The elevation of a coastal plain can vary, but typically it is at or near sea level. The coastal plain is a flat, low-lying area that extends inland from the coastline.
Coastal area soil can vary in color, but it is often influenced by the local geology and vegetation. Common colors of coastal area soil include sandy tones (light browns, tans), gray from high salt content, or hues of red and orange from iron oxide deposits.
A coastal plain is a broad level area of land that is close to sea level. Coastal plains are formed by the accumulation of sediments from rivers and coastal processes, resulting in a flat and low-lying landscape that stretches along the coastline.
People use the coastal area for a variety of activities such as swimming, fishing, boating, surfing, sunbathing, and exploring marine life. Coastal areas also provide essential habitats for diverse ecosystems and support industries like tourism and fishing.
The lowest point of the coastal area on Earth is the shoreline of the Dead Sea, which sits at approximately 1,412 feet (430.5 meters) below sea level.
It is submergent. See the related link for a more in depth explanation.

An example of an emergent coastline in the US is the Pacific Coast in California, where tectonic uplift has caused sea levels to fall, exposing more of the land. An example of a submergent coastline is the Gulf Coast in Louisiana, where the land is sinking due to subsidence, leading to more frequent flooding and submergence.
