As shown is perfectly acceptable.Watch out for the extra movement of contours, because you may in inadvertently alter portions that will break some of the rules of the problem.
Back to Sparky83's comment. I think you should have one or two contours altered to create a berm up hill from the display in order to preemptively redirect surface run-off into the the new swales. That would be excessive. Gravity does not need any help.
