Smooth Polyline without Crossing Polygon Container

I have hydrographic flowlines which I would like smoothed. For each flowline there is a polygon surrounding it (the river's floodplain). Even if I reduce the tolerance down to a small number in some areas the flowline is crossing the floodplain boundary, which cannot happen in our model. I would like to retain a smoothing of between 500-1000m.

Is there a method that can tell the smoothed lines not to cross a certain polygon boundary? Would incorporating the underlying NED help in any way. I have been racking my brain for 2 weeks on this issue and have yet to find a resolution.

I attached a Word doc to show you the issue.

Thanks you, James
