Airfield scenery designs

Is there any way one can get scenery designers to adhere to the obstruction free approach paths to runways? Those designers who who place buildings and trees etc. within the "obstruction free" zones only show their ignorance to the laid down requirements. Even at ALA's obstruction free paths are required and there is nothing more annoying than having to negotiate trees and buildings which have no place on the approach and take off paths.

This should help.
