re: Anyone here experienced Eminent Domain on property?

I have quite a bit of experience with eminent domain. Almost of it was with pipeline companies.

Since you might deal with the government, I suggest that you read about the acquisition process with the I-10 Calcasieu River Bridge project. This process is more favorable to landowners than it was when my father and his siblings had property expropriated for construction of I-10 (1950's) and a few years later for the I-210 interchange.(1960's).
