In some areas of Miami Beach these days, an odd scene is taking place. There are times when the sidewalks outside eateries and boutique hotels are noticeably lower than the road next to them. Cars that are parked seem strangely raised, as though the street has been subtly raised overnight. It has, in a sense. Some roads have been raised by the city by almost three feet. It seems like Miami is doing more than just fixing infrastructure when you watch the construction workers pour concrete and adjust drainage pipes. It is attempting to keep up with the ocean.
Engineers were not the beginning of the story. The streets were flooded at first. Longtime locals still recall the afternoons when Alton Road looked like a canal due to heavy rain. Water gathered at crosswalks and infiltrated apartment buildings and shops. Watching seawater slosh across asphalt was unsettling for a city known for its sunshine and opulent hotels. The question of what happens when the water stops retreating was quietly brought up.

Geographical factors contribute to Miami’s vulnerability. Nestled between Biscayne Bay and the Atlantic Ocean, the city is situated on a small barrier island. The ground rises only a few feet above sea level in some neighborhoods. That may not sound dramatic, but water finds its way into storm drains and streets when tides rise even a little higher than normal. Miami is situated on porous limestone, in contrast to cities constructed on solid bedrock. Here, water doesn’t merely flow over the ground. From below, it seeps up.
The phenomenon is known to the locals as “sunny-day flooding.” The sight is anything but innocuous, despite the phrase’s seeming innocuousness. Seawater spreads across roads and bubbles through drainage systems on calm days during seasonal king tides. There is no rain or storm. All that’s happening is water gradually taking up space where it wasn’t before. It’s difficult to ignore the psychological change that results. In the past, flooding seemed like a transient annoyance. It now occasionally feels like a sneak peek.
Philip Levine’s election to office in 2013 was aided by this gradual realization. Levine is well-known for filming a commercial kayak ride through flooded streets during his campaign, with his dog in a life jacket by his side. Although the stunt was funny, it had a clear message. It was now impossible to overlook Miami’s flooding issue. Following his election victory, Levine promoted an ambitious and costly plan to raise the city’s streets and install strong pumps to return water to the bay.
The current infrastructure project is enormous. Dozens of pump stations that can remove water from streets during strong storms or high tides have been installed by engineers. Certain roads are being rebuilt several feet higher than they were, particularly on the western edge of the city. In areas like Sunset Harbor, where restaurant patios are now below street level, the change is evident. It appears to be a design error at first glance. It’s actually a purposeful adaptation.
The estimated $400 million price tag is controversial. That amount is comparable to the annual municipal budget of Miami Beach. Some detractors question whether raising roads will actually address the more serious issue of rising sea levels. Some contend that the city had few options. Basic infrastructure, such as roads, sewage systems, and electrical networks, becomes vulnerable if the water level continues to rise. Although it might not be a long-term solution, elevating streets buys time.
Miami is still developing in the meantime. The skyline is still dotted with construction cranes. Along the waterfront, upscale condominiums are rising, and wealthy tourists from all over the world come to attend art fairs like Art Basel. It’s a remarkable contrast. On the one hand, scientists caution that this century may see a several-foot rise in sea levels along South Florida. However, developers are still spending billions on coastal real estate. Few people can clearly see that the city is racing against the clock.
The estimates may even underestimate the rate of change, according to some coastal geologists. Seawater expands as it warms, ice sheets melt, and ocean temperatures rise. Sea levels are rising gradually but steadily as a result of all of that. However, the timeline is still clouded by uncertainty. Will the worst effects materialize much sooner or in decades? Even experts don’t agree.
The tension is subtle but noticeable when strolling along Miami Beach these days. Alongside recently raised roads, new sidewalks shine. Behind metal grates, pump stations hum softly. Waves crash against seawalls a few blocks away, which appear to be a bit closer to the street than they were in the past.
The most remarkable thing is probably how normal everything still feels. Cafés are packed. The beaches are crowded with tourists. The recently elevated streets are crawling with traffic. Beneath the everyday rhythm of city life, however, Miami seems to be preparing for a future in which everyday urban design incorporates water adaptation.
It’s unclear if raising roads by three feet will be sufficient. One street at a time, however, the city is currently moving dirt, pouring concrete, and subtly changing its elevation.
