I've been quietly reading along these past couple of days -- thank you to everyone who posts or answers questions. There are questions I didn't even know I had! 
That does sound flat -- thank you! As for running up my hill without collapsing, I'd settle for being able to walk up it without stopping for a couple of breaks. Not only is it steep, it's LONG!

What a dream house! You plan on using this hill in your training, right? The answer is YES, I hope. You really need to spend a day each week running up the hill. It will balance out the leg muscle keeping your legs halthy. Simply walk or jog to the bottom then run up at an effort that leaves you unable to say more than a word or two per breath.
Oh, to answer your question… Disney is flat, and I live on a coastal plain where a hill is a a driveway approach. The Disney hills are freeway overpasses where the slope is less than 2% or if your car had cruise control, the foot feet would barely move at all.
