Screen shot of the video summary showing one view of the area in Tempe that would be affected by the motorway.  The violet line shows the route of the motorway

Called ‘WestConnex’ & starting at Parramatta, the M4 will be widened probably removing many of the trees planted for the 2000 Olympics. It then travels up a widened Parramatta Road with an under street level slot for the motorway with Parramatta Road still able to function. A small inset in the video link below shows a boulevard-look with lots of street trees beside high-rise residential development.  This will be a huge change for the suburbs along Parramatta Road.

The WestConnex Motorway travels up to Taverners Hill in Petersham & then underground with a 5km tunnel from Taverners Hill to St Peters, “returning local roads to the Inner West community.”  No stacks were mentioned, but they come with tunnels as far as I am aware.  The tunnel runs under the Princes Highway side of Sydney Park coming to the surface in the grounds of what I think is ‘Dial a Dump’ where coal seam gas mining was to happen & may still happen yet.

The motorway then travels beside the Alexandra Canal & through the container terminal at Tempe.  It then travels above/beside the Tempe Wetlands & within spitting distance of the houses below at East Tempe. From there the road travels through all the trees planted beside Tempe Reserve & along the eastern side of Tempe Reserve through the playground & picnic facilities & over the Cooks River to travel through the Kogarah Golf Course, finally meeting with the M5 that will also be widened.  The point at Tempe Reserve is the only point along the Cooks River until the river enters Botany Bay.

There appears to be an alternate route shown very briefly at 2.31secs on the video. This follows the Alexandra Canal avoiding the Tempe Wetlands, though it still travels through Tempe Reserve.

The video says that the project is the ‘highest priority’ for the NSW government with the route of the WestConnex still at concept stage.  The TV news tonight says it will probably be funded by multiple tolls.

Way back in 2007 there was a US study published in the Medical Journal The Lancet, “linking motorway pollution with permanent and life-limiting damage to children’s lungs. People who live within 500 metres of a motorway grow up with significantly reduced lung capacity, & even children who have never experienced asthma are at risk.”  - http://bit.ly/exrUEp  

I wrote about a 2010 study done by the US Health Effects Institute who reviewed 700 worldwide health-pollution studies. They found that traffic pollution within a 500-metre radius of a major thoroughfare was likely to exacerbate asthma in children, trigger new asthma cases across all ages, impair lung function in adults & could cause cardiovascular illness & death.  See – http://bit.ly/QpiYx6 

Last July 2012, the NSW Department of Health said that an 80% increase in lung cancer cases in residents living near the Turrella stack was unlikely to have been caused by air pollution from the tunnel stack because it takes longer for lung cancer to develop.  NSW Health said they could not find a reason for the massive cancer spike in Turrella residents saying, “it could be purely chance because rates do go up & down & it’s a smallish area & the (cancer) rates are quite volatile in smallish areas.”  Short video here - http://bit.ly/OgXqfP

However, a 2009 article said that researchers from Macquarie University & Queensland University of Technology found that regular users of Sydney’s M5 East tunnel were risking chronic health problems because of high levels of air pollution in the tunnel, which were 1,000 times higher than in the city. -  http://bit.ly/UaDbtc

So, if it is risky to your health to repeatedly drive in the tunnel, why isn’t the air pollution that comes out of the tunnel in a concentrated form risking the health of nearby residents?

Scientific research studies like the above make me wonder why governments continue to focus on building roads rather than putting the substantial money needed to build these into better public transport.  Many people think more Motorways are not the answer as they fill up & need to be bigger within a very short length of time.

Dreadful is what the Motorway will do to the wetlands, to the park above the wetlands, the considerable tree loss in Tempe & the ruination of Tempe Reserve & the Kogarah Golf Course & to the residents of Tempe & Marrickville.  Perhaps St Peters & Petersham residents will be affected too.  This Motorway may have a bigger impact than I can think of at this stage.

Marrickville LGA has the smallest amount of public green space in Australia, so if this Motorway goes ahead as planned, we will be losing more public green space in Tempe Reserve. This area of Tempe Reserve in particular is usually jam packed with people who use the great children’s playground, the barbeques & the picnic kiosks as well as the river for fishing.  Large groups of children use the basketball courts behind the Robyn Webster Sport Centre as well.  Tempe Reserve & the wetlands are a vital area for wildlife habitat in Marrickville LGA.  It is not the place for a major motorway if you care about the health & happiness of people & the environment.

Drivers will be ecstatic, so I expect that there will be anger at any community opposition to the Motorway.  However, I am pretty sure there will be significant community opposition in this municipality if the past is a realistic guide.

Street trees along the City of Sydney Council end of King Street Newtown proving it can be done

We know that the particulate matter in air pollution comes from vehicles & coal power stations causes respiratory disease, including asthma in both children & adults as well as heart attack related death. Now 2 new research studies done by entirely different research groups in Germany & the USA have shown that particulate matter also increases the incidence of Type 2 Diabetes.

… the new data provide important & more rigorous evidence that real-world pollution may be tampering with blood sugar control in a large & growing number of people.

