One advantage of buying our lot a year before we started building is that we now know what is going to happen when we have two years of drought, and what is going to happen when we have 30 inches of rain in 10 weeks.
The foundation construction was held up by all the rain, but should resume any day now.
For a few days after the massive rain storms, a couple of areas on our lot were seeping water, probably from the small rocky hill, maybe 40 feet high, across the street. One of those areas is part of where the driveway will eventually be located.
What, if anything, should I plan on doing about that very occasional water seepage, when the concrete driveway goes in?

First off, put down lots of large aggregate. Though you may want to tile under that, or at least install a culvert if needed to conduct runoff across it.
Bring in a cat with a blade, scoop out the driveway area down at the seepage untill you have water seeping out the inside of the cut.
Pour a rat slab there and put a drain burrito down. Backfill, compact and do your driveway as you normally would.
If you get on it real soon, there will still be water in the hillside. If not, look for a ribbon of sand or small gravel, or, a layer of impermeable clay or rock topped with permeable soil.
