Harvey Field in Snohomish Wa. operates the largest jump facility in Puget Sound, they have a landing area east of the field, that most jumpers land at, but after (?) jumps and a sign off they can land back at Harvey. but all Harvey traffic is held west of the field because noise abatement does not allow aircraft over the city. So the jumpers use the east side and have no traffic problems.
I don't see why some thing like wouldn't work at Creswell
