35.78671, -78.94545.
3- Approximate fence comers
Lat Long Comer Source
35.78685 -78.94516 NE GPS
35.78667 -78.94508 SE GPS
35.78655 -78.94575 SW Google Earth

5- RRO dropped a copy of the 2001 name change permit into Laserfiche,which had been missing from the archives.
6- BIMS needs to have the original permit date corrected to 11/10/2000.
7- The closest house at 425 Olde Thompson Creek Rd is listed on the county GIS as built in 2006. Google Earth
imagery shows the lot cleared sometime between 2/2006 and 7/2006.It is likely outside the setback anyway.
