They’re messing with an agency with a mission to improve downtown Amarillo’s fortunes.

Just the other day came word that interim Amarillo City Manager Terry Childers is considering moving some of Downtown Amarillo Inc.’s economic development duties to an office in City Hall.

My question then was: Why mess with success, given all the good that has happened downtown while DAI has been on task?

Now comes the latest boulder to get tossed into the machinery. DAI executive director Melissa Dailey has resigned.

I’ll admit that I’m not privy to Dailey’s reasoning, but the timing of her resignation — which the DAI board accepted unanimously — suggests some relationship to what the city manager is considering.

DAI board president John Lutz said that downtown’s future is “bigger than one person.” Fair enough.

Still, this isn’t good news for the city.

I’m not entirely clear about all the issues surrounding Dailey’s tenure at DAI. I’d heard some of the grumbling from those who blame Dailey directly for the Wallace Bajjali fiasco. Yes, Wallace Bajjali turned out to be all hat and no cattle with regard to downtown revival efforts here, but the breakup of the master development company didn’t bankrupt the city.

The two company principals had a huge falling out. One of them, David Wallace, has filed for personal bankruptcy. So they’re gone. Good riddance.

Has downtown’s movement slowed? No. Does DAI deserve to be castigated over the work that’s been done so far? Hardly. It has done well — and so has Dailey. The proof can be seen throughout the downtown district.

However, the non-profit agency now appears to be a target. My strong hunch is that Dailey didn’t want to become collateral damage if the city decides to revamp DAI’s mission.

The city is messing with success.
