Airport Runways and Wind Turbines

I just dug out one of our maps from the Wisconsin DOT regarding one of their
easements on our property. Off each end of each runway there are clear zone
easements with a slope of 20:1 that extend a distance of 637 off one runway
and a distance of 1500' of the other end of the runway. Beyond that there
is an "avigation" easement with a slope of 34:1 that extends 1600' beyond
the clear zone easement on the approach end of the only runway with an
instrument approach at this airport.

The easements that the DOT "purchased" from us covered an area from 10 ft
above to 50 ft above the ground over 13.86 acres. After negotiations, they
paid us $5000 for the easement, the land itself later sold in 2003 for
$42,000. I also found a little brochure that the State of Wisconsin
provided that points to this site:

Thanks a lot!

A 1/20 grade from the end of the runway for 5000 feet. Looks like 200
feet
might fly.

Non-precision is 34:1.
ILS is 50:1.
