1. INTRODUCTION
1.1 Scope of Assessment Stanbury Traffic Planning has been commissioned by Two Visions Pty. Ltd. to prepare a Traffic & Parking Impact Assessment to accompany a Development Application to be lodged with Blacktown City Council. The Development Application seeks consent for the demolition of three existing detached dwellings and the construction of a residential apartment development containing 40 dwellings at 13 – 17 Oxford Street, Blacktown (hereafter referred to as the ‘subject site’). This aim of this assessment is to investigate and report upon the potential traffic and parking consequences of the development application and to recommend appropriate ameliorative measures where required. This report provides the following scope of assessment:
Section 1 provides a summary of the site location, details, existing and surrounding land‐uses;
Section 2 describes the proposed development;
Section 3 assesses the adequacy of the proposed site access arrangements, parking provision, internal circulation and servicing arrangements with reference to relevant Council, Roads & Maritime Services and Australian Standard specifications;
Section 4 assesses the existing traffic, parking and transport conditions surrounding and servicing the subject development site including a description of the surrounding road network, traffic demands, operational performance and available public transport infrastructure; and
Section 5 estimates the projected traffic generating ability of the proposed development and assesses the ability or otherwise of the surrounding road network to be capable of accommodating the altered demand in a safe and efficient manner.
The report has been prepared pursuant to State Environmental Planning Policy (Infrastructure) 2007. The application is not of sufficient scale to be referred to the Roads & Maritime Services under this Instrument.

2. PROPOSED DEVELOPMENT
2.1 Built Form
The subject application seeks Council’s approval to demolish three existing detached dwellings and the construction of a residential apartment development comprising a total of 40 dwellings, made up of the following:
7 one bedroom dwellings;
31 two bedroom dwellings; and
2 three bedroom dwellings. The dwellings are proposed to be contained within a single six storey building located approximately central to the site. The development is to be serviced by two levels of basement passenger vehicle parking accommodating 63 parking spaces (including one car wash bay), 10 bicycle parking spaces and four motorbike spaces. Access between this parking area and Oxford Street is proposed via a single combined ingress / egress driveway located within the south‐western corner of the site. Pedestrian access is proposed to Oxford Street, separate and to the north of the abovementioned vehicular access driveway.

3. SITE ACCESS & INTERNAL CIRCULATION
3.1 Passenger Vehicular Access
Vehicular access between the development and Oxford Street is proposed to be provided via a 6m wide combined ingress / egress driveway located within the south‐western corner of the site. The above driveway arrangement is proposed to provide direct connectivity to an internal roadway running along the southern site boundary, linking with a formalised at‐grade loading dock and a ramp connecting to two levels of basement car parking. AS2890.1:2004 provides driveway design specifications based on the proposed primary land use, the functional order of the access road and the number of spaces the driveway is to serve. Tables 3.1 and 3.2 of AS2890.1:2004 specify that, at minimum, a Category 1 type driveway is required, providing a combined ingress / egress driveway width of between 3m and 5.5m based on the local functional order of Oxford Street, the residential land‐use and the passenger vehicle parking provision within the basement parking area of 62 spaces. The proposed combined ingress / egress driveway width of 6m therefore complies with the minimum AS2890.1‐2004 specifications and accordingly is considered to be satisfactory. Further to the above swept path plans have been prepared in order to demonstrate the ability of passenger vehicles to enter and exit the site in combination, copies of which are included as Appendix 2. The safety and efficiency of access / egress movements are also proposed to be assisted by the provision of a relatively level grade within the first 6m inside the property boundary. It is further noted that sight distance between exiting vehicles and Oxford Street are not proposed to be impeded by any obstructions along the site frontage, suitably according with the requirements of Figure 3.3 of AS2890.1:2004. Oxford Street provides a consistent vertical and horizontal alignment within the vicinity of the subject site, resulting in good sight distance between the frontage road and the proposed site access driveway.
3.2 Service Vehicle Access
BDCP 2015 states the following where internal collections are provided: (a) Access to the garbage and recycling collection points by service vehicles will
require that there be a minimum height clearance for internal garbage areas sufficient to meet operational heights of collection vehicles. The radius and curvature of internal roads and ramps must be free of obstruction to State Government standards.
