1. INTRODUCTION

This report has been prepared to accompany a development application to Blacktown City

Council for a residential development proposal located at 1086 Richmond Road, Marsden

Park (Figures 1 and 2).

The proposed development involves the demolition of the existing dwelling house and

associated outbuildings on the site to facilitate the construction of a new residential apartment

development (plus a small number of townhouses) comprising four lots, Lots 5, 9, 11 & 16.

Off-street car parking is to be provided for each lot in new respective basement car parking

areas in accordance with Council’s requirements.

The subject site is located within the “Marsden Park” precinct as outlined in the Blacktown

City Council (BCC) Growth Centre Precincts Development Control Plan 2010 document

which envisages creating a series of new walkable residential neighbourhoods supported by

local retail, employment, community, open space and recreational opportunities, in an

environmentally sustainable manner.

New local roads are to be constructed to serve these future dwellings which will ultimately

connect to the existing road network, in accordance with the BCC Growth Centre Precincts

DCP 2010, including Richmond Road.

The purpose of this report is to assess the traffic and parking implications of the development

proposal and to that end this report:

• describes the site and provides details of the development proposal

• reviews the road network in the vicinity of the site

• estimates the traffic generation potential of the development proposal

• assesses the traffic implications of the development proposal in terms of road network

capacity


2

• reviews the geometric design features of the proposed car parking facilities for

compliance with the relevant codes and standards

• assesses the adequacy and suitability of the quantum of off-street car parking and

loading provided on the site.

2. PROPOSED DEVELOPMENT

Site

The proposed development is located on the western side of Richmond Road, directly

opposite the Garfield Road West intersection. The subject site has a street frontage of

approximately 350m in length to Richmond Road and occupies a total area of approximately

10.8ha.

The subject site is currently occupied by a single dwelling house with ancillary outbuildings.

Vehicular access to the site is provided via a single driveway located directly off Richmond

Road.

The new local roads within the subject site and surrounding areas are yet to be fully

completed, as shown in the recent aerial image below.

Marsden Park Precinct

The site is located within the “Marsden Park” precinct as detailed in the BCC Growth Centre

Precincts DCP 2010 document which envisages the redevelopment of the area to provide for

a range of housing types to meet the needs of a diverse community, supported by local

services, infrastructure, facilities and employment, in an environmentally sustainable manner.

The “Marsden Park” precinct redevelopment makes provision for the construction of a new

local road network which connects to the existing arterial road network at several locations.

In addition, direct road connections to Riverstone and Schofields Railways Stations are

proposed to ensure regional public transport accessibility. Consideration is also being given

to extending the North West Rail Link into the precinct in the future. The provision of public

transport connections within the precinct will also promote a community that is less

dependent on private vehicle use.

Extracts from the BCC Growth Centre Precincts DCP 2010 document illustrating the

“Marsden Park” precinct Indicative Layout Plan, Residential Structure and Precinct Road

Hierarchy are reproduced in the following pages.

Proposed Development

The proposed development involves the demolition of the existing dwelling house and

associated outbuildings on the site to facilitate the construction of a new residential apartment

development (with small number of townhouses), comprising four lots, Lots 5, 9, 11 and 16.

A total of 266 dwellings are proposed in the new development as follows:

Lot 5 Lot 9 Lot 11 Lot 16 TOTAL

Studio apartments 2 1 3 4 10

1 bedroom apartments 3 7 5 0 15



3 bedroom townhouses 0 6 0 0 6

TOTAL DWELLINGS 76 95 55 40 266

Off-street parking is proposed for 440cars, comprising 383 residential spaces, 53 visitor

spaces and 4 dedicated car wash bays, in accordance with Council’s requirements as follows:


Residential spaces 111 133 80 59 383

Visitor spaces 15 19 11 8 53

Car wash bay 1 1 1 1 4

TOTAL SPACES 127 153 92 68 440

Each townhouse in Lot 9 will have its own single car garage within the Lot 9 basement car

parking area.

Vehicular access to each of the basement car parking areas is to be provided via respective

new two-way driveways located off the future internal roads.

In this regard, the proposed residential development includes the construction of a number of

new internal local roads with typical road reservation widths of between 17.4m and 20m, and

road carriageway widths of between 9m and 12m, which is consistent with the BCC Growth

Centre Precincts DCP 2014 requirements.

Loading/servicing for the proposed development is expected to be undertaken by a variety of

commercial vehicles up to and including 11m long rigid trucks, with loading bays to be

located on the ground floor level of each lot. Vehicular access to the respective loading bays

is to be provided via the abovementioned proposed site access driveways.

Plans of the proposed development have been prepared by The Bathla Group and are

reproduced in the following pages.

3. TRAFFIC ASSESSMENT

Road Hierarchy

The road hierarchy allocated to the road network in the vicinity of the site by the Roads and

Maritime Services is illustrated on Figure 3.

Richmond Road is classified by the RMS as a State Road and provides the key north-south

road link in the area, linking Blacktown to Bligh Park. It has recently been upgraded to dual

carriageway standard, with opposing traffic flows separated by a central landscaped median

island. Turning bays are provided at key locations.

Garfield Road West is also classified by the RMS as a State Road and provides the key east-

west road link in the area, linking Marsden Park to Riverstone. It typically carries one traffic

lane in each direction in the vicinity of the site however is scheduled to also be upgraded to

dual carriageway standard in the vicinity of the site, with construction works expected to be

completed in 2017.

