When seawalls decide to fail

[PhilPB]

King tides and age can do unfortunate things.

Ouch! Hope no ones boat was damaged?

It’s a Florida thing, building structures on sand is always sketchy.
It didn’t “decide to fail”, it was predestined to fail.

No damage to any boats. The marina is getting the engineering drawings and estimates for the replacement now. They repaired it so no more slippage will happen.

Whoa! Let’s get the west coast involved. In Seattle, when the seawall starts to fail, instead of the simple fix of hammering I-beams on the water side to fortify the wall, they require the fix from the land side. This is exponentially more expensive to the point the owner will claim bankruptcy over the expensive fix. This is due to environmental concerns. Hilarious since it was probably dry land before it was flooded for the locks/ship canal.

Amazing. Just a little more iron oxide in an ocean full already.

Actually it’s related to the spawning salmon. Only problem is the milfoil is several feet deep.

I still don't get it. You pound in the I beams right against the existing wall though the 2 feet of weed and into the mud. The salmon lay their eggs there?

Nope. It’s DNR land, so they get to make the rules. They also dictate how many livaboards a marina can have

Greetings,
Mr. PB. I took the liberty of altering your post. They repaired it so no more slippage will for a while...Entropy.
At our place in Florida (FLL) IF repairing a sea wall, it must be of a currently accepted height above high tide. Not a simple matter of pouring the required 2'+/- on the existing structure. So an older seawall will probably have to be raised meaning, in essence, the rebuilding of EVERYTHING. New pilings and cap. The height requirement goes up every so often so a dock that meets code now may not in 5? 10? years.

Thank you RT. Yes, it will be replaced completely, probably starting early summer. My understanding is that it will be approximately 60 days for the blueprints and permits. Hopefully, they can get it done expeditiously via the use of barges and land equipment. They have shored it up and installed new water and electric for the impacted slips so the slips are good to be used now until the new seawall is installed. Once complete, it should outlast me.

When I was a bit younger I replaced an 80 ft seawall at our camp in Okeechobee Florida and it took about a month to complete by myself using a 120lb vibratory hammer to drive sheet pilings. That was a fun project but a significantly smaller scale and a whole lot less expensive.

Not a sea wall...but your picture reminded me of the marina in Patras, Greece.

Just went thru that. Hired a guy to fix a crack and he delayed, until the wall caved in. $35K later a new seawall was done. Took a year of engineering, planning and permit, with a whole bunch of crazy limitations, conditions and requirements and red tape. Typical government over reach and over reaction. But turned out nice.