Stanbury Traffic Planning Page
Oxford Street, Blacktown 17-046
10
(b) Collection vehicles should not be in the position that they obstruct access or egress by other vehicles and consideration must be made for contractors who may have additional requirements to facilitate collection.
(c) The owner/s of the building must, prior to collection services commencing,
indemnify Council against any damage to the building caused by the collection of garbage, recyclables or waste by Council vehicles, or contractors acting on behalf of Council, unless such damage is caused by an act of negligence by the collection operator.
(d) A positive covenant and/or easement is to be created under Section 88B of
the Conveyancing Act 1919 over that portion of the driveway shared by resident and garbage collection vehicles. It is to be structurally designed by a chartered professional engineer to a length of no less than 10 metres, a width of no less than 5 metres and to withstand a load of 25.5 tonnes to accommodate garbage trucks.
(e) Where on‐site collections are provided, provision must be made for safe
manoeuvring of the vehicle on the site and egress and access should be in a forward direction.
The previously presented site access driveway is proposed to provide direct connectivity to an internal roadway running along the southern site boundary, thence linking with a formalised internal loading bay, capable of accommodating refuse collection vehicles with a length consistent with a Medium Rigid Vehicle (MRV) and smaller removalist. Service vehicles are proposed to directly access the servicing bay by entering the development site in a forward direction and thence reversing into the bay. Following the completion of the required loading / unloading activates, service vehicles are proposed to exit the bay and site via a simple forward manoeuvre. Swept path plans have been prepared in order to demonstrate the ability of vehicles up to and including MRVs to enter and exit the on‐site servicing area as described, copies of which are included in Appendix 2.
3.3 Parking Provision 3.3.1 Vehicular Parking Provision
The development is serviced by a total of 63 off‐street passenger vehicle parking spaces provided as follows: Basement level 1 Resident spaces 13 Adaptable 2 Visitor spaces 16 Car wash spaces 1
Stanbury Traffic Planning Page
Oxford Street, Blacktown 17-046
11
Basement level 2 Resident spaces 29 Adaptable 2 Total 63 spaces
3.3.2 Council’s Vehicular Parking Requirements
Blacktown Council specifies the following off‐street parking rates for Residential Flat buildings: 1 space per 1 or 2 bedroom dwelling 2 spaces per 3 or more bedroom dwelling 1 visitor space per dwelling or part thereof Table 1 identifies the off‐street parking required to satisfy Blacktown Development Control Plan 2015.
TABLE 1 OFF‐STREET PARKING REQUIREMENTS
BLACKTOWN DEVELOPMENT ONTROL PLAN 2015 Measure No. Dwellings Spaces Required
1 bedroom 7 7
2 bedroom 31 31
3 bedroom 2 4
Visitor/dwelling 40 16
Total 58
Based on the parking rates of DCP 2015, the proposed development requires a minimum of 58 off‐street parking spaces, comprising 40 resident and 16 visitors. The proposed parking provision of 42 resident, 16 visitor and 1 car wash bay therefore complies with the relevant DCP 2015 requirements.
3.3.3 Bicycle Parking
Blacktown DCP 2015 has no requirement to provide bicycle parking. The subject development is to provide 10 bicycle storage racks on the basement level 2 areas.
3.3.4 Motorcycle Parking
Blacktown DCP 2015 has no requirement to provide Motorcycle Parking. The subject development is to provide four motorcycle parking spots on basement level two.
Stanbury Traffic Planning Page
Oxford Street, Blacktown 17-046

3.4 Internal Circulation and Manoeuvrability 3.4.1 Site Access Ramp
The ramps connecting the internal at‐grade and the basement levels have been designed to provide grades in accordance with the relevant requirements of AS2890.1:2004, providing the following characteristics:
Maximum ramp grade = 1 in 4;
Maximum change in grade = 1 in 8; and
Maximum ramp grade for the first 6m inside the site = 1 in 20. The proposed internal ramp designs are therefore considered to be satisfactory.