Existing Traffic Controls

The existing traffic controls which apply to the road network in the vicinity of the site are

illustrated on Figure 4. Key features of those traffic controls are:

▪ an 80 km/h SPEED LIMIT which applies to Richmond Road

▪ a 60 km/h SPEED LIMIT which applies to Garfield Road West

▪ a 50 km/h SPEED LIMIT which applies to all other local roads in the area

▪ TRAFFIC SIGNALS in Richmond Road where it intersects with Elara Boulevard and

also Garfield Road West

▪ a CENTRAL MEDIAN ISLAND in Richmond Road which precludes right-turn

movements into and out of the site.

Projected Traffic Generation

An indication of the traffic generation potential of the development proposal is provided by

reference to the Roads and Maritime Services publication Guide to Traffic Generating

Developments, Section 3 - Landuse Traffic Generation (October 2002). The RMS Guidelines

are based on extensive surveys of a wide range of land uses and nominates the following

traffic generation rates which are applicable to the townhouse component of the development

proposal:

Medium Density Residential Flat Buildings

3 bedroom apartments: 0.5-0.65 peak hour vehicle trips/dwelling

The RMS Guidelines and the updated TDT 2013/04a are also based on extensive surveys of a

wide range of land uses and nominate the following traffic generation rates which are

applicable to the apartment component of the development proposal:

High Density Residential Flat Dwellings

AM: 0.19 peak hour vehicle trips per unit

PM: 0.15 peak hour vehicle trips per unit

The RMS Guidelines also make the following observation in respect of high density

residential flat buildings:

Definition

A high density residential flat building refers to a building containing 20 or more dwellings. This does

not include aged or disabled persons housing. High density residential flat buildings are usually more

than 5 levels, have basement level car parking and are located in close proximity to public transport

services. The building may contain a component of commercial use.

Factors

The above rates include visitors, staff, service/delivery and on-street movements such as taxis and pick-

up/set-down activities.

Application of the above traffic generation rates to the various residential components of the

development proposal yields a traffic generation potential of approximately 53 vehicle trips


31

per hour (vph) during the AM commuter peak period and 43 vph during the PM commuter

peak period, as set out below:

Projected Future Traffic Generation Potential

AM PM

Lot 5 (76 apartments): 14.4 vph 11.4 vph


Lot 9 (6 townhouses): 3.9 vph 3.9 vph



TOTAL TRAFFIC GENERATION POTENTIAL: 53.3 vph 43.0 vph

This is likely to comprise approximately 11 vph IN/42 vph OUT during the morning peak

period and 34 vph IN/9 vph OUT during the afternoon peak period.

Reference to the RMS Guidelines also indicates that approximately 25% of trips will be

internal to the precinct, involving local shopping, schools and local social visits. Thus the

volume of traffic accessing the external arterial road network is likely to be in the order of 8

vph IN/32 vph OUT during the morning peak period and 26 vph IN/7vph OUT during the

afternoon peak period.

In any event, that projected increase in traffic activity as a consequence of the development

proposal is minimal, consistent with the zoning objectives of the site, and will clearly not

have any unacceptable traffic implications in terms of road network capacity or traffic-related

environmental effects.

4. PARKING IMPLICATIONS

Existing Kerbside Parking Restrictions

Given the function and transit nature of Richmond Road, kerbside parking is expected to be

generally prohibited along both sides of the road, including along the site frontage. Kerbside

parking throughout the future internal local road network however is expected to be generally

unrestricted.

Off-Street Car Parking Provisions

The off-street parking requirements applicable to the development proposal are specified in

BCC Growth Centre Precincts Development Control Plan 2010, Section 4.3.4 document in

the following terms:

Multi dwelling housing and Residential Flat Buildings

Residents: 1 space per dwelling, plus 0.5 per 3 bedroom or more unit dwelling

Visitors: 1 space per 5 dwellings

Application of the above parking requirements to the 266 residential dwellings outlined in the

development proposal yields an off-street car parking requirement of 335 parking spaces as

set out below:

Lot 5 Residents (76 dwellings): 79.5 spaces

Lot 5 Visitors: 15.2 spaces







TOTAL: 335.2 spaces


33

The proposed development makes provision for a total of 440 off-street car parking spaces,

comprising 383 residential spaces, 53 visitor spaces and 4 designated car wash bays, thereby

satisfying Council’s DCP 2010 requirements as follows:


Residential spaces 111 133 80 59 383

Visitor spaces 15 19 11 8 53

Car wash bay 1 1 1 1 4

TOTAL SPACES 127 153 92 68 440

The geometric design layout of the proposed car parking facilities has been designed to

comply with the relevant requirements specified in the Standards Australia publication

Parking Facilities Part 1 - Off-Street Car Parking AS2890.1:2004 in respect of ramp

gradients, aisle widths and parking bay dimensions.

Loading/Servicing Provisions

Loading/servicing for the proposed development is expected to be undertaken by a variety of

commercial vehicles up to and including 11m long rigid trucks, with loading bays to be

located on the ground floor level of each lot. The manoeuvring area has been designed to

accommodate the swept turning path requirements of these 11m rigid trucks, allowing them

to enter and exit the site in a forward direction at all times.

The geometric design layout of the proposed loading facilities has been designed to comply

with the relevant requirements specified in the Standards Australia publication Parking

Facilities Part 2 – Off-Street Commercial Facilities AS2890.2:2002 in respect of ramp

gradients, overhead clearances and service area requirements for 11m long rigid trucks.

In summary, the proposed parking and loading facilities satisfy the relevant requirements

specified in both Council’s DCP 2010 as well as the Australian Standards and it is therefore

concluded that the proposed development will not have any unacceptable parking or loading

implications.
