Help with a drainage problem.
Ok, I'll try to keep this brief but detailed enough to get a good answer. I have a drainage problem in my backyard. see the attached pics to get an idea of the layout. Water from rain is pooling in the left corner for my garage and causing damage to the garage and lawn. I am trying to find the best way to go about fixing the situation whether its a french drain or regrading my lawn. Please ask me questions after looking at the pics because explaining it, i'm afraid I will forget to mention something. Thank you in advance. Drainage pics

Part of your challenge isn't so much grading as it is construction. The siding comes down to ground level. It would have been better if when the garage was built they put a row of blocks around the perimeter before they framed up the walls. That would have gotten your siding 6 - 7 inches off the ground.

Regrading would probably help, I suspect the sidewalk may have dropped down a little bit and no longer drains on to the driveway.

Any advice given here is general in nature and is not necessarily valid for your given area. If in doubt check with your local codes enforcement department for what is required when doing electrical, plumbing or structural work on your house. Permits may or may not be required in your area and home owners may not be able to DIY some tasks. I have no way of knowing if you have the skills needed to complete the tasks you are asking about, when in doubt seek professional assistance.

My advice may be worth exactly what you pay me for it. :-) For the record I did not stay in a Holiday Inn Express last night.

not the fix you want, but will help with keeping water out of the garage
build a "speed bump" in front of your garage door
this will not fix your grading problem,
but will keep water from actively running in the door
and a down spout leader would help on that gutter
run it out about 10' from the house

Here is one type of "speed bump" seals for your garage door.

Having a channel cut into the driveway and sidewalk and installing this would help move the water away from the building.

Unfortunately, the siding is just too close to the ground. A possible solution without jacking up the building would be to cut the lower 6" off and replace it with a "water table" a horizontal band of trim made from cellular PVC 1x6 with a cellular PVC drip cap on it. Azek is one brand of cellular PVC. Here is another with a picture of what a water table looks like.

Thank you all for the advice. I guess I wasn't as clear as I should have been, but what would be the best way to keep the water from pooling in that corner outside the garage? That's my biggest concern, as that water is rotting the bottom corner of the garage which is wood and not vinyl.

Also, where would you suggest the best place for a discharge for the water should I do a drainage trench?

The best place to run your drainage ditch is the shortest distance downhill that will accomplish your goals.

To stop the water from pooling at your building you need to have the concrete slope away from the building and have somewhere for the water to go. If the concrete is roughly level but the water is being held on the concrete by the grass, cut the grade down to give the water a place to go. If the slab has sunk down close to the building creating a low spot your options are: jack the concrete back up to create a slop away from the building, tear out the concrete and repour it with the correct slope, cut in a drain and pipe it away.
