Why let sea rise sink your Miami lifestyle when you can go with the flow aboard the Arkup houseboat?

Arkup features the ingenious engineering feature of four hydraulic pilings that stabilize the vessel on the sea bottom or allow it to lift like a house on stilts above floodwaters, king tides and hurricane-whipped storm surges. South Florida sea levels are projected to rise 6 to 12 inches by 2030, 14 inches to nearly three feet by 2060, and 31 inches to nearly seven feet by 2100, according to the Southeast Florida Climate Change Regional Compact Sea Level Rise Work Group. Miami Beach and the Keys may be inundated first, but the entire region is recognized as one of the most vulnerable on the planet.

In this brave new waterworld, Arkup wants to keep you high and dry on your floating home.

Noah, who constructed his ark to withstand 40 days and 40 nights of apocalyptic rain and Biblical flooding, would approve. He probably could not afford the modern version, which has a sticker price of $5.5 million, but he would like the comfort, spacious bathrooms and retractable swimming platform.

Arkup, solar-powered and equipped with a rainwater-collecting-and-purifying system, is a self-sustaining home, a green adaptation for our blue future.

“It’s more like a house than a boat but you never lose the unmistakable feeling that you’re on the water,” said Nicolas Derouin, managing director of Arkup.

Arkup was designed and built in Miami by Derouin and Arnaud Luguet, two French engineers who live here and have a passion for the oceans and environmental preservation.

They have witnessed the impact of climate change and sea level rise in their adopted hometown and around the world. On Monday, Indonesia announced it will move its capital out of Jakarta, a swampy, flood-prone and drowning metropolis of 30 million people.

“It is happening before our eyes,” Derouin said. “Coastal areas are the most desirable but also the most at risk. Miami is implementing resiliency measures. We hope Arkup can be a small part of the solution.”

Derouin and Luguet were inspired by the Dutch floating communities of IJburg and Schoonschip.

“In the Netherlands, one third of the country is below sea level,” Derouin said. “They want to develop housing alternatives. Instead of fighting the water, live on it.”

Lake Union in Seattle has 500 permanently docked houseboats. Paris has restaurants, a hotel and is building a 2024 Olympic venue on the River Seine. Dubai has floating vacation homes. In San Francisco, where Sausalito has a houseboat community, the Danish firm BIG has proposed building an archipelago of floating villages connected by ferries on the bay. The Lincoln Harbor Yacht Club in Weehawken, N.J., which was devastated by Superstorm Sandy, may reinvent its marina as a houseboat haven.

“We decided to design a boat that looks and feels like Miami, is compatible with a subtropical climate and gives the owner the freedom and flexibility to move,” Derouin said.

Their ultimate goal is to create an affordable model, develop floating neighborhoods and partner with island hotels to build eco-bungalows on surrounding waters.

“We want to design small apartments on the water for students, townhouses for families,” Derouin said. “We want to create housing solutions for a broader audience. That’s the vision behind Arkup.”

Derouin and Luguet collaborated with Dutch firm Waterstudio and pioneering aqua-tect Koen Olthuis, who has designed a floating mosque, floating prison, floating spa and floating resort and helped conceptualize a proposed development of 29 private islands with lavish sustainable homes — a villa flotilla — on Maule Lake in North Miami Beach.

“He is an advocate of urban planning on the water,” Derouin said.

You may have noticed Arkup — which was unveiled at the Miami Boat Show in February — docked at Star Island and now Palm Island. You can see it from the MacArthur Causeway. With its floor-to-ceiling windows, it looks like a large glass box.

On board, it doesn’t look or feel like a boat. No rocking, for one thing. It has two air-conditioned levels, with 9-1/2-foot ceilings on the first floor and 8-1/2-foot ceilings on the second. There are three bedrooms upstairs with three full and roomy bathrooms — no cramped and tilting heads on this boat — and two balconies.

Downstairs, there’s an inviting living room, kitchen, dining area, two bathrooms and a small room with a Murphy bed that could be an office or guest quarters. Interior design is by Brazilian company Artefacto. A sliding outdoor deck adds 500 square feet of floor space when fully extended.

At the stern, the swim platform can be lowered into the water to create a mini pool. There’s a boat lift for your kayak or amphibious vehicle.

The bow deck has an outdoor kitchen and console controls for navigation and operating the 136-hp rotating electric thrusters, which emit no noise and require no diesel fuel, and the anchoring system, which allows adjustments of each piling to level the boat.

Arkup has a maximum speed of 7 knots and a range of 20 nautical miles that can be increased with additional battery banks or a backup generator.

