[Towertalk] FAA Approved Tower

[Jerry Keller]

Since your tower was in place before the airport was built, I wonder why the
airport builders didn't have to consider existing structures when they filed
their applications, etc. If they had, all that would/should have been
cleared up before the airport plan was approved, wouldn't it? I realize
airports are municipal facilities, but don't they have to get FAA approval
for their site and building plans, including environmental and community
impact statements?

Several years ago, the city of Wasilla built a new airport outside of
town and just over a couple of miles away from my home.  From the top of
my tallest tower (160') I have a nice view of the whole airport.  At the
time they built the airport I checked with the FAA and there was no
problem.  Several years later I get a visit from the FAA and the FCC.
They now think my tower is in violation and will have to be reduced in
height or painted and lit with obstruction lights.

I garner a meeting with the FAA guy who has my case.  I explain things
to him and we go over the information.  I see a problem right away, the
point they used for the determination is not where I live. After
consulting a high resolution photomap, I see their point is on the next
road over, about 1/4 mile away.  Fortunately, I have a letter giving a
set of coordinates for the big tower as determined by a licensed
surveryor as part of a property survey.  Furthermore, I have a set of
coordinates (different datum) from a high-end GPS that averaged 999
readings.  On the photomap I can see my house and the clearing for the
towers.  The coordinates I provided fall right on the same spot.  On
this basis the FAA guy uses the new coordinates and recalculates the
figures. Bingo, my tower is OK.  A few days later I receive paperwork to
that effect and the FAA guy even called the FCC to let them know case
closed.

If you're putting in a new tower and have to file with the FAA, make
absolutely sure you have the exact location.  The program he used got
the elevation from a topo database, so the horizontal accuracy affects
the vertical accuracy, too.  If a new airport is going in nearby, or
there is a significant change (added runway, longer runway, heavier
aircraft, etc.) to a nearby airport, find out as soon as possible if it
will affect you.  It could save a lot of grief later on.
