Ground zero money sump

If nothing else, Tuesday’s Port Authority audit focused a fresh spotlight on the enormous construction costs attending preparation work for some of the elaborate projects intended for the World Trade Center site.

Most of those projects are defensible (even if their price tags are not).

A conspicuous exception is the planned performing arts center — an unaffordable, redundant impediment to timely completion of the overall project.

And when you fully digest the numbers — and consider how wholly unnecessary the center is — you come to one inevitable conclusion: It needs to be scrapped, pronto.

Start with the PA report: It cited some $200 million in costs for work being done to facilitate construction of the center.

Two things:

* That money would be better spent on pressing PA needs — fixing crumbling bridges and tunnels, for instance.

* History suggests the center will never pay its own way — becoming, rather, a black hole for city and other public funds.

The PA hopes to be repaid for that work . . . one day, presumably by the arts center — though who knows if it will even be built, let alone fork over any funds.

Indeed, as the report suggests, recouping money for such work, even from other public agencies, like the MTA or City Hall itself, is never a sure thing. The PA is already eyeball-deep in a number of World Trade Center-related funding disputes with those very players, as well as others.

“In the face of uncertainty of collections, the Port Authority should enforce strict controls and curtail development of non-essential third-party requests,” said the auditors.

Requests, that is, like the platform and other infrastructure for . . . the Performing Arts Center.

Keep in mind, this is a project that — more than 10 years after 9/11 — still exists mainly in the minds of its proponents. It was only six weeks ago that a board for the center was formed — and its backers have yet to create a nonprofit entity to run it.

What will the center consist of?

That’s anyone’s guess; there’s no final design in place. Which is also why no one knows its final price tag — which likely means even more upward pressure on tolls, given that the cost for the nearby National Sept. 11 Memorial & Museum is now pushing a breath-taking $1 billion.

The Lower Manhattan Development Corp. has set aside some $100 million for the arts center, with countless millions more (supposedly) to come from private donors.

Good luck with that.

There’s more: Everyone knows that rebuilding the site has taken more than a decade, in part because of its massive Rube Goldberg-like complexity; the arts center only makes things worse.

As Post columnist Steve Cuozzo has detailed, there is no end to the Ground Zero construction complications — and delays — caused by the arts center.

More to the point, does the city even need another performing-arts center? It’s already got some 45 city-funded cultural centers — like Lincoln Center, the Apollo Theater and the Brooklyn Academy of Music; countless others pay their own way.

So it’s not like shelving the center would cause cultural deprivation.

No, the Ground Zero Performing Arts Center is yet another boondoggle, with unknown, ever-escalating costs.

Now’s the time to deep-six it.

Before it’s too late.
