Is there a public records source for Southern Pacific valuation maps? Perhaps those filed with the ICC?
I'm a land surveyor doing historical research and UP is reluctant to part with their copies of these maps unless they have a pending transaction.
Thank you in advance for you assistance.
BTW, in 1976-1977 I was a "draftsman grade 3" for SP @ the 10th floor 1 Market St., San Francisco. Being low man on the pole I was in charge of filing and indexing these maps along with making sure that the Engineering division's cars were washed and gassed, and I was official driver to Mr. Vaughn, SP's chief engineer at that time. Got promoted in 1977 and drafted updates to many val maps along with being a land title abstractor. Should of kept the job, I would have been retired by now.
