Downward slope at front of block - thoughts?

What are your thoughts on the below block? The block in question is at the far end and the left side is the street frontage. A builder has advised that we could build here with a steep driveway down to the home. This doesn’t seem appealing to me from a drainage perspective. Anyone know if there any other options with this? We’d probably not proceed with it if that’s the case.

 

where does the stormwater go? looks like there is another road in the background?

 

The only way I'd do it is with a split level house and the garage and some house being around road level then step down for the remainder of the house.

No way would I have a steep driveway down and nor do I do think you'd be allowed anything steeper than a 1 in 7 gradient.

 

It’s a corner block. I initially thought a split level would work but it’s a small block and the higher part is not enough area for a garage. I may give it a miss then
