Farragut is so wealthy, that it's got an old rich part (back to the mid 80's) and a new rich part (McFee Rd area).Farragut is the new rich part of Knox County. Not part of Blount County. That station may or may not have a dispatch in it now. (We joke that the adjoining area reaching into Loudon County is trying to be West Farragut)
The fire station on Campbell Station Rd was home of RM Knox Co ops dispatch until about 2007 when it was moved (and somewhat integrated) to the Knox E-911 center. Alas, it's just a fire station with HQ type operations upstairs for the Fire Dept.
And you're absolutely correct, 'East Loudon' County is basically turning into a 'West' Farragut, without the zoning and sign restrictions.
