Well had a 2 hours meeting with the builder yesterday, laid out the concrete, complained about a laundry list of items and went over what paint colors go where in the house with the painters.
Looks like the cabinet guy screwed up again (this is like the 6th thing he has had to remake due to errors on his part). So the pantry doors will be taller, he didnt take the box all the way up to the rough opening, there is a 4" gap on top, which would now make the opening 79" tall. Close enough for me.
Biggest issue I was concerned about was confirmed by the concrete guy, I had brought it up the the builder before they even dug the footings on the shop yet he said it was perfectly fine. Excavator missed on depth both the shop and the house. House is 6" too deep or at least the egress window is and the shop is 12" too high. Concrete guy said he would have preferred that the house be 6" above the floor of the shop so that grading could be done correctly. The entire 50 foot wide shop front also slopes towards the house as that is how the lot slopes naturally, and its a another foot or two slope over the 50 foot.
No on to what can we do about it. We have 15 feet between the edge of the concrete to the edge of the foundation. I have read its best to have a 6" drop over the first 10 feet out from the foundation. Which now leaves a 12" drop over 5' from the concrete drive.
Options that I can think of:
Shallow french drain and running it across the back yard to the hill on the east side, would be around 75-85 foot of piping.
Creating a flower bed that is say 40-48" wide with a 18-20" retaining wall to hold up the dirt to the drive way. this would allow the grade to be sloped down into the retaining wall, but not sure how this would hold the water coming off the driveway, or if there would still be a washout issue.
Form up some 2-3" concrete curbing along the 30 foot line from the shop to the house and then grade from there but I think it would look better to do a flower bed/retaining wall if we do the curbing. But that might look a little odd just having one small section of curbing on the entire driveway.
On the other side of the house the lot drops a good 5 foot which is where I would expect the french drain to dump out.
