Elevation and Slope

Sacramento lies within the Sacramento Valley, a broad alluvial plain formed by the deposition of sediments from the American, Sacramento, and Cosumnes Rivers. The city’s elevation ranges from approximately 15 feet (4.6 meters) above sea level in the south to 55 feet (16.8 meters) in the north. The terrain is generally flat, with a gradual slope towards the Sacramento River. However, there are some notable exceptions, such as the American River Parkway, which features steep bluffs along the riverbanks.

Geologic Setting

Sacramento is located in the northern portion of the Great Valley of California. The valley is a geologic basin filled with thousands of feet of sediment from eroded mountains to the east and west. The underlying bedrock of Sacramento consists of ancient marine sediments that were deposited millions of years ago. During the last Ice Age, glaciers covered the Sierra Nevada mountains and sent vast amounts of meltwater into the valley, which carved out river channels and deposited immense amounts of sediment. The current topography of Sacramento is the result of these geologic processes.
