I’ve had enough of these crazy backyard-renovation-blitz shows. Never do they pay attention to streetscape, neighbourhood, place making or community. They don’t create any legacy. So I’m running my own series right here – the Front Yard Blitz series.
The goal is to see how we might refurbish our suburban streets to become more resilient, more engaging, environmentally restorative and maybe even healthy for us.
This first instalment looks at the dog’s breakfast of overhead power cables lining most existing neighbourhood streets.
In 1838 Samuel Morse kicked off the telegraph revolution and still today we’re adding more junk to the very same infrastructure that was built for the telegraph. The reason we’re not witnessing a nation-wide project to put it all underground is mostly due to up-front cost.
For reasons that will become clear, getting the cables underground is perhaps the key enabler for this green street project. Besides the reduction in storm damage, reduced road deaths and bushfires, if we can get the cables underground it lets us proceed with a whole range of value-adds which we’ll explore as we go.
So the question is, ‘how much?’.
I’ve found a range of figures online for Australia, and the average cost per-household seems to be around $12,000. Of course this is based on a range of assumptions and conditions, and for the sake of argument let’s say $15,000 per household for a typical suburban neighbourhood with detached or semi-detached homes.
This might go up or down depending on what other works are being undertaken at the time, e.g. footpath or road resurfacing. Some utilities require you to pay the entire bill (e.g. Ausgrid) whilst others (e.g. Western Power in south-west Western Australia) might pay 25%. Local Councils will also usually chip in, sometimes up to 50%, and some State Governments also contribute up to 25%. Naturally I’m too time-pressed to research all of this across all of Australia, but the punchline seems to be that you’d be unlucky to have to pay the entire cost yourself.
In Perth the cost for the resident is down to around $4,500 thanks to the multi-agency contributions. I haven’t been able to determine whether or not this includes the cables from the street to the homes, so there may be some additional cost.
So would you pay $15,000 (assuming no funding support) just to get the cables underground? And what chance do you have of getting the majority of residents in your street to do the same (which is required before the project can proceed)?
An Australian National University study concluded that putting the powerlines underground can increase a home’s value by 3%, which is for example a $15,000 rise on a $500,000 property. ‘Money for jam’ as they say. Street presentation is one of the first selling points in real estate, so a street without all that junk in the air always stands a better chance.
In the next posts we’ll start to explore what is possible if we can remove the encumbrance of the overhead cables.
