Why don't the Firefighters shovel around the fire hydrants after a snow storm?

Whitewater is currently responsible for the maintenance of the Hudson water system. Due to limited manpower it would be inefficient and unpractical for firefighters to shovel out the hydrants. It could potentially take well over a week to shovel out the 400 plus hydrants in the Town. This would create a significant life safety concern as Hydrants may not be readily accessible in the event of a fire or other emergency. In addition, often times the snow and slush that buries the fire hydrants freezes and requires snow plows to clear around the hydrants.
