Swire Proposes Earthen Berms Off Miami’s Coast To Protect City From Storm Surge

Brickell City Centre developer Swire Properties has prepared a plan to protect Miami from future storm surge by building a series of earthen berms off the coast, according to the Herald.

The developer commissioned the plan as an alternative to one proposed by the federal government that included 20 foot-high flood protection walls, which one Miami commissioner likened to the Berlin Wall.

Swire commissioned engineering firm Moffatt & Nichol and landscape architect Edsa for their plan.

Oyster reefs would be planted around the berms as an additional flood protection barrier. Some of the berms could be planted with mangroves.

Miami-Dade is expected to decide this week on the cheaper wall plan prepared by the Army Corps of Engineers, or the berm plan, which is likely more expensive.

The Army Corps proposal would cost over $6 billion, with Miami-Dade required to pay 35% of the cost and the rest by the federal government. It’s not clear how much more the private proposal would cost.

Miami-Dade County must verbally approve the plan by February 18 or risk losing federal funding for the project for years.

A waiver to freeze the process could also be sought, but then the county could be required to pay for all additional costs for revised designs as “betterments.”

The Downtown Development Authority also previously came out against the Army Corps of Engineers proposal, and commissioned their own study for an alternative plan.

I love Swires approach. Makes a beautiful eco friendly bay walk. Adds more greenery and doesn’t block views

This would also activate that area of Brickell, with some amazing potential 🤩🤩 architectural wise. It’s been decades since anything has been done on that end

The choice is obvious, go with Swire’s earthern berms.

So Elon digs the tunnels, uses the excavated material to build the berms, saving a lot of $. More tunnels, more berms. Think that would make everybody happy?

Im not too high on these little islands disrupting the wide water views, but that wall plan is an absolute Game Changer, as in it will be an absolute killer of Miami’s asthetics and beauty. Condo values and tourism will tank.

The berm looks much better than a cement wall.
Personally, I would rather have nothing than the cement. Build that out in the ocean to slow waves.

Now that the gop is no longer in charge of the federal government and the local mayor is a Democrat, this might actually happen!

Republicans sure do love their walls. Just like good communists!

I love reading the comments under these posts and this one is a gem.
As a European who lived in the USA and who is currently back in Europe I always laugh when the Democrats are called Communists.

Americans have ZERO idea about communism – I suffered through years of it unfortunately behind the Iron Curtain, so I have first hand knowledge.

The Democrats are as far right as any right wing party in Europe, by European standards.

#1. Miami’s Mayor is a Republican (as if that matters)
#2. If you were alive long enough to remember last month, you would notice a newly erected wall around the Capitol Building.

wall in DC was to keep the insurgents out of the white house to protect president. he didn’t build anything to protect the senators Rep or Dem. But that is another story.

#1 Levine-Cava has more power than Suarez. He’s just a figurehead and besides he’s practically a Democrat. He has to pretend to be a republican so all the Cubans vote for him.
#2 A fence/wall around a building is completely different than a fence/wall in the middle of the desert.

This won’t protect from any sea level rise like the Fed’s wall would, it would only protect from storm surge during a hurricane. Higher seas will still go right around these islands and flood city streets. The 2 don’t serve the same functions.

Ft. Pierce did this around their city marina for protection from waves and it spoiled the wide water views from ground level at their waterfront park.

Fed’s wall doesn’t help with sea level rise either, these options are for surge protection only

The water will go around the ends of any wall.
This is purely to keep a huge wave from washing down city street in the event of hurricanes.
If the berm gets knocked down and preserves some of the city, great. We put the berm back for the next storm which is cheaper than rebuilding all the first floor buildings.

The berms work well, Beaches in NC and NJ both have them. Major benefit.

To deal with sea level we have to gradually raise the city (west avenue style in Miami Beach). Think in all the man made islands and infills in Dubai, Honk Kong or Singapore. Let’s raise the streets and all the City with each new construction.

$6 billion seem so out of reach even for massive concrete walls… At some point raising the streets, losing lobby heights and/or maybe losing 1 level of overbuilt parking podiums seems like it would probably make much more financial sense in the long run for these few oceanfront buildings.

What about water rentention when the water comes back out, isn’t that how most people died in New Orleans because the water could not go back out at sea? Also isn’t water coming through porous ground during high tides? Other than during hurricanes which last no more than a few days a year, does either plan help with that?

water will go around them, but it will also go back out as well.
NJ hurricane sandy. They didn’t have berms then to protect as much.

New Orleans is 6 1/2 feet below sea level. Not only did the water that came in not be able to go UPHILL into the sea, the Mississippi river was still adding water as well.
N. Orleans is a completely different terrain than Miami.

But the berms will protect from huge waves, water that does get in (which it will) can go back out the way it came.

they may consider building these further out as well to slow any wave before it gets that far inland.
Maybe off the ocean side of Virginia Key.

Concept of a flood barrier is nice but in practice may restrict floodwaters from land draining in heavy hurricane / tropical storm rainfall. It will likely block in both directions. Not sure it would be substantially effective in any event. Just say no to either expensive project. Let nature take it’s course. Wave action is limited in shallow waters of Biscayne Bay and some would be broken up by offshore reefs and shallows. Wind direction matters more.

The federal government and the us Army Corp of Engineers should hang their head in shame to come up with such a basic ugly and malignant solution. This ugly wall would cause more serious issues which Miamians would need to deal with on a daily basis. Stupid plan!
