The Hillsboro Beach plate. Relief from Copernicus GLO-30; rivers and lakes from USGS NHD; watersheds from the USGS Watershed Boundary Dataset; roads and city limits from Census TIGER 2024.
10.48 inches of rain fell in two days, the most for this week of the year since records began in 1952. The next wettest, 4.72 inches, fell in 1954.
Hillsboro Beach’s center stands barely above sea level. Within three miles the land runs from 0 ft to 30 ft, a difference of 30 ft: nearly flat ground. Open water lies within three miles.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 64×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Sand, limestone. Age: Pleistocene, less than 2.6 million years old. About 12 mi of the line.
