I live in Helsinki, Finland, and there are often clusters of buildings arranged around a garden - with space for parking, and childrens play-areas.

Snow happens every year, and it is often pushed away by mini-tractors, into giant heaps, that the children love to climb and play on.

Some parts of the ground are just left covered in ice/show for a few months though.

The paved areas are plowed and the rest is just left there.

It's not like you have a lot of snow blowing in there in an urban environment anyway.

The only way to deal with it is to make "mountains" in more open spaces (squares, large intersections, ...). You can't really take it out.

Fortunately, the courtyard itself is an open space, so long as you keep the paths to doors reasonably clear.
