Here's some frightening news for KC taxpayers in a new city report on economic development:

The Power & Light District is expected to generate a puny $4.8 million in tax revenues this fiscal year. That is far short of the $16.8 million in annual debt service needed to pay for its bonds.

Fortunately, the city previously has set aside an additional $8 million for the bond payments. That leaves a net shortfall of "only" $4 million that will come from the pockets of taxpayers this fiscal year.

That's bad news for neighborhood residents. Every extra tax dollar plowed into the Power & Light District is a dollar less available for providing services to residents.

But here's an even more financially frightening possibility.

When the next fiscal year starts in May, the Power & Light District will need to create $20 million in tax revenues to pay off the new projected annual debt service.

In other words, the district will have to generate four times as much tax revenues as it's creating this fiscal year.

So how much in tax receipts will the Power & Light District bring in?

It depends on a lot of things.

-- If more retail stores open to big crowds.

-- If the soon-to-open grocery store is a success.

-- If the movie theaters attract crowds..

-- If the already-open restaurants and bars can attract repeat business.

But what happens if the district falls short of that goal?

Once again, taxpayers would have to ride to the rescue.

For instance, if the district created $15 million in tax revenues, taxpayers would have to shell out an extra subsidy of around $5 million.

Or -- scary thought here -- the news could be much worse. If the district fails to lure much extra tax money at all, many more millions in taxpayers funds would have to be allocated for Power & Light debt payments.

That's not how former Mayor Kay Barnes and other supporters sold the project earlier this decade. Back then they predicted it would generate enough money to pay for its annual debt service.

So far, those expectations are not being met.
