Do you use your calculations for the acquisition areas?
I'd have no problem doing it if required, however my clients virtually always provide a legal description of the take. It seems that a lot of parcels end up in court these days and I'd want a surveyor stamp on the legal description to be acquired.
There was only one instance where the client, rural water company, wanted a 15' wide easement for a new line and they basically said "...we're not sure just yet where we want to run the line but somewhere in this general area on these parcels where we can take the path of least resistance around trees, creeks, etc...". I did the calculations in that case but that was the only time.
