Those are good questions! The artificial piles from shoveling, plowing, etc are never measured to determine snow depth. The procedures for measuring total snow on the ground is that if less than 50 percent of the ground is covered with snow, you should report a Trace for your snow depth. If there are substantial patches of snow even though the total coverage is less than 50 percent, you should note the extent and range of depths in your comments.
Glad we could keep you busy this winter
