I think the first thing you need to do is to do a survey of the total area around the garage. It looks like your house is lower than the road assuming the road is at the end of the driveway in the one picture.

You may need to sit down, or lay down, in various spots around the garage to see the slopes. Of your lot is so level that you can not do it by eyeball, then you may need to do it with a long board and level, or one of those laser levels. Bottom line is you need to determine where the water drains to on your lot.

Only after you completely understand the topography of the lot, It may be necessary to cut a swale from you garage to the low spot from which your lot drains. Depending on the size, you may need some large equipment, or you may cut the sod off, shape the swale and then re install the sod.

There are french drains corrugated pipe and many other techniques, BUT you have to know where to construct them so the water goes where it naturally wants to go.

Thanks for your replies and suggestions. The road is actually about 80-90 yards+ from my garage. The sewage/septic is directly behind the house, which is why I think the ground there was topped off so much. Then I'm guessing after a couple years, the previous owners built the garage in just a terrible spot without thinking. There's a long ditch that runs from the road back a couple hundred yards, which is where everything is supposed to drain to. They built the garage directly between the topped off soil and the ditch.

I'll provide an aerial view for a better description. Even though it's about an eight year old picture by the looks of it.

The green square is the higher leveled ground. Blue arrows show which way the water normally flows. Am I going to have to go around the garage completely? Or change the landscape to make it all drain to the back?

You could make some french drains along the sidewalk next to the garage and redirect it out to the street, or make it drain back out to the direction where the other water usually flows (downward direction in your picture with the blue arrows). You could also drain it to the ditch if there are no regulations about what drains to that.

I think your only long term option, and probably the cheapest, to to regrade the yard and create a swale. I would create it on the right of garage (as seen in picture) and run it on the left side of the green square from about the patio? to about 5 feet beyond the back of the garage. It should end so the water drains between the back of the garage and the out-building

Assuming the lot drops of to the right from the green square, the swale does not need to be deep. About 8" lower and sloping from the garage. It should drain to the back of the garage, and move the water to the back, to the natural drainage.

I suspect you could cut it through the green square, but you would have your leach bed to consider (How deep are the lines)

The swale could be create with a sod cutting machine. Cut the sod from about a six foot wide section the length of the garage. Once the sod is remove dig the right three feed down about 4 to 6 inches and stack the dirt next to the garage. once you have all grades correct and flowing correctly replace the sod.

I think you could cut it across the drive way, but I think that opens a whole knew set of problems.

Also you could run a pipe from the house along the left side of the square, but the swale would be the less maintenance in the long term.

Wow! Picture is worth a thousand words. Yes, the garage should have been built a little differently. It is right in the big middle of the drainage direction toward the ditch. Had the garage been built on a slab about 4 inches higher than it is, that would have worked. Since it wasn't, then the drainage has to go around it.

It's easy to do this on paper and not have consequences, but just looking at it, my first thought would be to carve a swale beginning at about the middle of the house and curve it between in the middle back and between the back of the garage and the out building down toward the ditch. It needs to drop about 6 inches below the bottom of the garage and house at 10 feet away from the structures. That ensures you don't get flooding again - at least it ensures it to the bank and other lending institutions.