3.4.2 Basement Car Park
Upon entry into the access driveway, passenger vehicles will proceed in a forward direction to access the basement parking levels via a ramp running approximately central to the eastern site boundary. An intercom is proposed to govern vehicular access to the basement parking area at the top of the access ramp. Passenger vehicle parking spaces within the basement parking area comprise a series of standard 90 degree angled rows of spaces serviced by adjoining parking aisles. The basement parking area has been designed to accord with the requirements of AS2890.1:2004 and AS2890.6:2009, providing the following minimum characteristics:
Standard vehicular parking space width = 2.4m;
Disabled vehicular parking space width = 2.4m (with adjoining 2.4m wide shared area provided within manoeuvring aisle);
Additional vehicular space width where parking spaces adjoins an obstruction = 0.3m;
Standard and disabled vehicular parking space length = 5.4m;
Vehicular parking aisle width adjoining parking spaces = 5.8m;
Headroom = 2.2m;
Headroom above disabled parking spaces and adjoining shared areas = 2.5m; and
Parking aisle extension past dead end parking bays = 1m. Safe and efficient internal manoeuvring and parking space accessibility is anticipated to result, taking into consideration the above compliance with the relevant AS2890.1:2004 and AS2890.6:2009 specifications.

In order to demonstrate the internal passenger vehicle manoeuvrability within the vicinity of these areas and generally throughout the overall parking area, this Practice has prepared a number of swept path plans which are included as Appendix 2. The turning paths provided on the plans have been generated using Autoturn software and derived from B99 and B85 vehicle specifications provided within AS2890.1:2004. Section B4.4 of AS2890.1:2004 states the following with regard to the use of templates to assess vehicle manoeuvring: ‘Constant radius swept turning paths, based on the design vehicle’s minimum turning circle are not suitable for determining the aisle width needed for manoeuvring into and out of parking spaces. Drivers can manoeuvre vehicles within smaller spaces than swept turning paths would suggest.’ It would therefore appear that whilst the turning paths provided within AS2890.1:2004 can be utilised to provide a ‘general indication’ of the suitability or otherwise of internal parking and manoeuvring areas, vehicles can generally manoeuvre more efficiently than the paths indicate. Notwithstanding this, the swept path plans illustrate that passenger vehicles can manoeuvre throughout and enter and exit the most difficult passenger vehicle parking spaces within the parking areas. It is however noted that the alignment of the access ramps and the basement parking aisles is such that oncoming vehicles cannot be accommodated in combination at the connections of the aisles and ramps. Give way signage is accordingly proposed to be installed within the basement manoeuvring aisles to appropriately assign priority in these areas. Further, convex mirrors are proposed to be installed at appropriate locations to ensure that oncoming vehicles are able to view one another as required. An internal traffic signal system could be provided to govern these oncoming movements. Council could reasonably impose the requirement for such signals to be installed, if considered necessary, through the imposition of a condition of development consent. It is further noted that the basement parking area forms a series of dead end aisles, without a formalised turnaround bay. The alignment of the internal basement parking aisles is such that vehicles are capable undertaking a three point turn in order to exit the site in a forward direction in the event of all parking spaces being occupied. The proposed basement parking area layout as it relates to passenger vehicle manoeuvrability is therefore considered to be satisfactory.
3.4.3 Bicycle Parking
A series of horizontal bicycle parking racks are proposed to be provided at basement level 2 within the common areas. These racks have been designed with the following minimum characteristics complying with AS2890.3:2015:
Bicycle parking rack spacing = 0.5m;
Horizontal bicycle rack length (depth) = 1.8m; and
Stanbury Traffic Planning Page
Oxford Street, Blacktown 17-046
14
Bicycle parking rack aisle width = 1.5m.
3.4.4 Site Servicing
It has previously been presented that site servicing associated with refuse collection and removalist vehicles is proposed to be accommodated within a single at‐grade on‐site servicing area located immediately to the north of the internal access roadway. This loading area has been designed to be capable of accommodating service vehicles with a length up to and including MRVs, providing the following minimum dimensions in accordance with AS2890.2:2004:
Loading bay width = 3.5m;
Loading bay length = 8.8m; and
Maximum grade within loading bay = 1:25.
Appendix 2 provides swept paths of MRVs accessing / departing the proposed on‐site servicing bay. The servicing bay is proposed to provide a minimum clearance of 4m, being compliant with that nominated as being typically required for refuse collection vehicle operation within DCP 2015. It is to be further acknowledged that such a clearance is also capable of accommodating Small Rigid Vehicles (SRVs) and a significant portion of MRVs associated with delivery and removalist requirements.

