In Florida, the swamp-like land of a retention pond doubles as a class A+ office.
This flat stretch of land can easily survive very strong winds from a hurricane, as claimed on the sign. I’m not sure why it would need a backup generator, but I suppose “100% backup power” may mean nothing if there is nothing that needs such power. Another picture shows some birds enjoying this office for a meal.
While there are some other buildings around, signs like these are usually placed in front of the office building or its adjoining parking lot. This sign has no such placement, and certainly isn’t for the hotel in the background. That leaves the retention pond to be the office.
