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.
