The US Towers engineer may be speaking the truth. Standards have changed over the years. However, their advice is sound:
They did suggest I try contacting a local engineer for a possible wet-stamp on the old drawings. I'm wondering why an engineer would do this if the tower is out of compliance, as they say?
The generic tower as presented on the drawings may not comply with the general standards. Your specific installation (perhaps with a different base, or taking into account your specific soil conditions, or your specific installation location, or.or.or.) may be perfectly fine in your area. For instance, the generic tower standards may require calculating for a given snow load. You might never get that much snow in Auburn.
Maybe the engineer would do some calculations and determine that you can only put X square feet of antenna on the tower instead of the Y square feet the drawings specify, but, since you want to put less than X square feet up, you're in great shape.
So - should I try sweet-talking the county into accepting my old drawings along with a current wet-stamped copy of the updated base diagram or just forget the whole thing and start saving my money for the new tower design?
Since you're going to presumably have to pay an engineer to sign and seal the base diagram, why not have them look at the tower drawings as well, and supply a supplemental analysis. Your local engineer will (should!) know what the folks in Placer county want.
Also, have you contemplated using Placer county's third party review system? http://www.placer.ca.gov/building/third-party-plan-rev.htm
It's tough to say whether you'd save any money by doing this though. I've never been through this process, and I don't know what the target audience is. I suspect that it's not someone in your situation: a homeowner looking for permit for a small job.
