THE MINIMUM OBSTRUCTION ORDINANCE STANDARDS RELATE DIRECTLY TO THE HORIZONTAL DATUM ESTABLISHED BY RUNWAY ELEVATIONS AND NOT THE HEIGHT ABOVE THE NATURAL GRADE OF THE LAND FOR EXAMPLE AT LOCATION A AN ORDINANCE MAY REFERENCE A HEIGHT RESTRICTION X, FEET, BUT AT THAT LOCATION THE DEVELOPABLE HEIGHT RESTRICTION ABOVE THE NATURAL GRADE Of THE LAND IS ACTUALLY X, FEET. AT LOCATION B THE ORDINANCE HEIGHT RESTRICTION MAY BE X, FEET BUT THE DEVELOPABLE HEIGHT RESTRICTION MAY BE X, FEET.
