County Elevations

 
Terrain throughout the county is relatively level. The mean elevation is 15 feet above sea level. Ocean coastal beachfront gradually slopes up to a dune line with top elevations of 12 to 23 feet. From the dune line there is a gradual downward slope to lake and inland waterway frontage with a width of from a few hundred feet to a half mile. From there, land slopes upward to a coastal ridge then downward to elevations of 5 to 12 feet in a drainage valley. Further, inland elevations remain relatively stable. Water velocity is seldom a problem with Palm Beach County flooding.
