NAD83 compared to UTM Zone North?
NAD83 compared to UTM Zone North?
(OP)
I was going to ask this in survey but that forum is not active.
I'm looking at a goby grading plan and see the coordinates are based on "UTM Zone 11 North NAD83" I understand US is divided in different zones and we are located north but I'm confused with UTM and NAD83 together. I thought they are different.

Latitude and Longitude are used to define UTM. So UTM is mapped on top of the NAD83 model. UTM mapped on top of NAD83 will be different than UTM mapped on top of NAD27 or something else.

Aside from UTM what other "common" projection topo is based on here in the US for the purpose of site grading?

I'm only seeing point coordinates in my topo and nothing whether it's UTM or state plane coordinate but maybe it's in the properties of the coordinates. I'm using Civil3d.
