Middle of the earth hidden map5/16/2023 ![]() Most cities have a “dial before you dig” hotline because there is no central holding place for data about underground space.Įnter Project Iceberg. Underground urban planning of an extension of a tube line, for instance, requires knowledge of where sewer and water systems, electricity and utility tunnels, bunkers, foundations, basements, cellars, vaults, passageways, archaeological remains, data centres, basements, and other transport tunnels are located. The Ordnance Survey has suggested that £5.5bn ($7bn) is spent every year on exploratory excavation just to figure out what’s underground, and according to a 2013 Mayor of London report, £150m of damage is done every year to underground utilities because of a lack of information. The new Melbourne tunnels will edge right up to this legal vertical limit. In Australia, although pre-1891 land titles went “to the centre of the Earth”, those issued after 1891 extend down just 15 metres (49 feet). In Mexico, for example, “property rights are effectively superficial, they do not extend volumetrically into the earth,” she says.Įven in places that have traditionally been ardent defenders of private property, however, once human beings took to the air and started tunnelling underground, the old heaven to hell ideal began to require caveats. ![]() Subterranean scholar Dr Marilu Melo of the University of Sydney explains that not all countries behave this way. Historically, the foundation of property law in the US and UK was enshrined in the Latin phrase “ Cuius est solum, eius est usque ad coelum et ad inferos” – which roughly translates as: “Whoever owns the soil, holds title up to the heavens and down to the depths of hell.” But Musk’s vision of underground dominance presents us with another thorny problem: what complications arise from passing the underground into the hands of private industry? And should the state be allowed to cede subterranean land to a billionaire to build a private transport system? From heaven to hell – with caveats Los Angeles does not have the same degree of vertical complication as a much older city like London, and the city council seems to be tentatively backing Musk’s new private transit tunnels. In London it will include transport tunnel information, geological records and maps of 1.5m km (0.9m miles) of underground utilities and four million kilometres of telecommunications lines. The space under London is now getting so busy that the Ordnance Survey, Future Cities Catapult and the British Geological Survey have joined forces to create a new initiative called Project Iceberg, which will attempt to aggregate cities’ subterranean data. According to Newcastle University’s Global Urban Research Unit, more than 4,600 basements have been granted planning permission in the last decade – in just seven of London’s 32 boroughs. In London, a city with 150 years of trenching, digging and boring to its name, the chaos is reaching new depths. Land prices tend to force private construction downwards, especially where there are planning limits on upward expansion Rollo Home, Ordnance Survey Homeowners received a letter explaining that their “sub-stratum” land was being sequestered – without compensation. Outside Melbourne, Australia, for example, the government is currently preparing to bore underneath 260 properties – including more than 100 homes – to build a road tunnel. Indeed, in most major cities, just as you can’t expect commercial planes to stop flying over your house through aerial highways, you also can’t prevent public transport routes being dug out underneath it. ![]() ![]() Photograph: James Baily/Barnes Private Office It does not store any personal data.A basement development in London.
