Or is it better to just jack garage up and add new course and floor on top of existing? Did not get a warm fuzzy watching a couple videos online about raising floor.

How is the garage foundation done? Does it have a footer, perimeter wall, and then a floating slab inside? Or does the curb/stem wall sit on top of the floor slab which doubles as a footer?

Pad and footing are all one. 2 course of cinderblock on top. In 2010 we had water above the cinderblock by a few inches.

My guess and I need to get an engineer out here to prove it is that when the new development went in and they raised the property over there, the berm acts as a dam so to speak and hold the water where before when it was a farm it probably just all spread out so was never a problem.

Heavy rains started last night and supposed to end later today. As of this morning here is what it looks like. Still dry inside garage though.

Rent a rotary laser and do a detailed grade survey of your lot.

If the back part is shaped like a lens that will limit your options.

Could you run an underground tile from the back to the front? Will the grade allow it?

During the 2010 event was the street underwater too?
If so then the only permanent option is to make the shop floor higher.

Yes had water from the back out to the street. Had to build a plank walkway from curb across driveway to front porch steps.

The flooding in the street was a result of the collapsed drains which were fixed that year. No street flooding since then.

Township engineer is supposed to swing by today to take a look.

Hire a local civil engineer to examine the condition of your property and those around it...it is what we happen to do for a living...

Dry well wont do anything. Thats way to much water and the ground looks prety well saturated when its under 1ft of water. Drywells have there place but there are very few situations where they work well.

I have a dry well in heavy clay soil. It works. The "pit" is 8' round. That guy is standing on 3' of 3/4" crushed limestone and is still about 2' below grade.

I now have a dry garage floor. Admittedly, my problem was not as bad as the OP, but it would take 3-4 days after a heavy summer storm for the yard to dry out enough to mow.

It does overflow about once or twice a year, but I run a pump for a couple of hours and get it down to just below grade and then nature takes care of the rest.

Until you get a permanent fix, you might want to invest in some sandbags for the door of your garage. When not in use, put them on a pallet behind the garage under a tarp so the Sun doesn't destroy the bag.
