ahh, the map is much help. for the next step, you could overlay a contour map over this and your property and see how the contours correspond with the water flows, both natural & man-made. (water moves perpendicular to contour in nature) my guess is that the swamp is the lowest elevation around. the drainage ditch may not necessarily create the problem (i/o/w swamp would be there even if road wasn't there), but it definitely exacerbates it.
is the neighbor whose land includes the swamp having issues with it? is there any structures sited in/around or is it otherwise causing a problem for them? if so, you might be able to talk them into a hugel-type remediation (similar to the swoosh-type above) to mitigate the drainage.
if not, then as RS noted, building a hugel that close to the road parallel to it risks creating a mushy road, especially considering you have multiple vehicles going up & down when the earth underneath it is moist. you'll get a stream going down the tire track closest to the drainage ditch. i know this, cuz i have one. another thing to consider is that if you do something experimental and it creates the aforementioned condition, you're going to have a bunch of angry neighbors calling you up and you're gonna spend even more time and fuel than you are now maintaining the road.
how about this alternative to consider: spend your efforts slow/spread/soaking the water before it leaves your property (the kite not the tail). start thinking in the area above where the map shows, especially if its at a higher elevation. divert as much of that runoff that you can before it gets to the driveway. is your orchard on the lower right of the kite in the drawing? what's residing in the lower left of the kite? which way is south?
you could alternatively plant some clover into that drainage ditch along your tail, cut and harvest it, and use it to mulch your plantings in the kite. clover is also good bee forage.
I think having land and not ruining it is the most beautiful art that anybody could ever want to own. - warhol
