I agree with your assessment and get your drift. Homeowners in our city are not responsible for digging out hydrants on their property as I understand some are. Hydrants don't have flags, but I've never seen one buried.
There used to be a hydrant directly across the street from us. When water mains were replaced that changed, and we are now between two. I suppose in a way that's actually better. Years ago we lived in a village without city water, so there were no hydrants. Insurance rates reflected that.
