Subject: Potential Development Traffic Impacts – Portuguese Club, 2 Strang Street Beaconsfield
Date: 19/12/17
Author: T Shaw
Attention: Dan Pearce
1 Background
The following considers the potential traffic impact associated with the development of the Portuguese Club site located at Lot 5 Strang Street in Beaconsfield. It is to be read in conjunction with the earlier Transport
Assessment titled ‘Transport Assessment. Beaconsfield Structure Plan – V3’ prepared by Shawmac for Landcorp
and dated August 2011. That Transport Assessment considered the potential development of land south of
Lefroy Road, Beaconsfield as shown on Figure 1 and was prepared in support of a Structure Plan. The 2011
report concluded that transportation impacts associated with the development of a residential subdivision of the
portion of land located to the south of Lefroy Road and to the west of the South Fremantle Senior High School
were acceptable and that the additional traffic could be accommodated on the existing road network. Analysis
showed that traffic would largely be distributed to Clontarf Road via Mather Road. With the exception of the main
north-south link, all streets within the subdivision were predicted to carry relatively low traffic volumes generally less than 1,000 vehicles per day, with most predicted to carry less than 500 vehicles per day.
It was concluded that the proposed street network both within the site and external to the site would provide an
acceptable range of choices for travel and that traffic volumes on individual streets would be below threshold
levels and that the amenity of the area would be preserved and safe movement options would exist for
pedestrians, cyclists and local traffic.
The intent of this Technical Note is to review the additional impact that the development of the Portuguese Club
site as residential units would have on the adjacent network when considered in conjunction with the possible
future development of the land immediately to the north.

Figure 1 - Site Location
2 Development Detail
A notional development comprising one hundred and twenty six (126) independent living units and eighty (80) aged care beds both with normally associated services and staff parking has been used to assess traffic impacts.
The assessment focusses on the traffic impacts associated with the residential component of the site and
provides comment on the likely impact of the aged care unit in general terms.
The proposed allocation of area is summarised below:
2 Bedroom Apartments: 62 units
3 Bedroom Apartments: 64 units
Existing club: 350 Square metres
Parking: 123 bays
3 | P a g e
Additional future use is indicated as including the following:
Aged care facility: 20 Beds per floor over 4 floors (80 beds)
Parking: 36 bays.
3 Traffic Generation and Distribution
3.1 Generation
The existing Portuguese club is being refurbished as a tenant lounge with the current occupants moving to other
premises.
The traffic generation associated with the 126 apartments is estimated in Table 1 and Table 2.

While not included in the proposed development of Lot 5 Strang Street, the addition of an 80 bed nursing home is
likely to increase traffic generation by 190 vehicle movements per day with 16 of these occurring in peak hour periods.
3.2 Distribution
Distribution has been determined by consideration of the most likely origin and destination desire lines between
the site and the surrounding areas and consideration of the constraints imposed by controlled versus uncontrolled
intersections and the effect this is likely to have on route selection. Impact on the road network immediately
surrounding the site is summarised on Table 3 and shown on Figure 2.

Traffic counts are not available for Strang Street, Culver Street or Naylor Street; however turning path surveys of
both the Naylor Street – Clontarf Road intersection and the Culver Street – Hampton Road intersection taken
over a representative midday period were used to predict the likely magnitude of daily flows in both streets. This suggested that Naylor Street would carry about 1,500 vpd and Culver Street, 1,000 vpd.
Additional flows attributable to the development on lot 5 Strang Street is envisaged to increase flows on Culver
Street by 430 vpd bringing the total daily flow to about 1,430 vpd and on Naylor Street by 225 vpd bringing the
total daily flow to about 1,725 vpd. The predicted flows are within the practical capacity of each road.
A recent SCATS count for the signalised intersection of Hampton Road and Clontarf Road indicates that volumes
The maximum increase in daily traffic on Clontarf Road is expected to be in the order of 200 vpd which can be
accommodated within the current geometry. The maximum increase in traffic on Hampton Road is expected to
be in the order of 300 vpd which similarly can be accommodated within the current geometry of the road.

3.3 Impact of the Land the Subject of the Approved Structure Plan (Landcorp Site)
The Landcorp site comprises that portion of land to the north and east of the subject site and was the subject of a
traffic assessment undertaken in 2011. The Transport Assessment considered two development densities, the
highest of which predicted an increase in traffic on Clontarf Road between Mather Road and Hampton Road of
approximately 380 vehicles a day. The Assessment also found that the development would not impact on any of
the other roads likely to be impacted by the proposed development on Lot 5 Strang Street. Current turning
volumes for the AM and PM peak hours at the intersection of Clontarf Road and Hampton Road were ascertained
form recent SCATS counts and are summarised in Figure 3. Predicted flows including the increases associated
with the Landcorp site and Lot 5 Strang Street are shown in Figure 4.

Sidra Intersection analysis of the existing and predicted turning volumes was undertaken using the current signal
phases and the resulting outputs are shown in Appendix A. This indicates that under the existing and predicted
flows the intersection will operate at an acceptable level of service with nominal queuing and short delays.
4 Conclusion
This assessment has been carried out to determine the traffic impact associated with the possible development of
Lot 5 Strang Street in Beaconsfield in context of the previously assessed Landcorp Site to the north and what, if
any, cumulative impacts are likely. The assessment concluded that:
• Traffic generated by the development of Lot 5 Strang Street is most likely to use Naylor Street to access Clontarf Road and Culver Street and Clontarf Road to access Hampton Road.
7 | P a g e
• All streets affected by the proposed development are capable of carrying the predicted increase in traffic without compromising the operational performance of those streets;
• In terms of cumulative impacts associated with the development of Lot 5 Strang Street and the Landcorp development site, only Clontarf Road will be affected by increased flows from both sites; and
• Assessment of the Clontarf Road – Hampton Road intersection confirms that under combined flow increases, the intersection will continue to operate at a high level of service.
As such, it is concluded that the inclusion of the Lot 5 Strang Street development in the Structure Plan previously prepared for the Landcorp site will not introduce nay major impacts and is acceptable.
