Clay,

 

The 1-A Certification Letters for the Addison Road light poles should
have arrived at your office.  I meant to send this email out earlier.
There are several issues to note.

 

1.	There were 24 light poles on the FAA list provided.  I contacted
Linda Steele with the FAA and she provided data on all 24 poles which
included approximate coordinates and structure height of 39 feet.  We
plotted the location of the poles based on the FAA coordinates and then
compared them with actual light pole locations.
2.	We only located fifteen 39-foot light poles and they all
generally corresponded with a FAA coordinate.  We provided
certifications for these poles.
3.	There are not light poles at the 9 remaining FAA coordinate
locations.  A list of those FAA pole numbers is below.  I believe these
poles need to be deleted from the FAA data base. 
4.	There are five 20 to 25-foot tall light poles grouped together
on the east side of Addison Road near Arapaho.  None of the FAA
coordinates provided are near these lights.  Am I correct in assuming
that certifications are not required for these poles given there shorter
height and lack of corresponding FAA coordinate?  If certifications are
required, a FAA pole number will need to be provided.  
5.	No FAA coordinate locations fell near the railroad arms.  Linda
was also not aware of any railroad arms requiring certifications.  Do
you know how the need to survey the railroad arms arose?