“We can’t match the navigational capacity and speed of a yacht,” Derouin said. “You couldn’t cruise around the world, but you could use Arkup in the Bahamas or British Virgin Islands, for example.

“Our vessel is 75 feet long and 32 feet wide and we have the same livable space as a yacht that is 110 feet long. Arkup is for people who prioritize space and comfort over speed and range.”

Arkup’s steel hull and superstructure is built to withstand Category 4 hurricane winds (up to 156 mph). The 40-foot-long pilings, or spuds, enable the boat to anchor in up to 25 feet of water and elevate above the waves. The draft is five feet. It’s got a 4,000-gallon freshwater tank and an equal-sized tank for waste water. The 2,400-square-foot roof is covered with 36-kilowatt capacity solar panels that recharge the battery.

“A motor yacht is the opposite of sustainable,” Derouin said, pointing to a gigantic yacht parked behind Arkup and to passing motorboats that pause while curious passengers take a look at Arkup. “Large engines. Massive fuel consumption. Pollution. On Arkup you can live completely off the grid with no bills for energy or water. It is zero emission, carbon neutral. In this house, you don’t need to rebuild your seawalls or move your air conditioner to higher ground. Compared to the costs of a waterfront home, Arkup is competitive.”

Plus it’s got panoramic views of the downtown skyline and dolphins swimming by the side deck.

So far, the partners have one buyer and a waiting list of potential buyers who want to take the boat for a test drive.

“We’ve had an amazing response,” Derouin said. “Our clientele includes owners of private Caribbean islands who think Arkup is better than building a beach house. Or people who live full or part time in Miami and want a toy for the weekends, to take friends out on the bay. We have people who live elsewhere and Arkup would be their second or vacation home. And people who see it as their primary home, docked at a marina. It’s a luxury product for a niche market but our dream is to develop affordable versions with the same principles.”

Miamians who don’t want to flee could take to the sea. As oceans swell and coastlines shrink, trade house for houseboat.

“We need more entrepreneurs and scientists developing innovative ideas because climate change is not slowing down,” Derouin said. “Here’s one new way to live in harmony with the water.”

‘Floating Homes’ technology has demonstrated usefulness

By Fane Lozman
Miami Herald
September.10.2014

 

 

It is an unfortunate reality that those who currently live on Eastern Shores in Maule Lake will have to abandon their homes in the next 30 years because of rising tides. The only residents around Maule Lake will be the Amirillah floating islands, and any new developments built after Miami 21-like building codes are enacted.

The current Eastern Shores residents should be making plans now for where they will be moving once North Miami Beach condemns their residences for sea water intrusion. Instead, their fears are focused on the floating islands and reflect a total lack of knowledge about floating technology that has been proven over the last century.

Just like floating oil rigs moored to the ocean floor survive Category 5 hurricanes without being torn off their moorings, floating islands use similar technology. The land-based houses around Maule Lake would be swept clean off their concrete pads as the eye wall of a hurricane similar to Andrew made a direct hit, while the Maule Lake floating islands wouldn’t slide an inch off their permanent moorings.

Even more impressive is that these foam-cored, reinforced concrete islands are unsinkable, even after being pelted with 200-mph, windswept debris from the destroyed houses on shore.

The West Coast of the United States has thousands of floating homes that are a welcome addition to their communities in Washington, Oregon and California. The Maule Lake floating-island residences will introduce a new generation of floating homes to the East Coast. They will be completely self-sustaining and have the “greenest” footprint of any dwelling in South Florida.

The landlubbers whose attitude is that “I got to Maule Lake first and no one else should ever join me” forget one thing. The actual lake bottom is privately owned, and the submerged lands do not belong to those who are fortunate to live on its borders. Perhaps a 50-foot-high floating privacy screen running on the east side of Maule Lake would be soothing to these residents so they would not have to be jealous of their floating neighbors?

The floating islands will also help solve a simple reality that the political leaders of North Miami Beach can no longer ignore: New sources of tax revenue will be desperately needed to supplement the hidden pension demands of civil employees (i.e. police) over the coming years.

The 29 floating islands that will be assessed at $12.5 million each will bring in a staggering $363 million in new property assessments. This windfall for the city will be further magnified by the increased tax assessments for the Eastern Shores residents as their droopy neighborhood wakes up to become part of South Florida’s most unique residential community.

Like any new technology, whether it was the Wright brothers’ first airplane flight, or the $3 billon Perdido oil rig anchored in 2,438 meters of water in the Gulf of Mexico, there are “talking heads” that will refuse to accept the inevitable march of technology. It makes one wonder: How many Eastern Shores residents still have horse and buggies in their back yards?

