Based on the proposed development area access locations, it is anticipated that the Jack Cooper Drive / Hillier Road junction (and Murray Hillier Court, should the junction be upgraded) will experience a significant increase in traffic volumes, with up to five residential development areas travelling via the junction. 4.3 TRIP ORIGIN / DESTINATION It is anticipated that Adelaide will be the primary destination for trips generated by the new development areas. Existing primary routes between the study area and Adelaide are: Via Jack Cooper Drive and Main North Road. 42km, estimated travel time 42 minutes Via Angle Vale Road and Northern Expressway. 43km, estimated travel time 39 minutes While travel via thenorthern Expressway is typically a faster route to Adelaide, it is anticipated that travel via Main North Road will experience a higher proportion of trips, as this route provides access to the northern suburbs. The route is also the primary route to Gawler. Should the proposed new distributor road progress, this will form an additional primary route: Via Angle Vale Road, the potential future distributor road and Main North Road. Estimated 37km,estimated travel time 40 minutes This route would draw traffic from both existing routes, with travel via Jack Cooper Drive anticipated to experience the highest decrease, as the new link will also connect to Main North Road. 13 WALLBRIDGE & GILBERTEvanston Gardens Transport Infrastructure Review WAD151176 / Rev B INFRASTRUCTURE & ENVIRONMENTAL SERVICES Page 13 of 27

5 INFRASTRUCTURE UPGRADES 5.1 INTERSECTION UPGRADE RECOMMENDATIONS As a consequence of the proposed development, it is recommended that a number of key affected intersections within the study area are upgraded. Upgrading the intersections will improve capacity, ensuring that the network can accommodate the projected increase in traffic volumes resulting from the proposed development. The upgrades will also aim to improve safety. The upgrading of junctions will be a staged process, with those immediately impacted by development upgraded first, with those experiencing a lesser impact being upgraded as required to accommodate projected demand. IMMEDIATE UPGRADE Hillier Road / Hillier Park Residential Village / Area 8 Access Road Hillier Road between Area 8 Access and Jack Cooper Drive Jack Cooper Drive / Hillier Road / Murray Hillier Court Area 8 Access Road / Angle Vale Road FUTURE UPGRADE Angle Vale Road / Jack Cooper Drive Angle Vale Road / Coventry Road Angle Vale Road / New Distributor Road Clifford Road / Area 9 Emergency Access A plan illustrating the recommended infrastructure upgrades is included in Appendix C. 5.2 HILLIER ROAD / HILLIER PARK RESIDENTIAL VILLAGE / AREA 8 ACCESS ROAD Access to Area 8 will be required during construction and once the first residential units are completed. Consequently it is recommended that the upgrades are implemented once construction commences on Area 8. It is recommended that the Area 8 access road is combined with the existing Hillier Park Residential Village access to form a new four-way intersection on Hillier Road. A roundabout treatment is recommended based on the following: Area 8 will be a major traffic generator, accounting for 50% of traffic at the intersection. A roundabout would provide greater capacity than a priority-controlled junction. It would minimise the number of access points on Hillier Road, benefitting safety. It would accommodate trips generated by Area 9, an expansion of the Residential Village. 14 WALLBRIDGE & GILBERTEvanston Gardens Transport Infrastructure Review WAD151176 / Rev B INFRASTRUCTURE & ENVIRONMENTAL SERVICES Page 14 of 27

COST OPINION Pre-Construction $70,000 Construction $410,000 Contingency 20% $120,000 Total $600,000 100% of cost to be borne by developer as access is required to service Area 8 and Area 9. 5.3 HILLIER ROAD BETWEEN AREA 8 ACCESS AND JACK COOPER DRIVE Hillier Road between the new Area 8 access and the Jack Cooper Drive junction will experience a significant increase in traffic volumes due to the development of Area 8 and Area 9. It is recommended that this section of Hillier Road is upgraded to accommodate the increased volumes and to improve safety. COST OPINION Pre-Construction $30,000 Construction $170,000 Contingency 20% $50,000 Total $250,000 100% of cost to be borne by developer due to increased volumes generated by Area 8 and Area 9. 5.4 JACK COOPER DRIVE / HILLIER ROAD / MURRAY HILLIER COURT The Jack Cooper Drive / Hillier Road junction is anticipated to be the junction most impacted by the proposed development. The majority of development-generated trips are anticipated to travel via this junction to Adelaide and Gawler. It is recommended that this junction is upgraded once work commences on the first of the development areas to accommodate the increase in traffic volumes and improve safety. It is recommended that the junction is upgraded to roundabout operation, with Murray Hillier Court rerouted to form a four-way intersection. This arrangementis recommended based on the following: The rerouting of Murray Hillier Court would reduce the number of junctions on Jack Cooper Drive, improving safety. The junction is anticipated to accommodate traffic from all development areas. A large number of right turn movements are anticipated between Jack Cooper Drive and Hillier Road, with the potential for queues and delays for right turning traffic. A roundabout would result in greater capacity and improved traffic operation and safety. COST OPINION Pre-Construction $120,000 Construction $680,000 Contingency 20% $200,000 Total $1,000,000 50% of cost to be borne by developer and 50% by others. Distribution is based on the projected traffic volumes generated by Area 8 and Area 9 compared to the existing and anticipated future traffic volumes utilising Murray Hillier Court. 15 WALLBRIDGE & GILBERTEvanston Gardens Transport Infrastructure Review WAD151176 / Rev B INFRASTRUCTURE & ENVIRONMENTAL SERVICES Page 15 of 27

