Talk to the airport commission, county board, local land owners ect....
somebody will have a copy of the local "avigation easements" that have been
acquired from the surrounding property owners. I've gone through the
process with land we owned next to a Wisconsin airport. It listed to what
extent we could park equipment, build, or maintain trees along each side of
and near the ends of the runways and extending outwards and upwards from the
runways.

In our case it began with a "master plan" and then the land owners were
contacted, concerns taken into account, then the plan was customized for the
location and the neighbors specific operations... to an extent. For
instance we were allowed to operate a moveable irrigation system near the
runway, but could not park it there, it could only move through the area.
Also we were required to remove any trees over 30' tall on land just across
the road from the main runway.

I've got copies of the plans around here somewhere, I would think most
adjacent land owners in your area would also have such info from the FAA.

A runway for a small town airport is .8 miles long. What is the
regulation
for maximum height of a structure .9 miles beyond the end of the runway?
Given a cessna 170b, for example, the plane could travel that .9 miles in
as
little as a half a minute. A max rate of climb of 660fpm would give it
330
ft of elevation. What is the possibility of building a tower or wind
turbine there?

Thanks
