Waterproofing short foundation wall

I'm adding an extension to my home, it's on the south side of the home in downstate New York. The construction calls for more beefy floor joists than my current home. Current house has about 16 inches of foundation above grade. In order to match up the floors, which is important to me, the extension will drop about 6 inches from the existing foundation, so about 10 inches above grade. Is there anything I can do proactively to add some additional waterproof protections going a little bit higher than the foundation top/ sill plate?
