At airports with more than one parallel runway it makes sense to keep power on one side and gliders on the other. So yes all glider traffic would stay on opposite side of power and land on adjacent runway. At Turf, there are three parallel runways going east- west so power stays on the north side and glider traffic on the south. The center runway is used by the power traffic mostly because the south runway is used for staging and takeoff. If it gets crouded, and it often did, both would use the center runway and plan on taking off to either side.
