Use a laser level to establish a level plane. If you don't have that, you can use a mason string and a string level. The driveway should drop between 1/8-1/4" per foot for drainage. Measure from the garage to the street and multiply that length by, say 1/4". A 20 foot driveway should drop 5"(20 x 1/4) to the street.

4' level taped to a straight 2x4x10 & grade stakes - stakes are cheap & so's a 2n4 - if you don't already have a 4' level, its about time to buy 1

1/4"per foot will provide adequate drainage, more will not hurt. Most likely the height of both ends of the drive is already pretty much determined; one end will be at the street height, and the other at the height of your garage or carport floor. But even extra slope will not be effective if the form boards have sags in them, and the concrete is not worked properly, so as not to leave small low spots that will become puddles when it rains.

Are you going from garage/carport to an established street? Are you asking side slope if they are both the same elevation? We need more details.......

As you asked that question, you may want to read these helpful hints: http://www.nrmca.org/aboutconcrete/cips/06p.pdf

I want to see anybody with a vehicle with less ground clearance than an H1 hummer get into their garage. When I see stuff like that, it just makes no sense at all. How it could actually get that far is beyond me.

but I bet the kids with skateboards love it

If you can afforded the view you can afforded the rig to get you there.

I was trying to find out if those were real pics and where it was when I ran across a forum talking about driveways. One guy posted the same pic I have. One person wrote this:

Lol. I bet they had a low slump for that mud!

Years ago, saw a new house built with a group of 4 telephone cables (3") going completely through the middle upstairs of a house, minus a sheet of T1-11 panel siding on each end. Sided, roofed, doors and windows, exterior painted before Ma Bell moved them! Should have taken a picture for FHV, my boys wouldn't have needed college loans....

well, you know construction; hammer while the sun is shining because only God knows if the weather will be good enough to work tomorrow.

Did you ever think of renting it out as a ski jump in the wintertime?!

That is just about he most ridiculous thing I have ever seen. If this is up north, it would be worth a plane ticket just to see HO backing out of their garage on an icy morning. Guess it is a great help in enforcing the covenants about keeping boats or vehicles parked in the drive.

That's awesome. My mother's drive is pretty steep, but not quite that steep. However, it's twice as long and goes down to a parking area in front of the house.
