This could be an old wive's tale

I don't think XNA is big enough to warrant parallel runways. I think the previous post about needing a new runway was more accurate. It may have something to do with a minimum distance needed between the runway and the parallel taxiway. I know a few airports that had to move the runway further from the taxiway.