4. EXISTING TRAFFIC CONDITIONS
4.1 Surrounding Road Network
The following provides a description of the local road network surrounding the subject site:
Oxford Street, in the vicinity of the subject site, performs a local access function, providing a north‐south alignment between Gordon Street and Devitt Street.
Oxford Street provides an 8m wide pavement providing one through lane of traffic in each direction in conjunction with parallel parking along both kerb alignments, in the vicinity of the site. Traffic flow is governed by a speed limit of 50km/h.
Oxford Street intersects with a series of local east‐west access streets within the subject precinct in Clifton Street, Bruce Street, operating under major / minor priority control with Oxford Street forming the priority route.
Devitt Street, in the vicinity of the subject site, performs a local collector function, providing an east‐west alignment between Boyd Street and the Sunnyholt Road southbound carriageway to the west.
Devitt Street provides an 8m wide pavement providing one through lane of traffic in each direction with untimed parallel parking along the northern kerb and no parking along the southern kerb, in the vicinity of the site. Traffic flow is governed by a speed limit of 50km/h. A pedestrian refuge is provided east of Oxford Street.
Devitt Street intersects with a series of local north‐south access streets within the subject precinct in Oxford Street and Wallace Street, operating under major / minor priority control with Devitt Street forming the priority route.
Gordon Street in the vicinity of the subject site, performs a local access function, providing an east‐west alignment between Boyd Street and North Western Transitway.
Gordon Street provides a 10m wide pavement providing one through lane of traffic in each direction in conjunction with parallel parking along both kerb alignments, in the vicinity of the site. Traffic flow is governed by a speed limit of 50km/h.
Gordon Street intersects with a series of local north‐south access streets within the subject precinct in Peter Street and Sarsfield Street, operating under major / minor priority control with Gordon Street forming the priority route.

4.2 Existing Traffic Volumes Staff of Stanbury Traffic Planning have undertaken observations of traffic demands within the surrounding local road network in the vicinity of the site in order to accurately ascertain the traffic demands. Observations were undertaken between 7:00am – 9:00am and 4:00pm – 6:00pm on Thursday 27 April 2017. The following provides a summary of the peak hour traffic demands observed within the immediate vicinity of the site:
Directional traffic flows within Oxford Street adjacent to the site are less than 60 vehicles per hour; and
Directional traffic flows within Devitt Street to the south of the site are in the order of 100 – 150 vehicles per hour.
4.3 Existing Road Network Operation
Reference is made to the Roads & Maritime Services’ Guide to Traffic Generating Developments in order to undertake an assessment of the operational performance of the surrounding local road network. This publication indicates that a single lane of traffic accommodating peak hour traffic demands of between less than 200 vehicles provides a level of service ‘A’. Such a level service indicates free flow where drivers are virtually unaffected by other vehicles and have freedom to select their desired speed and to manoeuvre within the traffic stream. The local road network provides connectivity to the surrounding regional and state road network as follows:
Peter Street (accessed via Gordon Street) intersects with Sackville Street to the north under roundabout control;
Sackville Street intersects with Sunnyholt Road and Fifth Avenue under traffic signal control, providing exclusive turning phases facilitating precinct ingress and egress movements;
Sackville Street also extends to the east to connect with Lucas Road, which connects with Prospect Highway to the east, also operating under traffic signal control providing exclusive phases for turning movements; and
Devitt Street provides connectivity to and from the southbound Sunnyholt Road carriageway, with precinct egress movements being assisting by the operation of traffic signals at George Street which punctuate State Road traffic flow providing regular and extended gap.
Whilst traffic demands within the primary precinct access roads (Sunnyholt Road, Prospect Highway, Sackville Street and Lucas Road) are higher commensurate with their functional hierarchy in the road network, the abovementioned precinct access controls provide motorists with safe and efficient connectivity to the surrounding regional and state road network.

5. PROJECTED TRAFFIC CONDITIONS
5.1 Traffic Generation
Traffic generation rates for various land‐uses have been established through extensive surveys undertaken throughout NSW and published within their Guide to Traffic Generating Developments. The following sub‐sections provide a summary of the traffic generating potential of the existing and proposed site uses with respect to those rates established by the Roads & Maritime Services.
