The elevation represents a distance from the sea level greater than 5 feet, 
because the original description specifies a distance greater than 5 feet 
below sea level.
Reasons:
The elevation given as a distance is the height or distance above sea level.
In the above description, elevation is a vector, given that it has both 
magnitude (distance) and direction (above sea level).
Distance is a scalar quantity, that has only a magnitude that specifies the 
space covered during motion.
An elevation of less than -5 feet indicates that distance of the location 
above sea level is less than -5 feet, which is the same as; the distance of 
the location  below sea level is greater than 5 feet.
- Less than -5 feet above sea level = Greater than 5 feet below sea level
Therefore;
- An elevation of less than -5 feet represents a distance from (below) sea level greater than 5 feet
