California Surveyors Forums

I was asked to provide a topographic survey for a property in Watsonville which need to be tied to the City BM datum. Nobody at the Public Works of either the City of Watsonville or County of Monterey answered the phone. Where can I get the list of BM's?

did you try the santa cruz county gis?

Thanks, Drexyl!

You might want to check those old City and County benchmarks against NGS benchmarks, especially if you are doing floodplain work. Those old level loop BMs off of 29 datum can cause problems.
