Inaccuracies in the GIS map
The GIS map I am working off of for a property definitely has some inaccuracies, but I have so far been unable to determine the truth regarding sewer pipe/hookup locations. I spent over an hour at the property just looking for the manholes, but I couldn't find one that I need. I tried calling the sanitation department, but they were unhelpful. How do I find it?
Thank you!
