Geography

Lafayette is located at Lua error in package.lua at line 80: module 'strict' not found.[1] and has an elevation of 36 feet (11.0 m).[2]

According to the United States Census Bureau, the city has a total area of 47.7 square miles (123.5 km²), of which, 47.6 square miles (123.3 km²) of it is land and 0.1 square miles (0.2 km²) of it (0.19%) is water.

Lafayette is located on the West Gulf Coastal Plain. What is now Lafayette was part of the seabed during the Quaternary Period. During this time, the Mississippi River cut a 325-foot-deep (99 m) valley between what is now Lafayette and Baton Rouge. This valley was filled and is now the Atchafalaya Basin. Lafayette is located on the western rim of this valley. This land, called the southwestern Louisiana Prairie Terrace is higher in elevation, and not made of wetland like much of the surrounding areas to the south and east of Lafayette. Because of this, Lafayette does not suffer significant flooding problems.

The Vermilion River runs through the center of Lafayette. Other significant waterways in the city are Isaac Verot Coulee, Coulee Mine, Coulee des Poches and Coulee Ile des Cannes, which are natural drainage canals that lead to the Vermilion River.
