Re: Bulkhead costs
About a year ago I paid $110 a foot for 133' of C-loc 9000 vinyl, 22 foot sheets in 10-12 feet of water with a 3' walkway along the top.
Tie-backs every six feet to treated piling deadmen, one whaler at the waterline, and another at the top edge.
Concrete "plugs" and eight foot wing wall returns at each end.
There was additional work, like a dock that is not included in that price. That is just the wall, and some of the fill, I know there was additional fill beyond the estimate that I had to buy seperately.
I had several other bids for considerably more, one for less,
That is in Virginia Beach, not your area, but not too far away either.
Be sure the contractor gives you long enough sheets. The amount below the sand is just as important as what is above. My Neighbor got a deal on his wall, but the guy only used 14' sheets in 10-12' of water. I wish him well every storm, and I also pray that he does not take me with him if he ever blows out.