5.5 AREA 8 ACCESS ROAD / ANGLE VALE ROAD In order to reduce the impact of Area 8 on Hillier Road and to provide greater connectivity to the south, it is recommended to include a secondary access to the south, linking to Angle Vale Road. As this would function as a secondary access, with lower volumes than the Hillier Road access, a priority-controlled T-junction is recommended. In the future, following the upgrade and realignment of the Angle Vale Road / Coventry Road junction, this junction will be upgraded to a four-arm roundabout. It will be necessary to maintain sufficient vacant area within Area 8 to allow for the future roundabout upgrade. COST OPINION Pre-Construction $40,000 Construction $200,000 Contingency 20% $60,000 Total $300,000 100% of cost to be borne by developer as access is required to service Area 8. 5.6 ANGLE VALE ROAD / JACK COOPER DRIVE A significant proportion of traffic from development areas with access roads on Angle Vale Road are anticipated to travel via the Angle Vale Road / Jack Cooper Drive junction. Additionally, a number of trips generated by the neighbourhood centre would travel via this junction. Upgrade to a roundabout is recommended to improve traffic operation at the junction. The existing alignment means that Angle Vale Road east is a major arm, despite being a small trip generator. Vehicles approaching on Jack Cooper Drive, a major trip generator, are consequently required to give way. A roundabout would improve traffic flow at the junction. COST OPINION Pre-Construction $140,000 Construction $820,000 Contingency 20% $240,000 Total $1,200,000 Upgrade subject to approval from DPTI. 5.7 ANGLE VALE ROAD / COVENTRY ROAD The anticipated increase in traffic volumes on Angle Vale Road, may lead to increased queuing and delays at the Angle Vale Road / Coventry Road junction for vehicles approaching on Coventry Road and right turning vehicles on Angle Vale Road. Upgrade to a roundabout would improve traffic operation at the junction, improving capacity and safety. It is recommended that the junction is realigned to the west, to provide greater separation to the Angle Vale Road / Jack Cooper Drive junction and to improve observation angles for traffic approaching on Coventry Road. The new roundabout would link to the Area 8 access, with the proposed T-junction upgraded to connect to the roundabout. As discussed above, it will be necessary to maintain sufficient vacant area within Area 8 to allow for the future roundabout upgrade. 16 WALLBRIDGE & GILBERTEvanston Gardens Transport Infrastructure Review WAD151176 / Rev B INFRASTRUCTURE & ENVIRONMENTAL SERVICES Page 16 of 27

COST OPINION Pre-Construction $140,000 Construction $820,000 Contingency 20% $240,000 Total $1,200,000 100% of cost to be borne by others. 5.8 ANGLE VALE ROAD / NEW DISTRIBUTOR ROAD Should development of the new distributor road proceed, it is recommended that a roundabout is installed at the new junction with Angle Vale Road. As all approaches are anticipated to accommodate high traffic volumes, a roundabout would offer superior operation and safety to a priority-controlled T-junction. COST OPINION Pre-Construction $140,000 Construction $820,000 Contingency 20% $240,000 Total $1,200,000 100% of cost to be borne by others. 5.9 CLIFFORD ROAD / AREA 9 EMERGENCY ACCESS It is noted that the existinghillier Park Residential Village access has been designed to encourage low speeds. It is recommended that an assessment is undertaken on the existing access to determine whether the arrangement is sufficient to accommodate the expanded retirement living development. If it is determined that the existing access does not have sufficient capacity to accommodate the additional trips, it is recommended that an emergency egress-only link is provided to Clifford Road. 5.10 PEDESTRIAN AND CYCLIST INFRASTRUCTURE As discussed previously, there is minimal existing pedestrian or cyclist infrastructure within the study area. It is recommended that a shared path network is constructed, linking key developments such as the school and neighbourhood centre to public transport services and large residential developments. 17 WALLBRIDGE & GILBERTEvanston Gardens Transport Infrastructure Review WAD151176 / Rev B INFRASTRUCTURE & ENVIRONMENTAL SERVICES Page 17 of 27

6 SUMMARY AND CONCLUSIONS Within the nominated study area in Evanston Gardens, up to 10 existing undeveloped areas may potentially be developed. Residential development is anticipated to account for the majority of land uses, with commercial and recreational land uses also possible. The new developments will result in additional trip generation, with the total generation for all development areas anticipated to be in the region of 10,000 trips per day and 1,000 trips during the weekday peak hours. The additional traffic generation will place increased demand on junctions withinthe study area. A number of upgrades are recommended to accommodate anticipated demand. Some upgrades are recommended for immediate implementation, while others are suitable for development in the future as more development areas are constructed. Junctions recommended for upgrade are: IMMEDIATE UPGRADE Hillier Road / Hillier Park Residential Village / Area 8 Access Road Roundabout operation Hillier Road between Area 8 Access and Jack Cooper Drive Midblock upgrade Jack Cooper Drive / Hillier Road / Murray Hillier Court Roundabout operation Area 8 Access Road / Angle Vale Road Priority-controlled T-junction FUTURE UPGRADE Angle Vale Road / Jack Cooper Drive Roundabout operation Angle Vale Road / Coventry Road Roundabout operation Angle Vale Road / New Distributor Road Roundabout operation Clifford Road / Area 9 Emergency Access (subject to assessment) It is considered that the future development areas can be satisfactorily accommodated subject to the upgrade of the above junctions. It is recommended that a shared path network is implemented to improve pedestrian and cyclist amenity and improve connectivity to the local public transport network. 18 WALLBRIDGE & GILBERTEvanston Gardens Transport Infrastructure Review WAD151176 / Rev B INFRASTRUCTURE & ENVIRONMENTAL SERVICES Page 18 of 27
