I know this isn't a CA question but you guys have come through for me so many times and I appreciate it.

Your contours are problematic, specifically the 2437 and 2438 near the plan-NW corner of the residence. Make sure the new 2438 is connected at both ends to the existing 2438. Keep in mind that the engineer is providing a 2' deep swale, and he probably did it for a good reason, so I would strive to provide the same when you revise the grading. Also, your revised driveway is going to require some tall retaining walls along both edges, something the engineer's plan avoids by using a bunch of fill. So, pick your poison: an elevated drive, or a canyon drive.

Yes, the highlighted areas are the swales. My mention that the engineer provided a 2' swale was technically incorrect - I should have said that the engineer provided 2' from the FF to the bottom of the swale. Your revised plan has only 1' from the FF elevation to the bottom of the swale.

 

Your driveway won't need retaining walls if you follow the engineer's grading plan, which requires fill. Lowering the building pad by a couple feet may help you balance the cut/fill calculations (less fill at the driveway and front yard, more cut at the hillside). But, the engineer must have a reason for their design; have you called the engineer?

Give them the FF elevs you want, then ask them to modify the plan. I'm sure they can get it done. Obviously, it will probably cost money, but maybe that can be offset by the savings in trucked fill.