5.1.1 Existing Site Uses
Section 1.3.3 of this report presented that the subject site currently contains three detached residential dwellings accessed via Oxford Street. The Roads & Maritime Services’ Guide to Traffic Generating Developments provides an average traffic generation rate of 0.85 peak hour trips per dwelling for detached houses. The existing site uses are therefore considered to be capable of generating a total of three peak hour vehicle movements to and from the site.
5.1.2 Proposed Development
The Roads & Maritime Services’ Guide to Traffic Generating Developments specifies the following average peak hour traffic generation rates for high density residential development: 0.29 trips per dwelling Based on the above traffic generation rates, the subject development is expected to generate up to 12 peak hour vehicle trips.
5.2 Trip Distribution
The development has been projected to generate in the order of 12 vehicle movements to and from the subject site during peak hours, or nine additional vehicle movements over and above that currently generated by the existing three detached dwellings located within the subject site. These vehicle movements are primarily likely to comprise egress movements during the morning peak period and ingress movements during the evening peak period, associated with normal journey to and from work patterns of residential development. The development is projected, for the purposes of this assessment to generate 10 egress movements and two ingress movements during the morning peak hour. The development is conversely projected to generate 10 ingress movements and two egress movements during the evening peak hour.
Stanbury Traffic Planning Page
Oxford Street, Blacktown 17-046
21
For the purposes of this assessment, vehicle movements to and from the site are projected to be reasonably evenly distributed to the north‐west and east via Oxford Street, Devitt Street and Gordon Street respectively.
5.3 Traffic Impacts
The proposed development has been projected to generate up to 12 peak hour trips to and from the site. This equates to approximately one vehicle movement every five minutes during commuter peaks. Such a level of additional traffic is not projected to, in itself, result in any unreasonable impacts on the existing operational performance of the surrounding local road network. The previous assessment contained within this report has revealed that traffic demands within the surrounding local road network are reasonably low and accordingly motorists are provided with a good level of service with spare capacity. Whilst it is acknowledged that traffic demands within the surrounding arterial road network are considerable, the positive intersection control servicing connection to / from the surrounding regional and state road network allows motorist to access and egress the local precinct in a safe and efficient manner. In consideration of the above, the impact of the development is most likely to be a result of the safety and efficiency with which motorists are capable of entering and exiting the development. The low traffic demands within Oxford Street combined with the good sight distance provisions is such that it is envisaged that motorists will be capable of entering and exiting the site in a safe and efficient manner. It should further be acknowledged that the subject development results in a rationalisation of the site access arrangements, whereby the number of driveways servicing the site is to be reduced from three to one. This site access rationalisation will reduce the number of conflict points between the site and the abutting public road network and facilitate an increased on‐street parking supply.
5.4 Transport Impacts
The subject site is located within reasonably close walking distance to a number of bus services and a 10 minute walk to train services. It is accordingly expected that a proportion of the future residents within the subject development will utilise the surrounding public transport infrastructure to access destinations throughout the Sydney metropolitan area. The capacity of the existing public transport system is however not envisaged to be measurably affected by any additional demand associated with the development, given its limited scale.

6. CONCLUSION
This report assesses the potential traffic and parking implications associated with a residential development containing 40 dwellings at 13‐17 Oxford Street, Blacktown. Based on this assessment, the following conclusions are now made:
The proposed site access arrangements are projected to result in motorists being capable of entering and exiting the subject site in a safe and efficient manner;
The proposed off‐street vehicular parking provision complies with the relevant requirements of DCP 2015 for resident and visitor parking requirements;
The internal passenger vehicle circulation arrangements are capable of providing for safe and efficient internal manoeuvring;
The surrounding road network operates with a good level of service during peak periods;
The subject development has been projected to generate up to 12 peak hour vehicle trips to and from the subject site; and
It is considered that the adjoining road network is capable of accommodating the traffic projected to be generated by the subject development.
It is considered, based on the contents of this report and the conclusions contained herein, there are no traffic or parking related issues that should prevent approval of the subject application. This action is therefore recommended to Council.
