Hi all,
A historical note about county lines: I owned a business in western Contra Costa country for many years, and at one point we had to have the property lines surveyed. What seemed like a pretty straightforward job turned into an adventure. The surveying company president called me about a week after we signed a contract and uncomfortably explained that the cost of the job had doubled! The problem was that most of the maps of west county were from the original Spanish land grants and that boundaries were approximate. There were few USGS markers, and often landmarks were based on what ship captains could see from the bay waters. So we got our property lines, sort of, but county planning was used to the situation and accepted the ambiguities. Not sure if this applies to the present situation at the creek, but I thought that it was an interesting historical note in these days of precision.