FANE LOZMAN WON A PRECEDENT-SETTING VICTORY LAST YEAR AGAINST RIVIERA BEACH WHEN THE U.S. SUPREME COURT AGREED WITH HIM THAT HIS FLOATING HOME — WHICH THE CITY HAD SEIZED AND DESTROYED UNDER LAWS GOVERNING SHIPS AT SEA — WAS A HOUSE, NOT A VESSEL COVERED BY MARITIME LAW.

Dutch solution to Miami’s rising seas? Floating islands

By Jenny Staletovich
Miami Herald
August.23.2014

 

 

Maule Lake has been many things over the years: industrial rock pit, aquatic racetrack, American Riviera. Now it is being pitched as something else entirely: a glitzy solution to South Florida’s rising seas.

In the land of boom and bust where no real estate proposition seems too outlandish — Opa-locka’s Ali Baba Boulevard connects to Aladdin Street in one of the more kitschy bids to sell swampland — a Dutch team wants to build Amillarah Private Islands, 29 lavish floating homes and an “amenity island” on about 38 acres of lake in the old North Miami Beach quarry connected to the Intracoastal Waterway just north of Haulover Inlet.

The villa flotilla, its creators say, would be sustainable and completely off the grid, tricked out to survive hurricanes, storm surge and any other water hazard mother nature might throw its way. Chic 6,000-square-foot, concrete-and-glass villas would come with pools, boathouses or docks, desalinization systems, solar and hydrogen-powered generators and optional beaches on their own 10,000-square-foot concrete and Styrofoam islands.

Asking price? About $12.5 million each.

If this sounds like a joke, think again. This, as the Dutch say, ain’t no grap.

“We’re serious people,” said Frank Behrens, vice president of Dutch Docklands, which has partnered with Koen Olthuis, one of Holland’s pioneering aqua-tects.

Still, it’s hard not to be skeptical.

“It’s both fantastic and fantastical,” said North Miami Beach City Planner Carlos Rivero, before adding, diplomatically, “This is quite a departure.”

Behrens won’t say exactly how much the company has invested so far but suggested it is enough to take the plan seriously.

“Look who I’m sitting next to,” he said during an interview, pointing to Greenberg Traurig shareholder attorney Kerri Barsh and Carlos Gimenez, a vice president at Balsera Communications and son of the county’s mayor, both hired to help ensure the project’s success. “This isn’t like, ‘Oh, let’s buy a lake and do a project and make money.’ It’s ‘Let’s buy a lake and show people what we’re capable of.’ ”

Together Dutch Docklands and Olthius’ firm, Waterstudio.NL, have completed between 800 and 1,000 floating houses in Holland along with 50 other projects including — if there were any question about their design chops —a floating prison near Amsterdam. The team is also constructing the first phase of a 185-villa floating resort in the Maldives — Behrens said 90 have already sold. Olthius also designed a snowflake-shaped floating hotel in Norway, floating mosques in the United Arab Emirates and even a floating greenhouse out of storage containers usually used by oil companies.

The team believes that by building an extreme example of a floating house in Miami, with every bell and whistle imaginable, it can open up a new American market to a way of building that has addressed rising waters in the Netherlands for a century.

“We chose Miami because we know this city is one of the most affected cities by sea-level rise,” Olthuis said by phone from Holland. “Once it’s done, you’ll see it’s a beautiful archipelago effect in the lake.”

So can you get a mortgage? Buy windstorm insurance? Declare a homestead exemption?

Yes, yes and yes, Barsh said. Practically speaking, the barge-like structures are considered houses, not boats, she said. A 2013 U.S. Supreme Court decision on a Riviera Beach houseboat that Barsh helped argue cleared the way by declaring floating homes real estate. After the victory, Barsh started talking to Behrens — they met through the Dutch Chamber of Commerce he founded in Miami in 2011 — about Dutch-style floating homes in the United States.

“Before, there was a lack of clarity,” Barsh said. The court decision “opened up an opportunity for this development to go forward.”

Barsh, who also represents rock-mining interests, says such projects could potentially provide a valuable way to reuse rock pits scattered throughout South Florida.

But what would it mean for the manatees that lumber through the saltwater lake, which is designated critical habitat?

Protections would remain in place, the team said. And the islands, with specially contoured undersides, could provide a habitat for sea life, Behrens said.

Still, making the project fit local laws could be tricky. In a preliminary review by the North Miami Beach city staff, Rivero raised questions as mundane as the need for parking. The city’s civil engineer wondered about stormwater runoff, among other things. And police say they would need a boat from the developer to patrol the islands. There’s one other thing: North Miami Beach’s rules for such developments so far apply only to land.

