Drainage for drive abutting brick wall

Our driveway has a widened section so there's parking beside an attached garage with brick exterior. Beside the garage there's currently what once was a flower bed about 30" deep running the wall between it and the drive. Now its just weeds I have to clear out 2-3x a year bc I don't havet he patience to keep it looking nice. I'm going to have the driveway widened so there's 2x parking there and passage to a future bigger garage, Thinking why not go ahead and tear out that section and pave (asphalt) against the drive and get a little more room and eliminate the weed maintanance.
The ground here is pretty flat.

Two concerns.
1 - am I looking at sealing problems having the asphalt against the brick? Do they usually slope it a bit there to encourage water to not pool against the wall?
2 - That wall has 2 downspouts from the gutter PO put in. There's a drain pipe buried under the ground against the house that collects water from the front, rear ties in, and it runs underground into the back yard (which has a slight downhill slope).
The problem is at the front the pipe is only a few inches below grade, and in the back maybe 7. Span between them is ~29'.
In talking with the driveway guy, he says they need to have enough depth for the stone bed, then the blacktop... so this pipe isn't deep enough. I can't just dig deeper bc then it wouldn't drain into the back yard.

In likely related news, the exit pipe in the back yard didn't work anyway, was always clogged and got covered by grass years ago... oops. So when it really pours, the pipe gets backed up and overflows onto the side drive anyway, but alot of it is absorbed by the dirt. I'm guessing more impervious surface will make that worse.

What options do I have?
1 - Give up on the pipe, have them slope the asphalt a little and hope for the best
2 - Run some kind of above-ground pipe along the wall (would that looks like shit?)
3 - Just leave the dirt bed etc and get some lower maintanance greenery
4 - ??
 
1 inch per 8 feet is minimum slope for proper drainage so I think you’re adequate, but there’s a that’s what she said joke in there I think I missed😉

You could run a surface drain

A diagram would be helpful. Is the driveway running water downhill away from the house or towards it?
Niether. The drive area in question is beside the garage, and is flat / level.
Why not pitch it all away from the house and just let the downspouts sheet flow on the driveway?
Isn't that my option #1?
I can't have the front downspout stick out laterally very much bc cars have to drive past it.
You could run a surface drain
oooh I like this idea.
 
Those come pre sloped with correct pitch when installed with the grate level from nds if you get the right model, the slope is in a plastic trough that has spots for rebar tie in and acts as a form that’s left in, or if you got a good concrete guy they can make a custom form and just buy the grate.

Concrete saw should remove a section of what’s there easy enough

 
Get that logical BS outta here!!! We're here to pointlessly discuss and argue, not actually make educated decisions and move forward!
So you are saying he should tear down the garage rebuild it 5x larger and raise the elevation 6" above the existing weedbed?
 
What I read, 'I'm too lazy to pull weeds, so I want to pave over this dirt area beside my house' :D
100% correct interpretation.
