Although some new buildings along the waterway went up as far back as 2000, and several condo towers were built near its mouth more than a decade ago, most construction ground to a halt during the recession. With few impediments now, a burst of fresh projects are either being planned, under construction or completed, their crowns blending into the skyline of downtown and the Brickell neighborhood.
Just beyond the south side of the river, the $1 billion Brickell City Center — a massive complex that includes a shopping center, offices, luxury condos and a hotel — opened in November 2016 and inspired a slew of projects in its vicinity.
Across the river, the New York developer Shahab Karmely spotted a large empty lot, once a shipyard, while he was prospecting in the area in 2013. The result will be One River Point, a two-tower, 60-story condominium designed by the Uruguayan architect Rafael Viñoly that will be topped off by a pair of 14,000-square-foot “sky villas” costing about $30 million each. Spanning the gap between the towers, 800 feet in the air, a three-level private club will be encased almost entirely in glass. Construction is scheduled to start in early 2019.
Mr. Karmely, the principal at KAR Properties, said he had seen similar growth along rivers in London, Frankfurt and other cities, and regretted not diving in. “I didn’t take advantage of it,” he said while cruising the Miami River in a motorboat. “But I said to my partner: ‘This is undiscovered country. You can’t go wrong with a river. It’s dilapidated, but filled with potential.’”
Paul S. George, a history professor at Miami Dade College and the author of “Along the Miami River,” which begins its narrative with Spanish troops being entertained by Tequesta Indians on the river’s banks in 1568, said the development in recent years was nothing short of astonishing.
“This was a dormant area, completely, for over 50 years,” Professor George said. “There was nothing going on here for decades, but people have just taken to this river. It’s been a long time coming.”
Among the newcomers is the New York fashion designer Naeem Khan, who has dressed the Duchess of Cambridge, Michelle Obama, Beyoncé and Taylor Swift and who plans to move his headquarters to a site just east of the 12th Avenue Bridge. He also intends to build a factory and a 26,000-square-foot school for aspiring fashion designers there.
New developments and businesses along the waterway northwest of downtown are interspersed with boat sheds, fishing piers and modest dwellings. Tugboats tow freighters, ferries and yachts to repair yards like the century-old RMK Merrill-Stevens, which is undergoing a $30 million renovation. At some docks, the decks of cargo ships bound for Haiti and the Dominican Republic are stacked with mattresses, kitchen appliances and secondhand vehicles.
“It’s the charm of the river — it’s unique,” said Roman Jones, who made his name as a nightclub impresario in Miami Beach and opened Kiki on the River, an upscale restaurant with a Greek flavor, in April.
On a recent afternoon outside the restaurant, on North River Drive, a pair of Lamborghinis and a Ferrari awaited their owners, a sight that would have been unthinkable in the area just a few years ago. Inside, customers dined on, among other delicacies, a dish called Seafood Towers, which combined Alaskan king crab, Maine lobster, jumbo shrimp, oysters and New Zealand green-lipped mussels and was priced at $229 a plate.
At both Kiki and a similarly chic restaurant next door, Seaspice, yacht owners docked their vessels alongside the outdoor dining areas and stepped ashore for drinks and meals under the shade of large, cream-colored parasols.
On the other side of Kiki, the owner of a ramshackle boat repair dock, marine-supplies store and snack bar said he was the last of a dying breed. “I’m the only bait-and-tackle store left on the Miami River,” Pedro Gándara said in Spanish, noting that he had spent 10 years operating where the Kiki restaurant is now, before he was pushed out two years ago into the much smaller space next door.
“There were a lot of places here that serviced boats, and more than half no longer exist,” said Mr. Gándara, a 60-year-old boat mechanic who came to Miami from Cuba in 1987. “Soon, this one will no longer exist. This is the last place on the river for humble people like me.”