Luis Espinoza, spokesman for the county’s Division of Environmental Resources Management, said county officials would need to evaluate the islands for environmental impacts. And there’s the matter of taxes.

“If it’s a permanent-type fixture, then it will be assessed as property,” property appraiser spokesman Robert Rodriguez said.

Over the next 100 years, scientists predict climate change will alter water on a global scale. Seas will swell and coasts will shrink. Weather will become more extreme, with stronger hurricanes, harder rains and higher floods. Even routine tides will rise. And almost nowhere else will those effects likely be more dire than in South Florida, where beachfront highrises and marshy suburbs sit on soggy land kept dry by a complicated network of canals, culverts, pumps and other controls.

So solving the problems of coastal living in the 21st century could be lucrative.

“Here in Miami, it’s an artificial landscape, manipulated by mankind at a very high cost,” said Dale Morris, an economist with the Dutch Embassy in Washington, D.C., who is not connected to the Amillarah project. “So to think it can be maintained at no cost is nuts. I’m an economist. Nothing is free in this world.”

The floating islands, he pointed out, do nothing to solve larger climate problems for cities in South Florida, where flooding now occurs with normal high tides in Miami Beach.

Florida, like Holland, will have to tackle gradual sea rise in addition to event-related flooding like hurricane storm surges, Dutch landscape architect Steven Slabbers said at a recent workshop on resilient design in Miami.

“It’s an inexorable, decade-by-decade phenomenon,” he said.

Considering other Dutch designs — protective dunes tunneled out to hold parking, parks that become ponds and highways that float — a rock-pit-turned-floating-housing by using drilling rig technology might not seem so farfetched.

In recent months, the last new project on Maule Lake, Marina Palms, has shown that demand for lakefront property with Intracoastal access is high. Condos in the first of two buildings, which got the glam treatment this year on Bravo’s Million Dollar Listing Miami, sold out. But Maule Lake has not always been a twinkling star in the real estate firmament. It began life as a rock pit, when E.P. Maule moved from Palm Beach in 1913. Maule Industries would become the state’s largest cement manufacturing plant before falling into bankruptcy in the 1970s after it was purchased by Joe Ferre, whose son, former Miami Mayor Maurice Ferre, managed the company.

“That area was rich in rock pits, quarries and concrete manufacturing,” explained historian Paul George, who said the rock pits pocked the largely industrial area well into the 1960s.

The porous limestone mines fill with water from the area’s high water table. The new lakes provided even more waterfront property to an area already rich with water views, creating a developer’s dream — and possibly an environmentalist’s nightmare.

In addition to worries about marine life, building on the lake may raise concerns about water quality and potential effects on the nearby Biscayne Bay aquatic preserve and the Oleta River, another protected ecosystem. There might also be a question of encroaching on some of the area’s rare open space.

“We have a history in South Florida of viewing open spaces as a pallet for more product to be built on,” said Richard Grosso, a Nova Southeastern University law professor and director of the Environmental and Land Use Law Clinic. “Florida’s always been a place where we’ve suspended the laws of nature and physics and people haven’t always taken into account that there’s a finite amount of space.”

Gimenez, the public relations executive who is also a land use attorney, said the Dutch team has already met with the U.S. Army Corps of Engineers about concerns. The team also plans to meet with neighbors. And while nothing has officially been submitted, he said no one has raised objections. The 7- to 13-foot-deep lake, he pointed out, is too deep to harbor much marine life or sea grass.

Gimenez also said floating islands are better than the alternative: filling the lake and building highrises. Once mined, rock pits are sometimes refilled with construction and demolition debris. Developers in Hallandale Beach, for example, are filling a 45-acre lake with debris to build an office park. Rivero, the planner, said a North Miami Beach ordinance prohibits the lake from being filled, although property trustee Raymond Gaylord Williams, who had the property listed with a local Realtor for $19.5 million, could challenge that.

But getting a variance from a county ordinance regulating waterways could be a feat, since so few are granted, said land use and environmental attorney Howard Nelson.

“Let’s face it, [what developer] wouldn’t rather replace a houseboat with a houseboat office,” he said. “All of a sudden you don’t have the bay anymore. You just have dock space after dock space after dock space with offices.”

Behrens, a former banker who grew up in Aruba and was CEO of a Miami-based Dutch distillery, said the team has been meeting with various regulatory agencies to size up the obstacles since 2013 and will resolve issues as they come up. They hope to have permits completed within the next year and a half, he said.

“It’s a step-by-step approach,” he said. “But we’re Dutch. …We know how to stay and how to make success.”
