Thank you. Looking at the satellite picture, the runways seem to be sufficiently separated for simultaneous departures and the article did not have a lot of detail. It seemed to be implied that the aircraft were at risk of colliding, but I was unable to see how that was likely. If both runways make left traffic (why?!), that certainly explains it.
It’s really odd. If they use the 09 runways and the 27 runways (depending on wind on any given day) then you have left traffic in the pattern on the north or south side. It could be some weird compromise with the neighbors about only having traffic on one side at a time. I really have no idea. But noise abatement in urban areas is a big deal so if it’s not geography the I’d guess it’s noise. I’m just a private pilot so maybe an ATP here can weigh in. I’ll ask around.
For a counter example look at Centennial in Colorado (KAPA) which had a similar setup and is my home field. They always have right traffic on one of the runways.
My guess is there is something in right traffic that they aren't allowed to fly over, or there is terrain/tall buildings potentially making it dangerous in inclement weather
