Florida Tests Wave of Living Seawalls and Elevated Urban Designs as Sea Levels Rise

MIAMI — A rapid expansion of climate-adaptive infrastructure across South Florida is turning the region into a testing ground for technologies designed to shield coastal communities and defense assets from rising seas and severe storm surges.

Among the emerging deployments are 3D-printed living seawalls developed by Miami Beach startup Kind Designs. Founded in 2024 by former attorney Anya Freeman, the company has completed 16 installations across Florida for residential, commercial, and municipal sites. It is now preparing to fortify coastal installations for the U.S. Navy alongside upcoming expansions into California and New York.

Unlike conventional flat concrete barriers that deflect waves and disrupt marine life, the company uses nontoxic concrete mixtures molded into textured surfaces that mimic natural features such as mangrove roots and barnacle clusters. Testing by researchers at Florida International University recorded 51 marine species inhabiting a single installation within one year, including water-filtering organisms like oysters and tubeworms.

The textured design is engineered to dissipate at least 45% of incoming wave energy, reducing shoreline erosion and structural overtopping during high-tide and surge events.

The engineering shift comes as roughly 129 million Americans — nearly 40% of the nation’s population — reside in coastal counties facing higher baselines for tidal flooding and extreme weather. In response, regional designers are embedding flood mitigation directly into municipal housing and public spaces rather than relying solely on single-purpose barriers.

In Miami Beach, architecture firm Brooks Scarpa Huber designed the Vista Breeze affordable senior housing complex to withstand extreme inundation. The two-building, 119-unit development sits elevated 10 feet above sea level and is engineered to endure storm surges of up to 20 feet.

To prevent saltwater degradation, the structures incorporate concrete blended with a crystalline waterproofing additive alongside zinc-coated rebar to resist corrosion. The buildings are also oriented southeast to capture prevailing winds for passive cooling, reducing energy demands during prolonged heat waves.

“In places like Miami, we’re dealing with a combination of tidal flooding, storm surge and long-term sea level rise,” said Jeffrey Huber, principal architect on the project and a professor at the Florida Atlantic University School of Architecture. Huber, who codified adaptation strategies in his 2024 manual “Salty Urbanism,” noted that design protocols tested against projected sea level rises of 5 to 9 feet are increasingly applicable to coastal cities nationwide.

In Fort Lauderdale, the city converted a former parking lot into DC Alexander Park, integrating flood mitigation with civic use. Similar strategies are being applied to municipal recreational spaces across the region. The site features a 25-foot shaded overlook and a perimeter maritime forest designed to absorb heavy precipitation and saltwater intrusion.

Regional planners are also pushing for broader, coordinated defenses. Architectural designer Aaron DeMayo, founder of Future Vision Studios, has spent a decade advancing The Coastline, a proposed regional master plan intended to construct multi-layered protections across hundreds of miles of vulnerable South Florida waterfront property.

To ensure lower-income neighborhoods have access to technical resources, the University of Miami’s Center for Urban and Community Design is establishing a community design fund. Directed by architect Thomas Klein, the initiative pairs university experts with local residents to identify and co-develop high-impact resilience projects.

The center is also launching an initiative this fall to design municipal “sponge parks” throughout South Florida, integrating green infrastructure capable of absorbing heavy rainfall and managing urban stormwater runoff.
