Most of the Coastal Plains in the United States have an elevation that ranges between sea level and 500 feet.

This relatively low elevation is a defining feature of the region, contributing to its flat, expansive landscapes that extend along the coastlines. The Coastal Plains’ proximity to sea level makes them ideal for agriculture, allowing for the cultivation of various crops due to fertile soils. Additionally, this low elevation supports diverse ecosystems, including wetlands, marshes, and estuaries, which provide habitats for numerous plant and animal species. The flat terrain also facilitates easy access to coastal areas, enhancing tourism and recreational activities. Overall, the elevation of the Coastal Plains plays a crucial role in shaping their ecological and economic significance within the United States.
