I think I would undo the flowerbed mounds and save the driveway, if that's possible.
Good way to use the L2501 too.
It could be worse. You could find where the PO's cut three joists under the kitchen nearly through at both ends (to route A/C duct) just before you push a 300-pound refrigerator across them and find the fast way to get a refrigerator in the basement. Fortunately for me, I decided it would be better to move the water line for the ice maker first before moving the fridge. No wonder the kitchen always felt like we were walking on a trampoline. I raised the floor about 1/4 inch and nailed sisters to the joists. Still gotta fix the duct in the room below the kitchen.
That ain't tractor related, but it's certainly Previous Owner Screw Up material. The scary part is they called themselves professional remodelers. YIKES!

@forky said, I think I'd (re)move the flower bed to save the driveway. The alternative to reconfigure drainage may be much more expensive.
Hope you guys fared OK through the rain (other than the driveway). They were predicting 3-7 inches here, but we barely got a mist. I doubt it rained more than .25 inches. Also predicted 35-50 mph wind. We didn't get a stiff breeze. Just cooler temps, cloudy days, and a whole lotta hype. Could have been very different. I've got about a third of my yard stirred up at the moment from having 7 pretty large water oaks removed, on a slope, and ZERO grass growing on it. I'm glad we didn't get a torrent, though I would have liked enough to at least wet things down a bit. It's drier than a popcorn fart around here.
To all our friends in FL, GA, SC and NC, hope you guys aren't too long without power/services, not that you'll get to read this until you get power back. That was a big heifer, the only blessing being how quick it came apart. I hope recovery is already underway, and the scumbags don't start gouging and looting over there.
Our thoughts are with you.
