Denmark Parliament Approves Giant Artificial Island Off Copenhagen 58
Plans for an artificial island to house 35,000 people and protect the port of Copenhagen from rising sea levels have been approved by Danish MPs. The BBC reports: The giant island, named Lynetteholm, would be connected to the mainland via a ring road, tunnels and a metro line. The approval by Denmark's parliament paves the way for the 1 sq mile (2.6 sq km) project to begin later this year. But it faces opposition from environmentalists who have concerns over the impact of its construction.
Plans for Lynetteholm include a dam system around its perimeter, with the aim of protecting the harbour from rising sea levels and storm surges. If construction goes ahead as planned, the majority of the foundations for the island off Denmark's capital should be in place by 2035, with an aim to fully complete the project by 2070. Some of the environmental concerns include the transportation of materials by road, which will involve large numbers of vehicles to move the 80 million tons of soil required to create the peninsula alone. "There are also concerns among environmentalists about the movement of sediment at sea and the possible impact on ecosystems and water quality," the report adds.

The name is taken from the 19th century sea fortress adjacent to the planned island. That name is in turn derived from french "lunette" - meaning "half moon" - presumably because of the defensive shape of the fortress.

And "holm" in Danish is a suffix roughly denoting "small or low lying island." Other examples from the Copenhagen area are Gammelholm, Slotsholm, Holmen, etc. The other common Danish word for island is "ø" (e.g. Refshaleøen). Note that the "en" in some of those names is how Danish handles direct articles. "The island" is "øen" as opposed to "an island" which is "en ø."
So the developers could have chosen "Lynetteøen" if they had really wanted to. But it sounds stupid and probabl

2.6 sq.km is 2600 ha, projected to take about 35 year, some 74 ha/yr. And that is after building "foundations" for 15 years.
Obviously they're using different techniques, which TFS doesn't detail.
There are things that don't scale terribly well - getting the made land to stop moving and de-watering for one. I guess they've realised that they can't speed these things up. Or they've got a non-engineering constraint, maybe in the financials. Already

Civil engineering is more complicated than that. You need to know what the seabed is made of before you can consider if it is capable to be pumped around. And when you dig into the details you'll see that no, the Dutch don't just pump it off the seabed. In fact there are a few large lakes in the Netherlands that exist precisely because the sand on the seabed wasn't suitable for the specific construction. E.g. Massvlakte construction resulted in the creation of the Oostvoorne Meer since the seabed was too so

It will be high-rise high-density housing.
1 square mile / 35,000 people works out to 800 square feet (or about 80 square meters) per person. Raw. A significant chunk of that will be "shared" space (roads, shops, schools, probably no airport, but probably a helipad or three, and so on...), which means it will probably be closer to 400 square feet at ground level per person. To get "acceptable" footprints, they're going to have to go up.

Not yours, but those in the article.
This "news" is making news every where. The "artwork" of that island can probably house 3000 people. In an environment that looks so artificial that probably no one wants to move there.
What kind of jobs can you do there?
a) maintaining the island
b) remote computer work
c) nurse (you need a nurse or two with so "few(many?)" people
d) a doctor
e) a post delivery man
f) one or two grocery stores - perhaps a bakery
g) kindergarden
And that probably sums it up.

This is basically a flood control project. (Score:4)
They're creating a new neighborhood in a very expensive city to offset the enormous cost of building the kind of tide control gates Venice has.
That's why 2070 is their "complete by date". Conservative projections show a sea level rise on the order of 0.3 - 1.2 m by then. Sea levels have risen 100 mm since 1990, which is less than 4 inches. That's not enough to *flood* cities, but coastal cities have effectively been built right up to the edge of what was *historically* safe from flooding. They've been experiencing a lot of expensive nibbling at the edges during high water events, and that trend will only accelerate even if the level of rise remains at the lower end of the likely range.
Boston is about the same size as Copenhagen, and is weighing a flood control system. Boston harbor is protected by a pair of peninsulas jutting into the Gulf of Maine with scattered islands and shoals between them. The proposal is to build a chain of tide gates from island to island spanning the gap that would be raised during flood events. The cost of the project is estimated at twelve billion, and some are arguing that abandoning vulnerable parts of the city might be more economical.
It's conceivable that Copenhagen, by creating new and highly valuable land, could actually make money on the project. Financially it's a great idea. Environmentally it's painful, because it involves destroying and radically altering marine ecosystems.

If the rate of ocean rise continues to change at this pace, sea level will rise 26 inches (65 centimeters) by 2100 -- enough to cause significant problems for coastal cities, according to the new assessment by Nerem and colleagues from NASA's Goddard Space Flight Center in Greenbelt, Maryland.

This is the old cherry-picking the baseline fallacy. Since the rate of sea level rise since 1990 has risen sharply, setting your baseline all the way back 1820 will swamp the dramatic increase of the last two decades with 150 years or so in which sea levels were rising more slowly.
The resulting figure is not necessarily *wrong*. It's just an irrelevant figure when it comes to predicting the future.

Most of Denmark is still rebounding from the last ice age partially offsetting sea level rise. Copenhagen will rise around 12 cm in the next 80 years. But even then it is expected that the sea level will rise around 50 cm in the coming 80 years. But the problem is really that storm surges become worse. And Lynetteholm is actually designed to protect inner Copenhagen against storm surges in the future (it is not a problem now). See the map here:

See, here's the rub: you can spend a fortune on roads to move material (or materiel, cf. the US Interstate system). You can pay up in repairs for moving very heavy vehicles over them, or you can split it into lighter loads to lessen your repair bill. If you do that, you pay in increased vehicle and fuel costs.
Why not link a bunch of dumb cars together to distribute the load, with an engine(s) pulling/pushing them, and maybe put it on rails because durability.
