Stretching from the Pacific Ocean on the west to the desert on the east, San Diego County includes nearly 3 million acres of land. This area has been divided into four major physiographic areas:  coastal plains, foothills, mountains, and desert. Soils within each of these areas range from sandy loams to the heaviest clays.
