Riviera’s center stands about 40 ft above sea level. Within three miles the land runs from 0 ft to 60 ft, a difference of 60 ft: nearly flat ground.
Under the town center the state geologic map shows Silt sheet (sand, silt), from the Holocene, less than 12,000 years old.
The section below crosses 3 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, silt. Age: Holocene, less than 12,000 years old. About 20 mi of the line.

A raindrop that lands in Riviera reaches the Gulf of America by way of Los Olmos Creek: about 5 river miles.
