Had 2 pilings replaced this spring after ice damage. You need a permit from the state to the tune of $650 to do anything in the water. The cost to replace on piling and reset the 3 cluster pilings we use as an ice deflector was approx. $1,700 in addition to the cost of the permit. Not pretty but that's the game. It took us 3 months to get the permit from the state and that was when they supposedly were not to busy.
Good Luck
