Wednesday, June 27th, 2018 — In a private waterfront resort on the northern tip of Key Largo, nestled between tropical forest and the Caribbean, Eric Soulavy is marketing luxury for the age of climate change: Coastal homes that are all but hurricane proof. The Florida-based developer is finishing a three-story condominium project with overlapping defenses, a hydrological Fort Knox where prices start at $5 million for a four-bedroom apartment. The 27 concrete-encased units are perched 13 feet above ground with windows that can withstand 174 mile-per-hour winds. Flood pumps in the parking garage can push 20,000 gallons of water per hour 65 feet underground, fueled by a generator so large it required its own building.
