Once again, I agree but you are missing the essence of my problem. The site I am working on is in LA County which has a jumble of varying spectral response acceleration values. Even with the best printed maps that I have available to me (ASCE7-05), within a small distance Ss values can vary...
Yes, those maps will work for a ballpark figure. However I was looking for something a little more exact than trying to interpolate between two closely placed lines.

Due to the government shutdown, the website geohazards.usgs.gov is unavailable. I use this website to get all of my seismic design parameters when determining my loads.
What are other avenues to get these design parameters until the government gets up and running again?

I am running analysis on monopoles disguised as pine trees and palm trees using RISA Tower. My questions is, how does one model the faux tree branches to determine the added wind load to the structure? Are there industry standards for this or is it different for each manufacturer?
Thanks...
