In 2022, artist Xavier Cortada mapped the coastline of his home state of Florida, a peninsula whose very boundaries are defined by water. The artist traveled to 54 coastal city halls and placed a sign at each, depicting their respective elevations above sea level. By doing this at the very place where city officials make decisions about municipal budgets, as well as land use, planning and zoning, Cortada made visible the threat that sea level rise poses to each city’s future tax base.
