Anyone know what a good driveway to garage entrance slope per foot is? My roof will be dumping off over the garage doors and I want to make sure no water is going to end up in the garage without getting carried away with a huge slope.

If concrete, I'd go between 1/4"-1/2" per ft, favoring the 1/4. For gravel, 3/4"-1" ft. It really doesn't take much to make water move. If you have concrete, during the winter, it doesn't take much (slope)to bust your butt!

A relative of mine put a linear drain In the concrete directly below where the water runs of his eves. To help keep water from making it in the garage. Thought I would throw that out at you for a idea.

Also make sure your concrete floor slopes down from where the overhead door seal contacts it. Helps prevent the seal freezing to the floor and blown rain runs away, not under the door. I assumed all flat work guys knew this, but it turned out they didn't and I wasn't there to catch it.

X2 on the slope. Also top of apron should be about 3/4" below top of garage floor. This will help keep wind from blowing rain in under the door, and if frost starts moving stuff around apron won't end up getting higher than floor height.

Put a gutter on it.
You don't want the rock dust splatter on the garage doors.
You don't want the splatter on the garage floor when working with the doors open.
You don't want the drip on a clean car going in or out.
Is the garage above the surrounding area?
Does the drive slope away or towards the garage?
Goodluck
