Elevation

Elevation is the height of land above sea level. Elevation is shown on maps in a variety of ways including contour lines, spot elevations, hillshaded relief, color hillshaded relief and colored areas.

Use elevation information to:

  • Evaluate whether flooding or storm surge will affect your property.
  • Look for closed basins where water can accumulate during heavy rains.
  • Evaluate the flow of water over land.
  • Determine the slope of the land.

If you click on the map with the "i-tool" enabled, it will show the elevation in feet where you clicked on the map when this layer is visible.
