County maps are highly variable, ranging all the way from non-existent to relatively accurate. Don't get trapped into thinking that property lines as shown on county maps are accurate, as they may or may not be. Some are warped to fit, which makes them nice to look at, but not very accurate.

A possibility may be to contact those who use 911 mapping.....police, ambulances, fire departments......and see where they get their maps.....I would imagine they would be pretty much up-to-date as well.