The researchers used proximity to roads — where vehicles would be a major pollution source — as a proxy for exposure to fine particulates. Women who developed diabetes were more likely to have lived nearest to heavily trafficked roads.

Compared to the 25% of women living farthest from busy roads, the relative risk of developing diabetes was 15% higher for the 25% of women living closest to major roadways.

There is a growing body of literature suggesting that people with diabetes may be more susceptible to the harmful effects of air pollution.

All the more reason why we need to start planting more street trees, especially on & around main roads. This issue is fast becoming one that will have serious impacts on our health system.  It makes sense to use nature to try to lessen the impact of our 21st Century lifestyle as money spent now may help mitigate the financial cost of disease in the future.

An article was published in Reuters Health this week about research done by Dr Robert A Silverman of the Long Island Jewish Medical Center in New York.  Dr Silverman studied the link between particulate matter (pollution from vehicles & coal-fire power plants) & 8,000 heart attacks in New York City between 2002 & 2006.

“As the levels of particulate matter air pollution increased, more cardiac arrests occurred.”

“When they looked at fine particulate matter (particles 2.5 micrometer or less in size), they found that the risk of having a deadly cardiac arrest rose by between 4 & 10% with every 10-microgram-per-cubic-meter increase in fine particulates.” The current EPA standard of 35 micrograms per cubic meter is grossly inadequate.

“Being indoors may offer only limited protection since small particles can penetrate into buildings and homes.”

As far as I can ascertain, there are only 3 things that stop particulate matter –

  • removing all vehicles from the roads,
  • closing down coal-fire power stations &
  • trees.

In 2003 there were 204 million vehicles on the road in the US.  This increased to 246 million vehicles on the road by January 2010.  In 2009, there were 50 million more vehicles on US roads than 6 years previously, though in 2010, it dropped to only 46 million more. In comparison, China is estimated to have in excess of 70 million vehicles on the road by the end of 2010 & expected to have over 200 million by 2020. Still they wont have caught up with the Jones’s.

Australian statistics were hard to get though I did find that 13.2 million vehicles, including motorcycles, were registered in Australia at 31 March 2003.  I would expect the numbers to be much higher for 2010.

Worldwide it is predicted there will be 1.2 billion vehicles on the road by 2015.

Only the cost of petrol or a severe shortage of oil is going to bring down vehicle use numbers.  You can see why most cities are trying to encourage public transport use, walking & cycling.

As for coal-fired power stations, Australia does not look like it is planning to reduce or stop them with up to 12 new coal-fired power stations planned across the country.  Unfortunately, in NSW they intend to mine for coal in the small bits of land that is Koala habitat.  If you are interested in this – https://www.savethekoala.com/ is a terrific resource & Deborah’s (Tabart) Diary gives regular updates about the Koala situation in Australia https://www.savethekoala.com/deborahtabartsdesk.html

Everyone loves this end of Crystal Street because of the large trees

Lastly, we come to trees. Trees remove up to 60% of street level particulate matter & dramatically improve air quality, which is why their presence is so important in high traffic areas.  The more trees in an area, the better the air quality. Trees also absorb other pollutants such as Ozone, Nitrogen Dioxide & Sulfur Dioxide through their leaves.

A street tree removes 9 times the amount of air-born pollution from passing traffic than does a tree on a nearby property.  Street trees also improve the air that enters people’s homes, especially important as particulate matter penetrates buildings even when the windows are closed.

Large trees provide the most benefit as they provide greater absorption of particulate matter.  Small stature trees that are the perhaps the most common sized tree across Marrickville LGA have far less ability to do this.

The issue of pollution from vehicles is becoming an issue that is too hard to ignore. I am of the opinion that many of our roads in Marrickville LGA are quite dangerous in this regard due to the large volumes of traffic every day. Even small suburban streets that are more like lanes can have in excess of 7,000 vehicles/day.

If the Marrickville Metro expansion goes ahead there will be a potential loss of 142 trees & an extra 4 million shoppers a year. You can just imagine the air pollution around the surrounding residential streets & the planned plaza.

Parramatta Road & the Princes Highway are mostly treeless in the section that is under the governance of Marrickville Council.  It’s not just a matter of beautifying areas that are seriously lacking in aesthetic beauty, it is a matter of public health.

Parramatta Road under the governance of City of Sydney Council

This problem is not going to go away.   I think the NSW state government should allocate money to Marrickville Council to plant trees on these main roads. This is a major project requiring funds that Marrickville Council cannot afford. For this reason it is imperative that the state government fund it as a special environmental project.   It will save the government much greater amounts of money in the long run as people living in Marrickville LGA may just end up in the health-care system.

The population of Marrickville LGA is going to expand. We will all be living & shopping closer together & despite what the authorities say, I believe that the ‘culture of the car’ is not over by a long-shot.  If I am correct, then the issue of pollution-related illness from vehicles is going to spike in the Inner West & we are going to need many more trees to try & lessen the particulate matter that the residents & workers are breathing in.

On 29th June 2010 I posted ‘Living close to a main road is bad for your heath’ which discusses this issue further.
