1. Why widen the road?
- To keep our community safe
Some members of our community have expressed concern with the capacity of Jandakot Road and expressed a desire for it to be upgraded
Current traffic volumes are approaching the limit for safe operating capacity
By 2031 about 26,000 to 29,000 vehicles per day will use Jandakot Road (in 2015 it was just under 14,000 vehicles)
By 2031, there will be an extra 22,694 people living nearby at Jandakot, Treeby, Piara Waters, Harrisdale and Haynes
The current road won't cope
There is not enough room in the current roadway (generally 20 metres wide on Jandakot Road) to fit 4 lanes (2 in each direction) plus turning lanes and a central median as well as footpaths either side.
Widening will be needed
2. How much land will be required to widen the road?
The current road reservation for Jandakot Road will not accommodate duplication across all of the new sections of the road. The original reservation was established more than 50 years ago when the area was mostly rural and undeveloped land.
While land has to be given up by Stockland for the duplication adjacent to its development, some additional land is required in other locations along the road. These additional land requirements, however, are based on having a design speed of 80kph. Reducing this to 70kph could provide the opportunity to adjust the road geometry, potentially altering the land requirements in some sections.
Similarly, changes to road geometry could provide the option for different drainage designs. The current concept design relies on the use of large retention basins. While such basins will still be required, it may be possible to put some of the drainage into other parts of the existing road reserve.
What we are doing:
Adjusted the road design and drainage layouts to see if modifications to the land requirements can be achieved.
Three options have been produced
A new acoustic (noise) model has been produced.
3. What will the speed limit be on an upgraded Jandakot Road?
Road speed is regulated by Main Roads Western Australia (MRWA), which sets design parameters for roads, including the sign ‘posted’ speeds.
To improve safety, the design speed of a road is normally required to be 10kph above its posted speed.
MRWA required Jandakot Road to be designed to 90kph, with a sign posted speed of 80kph.
However, the City negotiated with MRWA and had the concept design based on an 80kph design and sign posted speed, which gave us some flexibility with design.
With further development in eastern suburbs, the City would like to reduce Jandakot Road to a posted speed of 70kph, something MRWA is not supportive of. This was the preference of those that attended the workshop, acknowledging it would:
Make it safer for residents to turn across lanes of traffic
Reduce the noise generated by traffic
Provide an opportunity for changes to the road geometry to limit the impact of earthworks on adjoining properties
The features built into the design of a road have an impact on the approved speed.
The current concept design of Jandakot Road had three new roundabouts included in the eastern section (Fraser Road to Solomon Road). These will regulate access, such as into the Stockland (Calleya) estate; but they also have the impact of slowing traffic speed. Several landowners at the western end of the road asked if a roundabout could be included in this section (Berrigan Drive to Solomon Road). Placing a roundabout in this location would provide another north / south access point and it would assist the City’s argument to MRWA for a slower overall speed.
What we are doing:
Road design changes have been modelled, including changing the design speed to 70kph and including a roundabout in the western section of the road.
The City held a meeting with MRWA to seek approval for Jandakot Road to have both a design and posted speed of 70kph. MRWA was not supportive and still requires a design speed of 80kph.
4. Can we change the rezoning on our land?
The eastern part of the City is undergoing considerable change. This includes conversion of some land to urban and the intensification of industrial/commercial use in some other areas.
Expansion of activity at Jandakot Airport has been underway for several years. Several months ago, the City advertised Scheme Amendment 112, which seeks to alter and extend an existing additional use on the corner of Jandakot Road and Berrigan Drive (Urbanstone), to extend over the adjacent land which was previously a sand quarry. Such land is not capable of accommodating sensitive development, due to its proximity to Jandakot Airport. This Scheme amendment has been referred to the Minister for her consideration.
In 2015 the State Government advertised its new strategic plan for Perth, called Perth and Peel @3.5 million. This suite of documents provided a very specific land use plan for how Perth will grow to 2050. Such growth being based upon the vision and objectives that underpinned the document.
As part of this, the current Resource zoned land north of Jandakot Road is identified to be retained as part of the Rural Water Protection zone. The City has directly challenged this assumption, advising that the WAPC needs to consider whether the rural ribbon surrounding Jandakot Airport is a viable land use to protect the Jandakot groundwater mound. If the WAPC believe this to be so, it is imperative that appropriate levels of rural amenity be safeguarded through to 2050. This includes the relationship to ongoing development taking place on the airport.
The City also recommended, for the land south of Jandakot Road, that a more detailed strategic planning process occur to ensure that all options for highest and best land use were able to be properly considered.
What we are doing:
The City has sought confirmation from the WAPC on the status of all proposals and submissions submitted.
The dialogue with the WAPC will seek to establish the State’s position on the possibility of further changes to the area, particularly for the future of the Resource zoned land surrounding Jandakot Airport.
An update report was been prepared for the May Ordinary Council meeting on the land use matters.
5. What benefits can the road upgrade provide?
6. What are the State Government expectations for Jandakot Road?
Set out in Perth and Peel @ 3.5 million strategic documents transitioning from being just a local road to what is known as a Regional Road (e.g. North Lake Road and Beeliar Drive)
