If you found a coastal city near the poles, make sure that none of the surrounding ice restricts your access to nearby naval resources. Also, keep in mind that if a water tile your city is built next to is completely surrounded by ice, you shouldn't build any naval vessels there, since they will never be able to reach the open seas.
Ice is impassable, except to air and submarine units. It provides nothing to cities.
