3.38 inches of rain fell in two days, the most for this week of the year since records began in 1911. The next wettest, 2.71 inches, fell in 1967.
Tierra Bonita’s center stands about 50 ft above sea level. Within three miles the land runs from 40 ft to 60 ft, a difference of 20 ft: nearly flat ground.
The section below crosses 5 rock units mapped at the surface.
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. Age: Pleistocene, less than 2.6 million years old. About 12 mi of the line.
Sand. Age: Holocene, less than 12,000 years old. About 6 mi of the line.
Silt, sand. Age: Holocene, less than 12,000 years old. About 4 mi of the line.
Sand. Age: Holocene, less than 12,000 years old. About 1 mi of the line.

Tierra Bonita has a humid subtropical climate. Summer afternoons average 98° in August; winter nights fall to about 51° in January. About 28 inches of rain fall in a normal year.
On November 14 Tierra Bonita normally reaches 80° and falls to 59°. The record high is 92°, in 1921; the record low 36°, in 2018. The most rain on this date, 1.73 in, fell in 1950.
