Height from ground for Fresh Air Intake

I need to install a fresh air intake to the basement, and wondering what sort of clearance I should have from the ground. I've got a bit over 2 feet between ground level and the subfloor. I'm in Minnesota, so I ask because of the potential for snow to block the intake.

12" above normal snow fall accumulation level.
Goose neck it.
By code, 68 sq inches of cross section. 9" round. Many contactors just run a single 6".
